Embodiment 1
[0022] (1) Set the temperature of the constant temperature high-speed mixer to 140°C, take 14kg of microcrystalline cellulose, 11kg of soybean protein fiber, 7kg of etherified starch, and 8kg of glycerol, and mix microcrystalline cellulose and soybean protein Put the four materials of fiber, etherified starch and glycerin into the constant temperature high-speed mixer, and perform high-speed mixing until they are uniform;
[0023] (2) Add 4kg of calcium propionate and 14kg of cross-linked hydroxypropyl esterified starch to the constant temperature high-speed mixer. After adding calcium propionate and cross-linked hydroxypropyl esterified starch, the temperature of the high-speed mixer Lower it to 120°C, and then carry out high-speed mixing;
[0024] (3) Take the mixed material out of the high-speed mixer and carry out extrusion granulation. The extrusion method is twin-screw extrusion. The temperature of the first stage of extrusion is 165°C, the temperature of the second stag...
