Introduction

With the promotion and implementation of GB/T 23220-2008, the storage and custody of raw tobacco at tobacco farmers, purchasing sites and tobacco companies has become increasingly problematic.

highlight. Due to the many links involved, the time requirements for each link of raw cigarette storage are quite different from the storage and custody of sliced cigarettes. GB/T 23220-2008 is no longer suitable for the current storage and storage requirements of tobacco leaves. At the same time, with the development of the tobacco industry and scientific and technological progress, the storage and curing of tobacco leaves in terms of maintenance technology, the introduction of information technology can effectively promote the informatization and refinement of the management of raw cigarettes in and out of the warehouse; the maintenance of raw cigarettes has also changed from passive maintenance to Transitioning to active maintenance; the anti-mold and insecticide technology of tobacco leaves also tend to be ecological 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, 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.

Prevention and control, inspection and maintenance of cigarettes in the warehouse can standardize and standardize the storage and storage of cigarettes, and improve the alcoholization quality of cigarettes.
