Abstract
Abstract Process and apparatus are provided for rapidly stabilizing a food product. The stabilization may take the form of either fixing or glueing a coating to the food product, treating the surface thereof to impart a particularly desired property such as rigidity or shape retention to the end product after further treatment thereof, cooking the entire product or a combination thereof. The product to be treated is moved through one or more processing chambers wherein it is contacted only by superheated steam, air having been excluded from the chambers. Saturated steam is supplied in a non-superheated condition at atmospheric pressure and remains substantially at atmospheric pressure throughout its movement through the apparatus. The steam is superheated within the chambers by the use of heating elements located within the chambers. By supplying the chambers with more steam than is sorbed by the food product during its treatment, air is effectively excluded from the chambers. In a preferred embodiment, two main product treatment chambers are arranged in tandem with the steam within the chambers capable of being automatically maintained at different pre-selected temperatures to process the food products differently in each chamber.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
73 words
A method of fixing an edible coating to a food product without frying which comprises applying a starch-containing coating composition to the exterior of a food product, exposing said coated food product to superheated steam at atmospheric pressure in the substantial absence of air for a time which is sufficient to stabilize said coating and adhere said coating to the food product but which is insufficient to substantially cook said coated food product.
Claim 2
Independent Claim
73 words
A method of fixing an edible coating to a food product without frying which comprises applying a starch-containing coating composition to the exterior of a food product, exposing said coated food product to superheated steam at atmospheric pressure in the substantial absence of air for a time which is sufficient to stabilize said coating and adhere said coating to the food product but which is insufficient to substantially cook said coated food product.
Claim 3
Dependent Claim
84 words
The method according to claim 1 including providing at least a first food processing chamber, continously passing a plurality of said coated food products through said chamber, supplying an amount of steam to said chamber sufficient to blanket said food products with steam and to have a continuous outflow of steam from said chamber; and permitting said excess amount of steam to exit from said chamber thereby ensuring the fixing of said edible coating to said food products in the substantial absence of air.
Claim 4
Dependent Claim
21 words
The method according to claim 2, including supplying saturated steam to said chamber and superheating said steam only within said chamber.
Claim 5
Dependent Claim
54 words
The method according to claim 2, including providing first and second contiguous food processing chambers, coninuously passing said plurality of said coated food products through said first and second chambers, in turn; and supplying a greater amount of steam at a lower degree of superheat in said first chamber than in said second chamber.
Claim 6
Dependent Claim
32 words
The method according to claim 4, wherein said degree of superheat in said first chamber is approximately equal to 525° F. and in said second chamber is approximately equal to 625° F.
Claim 7
Independent Claim
179 words
A method for continuously rapidly stabilizing a plurality of coated food products to fix an outer coating containing starch thereto, without frying, prior to further processing of said coated food products while the interior thereof remains substanially uncooked, said method comprising: placing said coated food products in a processing oven for a predetermined time, said oven having at least a first food processing chamber constructed to continuously pass said coated food products therethrough; maintaining said processing chamber at substantially atmospheric pressure; supplying saturated steam, at substantially atmospheric pressure, to said processing chamber in an amount in excess of the amount to substantially fill said processing chamber and blanket said food products; superheating said steam only within said processing chamber; permitting said excess amount of steam to exit from said processing chamber thereby maintaining the exclusion of substantially all of the air from said processing chamber and aiding in maintaining said chamber at substantially atmospheric pressure; said predetermined time being only sufficient to rapidly fix said starch-containing coating to said food products while maintaining said coated food products substantially uncooked.
Claim 8
Independent Claim
179 words
A method for continuously rapidly stabilizing a plurality of coated food products to fix an outer coating containing starch thereto, without frying, prior to further processing of said coated food products while the interior thereof remains substanially uncooked, said method comprising: placing said coated food products in a processing oven for a predetermined time, said oven having at least a first food processing chamber constructed to continuously pass said coated food products therethrough; maintaining said processing chamber at substantially atmospheric pressure; supplying saturated steam, at substantially atmospheric pressure, to said processing chamber in an amount in excess of the amount to substantially fill said processing chamber and blanket said food products; superheating said steam only within said processing chamber; permitting said excess amount of steam to exit from said processing chamber thereby maintaining the exclusion of substantially all of the air from said processing chamber and aiding in maintaining said chamber at substantially atmospheric pressure; said predetermined time being only sufficient to rapidly fix said starch-containing coating to said food products while maintaining said coated food products substantially uncooked.
