Automatic turnover type hot air infrared fruit and vegetable drying device and method

Abstract

The invention discloses an automatic turnover type hot air infrared fruit and vegetable drying device. The device comprises a support, a conveying belt, a frame, a power motor, a drying cavity upper cover plate and a draught fan. Hot air is fed into a drying cavity through a hot air pipeline via an air inlet formed in the position of the frame of the conveying belt. The invention further discloses an automatic turnover type hot air infrared fruit and vegetable drying method. The water content of fruit and vegetable materials is calculated through the operating speed of the conveying belt, the base angle of the ridge-shaped drying cavity upper cover plate and the interval of infrared light pipes, the drying effect of the fruit and vegetable materials can be accurately controlled, the quality of dried fruits and vegetables is improved on the basis of improving quality research on the dried fruits and vegetables and reducing energy consumption, transportation is convenient, drying time is greatly shortened, production efficiency is improved, drying energy consumption is greatly reduced, energy is saved, and environment friendliness is achieved.

Description

technical field [0001] The invention relates to the field of fruit and vegetable drying, more specifically, the invention relates to an automatic tumbling hot air infrared fruit and vegetable drying device and an automatic tumbling hot air infrared fruit and vegetable drying method. Background technique [0002] Nowadays, fruits and vegetables are mostly vacuum-packed in order to be convenient and hygienic to eat, keep fresh, store and transport. Before packaging, the dirt on the surface of the fruits or vegetables is washed off, and after cleaning, they are dried with a fruit and vegetable dryer, and then packaged after drying. Otherwise, the shelf life of washed fruits or vegetables will be shortened and they will easily rot. The current fruit and vegetable dryer has slow drying speed, long assembly line and large floor space. In order to facilitate automatic tumbling during the conveying and drying process of fruits and vegetables, the fruit and vegetable conveying devic...

AI Technical Summary

Problems solved by technology

In order to facilitate automatic tumbling during the conveying and drying process of fruits and vegetables, the fruit and vegetable conveying devices of some fruit and vegetable dryers are set at an incline, and the fruits and vegetables at the input end are easy to pile up and convey forward. The input end of the machine rolls down to the output end, causing the fruits and vegetables to not be dried completely, and the dried fruits and vegetables are wetted. Workers need to pay attention to this situation at all times, and pick out the undried fruits and vegetables and re-dry them.

This kind of fruit and vegetable dryer not only increases the labor intensity of workers, but also has low work efficiency and poor drying effect.
