Embodiment 1

[0015] In the reactor, add 43 parts of 37% formaldehyde solution (16 parts on a dry basis), and add 1 part of catalyst, adjust the pH value of the reaction system to 78 with sodium carbonate, then heat the reactor to 50 ° C, Add 100 parts of urea, react for 2 hours, then add 10 parts of soybean meal, 150 parts of corn flour and 1 part of food attractant (Youtuanbao), mix well, raise the temperature to 105°C, and react for 30 minutes to gelatinize the starch, Dry and generate aroma through moderate Maillard reaction, cool to natural temperature, and then pulverize through a 3mm sieve to obtain a yellow-brown or yellow-brown powder product.

Abstract

The invention relates to a hydroexymethyl complex preparation, which is a supplementary protein feed for the ruminants processed and made by utilizing urea and formaldehyde as the main raw materials. Based on the hydroexymethyl low molecule condensed product formed by the reaction of the urea with the formaldehyde, the invention is formed by fully mixing and adding soybean meal, corn meal, phagostimulant and catalyst to the hydroexymethyl low molecule condensed product to carry out a low-temperature thermal reaction. The dry base weight portion of each raw material is that 100 portions of the urea, 16 to 25 portions of the formaldehyde, 100 to 200 portions of the corn meal, 10 to 50 portions of the soybean meal, 1 to 2 portions of the phagostimulant and 1 to 2 portions of the catalyst.

Description

technical field [0001] The invention relates to a hydroxymethyl urea compound preparation, which uses urea and formaldehyde as main raw materials to process and make protein supplement feed for ruminants. Background technique [0002] At present, the most commonly used non-protein nitrogen species at home and abroad is mainly urea. Urea is a compound formed by ammonia and carbon dioxide under high temperature and high pressure. Its total nitrogen content is 46%, and its crude protein content is 288%, which is equivalent to soybean meal protein. 7 times. Generally speaking, urea itself is non-toxic, but the ammonia released by urease hydrolysis in the rumen has toxic effects on animals. Therefore, in order to ensure the maximum nutritional effect of urea, the most important thing is to control and slow down the release rate of ammonia after urea is ingested into the rumen, so as to maintain a low ammonia concentration in the rumen, thereby preventing ammonia poisoning and pr...
