RU2758294C1 - Method for recycling production waste and product returns of dairy industry for production of feed product and/or additive in composition of compound feeds for agricultural animals and poultry - Google Patents

Abstract

FIELD: processing of waste.

SUBSTANCE: invention relates to utilisation and recycling of production waste and product returns of the dairy industry for producing a feed product for agricultural animals and poultry. The method is characterised by the fact that production waste and product returns of the dairy industry are used as milk raw materials, wherein said materials are directed to a tank, then to a disperser followed by returning to the tank, the milk raw materials are neutralised with a mixture of sodium and potassium hydroxide solutions until a pH value of 6.4 to 6.5. An alkali solution is introduced into the disperser or directly into the tank, then the milk raw materials are fed from the tank into a vacuum evaporation unit, wherein said materials are heated to a temperature of 15 to 80°C, then the milk raw materials are pasteurised and supplied for spray drying using a metering pump. The finished feed product is supplied to a packaging line and directed to the finished product storage.

EFFECT: use of the invention will provide a possibility of recycling production waste and product returns of the dairy industry into feed products.

Description

The invention relates to the disposal and processing of industrial waste and product returns of the dairy industry to obtain a feed product and / or an additive in the composition of feed for farm animals and birds and can be used in the processing of prefabricated pasteurized, ultra-pasteurized and other dairy products with an expired shelf life to obtain dry a product similar to a protein-fat concentrate (BFA).

The closest analogue in technical essence to the claimed invention is a method for producing a feed product for farm animals and birds, which involves preparing a milk mixture from skim milk and milk whey, thickening the mixture components, mixing with a fat component to obtain a protein-fat emulsion and drying, characterized by that skim milk and milk whey are taken in a ratio of 20 ÷ 25: 75 ÷ 80 (RF patent No. 2021739, published on 10.30.1994).

The disadvantage of the closest analogue is that it is not intended for the disposal and processing of returns from the dairy industry (expired dairy products).

Huge volumes of expired dairy products remain unused, and therefore there is a need to create a new technology for the disposal and processing of production waste and product returns from the dairy industry to obtain fodder for farm animals and poultry.

The objective of the invention is to create a method for processing waste products and returns from the dairy industry to obtain a feed product for farm animals and birds.

The technical result of the invention is the disposal and processing of production waste and product returns from the dairy industry.

The technical result of the invention is achieved by a method of processing waste products and product returns of the dairy industry to obtain a feed product for farm animals and birds, characterized by the fact that the incoming milk raw materials - production waste and product returns of the dairy industry, are separated from the packaging, which is sent for disposal, then the dairy the raw material is sent to the tank, the amount of supplied milk raw material is measured using a flow meter or strain gauges, the milk raw material is neutralized with a mixture of sodium hydroxide and potassium hydroxide solutions to a pH of 6.4-6.5 by feeding it from the tank to the disperser and returning to the tank, and the alkali solution is introduced into the disperser or directly into the tank, then the milk raw material is fed from the tank to the vacuum evaporator by means of a pump, in which the milk raw material is heated from 15 ° C to 80 ° C, depending on the raw material, while the end of the heating process is controlled by automatic syst controlled temperature control, then the milk raw material is pumped into the pasteurizer, after the completion of the pasteurization process, the milk raw material from the pasteurizer is fed to the dosing pump and then to spray drying, after drying, the finished product is fed to the packaging line and then sent to the finished product warehouse.

It is also possible an embodiment of the method in which, after heating the product, the pump is turned off and the dispersant is turned on and the product circulates around the tank-dispersant-tank circuit, then the milk raw materials from the tank are pumped into the pasteurizer, after the pasteurization process is completed, the milk raw materials from the pasteurizer are fed to the dosing pump and then to spray drying, after drying, the finished product is fed to the packaging line and then sent to the finished product warehouse.

FIG. 1 shows a technological scheme for processing production waste and product returns from the dairy industry to obtain a feed product for farm animals and birds.

FIG. 1 the following designations are adopted:

1 - dispersant;

2 - pump;

3 - metering pump;

4 - spray drying;

5 - reservoir;

6 - vacuum evaporation plant;

7 - pasteurizer.

A method for processing industrial waste and product returns from the dairy industry to obtain a feed product for farm animals and birds is carried out as follows. Received dairy raw materials - milk, kefir, sour cream, yogurt, cottage cheese, whey, etc. (production and product returns from the dairy industry) are separated from packaging. The packaging is sent for recycling. Then the prefabricated pasteurized, ultra-pasteurized and other dairy products (raw materials) are sent to tank 5, the amount of supplied milk raw materials is measured using a flow meter or strain gauges, and the milk raw materials are neutralized (neutralized acidity, fermentation is stopped) with a mixture of sodium hydroxide and potassium hydroxide solutions to pH 6 , 4-6.5 by feeding it from the tank 5 to the disperser 1 and returning to the tank 5, and the alkali solution is introduced into the disperser 1 or directly into the tank 5, after deoxidation, the milk raw material is fed from the tank 5 to the vacuum evaporator using the pump 2. installation 6, in which the milk raw material is heated from 15 ° C to 80 ° C, depending on the raw material, while the end of the heating process is controlled by an automatic temperature control system - moisture is removed up to 50%. Next, the dairy raw material is fed by pump 2 to the pasteurizer 7, after the completion of the pasteurization process, the dairy raw material from the pasteurizer 7 is fed to the dosing pump 3 and then to spray drying 4, after drying, the finished product (BZhK) is fed to the packaging line and then sent to the finished product warehouse. ...

In the particular case of execution, after heating the product, the pump 2 is turned off and the disperser 1 is turned on, and the product circulates along the contour "tank 5 - disperser 1 - tank 5" the raw material from the pasteurizer 7 is fed to the metering pump 3 and then to the spray drying 4, after drying, the finished product (BZhK) is fed to the packaging line and then sent to the finished product warehouse.

Claims (2)

1. A method of obtaining a feed product for farm animals and poultry from dairy raw materials, characterized by the fact that production waste and commodity returns of the dairy industry are used as dairy raw materials, which are sent to the tank, then to the disperser with subsequent return to the tank, neutralize the milk raw material with a mixture solutions of sodium hydroxide and potassium to a pH of 6.4-6.5, and the alkali solution is introduced into the disperser or directly into the tank, then the milk raw material is fed from the tank to a vacuum evaporator, in which it is heated to a temperature of 15-80 ° C , then the dairy raw material is pasteurized and fed to spray drying using a dosing pump, after which the finished feed product is fed to the packaging line and sent to the finished product warehouse. 2.
