Cylindrical vacuum charger

Abstract

The invention relates to an automatic tobacco charging machine, which belongs to the main equipment in the tobacco shredding process. The charging machine comprises a charging barrel adopting a cylindrical barrel with an interlayer; a rotating shaft arranged at the position of the horizontal cross corner of the barrel; a pair of material covers arranged at the position of the other vertical cross corner of the barrel; a vacuum extraction pipe, a feed liquid pipe and a steam pipe feeding into the barrel; a material liquid sprayer and a steam sprayer positioned on the upper section of the barrel; and a hot water inlet and outlet communicating with the interface of the barrel. The automatic tobacco charging machine can receive the feed liquid sprayed from the above sprayer according to a set ratio in a vacuum environment of the tobacco material, in a continuous turning stage and in an environment at a certain temperature, thus making the material absorption process of tobacco laminas more uniform, faster and more complete, improving the chemical property of tobacco laminas, further removing damage, reducing tar, and improving taste.

Description

technical field [0001] The invention relates to a novel mechanism automatic feeding equipment, which belongs to the host equipment in the tobacco shred making process. It is suitable for the pretreatment of tobacco sheets, adopting different process parameters for different components of tobacco sheets, applying different components of functional material liquids, and performing "modification treatment" on tobacco sheets. At the same time, it is suitable for the process of applying brand liquid to formula tobacco sheets, and applying lining and surface materials when processing burley tobacco. Background technique [0002] Adding in the traditional sense is to spray a feed liquid composed of sugar, humectant, flavoring agent and other substances to the tobacco sheet after the formulation of the tobacco sheet. All formulation components will absorb the same fluid after spraying. The current "grouping processing" process is to spray different components of the tobacco sheet ...

AI Technical Summary

Problems solved by technology

[0005] 1. Uneven distribution of feed liquid: From the section of the feeder, the smoke sheet that can absorb the feed liquid from the nozzle accounts for less than 1 / 3 of the total smoke sheet, no matter how the flow rate of the plunger pump matches the flow rate of the smoke sheet material This macroscopic uneven state cannot be changed, and the feeding accuracy in the process specification is only the measurement accuracy of the flowmeter during the feeding process, which cannot reflect the real distribution accuracy of the feed liquid on all smoke sheets. The real distribution accuracy of the feed liquid mainly depends on the follow-up The mutual penetration between the smoke sheets in the leaf storage cabinet is achieved, and this uniformity is extremely unreliable

[0006] 2. The material liquid absorption process is too slow: the open barrel can only make the tobacco sheet absorb the material liquid under normal pressure, the suction speed is relatively slow, the material is stored in the leaf storage cabinet, and the storage time needs to be very long. Generally, the moisture content of tobacco leaves 18-20%, it needs to be stored for 24 hours at a temperature of 35-50°C before it can be basically absorbed

In order to speed up the suction speed, a 90°C circulating hot air is added from the inlet. Although this improvement seems to improve the hand feeling of the material at the outlet, the hot air will inevitably take away a lot of material liquid and volatiles in the material liquid. The original intention of the feed liquid formula, and how much feed liquid the hot air will take away is an unknown quantity, and the hot air temperature is too high, and the aroma contained in the smoke sheet material itself will also be lost

[0007] 3. Incomplete absorption of feed liquid: As mentioned above, this "modification treatment" is a chemical change process. The sprayed feed liquid and the infiltrated feed liquid can only stick to the surface of the smoke sheet material and cannot enter the cell wall of the smoke sheet. Especially when the water content of the tobacco sheet is high, the molecular weight of the feed liquid is relatively large, and it can only enter the cell wall through the surface water layer of the tobacco sheet

It is difficult to achieve the ideal "modification treatment"
