The technological process for the production of condensed canned food with sugar consists of the following main operations: 1) acceptance and preparation of raw materials and components, 2) normalization, 3) pasteurization, 4) homogenization, 5) preparation and addition of sugar syrup, 6) thickening, 7) cooling of condensed product, 8) packaging, 9) packaging (rolling) and 10) storage.
Acceptance of raw milk and its preparation (cleaning, cooling and reservation) is carried out in the same way as in the production of other dairy products. The components of the finished product according to the recipe are prepared in accordance with the current documentation.
After preparation, the milk is normalized taking into account the content of fat in the finished product, dry milk residue, dry skimmed milk residue (SOMO) and the ratio of fat and SOMO.
The normalized milk mixture is pasteurized at a temperature of 85-95 or 105-112°C without aging. For low-fat canned food, skimmed milk and buttermilk are pasteurized at 75-77°C with a holding time of 10 minutes and at 85-90°C without holding. Before pasteurization, a 25% aqueous solution of a stabilizer salt can be added to normalized milk in an amount of 0.008-0.01% of the milk mass.
Before thickening, homogenization of milk is allowed. It is applied in winter time, as well as for canned food with a viscosity of less than 2.5 Pa * s. Homogenization is carried out at a temperature of 60-65°C and an operating pressure of 8-10 MPa, and for condensed canned coffee - at 75-80°C and 10-12 MPa.
Sugar syrup is prepared by dissolving required amount sugar in drinking water temperature 60-70 ° C. After mixing sugar with water, the mixture is brought to a boil and cleaned. Sugar syrups are recommended to be prepared with a sugar concentration of 65-70%. In order to prevent the splitting (inversion) of sucrose, as well as sugaring and thickening, the syrup cannot be kept for more than 20 minutes from the start of boiling until it is mixed with milk. The temperature of the syrup during mixing should be 90-95 ° C. Sugar syrup can enter the vacuum apparatus of the installation mixed with milk or in stages: syrup - milk - syrup. Before entering the evaporator, the milk mixture with sugar syrup, milk or syrup is filtered.

Figure 3 shows a diagram of a technological line for the production of whole condensed milk with sugar in a continuous-flow way, where: 1.6 - containers for raw milk; 2, 4, 7 - pumps for milk; 3 - container with a tensometric device; 5, 22, 33 - plate coolers; 8, 17 - counters for milk; 9 - disk filter for milk-sugar mixture; 10, 20 - plate heaters; 11 - pump for milk-sugar mixture; 12 - pump for recirculation; 13 - container for dissolving sugar; 14 - sugar dispenser; 15 - receiving hopper; 16 - receiving chute; 18 - pump for skimmed milk; 19 - container for skimmed milk; 21 - cream separator; 23 - buffer tank for cream; 24, 27 - pumps for cream; 25, 28 - plate pasteurizers; 26 - container for storing cream; 29 - capacity for the normalization of the mixture; 30 - pump for the mixture; 31 - vacuum evaporator; 32 - homogenizer; 34, 36 - containers for the finished product; 35, 37 - pumps for the finished product; 38 - bank washing machine; 39 - packing machine; 40 - seaming machine; 41 - washing dryer; 42 - labeling machine; 43 - packing machine.
Condensation (cooking) is carried out at the boiling point:
The duration of thickening of the product in the vacuum apparatus should be minimal. To determine the readiness of the product, a sample is taken, cooled to 18-20°C and the density, mass fraction of dry matter and organoleptic indicators are determined.
The density of condensed whole milk with sugar at 50°C is 1280-1320 kg/m?. The mass fraction of solids in the finished product according to the refractometer at 20°C is 73.8-74%. The consistency of the product sample at 50°C should be slightly viscous. The product should flow easily from the spatula or hydrometer when removed from the cylinder in which the density of the sample was determined. The condensed product from the vacuum evaporator is sent for cooling. For this purpose, coolers-crystallizers and vacuum coolers are used. The product is cooled to a temperature of 18-20°C for 40-60 minutes.
When the condensed milk with sugar is cooled, the crystallization of lactose begins. This process is uncontrollable and results in the formation of large crystals. To obtain a high quality product, it is necessary that the size of lactose crystals does not exceed 10 microns. If larger crystals are formed, then the consistency of the condensed product becomes powdery and even sandy. To intensify crystallization and the formation of small crystals of lactose, a seed is introduced into the condensed product - dry finely crystalline lactose with a crystal size of 2-3 μm. The amount of seed corresponds to 0.2% by weight of the product. Before adding lactose, it is heated at 105±2°C for at least 1 hour. After adding lactose to condensed milk, the number of crystallization nuclei increases, which contribute to the formation of small crystals. As a seed, you can use condensed milk from a previous production. Its amount should be at least 10%. The crystallization temperature of lactose is 25-35°C. The correct crystallization of lactose is judged by its size. According to GOST 2903, the homogeneity of the consistency of the product is determined by the average size and distribution of crystals in groups, and their number is counted under a microscope using micrometer eyepieces. The size of the crystal is measured along the length of the face. All crystals are divided into 4 groups. According to the average size of crystals in each group and their number, the average size crystals in sweetened condensed milk. When determining the size of crystals milk sugar measure at least 100 crystals. Depending on the size of the milk sugar crystals, the following consistency of the product is distinguished: up to 10 microns - a consistency that is uniform throughout the mass; from 11 to 15 - mealy; from 16 to 25 - sandy; more than 25 - crispy on the teeth. Samples are also taken from chilled condensed milk to determine physical, mechanical and biochemical parameters. If these indicators correspond to the regulatory documentation, then the product is sent for packaging and rolling. The finished product is packaged and rolled into cans No. 1, 7, 13, metal tubes No. 13, as well as plywood-stamped or wooden jellied barrels and metal flasks. If the product does not meet the requirements of GOST and technical specifications in terms of water and fat content, it is normalized (standardized) after thickening with water skimmed milk or cream.
Skimmed milk and cream added to the condensed product are pasteurized at the same temperature as the milk used for condensing. The temperature of the water, skimmed milk and cream used for standardization must be equal to the temperature of the condensed milk being standardized. If sweetened condensed milk contains more water than intended regulatory documentation, then it is allowed to mix it with a product of a lower moisture content of another brew.
The production of condensed milk in Russia, according to experts, is quite promising and profitable business. Condensed milk is in high demand in the consumer market. Sweet and healthy treat bought up in large quantities not only the population. A demanded type of sale is the wholesale sale of condensed milk to enterprises engaged in the manufacture of confectionery and bakery products.
The advantage of the business is that it is quite easy to buy equipment for the production of condensed milk today. The domestic market offers customers a wide range of both individual devices and fully equipped production lines. The cost of equipment depends on the country of the manufacturer, configuration and power. You can install modern, compact equipment in a relatively small area. Mini production of condensed milk does not require special knowledge and large financial investments. But before you buy equipment and start making condensed milk, you need to familiarize yourself with the technological process and some of the nuances of running such a business.
When choosing ingredients for the production of condensed milk, one should take into account the fact that a standard condensed milk production line is equipped with a vacuum evaporator designed to get rid of excess liquid and is designed to process natural whole raw materials.
If it is intended to use a dry milk mixture, then in this case you will have to spend money on purchasing an expensive unit - a homogenizer. The advantages of powdered milk over whole raw materials are convenient delivery, relatively low cost and shelf life.
Installed in 2011 new GOST condensed milk (GOST R 53436-2009) clearly indicating the composition of the product:
Ascorbic acid can be used as an oxidizing agent, and potassium and sodium derivatives act as a stabilizer. In rare cases, it is possible to use a dry mixture with the addition of animal fats. The production of condensed milk in accordance with GOST is not only compliance with the specified composition of the finished product, the content of protein and fat in it. Appearance, color, taste and packaging of condensed milk must also meet a certain standard. Container according to GOST is made of environmentally friendly, non-toxic material, and the label should inform the buyer about the manufacturer, composition and shelf life of the product.
But the cost, and hence the final price of a quality delicacy, is quite high. Therefore, despite impeccable taste and beneficial features, whole condensed milk is produced in a small volume.
More often, the technology for the production of condensed milk involves the use of the following ingredients:
Additives that are part of the finished product, significantly reduce its cost. The low price attracts the attention of buyers, both retail and wholesale. Therefore, store shelves are littered with precisely these products.
A beginner should study the question of how condensed milk is made from different ingredients. The information provided will help you choose available technology, and determine the configuration of the automated line.
The technological process for the production of condensed milk is not complicated and consists in the following scheme:
When opening a mini-production of condensed milk, which converts milk powder and additives into a sweet treat, an entrepreneur must purchase a melter, a reactor, a homogenizer, and a pump. A larger enterprise will require the addition of digesters and additional vessels to the production line.
If a businessman decides to open a condensed milk production plant that processes natural fresh raw materials, then crystallizers, a pipeline equipped with a receiving funnel and a control panel must be added to the listed devices.
The price of equipment for condensed milk from dry mixes and additives can reach 3,500,000 rubles. and higher.
These are high-capacity lines for giant factories producing more than 200 kg of products per hour, including:
Entrepreneurs who open the production of sweetened condensed milk in a small village do not need such a powerful installation. In this case, attention should be paid to more compact and less powerful equipment, for example: UMS-4, plus VMS-100 reducing agent. The line produces about 23 kg of condensed milk within 8 hours.
The cost of an extended line varies from 300,000 rubles:
Milk consumption per 1 kg of the finished product will be 2.5 liters (dry mix - 0.3 kg), and sugar will need about 0.45 kg. That is, the cost of 1 kg of condensed milk is 60 rubles. ( fresh milk), 45 rubles. (powdered milk).
An automated device for making whole condensed milk from natural fresh raw materials costs about 550,000 rubles. and is equipped with a separator that analyzes the composition and fat content of the mass. After adding or removing cream, the milk enters the pasteurizer for processing that increases the shelf life of raw materials.
Sugar is introduced into the cooled mass, and it enters the vacuum evaporator. After the excess liquid is removed from the total mass, the condensed milk enters the crystallizer for cooling. The introduction of crushed lactose helps to avoid crystallization of a homogeneous mass. Packaged condensed milk is stored or delivered to the customer.
For some time now, condensed milk, beloved since childhood, has begun to raise more and more questions. And the first of them: is it milk?
COLOR. Real condensed milk is white, with a creamy tinge. Light brown color indicates that the product is overheated, that is, the technology is broken.
SMELL. It would be superfluous to remind that favorite treat should not have foreign odors and tastes. Mold on the inside of the jar indicates poor sanitation
CONSISTENCY. High-quality condensed milk will not create a feeling of "sand" on the teeth. Liquid mass gives out a lack of protein in the raw material (for this reason, the finished product may delaminate). Thick - a sign of increased acidity of milk or high temperature storage of condensed milk
A delicacy familiar from childhood is condensed milk, which you can not only buy in the store, but also cook it yourself at home. Sweet, viscous, healthy treat can be eaten with a spoon, added to pastries, served with pancakes. Unlike a store-bought condensed product, there is no homemade harmful components- only natural ingredients. Treat yourself and your family to a delicious treat by cooking it in a saucepan on the stove, bread maker or autoclave.
Presented on store shelves a wide range condensed milk. delicious treat in tin can produced in different parts of the world. The modern economy has relaxed the requirements for the quality of the condensed product produced. An industrial dessert is prepared with palm oil, and from dairy products, and not at all from tasty and healthy cow's milk. To avoid non-uniform crystallization of sugars and to achieve a stable structure, microcrystals of lactose are added to the product.
Housewives are looking for recipes for home cooking without harmful additives. Production technology for ordinary kitchen is not difficult, you can cook delicious treat without much hassle. The cooking procedure and recipe change only slightly. The dairy product is boiled with granulated sugar over low heat until desired consistency. There are several secrets for making the perfect condensed product:
High requirements for condensed milk back in 1952 are not met today. This product contains only carefully cleaned and tested whole milk and sugar. As a result of boiling, condensed milk with a fat content of 8.5% came out. A special production technology made it possible to preserve maximum amount useful substances in the final product even with prolonged heat treatment.
The main secret technological process- long-term pasteurization at a temperature of 60 to 65 degrees. Such heat treatment does not destroy valuable macro- and microelements, vitamins, proteins, milk fats contained in a whole dairy product. Thanks to modern kitchen appliances (multi-cookers, pressure cookers), you can follow this technology at home. Even in the absence special devices there are methods that will prevent milk from leaking onto the stove, but the temperature will have to be adjusted manually.
Among homemade recipes, there are many ways to cook condensed milk. Modern recipes are prepared not only on the whole product, but also on powdered milk or take infant milk formula as a basis. From natural supplements use coffee or cocoa, which give the dessert special taste. You can prepare a healthy treat without harmful ingredients. Follow the instructions, keep the proportions so that the treat comes out flawless. Do not increase the cooking time. In a digested dish, the process of crystallization of sugars will begin in a few days.
The recipe for condensed milk without extraneous additives according to GOST is suitable for true connoisseurs of the taste and quality of this sweet delicacy. Granulated sugar plays the role of a preservative in the recipe. Even an opened jar can be stored in the refrigerator for 30 days. The cooking process is long, but you can prepare the product for the future. Condensed milk at home is prepared faster from a high-fat product. If you want a thick product, replace regular sugar reed. It is characterized by strong crystallization and will make the consistency denser.

Condensed milk product- This is a delicacy that is loved by adults and children. Not only beautiful taste characteristics make it valuable for human nutrition. When it comes to a natural product made from cow's milk and sugar, it is difficult to overestimate its beneficial properties. The product contains the following substances:
because of high calorie product, nutritionists recommend limiting consumption to 2-3 teaspoons per day. Even this small amount of treats will strengthen your teeth, bones and hair due to the high content of calcium and fluoride. There is a lot of glucose in condensed milk, which will cheer you up, increase physical and mental activity improves emotional state. Experts recommend introducing a high-quality condensed product into daily diet nursing mothers, as a means of increasing the amount of milk produced.
Given the popularity of condensed milk among consumers, you involuntarily think about organizing your own business. Indeed, the production of condensed milk is a profitable and cost-effective direction. Moreover, many confectionery companies use condensed milk to make their products. Indeed, the demand for this delicacy is huge.
This circumstance can create some difficulties for novice entrepreneurs who want to produce high-quality condensed milk in accordance with GOST. However, if you position yourself as a conscientious and high-quality manufacturer, then the brand of your delicacy will be out of competition.
To date, there is an approved GOST 53436-2009. According to these standards, only fresh milk and additional ingredients. It is allowed to use ascorbic acid as an oxidizing agent.
Also, the new standards classify products, depending on the level of fat content:
High-quality condensed milk, which meets the established standards, is produced by the process of evaporating water from raw materials. After that, sugar is added to the resulting concentrate.
The whole production process finished products based on the passage of raw materials according to a specific processing scheme:
It is also possible to organize the production of condensed milk based on powdered milk. According to the technology, the process is similar to that described above, however, in this case, the process of evaporation of moisture from the milk mixture can be excluded. It is enough to dilute the raw material with drinking purified water. The resulting product must be kept for several hours. After that, a similar sequence of procedures is carried out, as with whole milk.
Also, the technological process provides for the preparation of condensed milk with various fillers. For these purposes can be used fruit supplements, cocoa, coffee and so on.
Most modern producers use the so-called combined method for the production of condensed milk. The line is built in such a way that it is possible to produce condensed milk from powdered milk and whole milk.
To organize your own workshop for the production of condensed milk from raw milk, you need to purchase the USM-4 unit. The price range of the installation varies between 20,000 - 25,000 rubles. Or any other similar installation for the production of condensed milk at home.
For a small workshop, several such installations will be needed. During the seasons when natural milk As prices rise significantly, entrepreneurs prefer to use VSM-100, which makes it possible to use powdered milk for the production process. The installation cost is 190,000 rubles.
Also, the automatic line must be provided with a cooling unit, the cost of which varies between 450,000 - 500,000 rubles.
For packaging finished products, you need to buy the appropriate equipment, the cost of which is 700,000 rubles.
To purchase a complete set of equipment, you may need about 1,500,000 rubles. Of course, you can cut costs by purchasing used equipment. To find a line at the best price, you can use electronic bulletin boards or visit the official website of the manufacturer.
Before opening your own business need to be thought through carefully in advance. Any business needs to start with legalization. First of all, the entrepreneur must register his “newly minted” enterprise with the Federal Tax Service (Federal Tax Service). To open an activity, an LLC or IP is suitable. The following list of documents will be required:
It is also necessary to indicate when registering a legal entity. faces OKVED codes. To select a code, you need to select the appropriate type of activity according to the description. A four-digit code must be indicated in the application.
It is also necessary to ensure that the manufactured products must comply with the established GOST, only in this case it will be certified and tested.
It is necessary to pay attention to the room where the production line will be located. The room must comply with sanitary standards, have an emergency evacuation plan, and be equipped with a fire alarm.
The production process should be managed by experienced technologists. Employees should not be allowed to work without concluding an employment contract. The employer must also ensure that employees undergo a medical examination and have an appropriate medical certificate. Business organization may require:
Raw milk and sugar are the main raw materials for the production of condensed milk. Before organizing a business, it is necessary to take into account a number of difficulties that arise with whole milk:
You can conclude a contract for the supply of whole raw materials with various farms. The more raw materials purchased in bulk, the greater the discounts.
When the production process is established, the entrepreneur receives large volumes of finished products. It's time to think about its implementation. The best distribution channels are:
You can also pay attention to the confectionery companies that use the delicacy to prepare their products.
An approximate calculation must be carried out based on the work of the entire workshop. For calculations, we take three USM-4 installations. For one shift they are able to produce 65 kg of condensed milk. The cost of one kg is 50 rubles. The average wholesale price of one kg is 120 rubles. Monthly revenue will be about 170,000 rubles.
It is also worth considering possible risks in business, which include:
Highly important question which should be taken seriously. Some kind of inscription or an individual drawing that will be applied to the container can act as a brand. For example, "Sweet tooth", "Taste of childhood", "Teddy bear" and so on. In this matter, it is extremely important to show maximum creativity. The chosen brand should not repel a potential consumer. The logo should evoke pleasant emotions and childhood memories.
