A kind of tobacco puffing production process

Abstract

The invention discloses a tobacco puffing production technology. The technology comprises the following steps that S1, tobacco is placed in a microwave cavity of static microwave vacuum drying equipment; S2, steam is introduced for heating and humidifying; S3, microwave heating is conducted; S4, vacuumizing and puffing are conducted, wherein a vacuumizing device is started, and the vacuum pressurein a buffer tank is released into the microwave cavity, so that the vacuum pressure in the microwave cavity is rapidly reduced to be negative pressure; the vacuum pump continuously works, so that thevacuum pressure in the microwave cavity is continuously reduced till reaching a preset threshold value of the vacuum pressure; the vacuumizing device is shut down so that the vacuum pressure in the microwave cavity is maintained at the preset threshold value within a preset time range. According to the tobacco puffing production technology, the tobacco is preliminarily heated and humidified by introducing the steam, and the steam adheres to the surface of the tobacco, so that the effect of isolating oxygen is achieved; by means of steam introduction, the tobacco is effectively puffed, oxygenis further isolated, and the tobacco is prevented from being ignited and combusted.

Description

Technical field [0001] The invention relates to a tobacco puffing production process. Background technique [0002] Tobacco puffing technology currently involves relatively little microwave technology. Microwave technology is basically the mainstream of tunnel microwave. The advantage of tunnel microwave lies in the assembly line operation, which conforms to the assembly line operation process of modern production, but the disadvantages are: First, the lack of vacuum assistance The puffing of tobacco is purely dependent on the increase in temperature; the second is that there is no way to isolate oxygen, too high temperature will easily cause tobacco to ignite and burn, which is a relatively insurmountable shortcoming of tunnel microwave. Summary of the invention [0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a tobacco puffing production process, which through steam treatment, the tobacco is preliminarily heated and humidi...

AI Technical Summary

Problems solved by technology

[0002] Tobacco puffing technology is relatively less involved in microwave technology at present, and tunnel microwave is basically the mainstream when it comes to microwave technology. The advantage of tunnel microwave lies in the assembly line operation, which is in line with the modern production line operation process, but the disadvantages are: first, the lack of vacuum assistance , the puffing of tobacco purely depends on the increase of temperature; second, there is no way to isolate oxygen, and if the temperature is too high, it is easy to make the tobacco catch fire, which is a relatively difficult shortcoming of tunnel microwave
