Fruit/vegetable drying device and working method thereof

Abstract

The invention discloses a fruit / vegetable drying device and a working method thereof. With the fruit / vegetable drying device and the working method thereof, more fruit / vegetable windswept area is provided, the drying effect is better, the temperature at a baking area is uniform, and temperature jump can be avoided during the humidity elimination, so that the product quality is ensured. The fruit / vegetable drying device comprises a box body and a bidirectional circular drying system, wherein a baking area and a heating area are formed in the box body; a separation plate is arranged between the baking area and the heating area; an upper air vent is arranged at the top of the separation plate and a lower air vent is arranged at the bottom; a heating device and an air feeding device are arranged in the heating area; the bidirectional circular drying system comprises a counter-rotation circulating fan which is arranged in the heating area and located above the heating device; and the upper air vent, the counter-rotation circulating fan, the heating device and the lower air vent are communicated in sequence. The fruit / vegetable drying device provided by the invention is capable of ensuring that the temperature at each point in the baking area is more even.

Description

technical field [0001] The invention relates to the field of fruit and vegetable food processing, in particular to a fruit and vegetable drying device and a working method thereof. Background technique [0002] Fruit and vegetable drying technology is of great significance for the deep processing of agricultural products and increasing the added value of agricultural products. With the progress of society and the continuous improvement of people's living standards, people have higher and higher requirements for dried fruits and vegetables. For fruit and vegetable processing enterprises, these technical problems have not been effectively solved. Dried fruit, high efficiency, and can save labor and fuel equipment. [0003] The existing static drying of fruits and vegetables mainly includes earthen kiln drying and color steel drying room drying. Although earth kiln drying has a small investment cost, it has poor sanitation, uneven internal temperature, high labor intensity, p...

AI Technical Summary

Problems solved by technology

Although the case can realize automatic drying of fruits and vegetables, the fruits and vegetables on the automatic circulation rack "do not turn over" and are still exposed to wind on one side, resulting in poor drying results; in addition, the case fails to solve the sudden temperature change during dehumidification question
