Fruit and vegetable drying device

Abstract

The invention relates to a fruit and vegetable drying device. The drying device comprises a rack, wherein the outside of the rack is wrapped with metal plates to form a sealing box body; a hopper is arranged at the top of the head end of the box body; a transverse conveyor mesh belt is arranged inside the box body; the head end of the conveyor mesh belt is positioned below a discharge opening of the hopper, and the tail end of the conveyor mesh belt penetrates out of an outlet formed in the side wall of the tail end of the conveyor mesh belt; a speed reducer used for driving the conveyor mesh belt is arranged on the rack; a gas collecting hood is arranged on the top wall of the box body; a chimney provided with a first axial fan is arranged at the middle part of the gas collecting hood; a plurality of hot-air blowers are arranged on the front side wall or the rear side wall of the box body; the hot-air outlets of the hot-air blowers are communicated to an inner cavity of the box body; a material receiving box is arranged blow the tail end of the conveyor mesh belt on the side wall of the tail end of the box body; a return air duct is arranged between an outlet of the chimney and a return air inlet in the box body; a moisture removing device is arranged inside the return air duct; material mixing devices used for mixing and stirring fruit and vegetable raw materials are arranged at the upper part of the conveyor mesh belt between the front side wall and the rear side wall of the box body.

Description

technical field [0001] The invention belongs to the technical field of food processing equipment, in particular to a vegetable and fruit drying equipment. Background technique [0002] In the field of food processing, it usually involves the drying processing of vegetable and fruit raw materials, and the above drying processing process is usually carried out on a dryer. Existing vegetable and fruit dryers are generally mesh belt dryers. The strips of vegetables and fruits are transported forward along the mesh belt and pass through the area covered with circulating hot air. The moisture in the raw materials of vegetables and fruits is taken away and dried. The vegetable and fruit dryer with the above structure has the following defects: there is no turning effect during the conveying process of the vegetable and fruit raw materials, which leads to insufficient drying of the vegetable and fruit raw materials; the low heat energy utilization rate results in high energy consump...
