CLIMBING FILM PIPE

EVAPORATORMODEL: 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

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.

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.
