Abstract

The invention relates to a microwave tobacco leaf fixation roasting and rewetting equipment, wherein, a microwave roasting device and a tobacco leaf rewetting box are arranged in the chasis, a vapor discharger is arranged on the microwave roasting device, the tobacco leaf rewetting box is provided with a vapor inlet, a tobacco leaf conveyer device is mounted in the chasis and penetrates through the microwave roasting device and the tobacco leaf rewetting box, preferably, the vapor inlet pipe is communicated with the outlet of the vapor discharger, the tobacco leaf conveyer device holds tobacco leaves with two bonded tobacco leaf conveyer belts, the microwave roasting device is a decimetric wave roasting device, a control device, two microwave leakage inhibiting devices arranged at two sides of the microwave roasting device and a condensate water recycling device arranged on the bottom of the tobacco leaf rewetting box are also provided. The invention also provides a related tobacco leaf fixation rewetting method, the microwave tobacco leaf fixation roasting and rewetting equipment in the invention is artful in design, simple in structure, fast in roasting, good in roasting quality and low in cost, is energy-saving and environment-friendly, occupies small area and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of tobacco leaf processing equipment, in particular to the technical field of tobacco leaf color fixing, curing and moisture regaining equipment, and specifically refers to a microwave tobacco leaf color fixing, baking and moisture regaining equipment and method thereof. Background technique [0002] At present, tobacco leaf drying rooms are mainly used for color fixing and curing of tobacco leaves. The tobacco leaf drying room uses coal or wood to heat the boiler, the boiler generates steam, and the steam circulates in the hot air pipe to heat the air; or directly heats the air through coal or wood, and then sends the hot air into the drying room through a fan, and then transfers the heat to Tobacco leaves, control a certain temperature to achieve the purpose of color fixing and curing of tobacco leaves. The main problems with this baking method are: [0003] ① Serious air pollution; the burning of coal a...

AI Technical Summary

Problems solved by technology

[0003] ① Serious air pollution; the burning of coal and firewood will cause serious pollution to the air and the environment;

[0004] ② High energy consumption and high operating costs; the heat conversion of coal and firewood and the heat dissipation in the air have determined the high energy consumption and high operating costs of tobacco leaf drying rooms;

[0005] ③Baking quality is poor and raw materials are wasted; due to long-term photosynthesis on the surface of tobacco leaves, a layer of wax layer is formed to prevent water loss, and the content of peroxidase in tobacco leaves increases; The wax layer is destroyed, and the water in the tobacco leaves is evaporated, so that the peroxidase in the tobacco leaves will produce a chemical reaction, and the tobacco leaves will turn black, which will affect the baking quality of the tobacco leaves; Tobacco leaves), so the thicker the wax layer, it is difficult to bake out qualified tobacco leaves, so in the actual tobacco leaf drying room, these tobacco leaves are basically thrown away, and there is no way to bake qualified tobacco leaves;

[0007] ⑤The baking time is long; it takes 90-120 hours to dry the tobacco leaves from about 75% moisture to 6-8% after putting the tobacco leaves in the drying room; the way of air heating and heat conduction has already determined the drying time of the drying room too long;

[0008] ⑥Large floor area; each drying room covers an area of ​​about 200 square meters, and 200 mu of tobacco leaves requires at least 10 drying rooms of 2,000 square meters;

[0009] ⑦ Can not achieve moisture resurgence of tobacco leaves; the tobacco leaf drying room can only achieve the effect of baking, and cannot realize the moisture resurgence process of tobacco leaves
