Description

The invention relates to the sugar industry and can be used in the manufacture of sugar-containing products in the form of granules.

A known method of producing a sugar-containing granular product, which consists in the fact that glucose with a granule size of 1.0-3.0 mm is poured onto the perforated bottom of the granulator and mixed using a mixer, while heated air at a temperature of 80 ° C is supplied from below through the perforated bottom. and an aqueous solution of glucose with a CB content of 80% and at the same temperature as the air is sprayed from above through nozzles. Then the glucose granules are dried by supplying hot air to their layer (SU 961745, publ. 1982).

This method does not allow to obtain uniform in composition and sufficiently durable granules. In addition, enrichment of this product with vitamins, mineral salts, and trace elements necessary for humans is not provided, which significantly reduces its physiological value.

The closest analogue of the proposed invention is a method for producing a sugar-containing granular product, in which sugar syrup is mixed with molasses and fine crystalline sucrose is added, the resulting solution is sprayed onto a layer of seed granules. The result is granules formed from a combination of sucrose microcrystals and dehydrated syrup containing molasses (US 3619293, publ. 1971).

The disadvantage of this method is that the resulting product does not have a sufficiently high physiological value and has a limited range.

The technical result of the invention is to increase the physiological value of the finished product and expand its range

This result is achieved in that the proposed method for the production of a granulated sugar-containing product involves spraying and drying the sugar-containing solution onto a seed granule layer, the sugar-containing solution comprising sugar, molasses and fruit juice or fruit juice concentrate, the molasses content and the fruit juice or juice concentrate being in a solution of 10-50% by weight of the solution, and the total solids content in the solution is 80-85%.

The use of a mixture of sugar syrup and molasses and fruit juice concentrate in the production of a granulated sugar-containing product can significantly expand the range of products due to the fact that it is possible to obtain a product with the addition of one type of juice (or concentrate) or several juices. Thus, a product having the taste and smell of various fruits will be obtained. Since molasses and fruit juice concentrates are rich in vitamins, mineral salts, trace elements and biologically active substances, the special introduction of any additives into the sugar-containing product is not required. The result is a product with valuable nutritional properties and a varied flavor.

The essence of the proposed method is illustrated by examples of its implementation.

An aqueous molasses solution is prepared and the calculated amount of sugar is dissolved in it so that the total solids content of the solution is 80-85%, and the molasses content and the fruit juice or juice concentrate added with sugar are 10-50% by weight of the solution. The resulting sugar-containing solution is heated to a temperature of 60-80 ° C and fed into a granulator, which is selected from among those known, for example, those described in RU 2181774 or SU 961745. For the granulation process, a heated solution containing sugar, molasses and fruit juice concentrate or concentrates is sprayed using nozzles on a layer of seed granules. The air heated to a temperature of 80-110 ° C is supplied through the perforated bottom of the granulator with the formation of a so-called fluidized bed. In addition, for a more uniform distribution of the sprayed sugar-containing solution, the product is mixed with blades located in the granulator.

As it was established empirically, it is advisable that the content of molasses and concentrate (concentrates) of fruit juices in the sprayed mixture be 10-50% by weight of the solution. If the content of molasses and fruit juice concentrate is less than 10%, then the taste of the fruit will not be felt in the finished product, which reduces the consumer properties of the final product. If their content exceeds 50%, the granulation process sharply slows down and granules are formed with a loose structure, and the dust formation process also begins to increase rapidly.

The solids content in the mixture should vary between 80-85%. If their content is less than 80%, then the process, as determined experimentally, requires more energy to remove moisture, and if more than 85%, it is very difficult to control the granulation process due to the low fluidity of the initial product.

Example 1. Prepare an aqueous solution of molasses at room temperature. To do this, take 2.5 liters of water, and then add 1.0 kg of molasses and 10.7 kg of sugar, so that the total solids content is 80%, and the content of molasses and fruit juice concentrate added with sugar is 12% by weight of the solution . To do this, based on the calculation, add a concentrate of orange juice in an amount of 0.8 liters. The process of dissolving sugar is carried out while heating the solution to a temperature of 60 ° C and served in the granulator, which is described in SU 961745. As the product on which the solution is sprayed, the previously obtained granules are used. To carry out the granulation process, a heated solution containing sugar, molasses and fruit juice concentrate is sprayed using nozzles. The air heated to a temperature of 110 ° C is fed through the perforated bottom of the granulator and the produced product is mixed with the help of the blades with which the granulator used is equipped. The result is 12.24 kg of granulated sugar-containing product with an orange flavor, containing physiologically useful substances contained in molasses and fruit juice.

Example 2. Prepare an aqueous solution of molasses. To do this, take 2.1 liters of water, and then add 1.4 kg of molasses and 10.1 kg of sugar, add a concentrate of orange and apple juice in a total amount of 1.4 liters - 0.4 liters of orange and 1 liter of apple, so the total solids content of the solution is 81%, and the molasses content and fruit juice concentrates added together with sugar are 19% by weight of the solution. To carry out the granulation process, a heated solution containing sugar, molasses and orange and apple juice concentrates is sprayed using nozzles onto the finished product layer obtained by the method described in Example 2. Air heated to a temperature of 100 ° C is fed through the perforated bottom of the granulator and mixed using the blades that the used granulator is equipped with. The result is 12.44 kg of granulated sugar-containing product with the taste of apple and orange and containing physiologically useful substances contained in molasses and fruit juices.

Example 3. The method is carried out, as in example 1, with the following ratios of the substances used: water - 1.7 l, sugar - 9.2 kg, molasses - 2.6 kg, pineapple juice concentrate, 1.5 l, solids content the solution is 82%, and the content of molasses and pineapple juice concentrate is 27%.

When implementing the method, the following technological parameters are used: solution temperature 70 ° C, temperature supplied for drying air 90 ° C.

The result is 12.44 kg of granulated sugar product with pineapple flavor.

Example 4. The method is carried out, as in example 1, with the following ratios of the substances used: water - 1.7 l, sugar - 9.2 kg, molasses - 2.6 kg, pineapple juice concentrate, 1.5 l, solids content the solution is 82%, and the content of molasses and pineapple juice concentrate is 27%.

When implementing the method, the following technological parameters are used: the temperature of the solution is 70 ° C, the temperature of the air supplied for drying is 90 ° C.

The result is 12.68 kg of a granulated sugar product with pineapple flavor.

Example 5. The method was carried out, as in example 1, with the following ratios of the substances used: water - 1.2 l, sugar - 8.8 kg, molasses - 3.0 kg, pineapple juice concentrate - 1 l and apple - 1 l, the solids content in the solution is 84%, and the content of molasses and concentrates of pineapple and apple juices is 33%.

When implementing the method, the following technological parameters are used: the temperature of the solution is 70 ° C, the temperature of the air supplied for drying is 90 ° C.

The result is 12.9 kg of granulated sugar product with a taste of pineapple and apple.
