Description

Technical Field

[0001] The invention relates to the technical field of edible oil extraction, and in particular to an edible oil processing device. Background Art

[0002] Edible oil refers to animal or plant fats used in the food production process. It has the functions of heat conduction medium, improving color and taste, and increasing nutritional content. The processing of edible oil usually involves extracting oil from raw materials, such as soybeans, rapeseed, peanuts, corn, sunflower seeds, etc., and removing impurities and improving the quality of oil through a series of physical and chemical treatment processes, and finally obtaining oil suitable for human consumption. The selection of raw materials is usually screened, washed and dried, and then screening, airflow sorting and other methods are used to further remove impurities and break the oil seeds into smaller particles, which is conducive to the subsequent oil extraction. The main methods of oil extraction are pressing and solvent extraction. The specific method to be used depends on the type of raw materials and the required oil quality. Pressing is to directly squeeze oil from oil seeds through mechanical pressure. This method is suitable for harder oil seeds, such as peanuts, rapeseed, etc. Solvent extraction uses solvents, usually hexachloroene or hexane, to dissolve oil. After the oil and solvent are mixed, they are separated by evaporating the solvent. The solvent extraction method has a high oil yield and is suitable for large-scale production; the edible oil extraction processing equipment in the prior art is usually unable to achieve fully automatic oil extraction and has a low degree of automation.

A plurality of raised elastic sheets are arranged on the side transmission belt, and the raised elastic sheets are made of elastic material and cooperate with the side push plate.

[0008] The lower bevel gear rotates, and the upper bevel gear rotates through the vertical gear shaft, thereby driving the side bevel gear and the outer transmission wheel to rotate, and the outer wheel and the driving wheel rotate through the outer transmission belt. The driving wheel rotates and drives the conveyor belt to rotate, and the conveyor belt drives the driven wheel to rotate. The driven wheel rotates and drives the lower pulley to rotate, and cooperates with the upper pulley and the turning pulley to drive the side transmission belt to rotate; the raw materials are put into the feed hopper, and the raw materials fall onto the conveyor belt, and the conveyor belt moves the raw materials. The rotation of the side transmission belt will move with the raised elastic sheet on it, and the raised elastic sheet will push the side push plate to slide along the frame, thereby driving the upper pressure block to slide along the frame, and the transverse spring is stretched. When the upper pressure block moves to the rear The upper pressure block presses the front pressure block downward, and the front spring is compressed. At this time, the front pressure block that was originally pressed down by the upper pressure block rises and resets under the rebound of the front spring. When the side push plate moves to the limit position, the side transmission belt continues to move, and the raised elastic sheet is deformed under the action of the side push plate, so that the raised elastic sheet passes through the side push plate, and the side push plate is then reset under the rebound of the transverse spring. The upper pressure block presses the front pressure block downward, and the front spring is compressed. At this time, the rear spring rebounds, and the rear pressure block rises and resets. The raw materials that reach the bottom of the front and rear pressure blocks are preliminarily crushed by the reciprocating lifting of the rear pressure block and the front pressure block. At the same time, the lower support block provides support for the conveyor belt during crushing.

[0009] Furthermore, the extraction device includes an extraction pool fixedly installed under the frame, a bottom motor is arranged under the frame, the extraction pool is fixedly installed on the separation pool, holes are arranged on the bottom and sides of the extraction box, the extraction box is located above the extraction pool, a half-toothed gear is fixedly installed on the motor shaft of the bottom motor, a left gear is rotatably installed on the separation pool, a pinion gear is fixedly installed on the left gear, a right gear is rotatably installed on the separation pool, a right bevel gear is fixedly installed on the right gear, the half-toothed gear is meshed with the pinion gear, the left gear is meshed with the right gear, and the right bevel gear is meshed with the lower bevel gear.

A bidirectional screw is rotatably installed on the internal threaded sleeve, and a convex ball on the inner wall of the internal threaded sleeve slides in the bidirectional external thread of the bidirectional screw. A screw gear is fixedly installed on the bidirectional screw, and the screw gear is meshed with the gear column. A rotating block is rotatably installed on the end of the bidirectional screw, and an inner push plate is slidably installed on the rotating block. The inner bottom surface of the extraction pool is a slope, and the inner push plate slides along the slope inside the extraction pool.

[0011] Furthermore, a liquid outlet trough is arranged on the slope of the bottom surface of the extraction tank, and liquid outlet pipes are arranged on both sides of the extraction tank, and the liquid outlet pipes are connected to the liquid outlet trough.

[0012] The raw materials after preliminary crushing fall into the extraction box through the conveyor belt, and the solvent is passed into the extraction pool through the separation device. The bottom motor rotates to drive the half-tooth gear to rotate, and the half-tooth gear drives the small gear and the left gear to rotate intermittently, thereby driving the right gear and the middle gear to rotate intermittently, thereby driving the lower bevel gear to rotate through the right bevel gear, and the middle gear drives the gear column to rotate, and the gear column drives the screw gear and the bidirectional screw to rotate. Under the action of the convex ball in the internal thread sleeve, the bidirectional screw and the screw gear spirally move forward, thereby driving the inner push plate along the bottom slope of the extraction pool through the rotating block. The inner push plate slides on the surface, and pushes the solvent entering the extraction pool toward the extraction box through the inner push plate. When the inner push plate reaches the left side of the liquid outlet slot, the liquid in the extraction pool cannot flow out of the liquid outlet slot, and as the inner push plate moves, the liquid level in the extraction pool will become higher and higher, and the solvent will contact the raw material in the extraction box. At this time, the half-tooth gear is disengaged from the pinion gear, and the inner push plate stops moving. The raw material is extracted by the solvent. When the half-tooth gear is engaged with the pinion gear again, it will drive the inner push plate back to the initial position. At this time, the extracted liquid flows into the separation pool through the liquid outlet slot and the liquid outlet pipe.

Under the action of the convex ball in the internal threaded sleeve 216, the bidirectional screw 212 and the screw gear 213 spirally move forward, thereby sliding along the bottom slope of the extraction tank 203 with the inner push plate 214 through the rotating block 217, and passing The solvent entering the extraction pool 203 is pushed toward the extraction box 201 by the inner push plate 214. When the inner push plate 214 reaches the left side of the liquid outlet trough 215, the liquid in the extraction pool 203 cannot flow out of the liquid outlet trough 215, and as the inner push plate 214 moves, the liquid level in the extraction pool 203 will become higher and higher, and the solvent will contact the raw material in the extraction box 201. At this time, the half-toothed gear 205 is disengaged from the pinion 206, and the inner push plate 214 stops moving. The raw material is extracted by the solvent. When the half-toothed gear 205 is meshed with the pinion 206 again, it will drive the inner push plate 214 to return to the initial position. At this time, the extracted liquid flows into the separation pool 301 through the liquid outlet trough 215 and the liquid outlet pipe 204. The solvent in the solvent tank 302 is pumped into the liquid inlet pipe 303 through the pump in the solvent tank 302, and then enters the extraction tank 201; the extracted liquid flowing out from the liquid outlet pipe 204 flows out to the separation tank 301 through the liquid return pipe 304 and the upper bend pipe 307, and the upper bend pipe 307 faces upward to prevent the solvent vapor from flowing back. The heating pipe in the separation tank 301 heats the liquid in the separation tank 301 to evaporate the solvent, and the solvent vapor is discharged along the return vapor pipe 305. The cooling pipe 306 cools the vapor, and finally the solvent returns to the solvent tank 302.
