Embodiment 1
[0025] (3) Pulverization: pulverize the dried material to a particle size of 0.425mm with a pulverizer;
[0026] (4) Extrusion and cutting molding: Put the pulverized material into the feeder and enter it into the twin-screw extruder for extrusion. The parameters of the extruder are set as: screw speed 90r / min, the sleeve from the feed port The four-stage temperature of the outlet is 30°C, 40°C, 50°C, and 70°C in sequence; the extruded material is extruded through the rice grain-shaped die hole, and is cut into a rice grain shape by a cutter;
[0027] (5) Filling, sealing and sterilization: Fill the shaped rice grains directly into packaging bags without drying, add water according to the mass ratio of rice to water at 1:0.5, seal and sterilize at 121°C for 20 minutes to obtain moisturizing instant rice.
