Abstract

The invention relates to an efficient energy-saving type tobacco drying system. The drying system comprises a preheating drying box (2), an infrared drying roller (5), a heat pump circulation module,an air filter (17) and an air preheater (18), wherein the preheating drying box (2) is communicated with the infrared drying roller (5); the heat pump circulation module comprises a waste heat sourceevaporator (12), a compressor (13), a condenser (14), an expansion valve (15) and an air source evaporator (16) which are sequentially connected end to form a loop; and the air filter (17), the air preheater (18), the condenser (14) and the infrared drying roller (5) are sequentially connected. Compared with the prior art, convection and radiation heating drying treatment is carried out on tobaccoraw materials, heat is graded and fully utilized, and the efficient energy-saving type tobacco drying system has the advantages of being high in drying speed, efficient, capable of saving energy andthe like.

Description

technical field [0001] The invention belongs to the field of tobacco drying, and in particular relates to a high-efficiency and energy-saving tobacco drying system. Background technique [0002] Tobacco drying process is a very important tobacco raw material processing process. The purpose of drying treatment is to remove excess moisture in tobacco raw materials such as shredded leaves, shredded stems and rebaked leaves or shredded tobacco. In order to complete the drying process tasks of tobacco such as shredded leaves, shredded stems and rebaked leaves, the hot air system of the dryer generally uses air at a higher temperature to dry them, which consumes a lot of energy. At the same time, it is particularly important that tobacco is a heat-sensitive substance, and high temperature will destroy the taste of tobacco. Only by drying it at low temperature can the color, aroma, taste and texture of tobacco be better maintained. [0003] At present, tobacco drying equipment has...
