Abstract

Field of application: feed production. The purpose of the invention: cost reduction in obtaining a substitute for whole milk (milk replacer). The method of producing milk replacer for calves involves preparing a protein base, thickening it, preparing a protein-fat emulsion, mixing and drying thereof, the protein base being prepared by mixing skim milk with waste products of whey protein concentrate production in the form of filtrate, methionine, lysine and microbial protein in a ratio of 2904: 1528: 1: 1.8: 42, and upon receipt of a protein-fat emulsion, waste products from the production of whey protein concentrate in the form of a filtrate, microbial protein, non-dairy fats, phosphatidine are mixed d concentrate, fat-soluble vitamins in a ratio of 78.7: 3.6: 13.7: 1: 0.024. Eprin is used as a microbial protein. 1 s p. f-ly, 3 tab.

WITH

The invention relates to feed production.

The goal is to reduce costs in obtaining a substitute for whole milk.

EXAMPLE 1 For the preparation of a protein base, pasteurized at 76 ° C for 20 s and 5807 kg of skim milk, 3066 kg of filtrate, as well as 2 kg of methionine, 3.5 kg, are pasteurized at 76 ° C for 20 s. lysine, 84 kg of eprin (with a ratio of components 2904: 1528: 1: 1.8: 42). After mixing, the protein base is sent to a vacuum evaporator to thicken up to 42% solids.

In another double-walled vessel with a jacket, a protein-fatty emulsion is prepared from pasteurized 944 kg of filtrate, 43 kg of air, 164 kg of bone fat, 12 kg of phosphatide concentrate and 0.288 kg of fat-soluble vitamins (0.08 vitamin A, 0.008 kg of vitamin D2, 0, 2 kg of vitamin E) with a component ratio of 78.7: 3.6: 13,: 1: 0.024. The protein-fat emulsion is mixed using a pump, filtered and homogenized at 10 MPa and a temperature of 60 ° C.

In an intermediate container with a stirrer, a co-condensed protein base and a protein-fat emulsion are fed. The mixer operates throughout the entire process of feeding the product to the dryer.

The yield of dry milk replacer-1000 kg. The product is characterized by the following characteristics: mass fraction of fat 17%, mass fraction of moisture 7%, mass fraction of ash 8.5%, protein 26%, acidity of the recovered product 24 ° T. Skim milk saves compared to prototype

10%, i.e. 0.6 tons of skim milk per 1 ton of dry product.

Example 2. In a double-walled container with a jacket, 19.6 kg of bone fat and 2.3 kg of feed phosphatide concentrate, 0.012 g of vitamin A, 0.001 kg of vitamin Yes, 0.03 kg of vitamin E (25% concentration) are added and heated up to 60 ° C. Up to 7 kg of the filtrate is heated in a separate container, a he indicated fat base and 4.5 kg of enrin are introduced into it. The resulting mixture was kneaded with a mixer using a pump, filtered and sent for homogenization with the addition of 9 MPa and a temperature of 60 ° C. The resulting emulsion of 18% fat is mixed with a mixture of 572 kg of skim milk, 290.3 g of the filtrate, which previously introduced 0.23 kg of methionine, 0.5 kg of lysine and 10.5 kg of epine. The mixture is stirred for 15 minutes, pasteurized at 76 ° C for 20 s and cooled to 8 ° C.

The yield of liquid milk replacer is 1000 kg. The product is characterized by the following indicators: mass fraction of fat 2%, mass fraction of solids 10%, chalk 2: 6%, density 1027 kg / m, acidity 23 ° T,

Example Z. 7.6 kg of confectionery fat, 8.6 kg of phosphatide concentrate, 0.04 kg of vitamin A, 0.004, kg of vitamin Yes and 0.1 kg of vitamin E (25% solution) are added to a double-walled container with a jacket; and heated to 65 ° C. 341.5 kg of filtrate are heated in a separate container to 65 ° C, the above-mentioned heated fat base and 20 kg of sprin are introduced into it. The resulting mixture of 20% fat is kneaded with a stirrer, filtered and homogenized at a pressure of 11 MPa, and a temperature of 65 ° C. In a separate container, a mixture of 1328.5 kg of filtrate, 2435 kg of skim milk, 40 kg of etrin, 1 kg of methionine, 1.7 kg of lysine is prepared and sent to thicken to a solids content of 43%. The thickened mixture is mixed with the emulsion and sent for pasteurization at 76 ° C with an exposure of 20, followed by cooling to 8 ° C.

The yield of condensed milk replacer-1000 kg. The product is characterized by the following indicators: mass fraction of fat 8%, mass fraction of protein 12.4%, solids 440%, acidity 100 ° T.

Example 4. 164 kg of bone fat, 12 kg of phosphatide concentrate, 0.08 kg of vitamin A, 0.028 kg of vitamin D2, 0.02 kg of vitamin E (25% solution) are added to a double-walled container with a jacket and heated to 60 ° C. Pasteurized at 76 ° C with 20 with a shutter speed of 944 kg, the filtrate is heated to 60 ° C
