CLIMBING FILM PIPE
EVAPORATOR
MODEL: BP 210
HE Climbing Film Pipe Evaporator (Model: BP 210) has been designed for student demonstration
on climbing film evaporation process. This floor standing pilot-plant unit consists mainly of an evaporator
tube, a feed tank, a feed pump, a cyclone separator, vessels for distillate and concentrate, and a
vacuum pump. The unit is suitable for the evaporation and concentration of heat sensitive products such as
milk, fruit juices, etc. Using the existing laboratory steam supply students will conduct experiments to study the
effects on evaporation rate of feed flow rate and temperature, and evaporator temperature and pressure. Students
will also study the effect of process parameters on the evaporator economy.
T
The dilute feed from the feed tank enters the bottom
of the evaporator tube, on the outside of which steam
is condensing. The feed is often below its boiling
point, and for a short distance, the feed to the tube
flows upward as a liquid and receives heat from the
condensing steam. Bubbles of vapour are formed
when boiling of the liquid commences, and they
increase the linear velocity of the flow, thus increasing
the rate of heat transfer. Towards the end of the tube,
bubble growth is rapid, and bubbles of vapour
alternating with slugs of liquid rise quickly through the
tube and discharge at a high velocity from the top.
The resulting mixture of liquid and vapour then enters
the separator, where the linear velocity of the vapour
is reduced, allowing the separation of the liquid and
vapour streams to take place. The concentrated liquor
can then be removed from the system (once through
operation) or can be recycled for further concentration
(re-circulation). The vapour leaves the top of the
separator to a condenser and collected or discarded
as distillate.
