Rendertech evaporators, when used in rendering and fishmeal industries, maximise the return from raw materials, increase plant yields and eliminate a high-strength wastewater stream. Our Waste Heat Evaporator is a falling film-type evaporator operating under a vacuum. Simple and robust construction makes it very easy to operate and maintain.
FEATURES & BENEFITS
Shell and tube construction
Full stainless steel shell and tube construction means long life, reduced fouling, and
easier and less frequent cleaning.
Waste heat utilisation for energy efficiency
The Evaporator is powered by waste energy – the vapour-rich
mixture from a Contact Drier or equivalent – making it incredibly energy efficient.
Falling film principle
Process liquor is pumped to the top of the evaporator tubes and distributed to the
individual tubes. The liquor forms a thin film as it flows down the inside of the tubes. Vapour from the drier is ducted to the outside
of the tubes and the heat is transferred to the liquor. The high liquor recirculation rates reduce fouling.
Free hot water
The vapour produced by evaporation is ducted to the Vacuum Condenser, where it can produce
potable hot water up to 55°C.
Multiple effects and customised design
Evaporators can be supplied with one, two or three effects. The optimum
selection will depend on the waste heat available and liquor to be concentrated. We can also provide Evaporators using the ‘forced flash’
principle where higher concentrations are required.
Automatic control
Automatic control and monitoring allows all operating adjustments at the control panel and
minimises labour requirements.
OPTIONS
'Rendertech's solution has given us a state-of-the art plant. The compressed air cleaning solution gives standards of automation not seen before in NZ using this technology. The benefit of the compressed air injection solution, in automatically cleaning and unblocking the 100m pipe was a key reason for us choosing this solution and has worked perfectly from day one.'
We look forward to hearing from you!
