Embodiment 1

[0024] Embodiment 1: Before starting production, the tobacco stems that meet the requirements of "raw material selection" (moisture balance, controlled at 8-14%, and no metal impurities) are prepared, and a heating furnace is used to evenly "heat the heat medium" to 100 ~200°C. The tobacco stems are mixed with heat medium and added to the equipment with microwave field. The tobacco stem processing device adopts a 10-160KW multi-mode cavity tunnel type microwave device (composed of a microwave source part, a microwave transmission part, a microwave cavity part, an air suction system, and a drag part). After 10-220 seconds of mixing and microwave action in the microwave device, the volume increases by 0.5-4 times, and the mixture is output from the outlet of the microwave device. And sent to the separator to separate the tobacco stems from the heat medium. After separation, the pretreated tobacco stems can be obtained with the advantages of low density, good elasticity, less wo...

Embodiment 2

[0025] Embodiment 2: Prepare the tobacco stems that meet the requirements of "raw material selection" (moisture balance, controlled at 8-14%, free of metal impurities) before starting production, and use the tobacco stem preheating device to heat it up to 90°C ±5. Use a heating furnace to evenly "heat the heat medium" to 100-200°C. The tobacco stems are mixed with heat medium and added to the equipment with microwave field. The tobacco stem processing device can use a 10-160KW multi-mode cavity rotary microwave device (consisting of a microwave source part, a microwave transmission part, a microwave cavity part, a microwave rotary cavity part, a suction air system, and a drag part). After 10-220 seconds of mixing and microwave action in the microwave device, the volume increases by 0.5-4 times, and the mixture is output from the outlet of the microwave device. And sent to the separator to separate the tobacco stems from the heat medium. After separation, the pretreated tobac...

Abstract

A technology for pre-processing the stems of tobacco leaves includes heating the low-loss granular solid microwave medium as thermal medium to 100-200 deg.c, mixing said stems with said thermal medium, heating in microwaven over for puffing the stems, and separating the tobacco stems from thermal medium. The pre-processed stems feature high loseness and elasticity, and good smell.

Description

Technical field: [0001] The invention relates to a tobacco preparation process, in particular to a pretreatment process for tobacco stems processed by microwave after mixing tobacco stems with microwave low-loss solid medium particle heat medium. technical background: [0002] Regarding the pretreatment of tobacco stems, the relevant method and equipment disclosed in CN 154218A, its essence is to replace the steamed stems in the traditional treatment process with the stem washing process, which is just a new transformation of the traditional process. It is difficult to improve the quality of aspects such as aroma. [0003] In foreign countries, in the pretreatment to improve the quality of tobacco stems, there is a method of using hydraulic pressure to change the texture of tobacco stems in tobacco. This method has been disclosed in US Patent 2344106 (1944.3.41). However, this method is difficult to operate in practice, and pressure devices and steam are required to prepar...
