The weight ratio of the sodium hydroxide solution to the cottonseed cake is 0.92:1, so that the pH value is about 10.5. The interlayer of the agitator is heated by steam to maintain the temperature between 75-85 ° C, and the heating is continued for 10-30 minutes. After cooling, it can be fed. For storage, drying reduces the moisture to below 7%. 8x4 China Feed Industry Information Network - based on feed, serving livestock
