Abstract

The invention discloses a baking method for tobaccos. The baking method for the tobaccos comprises the steps that fresh tobaccos are collected, the fresh tobaccos are placed in a container with multiple holes; the container with the fresh tobaccos is arranged in a yellowing device, the fresh tobaccos are fumigated and steamed through ripening agent, and temperature is controlled to enable the fresh tobaccos to be yellow; the tobaccos are put into a microwave dryer to be dried; the tobaccos are taken out of the microwave dryer; moisture absorption is conducted and the tobaccos are soft; the tobaccos are stored. By means of the baking method for the tobaccos, the fresh tobaccos are baked, pollution to environment can be reduced, manual investment is reduced, labor intensity is reduced, energy is saved, baking time is shortened, and tobacco quality is improved.

Description

The baking method of tobacco leaf

Technical field

The invention discloses a kind of baking method of tobacco leaf, belong to tobacco flue-curing applied technical field, is a kind of baking method that the fresh tobacco flue-curing of plucking from land for growing field crops is become to yellow dry tobacco leaf concretely.

Background technology

In leaf tobacco production, the fresh tobacco flue-curing of Production of Large Fields need to be made to dry tobacco leaf, so that later process processing.The method of known tobacco flue-curing is: fresh tobacco leaf plucks → fresh tobacco leaf is tied to dry on tobacco rod → hang into the drying room → variable color → fixation → heat drying of heating → go out drying room → moisture absorption weak → collection.

This traditional tobacco flue-curing method in use has following defect: the one, and while heating, need coal combustion or bavin that thermal source is provided, when coal combustion or bavin, except producing volume of smoke, in combustion process, also can form the harmful substance contaminated environment such as carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen oxide, organic compound and flue dust; The 2nd, the drying room thermal efficiency of heating is low, and outwards distributes the waste gas with uniform temperature by chimney, wastes energy; The 3rd, be manually tobacco leaf to tobacco rod, the amount of labour is large and waste of manpower resource; The 4th, tobacco leaf is to carry out in the drying room of 36 ℃～68 ℃ when entering drying room and going out drying room, and high-temperature operation is unfavorable for that operator is physically and mentally healthy; The 5th, the baking quality of tobacco leaf does not guarantee, waste is large, the loss of the tobacco leaf in bake process generally between 20～30%, the 6th, baking time is long, bright cigarette packs barn into having toasted, and often needs 90～140h, production efficiency is low; The 7th, equipment investment is many, floor space is excessive etc., and this existing tobacco flue-curing method has been unsuitable for environmental protection, energy-conservation, the needs of enhancing productivity, improving the quality of products.

Summary of the invention

The baking method that the object of this invention is to provide a kind of tobacco leaf, profit is baked fresh tobacco leaf in this way, and environmentally safe reduces and manually drops into, reduces labour intensity, saves the energy, greatly shortens baking time, improves quality of tobacco.

For realizing object of the present invention, taked following technical scheme:

A baking method for tobacco leaf, the baking method of described tobacco leaf is: fresh tobacco leaf plucks → is placed in porous container → the porous container that fills fresh tobacco leaf place urge stifling with ripener in yellow device, flavescence → enter microwave drier → go out microwave machine → moisture absorption weak → collect.

The present invention's ripener used is existing ethene on market, can be also ethephon (CEPHA)，2-(chloroethyl) phosphonic acid, and the concentration of ripener used is 1300～1500ppm.

The stifling time of the present invention is 6～8h, 30～32 ℃ of fumigation temperatures, flavescence time 30～35h, 38～49 ℃ of flavescence temperature.

The baking temperature of microwave dryer of the present invention is 60～67 ℃, and be 25～30min drying time.

Distinguishing feature of the present invention is that production technology is simple, and processing ease is convenient to grasp; The outstanding advantages that utilizes baking tobacco leaves of the present invention is environmentally safe, reduces and manually drops into, reduces labour intensity, saves the energy, greatly shortens baking time, improves quality of tobacco.
