Problems solved by technology

But this technical scheme still has the following two defects: one, in order to obtain the required expansion and pressurization treatment requirements, its equipment adopts two-stage treatment, and a steam valve is set between its first treatment section and the second treatment section, and its The first superheated steam section must be emptied regularly, so the treatment process of the tobacco stems is intermittent. To maintain the continuity of the treatment, the enterprise must purchase more than two sets of the same equipment; the regular emptying of the first superheated steam section also leads to A large amount of steam energy is wasted; the second is that the equipment adopts a sharp-hole nozzle arranged on the outlet pipe of the second superheated steam section to realize the rapid depressurization of the tobacco stem steam mixture and obtain the expansion effect of the tobacco stem. Therefore, the equipment usually It can only process short stems below 30mm, otherwise it is very easy to block the small hole of the nozzle above, which makes it necessary to sieve the tobacco stems before the corresponding expansion process, and re-cut the long stems, so when using this equipment When tobacco stem puffing is performed, the corresponding pre-processing procedures are relatively complicated

Abstract

The present invention discloses one kind of continuous tobacco stem expanding saturated or overheat steam apparatus and its tobacco stem treating process before cutting shreds. The online tobacco stem expanding apparatus includes a feeding bin; a discharging bin; and a pressure treating bin with an inside auger delivery device, several steam nozzles and pneumatic steam locks separately set in the inlet and the outlet. The apparatus has no need of evacuating steam inside the pressure treating bin before feeding material, can realize the online continuous treatment of tobacco stem material, and has high treating efficiency and low steam consumption. The tobacco stem treating process before cutting shreds with the said apparatus is simple and has no step of cutting the screened long tobacco stem.

Description

technical field [0001] The invention relates to an online expansion device for tobacco stems, in particular to a device for expanding treatment of tobacco stems with saturated or superheated steam. [0002] The present invention also relates to a method for pre-cutting tobacco stems by using the online tobacco stem expansion equipment. Background technique [0003] For tobacco manufacturing enterprises, improving the treatment effect of tobacco stems before shredding includes making the tobacco stems have uniform and appropriate cutting humidity to facilitate the cutting of tobacco stems, and making the tobacco stems have sufficient expansion to improve the filling of tobacco products. It is an important way for enterprises to reduce production costs. At the same time, obtaining shredded tobacco stems with high expansion degree is also a main way to manufacture safe tobacco products with low tar content. [0004] Generally, in order to achieve the above objectives, tobacco...
