 A
lot of for instance, petroleum serious residual
oil , chemical medicines , medicine , wholefood
, health products , fatty acid ,etc., it is often
temperature sensing, glue the stagnat and/or with
high boiling point supplies . Is it spin off from
other component parts of them these supplies to
want , and keep the quality of the result, can
only rectify under low boiling temperature or
even less than the temperature of seething with
excitement , and can only reduce the hot decomposition
or the function of getting together to minimumly
during very short time , in order to dispel the
destruction to products 。
As operate vacuity to at the 500Pa , can lower
membrane go on of the evaporimeter in membrane
evaporimeter of blowing about. However, it is
if must at China in distillation it operate under
the high vacuums (for instance, pressure at 0.
Between 00100Pa) on the existing problem. Must
select for use steam is it exceed through heat
surface and condensation pigeonhole the bad evaporimeter
between the surface to pigeonhole in products,
therefore the evaporimeter with external condenser
is got rid of outside the distillation course
in high vacuum range of China 。
By contrast, the short distance evaporimeter
of Model SPE is very suitable for this kind of
application occasion, the condenser is made in
the evaporimeter, lie in and heat on the opposite
side where the distillation takes place directly.
So, the short distance evaporimeter is a item
of newer applying to production for industrialization
extensively yet, can solve the new-type separation
technology that a large amount of routine distillation
technology can't be solved 。
The short distance distiller divides into three
kinds of forms according to the form of the membrane
shaving device : Roll membrane , is it blow membrane
, hinge blow membrane , according to viscidity
, punish nature select blowing membrane device
different for use of supplies to slip 。
Characteristic ：
Short the time of staying:
Shave the function of the membrane device , surface
the time of staying is extremely short to make
the liquid film heat 。
Low distillation temperature:
Because condenser is it heat Taxi on the opposite
side to lie in directly, reduce keep difference
, have high vacuity extremely, it is the distillation
that the supplies can not even need the boiling
point under extremely low temperature 。
Contain the solid thing in viscidity
thing and products: The ones that shaved
slice were soaked in deeply, depend on a very
considerable edge, the material membrane causes
a strong shear and mixes the effect, lighten wait
viscidity to deal with liquid, is it deal with
viscidity get 50Pas , is it heat surface marry
dirt to prevent to suitable for, especially suited
to including the solid material liquid 。
The extremely thin distillation liquid:
The function of shaving the membrane device shaves
the material liquid into the extremely thin liquid
film. Separate more completely 。
Hot sensitive supplies ：
High separation than: The accurate
liquid film that shaves the board and is used
extremely thinly is distributed in heating the
surface evenly , result in heating the surface
entirely moistly. It allow not operating it is
high that it is separate to boil to unit like
this than. This means more than 90% that enters
while arranging on record is evaporated, constant
remains in the material the level can be finished
。
