Abstract
Abstract PCT No. PCT/EP85/00739 Sec. 371 Date Aug. 25, 1986 Sec. 102(e) Date Aug. 25, 1986 PCT Filed Dec. 24, 1985 PCT Pub. No. WO86/03654 PCT Pub. Date Jul. 3, 1986.A process is described for manufacturing of farinaceous products in which the soft farinaceous product leaving a molding head is conveyed through differentially heated climatic zone and is cooled and/or dimensionally stabilized after completion of the drying process. The farinaceous product is heated to a temperature of 80 DEG to 100 DEG C. with at least slight initial drying and freshly expanded superheated steam is then allowed to flow around it for about 30 seconds to 20 minutes. In this process the native starch of the boundary layer of the farinaceous product is converted into swelling starch. Finally the farinaceous product is dried in a controlled drying climate.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
171 words
In a process of manufacturing farinaceous product having a final moisture content of about 11 to 13% by weight, wherein the farinaceous product, which leaves a molding head in the form of a soft material which is moist and moldable is conveyed through differentially heated climatic zones to final drying and the farinaceous product is cooled or dimensionally stabilized after completion of the drying process, the improvement comprising heating farinaceous product upon leaving a molding head in a climatic zone to a temperature of 80° to 100° C. with initial drying sufficient only to remove superficial stickiness of the product, then converting the native starch of the boundary layer of the farinaceous product into swelling starch by employing freshly expanded and super heated steam by allowing the steam to flow around the product for about 30 seconds to 20 minutes so as to avoid a film of water developing on the surface of the product, and then drying the farinaceous product in a controlled drying climate to said final moisture content.
Claim 2
Dependent Claim
171 words
In a process of manufacturing farinaceous product having a final moisture content of about 11 to 13% by weight, wherein the farinaceous product, which leaves a molding head in the form of a soft material which is moist and moldable is conveyed through differentially heated climatic zones to final drying and the farinaceous product is cooled or dimensionally stabilized after completion of the drying process, the improvement comprising heating farinaceous product upon leaving a molding head in a climatic zone to a temperature of 80° to 100° C. with initial drying sufficient only to remove superficial stickiness of the product, then converting the native starch of the boundary layer of the farinaceous product into swelling starch by employing freshly expanded and super heated steam by allowing the steam to flow around the product for about 30 seconds to 20 minutes so as to avoid a film of water developing on the surface of the product, and then drying the farinaceous product in a controlled drying climate to said final moisture content.
Claim 3
Dependent Claim
20 words
Process as claimed in claim 1, wherein the farinaceous product is treated for 1 to 15 minutes with superheated steam.
Claim 4
Dependent Claim
49 words
Process as claimed in claim 1, including the step of heating farinaceous product of large wall thickness in less than 30 minutes, those of medium wall thickness in less than 20 minutes and those of thin wall thickness in about 5 to 10 minutes to 80° to 100° C.
Claim 5
Dependent Claim
53 words
Process as claimed in claim 1, wherein the farinaceous product is heated in a first climatic zone through one or more temperature jumps in the climatic stages subdividing first climatic zone, the dew point of a subsequent climatic stage within this first climatic zone being below the temperature of the preceding climatic stage.
Claim 6
Dependent Claim
32 words
Process as claimed in claim 1, wherein water-based farinaceous product is heated in less than about 20 minutes and treated in the course of about 5 to 15 minutes with superheated steam.
Claim 7
Dependent Claim
51 words
Process as claimed in claim 5, wherein drying is carried out at a temperature of about 75° to 100° C. while adhering to a total treatment time of less than about one hour, as determined from the instant in time of the emergence from the molding head to the final drying.
Claim 8
Dependent Claim
62 words
Process as claimed in claim 1, where egg-based farinaceous product is heated in less than about 30 minutes from the emergence from the molding head and dried at a temperature of about 70° to 95° C. while adhering to a total treatment time of about two to three hours, as determined from the emergence from the molding head to the final drying.
Claim 9
Dependent Claim
69 words
Process as claimed in claim 1, wherein farinaceous product of high protein content is heated, treated with the superheated steam and then dried at a temperature of less than about 80° C. to a moisture content of less than about 13% by weight while adhering to a total treatment time of about three to five hours, as determined from the emergence from the molding head to the final drying.
Claim 10
Dependent Claim
79 words
Farinaceous products resulting from a process as claimed in claim 1, wherein, additionally, the starch of the farinaceous product is still in the native state in the core of the farinaceous product after drying and in the boundary layer or in the region of the entire surface of the portion of material is present in the form of swelling starch and wherein the surface of the dried farinaceous product has a matt surface and is not glassy and shiny.
