Technical Field
[0001] This utility model belongs to the technical field of pre-cleaning devices, specifically relating to a pre-cleaning device for quick-frozen foods. Background Technology
[0002] In recent years, frozen foods, which are foods that have undergone rapid freezing and are typically stored at -18 degrees Celsius or lower, have become increasingly popular. This has greatly enriched people's dietary choices, especially in today's fast-paced lifestyle, where frozen foods are favored by consumers for their convenience, speed, and nutritional value. Frozen foods come in a wide variety, including frozen vegetables, fruits, meats, seafood, pastries, and cooked foods, covering almost every aspect of daily diet.
[0003] Currently, the production process of frozen foods mainly includes raw material selection, pretreatment, quick-freezing, packaging, and storage. Among these, pretreatment is a very important step, which includes cleaning, cutting, and seasoning.
[0004] The cleaning process is a crucial part of the hygiene of frozen foods, directly affecting their hygienic quality. The cleaning steps mainly involve removing dirt, mud, and other impurities from the surface of raw materials such as vegetables, fruits, and meats. However, most cleaning methods rely on manual hand washing or rinsing with running water, which cannot completely remove dirt from deep crevices. Therefore, further improvements are needed to enhance the cleanliness of raw materials for frozen foods. Utility Model Content
[0005] The purpose of this invention is to provide a pre-cleaning device for quick-frozen foods, which aims to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A pre-cleaning device for quick-frozen foods, comprising,
[0008] The cleaning mechanism includes a base, a cleaning tank, a bottom ultrasonic generator, a side wall ultrasonic generator, and a storage bin. The cleaning tank is mounted on the top of the base via support legs. The bottom ultrasonic generator is mounted on the lower end of the cleaning tank. The side wall ultrasonic generators are mounted on both sides of the outside of the cleaning tank. The inside of the cleaning tank contains a storage bin for storing the materials to be cleaned. The storage bin has a perforated grid structure.
[0009] The lifting mechanism includes a support frame, a motor, a support shaft, a bearing, a winding roller, and a wire rope. The support frame has a U-shaped structure, and its lower two sides are fixed to the surface of a base. The upper two sides of the support frame are symmetrically fixed with brackets. The motor has a drive shaft inside, and the end of the drive shaft is fixedly connected to the support shaft via a coupling. The end of the support shaft away from the motor is rotatably mounted inside the bearing. The lower end of the outer ring wall of the bearing is fixedly assembled to the surface of the support frame via a bracket. A winding roller is fixedly sleeved on the surface of the support shaft, and a wire rope is wound on the surface of the winding roller. One end of the wire rope is fixedly mounted on the outer wall of the winding roller.
[0010] As a preferred embodiment of this utility model, a waste discharge port is fixedly installed through one side of the lower end of the cleaning tank, and a valve is provided on the waste discharge port, with the valve core embedded inside the waste discharge port.
[0011] In a preferred embodiment of this utility model, both sides of the support frame are fixed with an inner sleeve, the surface of the wire rope is slidably sleeved with the inside of the inner sleeve, and a rope loop is assembled at the lower end of the wire rope.
[0012] In a preferred embodiment of this utility model, the lower ends of the rope rings distributed on both sides are fixedly installed with the same lifting frame by a bracket. Limiting rods are respectively installed on both sides of the lifting frame, and limiting grooves are opened on both sides of the inner wall of the support frame. The surface of the limiting rod is slidably and tightly attached to the inner wall surface of the limiting groove.
[0013] In a preferred embodiment of this utility model, hooks for suspension connection are fixedly installed on both sides of the upper end of the storage box, and a hanging ring is assembled on the inner side of the lifting frame through a bracket, with the end of the hook inserted into the inside of the hanging ring.
[0014] As a preferred embodiment of this utility model, the lifting frame is further provided with an agitation component, the agitation component includes a bearing, the bearings are fixedly installed through both sides of the lifting frame, a shaft is installed through the inside of the bearing, the surface of the shaft is interference-fitted with the inner ring wall of the bearing, and several blades are fixedly distributed on the lower end of the shaft and on the surface inside the storage box.
[0015] In a preferred embodiment of this utility model, a second motor is provided at the upper end of the shaft. The outer ring wall of the second motor is fixed to the surface of the lifting frame by a bracket. A second rotating shaft for driving is provided inside the second motor. The end of the second rotating shaft is fixedly connected to the end of the shaft by a coupling.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This solution significantly improves the cleaning effect by using bottom and side wall ultrasonic generators to work alternately. The ultrasonic cavitation effect can penetrate deep into the gaps on the material surface and effectively remove dirt and residues. Since the two ultrasonic generators do not work at the same time, the cleaning quality is not reduced due to mutual interference.
[0018] 2. As described in 1, the motor, together with the winding roller and the wire rope, achieves precise control of the storage box. The sliding cooperation between the limit rod and the limit groove effectively reduces shaking and ensures the stability of the lifting process. The connection method between the hook and the hanging ring not only ensures the firmness of the suspension, but also facilitates the quick disassembly and installation of the storage box.
[0019] 3. As described in 2, the intermittent agitation of the blades in the storage bin causes the position of the raw materials to change continuously, avoiding the problem of incomplete cleaning in certain areas. The motor drives the shaft and blades to rotate, ensuring that the agitation force is moderate. This will not affect the ultrasonic effect due to excessive agitation, and will effectively improve the cleaning coverage. Attached Figure Description

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0032] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0033] Example 1
[0034] Reference Figures 1-6 This is the first embodiment of the present invention, which provides a pre-cleaning device for quick-frozen food, comprising:
[0035] The cleaning mechanism 1 includes a base 10, a cleaning tank 11, a bottom ultrasonic generator 12, a side-wall ultrasonic generator 13, and a storage tank 14. The cleaning tank 11 is mounted on the top of the base 10 via support legs. The bottom ultrasonic generator 12 is mounted on the lower end of the cleaning tank 11. The side-wall ultrasonic generators 13 are mounted on both sides of the outside of the cleaning tank 11. The storage tank 14, which is a perforated grid structure, is placed inside the cleaning tank 11 to store the materials to be cleaned. The storage tank 14 contains clean water. The bottom ultrasonic generator 12 and the side-wall ultrasonic generator 13 work alternately in a single cycle, making the cleaning of raw materials for frozen food more thorough and clean. The ultrasonic generators in the two positions do not work at the same time to avoid affecting the cleaning quality due to synchronous operation. The ultrasonic generators convert electrical energy into mechanical energy through the inverse piezoelectric effect. Both ultrasonic generators are connected to frequency adjustment switches and power adjustment switches via wires, which can adjust the frequency or power of the ultrasonic generators. The storage tank 14 has a perforated structure, which facilitates the normal operation of cavitation effect during the cleaning process.
[0036] The lifting mechanism 2 includes a support frame 20, a motor 21, a support shaft 22, a shaft seat 23, a winding roller 24, and a wire rope 25. The support frame 20 has a U-shaped structure, and its lower ends are fixed to the surface of the base 10 on both sides. The upper ends of the support frame 20 are symmetrically fixed to the motor 21 via brackets. The motor 21 has a drive shaft inside, and the end of the drive shaft is fixedly connected to the support shaft 22 via a coupling. The end of the support shaft 22 away from the motor 21 is rotatably mounted inside the shaft seat 23. The lower end of the outer ring wall of the shaft seat 23 is connected to the support frame 25 via a bracket. The surface of the support shaft 22 is fixedly assembled with a winding roller 24. A steel wire rope 25 is wound around the surface of the winding roller 24. One end of the steel wire rope 25 is fixedly installed on the outer wall of the winding roller 24. The motor 21 is a brake type, which can lock the shaft 24 in place after power failure. The motor 21 is connected to a forward and reverse switch via a wire. The forward and reverse switch is model HY2-8, which can adjust the forward and reverse rotation of the motor 21. Thus, the shaft 21 can drive the support shaft 22 to rotate in both directions, and the winding roller 24 can perform the winding and unwinding operations of the steel wire rope 25.
[0037] The cleaning tank 11 has a waste discharge port 15 fixed through one side of the lower end. A valve 16 is installed on the waste discharge port 15. The valve core of the valve 16 is embedded inside the waste discharge port 15. The valve 16 can shut off or open the waste discharge port 15. The waste discharge port 15 can discharge the water in the cleaning tank 11 after a single cleaning.
[0038] The support frame 20 has an inner sleeve 26 fixed through both sides. The surface of the wire rope 25 is slidably connected to the inside of the inner sleeve 26. The lower end of the wire rope 25 is equipped with a rope loop 27. The inner sleeve 26 serves as a transition support. The inner sleeve 26 is made of rubber material, which can reduce friction damage with the support frame 20 when the wire rope 25 passes through. The rope loop 27 is installed at the end of the wire rope 25 and can be used for transition connection with the lifting frame 28 to ensure the stable connection between the wire rope 25 and the lifting frame 28. When the wire rope 25 is wound or released, the height of the lifting frame 28 can be easily adjusted, so that the storage box 14 can be lowered or removed relative to the cleaning box 11.
[0039] The lower ends of the rope loops 27 distributed along both sides are fixedly installed with the same lifting frame 28 by brackets. Limiting rods 29 are respectively installed on both sides of the lifting frame 28. Limiting grooves 210 are opened on both sides of the inner wall of the support frame 20. The surface of the limiting rod 29 slides and fits tightly against the inner wall of the limiting groove 210. When the lifting frame 28 moves up and down, the storage box 14 suspended on the lifting frame 28 will move synchronously. By sliding the limiting rod 29 on the inner side of the limiting groove 210, the up and down movement of the lifting frame 28 can be stabilized, thereby avoiding the large swaying effect caused by the lifting or releasing of the wire rope 25.
[0040] The upper sides of the storage box 14 are respectively fixedly equipped with hooks 2001 for suspension connection. The inner side of the lifting frame 28 is equipped with a hanging ring 2002 through a bracket. The end of the hook 2001 is inserted into the hanging ring 2002. The hanging ring 2002 and the hook 2001 cooperate to facilitate the stable suspension of the storage box 14 based on the lifting frame 28. At the same time, when disassembling, the storage box 14 is lifted up so that it can move upward relative to the lifting frame 28, so that the hook 2001 and the hanging ring 2002 slide off, and the storage box 14 can be separated from the lifting frame 28.
[0041] The lifting frame 28 is also equipped with an agitation component 3, which includes a bearing 30. The bearing 30 is fixed through both sides of the lifting frame 28. A shaft 31 is installed through the inside of the bearing 30. The surface of the shaft 31 is interference-fitted with the inner ring wall of the bearing 30. Several blades 32 are fixedly distributed on the lower end of the shaft 31 and the surface inside the storage box 14. The shaft 31 can rotate based on the bearing 30. The shaft 31 can synchronously drive the blades 32 to rotate, so that it can agitate the material that has been submerged in water in the cleaning tank 11 and is located inside the storage box 14. This achieves positional changes of the material in different areas, thereby enabling more efficient cleaning under the ultrasonic cavitation effect. The agitation component 3 operates intermittently to avoid continuous agitation that could generate eddies in the water and affect the ultrasonic cleaning process.
[0042] The upper end of the shaft 31 is equipped with a second motor 33. The outer ring wall of the second motor 33 is fixed to the surface of the lifting frame 28 by a bracket. The inside of the second motor 33 is equipped with a second rotating shaft for driving. The end of the second rotating shaft is fixedly connected to the end of the shaft 31 by a coupling. After the second motor 33 is powered on, it can drive the second rotating shaft, which synchronously causes the shaft 31 to rotate, which allows the blades 32 to rotate, agitate the material, switch positions, and improve the comprehensiveness of cleaning.
[0043] In practice
[0044] The cleaning mechanism 1 of this solution achieves efficient cleaning through the alternating operation of the bottom ultrasonic generator 12 and the side wall ultrasonic generator 13. The bottom ultrasonic generator 12 is installed at the lower end of the cleaning tank 11, and the side wall ultrasonic generator 13 is distributed on both sides of the cleaning tank 11. Both are connected to frequency and power adjustment switches via wires, and their parameters can be adjusted independently to meet the cleaning needs of different ingredients. During operation, the bottom ultrasonic generator 12 starts first, using the inverse piezoelectric effect to convert electrical energy into high-frequency mechanical vibration, generating a cavitation effect in the water. This effect acts on the surface of the ingredients through the hollow grid structure of the storage tank 14, removing the attached substances. Subsequently, the side wall ultrasonic generator 13 starts, supplementing the cavitation effect from the horizontal direction and covering the cleaning blind spots. The alternating operation of the two avoids the energy attenuation caused by sound wave interference when working synchronously, ensuring the uniformity of cleaning. After cleaning is completed, the valve 16 of the waste discharge port 15 is opened to discharge the wastewater for the next use.
[0045] The lifting mechanism 2 drives the support shaft 22 to rotate forward and backward via motor 21, which in turn drives the winding roller 24 to wind and unwind the wire rope 25, thereby lifting and lowering the storage box 14. Motor 21 is a brake type, and after power failure, the shaft is locked in place to ensure safety. The wire rope 25 passes through the inner sleeve 26 of the support frame 20, and the lower end is connected to the rope ring 27 and the lifting frame 28. The limit rods 29 on both sides slide along the limit groove 210 to prevent shaking. The cooperation between the hook 2001 and the hanging ring 2002 allows the storage box 14 to be quickly disassembled. During operation, motor 21 is controlled by a forward and reverse switch. When the winding roller 24 winds the wire rope 25, the lifting frame 28 moves the storage box 14 upward and away from the cleaning box 11; when unwinding, it sinks into the water. The tight sliding design of the limit groove 210 and the limit rod 29 ensures the stability of the lifting frame 28 and the storage box 14 during the lifting process.
[0046] The stirring component 3 drives the shaft 31 to rotate via motor 2 33, which in turn drives the blades 32 to intermittently stir the ingredients in the storage box 14. The shaft 31 and the bearing 30 are interference-fitted to ensure rotational accuracy. The blades 32 are distributed to enhance the stirring range. During operation, motor 2 33 starts intermittently, and the rotating shaft 2 drives the shaft 31 to rotate via the coupling, so that the ingredients continuously change position during ultrasonic cleaning, avoiding dead corners caused by accumulation. Intermittent operation can prevent continuous stirring from forming vortex interference cavitation effect.
