Unprocessed grains all come from the main producing areas of high-quality ecological grains. The complete set of grain storage equipment is the automatic ecological granary of 100,000 tons introduced from the American GSI company at a great expense of the Shede spirits. This equipment adopts the method of low temperature physical storage for automatic temperature control, dehumidification, purification and turnover. The temperature in the storage process of grain is regulated by the grain refrigerator, which keeps below 15℃ all the year round to ensure that the grain is free from insects, mildew and deterioration.
