Vegetable dehydrator with material clearing devices on lower portion

Abstract

The invention provides a vegetable dehydrator with material clearing devices on the lower portion. The vegetable dehydrator is characterized in that a group of conveying devices driven by a transmission device to operate is arranged in each layer of a box body, chains of the conveying device extend inwards to form pin shafts at intervals, chain plates are hung on the pin shafts formed by inward extension of the chains through hanging holes at two ends, and baffles are supported on a guide track to form groove-shaped material channels. An infrared radiation device is arranged above each channel, a material guiding groove is formed in the lower portion of the tail end of each channel, an air inducing port is formed in the upper portion of the lateral wall of each layer of the box body and connected with a fan through an air inducing pipe, poking levers are evenly fixed on a chain wheel end face of each conveying device at the position below each transmission device, a limit rod is arranged between each chain wheel and the inner wall of the box body, an elastic poking plate mechanism is arranged at the chain wheel position of each conveying device at the position below a feeding port, each conveying device is provided with the material clearing devices arranged below an upper groove-shaped material channel and a lower groove-shaped material channel below the feeding port, the feeding port is arranged in the top of the box body, and a discharging port is arranged in the bottom of the box body. The vegetable dehydrator is thorough in material clearing and reliable in working.

Description

technical field [0001] The invention provides a vegetable dehydrator for cleaning materials from below, in particular to a device for dehydrating and drying vegetables by heating with infrared radiation. Background technique [0002] At present, the commonly used vegetable dehydration and drying form in China is hot air drying. In order to ensure the drying speed, the temperature of the hot air is generally relatively high, and in addition, the drying is carried out under normal pressure. Due to oxidation, it is easy to cause a large loss of nutrients such as organic matter and Vc in the vegetables, and the color of the dried vegetables will deteriorate. The loss of nutrients is serious. , the grade is lowered. Therefore, the dried vegetables obtained by drying by means of hot air convection can no longer meet people's quality requirements for dehydrated vegetables, and its market competitiveness is also getting worse. [0003] In view of the above problems, people think t...

AI Technical Summary

Problems solved by technology

However, although the vegetable dehydrator involved in the above-mentioned patent adopts the 2-time blanking technology to achieve clean and thorough blanking as much as possible, due to the strong adhesion between the vegetables and the chain plate after absorbing heat, some materials are stuck. On the chain plate, resulting in insufficient blanking

Vegetables left on the chain plate are burnt due to repeated drying, and bacteria are easy to breed, which seriously affects the dry quality of vegetables. Therefore, we have applied for a national invention patent "vegetable dehydrator with flip plate cleaning material", application number for 201310358514.X

However, through further experiments, it was found that although the patented technologies involved in ZL201110066663.X and 201310358514.X can remove part of the sticky material, the entire cleaning process requires the chain plate to be kept in a horizontal state after blanking

If you want to clean the chain plate completely, it is required that the chain plate should maintain a certain angle during the blanking process or remain in a horizontal state after blanking, at least running the width of one piece of chain plate, which not only makes the length of the trough-shaped material channel relatively reduced , and it is too difficult to keep the angle constant, so the cleaning effect is not ideal
