Embodiment 1
[0033] Embodiment 1 carries out following steps successively:
[0034] 1. Material selection: Choose 1000 kg of dry corn starch that meets the national standard GB / T8885--2008;
[0035] 2. Roasting and sterilization: Put 1,000 kg of the above-mentioned dry corn starch into a covered and controllable interlayer roasting pot with a volume of 20 cubic meters, carry out 110 ° C ≤ material temperature ≤ 160 ° C, stir and stir fry at a speed of 20 times / minutes, continuously stirring and frying for 120 minutes for roasting and sterilization to obtain dry and sterilized material;
[0036] 3. Sterilization and cooling: move the above-mentioned dry sterilized material into the interlayer cooling pot with circulating water for cooling at room temperature in the interlayer, and stir the agitator driven by the motor in the pot at 20 times / min. Use circulating water for cooling in the interlayer to cool down, and cool to below 70°C within 40 minutes;
[0037] 4. Screening: Use a sieve wit...
Embodiment 2
[0040] Embodiment 2 steps 4, 5, 6 are the same as Embodiment 1, the difference is
[0041] 1. Material selection: choose 2000 kg of dry corn starch that meets the national standard of GB / T8885--2008;
[0042] 2. Roasting and sterilization: Put 2000 kg of the above-mentioned dry corn starch into a 20 cubic meter covered and controllable interlayer roasting pot, carry out 110°C ≤ material temperature ≤ 160°C, stir and stir fry at a speed of 30 times / minutes, continuously stirring and frying for 140 minutes for roasting and sterilization to obtain dry and sterilized material;
[0043] 3. Cooling: move the above-mentioned dry and sterilized material into the interlayer cooling pot with circulating water for cooling at room temperature in the interlayer, and stir the agitator driven by the motor in the pot for 30 times / min. The cooling in the layer is cooled with circulating water, and the material temperature is cooled to below 70°C within 40 minutes.
Embodiment 3
[0044] Embodiment 3 steps 4, 5, 6 are the same as Embodiment 1, the difference is
[0045] 1. Material selection: choose 1500 kg of dry corn starch that meets the national standard of GB / T8885--2008;
[0046] 2. Roasting and sterilization: Put 1,500 kg of the above-mentioned dry corn starch into a 20 cubic meter covered and controllable interlayer roasting pot, carry out 110°C ≤ material temperature ≤ 160°C, stir and stir fry at a speed of 25 times / minutes, continuously stirring and frying for 130 minutes for roasting and sterilization to obtain dry and sterilized material;
[0047] 3. Sterilization and cooling: move the above-mentioned dry sterilized material into the interlayer cooling pot with circulating water for cooling at room temperature in the interlayer, and stir the agitator driven by the motor equipped in the pot at 25 times / min. Use circulating water for cooling in the interlayer to lower the temperature, and cool to the material temperature below 70°C within 40...
