Embodiment approach

[0026] Taking the tobacco stem as the expansion processing object, the preferred embodiment of the present invention is as follows:

[0027] 1. Remoisturize the tobacco stems, and control the moisture content at 22%-25%.

[0028] 2. The rehydrated tobacco stems are blasted with superheated steam, the pressure temperature of the superheated steam is controlled between 180 and 220 degrees, and the inlet pressure is controlled at 8-10 bar, preferably 9.5 bar.

[0029] 3. Carry out moisture adjustment treatment on the expanded tobacco stems, and control the moisture content at 11%-13% to ensure no agglomeration, so as to facilitate the later screening and shredding treatment.

[0030] 4. The tobacco stems after moisture adjustment are screened, and cut into filamentous stems by a double-roller slitting machine.

[0031] Such as figure 1 As shown, as a preferred solution, the equipment system of the present invention includes a dampening barrel 1, a conveyor belt 2, a piston typ...

Abstract

The invention provides a method and a device for preparing cut expanded plant stems. Threadlike expanded plant stems can be obtained by means of the method and the device. The method comprises the steps of performing moisture regaining treatment to plant stems and controlling moisture content to be 16%-28%; performing exploding treatment to the plant stems regaining moisture through superheated steam and drying, screening and chopping up expanded threadlike expanded plant stems. The device comprises a moisture regaining device, a feeding device, a heating and pressurizing device and an expansion device, wherein the feeding device, the heating and pressurizing device and the expansion device are communicated sequentially. The inner ring surface of a spray nozzle of a venturi expansion pipe is evenly provided with tooth-shaped ribs. A slitting device is a roller splitting machine. The method and the device for preparing the cut expanded plant stems can remarkably improve processibility and utilization ratio of the plant stems.

Description

technical field [0001] The invention relates to a processing method and equipment for plant stems, in particular to a process method for expanding plant stems into silk. [0002] The invention also relates to a device for realizing the plant stem expansion silk making method. Background technique [0003] At present, the tobacco industry mainly has the following two methods to deal with the discarded tobacco stems: one is sheet technology; the other is expansion technology. The former produces cut stems with low filling value, insufficient aroma and heavy impurity gas during burning and smoking; while the expanded tobacco stem produced by the latter has high filling value, strong aroma during burning and smoking, and can reduce the tar content of cigarettes and enhance cigarette smoking. Cigarette Safety. In recent years, tobacco stem expansion technology has developed rapidly. For example, Chinese patent 200510118934.6 discloses an ESS process for preparing granular expan...
