Embodiment 1

[0039] (1) Clean the bottom of the stack, lay the cushion material, and lay two layers of PE-PA composite film (two layers of barrier film bottom film, both oxygen and moisture resistance, with a thickness of 11 wires) according to the size of the stack, of which two A pallet is placed between layers of PE-PA composite film;

[0040] (2) Carry out stacking of laminar tobacco leaves according to conventional stacking methods;

[0041] (3) according to the routine method, put the atmosphere regulating agent on the smoke pile, make the PE-PA composite film (thickness is 11 wires) into two film covers, first cover the smoke stack (inner layer film cover) with a film cover, Place a support device (carton) with a height of 20cm at the four corners and the center above the inner film cover on the top of the cigarette stack, and arrange a set of wireless automatic temperature monitoring equipment at the same time, and then use another film cover (outer film cover) Cover the cigarette...

Abstract

The invention provides a modified atmosphere storage method for promoting the accelerated alcoholization of the tobacco laminas in a cold region, and relates to the technical field of tobacco alcoholization. The method comprises the following steps of sealing a tobacco stack in which an atmosphere regulating agent is put by adopting two layers of barrier films, and filling an air layer with the thickness of 5-10cm between the two layers of barrier films; and when the temperature of the air layer is reduced to 15 DEG C or below and the duration time is longer than 8 h, replacing the air layer with the hot air with the temperature ranging from 30 DEG C to 35 DEG C. By adopting the air-conditioning sealing mode of a double-layer film cover, the temperature lowering speed of the tobacco stackcan be effectively decreased; in cooperation with a hot air exchange method, the temperature of the tobacco stack can be kept at a normal alcoholization temperature level, and the accelerated alcoholization of the tobacco laminas in the cold region is promoted; in addition, the problems of dew formation, runoff, tobacco leaf wetting and mildew caused by the direct contact with the sealing film ofthe tobacco stack due to the rapid cooling of the outside, can be thoroughly avoided.

Description

technical field [0001] The invention relates to the technical field of tobacco alcoholization, in particular to a controlled-atmosphere storage method for accelerating the alcoholization of tobacco in cold regions. Background technique [0002] Tobacco is one of the important economic crops in our country and an important processing raw material for the cigarette industry, with huge economic value. After the tobacco leaves are harvested and baked, in order to remove the green miscellaneous gas of the tobacco leaves, reduce the irritation of the taste, improve the aroma quality of the smoke, and reconcile the chemical components inside the tobacco leaves, it takes about 2 years of storage and aging time. According to incomplete statistics, about 80 million tons (1 load=50kg) of flue-cured tobacco leaves need to be stored in my country every year. [0003] Alcoholization of tobacco leaves is a very complicated comprehensive substance transformation process inside tobacco leav...
