The short distance distiller works under
the high vacuum condition , it has special
demands in shaving the diaphragm and built-in
condenser , for reduce liquid film thickness
and strengthen displacement , liquid of
layer, HEC according to blow diaphragm pattern
divide into the following 2 kinds Company
：
● Short distance distiller of
Model SPE-A ：
Blow diaphragm pattern for radial person
who slip , it blow by WFE-VA membrane evaporimeter
develop; Blow slice inlay U in rotor lead
trough , blow slice lead centrifugal function
from U trough radial is it heat the cliff
side to slip to when the rotor is rotated.
Lead trough even to distribute in rotor
circumference (see 1 Fig.), rotor present
mouse cage type, have dynamic vapour liquid
separate the device between leading trough,
the ones that prevent the drop splash and
carrying secretly 。
It blows one stretch of materials generally
by polytetrafluoroethylene (PTFE) , graphite
,etc. Composition 。
● Short distance distiller of
Model SPE-B ：
Shaving the diaphragm and is similar to
WFE-VC (Fig. 2 ) of the same SVE-VB, shave
the diaphragm to stick in heating the cliff
side closely by the centrifugal force. It
blows stretch and is prevented the metal
from wearing and tearing by the limit location
in the short distance distiller of Model
SPE-VB, this characteristic is very important,
in case deal with color sensitive supplies,
because supplies this whether volatility
composition flow through these distiller,
its color is not influenced because the
metal is worn and torn . This type is used
extensivly, by changing frequency and quality
which shave slice, regulate the centrifugal
force to meet various kinds of viscidity.
Shave the board material and usually adopt
the metal material the same as barrel of
the evaporimeter , can adopt PTFE material
。
