Vegetable dehydrator with elastic dialing mechanism

Abstract

The invention provides a vegetable dehydrator with an elastic dialing mechanism, comprising a tank body, transmission devices, conveying devices, radiation devices and guide rails, wherein a set of conveying device driven by the transmission devices is arranged in each layer of drying tank, each conveying chain plate is supported on each guide rail to form a groove-shaped material channel, each radiation device is arranged above each channel, material guiding grooves are arranged below the tail ends of the channels, the top of the tank body is provided with a material inlet, and the bottom of the tank body is provided with a material outlet. The vegetable dehydrator is characterized in that the conveying device in each layer is provided with an elastic dialing mechanism between two movable conveying chain wheels, both ends of a pin shaft provided with a rolling body are fixed on a U-shaped frame, one end of a telescopic rod, having a large diameter, is fixed at the outer side of the bottom of the U-shaped part, the small end of the telescopic rod, which is sleeved with a spring at the outside, is inserted in a small hole in the outer vertical wall of a support and is fixed through nuts, a spacing plate is clamped between the two nuts through the other nut, and one side face of the spacing plate is attached with the plane on the groove bottom of the support. The vegetable dehydrator can ensure the alternative conversion of each conveying chain plate and reliably turn over blanks.

Description

technical field [0001] The invention provides a vegetable dehydrator with an elastic dial mechanism, in particular a device for dehydrating and drying vegetables by using far infrared radiation and hot air. Background technique [0002] At present, the commonly used vegetable dehydration and drying form in China is hot air convection drying. In order to ensure the drying speed, the temperature of the hot air is generally higher, and the drying is carried out under normal pressure, so it is easy to cause a large loss of organic matter and nutrients such as Vc in vegetables due to oxidation. At the same time, too high temperature will also form a hard shell on the surface of the material, hindering the outward migration and evaporation of internal moisture. If the air temperature is lowered, the drying speed will be slowed down and the drying time will be longer. Not only can not guarantee product quality, but also greatly reduce production efficiency. Simultaneously, also ...

Problems solved by technology

Therefore, the swinging angle of the conveyor chain plate is not large enough, so that some conveyor chain plates still cannot be replaced alternately.
