Tumble dryer for fruit and vegetable drying

Abstract

The invention relates to an overturn type drying machine used for drying vegetables and fruits. The overturn type drying machine comprises a box body with an open top end, a clamping screen mesh, an elevating cover and a return air duct with a moisture exhausting device, wherein a hot-air blower is fixedly connected to the side wall of the box body; the hot air outlet of the hot-air blower is communicated with the inner cavity of the box body; a plurality of driving gears which are arranged at equal intervals and a plurality of supporting shaft rollers which are arranged at equal intervals are arranged on the top edge of each of the front side wall and the rear side wall of the box body; the clamping screen mesh is used for tightly clamping raw materials and comprises two screen mesh plates which are connected in a hinged manner on one side edges and connected by adopting a lock buckle on the other sides; a rotating shaft is arranged in the middle of each of the front side edge and the rear side edge of one of the screen mesh plates; a driven gear is arranged at the end part of the rotating shaft on one of the two sides; the elevating cover is arranged on the box body in a buckling manner; a funnel with a first axial flow fan is arranged at the top of the elevating cover; the upper end of the return air duct is connected to the funnel by adopting a hose, and the lower end of the return air duct is connected to a return air inlet formed in the side wall of the box body.

Description

technical field [0001] The invention belongs to the technical field of food processing equipment, and in particular relates to a tumble dryer for drying vegetables and fruits. Background technique [0002] In the food processing industry, it usually involves the drying and drying of food raw materials, such as deep drying of fruits and vegetables and dried fruits, etc. The above drying process is generally carried out on a dryer. Existing dryers are generally mesh belt dryers, and the raw materials to be dried are transported forward through the conveying mesh belt, and then dried through the hot air area. The dryer with the above-mentioned structure has the following defects: in the process of moving raw materials, the drying is insufficient due to the lack of turning effect, and when deep drying processing is required, multiple dryings have to be carried out, which reduces the processing efficiency and is more expensive. energy.
