Description

Technical Field

[0001] The utility model relates to the technical field of crop processing, in particular to a crop processing drying machine. Background Art

[0002] Crop processing dryers are mechanical equipment specially used to remove moisture from crops (such as grains, fruits and vegetables, tea, etc.). This equipment evaporates the moisture in the crops by heating the air or using other drying methods, thereby achieving the purpose of drying, preservation and further processing.

[0003] For example, a Chinese patent discloses: an energy-saving intelligent crop dryer, patent number: CN210892521U, which converts physical signals into electrical signals through pressure strain gauges and sends them to the control panel. The control panel automatically controls the motor and the heater to work simultaneously. The active gear drives the two stirring pins to rotate through the two driven gears. At this time, the two stirring pins rotate in the opposite direction to the filter screen, stirring the crops. Compared with the existing dryers with multiple motors working at the same time, the dryer is driven by a single motor to dynamically stir the crops, with little loss of electricity resources and low cost of use. After the crops are placed in the dryer, the dryer can automatically start processing, with good intelligent performance and high work efficiency.
