Evaporation is a process for concentrating a solution by vaporizing a part or all of the solvent. In most of the cases the solvent is water. The Pan Evaporator set-up is designed to study the fundamentals of evaporation process. The set-up consists of a jacketed pan evaporator made of stainless steel and an electrically heated steam generator of suitable capacity. To evaporate the solution in pan, steam is allowed to enter in the jacket using a control valve. Steam isproduced in a steam generator, made of Stainless Steel. Steam generator is complete with heater, feed valve, vent valve, steam control valve, pressure gauge, safety valve, drain, level indicator and Digital Temperature controller. A digital temperature indicator with temperature sensor is also provided to observe temperature during experimentation. Condensate is collected from steamtrap for energy measurement. Tilting is done by means of a rotating wheel to empty the pan.

•Arrangement to measure the evaporated volume of solvent is done.

•An ENGLISH instruction manual consisting of experimental procedures, block diagram etc. will be provided along with the Apparatus.

•The whole set-up is well designed and arranged on a rigid structure painted with industrial PU Paint.

Experimentation/Learning Objectives

•To determine the overall heat transfer co-efficient at the boiling point.

Utilities Required

•Electricity Supply: 1 Phase, 220 V AC, 50 Hz, 32 Amp MCB with earth connection (Earth voltage should be less than 5 volts)

•Water Supply (Initial fill)

•Floor Drain.

•Chemicals: Sodium carbonate & distilled water.
