Intensive curing barn baking process for airflow alternate-operation flue-cured tobacco

Abstract

The invention relates to an intensive curing barn baking process for airflow alternate-operation flue-cured tobacco, belonging to the technical field of flue-cured tobacco preparation process. The intensive curing barn baking process for airflow alternate-operation flue-cured tobacco is the improvement on the existing intensive curing barn baking process. The improvement point is characterized inthat interval time for the alternate operation of airflow rise and airflow descending is as follows: in the low-temperature humidifying and yellowing stage: two airflow operation modes are provided, the time interval is 0.50 hour, and alternation is carried out once; in the stable-temperature dehumidifying and withering stage: two airflow operation modes are provided, the time interval is 0.50 hour, and alternation is carried out once; in the ventilating, dewatering and leaf-drying stage: two airflow operation modes are provided, the time interval is 0.75 hour, and alternation is carried out once; and in the temperature and moisture controlling and tendon drying stage: two airflow operation modes are provided, the time interval is 1.00 hour, and alternation is carried out once. Other baking operation technologies of the process are same with the conventional baking process. The intensive curing barn baking process can obviously improve the baking property of the tobacco loading chamber of the intensive curing barn, improve tobacco leaf baking quality, and improve the safety for baking the tobacco leaf. The intensive curing barn baking process is suitable for intensive baking underdifferent ecological environment conditions in the tobacco area in China.

Description

Technical field: [0001] The invention relates to a flue-cured-tobacco-intensive curing barn baking process with alternating airflow operation, and belongs to the technical field of flue-cured tobacco modulation technology. Background technique: [0002] The introduction and planting of flue-cured tobacco in China has experienced various forms in the past 100 years, and the reform of the baking process. For example: two-stage baking process, multi-stage baking process, "two long and one short" baking process, three-stage baking process, ordinary baking room baking process, intensive baking room baking process, etc.; In a specific historical period, under a specific economic basis, combined with a specific type of baking room, different content and different forms of baking techniques have been produced. [0003] As far as the world is concerned, in the hundreds of years of flue-cured tobacco production practice, there are a variety of baking techniques. For example: the low...

Problems solved by technology

Looking at these baking processes, they are all based on a single airflow operation mode, and do not involve two or more airflow operation modes. Therefore, the baking process of flue-cured tobacco-intensive barns with alternating airflow operation is an innovation. Through document retrieval, there is no public report identical with the present invention both at home and abroad
