专利汇可以提供Apparatus for filtering cooking liquid专利检索，专利查询，专利分析的服务。并且A filter assembly for use in apparatus for cooking food in a hot cooking liquid, in which the filter assembly is rotated to centrifugally clean the filter medium. The filter assembly is particularly suitable for continuously filtering uncooked and partly cooked foodstuffs from the cooking liquid, and is supported with a cooperating impervious tube spaced therefrom to form a receiving chamber for filtered liquid. The chamber is connected to a conduit for conveying the filtered liquid, for example, back to a supply reservoir for re-use. The filter medium is one of a cloth woven from strands or fibers of a fluorinated ethylene or propylene resin, a silicone-based thermosetting resin or like substance having similar non-stick and low friction characteristics; strands or fibers of the materials mentioned above pressed together into a felt-like mat structure; or a wire screen whose wire strands are substantially wholly coated, preferably with tetrafluorethylene, or another of the above resins. The filter assembly includes means for rotatably mounting the same in a housing. Preferably, at least one turbulencegenerating bar or like structure is provided adjacent the filter surface. This bar creates turbulence in the liquid when the filter assembly is being rotated, and that turbulence tends to loosen filtered material deposited on the filter surface and effects an auxiliary cleansing action on said surface. At least one filter and impervious surface arrangement is provided. Some back flushing also occurs when the filter assembly is cleaned.，下面是Apparatus for filtering cooking liquid专利的具体信息内容。

权利要求

2. The apparatus of claim 1 wherein a plurality of filter medium and impervious annular members are provided to form a corresponding plurality of closed receiving chambers, said conduit means being in communication with each of the receiving chambers for enabling filtered liquid to be conducted therefrom.

3. The apparatus of claim 1, wherein the bottom disc means is provided with channels internally thereof constituting said conduit means for conveying filtered liquid from said receiving chamber.

4. The apparatus of claim 1, wherein turbulence generating means are provided adjacent and exteriorly of the filter medium, said turbulence generating means being fixedly supported and operable to generate turbulence in the liquid when the filter medium is rotated, such turbulence tending to loosen the contaminating material collected on the filter medium and effect an auxiliary cleansing action thereof.

5. The apparatus of claim 4, wherein a plurality of filter medium and impervious annular members are provided with said turbulence generating means being disposed adjacent at least the outermost filter medium, taken relative to said axis of rotation.

6. The filter apparatus of claim 1, wherein said conduit means are formed integrally of the bottom disc means.

7. The apparatus of claim 1, wherein the filter medium comprises a cloth woven from monofilament fibers of tetrafluoroethylene to a thread count of about 92 by 90 per square inch.

8. The apparatus of claim 7, wherein turbulence-generating means are provided adjacent the filter medium whereby turbulence generated in the cooking liquid when the filter apparatus is rotated causes an auxiliary cleansing action on said filter medium.

9. The apparatus of claim 1, wherein the filter medium comprises a cloth woven from strands of a fluorinated ethylene resin.

10. The apparatus of claim 1, whErein the filter medium comprises a cloth woven from strands of a fluorinated propylene resin.

11. The apparatus of claim 1, wherein the filter medium comprises a felt-like mat structure made from fibers of materials having non-stick properties similar to that of a fluorinated ethylene resin.

12. The apparatus of claim 1, wherein the filter medium comprises a wire screen whose wires are coated with a material having non-stick properties similar to that of a fluorinated ethylene resin.

13. Filter apparatus suitable for removing contaminating material from hot cooking oil in a system of cooking food in said oil comprising: a filter surface in the form of a cloth woven from fibers selected from the group consisting of fluorinated ethylene and propylene resin, disposed symmetrically about an axis of rotation, said surface normally being at rest and being operable for filtering said material from the hot cooking oil; an annular member impervious to said liquid spaced inwardly of the filter surface relative to said axis; support elements in the form of top and bottom disc elements for supporting the filter surface and impervious annular member in spaced apart relation, said filter surface and annular member cooperating with said disc elements to define a closed receiving chamber for filtered cooking oil; conduit means carried by the bottom disc element and in communication with the receiving chamber for conveying the filtered oil therefrom; and, support means including bearing means, for rotatably supporting the filter surface, the annular member and the support elements, said support means being adapted to be selectively driven to effect periodic rotation of the filter surface about said axis, such rotation causing centrifugal forces to be generated which remove the filtered material from said filter surface, thereby enabling the latter to be cleaned centrifugally and otherwise left undisturbed.

14. The apparatus of claim 13, wherein turbulence generating means are provided adjacent the filter surface exteriorly thereof, the turbulence generating means being fixedly supported to cause turbulence in the cooking oil when the filter surface is rotating, whereby such turbulence tends to loosen the contaminating material collected on the filter surface and causes an auxiliary cleansing action on the same.

15. The apparatus of claim 13, wherein a plurality of filter surfaces and impervious annular members are provided, being supported by said disc elements in a manner forming a corresponding plurality of closed receiving chambers.

16. The apparatus of claim 15 wherein the innermost impervious annular member comprises a sealed cylinder that supports one filter surface and also minimizes the volume of cooking oil needed to fill a filter reservoir in which the filtering apparatus is housed.
