Practice of improving the production process of high-temperature cottonseed meal
In order to reduce the content of free gossypol of high-temperature cottonseed meal and promote its application in livestock and poultry feed and aquafeed,the improvement of the production process of high-temperature cottonseed meal and the problem and its solution in the actual production process were introduced.Combined with the actual production,in the high-temperature cottonseed meal production process of the pretreatment process shell-kernel separation and screening process was adjusted,before the bare seed shelling adding wind power seed cleaning machine,self-unloading magnetic separator and spider mesh dust removal unit and other equipments,and adjusting the mesh size of riffle screen,using rotary vibration sieve stead of plane rotary sieve,and after screening,the material was softened,stir-fried and extruded,then defatted by box-chain extractor as well as removed solvent by controlling of the steam to ensure the quality of the high-temperature cottonseed meal.In addition,the feed moisture of extruding was controlled at 9%-10%,and an early quality warning mechanism was established.After the improvement of the process,the content of free gossypol in high-temperature cottonseed meal can be stably controlled below 800 mg/kg,and the quality of the product has been significantly improved.
