Technical Field
[0001] The utility model relates to the field of peanut processing devices, in particular to a drying device used for peanut production. Background Art
[0002] Peanuts are a widely grown crop with important economic value worldwide. In the production of boiled peanuts, drying is one of the key processing steps, which directly affects the quality and storage life of peanuts.
[0003] Currently, natural air drying and air-drying are mainly used to clean and dry the water stains on the peanut skin, or a drying machine is used to dry the water stains on the surface of the peanuts. However, the efficiency of natural air drying is low, and the peanuts are not heated evenly during the drying process of the existing drying machines, which can easily cause some peanuts to be over-dried or over-wet. Therefore, a drying device for peanut production is needed to solve the problems of low drying efficiency and uneven drying. Utility Model Content
[0004] The invention purpose of the utility model is to provide a drying device for peanut production in view of the problems of low efficiency and uneven drying of existing peanuts, wherein a pre-dehydration mechanism is provided to pre-dehydrate wet peanuts, and then the peanuts are passed through the drying mechanism to further remove the remaining water stains on the peanuts. A conveyor belt and a peanut turning component are provided in the dryer, and the problems of low efficiency and uneven drying of peanuts are solved through the above design.

The screen can vibrate and remove excess water stains on the surface of the peanuts. The peanuts pass through the discharge end of the pre-dehydration mechanism and enter the conveyor belt in the drying mechanism.

The support rods provide support for the heating plate.
[0012] As a preferred solution of the utility model, the screen is designed with an inclined structure, and springs are provided at both ends of the screen. When wet peanuts are put onto the screen, the inclined screen and the vibrating member enable the peanuts to automatically move to the lower part of the screen and be sent to the conveyor belt, and the springs provide support and buffering for the screen.
[0013] As a preferred solution of the present utility model, the vibrating member is a vibration motor.
[0014] As a preferred solution of the utility model, a water outlet is provided at the bottom of the pre-draining mechanism, which is used to release the water from the wet peanuts under the screen, and a space is left below the water outlet to place a water basin or an external pipe for drainage.
