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.
Technical Specifications:
-Rated capacity:for cut -lamina: 300kg/h~6400kg/h
for cut-stem:270kg/h~3000kg/h
-Output moisture content :11%~14%(set according to technological
requirement ),with deviation of + 0.5%
-Output temperature (set according to technological requirements):
for Grade A and Grade B tobacco :50°C~60°C, for others:55°C~65°
