Cut tobacco over-dried temperature and pressure increasing pipeline type conditioning system

Abstract

The invention discloses a cut tobacco over-dried temperature and pressure increasing pipeline type conditioning system. The system is additionally arranged beside a main production line, and comprises a feeding conveying belt, a conditioning device, a gas and material separation chamber and a discharging conveying belt, wherein the feeding conveying belt, the conditioning device, the gas and material separation chamber and the discharging conveying belt are connected in sequence; the conditioning device comprises an atomizing nozzle, an initial conditioning barrel, a steam nozzle and a conditioning chamber; the atomizing nozzle is positioned above the initial conditioning barrel; a gas lock is arranged at the bottom of the initial conditioning barrel; the steam nozzle and the initial conditioning barrel chamber are positioned below the initial conditioning barrel. The system realizes rapid and uniform conditioning of over-dried cut tobacco through cut tobacco initial conditioning and temperature and pressure increasing pipeline type conditioning, reduces the conditioning time, realizes the same batch conditioning, reduces breakage of over-dried cut tobacco, guarantees the completeness of cigarette blend, and reduces the influence on the sensory quality of cut tobacco.

Description

technical field [0001] The invention belongs to the technical field of cigarette processing equipment, and in particular relates to a temperature-increasing and pressurizing pipeline-type dampening system for the dry head and tail of dried shredded leaves. Background technique [0002] Shredded drying is an important process in the process of making shredded tobacco, which has a direct impact on the sensory quality of shredded tobacco and cigarette production. Usually, at the beginning and end of the production of the shredded shredded machine or when the equipment starts and stops abnormally, because the material flow of shredded tobacco does not match the dehydration amount of the shredded shredded dryer, a certain amount of dry shredded tobacco will inevitably be produced. Therefore, drying the shredded tobacco at the head and tail has always been a difficult problem in the tobacco industry. [0003] In the prior art, the processing for dry cut tobacco mainly focuses on ...

AI Technical Summary

Problems solved by technology

Among the above three types of methods: in method (1), after adding water to the material, the moisture only stays on the surface of shredded tobacco to affect the sensory quality of shredded tobacco; in method (2), the water addition capacity of the heating and humidifying equipment is limited (2-3%), And the principle of the silk drying machine is to use the heat conduction effect, so adding steam atomized water to the hot air pipe (vertical pipe wall) has little effect on the temperature of the cylinder wall, and even affects the program control of the silk drying machine; in method (3), through Adding a side-line intermittent dampening cylinder can rehydrate the shredded tobacco in time, but the throwing movement of the drum will greatly break the shredded tobacco, and the intermittent feeding and feeding method of the drum also increases the dampening cycle; through the installation The flowing moisture resurgence tunnel can process the dry cut tobacco in time, but because of the static distribution method, the moisture regain of the cut tobacco at the center of the material and the cut tobacco on the surface will be uneven
