Starch residue is the residue of peas, broad beans, potatoes, sweet potatoes, and other raw materials to produce starch food. Due to the different raw materials, the nutritional content is also different. The water content of fresh powder residue is very high, up to 80%~90%. Because it contains soluble sugar, it is easy to cause lactic acid bacteria to ferment and have a sour taste. The longer the storage time, the greater the acidity, and it is easy to be contaminated by molds and spoilage bacteria and deteriorate, loss of feed value. Therefore, it needs to be dried when used as feed.
