Description

Technical Field

[0001] The invention relates to the technical field of cleaning equipment for a food steaming and extracting cage, and in particular to a special cleaning device for an extraction cage. Background Art

[0002] Cooking containers are often used in the food processing industry. Such containers are used for cooking materials and cooking liquids. In order to ensure that the cooked materials can be easily taken out of the cooking liquid, the materials are generally placed in an extraction cage in advance, and then the extraction cage and the materials are placed in the cooking container as a whole for cooking. Due to the cage structure of the extraction cage, the cooking liquid and the materials in the cage can still be in full contact. In addition, after the cooking is completed, all the materials in the cooking container can be taken out by directly taking the extraction cage out of the cooking liquid, which is very convenient.

[0003] However, in actual use, it is found that since the extraction liquid is cooked together with the material in the cooking liquid, when the extraction cage is taken out of the cooking liquid, not only a large amount of cooking liquid residue is attached to the cage surface, but also material residue. If the animal protein material is cooked, a large amount of grease will also adhere to the cage surface. 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 huge size of the extraction cage and the fact that it is composed of a large number of interlaced ribs, the extraction cage can only be cleaned manually by operators. This not only has low cleaning efficiency and high labor intensity, but also requires consumption of a large amount of cleaning fluid and water. Summary of the invention

[0055] A buffer block 38 is detachably fixedly disposed on one end of the lateral guide rod 37 of the cage body 31 that contacts the limiting slot plate 26 .

[0056] A guide protrusion 30 is provided at the top of the inner wall of the side wall of the tank body 1 at the side position where the swing frame 10 is located. 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.

[0058] The cage support frame 5 is fixedly connected to the inner wall of the arc-shaped liquid collecting hopper 3 through the diagonal support rod B25.

[0059] The process of using the special cleaning device for extraction cages is as follows: The top cover 2 is pulled up by the lifting ear 22, so that the top cover 2 is swung upward around the swing frame 10 to the maximum stroke, at which time the top opening of the tank body 1 is completely opened, and then the liquid inlet pipe C17 and the diagonal support rod A24 are separated from the top cover 2 respectively; then the cage body 31 of the extraction cage is inverted and lifted by the lifting device, and then the cover net 34 of the feeding port 32 located at the bottom of the lifted inverted cage body 31 is opened, at which time the cover net 34 swings downward under the action of its own weight, and then the lifting device lifts the cage body 31 with the open cover net 34 from top to bottom into the tank body 1; when lifting the cage body 31 into the tank body 1, first rotate the cage body 31 around the axis until the position of the lateral guide rod 37 and the guide groove 27 roughly corresponds, and then the bottom of the side of the cage body 31 facing the top cover 2 is connected with the guide protrusion 30, and using this as a fulcrum, adjust the cage body 31 to the corresponding position of the lateral guide rod 37 and the guide groove 27 and The cage 31 is in a vertical state as much as possible; then the cage 31 is slowly lowered by the sling, so that the lowermost lateral guide rod 37 of the cage 31 enters the range of the introduction ramp 29, and as the cage 31 is lowered, the lowermost lateral guide rod 37 of the cage 31 moves downward along the introduction ramp 29 into the guide groove 27. After the lowermost lateral guide rod 37 of the cage 31 enters the guide groove 27, the sling can increase the speed of the cage 31 and continue to lower it, so that the lateral guide rods 37 of the cage 31 enter the guide groove 27 one after another. After all the lateral guide rods 37 of the cage 31 enter the guide groove 27, the lowering speed of the cage 31 is reduced again by the sling, so that the cage 31 is slowly placed on the cage support frame 5, and at this time, the rotating liquid spray heads B7 extend into the cage 31 from the feeding port 32 respectively; then the sling is separated from the cage 31, and the liquid inlet pipe C is 17 is fixed to the liquid collecting chamber 16, the diagonal support rod 24 is fixed to the liquid inlet pipe C17 and the top cover 2 respectively, and then the top cover 2 is swung downward around the swing frame 10 through the lifting ear 22 until it is closed with the tank body 1. At this time, the rotating liquid spray head C8 extends downward from the gap between the vertical and horizontal bottom ribs 35 of the cage bottom frame 33 into the cage body 31, and the annular flange of the top cover 2 is located in the annular liquid collecting 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 liquid spray head A6, the atomizing spray head provided in the annular pipe 12, the rotating liquid spray head B7, the rotating liquid spray head C8 and the atomizing spray head provided in the liquid collecting chamber 16 all spray cleaning liquid to the cage body 31 in the pipe body 1.The atomizing nozzle can not only make the cage surface always full of tiny droplets to keep it moist, so that the cleaning liquid sprayed from the rotary spray head A6, rotary spray head B or rotary spray head C8 to a certain part of the cage 31 can quickly merge with the tiny droplets around the part of the cage 31, so that the cleaning liquid can quickly cover the surrounding parts of the cage, thereby ensuring the cleaning range and cleaning effect of the cleaning liquid, in addition, the atomizing nozzle makes the 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 body 1 sufficient, so that the rotary spray head A6, rotary spray head B or rotary spray head C8 can be sprayed to a certain part of the cage 31. The head C8 plays a certain blocking role because the cleaning liquid splashed when it is sprayed onto the cage body 31, and tries to avoid the cleaning liquid splashed when it is sprayed onto the cage body 31 from sticking to the inner wall of the side wall of the tank body 1 or the bottom of the top cover 2. After the cleaning liquid sticks to the inner wall of the side wall of the tank body 1 or the bottom of the top cover 2, the cleaning liquid does not participate in the cleaning of the cage body 31, and will directly drip along the inner wall of the side wall of the tank body 1, resulting in a reduction in the cleaning efficiency of the cleaning liquid; in addition, the cleaning liquid that finally remains on the inner wall of the side wall of the tank body 1 and the bottom of the top cover 2 also needs to be manually cleaned after the cage body 31 is cleaned and taken out of the tank body 1. The multiple rotating liquid spray heads A6 evenly distributed on the inner wall of the tank body 1 around the axis of the tank body 1 can clean the outer side, upper and lower sides or left and right sides of the axial ribs and annular ribs of the side wall of the cage body 31; the rotating liquid spray head B7 arranged at the bottom of the tank body 1 can clean the inner side, upper and lower sides or left and right sides of the axial ribs 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 respectively; the rotating liquid spray head C8 arranged at the top of the tank body 1 can clean the inner side, upper and lower sides or left and right sides of the axial ribs 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 bottom frame 33 respectively. During the cleaning process, when cleaning liquid inevitably splashes onto the inner wall of the side wall of the tank body 1, most of the cleaning liquid on the inner wall of the side wall of the tank body 1 will slide downward along the inner wall of the side wall of the tank body 1 due to gravity; when cleaning liquid inevitably splashes onto the bottom of the top cover 2, most of the cleaning liquid at the bottom of the top cover 2 will slide toward the edge along the top cover 2 to the annular flange due to gravity, and only needs to slide along the annular flange into the annular liquid collecting groove 18. The return pipe 19 provided at the bottom of the annular liquid collecting groove 18 will return the cleaning liquid in the annular liquid collecting groove 18 to the tank body 1, and continue to slide downward along the inner wall of the side wall of the tank body 1.By adjusting the discharge flow rate of the discharge pipe connected to the discharge port 4 or even temporarily closing the discharge pipe, the cleaning liquid used to clean the cage 31 and the cleaning liquid that slides down the inner wall of the side wall of the tank body 1 are accumulated in the arc-shaped liquid collecting hopper 3 and maintain a certain liquid level height, thereby achieving a certain immersion cleaning effect on the cover net 34. Moreover, after a certain height of cleaning liquid is accumulated in the liquid collecting hopper 3, the residue mixed in the cleaning liquid will settle. Then, when a certain liquid level is reached, the discharge pipe is fully opened, and there will be enough pressure to flush out the residue. If the discharge pipe is kept fully open, some residue will remain on the inner wall, which is not easy to be directly flushed away by the cleaning liquid and also needs to be cleaned afterwards. When the cage 31 is cleaned, the cleaning liquid supply device is closed, and after the cleaning liquid accumulated in the liquid collecting bucket 3 is completely discharged, the top cover 2 is opened, and the liquid inlet pipe C17 and the diagonal support rod A24 are disassembled and separated from the top cover 2 again, and the cage 31 is lifted out of the tank body 1. Finally, the operator cleans the inside of the tank body 1 and the bottom of the top cover 2 respectively, so as to prepare for the cleaning of the next cage 31. The cleaning liquid discharged from the liquid discharge port can be circulated to the cleaning liquid supply device for cleaning again after filtering. According to the cleaning system of the enterprise's cleaning and extraction cage or the instruction manual of the cleaning liquid, the cleaning liquid will be replaced when it cannot be used for cleaning.
