Sectional type low temperature roller cut tobacco drying equipment

Abstract

The invention discloses a sectional type low temperature roller cut tobacco drying equipment, comprising a barrel body, a feeding cover, a discharging cover and moisture exhaust pipelines, wherein, the feeding cover and the discharging cover are arranged on the two ends of the equipment and are respectively connected with a moisture exhaust pipeline on the equipment; the inner barrel wall of the barrel is uniformly distributed with semi-circle pipes and hot wind introducing pipelines; the barrel is internally provided with a cooking plate; wherein, the barrel is a sectional barrel with at least a high temperature zone and a low temperature zone; the barrel body is internally installed with a low hot wind pipeline and a high hot wind pipeline which is contained on the low hot wind pipeline; the two pipes and the barrel body are connected to form a wire spoke which can revolve synchronously; the inlets of the low hot wind pipeline and the high hot wind pipeline are respectively connected with a hot wind heater and an air blower which are externally corresponded to the inlets; the cooking plate is arranged in radial direction in the high hot wind pipeline. As the barrel temperature and the hot wind temperature can be respectively adjusted and controlled sectionally, the adjustment of height difference of the temperature of two-section barrel body and hot wind temperature and the cross current between hot wind and materials can achieve different processing strength and uniformity of cut tobacco drying, and can improve entirely comprehensive aesthetic quality and processabilityresistance of tobacco.

Description

technical field [0001] The invention relates to shredded tobacco drying equipment on a tobacco shredded production line, in particular to a sectioned low-temperature drum shredded shredded drying equipment, which can effectively control the temperature of the shredded tobacco drying equipment, the temperature of hot air and adjust and control the sections separately. Background technique [0002] At present, there are mainly two structural forms of drum-type shred drying equipment used in domestic and foreign tobacco industries: drum tube-sheet type and drum sheet type. The drying principles, process requirements and structural characteristics of the two are roughly similar. The drying principle is to use saturated steam as the heating medium to provide heat for the cylinder and hot air. Through heat transfer and exchange, the drying of shredded tobacco is realized. Purpose. The pipeline control system configured by the equipment is also mainly adapted to saturated steam. ...
