The need for management is mainly reflected in the fact that the structural contradictions of cigarettes in cigarette industry enterprises across the country are still prominent, and the problems of over-alcoholization and under-alcoholization are at the same time.

Existing, regulating the progress of tobacco aging has become a prominent issue for tobacco maintenance in industrial enterprises. At the same time, with the development of the tobacco industry and scientific and technological progress, information The introduction of information technology has promoted the informatization and refinement of the management of the incoming and outgoing of cigarettes; new technologies for controlling the aging of cigarettes have gradually been promoted in the industry Application. The anti-mold and insecticidal technologies of tobacco smoke also tend to be diversified and comprehensive.

GB/T 23220 aims to effectively solve the storage and storage problems of tobacco leaves (raw tobacco and sliced tobacco) and is intended to be composed of the following two parts:

---Part 1: Original smoke. The purpose is to put forward the necessary requirements based on the storage characteristics of raw tobacco before purchasing, purchasing station, tobacco leaf turnover and re-bake process.

The storage and custody requirements of each link are ensured through warehouse temperature and humidity control, storage tobacco pest control, in-warehouse inspection and maintenance to ensure that the original tobacco is stored Storage safety and quality of original cigarettes.

---Part 2: Smoke. The purpose is to regulate tobacco storage inspection, warehouse temperature and humidity control, alcoholization monitoring and regulation, and storage tobacco pests.
