Embodiment 1

[0066] [Example 1] directly form granule by fermented liquid

[0067] In this example, Corynebacterium glutamicum CJM107 (KCCM-10227) was prepared with 1 l of process water as a standard, and contained 50 g of raw sugar, 10 g of peptone, 10 g of yeast extract, 5 g of urea, and KH 2 PO 4 4g,K 2 HPO 4 8g, MgSO 4 ·7H 2 O 0.5g, biotin 100μg, thiamine HCl 1,000μg of the medium 18l, at the culture temperature of 35 ℃, culture medium pH 6 ~ 8 range for 98 hours to complete the lysine fermentation process. The lysine content in the fermentation broth was 18%.

[0068] After concentrating the filtrate of the fermented broth to a level of 55.2 wt% of the total solid content by concentrating under reduced pressure, the pH is adjusted to 3.5-3.6. The pH adjustment was performed with sulfuric acid, and after the pH adjustment, the concentrated solution was left in a 60° C. environment for 2.5 hours.

[0069] After the gDNA decomposition process, the concentrated liquid was injected...

Embodiment 2

[0071] [Example 2] Adding free lysine in the fermentation broth to adjust the content

[0072] The fermented liquid (with a lysine content of 14.5%) produced through the fermentation process under the same conditions as in Example 1 was concentrated to a total solid content of 51.5 wt%. 8 g of free lysine (manufactured by CJ Co., Ltd.) was added thereto, and after mixing in a mixing box, the same conditions as in Example 1 were used to prepare granules.

[0073] The finally obtained product has a lysine content of 68%, a protein content of 14%, a moisture content of 0.13%, and a surface density of 665.5kg / m 3 , Inorganic matter content 2.50%, 3% for particle size range of 0-500μm or less, 28% for particle size exceeding 500μm or less than 1000μm, 67% for particle size range of 1000μm-1300μm or less, and 2% for particle size exceeding 1300μm.

Embodiment 3

[0074] [Example 3] Add content regulator to adjust content in fermented liquid

[0075] The fermented liquid produced by fermentation under the same conditions as in Example 1 was used, and its lysine content was 20%, and the total solid content was 25.8%.

[0076] After the fermented liquid is concentrated, an excipient with a water content of 9.0% prepared by dissolving 0.22 kg of cornstarch in 0.5.L of water is added to the concentrated liquid as a content regulator, and mixed in a mixing box.

[0077] Concentrate the filtrate of the fermented broth to a solid content of 50.5 wt% by concentrating under reduced pressure, and then make granules under the same conditions as in Example 1.

[0078] In this example, the finally obtained product has a lysine content of 66%, a protein content of 14%, a moisture content of 0.24%, and a surface density of 682.5kg / m 3 , Inorganic matter content 1.88%, particle size range 0-500μm or less is 4%, more than 500μm and 1000μm is 29%, more ...

Abstract

A process for the production of animal feed additives from fermentation broth containing L-lysine is disclosed. The process does not require filtering of biomass in order to remove the biomass and produces granulated lysine of controllable lysine purity with a high bulk density, low viscosity, and a low hygroscopic property which does not require the addition of an anti-absorptive substance. In this process, a lysine fermentation broth produced after slant culture, flask culture, seed process, and cultivation process is concentrated to a solid content of about 44-52%. A product with low hygroscopicity, high bulk density, and the intended amount of purity is produced after being mixed with substances for controlling the amount of purity and granulated by coating the surface of the seeds. This process enables a production of animal feed additives having a lysine-HCl purity of at least 65%, a water content of at most 3%, and a bulk density of 670 + 50kg / D.

Description

technical field [0001] The invention relates to an animal feed additive mainly composed of granulated lysine fermented liquid with high surface density, stable lysine content and simple production process and a production method thereof. [0002] In the granulation production stage, specifically, after concentrating the L-lysine fermentation broth, adding any one or more of excipients and free lysine groups to the concentrate, and putting it into a granulator with a size of 200 to 500 μm Then spray the mixed concentrated solution from the bottom of the granulator to coat the microparticle seed crystals to increase the volume of the microparticle seed crystals. 5%, exceeding 500 μm, 20-30% below 1000 μm, 60-70% exceeding 1000 μm and below 1300 μm, and 5% exceeding 1300 μm. Background technique [0003] The powdery lysine feed used in the past, due to strong scattering, poor working conditions, large loss, and damage to workers. Although the content of lysine is high, a larg...
