Description

Technical Field

[0001] The invention relates to the technical field of oil pressing, and in particular to a tea seed oil cold pressing processing device and a process thereof. Background Art

[0002] Tea seed oil is a product squeezed from the fruit of the oil-tea tree. Due to its low yield and rich nutritional value, tea seed oil is also known as "oil gold" and was used by the royal family in ancient times. With the maturity of the pressing process, tea seed oil began to be industrialized. The main production areas of tea seed oil are the Yangtze River Basin and the southwest. During the production process of tea seed oil, the oil-tea seeds need to be naturally dried first, and then the crude oil is squeezed out using a cold pressing device. After the crude oil is removed, the obtained oil is further processed.

[0003] A Chinese patent document with authorization announcement number CN221344505U discloses a vegetable oil cold pressing device. The vegetable oil cold pressing device is provided with a connecting plate and a motor. After use, the staff can push the oil receiving box to the back of the device through an electric slide, and then start the motor to drive the oil receiving box to flip ninety degrees as a whole, thereby preventing the oil receiving box from being always exposed to the air to prevent the oil subsequently received by the oil receiving box from being contaminated. By providing a sealing plate and a sealing strip, when in use, since the combined area of ​​the sealing plate and the sealing strip is larger than the oil receiving box, the sealing effect of the connecting oil box can be improved.

[0004] However, the structural design of the above-mentioned related technology is as follows: during the oil pressing process, the pressed tea seed oil contains more oil foam, and the oil foam is usually composed of bubbles and some suspended impurities. These bubbles and impurities are easy to block the pores of the filter screen or filter cloth when passing through the filter medium, resulting in a decrease in the filtration speed, thereby affecting the filtration efficiency.

[0005] Therefore, a tea seed oil cold pressing processing device and a process thereof are proposed to solve the above-mentioned problems. Summary of the invention

[0008] The oil pressing mechanism squeezes out the crude oil and then enters the collecting assembly. When the scraping assembly is able to scrape off the oil foam, it scrapes the oil foam into the foam storage assembly. The scraping assembly drives the transmission assembly to operate during the scraping process, and the transmission assembly drives the reciprocating screw to rotate. The reciprocating screw drives the piston plate on the slide cylinder to move up and down in the sealing box through the slide plate on the threaded block. During the upward movement of the piston plate, the foam storage assembly gradually opens and allows the oil foam to enter the sealing box. During the downward movement of the piston plate, the foam storage assembly gradually closes. When the foam storage assembly is completely closed, as the piston plate continues to move downward, the pressure in the sealing box gradually increases, thereby gradually breaking the oil foam.

[0009] Preferably, the collecting assembly comprises an oil storage tank, a baffle and two partitions, the oil storage tank is mounted on a base, the two partitions are mounted on one side of the baffle, and the height of the baffle is smaller than the height of the partition.

[0010] Preferably, the baffle is fixed to the inner wall of the oil storage tank, the partition is L-shaped, one side of two partitions are respectively installed on both sides of the inner wall of the oil storage tank, and an oil outlet pipe is installed at the bottom of the oil storage tank.

[0011] Preferably, the scraper assembly includes two groups of rotating parts, two transmission parts, multiple fixed rods and multiple scrapers, the two groups of rotating parts are respectively arranged on both sides of the interior of the oil storage tank, each group of the rotating parts includes two transmission wheels 1, the two transmission wheels 1 are symmetrically arranged and are respectively rotatably connected to both sides of the inner wall of the oil storage tank, two transmission wheels 1 in one group of rotating parts are respectively connected to two transmission wheels 1 in the other group of rotating parts through two transmission parts, the multiple fixed rods are evenly distributed between the two transmission parts along the trajectory of the transmission parts, the scrapers are installed on the outside of the fixed rods, and the scrapers are located between the two partitions.

[0012] The rotation of the transmission wheel 1 can drive the fixed rod to move along the track of the transmission member, thereby driving the scraper to move along the track of the scraper, so as to scrape the oil foam on the upper layer of the crude oil into the foam storage assembly for storage.

[0013] Preferably, a connecting rod 1 is installed between the two transmission wheels 1 in one group of rotating parts, one end of the connecting rod 1 is connected to the motor 2, and a connecting rod 2 connected to the transmission assembly is rotated between the two transmission wheels 1 in the other group of rotating parts.

[0015] The rotation of the transmission wheel 1 can drive the connecting rod 2 to rotate, and the connecting rod 2 drives the reciprocating screw on the worm wheel to rotate through the worm gear, so as to drive the piston plate to move up and down.

[0017] By providing the foam storage groove, the oil foam can be temporarily stored in the process of the piston plate moving downward, so as to prevent the oil foam from flowing onto the upper part of the piston plate.

[0018] Preferably, the foam blocking assembly includes a movable plate and a foam blocking plate, the movable plate having a horizontal portion and a vertical portion, the horizontal portion of the movable plate being elastically slidably connected in the slide groove along the vertical direction, the slide plate being located below the horizontal portion of the movable plate, the vertical portion of the movable plate being fixed to the foam blocking plate, and the foam blocking plate being located inside the foam storage tank and arranged close to the foam discharge port.

[0019] When the sliding plate moves upward, it can contact with the movable plate. As the sliding plate continues to move upward, it can drive the foam blocking plate to move upward to open the foam storage groove, so that the oil foam flows into the sealing box from the bottom of the piston plate. When the sliding plate moves upward, the movable plate gradually returns to its original position to close the foam storage groove and prevent the oil foam from flowing to the top of the piston plate.

[0020] A tea seed oil cold pressing process, using the tea seed oil cold pressing device, comprises the following steps: S1: The oil enters the oil pressing mechanism for cold pressing, and the squeezed oil enters the oil storage tank; S2: When the scraper can scrape off the oil foam, the motor 2 is started, and the multiple scrapers scrape the oil foam in the oil storage tank into the foam storage tank; S3: After the oil foam enters the sealing box, the reciprocating screw drives the slide plate to move downward through the threaded block, and the slide plate drives the piston plate to move downward through the slide cylinder to fractur the oil foam in the sealing box; S4: When the slide plate moves upward, the slide plate drives the foam blocking plate on the movable plate to move upward, thereby opening the foam discharge port, so that the oil foam in the foam storage tank enters the sealing box through the foam discharge port; S5: the defoamed oil enters an external filtering device for filtration to obtain crude oil; S6: The filtered crude oil is successively refined, degummed, washed, decolorized and deodorized to obtain refined tea seed oil.

[0021] The oil pressing mechanism squeezes out the crude oil and puts it into the oil storage tank. When the scraper can scrape off the oil foam, the scraper scrapes the oil foam into the foam storage tank. During the scraping process, the reciprocating screw drives the piston plate on the slide cylinder to move up and down in the sealing box through the slide plate on the threaded block. During the upward movement of the piston plate, the foam blocking plate moves up to allow the oil foam to enter the sealing box. During the downward movement of the piston plate, the foam blocking plate moves down and closes the foam storage tank. As the piston plate continues to move downward, the pressure in the sealing box gradually increases, causing the oil foam to gradually burst.

[0022] By adopting the above technical scheme, the beneficial effects of the present invention are as follows: the oil pressing mechanism squeezes out the crude oil and the crude oil enters the collecting assembly; when the scraping assembly is able to scrape off the oil foam, the scraping assembly scrapes the oil foam into the foam storage assembly; the scraping assembly drives the transmission assembly to operate during the scraping process; the transmission assembly drives the reciprocating screw to rotate; the reciprocating screw drives the piston plate on the slide cylinder to move up and down in the sealing box via the slide plate on the threaded block; during the upward movement of the piston plate, the foam storage assembly gradually opens and allows the oil foam to enter the sealing box; during the downward movement of the piston plate, the foam storage assembly gradually closes; when the foam storage assembly is completely closed, as the piston plate continues to move downward, the pressure in the sealing box gradually increases, thereby causing the oil foam to gradually break, so as to avoid affecting the filtering efficiency.

[0052] When the reciprocating screw 431 drives the slide plate 434 to move upward through the mounting rod 433 on the threaded block 432, the slide plate 434 can drive the foam blocking plate 454 on the movable plate 453 to move upward, thereby opening the foam discharge port 443.

When the slide plate 434 moves downward, the movable plate 453 drives the foam blocking plate 454 to reset to close the foam discharge port 443.

[0053] Working principle: When cold-pressing tea seed oil, the tea seed oil is discharged from the pressing chamber 23, and then flows into the oil storage tank 311 through the guidance of the guide hopper 29 and is located between the two partitions 312. As the tea seed oil continues to increase, the liquid level in the oil storage tank 311 continues to increase. When the scraper 344 can scrape off the oil foam, the motor 2 33 starts.

[0054] The motor 2 33 drives the transmission member 342 and the connecting rod 2 36 to rotate through the transmission wheel 1 341 . During the rotation process, the transmission member 342 drives the multiple fixed rods 343 to move around the trajectory of the transmission member 342 , thereby driving the scraper 344 to scrape the oil foam in the oil storage tank 311 into the foam storage tank 441 .

[0055] When the connecting rod 2 36 rotates, the connecting rod 2 36 drives the transmission wheel 3 461 to rotate through the transmission wheel 2 37 , and the transmission wheel 3 461 can drive the reciprocating screw 431 on the worm wheel 463 to rotate through the worm 462 .

[0056] When the reciprocating screw 431 rotates, the reciprocating screw 431 can drive the slide plate 434 to move up and down through the mounting rod 433 on the threaded block 432. When the slide plate 434 moves downward, the slide plate 434 drives the piston plate 436 to move downward through the slide cylinder 435. During the downward movement of the piston plate 436, the pressure in the sealing box 41 can be increased to fracture the oil foam in the sealing box 41, thereby achieving the effect of eliminating the oil foam. When the slide plate 434 moves upward, the slide plate 434 can drive the foam blocking plate 454 on the movable plate 453 to move upward, thereby opening the foam discharge port 443. At this time, the oil foam in the foam storage tank 441 enters the sealing box 41 through the foam discharge port 443.
