Abstract
Abstract A fat frier comprising a fat container which contains fat to be heated and in which are disposed a heating means, a sieve-type or mesh-type container for the material to be fried and, beneath the fat to be heated, a layer of water, characterized in that disposed in the fat container, beneath the heating means, are cooling means which cool the fat in the region of the interface between the fat and the water.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
127 words
A fat frier comprising a fat container having an upper zone and a lower zone, said upper zone holding a layer of fat, said lower zone holding a layer of water, the fat and water layers contacting one another to form a fat-water interface, said upper zone including porous container means for holding the material to be fried, and means for heating the fat to frying temperature, means for cooling the heater fat in the region of the fat-water interface to a temperature such that the fat in said region remains fluid, said frier including means for draining the fat layer disposed directly beneath the fat-water interface, and means for draining the water layer disposed at the lowest point of the lower zone of the fat container.
Claim 2
Dependent Claim
127 words
A fat frier comprising a fat container having an upper zone and a lower zone, said upper zone holding a layer of fat, said lower zone holding a layer of water, the fat and water layers contacting one another to form a fat-water interface, said upper zone including porous container means for holding the material to be fried, and means for heating the fat to frying temperature, means for cooling the heater fat in the region of the fat-water interface to a temperature such that the fat in said region remains fluid, said frier including means for draining the fat layer disposed directly beneath the fat-water interface, and means for draining the water layer disposed at the lowest point of the lower zone of the fat container.
Claim 3
Dependent Claim
30 words
A fat frier according to claim 1 characterised in that the cooling means comprises a reduction in the cross-section of the fat container in the region of the fat-water interface.
Claim 4
Dependent Claim
27 words
A fat frier according to claim 2 characterised in that the cooling means is a constriction in the fat container in the region of the fat-water interface.
Claim 5
Dependent Claim
22 words
A fat frier according to claim 2 characterised in that the lower zone of the fat container has a downwardly tapering bottom.
Claim 6
Dependent Claim
19 words
A fat frier according to claim 2 including additional heating means disposed above and adjacent to the fat-water interface.
Claim 7
Dependent Claim
45 words
A fat frier according to claim 5 including a thermostat for controlling the additional heating means, said thermostat sensing the temperature of the fat adjacent to the interface, and preferably holds the temperature of the fat adjacent the interface at about 40° to 50° C.
Claim 8
Dependent Claim
38 words
A fat frier according to claim 2 including a thermostat adapted for switching off the heating means when the temperature of the fat in the region of the fat-water interface exceeds a given temperature, preferably about 70° C.
Claim 9
Dependent Claim
28 words
A fat frier according to claim 1 characterised in that the cooling means is substantially horizontal pipes which are open at both ends and through which flows air.
Claim 10
Dependent Claim
22 words
A fat frier according to claim 8 characterised in that the lower zone of the fat container has a downwardly tapering bottom.
Claim 11
Dependent Claim
19 words
A fat frier according to claim 9 including additional heating means disposed above and adjacent to the fat-water interface.
Claim 12
Dependent Claim
45 words
A fat frier according to claim 10 including a thermostat for controlling the additional heating means, said thermostat sensing the temperature of the fat adjacent to the interface, and preferably holds the temperature of the fat adjacent the interface at about 40° to 50° C.
Claim 13
Dependent Claim
38 words
A fat frier according to claim 11 including a thermostat adapted for switching off the heating means when the temperature of the fat in the region of the fat-water interface exceeds a given temperature, preferably about 70° C.
Claim 14
Dependent Claim
19 words
A fat frier according to claim 8 including additional heating means disposed above and adjacent to the fat-water interface.
Claim 15
Dependent Claim
38 words
A fat frier according to claim 8 including a thermostat adapted for switching off the heating means when the temperature of the fat in the region of the fat-water interface exceeds a given temperature, preferably about 70° C.
Claim 16
Dependent Claim
22 words
A fat frier according to claim 1 characterised in that the lower zone of the fat container has a downwardly tapering bottom.
Claim 17
Dependent Claim
19 words
A fat frier according to claim 1 including additional heating means disposed above and adjacent to the fat-water interface.
Claim 18
Dependent Claim
45 words
A fat frier according to claim 16 including a thermostat for controlling the additional heating means, said thermostat sensing the temperature of the fat adjacent to the interface, and preferably holds the temperature of the fat adjacent the interface at about 40° to 50° C.
Claim 19
Dependent Claim
38 words
A fat frier according to claim 1 including a thermostat adapted for switching off the heating means when the temperature of the fat in the region of the fat-water interface exceeds a given temperature, preferably about 70° C.
