Here`s the scenario:
A 2nd hand cask washing machine has been delivered today. It has an immersion element, to heat a tank of caustic, which is jetted around the inside of a beer keg, at a specified temperature, in order to kill and bacteria within.
The uses it previously had called for the detergent bath to be heated to 47 degrees C maximum ( a typical 2 wire stat & controller are used to fire or hold off the immersion element. There is no internal thermostat fitted to the immersion, which is normal for these machines.)
The use to which it will be put, calls for the caustic to be heated to 85-90 degrees C - allowing for the temperature drop when it is pumped around the inside of a metallic beer keg.
I know the physical dimensions of the caustic tank. I know the material from which the tank is made ( stainless), and I know the size of the element installed ( 6KW element, wired in single phase config).
How do I begin to calculate the immersion size needed to heat the volume of liquid to the required temp? Anyone care to offer any formulae?
Cheers
