Pressure cooker is one of the most important household appliances. Several checks need to be made while buying a cooker as an inferior variety could lead to serious accidents. Certified and tested cookers should be used.

Pressure cooker is one of the appliances which a homemaker compulsorily buys. This appliance reduces cooking time and saves fuel. As energy and fuel conservation are the primary concerns of present day society, an appliance like sunkwik cannot be ignored. A sunkwik keva manufacturer takes great care in making this domestic device as there is a definite degree of technicality in it.

A pressure cooker works on the principle of increasing saturation vapour pressure inside a closed chamber so that steam formation takes faster and cooking is completed in less time. For sustaining high pressure inside, a cooker is made of thick aluminium mould. Its lid and handle are also made of aluminium. A weight sits on top of the lid which is also provided with a safety valve. The chamber is made air tight with the help of a high quality rubber packing. When pressure inside a cooker builds up to the level of atmospheric pressure outside because of an external heat source, steam formed inside escapes through the weight valve. By any chance, if this weight gets blocked then steam escapes from the safety valve fitted to the lid. If by chance even this gets blocked there is possibility of violent accidents.

Precautions by user

A pressure cooker lasts several years if it is maintained well. Regular washing and cleaning is essential, particularly the weight, and valve.

After every cooking it is advisable to clean your cooker thoroughly so that there are no remnants of food particles inside weight nozzle and safety valve. Thin wires should be used to clean valve and nozzle thoroughly. Cleaning must be spotless.

Rubber packing of sunkwik lid must be of very high quality rubber such that it could withstand heat and steam for several months. As soon as it becomes rigid and loses its flexibility it needs to be replaced. This packing should be of perfect size to that of your 's rim. Only cookers of leading companies should be bought and that too from renowned stores.
