Abstract

Abstract An autoclave apparatus comprising an autoclave forming a product-receiving chamber having an inlet port in one end and an outlet port in the opposite end and being, further, formed with an access opening. An electrically heated heat exchanger is formed with a chamber which contains heat storage means and such chamber has an inlet in one end and an outlet in the opposite end. Conduits connect the inlet to the autoclave with the outlet from the heat exchanger and the outlet of the autoclave with the inlet to the heat exchanger. Means is provided for supplying gas to the system whereby such system may be pressurized with the gas and such gas circulated through the autoclave and in heatexchange relationship with the heat storage means to heat such gas to an elevated temperature thereby providing an atmosphere in the product-receiving chamber of the desired temperature and pressure.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 228 words
An autoclave system, comprising: an autoclave formed with a product-receiving chamber having a inlet port, outlet port, and including an access opening: a heat exchanger formed with a chamber having an inlet and an outlet; heat storage means disposed in said chamber formed by said heat exchanger; an electric heater disposed in said heat exchanger in heat exchange relationship with said heat storage means; a first conduit connecting the inlet port of said autoclave with the outlet port of said heat exchanger; a second conduit connecting the outlet port of said autoclave with the inlet port of said heat exchanger; a blower for circulating gas through said autoclave and heat exchanger; gas storage tank having an outlet a third conduit connecting the outlet of said storage tank with said heat exchanger; gas control means in said third conduit for controlling gas flow from said gas storage tank to said heat exchanger; vent valve means connected with said autoclave for releasing pressure therein; and electrical control means for controlling the current to said electric heater whereby said heater may be actuated to heat said heat storage means, said gas control means actuated to pressurize said autoclave and heat exchanger, and said blower actuated to circulate said gas through said heat exchanger and in heat exchange relationship with said heat storage means to heat said gas to an elevated temperature.
Claim 2
Dependent Claim 228 words
An autoclave system, comprising: an autoclave formed with a product-receiving chamber having a inlet port, outlet port, and including an access opening: a heat exchanger formed with a chamber having an inlet and an outlet; heat storage means disposed in said chamber formed by said heat exchanger; an electric heater disposed in said heat exchanger in heat exchange relationship with said heat storage means; a first conduit connecting the inlet port of said autoclave with the outlet port of said heat exchanger; a second conduit connecting the outlet port of said autoclave with the inlet port of said heat exchanger; a blower for circulating gas through said autoclave and heat exchanger; gas storage tank having an outlet a third conduit connecting the outlet of said storage tank with said heat exchanger; gas control means in said third conduit for controlling gas flow from said gas storage tank to said heat exchanger; vent valve means connected with said autoclave for releasing pressure therein; and electrical control means for controlling the current to said electric heater whereby said heater may be actuated to heat said heat storage means, said gas control means actuated to pressurize said autoclave and heat exchanger, and said blower actuated to circulate said gas through said heat exchanger and in heat exchange relationship with said heat storage means to heat said gas to an elevated temperature.
Claim 3
Dependent Claim 49 words
An autoclave system as set forth in claim 1 wherein: said autoclave includes a return passage for receipt of gas passed over said product to return said gas to said autoclave inlet port for mixing with incoming gas to cool said incoming gas to avoid overheating of said product.
Claim 4
Dependent Claim 22 words
An autoclave system as set forth in claim 1 that includes: valve means in said first conduit for controlling gas flow therethrough.
Claim 5
Dependent Claim 22 words
An autoclave system as set forth in claim 1 that includes: valve means in said second conduit for controlling gas flow therethrough.
