Problems solved by technology

However, the coated dosage form amino acid still has the following disadvantages: First, the utilization efficiency of the coated dosage form amino acid is compromised
Therefore, it still cannot be absorbed and utilized synchronously with protein amino acids
Secondly, the dissolution time of the coating material is difficult to control
After the crystalline amino acid is crushed, the size is different, the shape is irregular and the particle surface is not smooth, resulting in uneven thickness of the coating material
If the local coating is too thin, there will be a phenomenon of "revealing the stuffing", which will cause the dissolution time to be too fast and cannot play the role of coating
Third, the fluidity of coated amino acids is poor
Due to the uneven particle size of the coated amino acid, the fluidity in the feed is poor, and the mixing uniformity is not good enough, which affects the absorption and utilization of the coated amino acid.
[0005] In addition, for a long time, in the process of aquaculture and feed preparation, the full utilization of nutrients and the pollution of the breeding environment have not been considered.

Embodiment 1

[0066] Select 225kg of stearic acid and put it into the chemical material tank, heat it to 80°C, stir continuously, and wait for it to melt completely; Put 230kg of hydrochloride into the batching tank, shear and stir for 10 minutes, during which the temperature should be controlled at 80°C; import the uniformly mixed material into the storage tank, and heat the temperature to 80-100°C; start the feeding spray device, and put the storage The materials in the feed tank are granulated by spraying; the finished product particles are collected by sieving with a 24-80 mesh vibrating sieve. Finally, 448 kg of finished lysine microcapsule preparations were obtained, with a particle size of 200-700 μm and a yield of 98.4%.

[0067] Replace the above-mentioned lysine raw material with essential amino acid raw materials such as methionine, threonine, tryptophan, repeat the above steps, the results are basically the same.

Embodiment 2

[0069] Select 175kg (1:1) of stearic acid and fat powder into the chemical material tank, heat to 80°C, stir continuously, and wait for it to completely melt; pump the melted stearic acid and fat powder from the chemical material tank into the batching tank, and simultaneously 180kg of accurately weighed L-lysine hydrochloride (purity 99%) is dropped into the batching tank, sheared and stirred for 8 minutes, during which the temperature will be controlled at 80°C; the uniformly mixed material will be introduced into the storage tank, and Heat the temperature to 80-100°C; start the feeding and spraying device, and granulate the prepared materials in the storage tank through spray freezing equipment; sieve and collect the finished product granules with a 24-80 mesh vibrating sieve. Finally, 348 kg of finished lysine microcapsule preparations were obtained, the particle size was 200-700 μm, and the yield could reach 99%.

[0070] Replace the above-mentioned lysine raw material wi...

Embodiment 3

[0072] Select 100kg of stearic acid and put it into the chemical material tank, heat and stir until the stearic acid is completely melted, then put in 50 kg of crushed paraffin, pump the evenly melted capsule material auxiliary materials from the chemical material tank into the batching tank, start the batching tank shear Switch off the pump, and at the same time, slowly add 100kg of feed grade DL-methionine raw material into the batching tank, shear and stir for 8-10 minutes, so that the methionine raw material, stearic acid, and paraffin mixture are melted evenly; then the uniformly mixed material is introduced into the storage tank , and heat the temperature to 80-90°C; start the feeding and spraying device, and granulate the materials in the storage tank through the spray freezing equipment; sieve and collect the finished product granules with a 30-80 mesh vibrating sieve. The weight content of methionine in the finally obtained finished methionine microcapsule preparation ...

Abstract

The invention relates to an aquatic amino acid preparation and a preparation method and aquatic feed thereof, wherein the aquatic amino acid preparation comprises an amino acid raw material and a capsule auxiliary material, and is an amino acid microcapsule preparation prepared by a preparation method of the microcapsule preparation. The preparation method comprises the following steps: (1) preparing the amino acid raw material and the capsule auxiliary material; (2) melting the capsule auxiliary material; (3) emulsifying, shearing and agitating the melted capsule auxiliary material and the amino acid raw material at high speed; (4) insulating heat for the mixed material and spraying to prepare microcapsule particles; and (5) cooling and sieving the microcapsule particles to collect the prepared finished products of the amino acid microcapsule preparation. The aquatic feed is the aquatic feed in which the amino acid microcapsule preparation is added. The aquatic amino acid preparationhas better slow release property, special controlled release property, good anti-water-solution-loss property and better free-running property, can effectively promote the synchronous absorption of exogenous amino acid and protein amino acid in the feed, and has the characteristics of low formula cost, high cultivation benefit and little influence on the cultivation water environment.

Description

technical field [0001] The invention relates to the field of feed additives for aquatic animals, in particular to an amino acid preparation for aquatic products, a preparation method thereof, and an aquatic feed added with the amino acid preparation for aquatic products. Background technique [0002] In the prior art, synthetic amino acid additives have not been widely used in aquatic animal feeds like livestock and poultry animal feeds. However, many experts in the field advocate the use of synthetic amino acids in aquatic animal feed. Studies have also proven that the addition of synthetic amino acids has some effect. Adding limiting amino acids to aquatic animal feed can improve the balance of amino acids, thereby improving the digestion and utilization of feed protein by aquatic animals. Among the amino acids, lysine plays a very important role in maintaining the normal growth and development of aquatic animals and the normal function of the nervous system. The lack o...
