Description

Technical Field

[0001] The present invention relates to the technical field of daylily processing, and particularly to a pre-cooling device and a pre-cooling method for daylily food processing. Background Technique

[0002] Precooling refers to the operation process of rapidly reducing the temperature of picked fruits, vegetables and freshly produced foods to the process requirement temperature by using low-temperature treatment methods. The pre-cooled agricultural products not only have high quality, which is beneficial to preventing quality loss during storage, but also reduce the cooling load of facilities and equipment such as refrigerated trucks, refrigerated ships and cold storages, realizing the energy-saving operation of refrigeration, storage and transportation devices. After the daylily food processing is completed, it usually also needs to be pre-cooled to facilitate its subsequent transportation and ensure its freshness.

[0003] However, the existing pre-cooling equipment for daylily food processing usually adopts the air-cooling method. Although this method can realize the pre-cooling treatment of daylilies, it has the problems of slow cooling efficiency and low energy conversion rate. Moreover, since daylilies are generally stacked on the conveyor belt after processing, the area of daylilies receiving cold air treatment is small, and the cold air treatment cannot be carried out comprehensively. In addition, the residual moisture of daylilies will affect the subsequent processing. Summary of the Invention

[0013] The present invention also discloses a pre-cooling method for processing daylily food. The pre-cooling method of the pre-cooling equipment for processing daylily food includes the following steps: Step 1: Place the processed daylilies on the outer wall of the leaky hole conveyor belt. Start the motor. The motor drives the rotating shaft to rotate. The rotating shaft drives the shaft sleeve to rotate. The shaft sleeve drives the leaky hole conveyor belt to rotate. Start the telescopic rod. The telescopic rod drives the tooth block sleeve to move up and down. Restricted by the positioning of the limiting rod, when the tooth block sleeve moves up and down, it drives the irregular tooth sleeve plate to rotate. When the irregular tooth sleeve plate rotates, it drives the rotating bar to rotate. Restricted by the round rod, the rotating bar drives the round plate to rotate. The round plate drives the round sleeve shell to rotate. The round sleeve shell drives the rubber tooth plate to rotate; Step 2: The telescopic rod drives the pressing box to move up and down. The pressing box drives the sponge plate to descend. The tooth block sleeve drives the square plate to move up and down. The square plate drives the connecting rod to move up and down. Under the limitation of the track hole, the connecting rod drives the pressing plate to move up and down. When the pressing plate falls, the air flow inside the condensation box moves out through the air discharge pipe. At the same time, when the pressing plate falls, the elastic cord is stretched. During the stretching process of the elastic cord, it drives the sliding plate to move inside the pressing box. The sliding plate drives the cross plate to move. The cross plate drives the scraping plate to move; Step 3: During the rotation of the rubber tooth plate, it comes into contact with the daylily, causing the rubber tooth plate to slide on the outer wall surface of the circular sleeve housing. The rubber tooth plate drives the arc-shaped plate to move, the arc-shaped plate drives the flexible rope to move, the flexible rope is stretched, the flexible rope drives the special-shaped scraper to rotate. At the same time, during the rotation of the circular sleeve housing, it drives the suction fan to rotate. The suction fan generates negative pressure, and the negative pressure absorbs the cold air inside the condensation box into the interior of the circular sleeve housing through the elbow pipe. The cold air enters the interior of the arc-shaped box through the air pipe, and the cold air enters the interior of the exhaust pipe through the arc-shaped box.

[0014] The present invention has the following beneficial effects: In the present invention, the processed daylilies are placed on the outer wall of the perforated conveyor belt. The motor is started, and the motor drives the rotating shaft to rotate. The rotating shaft drives the sleeve to rotate, and the sleeve drives the perforated conveyor belt to rotate. The telescopic rod is started, and the telescopic rod drives the tooth block sleeve to move up and down. Restricted by the positioning of the limiting rod, when the tooth block sleeve moves up and down, it drives the irregular tooth sleeve plate to rotate. When the irregular tooth sleeve plate rotates, it drives the rotating bar to rotate. Restricted by the round rod, the rotating bar drives the round plate to rotate. The round plate drives the circular sleeve housing to rotate, and the circular sleeve housing drives the rubber tooth plate to rotate. During the rotation of the rubber tooth plate, the piled-up daylilies are turned over, so that the daylilies are no longer piled up, and the daylilies can stay on the outer wall of the perforated conveyor belt in a more dispersed manner, expanding the contact area between the daylilies and the cold air and improving the pre-cooling efficiency of the daylilies.

[0015] (2) In the present invention, when the rubber tooth plate comes into contact with the daylily during rotation, it will drive the daylily up. Due to the self-weight of the daylily, the rubber tooth plate slides on the outer wall surface of the circular sleeve housing. The rubber tooth plate drives the arc-shaped plate to move, the arc-shaped plate drives the flexible rope to move, the flexible rope is stretched, and the flexible rope drives the special-shaped scraper to rotate. During the rotation of the special-shaped scraper, the daylilies hanging on the rubber tooth plate can be cleaned, preventing the daylilies from adhering to the rubber tooth plate. At the same time, during the rotation of the circular sleeve housing, it drives the suction fan to rotate. The suction fan generates negative pressure, and the negative pressure absorbs the cold air inside the condensation box into the interior of the circular sleeve housing through the elbow pipe. The cold air enters the interior of the arc-shaped box through the air pipe, and the cold air enters the interior of the exhaust pipe through the arc-shaped box. The cold air blows towards the daylilies on the rubber tooth plate through the exhaust pipe, further preventing the daylilies.

[0016] (3) In the present invention, the telescopic rod drives the pressing box to move up and down. The pressing box drives the sponge board to descend, so that the sponge board compresses the daylily, reducing the moisture inherent in the daylily. The tooth block sleeve drives the square plate to move up and down, and the square plate drives the connecting rod to move up and down. Under the limitation of the track hole, the connecting rod drives the extrusion plate to move up and down. When the extrusion plate falls, the air flow inside the condensation box moves outwards through the air discharge pipe, thereby pre-cooling the daylily on the top of the perforated conveyor belt. And due to the setting of the sealing strip, it prevents the cold air from leaking out through the track hole, enhancing the pre-cooling effect of the air discharge pipe. At the same time, during the falling process of the extrusion plate, the elastic rope is stretched. During the stretching process of the elastic rope, it drives the sliding plate to move inside the pressing box. The sliding plate drives the cross plate to move, and the cross plate drives the scraping plate to move. During the movement of the scraping plate, it can scrape the daylily on the top of the perforated conveyor belt, further reducing the possibility of daylily accumulation and enhancing the pre-cooling treatment of the daylily on the side. The inside of the pressing box is provided with a condensation plate, which converts the internal air flow into cold air. When the two sliding plates approach each other, the sliding plates discharge the cold air inside the pressing box outwards through the round holes, thereby further enhancing the pre-cooling treatment of the daylily when the sponge board presses and dries the moisture of the daylily.

[0017] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The telescopic rod 63 drives the pressing box 64 to move up and down.

Start the motor 4. The motor 4 drives the rotating shaft 51 to rotate. The rotating shaft 51 drives the shaft sleeve 52 to rotate. The shaft sleeve 52 drives the perforated conveyor belt 53 to rotate. Start the telescopic rod 63. The telescopic rod 63 drives the tooth block sleeve 651 to move up and down. Subject to the blocking of the limiting rod 652, when the tooth block sleeve 651 moves up and down, it drives the irregular tooth sleeve plate 653 to rotate. When the irregular tooth sleeve plate 653 rotates, it drives the rotating bar 654 to rotate. Subject to the limitation of the round rod 655, the rotating bar 654 drives the round plate 674 to rotate. The round plate 674 drives the round sleeve housing 673 to rotate. The round sleeve housing 673 drives the rubber tooth plate 675 to rotate; Step 2: The telescopic rod 63 drives the pressing box 64 to move up and down. The pressing box 64 drives the sponge plate 6612 to descend. The tooth block sleeve 651 drives the square plate 661 to move up and down. The square plate 661 drives the connecting rod 662 to move up and down. Under the limitation of the track hole 664, the connecting rod 662 drives the pressing plate 667 to move up and down. When the pressing plate 667 descends, the air flow inside the condensation box 68 moves outwards through the air discharge pipe 668. At the same time, during the descent of the pressing plate 667, the elastic rope 6611 is stretched. During the stretching of the elastic rope 6611, it drives the sliding plate 6615 to move inside the pressing box 64. The sliding plate 6615 drives the cross plate 6617 to move. The cross plate 6617 drives the scraping plate 6618 to move; Step 3: During the rotation of the rubber tooth plate 675, it comes into contact with the daylily, causing the rubber tooth plate 675 to slide on the outer wall surface of the round sleeve 673. The rubber tooth plate 675 drives the arc plate 679 to move. The arc plate 679 drives the flexible rope 6711 to move. The flexible rope 6711 is stretched. The flexible rope 6711 drives the special-shaped scraping plate 6712 to rotate. At the same time, during the rotation of the round sleeve 673, it drives the suction fan 676 to rotate. The suction fan 676 generates negative pressure. The negative pressure absorbs the cold air inside the condensation box 68 into the inside of the round sleeve 673 through the elbow 672. The cold air enters the inside of the arc box 678 through the air pipe 677. The cold air enters the inside of the exhaust pipe 6714 through the arc box 678.
