Problems solved by technology

However, in the above methods, the feed conditioning time and temperature are uncertain, the temperature is too low or the time is decisive, and the material cannot be fully matured (conditioning temperature, conditioning time, conditioning moisture, etc. cannot meet the requirements for complete ripening), resulting in Low gelatinization degree of starch makes it difficult to kill Salmonella and other pathogens in feed, which affects the safety of feed. Indigestion of livestock and poultry causes diarrhea. In order to control diarrhea of ​​livestock and poultry, processing enterprises and farmers will add a large amount of antibiotics to control livestock and poultry. Diarrhea, which will indirectly affect human health

Abstract

The invention relates to a method for improving feed curing. The method includes the quenching, tempering and mixing treatment steps of S1, pressing a shell with the pressure intensity kept between 506.625 kPa and 810.6 kPa; S2, controlling the temperature in the shell to be 150-180 DEG C, and conducting steam quenching and tempering for 6-10 minutes till the water content is 22-32%; S3, supplementing vapor for cured feed in the shell; S4, pushing and stirring the cured feed in the vertical direction; S5, keeping the vacuum degree in a sealed tank to be -0.07632 mPa to -0.043 mPa; S6, supplementing vapor for the cured feed in the sealed tank, wherein the vapor contains 20-40% of ethanol molecules, and the temperature is controlled to be 65-85 DEG C; S7, pushing and stirring the cured feed in the horizontal direction, wherein the stirring time is 8-12 min. Through the steps, the quenching and tempering time of the material can be prolonged and the quenching and tempering temperature can be improved, starch in the feed is high in gelatinization degree, the vapor makes more sufficient contact with the material, the cured degree of the feed reaches 45-70%, and the quenching and tempering effect is improved.

Description

technical field [0001] The invention belongs to the field of feed processing methods, and in particular relates to a method for improving feed ripening. Background technique [0002] Feed from powder to granules generally has to go through raw material sampling, screening, crushing, sterilization, computer batching, conditioning, granulation, cooling, grading and other processes. Feed conditioning is to add steam before feed pelleting, and the conditioner performs moist heat treatment on the powder, so that the powder is in a state of high temperature and high moisture, which can soften the material, gelatinize the starch in the feed, kill or effectively control the feed. Salmonella and other pathogenic bacteria in the feed are beneficial to the formation of feed and improve the digestion and absorption rate of feed. After several years of development, the feed industry has gradually transitioned from the initial processing powder to pellets. The processing of feed pellets...
