Embodiment 1

[0017] Disclosed is a primary curing process for high-density packaging of flue-cured tobacco leaves, which is applied to an upward-airflow curing barn.

[0018] The steps include the tobacco leaf yellowing period, the tobacco leaf withering period, the tobacco leaf color fixing period and the tobacco leaf drying tendon period.

[0019] A. Yellowing period: ① After the tobacco leaves are loaded into the furnace, the temperature is raised, and the dry bulb temperature is raised from the initial temperature to 39.0°C at a heating rate of 2.0°C / h, and the wet bulb temperature is adjusted to 37.0°C. The temperature is stabilized for 28 hours and baked to Tobacco leaves in the high-temperature layer turn yellow above 40%; ②At a heating rate of 2.0°C / h, raise the dry bulb temperature from 39.0°C to 44.0°C, adjust the wet bulb temperature to 37.0°C, keep the temperature stable for 28 hours, and roast the tobacco leaves in the whole furnace Until the blue veins and yellow slices are r...

Embodiment 2

[0031] The invention discloses a high-density packed primary curing process of flue-cured tobacco leaves, which is applied to a down-air flow curing barn.

[0032] The steps include the tobacco leaf yellowing period, the tobacco leaf withering period, the tobacco leaf color fixing period and the tobacco leaf drying tendon period.

[0033] A. Tobacco leaf yellowing period: ① After the tobacco leaves are loaded into the furnace, raise the temperature, and raise the dry bulb temperature from the initial temperature to 39.0°C at a heating rate of 2.0°C / h, adjust the wet bulb temperature to 37.0°C, stabilize the temperature for 32 hours, and roast Until the tobacco leaves in the high-temperature layer turn yellow above 40%; ②At a heating rate of 2.0°C / h, raise the dry bulb temperature from 39.0°C to 44.0°C, adjust the wet bulb temperature to 38.0°C, keep the temperature stable for 30 hours, and bake until the whole furnace Tobacco leaves reach blue veins and yellow slices.

Abstract

The invention belongs to the technical field of flue-cured tobacco modulation, and particularly relates to a primary curing process for high-density tobacco loading of flue-cured tobacco leaves. The process comprises a tobacco leaf yellowing stage, a tobacco leaf withering stage, a tobacco leaf color fixing stage and a tobacco leaf stem drying stage. The technical difficulty of the primary curing process is tobacco leaf moisture removal, and the tobacco leaf yellowing and drying are realized by adopting regulation and control means of low-humidity air moisture removal in a curing barn, moisture removal by temperature-controlled water and moisture removal by prolonging time at a key temperature point. The process has the advantages that the primary curing quality of flue-cured tobacco leaves is improved, the processing efficiency of flue-cured tobacco leaf primary curing equipment is improved, and the utilization rate of flue-cured tobacco leaf primary curing energy is increased.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco preparation, and in particular relates to a primary curing process for high-density packing of flue-cured tobacco leaves. Background technique [0002] For many years, the density of flue-cured tobacco leaves has been kept at a low level. Ordinary air-flow ascending barn or descending barn, the density of flue-cured tobacco leaves is 20-25kg / m 3 ;Air-flow ascending or air-flow descending intensive barn, the density of flue-cured tobacco leaves is 40-45kg / m 3 ;Large-box airflow ascending barn or descending barn, the density of flue-cured tobacco leaves is 80-120kg / m 3 . According to years of research by the author of the Yunnan Provincial Tobacco Agricultural Science Research Institute, the higher the density of the initial flue-cured tobacco leaves, the more fragrant and oily the flue-cured tobacco leaves will be. For every 4000-5000kg of fresh tobacco leaves in the initial curing p...
