[0002] Daoputan pickled vegetables are a favorite dish of Chinese families. They are pickled with salt and other seasonings for a certain period of time. They have a strong salty taste and can be preserved for a long time. The main raw materials are peppers, various vegetables, and salt. The main production process is washing, cutting, pickling, drying, and fermentation in jars.

[0003] The Chinese patent application number 202223574282.5 discloses "a dehydration device for pickle production, including a dehydration chamber, a dryer, and a collection chamber. The dryer is connected to the dehydration chamber, the lower part of the dehydration chamber is connected to the collection chamber, the lower part of the dehydration chamber is provided with a slag discharge valve, one end of the collection chamber is also provided with a clean water tank, and the collection chamber is connected to the clean water tank through a filter. The advantage of the utility model is that after the centrifugal dehydration is completed, the dryer is started, the drying motor drives the fan blades to rotate to generate an upward airflow, the airflow conducts heat to the air duct through the electric heating wire, and the air duct uses the hot air to cause the dehydration chamber to further quickly dry the pickles, thereby reducing the dehydration time of the pickles and improving the production efficiency of the pickles."

[0018] S2, then drive the extrusion plate down through the hydraulic device, so that the extrusion plate enters the loading trough, squeezes the pickles through the extrusion plate to dehydrate the pickles, and drives the connecting frame down through the extrusion plate, so that the lifting rod is lowered accordingly. During the descending process of the lifting rod, when the movable teeth contact the third gear, the movable teeth are squeezed into the first tooth groove by the third gear.

When the bottom cover closes the bottom end of the water collecting hopper, the vacuum pump is started to quickly extract the air in the water collecting hopper through the vacuum pipe and then discharge it through the exhaust pipe, so that negative pressure is quickly formed in the water collecting hopper, so that the water in the loading trough is sucked into the water collecting hopper, further improving the dehydration effect, and the salt water flowing out of the water collecting hopper is collected by the water collecting trough;

At this time, the lifting rod rises, and the movable teeth are engaged with the third gear. The third gear drives the rotating shaft to rotate, so that the turning rod rotates accordingly. The pickles in the loading trough are stirred by the rotating turning rod, and the placement state of the squeezed pickles is adjusted.

7. The extrusion dehydration device for pickle processing according to claim 6, characterized in that: The water collecting mechanism (6) comprises a threaded barrel (607), a translation frame (608), a fourth gear (610) and a water collecting trough (611). There are two threaded barrels (607) and they are respectively connected to two second threaded rods (606) through threads. The top of the translation frame (608) is fixedly mounted on the bottom ends of the two threaded barrels (607) by bolts. The bottom cover (609) is fixedly mounted in the middle of the bottom end of the translation frame (608) by bolts. The fourth gear (610) is fixedly mounted on the front end of the second threaded rod (606) by bolts. The water collecting trough (611) is installed at the bottom end of the housing (1) by insertion. The second tooth groove (505) is connected to the fourth gear (610) by meshing.

8. A method for processing pickled vegetables according to any one of claims 1 to 7, characterized in that: The following steps are involved: S1, starting the motor (205), driving the first gear (206) to rotate through the motor (205), when the first gear (206) rotates, driving the first threaded rod (207) to rotate through the second gear (208), and making the two first threaded rods (207) rotate simultaneously through the transmission belt (209), at this time, driving the loading trough (203) to move outside the housing (1) through the translation block (210), after the loading trough (203) moves outside the housing (1), the radish pickles to be squeezed and dehydrated are loaded into the loading trough (203), and then controlling the motor (205) to rotate in the opposite direction, so that the loading trough (203) moves to the top of the drainage port (202); S2, then the hydraulic device (3) drives the squeezing plate (4) to descend, so that the squeezing plate (4) enters the loading trough (203), and the pickles are squeezed by the squeezing plate (4) to dehydrate the pickles, and the squeezing plate (4) drives the connecting frame (501) to descend, so that the lifting rod (502) is lowered accordingly. During the descending process of the lifting rod (502), when the movable tooth (504) contacts the third gear (508), the movable tooth (504) is squeezed into the first tooth groove (503) by the third gear (508), and at this time, the movable tooth (504) is not in contact with the third gear. (508) is meshed, and when the second tooth groove (505) contacts the fourth gear (610), the fourth gear (610) is driven to rotate by the second tooth groove (505), so that the second threaded rod (606) rotates following the fourth gear (610). When the fourth gear (610) rotates, the translation frame (608) is driven to move in the direction of the fourth gear (610) by the threaded cylinder (607), and the bottom cover (609) is driven to translate to the bottom end of the water collecting bucket (602) by the translation frame (608), and the bottom end of the water collecting bucket (602) is closed by the bottom cover (609); S3. Before the bottom end of the water collecting bucket (602) is closed by the bottom cover (609), the pickles in the loading trough (203) are squeezed to release a large amount of water, but a large amount of water still remains in the gaps between the pickles in the loading trough (203). When the bottom cover (609) closes the bottom end of the water collecting bucket (602), the vacuum pump (604) is started to quickly extract the air in the water collecting bucket (602) through the vacuum pipe (603) and then discharge it through the exhaust pipe (605), so that negative pressure is quickly formed in the water collecting bucket (602), so that the water in the loading trough (203) is sucked into the water collecting bucket (602), further improving the dehydration effect, and the salt water flowing out of the water collecting bucket (602) is collected through the water collecting trough (611); S4. After squeezing once, in order to ensure the dehydration effect, the squeezing plate (4) is driven to move upward by the hydraulic device (3). At this time, the lifting rod (502) rises, and the movable teeth (504) are meshed with the third gear (508). The third gear (508) drives the rotating shaft (506) to rotate, so that the turning rod (507) rotates accordingly. The pickled vegetables in the loading trough (203) are stirred by the rotating turning rod (507), and the placement state of the squeezed pickled vegetables is adjusted. Then, the hydraulic device (3) is controlled to start squeezing again, thereby improving the dehydration efficiency.
