Description

Technical Field

[0001] This invention relates to the technical field of a cleaning device for a food steaming and extraction cage, specifically to a dedicated cleaning device for the extraction cage. Background Technology

[0002] Cooking containers are frequently used in the food processing industry. These containers are used for cooking materials and cooking liquids. To ensure that the cooked materials can be easily removed from the cooking liquid, the materials are usually placed in an extraction cage beforehand. Then, the extraction cage and the materials are placed together in the cooking container for cooking. Due to the cage structure, the cooking liquid and the materials inside the cage can still maintain full contact. In addition, after cooking, all materials in the cooking container can be removed simply by removing the extraction cage from the cooking liquid, which is very convenient.

[0003] However, in actual use, it was found that because the extractant is cooked together with the material in the cooking liquid, when the extraction cage is removed from the cooking liquid, the surface of the cage is not only covered with a large amount of cooking liquid residue, but also with material residue. If the material is animal protein, a large amount of grease will also adhere to the surface of the cage. All of these will affect the next use of the extraction cage, and the cooking cage needs to be cleaned after each use.

[0004] However, due to the enormous size of the extraction cage and its numerous intersecting ribs, cleaning it can currently only be done manually by operators. This process is not only inefficient and labor-intensive, but also consumes a large amount of cleaning solution and water. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a special cleaning device for extraction cages. Through the cleaning tank and the corresponding rotating spray head and atomizing spray head on the top cover, the inner and outer sides, top and bottom of the cage placed upside down in the tank can be effectively cleaned. The cage cover net can also be immersed in the arc-shaped liquid collection hopper at the bottom of the tank for effective cleaning.

[0006] The technical solution adopted in this invention is:

[0007] A special cleaning device for extraction cages includes a tank. The top of the tank is connected to a top cover that is oscillatingly connected to the top of the tank via a swing frame.

When the top cover is closed and fixed with the tank body, the bottom edge of the annular flange is located inside the annular liquid-gathering groove, and the bottom of the annular liquid-gathering groove is connected to the tank body through a return pipe equipped with a valve.

[0015] A further improvement of the present invention is that the inner sidewall of the tank is provided with axially arranged limiting groove plates on two opposite sides, the groove opening of the limiting groove plate faces the axis of the tank, and the groove opening of the limiting groove plate forms a guide groove that matches the lateral guide rod provided on the sidewall of the cage.

The cage body 31 is provided with a cover net 34 corresponding to the feeding port 32, which is swaying and connected to the middle of the cage body 31. Under its own weight, the cover net 34 swings downward to the maximum stroke. The cover net 34 is symmetrically arranged on two opposite sides of the cage body 1, and the opposite side of the cover net 34 is swaying and connected to the cage body 31. The back side of the cover net 34 is provided with a latch connected to the cage body 31.

[0039] The rotating spray head C8 is connected to the inlet pipe B15 fixed to the top of the top cover 2. The bottom of the top cover 2 is fixed with a vertically arranged inlet pipe C17. The top end of the inlet pipe C17 is fixed to the top cover 2 and connected to the inlet pipe B15. The bottom end of the inlet pipe C17 is connected to the rotating spray head C8.

[0040] The liquid inlet pipe C17 is detachably and fixedly connected to the top cover 2.

[0041] Two rotating spray heads 8 are provided, which are symmetrically arranged on two opposite sides of the axis of the tank body 1, and extend downward into the cage body 31 from the gap between the longitudinal and transverse bottom ribs 35 of the cage body base 33 located above the cage body support frame 5.

[0042] One of the rotating nozzles C8 is located above the topmost rotating nozzle A6, and the other rotating nozzle C8 is located between the two topmost rotating nozzles A6.

[0043] The rotating nozzle C8 located above the topmost rotating nozzle A6 corresponds to the position of the cage base 33 of the cage 31 placed on the cage support frame 5.

[0044] The bottom center of the top cover 2 is coaxially provided with a liquid collection chamber 16. The connection between the liquid inlet pipe B15 and the top cover 2 is located within the liquid collection chamber 16.

[0051] The outer edge of the top opening of the tank 1 is provided with an annular liquid collection groove 18 coaxially. The top edge of the groove wall of the annular liquid collection groove 18 is flush with the top edge of the tank 1. The top cover 2 is an arc-shaped structure that slopes downward from the middle to the edge, and the edge of the top cover 2 is bent downward to form an annular flange. When the top cover 2 is closed and fixed to the tank 1, the bottom edge of the annular flange is located inside the annular liquid collection groove 18.

[0052] The lowest point of the arc panel is higher than the height of the connection between the edge of the top cover 2 and the annular flange bend.

[0053] The inner sidewall of the tank 1 is symmetrically provided with axially arranged limiting groove plates 26 on two opposite sides. The groove opening of the limiting groove plate 26 faces the axis of the tank 1, and the groove opening of the limiting groove plate 26 forms a guide groove 27 that matches the lateral guide rod 37 provided on the sidewall of the cage 31.

[0054] Multiple connecting plates 28 are sequentially provided on both sides of the limiting groove plate 26 along the extension direction of the limiting groove plate 26 and are fixedly connected to the inner wall of the tank body 1.

[0055] The top of the limiting groove plate 26 extends upward to the top edge of the tank body 1, and the bottom of the limiting groove plate 26 extends downward to the position of the tank body 1 corresponding to the top surface of the cage support frame 5.

[0056] The two sides of the top of the limiting groove plate 26 are connected to the top edge of the tank body 1 through the guide slope plate 29.

[0057] A buffer block 38 is detachably fixed at one end of the side guide rod 37 of the cage 31 that contacts the limiting groove plate 26.

[0058] A guide protrusion 30 is provided on the top of the inner wall of the tank 1 located on the side of the swing frame 10. The top of the guide protrusion 30 is inclined downward along the direction facing the axis, and the bottom edge of the guide protrusion 30 is inclined upward along the direction facing the axis.

[0059] The guide protrusion 30 is located above the axial tube 11, and when the cage body 31 is placed upside down on the cage support frame 5, the bottom of the guide protrusion 30 is below the bottom of the cage body 31, and the top of the guide protrusion 30 is above the bottom of the cage body 31.

[0060] The cage support frame 5 is fixedly connected to the inner wall of the arc-shaped liquid collection hopper 3 by the diagonal brace B25.

[0061] The process of using the special cleaning device for extraction cages is as follows:

[0062] The top cover 2 is lifted by the lifting lug 22, causing it to swing upwards around the swing frame 10 to its maximum stroke. At this point, the top opening of the tank 1 is fully open. Then, the inlet pipe C17 and the diagonal brace A24 are separated from the top cover 2. The cage body 31 of the extraction cage is then lifted up by the lifting device after being inverted. The cover 34 of the feeding port 32 at the bottom of the inverted cage body 31 is then opened. The cover 34 swings downwards under its own weight. The lifting device then lowers the cage body 31 with the cover 34 open into the tank 1 from top to bottom. When lowering the cage body 31 into the tank 1, the cage body 31 is first rotated around the axis until the position of the side guide rod 37 roughly corresponds to the position of the guide groove 27. Then, the bottom of the side of the cage body 31 facing the top cover 2 is connected to the guide protrusion 30. Using this as a fulcrum, the cage body 31 is adjusted to the corresponding position of the side guide rod 37 and the guide groove 27. The cage 31 is positioned as vertically as possible. Then, the cage 31 is slowly lowered using a lifting device, allowing the bottommost side guide rod 37 of the cage 31 to enter the area of ​​the guide slope 29. As the cage 31 is lowered, the bottommost side guide rod 37 moves down the guide slope 29 into the guide groove 27. Once the bottommost side guide rod 37 is in the guide groove 27, the lifting device can increase the speed of lowering the cage 31, allowing the side guide rods 37 to enter the guide groove 27 sequentially. After all the side guide rods 37 are in the guide groove 27, the lowering speed of the cage 31 is reduced again using the lifting device, allowing the cage 31 to be slowly placed on the cage support frame 5. At this point, the rotating spray head B7 extends into the cage 31 from the feeding port 32. Then, the lifting device is separated from the cage 31, and the liquid inlet pipe C... 17 is fixed to the liquid collection chamber 16, and the diagonal brace 24 is fixed to the liquid inlet pipe C17 and the top cover 2 respectively. Then, the top cover 2 is swung downward around the swing frame 10 through the lifting lug 22 until it is closed with the tank body 1. At this time, the rotating spray head C8 extends downward into the cage body 31 from the gap between the longitudinal and transverse bottom ribs 35 of the cage body base frame 33, and the annular flange of the top cover 2 is located in the annular liquid collection groove 18 of the tank body 1. Then, the cleaning liquid supply device connected to the liquid inlet 13, the liquid inlet pipe A14 and the liquid inlet pipe B15 is started, so that the rotating spray head A6, the atomizing nozzle of the annular pipe 12, the rotating spray head B7, the rotating spray head C8 and the atomizing nozzle of the liquid collection chamber 16 all spray cleaning liquid into the cage body 31 inside the pipe body 1.The atomizing nozzles ensure that the surface of the cage is constantly moistened with tiny droplets. This allows the cleaning fluid sprayed from rotating nozzles A6, B, or C8 onto a specific area of ​​the cage 31 to quickly coalesce with the surrounding droplets, ensuring rapid coverage and effective cleaning. Furthermore, the atomizing nozzles generate sufficient water mist between the top of the cage 31 and the top cover 2, and between the side wall of the cage 31 and the side wall of the tank 1, thus effectively controlling the water droplets sprayed from rotating nozzles A6, B, or C8. The cleaning fluid splashed by the head C8 when spraying onto the cage 31 serves to a certain extent to block it, minimizing the amount of cleaning fluid splashed onto the inner wall of the tank 1 or the bottom of the top cover 2. If the cleaning fluid gets onto the inner wall of the tank 1 or the bottom of the top cover 2, it will not participate in cleaning the cage 31 and will drip directly down the inner wall of the tank 1, resulting in a reduction in the cleaning filtration efficiency of the cleaning fluid. In addition, the remaining residue on the inner wall of the tank 1 and the bottom of the top cover 2 will require additional manual cleaning of the inner wall of the tank 1 and the bottom of the top cover 2 after cleaning the cage 31 and removing the cage 31 from the tank 1. The multiple rotating spray heads A6, evenly distributed around the axis of the tank body 1 on the inner wall of the tank body 1, can clean the outer, upper and lower, or left and right sides of the axial and annular ribs of the side wall of the cage body 31; the rotating spray head B7 at the bottom of the tank body 1 can clean the inner, upper and lower, or left and right sides of the axial and annular ribs of the lower side wall of the cage body 31, as well as the part at the feeding port 32 of the cage body 31 and the cover net 34; the rotating spray head C8 at the top of the tank body 1 can clean the inner, upper and lower, or left and right sides of the axial and annular ribs of the upper side wall of the cage body 31, as well as the longitudinal and transverse bottom ribs 35 of the cage body base frame 33. During the cleaning process, when cleaning fluid inevitably splashes onto the inner wall of the side wall of the tank 1, most of the cleaning fluid on the inner wall of the side wall of the tank 1 will slide down along the inner wall of the side wall of the tank 1 due to gravity. When cleaning fluid inevitably splashes onto the bottom of the top cover 2, most of the cleaning fluid at the bottom of the top cover 2 will slide down along the edge of the top cover 2 to the annular flange due to gravity, and then slide down along the annular flange into the annular liquid collection tank 18. The return pipe 19 provided at the bottom of the annular liquid collection tank 18 will return the cleaning fluid in the annular liquid collection tank 18 to the tank 1, and continue to slide down along the inner wall of the side wall of the tank 1.By adjusting the flow rate of the drain pipe connected to the drain port 4, or even temporarily closing the drain pipe, the cleaning fluid of the cleaning cage 31 and the cleaning fluid sliding down the inner wall of the tank 1 can accumulate in the arc-shaped liquid collection hopper 3 and maintain a certain liquid level. This can achieve a certain soaking and cleaning effect on the cover mesh 34. Moreover, after the cleaning fluid accumulates to a certain height in the liquid collection hopper 3, the residue mixed in the cleaning fluid will settle. Then, after reaching a certain liquid level, the drain pipe can be fully opened, and there will be enough pressure to flush out the residue. If the drain pipe is kept fully open, some residue will remain on the inner wall and will not be easily flushed away by the cleaning fluid. It will also need to be cleaned afterwards. After cage 31 is cleaned, the cleaning fluid supply device is turned off. Once the cleaning fluid accumulated in the collection hopper 3 is completely drained, the top cover 2 is opened, and the inlet pipe C17 and the diagonal support rod A24 are disassembled from the top cover 2. Cage 31 is then lifted out of tank 1. Finally, the operator cleans the inside of tank 1 and the bottom of the top cover 2 to prepare for cleaning the next cage 31. The cleaning fluid discharged from the drain port can be filtered and recycled back to the cleaning fluid supply device for further cleaning. According to the company's cleaning procedure for the extraction cages or the cleaning fluid's instruction manual, the cleaning fluid should be replaced when it reaches a point where it can no longer be used for cleaning.
