Embodiment 1

[0035] The preparation method of the rumen-passing-protected tryptophan granules of this embodiment comprises the following steps:

[0036] Step 1: Take 30.5kg of L-tryptophan and 1kg of water respectively, after mixing evenly, make strip-shaped granules in the granulator, and then spin the boiling shot in the shot blasting machine, dry at a temperature of 50°C 80min, until the water content is ≤10wt%, and the dried tryptophan pellets are obtained.

[0037] Step 2: Pour the dried tryptophan pellets obtained in step 1 into the storage tank of the fluidized bed, adjust the atomization pressure to 3.5kg / cm2, the rotating speed is 90 rpm, and the inlet air temperature is 35°C. The outlet air temperature is 25°C.

[0038] Step 3: Take 68.5kg of C 16 -C 18 After the fatty acid is melted, it is then cooled to 80° C., and then coated onto the surface of the fluidized pellets in step 2 at a mass ratio of 68:30 to obtain rumen-passed tryptophan granules. In each rumen-passing-protec...

Embodiment 2

[0040] The preparation method of the rumen-passing-protected tryptophan granules of this embodiment comprises the following steps:

[0041] Step 1: Take 50.5kg of L-tryptophan and 1.5kg of water respectively, mix them evenly, and make strip-shaped particles in the granulator, and then spin and boil the shot blasting in the shot blasting machine, at a temperature of 60°C, Dry for 65 minutes until the moisture content is ≤10wt%, and the dried tryptophan pellets are obtained.

[0042] Step 2: Pour the dried tryptophan pellets obtained in step 1 into the storage tank of the fluidized bed, adjust the atomization pressure to 3.5kg / cm2, the rotating speed is 95 rpm, and the air inlet temperature is 40°C. The outlet air temperature is 30°C.

[0043] Step 3: Take 48kg of glyceryl monostearate, after melting, cool to 90°C, and then coat the surface of the fluidized pellets in step 2 with a mass ratio of 48:50 to obtain rumen-protected tryptophan acid granules. In each rumen-passing-pro...

Embodiment 3

[0045] The preparation method of the rumen-passing-protected tryptophan granules of this embodiment comprises the following steps:

[0046] Step 1: Take 45.5kg of L-tryptophan and 1.5kg of water respectively, after mixing evenly, make strip-shaped particles in the granulator, and then spin and boil the shot blasting in the shot blasting machine, at a temperature of 70°C, Drying for 50 minutes until the water content is ≤10wt%, to obtain dried tryptophan pellets.

[0047] Step 2: Pour the dried tryptophan pellets obtained in step 1 into the storage tank of the fluidized bed, adjust the atomization pressure to 3.5kg / cm2, the rotating speed is 100 rpm, and the air inlet temperature is 45°C. The outlet air temperature is 35°C.

[0048] Step 3: get the polypropylene resin IV of 53kg, be dissolved in the 95% (v / v) ethanol of 5l, be 53:45 by mass ratio then, be coated on the surface of the pellet of fluidization in step 2, namely obtain over Rumen protected tryptophan granules. In...

Abstract

The invention discloses a preparation method of rumen bypass protection tryptophan particles, and belongs to the technical field of nutrient substances of ruminants. The preparation method of the rumen bypass protection tryptophan particles comprises the following steps: S1, taking tryptophan, preparing the tryptophan into pellets, and drying the pellets to obtain dried tryptophan pellets; S2, fluidizing the dried tryptophan pellets; and S3, taking saturated fatty acid and salt thereof and / or an enteric slow-release packing material, carrying out melting and cooling, and coating the surfaces of the fluidized pellets with the molten material to obtain the rumen bypass protection tryptophan particles. By adopting the preparation method disclosed by the invention, firstly, tryptophan can be completely coated, so that the finally prepared rumen bypass protection tryptophan particles can more effectively pass through rumens of ruminants; and secondly, the utilization degree of the coating layer by ruminants is increased, so that the coated tryptophan can be completely released and fully utilized by ruminants.

Description

technical field [0001] The invention relates to a preparation method of rumen-passing protected tryptophan granules, belonging to the technical field of ruminant nutrients. Background technique [0002] Tryptophan is one of the essential amino acids for animal growth and development. It is an aromatic amino acid and has a special indole group. It is precisely because of this structural particularity that tryptophan not only participates in the synthesis of body proteins, but also is an amino acid with metabolic activity. Its metabolites are serotonin, melatonin, NAD (nicotinamide adenine di Nucleotides), NADP and nicotinic acid are also involved in the regulation of animal feeding, growth, reproduction, immunity, anti-stress and other aspects, and are called important precursor substances. [0003] Esteban et al found that oral administration of tryptophan to rats could significantly increase the levels of 5-hydroxytryptophan, 5-hydroxytryptamine and plasma melatonin in the...
