TECHNICAL FIELD

[0001] The utility model relates to the technical field of grease refining, particularly to a filter press for low-temperature grease refining. BACKGROUND

[0002] Low-temperature grease refers to the grease that can keep stable liquid state at low temperature, such as fish oil. Low-temperature grease is not suitable for high-temperature cooking because it is rich in unsaturated fatty acids and prone to oxidation and deterioration. Low-temperature grease is generally used for seasoning and making cold dishes such as fresh vegetable salad.

[0003] When refining low-temperature grease, filtration is required. However, the ordinary filtration equipment has poor filtering effect on grease, and the grease is not easy to be completely refined. Using a filter press is not convenient for feeding and discharging raw materials and residues, which affects the processing efficiency. Therefore, the present application provides a filter press for low-temperature grease refining to solve the above problems. SUMMARY

[0004] The utility model discloses a filter press for low-temperature grease refining, which overcomes the shortcomings of the prior art.

[0005] The utility model discloses a filter press for low-temperature grease refining, which overcomes the shortcomings of the prior art.

[0006] Optionally, the two ends of the filter press are closed by end plates, and the two long hydraulic rods are installed on the two end plates, respectively. Support legs are installed at the four corners of the bottom surface of the filter press for supporting.

[0007] Optionally, a fixed plate is installed at the middle of the inside of the feeding cylinder, and telescopic cylinders are installed at the two ends of the top surface of the fixed plate. The lifting seal seat is installed at the output ends of the two telescopic cylinders. The size of the lifting seal seat is adapted to the size of the inside of the feeding cylinder. The two sides of the outside of the lifting seal seat are bent downward.

[0008] Optionally, the upper part of the air cavity is closed by a cover plate, and the air pipe penetrates through the fixed plate and is in sliding fit with the fixed plate.

[0009] Optionally, the wedge angle of the wedge block is an acute angle, and a plurality of mounting holes in uniform array are formed on both sides of the interior of the air cavity, and a plurality of air nozzles are respectively mounted in the mounting holes.

[0010] The utility model has the following advantages:

A filter plate is arranged above the discharge oil cylinder. Raw materials are fed into the filter press box from the feeding cylinder, and the two pressing plates can extrude the raw materials, so that the grease can be filtered by the filter plate and discharged from the discharge oil cylinder for collection, and the residues after extrusion can be discharged from the discharge cylinders, so as to facilitate the staff to centrally process the residues in the later period.

[0012] The lifting sealing seat driven by the telescopic air cylinder moves up and down in the feeding cylinder, and the two sides are downwardly inclined. When the raw materials are fed from the feeding cylinder, the raw materials can slide down along the lifting sealing seat, and when the lifting sealing seat rises, the feeding cylinder can be closed, so as to facilitate the extrusion of the raw materials and avoid the raw materials from overflowing.

[0013] The wedge block is formed on the middle below the lifting sealing seat and is hollow to form an air cavity. A plurality of mounting holes are formed on both sides of the exterior of the air cavity, and an air nozzle is arranged in the air cavity. An air pipe is arranged above the air cavity, and an air valve is arranged at the outer end of the air pipe. High-pressure gas is filled into the air cavity. When the residues are cleaned, the wedge block divides the residues into two halves, the high-pressure gas can be blown out from the air nozzle, and the residues can be blown into the discharge cylinder, so as to facilitate the cleaning and collection of the residues.
