Description

Technical Field

[0001] This invention relates to the field of pre-cut vegetable processing technology and equipment, specifically to a cleaning device and its cleaning method used in the cleaning process of a fresh-cut vegetable processing line. Background Technology

[0002] With the improvement of people's living standards and the acceleration of their pace of life, people have increasingly higher requirements for the practicality and convenience of food. Fresh-cut vegetables, also known as pre-cut vegetables, refer to lightly processed vegetable products made from fresh vegetables after sorting, washing, cutting, and processing, and then packaging them. This saves people the tedious and time-consuming work of sorting, washing, and cutting vegetables while maintaining the freshness of the ingredients, allowing them to be cooked or eaten directly. Fresh-cut vegetables retain their original freshness while being processed to ensure cleanliness and hygiene, making them ready to eat and meeting people's needs for convenience and a fast-paced lifestyle. Relying on manufacturers' low-temperature transportation and supermarket refrigerated display cases, large and medium-sized supermarkets have established counters for selling fresh-cut vegetables. After sorting and cutting, fresh-cut vegetable processing lines require washing, and current washing methods generally include soaking and rinsing. Soaking and washing involve thorough contact with vegetables, but the cleaning power is weak and it is difficult to completely remove dirt, impurities, and hair adhering to the vegetables. Rinsing, on the other hand, has a strong effect on vegetables, but under large-scale processing and production conditions, the rinsing water flow often only acts on a local area of ​​the vegetables and is difficult to fully contact all surfaces of the vegetables. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the cleaning effect of soaking and rinsing in the existing cleaning process of fresh-cut vegetables, and to provide a processing device and method for fresh-cut vegetables that combines soaking and rinsing to achieve strong cleaning of all surfaces of vegetables, thereby improving the processing effect and work efficiency of the cleaning process.

[0004] This fresh-cut vegetable processing device and method includes a frame and a washing tank mounted on the frame. Following the direction of vegetable material transport, the washing tank sequentially includes a low-level immersion tank, a lifting section, and a high-level rinsing section. The immersion tank and rinsing section are connected by the lifting section. The washing tank contains a multi-section conveying mechanism for transporting vegetable materials. The immersion tank is an inverted trapezoidal tank body, equipped with a circulating bubble immersion mechanism and a swing rinsing mechanism. The rinsing section has a U-shaped cross-section, with a tumbling and rotating rinsing mechanism on the upstream side and a vibrating draining and discharge mechanism on the downstream side. The circulating bubble immersion mechanism includes a first circulating pump that draws water from the downstream side of the immersion tank to the upstream side to form a circulating water flow, and a vortex fan that supplies high-pressure air to the bottom of the immersion tank, generating a large number of bubbles in the immersion water and causing the water flow to tumble. The swing rinsing mechanism includes a mechanism that reciprocates above the immersion tank and swings inwards to change direction while rinsing. The system includes a swiveling flushing assembly and a second circulating pump that draws water from the downstream side of the immersion washing tank to the swiveling flushing assembly; the tumbling and rotating flushing mechanism includes a roller assembly for tumbling and slowly conveying the vegetable material forward, and a swirl flushing assembly that rotates and moves above the roller assembly to vertically flush the tumbling vegetable material with high-pressure water; the vibrating draining and discharging mechanism includes an inclined permeable mesh plate and a vibrating motor that drives the permeable mesh plate to vibrate up and down and outputs the vegetable material while completing the draining; the multi-segment conveying mechanism is a conveying line composed of a scraper conveyor installed in the immersion washing tank and the lifting section, and the roller assembly and permeable mesh plate on the flushing position, which realizes the material conveying of vegetable material from the feed to the discharge, wherein the frame and the scraper conveyor are provided with L-shaped track pressure plates on both sides to limit the travel path of the scraper conveyor's mesh belt, and a gap is left between the vertical surface of the L-shaped track pressure plate and the inner wall of the immersion washing tank, and a large number of isolation holes are provided on the vertical surface.

[0005] Furthermore, the frame is provided with side frames on both sides, and lead screws and guide rods are respectively provided on the side frames; the swing punch assembly includes a pair of slides, three swing punch tubes rotatably connected between the two slides, support arms for connecting the swing punch tubes to the slides, and connecting arms for connecting the swing punch tubes. A row of high-pressure nozzles a is fixedly installed on each swing punch tube; wherein, one side slide is threaded to the lead screw, and the other side slide is slidably fitted onto the guide rod; one end of the support arm is fixedly connected to one end of the swing punch tube, and the other end of the support arm is hinged to the slide; the two ends of the connecting arm are respectively hinged to two adjacent support arms.

[0006] Furthermore, a reciprocating motor is provided on the frame on the side where the lead screw is located, and a swing electric cylinder is provided on the slide on the side where the lead screw is located. The output shaft of the reciprocating motor is fixedly connected to the side where the lead screw is located. The cylinder rod of the swing electric cylinder is connected to the nearest end of the swing punch tube through a drive arm. The two ends of the drive arm are respectively connected to the nearest end of the swing punch tube and the end of the cylinder rod of the swing electric cylinder.

[0007] Furthermore, the roller assembly includes five conveyor rollers rotatably connected to the side wall of the rinsing position. The five conveyor rollers are arranged in a staggered manner at different heights, and the second and fourth conveyor rollers are covered with frosted rubber sleeves.

[0008] Furthermore, a tumbling conveyor reducer is provided on the outer side of the flushing position sidewall. One end of the conveyor roller extends out of the flushing position sidewall and is provided with a sprocket at the extending end. The output shaft of the tumbling conveyor reducer is connected to the sprocket closest to the conveyor roller. The sprockets of the conveyor rollers are connected in sequence by a transmission belt.

[0009] Furthermore, the rotary flushing assembly includes a support platform on both sides of the flushing position, a lower bearing mounted on the support platform, a crank arm fixed on the inner ring of the lower bearing, an upper bearing mounted on the upper end of the crank arm, a pipe rack fixed on the inner ring of the upper bearing, rotary flushing pipes mounted on the pipe racks on both sides, and a row of high-pressure nozzles b fixedly mounted on each rotary flushing pipe.

[0010] Furthermore, a rotary flushing reducer is provided on the outer side of the flushing position sidewall, a drive gear is provided on the output shaft of the rotary flushing reducer, a pulley is provided at the lower part of the crank arm, and a driven gear that meshes with the drive gear is provided above the pulley on the crank arm closest to the rotary flushing reducer. The pulleys of the crank arm are connected in sequence by a transmission belt.

[0011] Furthermore, a balancing mesh frame for fixing the permeable mesh plate is installed on the output shaft of the oscillating motor. The balancing mesh frame includes a base connected to the output shaft of the oscillating motor, a U-shaped support frame for installing the permeable mesh plate, and a spring telescopic rod connected between the base and the U-shaped support frame. The bottom plate of the U-shaped support frame is inclined inward to return the water drained from the vegetable material to the washing pool.

[0012] Furthermore, the second circulating pump draws water from the downstream side of the immersion tank and delivers it to each of the swirling pipes of the swirling assembly. The frame is equipped with a clean water tank for connecting to an external clean water source to replenish / replace water in the immersion tank, a clean water delivery pump for pumping water from the clean water tank to each of the swirling pipes of the swirling assembly, and a control cabinet and power distribution cabinet for centrally controlling and driving the operation of each motor, electric cylinder and pump body.

[0013] The processing method of this fresh-cut vegetable processing device includes the following steps:

[0014] S1 - The chopped vegetable material is fed into the left side of the washing tank and slides down the left slope of the inverted trapezoidal immersion tank onto the mesh belt of the scraper conveyor. Under the action of the scraper conveyor and the circulating water in the tank, it is conveyed forward. Under the turbulent water flow formed by the bubbles, the material is mainly in a floating state in the immersion tank and is constantly being washed by the water sprayed at different angles by the swing flushing component. The material is constantly pressed down to the water surface, then floated up again, moved forward, and then moved backward, thus achieving a thorough soaking of the vegetable material and cleaning the mud and impurities off the material. During the water circulation process, the perforated plates on both sides can prevent the gradually deposited mud and sand impurities from re-entering the washing area above the immersion tank in large quantities.

[0015] S2 - After immersion washing is completed, the material is lifted by the scraper conveyor at the lifting section and the immersion water is drained.

[0016] S3 - The material is discharged to the roller assembly. Five rollers arranged at different heights in the roller assembly work together to transport and tumble the material. The two rough rollers in the middle and lower position raise the material to achieve the tumbling range (if all rollers are smooth, the tumbling range will be insufficient; if all rollers are rough, the conveying speed will be too fast and the material will be crushed between adjacent rollers). During this process, the swirl jet component above the rollers continuously flushes downwards and changes position, using clean water to perform a secondary cleaning of the vegetable material. Due to the change in position, the high-pressure water can more comprehensively clean all parts of the material. Firstly, it does not affect the overall material conveying (high-pressure water in a fixed position will affect the conveying speed of the material in the directly opposite part due to the downward pressure, causing local accumulation, while other areas will not receive high-pressure washing). Secondly, the direct jet coverage area is comprehensive and uniform.

[0017] After the S4-swirl flushing is completed, the material is discharged onto the permeable mesh plate. The inclined permeable mesh plate, driven by the reciprocating motion of the vibrating motor and buffered by the balanced mesh frame, generates adjustable oscillations through springs of appropriate hardness. The spring hardness can be selected according to the type of vegetable, its cut shape, and the amount of water it covers. Simultaneously, the spring length is selected according to the required conveying speed to adjust the inclination of the mesh plate. The material is discharged while draining water, completing the entire cleaning process. This invention provides a processing device and method for fresh-cut vegetables, overcoming the shortcomings of existing fresh-cut vegetable cleaning processes that rely solely on soaking and rinsing. By combining these two methods, it achieves strong cleaning of all surfaces of the vegetables, thereby improving the processing effect and work efficiency of the cleaning process.

The frame 1 and the scraper conveyor 31 are provided with L-shaped track pressure plates 311 on both sides to limit the travel path of the mesh belt of the scraper conveyor 31. A gap is left between the vertical surface of the L-shaped track pressure plate 311 and the inner wall of the immersion tank 21, and a large number of isolation holes 312 are arranged on the vertical surface.

[0035] Example 2: As Figures 1 to 3As shown, the processing device for fresh-cut vegetables has side frames 11 on both sides of the frame 1, and a lead screw 111 and a guide rod 112 are respectively provided on the side frames 11. The swing-flush assembly 51 includes a pair of slides 511, three swing-flush tubes 512 rotatably connected between the two slides 511, a support arm 513 for connecting the swing-flush tubes 512 to the slides 511, and a connecting arm 514 for connecting the swing-flush tubes 512.

Among them, one side slide 511 is threaded to the lead screw 111, and the other side slide is slidably fitted onto the guide rod 112. One end of the support arm 513 is fixedly connected to one end of the swing-flush tube 512, and the other end of the support arm 513 is hinged to the slide 511. The two ends of the connecting arm 514 are respectively hinged to the two adjacent support arms 513.

The two ends of the drive arm 541 are respectively connected to one end of the nearest swing jet pipe 512 and the end of the cylinder rod of the swing cylinder 54. With this design, the reciprocating motion of the cylinder rod of the swing cylinder, through the transmission command of the drive arm and connecting arm, pushes and pulls the support arm to swing left and right, and the high-pressure nozzle moves in a fan-shaped arc with the swing jet pipe. This, in conjunction with the lead screw mechanism, drives the slide to move back and forth, spraying the vegetable material floating on the water surface in the immersion tank back and forth with changing angles. The remaining structures and components are as described in Embodiment 1 and will not be repeated.

[0036] Example 3: As Figures 1 to 3As shown, the roller assembly 61 of this fresh-cut vegetable processing device includes five conveyor rollers 611 rotatably connected to the side wall of the rinsing position 23. The five conveyor rollers 611 are arranged in a staggered manner at different heights. The second and fourth conveyor rollers 611 are covered with frosted rubber sleeves 612. A tumbling conveyor reducer 63 is provided on the outer side of the side wall of the rinsing position 23. One end of each conveyor roller 611 extends out of the side wall of the rinsing position 23, and a sprocket 613 is provided at the protruding end. The output shaft of the tumbling conveyor reducer 63 is connected to the sprocket 613 closest to the conveyor roller 611.

With this design, the tumbling conveyor reducer drives the conveyor rollers to rotate, turning and conveying the vegetable material delivered by the scraper conveyor, and receiving high-pressure water jets from the upper rotary spray assembly for secondary cleaning. The rotary flushing assembly 62 includes a support platform 621 on both side walls of the flushing position 23, a lower bearing 622 mounted on the support platform 621, a crank arm 623 fixed on the inner ring of the lower bearing 622, an upper bearing 624 mounted on the upper end of the crank arm 623, a pipe bracket 625 fixed on the inner ring of the upper bearing 624, and rotary flushing pipes 626 mounted on the pipe brackets 625 on both sides.

[0037] Example 4: Figures 1 to 3As shown, the processing device for fresh-cut vegetables has a balancing mesh frame 73 mounted on the output shaft of the vibrating motor 72 for fixing the permeable mesh plate 71. The balancing mesh frame 73 includes a base 731 connected to the output shaft of the vibrating motor 72, a U-shaped support frame 732 for mounting the permeable mesh plate 71, and a spring telescopic rod 733 connecting the base 731 and the U-shaped support frame 732. The bottom plate of the U-shaped support frame 732 is inclined inward to return the water drained from the vegetable material to the washing tank. Under the reciprocating drive of the vibrating motor and the buffer of the balancing mesh frame, the inclined permeable mesh plate forms an adjustable vibration by selecting a spring of appropriate hardness. The spring hardness can be selected according to the type of vegetable, the cut shape, and the amount of water coverage. At the same time, the spring length is selected according to the conveying speed requirements to adjust the inclination of the mesh plate, so that the material is output while draining water, completing the entire washing process. The inwardly inclined U-shaped support frame base returns the water drained from the vegetable material to the washing tank, where it is finally combined with the swirling water and flows back to the soaking tank, ensuring that the discharged material is relatively dry while reducing the consumption of washing water. The remaining structures and components are as described in Embodiment 1 and will not be described again.

[0038] Example 5: Figures 1 to 3 As shown, in this fresh-cut vegetable processing device, the second circulation pump 52 draws water from the downstream side of the immersion tank 21 and delivers it to each of the oscillating pipes 512 of the oscillating assembly 51. The frame is equipped with a clean water tank 12 for connecting to an external clean water source to replenish / replace water in the immersion tank 21, a clean water delivery pump 13 for pumping water from the clean water tank 12 to each of the swirl pipes 626 of the swirl assembly 62, and a control cabinet and distribution cabinet 14 for centrally controlling and driving the operation of each motor, cylinder, and pump. The second circulation pump and the clean water delivery pump are connected to the oscillating and swirl pipes via high-pressure resistant hoses, completing water delivery without restricting the movement of the nozzles. The hoses in the attached diagram are only for illustrating the hose connection relationship; in the actual product, most sections of the hoses are constricted and fixed to the frame and the side wall of the immersion tank. The remaining structures and components are as described in Embodiment 1 and will not be repeated.

[0039] Implementation Method 1: Processing Method of the Fresh-Cut Vegetable Processing Device The fresh-cut vegetable processing device described in the above embodiments includes the following steps:

[0040] S1 - The chopped vegetable material is fed into the left side of the washing tank and slides down the left slope of the inverted trapezoidal immersion tank onto the mesh belt of the scraper conveyor.

During the water circulation process, the perforated plates on both sides can prevent the gradually deposited mud and sand impurities from re-entering the washing area above the immersion tank in large quantities.

[0041] S2 - After immersion washing is completed, the material is lifted by the scraper conveyor at the lifting section and the immersion water is drained.

[0042] S3 - The material is discharged to the roller assembly. Five rollers arranged at different heights in the roller assembly work together to transport and tumble the material. The two rough rollers in the middle and lower position raise the material to achieve the tumbling range (if all rollers are smooth, the tumbling range will be insufficient; if all rollers are rough, the conveying speed will be too fast and the material will be crushed between adjacent rollers).

The inclined permeable mesh plate, driven by the reciprocating motor and buffered by the equalizing mesh frame, forms an adjustable oscillation by selecting a spring with appropriate hardness. The spring hardness can be selected according to the type of vegetable, the cut shape, and the amount of water. At the same time, the spring length is selected according to the conveying and discharge speed requirements to adjust the inclination of the mesh plate. The material is discharged while draining water, completing the entire cleaning process.

[0044] This fresh-cut vegetable processing device and method overcome the shortcomings of existing fresh-cut vegetable processing methods, which rely on soaking and rinsing respectively. By combining soaking and rinsing, it can achieve strong cleaning of all surfaces of vegetables, thereby improving the processing effect and work efficiency of the cleaning process.
