Embodiment 1
[0022] Embodiment 1 The present invention carries out the steps of steam explosion gelatinization treatment to raw grain corn of liquor as follows:
[0023] 1) Raw material pretreatment: wash and soak the corn in hot water at 93°C for 6 hours, drain the water, and let it dry naturally at room temperature for 2 hours. 93%, water content up to 42%;
[0024] 2) Preheating of the steam explosion tank: open the steam valve to feed steam to preheat the steam explosion tank, and when the temperature of the steam explosion tank reaches 85°C, close the air valve;
[0025] 3) Pressure maintaining treatment: then put the pretreated corn into the preheated steam explosion tank, feed dry steam until the pressure in the steam explosion tank is 2.5MPa, adjust the flow of dry steam, and keep the pressure for 8 minutes;
[0026] 4) Steam explosion and material receiving: After the pressure is maintained, immediately open the discharge valve of the steam explosion tank, spray the corn steam ex...

[0029] Embodiment 2 The present invention carries out the step of steam explosion gelatinization treatment to raw grain wheat of liquor as follows:
[0030] 1) Raw material pretreatment: wash and soak the wheat in hot water at 95°C for 3 hours, drain the water, and let it dry naturally at room temperature for 3 hours. , with a water content of 45%;
[0031] 2) Preheating of the steam explosion tank: open the steam valve to feed steam to preheat the steam explosion tank, when the temperature of the steam explosion tank reaches 85°C, close the air valve;
[0032] 3) Pressure maintaining treatment: then put the pretreated wheat into the preheated steam explosion tank, feed dry steam until the pressure in the steam explosion tank is 2.0MPa, adjust the flow of dry steam, and keep the pressure for 5 minutes;
[0033] 4) Steam explosion and material receiving: After maintaining the pressure, immediately open the discharge valve of the steam explosion tank, spray the wheat steam expl...
Embodiment 3
[0036] Embodiment 3 The present invention carries out the step of steam explosion gelatinization treatment to raw grain rice of liquor as follows:
[0037] 1) Raw material pretreatment: wash and soak the rice in hot water at 90°C for 2 hours, drain the water, and let it dry naturally at room temperature for 3 hours, so that the grains can absorb water sufficiently and evenly, without hard core when pinched by hand, and the opening ratio reaches 93%, water content up to 40%;
[0038] 2) Preheating of the steam explosion tank: open the steam valve to feed steam to preheat the steam explosion tank, and when the temperature of the steam explosion tank reaches 80°C, close the air valve;
[0039] 3) Pressure maintaining treatment: put the pretreated rice into the preheated steam explosion tank, feed dry steam until the pressure inside the steam explosion tank is 1.5MPa, adjust the dry steam flow rate, and maintain the pressure for 7 minutes.
[0040] 4) Steam explosion and material...
