Drum-type material loosening and temperature-increasing moisturizing device

Abstract

A roller-type material-relaxing and warming and humidifying device is that a rotary shaft (5) with rake nails (4) outside is arranged along the axial direction inside a roller which is breadthwise arranged. The present invention can completely relax the material and also can completely and uniformly warm and humidify the material, which can completely relax the material as well as commendably make warming and humidifying treatments towards material, accordingly an ideal relaxing effect or warming and humidifying effect is obtained to satisfy the requirement of a subsequent machining.

Description

technical field [0001] The invention relates to the technical field of a drum-type processing device capable of loosening materials or performing temperature-increasing and humidifying treatments or simultaneously performing loosening and temperature-increasing and humidifying treatments. Especially the loosening and warming and humidifying device of tobacco materials. Background technique [0002] The traditional drum-type loosening and warming and humidifying device uses the horizontally inclined drum and the rake nails and copying boards on the inner wall of the drum, so that the materials entering the drum are continuously raked and copied in the process of moving forward. Up and down, so as to achieve the purpose of loose materials. When it is necessary to increase the temperature and humidify the material, use the humidification nozzle and steam nozzle installed at the feed end or discharge end of the drum or both ends to spray water and hot steam on the material, at ...

AI Technical Summary

Problems solved by technology

This device has at least the following disadvantages: the first is that the loosening of the material is only achieved by the rake nails arranged on the inner wall of the drum and the lifting of the material board and the natural fall of the material. The tearing strength of the material is not enough. The range of action on materials is limited, it is difficult to completely loosen large agglomerated materials, and the loosening effect is not ideal; the second is due to the limitations of the equipment's own tube length, tube diameter, process flow and other factors, as well as the heat and humidity cycle in the tube The heat and moisture exchange intensity between the wind and the material is low, which makes the temperature of the material rise slowly, the diffusion and transfer of water are slow, and the effect of warming and humidifying is not ideal; the third is that the atomized water directly sprayed out by the humidifying nozzle installed at the end of the drum can only cover Too much water is added to the surface of some materials, and the temperature inside the material is not high, the atomized water on the surface cannot be diffused and transferred in time, the material absorbs water unevenly, and it is difficult to meet the refinement requirements of subsequent processing
