Embodiment 1

[0032] Embodiment 1: shredded tobacco compression

[0033] Set tobacco bulk density: 200kg / m 3 , the diameter of the shredded tobacco holding device is 10cm, and the height of compression is set to 6cm, then the required shredded tobacco mass is calculated to be 94.2g.

[0034] Under constant temperature and humidity conditions, weigh 94.2g of shredded tobacco, and slowly throw the shredded tobacco in the shredded tobacco holding device through the shredded tobacco throwing device. Since the shredded tobacco falls slowly, the shredded tobacco will be evenly spread on the bottom of the shredded tobacco holding device. It presents a similar natural accumulation state in the process of production and processing. Then take off shredded tobacco throwing device, put into compression device, according to the packing density of setting, the height of the compressed tobacco block is 6cm, and the weight bar is fixed on the scale indicator line place that depression bar sets. After a p...

Embodiment 2

[0035] Embodiment 2: sheet tobacco compression

[0036] Set the bulk density of laminar smoke: 200kg / m 3 , the diameter of the shredded tobacco holding device is 20cm, and the compression height is set at 8cm, then the mass of tobacco sheet required is calculated as 502.4g.

[0037] In the constant temperature and humidity chamber, weigh 502.4g of tobacco flakes, and slowly throw the flakes of tobacco in the shredded tobacco holding device through the shredded tobacco throwing device. Since the shredded tobacco falls slowly, the shredded tobacco will be evenly spread on the shredded tobacco The bottom of the storage device presents a similar natural accumulation state during the production and processing process. Then take off shredded tobacco throwing device, put into compression device, according to the packing density of setting, the tobacco piece height of being compressed is 8cm, weight bar is fixed on the scale indicator line place that depression bar sets. After a per...

Abstract

The invention discloses a device for compressing cut tobacco to the assigned stacking density. The device comprises a cut tobacco containing device (1), a cut tobacco throwing device (2), a compression device and a constant-temperature and constant-humidity sleeve. The compression device comprises a circular pressing sheet (3) made of hard materials, and a pressing rod (31) vertically arranged at the upper portion of the center of the circular pressing sheet (3), the diameter of the circular pressing sheet (3) is slightly smaller than the diameter of the inner wall of the cut tobacco containing device (1), and the pressing rod is provided with scale indication lines (311). The constant-temperature and constant-humidity sleeve is arranged on the outer side of the cut tobacco containing device (1) in a sleeving manner. According to the device, a whole compressed cut tobacco block can reach the assigned density, and the density of the cut tobacco block is very uniform.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and in particular relates to a device and method capable of compressing sheet tobacco, shredded tobacco and tobacco leaves to a specified packing density. Background technique [0002] In the production process of tobacco, initial roasting, threshing and redrying, storage and leaf storage are all very important processes. In these processes, shredded tobacco and tobacco leaves are in a certain accumulation state, involving a series of thermal processing processes. Shredded tobacco Thermal properties such as temperature, density, thermal conductivity, thermal diffusivity, and volumetric heat capacity are closely related to the conduction heat transfer process. [0003] At present, the cut tobacco processing process mainly changes the processing environment of the cut tobacco by changing the process parameters. The change of the processing environment will bring about the change of the thermal phys...
