Description

In auth. Sat N ° 264155 describes a method for the production of feed, which means that urea is added to the carbohydrate part of vegetable raw materials, such as molasses, starch, hydrolytic production waste, and heated at a temperature of 55-65 ° C for 45-50 hours with occasional stirring. Next, the mixture after heating is neutralized with 20-25% NaOH solution.

The resulting feed contains the following composition, g / l; glucosylurea 196, mannosylurea 101, xylosylurea 52.2, urea 142, Sugar 206.5.

The purpose of the invention is the acceleration of the reaction of the carbohydrate part and urea and the simultaneous production of feed consisting of a mixture of glucosylurende and urea phosphate, which is digestible by animals. The resulting feed in the rumen of animals is not exposed to the harmful effect of the urease enzyme, which increases the efficiency of nitrogen and phosphate utilization by ruminants. This is achieved by the addition of concentrated phosphoric acid with excess urea into the reaction medium, which accelerates the process of urea interaction with the carbohydrate part of vegetable raw materials and at the same time excess phosphoric acid reacts with urea residues to form urea phosphate.

As a result of this process, a mixture of glucosylureides and urea phosphate is contained in the final product.

The technological process is as follows.

Carbohydrate-containing raw materials, such as molasses or starch, are hydrolyzed together with urea and concentrated phosphoric acid at the rate of: 1 mole of acid and 1.5% urea per 1 mole of monosaccharides. The mixture is heated at a temperature of 60 ° C and maintained for 3.5-4 hours.

The excess acidity is neutralized with calcium carbonate and ammonia. After that, chrigotovleppy feed is fed to cattle.

Example 1. Getting feed from molasses. 636.9 kg molasses containing 50% PB, 203.4 kg 85% PzRO, and 159.7 / sg urea are loaded into the reactor.

The mixture is mixed, heated to temperaureura 60 ° C and maintained at this temperature 3.5-4 us. Food of approximately composition is obtained, o / c: sucrose 6, ureid 8.42 MWRO. | 4.68, fructose 13.15, urea phosphate 21.2, water 31.

Example 2. Getting food from starch-containing raw materials. 436 l of water, 247 kg of starch and 158 kg of 85e / oh NZRO.1 are loaded into the hydrolyzapnarate. The mixture is heated at a temperature of 98 ° C for 3-5 hours with continuous stirring. Then, the hydrolyzate mass containing 20–25% PB is fed into the reactor, into which 99 kg of urea is loaded, is not moved until the latter is dissolved, heated to a temperature of 60 ° C and maintained at the same temperature for 3-5 hours.

The approximate composition of the resulting mass, / o: glucose 4.5, PzP04 4.68, ureid, 16.7, phosphate urea 14.18, water 54.7.

Subject invention

Method of feed production by ed. St. Lo 264155 characterized in that, in order to accelerate the reaction of the carbohydrate part and urea and simultaneously produce a mixture of glucosylureides and urea phosphate, together with the urea, concentrated phosphoric acid, which interacts with the urea waste, is introduced into the reaction medium with urea phosphate .
