Heat cooking/sterilizing device
First Claim
1. A heating, cooking and disinfecting apparatus comprising:
- a hermetic type of pressurizing-and-depressurizing cooking vessel defining an inside and a bottom, and having a plurality of nozzles in said arranged inside, said nozzles being joined together and to a supply conduit assembly, said cooking vessel having a return conduit and a drain outlet provided on said bottom;
a heat exchanger having an inlet and an outlet connected to said return conduit and said supply conduit assembly respectively, thereby forming a circulation channel;
a water supply;
a seasoning liquid supply;
a steam supply;
a cold water supply;
a superheated vapor supply;
a heated nitrogen supply; and
a control wherein;
said water supply and said seasoning liquid supply being arranged so as to be connected alternatively to said circulation channel via associated valves whereas said steam supply, cold water supply, superheated vapor supply and heated nitrogen supply being so arranged that any one of these supplies and said outlet of said heat exchanger may be connected alternatively to said circulation channel downstream of said supply conduit assembly, said cooking vessel having a temperature detecting sensor, a pressure detecting sensor and a nitrogen concentration detecting sensor installed therein; and
said control being responsive to signals from all of the selecting sensors for permitting said nozzles to shower the food material with the seasoning liquid, water, steam, superheated vapor, heated nitrogen or cold water according to the sequencer program associated with said control;
thereby cooking and disinfecting the food material in said cooking vessel.

Abstract
A hermetic type of cooking vessel with numerous nozzles arranged therein, and conduits which open at these nozzles are connected to a cold water source, a hot water source, a seasoning liquid source, a steam source, a superheated steam source and a heated nitrogen source via associated switching means. With this vessel food material is heated evenly without agitating the food material; and automatically heated with this vessel and cooked with accuracy. Thus, the food material is showered with the heated seasoning liquid and other cooking gases and liquids, and the used seasoning liquid is collected from the bottom of the cooking vessel to be reheated. The so reheated seasoning liquid is made to return to the cooking vessel. The cooking vessel is equipped with a food material temperature sensor, a pressure sensor and such like. In response to the signals from these sensors the temperatures of the seasoning liquid, hot water, steam, superheated steam, superheated nitrogen and cold water are controlled and these liquid and gases are supplied to the nozzles according to the sequencer program. Thus, the food material is disinfected and cooked in the cooking vessel under controlled pressure.
