Arch Bridge Ladder Conveyor Tunnel Dryer

Abstract

The invention discloses an arch bridge ladder conveying type tunnel drying machine. The arch bridge ladder conveying type tunnel drying machine comprises a drying box. One end of the drying box is a feeding port, the other end of the drying box is a discharging port, a conveying belt is arranged between the feeding port and the discharging port, power rolling wheels are arranged at the two ends ofthe conveying belt correspondingly, and the power rolling wheels are connected with a variable frequency motor through a reduction box; and the conveying belt is a transportation screen mesh made ofstainless steel, the hole diameters of the transportation screen mesh are 0.1-1.0 cm, supporting rolling wheels are arranged on the lower portions of the transportation screen mesh, and the transportation screen mesh is an arc bridge type ladder conveying belt. According to the arch bridge ladder conveying type tunnel drying machine, automatic turnover can be conducted on materials containing water, piece-shaped materials, block-shaped materials, strip-shaped materials, spoon-shaped materials and powder prone to being blocked in the drying process or irregular materials through the arch bridgeladder conveying type tunnel drying machine, material drying is more even through surrounding hot wind on the lower portion of the drying box, and waste products are obviously reduced.

Description

technical field [0001] The invention relates to a material drying machine, in particular to an arch bridge ladder conveying tunnel drying machine. Background technique [0002] Tunnel dryers are widely used in the agricultural product drying industry, both commercially available and self-made. Nie Baojun and Zhang Zhongxin developed the "tunnel dryer parameter energy-saving optimization" (Food Science and Technology, 2010, Volume 25, Issue 6). The drying medium is hot air. The equipment is composed of fan, heater, tunnel section, material trolley, bracket and so on. Utility model patent CN201520581252.8 "a kind of konjac drying machine". In order to avoid the sticking of konjac pieces, a soft rubber sheet is installed on the lower part of the scraper to scrape the sticky konjac pieces. Rubber products emit toxic and harmful chemical substances during drying and heating, and these chemical substances are absorbed by dried konjac pieces, resulting in food contamination. Inv...

Problems solved by technology

[0003] The purpose of the present invention is to provide an arch bridge ladder conveying tunnel dryer, which overcomes the defects of the prior art and solves the problem that the existing conveyer transports materials on a plane, the materials move in translation on the belt, and the materials cannot be turned over and changed, thus resulting in uneven drying.
