High-efficiency thermal wind tunnel circulating fruit and vegetable drying machine

Abstract

The invention discloses a high-efficiency thermal wind tunnel circulating fruit and vegetable drying machine. The structure of the high-efficiency thermal wind tunnel circulating fruit and vegetable drying machine comprises a machine frame, a working table, a conveying system, a moisture discharging opening, wind blowing units, a motor, a circulating wind channel, a wind equalizing machine and a wind capacity adjusting system, wherein the conveying system is laterally and movably connected to a middle and upper part of an inner cavity of the machine frame and a middle and upper part of an inner cavity of the working table; the wind blowing units are uniformly distributed on the lower end surface of the conveying system at an equal distance; the circulating wind channel is laterally and fixedly connected to the undermost part of the inner cavity of the machine frame and the undermost part of the inner cavity of the working table; and the wind capacity adjusting system is movably connected to the middle and lower part of the inner cavity of the machine frame and the middle and lower part of the inner cavity of the working table. According to the high-efficiency thermal wind tunnel circulating fruit and vegetable drying machine disclosed by the invention, in the course of performing thermal wind tunnel circulating drying operation on fruits and vegetables, certain humidity sensingoperation can be performed on the fruits and vegetables which leave the conveying system of the equipment soon, and certain wind capacity adjusting treatment can be performed when the humidity is toohigh, so that the situation that the drying effect can achieve the expectation is guaranteed, the situation that the subsequent fruit and vegetable processing work is smoothly performed is also guaranteed, and the practical properties of the equipment are effectively improved.

Description

technical field [0001] The invention relates to a high-efficiency hot air tunnel circulation fruit and vegetable dryer, which belongs to the technical field of fruit and vegetable dryer manufacturing. Background technique [0002] At present, the drying method used in the processing of fruits and vegetables and agricultural products is usually boiler steam drying. This drying method is easy to cause the boiler temperature to be unstable because of the unstable air pressure in the boiler. To meet the constant temperature, it often needs to rely on manual operation. , and the hot and humid air in the drying room is difficult to deal with and cannot be recycled, which will affect the drying quality and drying time. Traditional boiler steam drying uses electric heating or combustion heating, which wastes a lot of energy. Some fruits and vegetables are generally dried directly in the sun, which is greatly affected by the weather and is easy to deteriorate; using combustion to he...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a highly efficient hot air tunnel circulation fruit and vegetable dryer to solve the problem of low cost and low energy consumption in the process of hot air tunnel circulation drying of fruits and vegetables in the prior art. It is low in size and small in size, but it cannot perform a certain humidity sensing operation on the fruits and vegetables that are about to leave the equipment conveying system and perform a certain air volume adjustment process when the humidity is too high, which may cause the drying effect to fail to meet expectations. The problem of insufficient practical performance
