Tobacco shred fully-closed temperature-equalizing and humidity-equalizing method and equipment

Abstract

The invention discloses a tobacco shred fully-closed temperature-equalizing and humidity-equalizing method and equipment. The tobacco shred fully-closed temperature-equalizing and humidity-equalizingequipment comprises a main shaft, a humidifying system, a heating system, a discharging airlock and an equipment shell body, wherein a feeding port and a discharging port are formed in the two ends ofthe equipment shell body respectively, the feeding port is connected with a discharging port of an air-material separator of the airflow drying device, the discharging port is connected with the discharging airlock, the humidifying system is arranged at the end close to the feeding port, the heating system is arranged on the equipment shell body, the main shaft is arranged in the equipment shellbody, and loosening rollers are spirally distributed on the outer wall of the main shaft. The tobacco shreds are loosened firstly, then the tobacco shreds with substandard moisture are subjected to micro moisture regaining in a humidifying mode, and finally the tobacco shreds with too high moisture are rapidly evaporated in a mode of increasing the heating temperature, so that the phenomenon thatthe temperature and the humidity of the tobacco shreds are unbalanced after airflow drying is effectively avoided.

Description

technical field [0001] The invention belongs to the tobacco industry, and more specifically relates to a fully enclosed method and equipment for equalizing temperature and humidity after tobacco shreds are air-dried. Background technique [0002] After air-drying, the moisture content index of cut tobacco is generally 11.5-14%, the allowable deviation is ±0.5%, and the standard deviation is ≤0.17%; the temperature index is 55-75°C, and the allowable deviation is ±3°C. Under normal circumstances, the average temperature and humidity of cut tobacco after air drying can meet the target requirements, but local moisture fluctuations in cut tobacco often occur, and in severe cases, the moisture will exceed the process requirements, affecting the physical properties of cut tobacco and causing difficulties in downstream production line processing. [0003] The local moisture fluctuation of shredded tobacco is related to the characteristics of air-drying. The whole drying process of...
