Fruit and vegetable drying machine

Abstract

The invention discloses a fruit and vegetable drying machine, and belongs to the field of drying of agriculture products. The fruit and vegetable drying machine comprises a drying chamber, wherein a feeding opening is formed in the top of the drying chamber; a distributing device is arranged at the upper part of the inner part of the drying chamber, corresponding to the feeding opening, and can beused for uniformly tiling materials on a plurality of feeding turning plates which are sequentially arrayed; a lifting supporting mechanism is arranged on the lower side of each feeding turning plate, and is in transmission connection with a lifting driving device; a discharging channel allowing the materials to fall is reserved on each lifting supporting mechanism; at least one layer of drying supporting layers which are vertically arrayed at intervals are arranged under the distributing device, in the drying chamber; each drying supporting layer comprises a plurality of drying turning plates which are sequentially arrayed; each drying turning plate is rotatably connected to the drying chamber by the corresponding drying rotating shafts; each set of the drying rotating shafts are in transmission connection with the corresponding overturning driving device; and a discharging mechanism is arranged at the bottom of the drying chamber. According to the fruit and vegetable drying machinedisclosed by the invention, the overall length of the turning plates can be opened, and materials on each layer are safely transmitted level by level, so that the situation that the materials are sufficiently in contact with thermal wind is guaranteed, and the materials are sufficiently dried.

Description

technical field [0001] The invention belongs to the field of drying agricultural products, in particular to a fruit and vegetable drying machine. Background technique [0002] The existing drying of fruits and vegetables mainly relies on natural drying, kiln drying and other methods, and the more advanced ones use tunnel dryers with drying cars or belt dryers. The drying method of natural drying has long working hours and high labor intensity, and it is difficult to realize automation; the tunnel dryer occupies a large area, and heat is easily lost between adjacent temperature sections, so it is difficult to accurately control the temperature of each temperature range , affecting the effect of segmented temperature and humidity control. [0003] In the prior art, there is a self-circulating multi-layer flap dryer and a self-circulating segmental drying method, its patent application number: 201010253258.4; application date: 2010.08.09; announcement number: CN 101972032 B; a...

AI Technical Summary

Problems solved by technology

[0004] When working, the multi-layer flap conveying device is used in conjunction with the hoist, and the material plays a role of turning during the self-circulation process, which makes the contact frequency of the material and the hot air higher and improves the drying effect. The disadvantage is that the material can only It falls from the upper layer of the flap conveying device to the lower layer through the upper blanking section, and can only fall from the upper flap conveying device to the lower flap conveying device through the lower blanking section. The area of ​​the upper and lower blanking sections is small, Only part of the material is discharged, and there is a lot of material on each layer of the flap conveying device that cannot be moved, resulting in uneven discharge, and the material cannot evenly fall on the next layer of the flap conveying device, and finally the material cannot be fully contacted with the hot air. , most of the materials cannot be fully dried, which affects the drying effect of the materials; it occupies a large area and wastes space; the structure is too complicated and the manufacturing cost is high
