The invention discloses a raw material cleaning device for pectin processing. The raw material cleaning device comprises a first air pipe, a first air drying opening, a first motor, a fixed plate, a threaded rod, a second air drying opening, a baffle, a rubber seal block, a pull rod, a second air pipe, a connection rod, a recovery box, a strainer, a sleeve shaft, a fixed rod, a partition, a waterpump, a water injection opening, an outer frame, an inner frame, a brush plate, a connection plate, a cleaning box, a second motor, a fan, a support plate and a box door. The inner frame rotates alongwith the fixed rod, and raw materials can be washed. The threaded rod can adjust the height of the brush block, the surfaces of the raw materials are washed in a brushed mode, and cleaning strength and efficiency are improved. The connection rod can support the bottom of the outer frame, stable rotation of the inner frame is kept, the recovery box can filter and recover wastewater after primary cleaning, and water flow circulation between the recovery box and the cleaning box can be achieved. The first air drying opening and the second air drying opening can conduct air drying on the top andtwo sides of the inner frame, the contact area of the raw materials and air is increased, air drying speed is increased, and water can be prevented from entering the second air drying opening throughthe baffle and the rubber seal block.
