Abstract

The invention discloses a grain processor control system which comprises a main circuit and a control circuit. The main circuit comprises a main power switch. The main power switch is connected with a switch NFB2, a metering power supply and a surge protector. The main circuit is provided with a switch NFB3, a switch NFB4, a switch NFB5, a switch NFB6 and a switch NFB7. The switch NFB3 is connected with exhaust fans through AC contactors; the switch NFB4 is connected with a feeding unit and a mesh-belt driving unit through frequency conversion and speed regulation; the switch NFB5 is connected with heating fans through AC contactors; the switch NFB6 is connected with heaters through AC contactors KM9-KM10; the switch NFB7 is connected with the primary side of a transformer TC; and the secondary side of the transformer TC is connected with the control circuit. The grain processor control system carries out control parameter adjusting according to change of grain processing conditions, and the operation is relatively simple.

Description

technical field [0001] The invention relates to the field of grain drying, in particular to a grain processor control system.
