Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a slow-release non-protein nitrogen feed and its preparation method, which adopts a drying method, overcomes the shortcomings of uneven coating of the slow-release non-protein nitrogen feed prepared by the puffing method, and prolongs the feeding time of the feed. The sustained release time reduces the chance of ruminant poisoning; the prepared feed tastes sour and sweet, which improves the palatability of ruminants

Embodiment 1

[0017] The drying equipment that this embodiment adopts sees figure 1 . It includes a mixer 1, a heating device 2, a rotary heat exchanger 8, a first cyclone separator 3, a second cyclone separator 5, a third cyclone separator 7, an induced draft fan 6 and a collector 4; The inlet of the inner tube of the rotary heat exchanger 8 communicates with the outlet of the heating device 2 through a pipeline, and the outlet of the inner tube of the rotary heat exchanger 8 communicates with the inlet of the third cyclone separator 7 through a pipeline; The bottom outlet of the third cyclone separator 7 is connected to the dust collection device, and the upper outlet of the third cyclone separator 7 is communicated with the inlet of the induced draft fan 6;

[0018] The inlet of the outer tube of the rotary heat exchanger 8 is connected to the outlet of the mixer 1 through an auger conveyor, and the outlet of the outer tube of the rotary heat exchanger 8 is separated from the first cycl...

Embodiment 2

[0029] The equipment that adopts is with embodiment 1.

[0030] The difference from the examples is: 1) Weigh 20 parts by weight of corn flour and 20 parts by weight of urea, mix and pulverize, and then pass through a 100-mesh sieve to obtain a mixture;

[0031] 2) Add the mixture described in step 1) into mixer 1, add 10 parts by weight of molasses, mix well, and then transport the three mixtures in mixer 1 to the rotary heat exchanger through the conveying auger gelatinization at 140~150°C in the outer tube;

[0032] 3) The gelatinized product is cooled by the first cyclone separator and the second cyclone separator, and crushed after cooling to obtain the slow-release non-protein nitrogen feed.

Embodiment 3

[0034] Different from Example 1, the raw materials of following parts by weight are adopted:

[0035] 70 parts of urea, 30 parts of molasses, 60 parts of soybean meal powder.

Abstract

The invention discloses a sustained release non-protein nitrogen feed and a preparation method thereof. The method comprises the following steps of: mixing 20 to 70 weight parts of corn meal or soybean meal and 20 to 70 weight parts of urea, crushing, and sieving by a sieve of 60 to 100 meshes; adding 10 to 30 weight parts of molasses, mixing uniformly, feeding into a rotary dryer, and gelatinizing at the temperature of between 120 and 150 DEG C; and finally, cooling a gelatinized product by a cyclone separator which is communicated with the drying equipment, and crushing to obtain the sustained release non-protein nitrogen feed. By the method, the disadvantage that the sustained release non-protein nitrogen feed prepared by an expansion method is not coated uniformly is overcome, the sustained release time of the feed is prolonged, and the probability of the toxication of ruminants is reduced; and the prepared feed has acid and sweet taste, and improves the palatability of the ruminants.

Description

technical field [0001] The invention relates to an animal feed additive and a preparation method thereof, in particular to a slow-release non-protein nitrogen feed suitable for ruminants and a preparation method of the feed. Background technique [0002] Non-protein nitrogen such as urea has the advantages of high industrial output, low price, and high nitrogen content, with a nitrogen content as high as 46%. Microorganisms in the rumen of ruminants at home and abroad can use non-protein nitrogen substances such as urea as nitrogen sources to synthesize and transform them into bacterial proteins, and then under the action of digestive enzymes, they are digested and utilized by ruminants just like natural proteins. However, because the hydrolysis rate of urea in the rumen of ruminants is too fast, exceeding the rate at which rumen microorganisms can use urea to synthesize bacterial protein, the urea that cannot be used by microorganisms in the future will be decomposed under ...
