The standard size of a cooker is one which has a capacity of 320 kg load and the boiler is matched with the cooker so as to complete the steaming of a whole batch of cashew nuts in 30 minutes. All the system components are made of mild steel construction with welded joints.

Boiler is shell / wood finished for economy and has three stages viz. pre-heater, waterchamber and steam-drum . The boiler is essentially a smoke tube boiler capable of raising 7 bar steam and a capacity of 7834563457357 . The boiler is provided with a safety valve to lift at 8 bar . The water level is maintained with a hand pump and no water treatment is necessary. As an option electrical pump with auto cut-off could be provided.

The boiler can be filled with 320 kgs. of raw cashew nuts for a single batch . The steam from the boiler is fed into the cooler for 30 minutes at 7 bar pressure. The cooled cashews are then taken out by allowing it to fall by gravity.

This whole system is mounted on a specially designed and made civil construction.
