Sectional cylinder cut tobacco dryer

Abstract

The invention provides a novel energy-saving sectional cylinder cut tobacco dryer capable of arbitrarily setting the temperature in a design range to realize high-precision temperature control and high heat utilization rate. The novel energy-saving sectional cylinder cut tobacco dryer comprises a heat conducting oil circulating oil temperature controller, a drying cylinder, a hot air moisture removing system and the like, wherein the drying cylinder is divided into a feeding section drying cylinder and a discharging section drying cylinder along the feeding direction and discharging direction of cut tobaccos; and corresponding to the high-temperature zone and the low-temperature zone of the drying cylinder, the hot air moisture removing system is divided into independent high-heat air section and low-heat air section, a hot air moisture removing pipe is fixedly installed at the other side opposite to the throwing direction of the cut tobaccos without rotating together with the drying cylinder, the axial direction of an air outlet arranged on the hot air moisture removing pipe is approximately intersected with the dropping direction of the cut tobaccos, the air direction of hot air blown into the drying cylinder is intersected with the dropping direction of the cut tobaccos, and the hot air radially flows in the drying cylinder and can uniformly and effectively pass through the throwing layer of the cut tobaccos. By utilizing heat conducting oil for heating the drying cylinder and the hot air, the sectional cylinder cut tobacco dryer has high temperature control precision and heat utilization rate and can meet the process requirements of different cut tobaccos, such as processing strength, drying uniformity and the like.

Description

Technical field:

[0001] The invention belongs to shredded tobacco drying equipment on a tobacco shredded production line, in particular to a segmented drum shredded drying machine for drying shredded tobacco by using hot air and heating the cylinder wall. Background technique:

[0002] Shredded tobacco drying is an important process in the tobacco shredded production process. The goal of the shredded leaf drying process is to remove part of the water in the shredded leaf to meet the specified moisture requirements and accuracy, while increasing the filling value of the shredded leaf, reducing the irritation and miscellaneous gas of the shredded leaf, and improving the odor absorption of the shredded leaf. The drying process generally uses heat conduction and heat convection to heat the wet shredded tobacco, so that the moisture in the wet shredded tobacco evaporates into the barrel, and is taken out of the barrel environment with the flow of airflow inside the barrel.
