Drying device for dehydrated vegetables

Abstract

The present invention discloses a drying device for dehydrated vegetables. The device is characterized by comprising a heat exchange box, an air blower, an air separation chamber, a drying box and anexhaust fan; the air blower, the air separation chamber and the drying box are sequentially connected to one side of the heat exchange box along the flow direction of steam; a plurality of receiving nets used for stacking materials are movably and horizontally inserted in the drying box; an air inlet pipe is arranged between every two receiving nets; the air inlet pipe connects the air separationchamber with the drying box; the upper end face of the drying box is provided with the exhaust fan; and the exhaust fan communicates with the other side of the heat exchange box through an exhaust pipe. A drying cylinder is divided into a multi-layer structure, an air inlet pipe is arranged between every two layers, high-temperature gas drying is carried out on each layer of material, so that theproblem of uneven drying is effectively avoided, and the drying efficiency and the drying quality can be greatly improved.

Description

technical field [0001] The invention relates to the field of processing equipment for dehydrated vegetables, in particular to a drying device for dehydrated vegetables. Background technique [0002] Dehydrated vegetables, also known as rehydrated vegetables, are a kind of dried vegetables made by washing and drying fresh vegetables to remove most of the water in the vegetables. The original color and nutrients of the vegetables basically remain unchanged, which is easy to use. Storage and transportation, and can effectively adjust the off-peak season of vegetable production. [0003] In the drying part of the dehydrated vegetable production line, most drying devices use high-temperature gas to take away the moisture in the vegetables to achieve the purpose of drying. However, these vegetables are often directly stacked in the drying box when drying, and the water in the vegetables can only be slowly drained by high-temperature gas, the work efficiency is extremely low, and ...

AI Technical Summary

Problems solved by technology

However, these vegetables are often directly stacked in the drying box when drying, and the water in the vegetables can only be slowly drained by high-temperature gas, the work efficiency is extremely low, and the outer layer of vegetables will be seriously dehydrated. The phenomenon of drying greatly affects the taste and preservation of dehydrated vegetables
