Energy-saving environment-protecting type hot air vegetable drying device

Abstract

The invention discloses an energy-saving environment-protecting type hot air vegetable drying device which is mainly composed of a furnace body, a heat exchanger, a hot air supply pipe, a hot air return pipe, an exhaust fan, a hot air drying box, and a conveyor belt using a motor as power. More than two material turning mechanisms are distributed on the conveyor belt at intervals. By the adoption of the structural form, the energy-saving environment-protecting type hot air vegetable drying device has the advantages that the material turning mechanisms are further arranged, so that the vegetable drying effect is greatly improved; a steam tube bank is further arranged at the top of the hot air drying box so as to be favorable to drying vegetables, especially, the steam tube bank is connected with a blower so as to be favorable to dehumidification inside the drying box and enable the waste heat of steam to be fully utilized, and the largest advantage lies in that after being pumped into the furnace body, steam is favorable to combustion-supporting and improves the heat value inside the furnace body; a secondary heater exchanger is further arranged, and waste heat is absorbed by water, so that the waste heat can be fully utilized.

Description

technical field [0001] The invention relates to a vegetable drying device, in particular to an energy-saving and environment-friendly hot air vegetable drying device. Background technique [0002] The State Intellectual Property Office published the publication number CN202873749U on April 17, 2013, and the patent name is a utility model patent for a drying device for dehydrated vegetables. There is a diffuser on the top of the air drying high-pressure box, and the material with high moisture content is carried by the hot air along the wind pressure and enters the dehumidification splitter until the moisture content reaches the set value, and the wind pressure is reduced. This reciprocating drying method overcomes the problem of non-uniform moisture content in previous drying equipment and can work continuously. The air is conveyed through the drying oven by the high-temperature and high-speed superheated air, and the speed is always lower than the air velocity when runnin...
