example 1

[0031] Example 1: Grind 300g of corn, 140g of wheat bran and 160g of rapeseed meal respectively to a particle size of 40 mesh sieve, then mix in proportion to add 20g of calcium carbonate, 80g of calcium hydrogen phosphate, 360g of cement, 160g of bentonite, and 40g of additives, and stir evenly It is a solid mixture. At the same time, take 360g of molasses in another container and heat it to 75°C, keep it for three minutes, then add 180g of urea and stir continuously to make the urea fully melt in the molasses, then add 200g of salt, and mix the molasses and urea to form molasses -Urea liquid mixture, mix the formed solid mixture with the molasses-urea liquid mixture, stir evenly and knead continuously, then heat it to 88°C, turn it over continuously, stir continuously to make it heated evenly, heat for 15 minutes, and knead at the same time.

[0032] Pour the heated mixture into the forming mold, the temperature of the mold is not lower than 80°C, hold the pressure for 3 minu...

example 2

[0034] This example and Example 1 only have a change in formula, including 400g of corn, 140g of wheat bran, 160g of rapeseed meal, 200g of salt, 20g of calcium carbonate, 60g of calcium hydrogen phosphate, 320g of cement, 120g of bentonite, 40g of additives, 360g of molasses, and urea 180g.

[0035] Molasses urea is the embodiment of the combination of energy and crude protein. The reasonable combination of the two can supplement the energy and protein needs of yaks in the cold season to the greatest extent, and will not cause ammonia poisoning caused by too fast degradation of urea. In terms of premix, we comprehensively considered the feed intake characteristics of cattle and sheep, the characteristics of trace element requirements and the expected licking amount of licking bricks, and combined with the lack of regional trace elements, we designed the trace element premix in a targeted manner. material.

[0036] The ingredients in the present invention are based on the p...

example 3

[0039] This example and Example 1 only have a change in the technological process. 300g of corn, 140g of wheat bran and 160g of rapeseed meal are respectively crushed to a particle size of 40 mesh sieve, then mixed in proportion, and then 20g of calcium carbonate and 80g of calcium hydrogen phosphate are added. , 360g of cement, 160g of bentonite, 40g of additives, and stir evenly to form a solid mixture. At the same time, take 360g of molasses in another container and heat it to 60°C. After keeping it for three minutes, add 180g of urea and keep stirring to make the urea fully melt in the molasses. Then add 200 g of table salt, mix the molasses, urea and table salt uniformly to form a liquid mixture, mix and stir with the solid mixture evenly.

[0040] Pour the solid-liquid mixture into the forming mold, hold the pressure for 3 minutes under the pressure given by the 6T hydraulic press, and press it into shape.

Abstract

The invention relates to the field of forages, and specifically relates to a high-temperature molding method for a nutritive block. The molding method comprises: respectively crushing the raw materials comprising corn, wheat bran and rapeseed meal, uniformly mixing to form a solid mixture according to a ratio; also heating molasses, adding urea, heating and thawing to form a molasses-urea liquid mixture; and mixing the solid mixture and the molasses-urea liquid mixture, heating, performing compression molding in a mold and drying. By employing a high-temperature molding technology, the starch in wheat bran and corn flour are gelatinized at a high temperature to form a high-viscosity starch adhesive, the adhesive and the molasses are adsorbed to the surface of solid particles together, and thus strong chemical bonds are formed. The improvement of the binding force between the particles is beneficial to improving mechanical strength of the block; because the starch adhesive is hard after cooling, the hardness of the block is enhanced, and the enhancement of the hardness is beneficial to controlling intake; and also the alleviation of the water penetration speed helps to improve water proofness of the block.

Description

technical field [0001] The invention relates to the field of feed, in particular to a high-temperature forming method of nutritional licking bricks. [0002] Background technique [0003] In recent years, large-scale captive breeding of ruminants such as cattle and sheep has developed rapidly in my country. Under the conditions of large-scale captive breeding, since ruminants can only eat a few kinds of forages, the ratio of various nutrients is imbalanced, which affects the normal growth and reproduction of animals, and then affects the economic benefits of large-scale captive ruminants. [0004] As a supplementary feed, licking bricks has been valued by European and American countries decades ago. In the 1980s, the Food and Agriculture Organization of the United Nations also promoted licking bricks in some countries in Asia, Africa and other regions. Nowadays, domestic research institutes use licking bricks as a carrier and add some trace elements to make nutritional li...
