A MANUFACTURING METHOD OF SOYBEAN MEAL FOR ADDING TO FEED

摘要

PURPOSE: A producing method of soybean meal for adding into feed is provided to improve the proteinoid content in milk obtained from cows without using a separate process. CONSTITUTION: A producing method of soybean meal for adding into feed comprises a step of adding lignosulphonate into regular soybean meal, and a step of drying the soybean meal containing the lignosulphonate. The drying process is repeated for 2-6 times using methods selected from the following: drying the soybean meal at 20-40 deg C for 1-10 hours; drying the soybean meal at 55-70 deg C for 1-10 hours; drying the soybean meal at 40-55 for 1-10 hours; and drying the soybean meal at 55-70 deg C for 2-15 hours. The lignosulphonate is selected from sodium lignosulphonate, calcium lignosulphonate, disulphonate salt of lignosulphonate, or a lignosulphonate solution.
