Embodiment 1

[0030] After the culture solution containing sugar and inorganic salt is sterilized, Escherichia coli is inoculated, fermented, and sugar and ammonia are supplemented during the fermentation process. After the fermentation is completed, tryptophan fermentation feed liquid is obtained, wherein the sugar content is 0.3-0.5% (weight), the thalline is 7-8% (weight), tryptophan 2-4% (weight), and inorganic salt 1%. (weight), and the rest is water.

[0031] The tryptophan fermentation feed liquid is dried into feed powder by a spray dryer. The working principle of the spray dryer is: the air passes through the filter and heater, enters the air distributor on the top of the drying tower, and then enters the drying chamber uniformly in a spiral shape. The feed liquid is pumped from the feed liquid tank through the filter to the centrifugal atomizer on the top of the drying tower, so that the feed liquid is sprayed into extremely small mist droplets. Dries to a finished product in a ...

Embodiment 2

[0042] The difference between embodiment two and embodiment one is that the corn cob is crushed into small particles with a particle size of about 80 mesh with a hammer mill, and the corn cob particles are dried rapidly under the condition of 55 degrees Celsius to make the moisture content Stay at 0.5%. After placing the corncob particles and the powder in a closed space according to the weight ratio of 3:1, calcium carbonate is added, and then air at 70 degrees Celsius is introduced into the closed space to make the corncob particles and the powder tumbling. The water content of the obtained tryptophan additive premixed feed is 1%, the particle size is 60 mesh, and the premixed feed contains 1% of calcium carbonate.

[0043] In order to verify the stability of the obtained tryptophan additive premixed feed, the following comparative tests were performed. According to the method disclosed in the invention of 00122268.6, the application number is 00122268.6 to prepare comparat...

Embodiment 3

[0048] The difference between embodiment three and embodiment one is that the corn cob is crushed into small particles with a particle size of about 60 mesh with a hammer mill, and the corn cob particles are dried rapidly under the condition of 60 degrees Celsius to make the moisture content Stay at 4%. After the corncob particles and the powder are placed in a closed space according to the weight ratio of 3:1, sodium chloride is added, and the sodium chloride is 0.1% of the total amount of the corncob particles and the powder. Then feed the low-temperature air of 40 degrees Celsius in the closed space to make the corncob particles and the powder tumbling. The water content of the obtained tryptophan additive premixed feed was 6%, and the particle size was 40 mesh.

[0049] In order to verify the stability of the obtained tryptophan additive premixed feed, the following comparative tests were performed. According to the method disclosed in the invention of 00122268.6, the ap...

Abstract

The invention belongs to the technical filed of fodders and relates to a tryptophan additive premix; the processing method of the tryptophan additive premix comprises the following steps: (1) powdering: fermented feed liquid containing tryptophan is spray-dried to obtain powder; (2) crashing: core cobs are crashed into core cob particles with 40-80 meshes; (3) drying: the core cob particles are rapidly dried to obtain the particles with less than 5 percent of water content at 50-60 DEG C; (4) water spraying and mixing: the core cob particles and the powder are placed in a closed space according to weight ratio with 3-4:1, a water sprayer is arranged at the upper part of the closes space for spraying water, and air flows in the closes space to lead the core cob particles and the powder to be stirred. The tryptophan additive premix has high stability and good feeding effect.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to a tryptophan additive premixed feed. Background technique [0002] Additive premixed feed is an intermediate compound feed product made by mixing one or more trace components with carriers or diluents according to requirements and uniformly mixing them. Trace components include various trace mineral elements, various vitamins, synthetic amino acids and other additives. Carriers are particles capable of carrying or adsorbing trace amounts of active additives. [0003] Tryptophan is an essential amino acid. Of all the amino acids, tryptophan is considered the least abundant in foods. Although rare, tryptophan plays a very important role in regulating animal appetite and maintaining the health of the body. Studies have shown that tryptophan can regulate piglet appetite and promote feed intake, and tryptophan deficiency will cause a decrease in pig feed intake. Especially in the we...
