Cut - Tobacco Drying Cylinder With Plate Thermal Exchanger Tobacco Primary Drier

SH6/NH1 Series of Cut -tobacco Drying Cylinder with Plate Thermal Exchanger

Application:

The product is used in tobacco primary processing line for quick drying of cut-lamina or cut-stem at high temperature ,which can remove greenish odor and free nicotine.As the result ,the taste of cut-tobacco becomes mild and rich in aroma and flavor.The quick drying process can result in good curl,looseness,and improve filling power of the cut-lamina or cut stem.

Features:

-With adjust and control range of 0.5-1.1 times of rated capacity based on keeping existing machine size .

- Free adjustment of hot air temperature within the range of room temperature ~140°C.

-Single hot-air flow direction changed to be multiple : concurrent, countercurrent,and concurrent /countercurrent with automatic changeover for option ,so as to meet user’s personal demand on special technology process.

-Alternative two control modes on user’s special technology process for option:

a) Control over temperature of thermal exchanging plate (regulating temperature of inner wall of cylinder for controlling output moisture content and temperature ect.while keeping constant hot air parameters.)

b) Control over parameters of hot air (regulating parameters of hot air for controlling output moisture content and temperature etc.while keeping constant temperature of inner wall of cylinder).

-Solution for reducing over -drying phenomenon at the beginning and the end of drying process .Adaptive time-variable moistness field at the rear part of cylinder for further reducing amount (below 0.5% per batch) of over -drying cut -tobacco.

-Changing the inclined angle of Rake -plate for thermal exchanging to increase area of heat radiation surface and reduce falling height of cut-tobacco,resulting in less degradation and increasing drying strength.

-Changing thermal exchange plate’s steam flow inside cylinder for better thermal field distribution and thermal stress inside.

-Intelligent control over both process parameters and output parameter.

-Intelligent expert system is set as per process parameters and output parameters to meet requirement of batch processing.

-Cylinder with auto jacking up device for option ,for purpose of convenient maintenance and reducing compression against support roller during downtime.
