Micro Negative Pressure Ethanol Production Equipment Maize / Corn Crushing Process

Brief introduction of corn crushing process

The feedstock corn is discharged from the bottom of the silo through an electric valve, conveyed to the crushing workshop by conveyor, and conveyed to the bucket scale by bucket elevator, then to remove impurities in the corn by sieve and stone removal machine. After cleaning, the corn goes into the buffer bin, and then through the iron removal variable frequency feeder to feed into the crusher uniformly. The corn is hit by hammer at a high speed, and qualified powder material enters into the negative pressure bin. The dust in the system is inhaled to the bag filter through a fan. The recovered dust returns to the negative pressure bin, and the clean air is discharged to the outdoor. In addition, the negative pressure bin is equipped with a material level detection alarm, the fan is equipped with a silencer. The whole system operates under the micro negative pressure, with low power consumption and no dust spillover in the working environment. The crushed powder is conveyed to the mixing system by the screw conveyor at the bottom of the negative pressure bin. The mixing system is controlled by computer and the ratio of powder material and water is controlled automatically.
