Embodiment 1

[0037] Such as Figure 1-14 The shown tunnel-type fruit and vegetable drying room includes a drying room set on a base 1. In order to reduce heat loss, an insulation layer is also provided on the base 1, and a driving drying car 6 is provided on the base 1 to enter and exit. The driving mechanism of the drying chamber. The drying chamber includes an outer box body 2 and an inner box body 8. There is a circulating air duct 10 between the outer box body 2 and the inner box body 8. The circulating air duct 10 is located in the inner box body 8. A number of circulating fans 18 are provided on the top, and a heater 17 is provided corresponding to the circulating fan 18. The circulating fan 18 is arranged in the center of the top of the inner box 8, and the heater 17 is arranged in the wind front passage or the wind rear passage of the circulating fan 18 One end of the circulating fan 18 faces the inner box 8, and the other end of the circulating fan 18 is provided with a V-shaped ai...

Embodiment 2

[0041] The difference from the method in Example 1 is that the switchable door 9 is always open, and the driving mechanism gradually pushes into the drying cart 6 containing the materials to be dried, and at the same time, the corresponding dried and cooled drying cart is pushed out 6.

Embodiment 3

[0043] Such as Figure 15 The difference between the tunnel-type fruit and vegetable drying room shown in Embodiment 1 is that the circulating air outlet 15 is rectangular.

[0044] The present invention is not limited to the above-mentioned embodiments. It should be noted that the humid air exhaust device 5 corresponding to each unit section can respectively exhaust the humid air, or can be combined to exhaust the drying chamber, and the exhaust steam assembly connected to the heater 17 23. Excess steam can be discharged separately, or the excess steam can be collected and discharged out of the drying room. In addition, the realization of drying fruits and vegetables is not limited to using the steam pipe 22 to input the dried heat into the drying room to dry the fruits and vegetables. Use other heat-conducting oil circuits to dry fruits and vegetables. The air curtain fan can also be completely or partially replaced by an isolation door. Heating and humidity control devices can ...

Abstract

The invention provides a tunnel type fruit and vegetable drying chamber and a fruit and vegetable drying method in the technical field of drying. The tunnel type fruit and vegetable drying chamber comprises a drying chamber arranged on a base, wherein driving mechanisms used for driving a drying vehicle to enter and come out of the drying chamber are arranged on the base; the drying chamber comprises an outer box body and an inner box body; a circulating air duct is reserved between the outer box body and the inner box body; a plurality of circulating fans are arranged in the positions, at the top of the inner box body, inside the circulating air duct; heaters are arranged corresponding to the circulating fans; a plurality of circulating air holes are formed in the side wall of the inner box body; an air supplementation pipe is arranged on the inner box body to communicate with the external air; an air supplementation valve is arranged on the air supplementation pipe; a wet air discharge device is further arranged on the inner box body or the outer box body; the integral driving mechanisms are positioned inside the drying chamber; and openable and closable doors are arranged at the two ends of the drying chamber. According to the tunnel type fruit and vegetable drying chamber, the thermal loss is low, energy is saved, the fruit and vegetable drying degree is uniform, and the quality of dried fruits and vegetables is good.

Description

Technical field [0001] The invention relates to a drying room, in particular to a device for drying fruits and vegetables. Background technique [0002] The prior art dryers include belt dryers, tunnel dryers, drum dryers, etc., and tunnel dryers have a reasonable structure, low energy consumption, high output, and convenient operation. Fruits and vegetables such as red dates, shiitake mushrooms, wolfberry, and peppers are widely used. [0003] Commonly used tunnel dryers include a drying box set on the base. The base is equipped with a driving mechanism that drives the drying car in and out of the drying box. Fruits and vegetables are dried in the drying box. The hot air circulation is not good, resulting in a large temperature difference, and the temperature zone can not be separated; the drive mechanism usually adopts a chain rail structure, and the chain rail extends outside the drying box, resulting in a complete seal even if a rolling door is provided, and the heat loss is r...
