SCRAPED SURFACE HEAT EXCHANGER |
 A unique Scraped Surface Heat Exchanger specifically designed for processing thick, high viscosity materials and heat exchanging a variety of specially heat sensitive products like fruit pulps of mangoes, papayas, guavas, peaches and juice concentrates. The continuous scraping action exerted on the heat transfer surface ensure uniform heating of the contents, prevents product fouling/burn-out. It is also heavily used for materials that solidifies at the wall temperatures.
The Rotary Scraped Surface Heat Exchanger consists of a stainless
steel tube, suitably jacketted in a carbon steel jacket insulated
from outside and covered with stainless steel sheathing. The
stainless steel centre shaft of the heat exchanger is fitted
with teflon scrapers which scrape the internal surface of
the heat exchanger continuously. The positive displacement
pump ensures constant product infeed. Cleaning procedures
are simple and easy at the end of a run, without need to dismantle
the product contact parts for inspection.
The unit is complete with motor and necessary fittings. Optional
extras include starter, temperature controller and recorder,
and automatic product flow control.
Depending upon the capacity requirement, multiple units can
be supplied in series or parallel working arrangement.
The unit can also be used as an efficient product cooler,
by using a suitable coolant. With appropriate modifications
such as addition of necessary flash chamber, barometric/semi-barometric
condenser with vaccum pump, etc., the heat exchanger can also
be used as a thin film evaporator mainly for concentration
of thick, viscous, delicate and heat sensitive products.
Single effect/double effect evaporator may also be offered
for concentration of viscous or heat-sensitive products which
are otherwise difficult to be concentrated by other conventional
means.
500 to 10,000 litres per hour. Depending on the objective
and viscosity of product and process requirement Electric
Power will be calculated for each application. |
