Weighing system for a gas ring burner set up with gas cut off when liquid evaporates to lesser weight

摘要

A method of cutting off a gas supply of a gas burner to prevent over evaporating a liquid during cooking comprises turning the gas off as a function of the amount of evaporation of a liquid monitored using a weighing system attached or integral with the burner. The weighing system may be used in combination with an electrical cooker. Liquids include stocks, soups, sauces, casseroles or curries. The weighing system may be programmable.
