The new feed processing method of the present invention relates to a processing method of roughage, ammoniated roughage, concentrated feed and pre-treatment of fermented raw materials. It is characterized by adding a certain amount of water to the feed raw materials to make the moisture content of the raw materials reach 12-70%, placing them in a sealed pressure-resistant treatment tank, and introducing saturated steam. In the first stage, the temperature of the materials is maintained at 120°C-170°C. ℃, the holding time is 2 minutes to 30 minutes. In the second stage, the temperature is quickly raised to 160℃~230℃ and maintained for 30 seconds to 15 minutes. Rapidly introduce compressed air or saturated steam, increase the pressure to 6~40kg/cm2, and open immediately The discharge valve sprays out the raw materials, which are processed into feed or fermentation products.
