Abstract
Abstract Fruit flakes made by applying a moist mass of fruit pulp, sugar and starchy material to a hot smooth substrate in a thin layer, at least partially dehydrating said layer to form a cohesive film, peeling said film from said substrate and forming said film into an irregular structure, drying said film until it is brittle, and dividing said film into flakes.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
140 words
A process for the production of fruit flakes comprising applying a moist mass consisting essentially of fruit pulp, sugar added to said pulp and starchy material added to said pulp, to a hot smooth rotating cylindrical substrate in a thin layer, said fruit pulp being about 80 to 85 percent by weight of said moist mass, said added sugar being about 5 to 10 percent by weight of said moist mass and said added starchy material being about 5 to 10 percent by weight of said moist mass, maintaining the substrate at a temperature sufficient to cause caramelization of said moist mass, at least partially dehydrating said layer to form a cohesive film, peeling said film from said substrate and forming said film into an irregular structure, drying said film until it is brittle, and dividing said film into flakes.
Claim 2
Dependent Claim
140 words
A process for the production of fruit flakes comprising applying a moist mass consisting essentially of fruit pulp, sugar added to said pulp and starchy material added to said pulp, to a hot smooth rotating cylindrical substrate in a thin layer, said fruit pulp being about 80 to 85 percent by weight of said moist mass, said added sugar being about 5 to 10 percent by weight of said moist mass and said added starchy material being about 5 to 10 percent by weight of said moist mass, maintaining the substrate at a temperature sufficient to cause caramelization of said moist mass, at least partially dehydrating said layer to form a cohesive film, peeling said film from said substrate and forming said film into an irregular structure, drying said film until it is brittle, and dividing said film into flakes.
Claim 3
Dependent Claim
37 words
A process according to claim 1 wherein said forming comprises pulling, pushing, compressing; restraining or stretching said film as it is being removed from said substrate whereby said film is corrugated, curled or waffled with varying thicknesses.
Claim 4
Dependent Claim
16 words
A process according to claim 1 wherein said substrate is heated to 110° to 140° C.
Claim 5
Dependent Claim
20 words
A process according to claim 3 wherein said substrate is heated by saturated steam at about 4 to 6 atmospheres.
Claim 6
Dependent Claim
15 words
A process according to claim 1 wherein vapors formed during said dehydrating are pumped off.
Claim 7
Dependent Claim
16 words
A process according to claim 1 wherein said peeling is carried out by a scraping knife.
Claim 8
Dependent Claim
21 words
A process according to claim 1 comprising causing said film to freely traverse a relatively short path after leaving said substrate.
Claim 9
Dependent Claim
16 words
A process according to claim 7 wherein said short path is approximately 16 to 20 mm.
Claim 10
Dependent Claim
27 words
A process according to claim 7 wherein, after freely traversing said path, said film is placed on a moving support and air is blown underneath said film.
Claim 11
Dependent Claim
27 words
A process according to claim 7 wherein the speed of said support and the speed of said peeling are different whereby said film is compressed or stretched.
Claim 12
Dependent Claim
20 words
A process according to claim 1 wherein said film after said dehydrating is cut lengthwise and divided crosswise into flakes.
Claim 13
Dependent Claim
33 words
A process according to claim 9 wherein said film is pushed over the end of said support so as to protrude freely, permitting said film to break off in the form of flakes.
Claim 14
Dependent Claim
19 words
A process according to claim 1 wherein said film is 1 to 2 mm. thick while on said substrate.
Claim 15
Dependent Claim
24 words
A process according to claim 1 wherein said mass has a weight ratio of wet material to dry material of about 3 to 1.
Claim 16
Dependent Claim
31 words
A process according to claim 1 wherein said mass contains 80 to 85% pulp, 5 to 10% added sugar and 5 to 10% added starchy material, all percents being by weight.
Claim 17
Dependent Claim
10 words
A process according to claim 1 carried out under vacuum.
Claim 18
Dependent Claim
13 words
A process according to claim 1 wherein said starchy material is corn meal.
Claim 19
Dependent Claim
28 words
Fruit flakes consisting essentially of a dried mass of fruit pulp, added sugar, added starchy materials and having an irregular, corrugated, knurled, or waffled structure with varying thicknesses.
Claim 20
Dependent Claim
28 words
Fruit flakes consisting essentially of a dried mass of fruit pulp, added sugar, added starchy materials and having an irregular, corrugated, knurled, or waffled structure with varying thicknesses.
