Description

Technical Field

[0001] This utility model relates to the field of thawing device technology, and more specifically to a rapid thawing device for food testing based on reciprocating motion. Background Technology

[0002] Food safety refers to food that is non-toxic, harmless, meets the necessary nutritional requirements, and does not cause any acute, subacute, or chronic harm to human health. Therefore, food testing is crucial. However, frozen foods need to be thawed before testing. In existing thawing devices, as ice crystals melt during thawing, hydrophilic colloids inside the cells absorb water, resulting in water gradually diffusing and permeating into the cells.

[0003] For example, a rapid thawing device for food testing, with prior art announcement number CN222994124U, allows thawing of food by placing it on top of a mesh panel and using a hot air blower. The collection tray prevents the melted liquid from dripping onto the food below and causing damage.

[0004] However, the above-mentioned existing technology still has the following problems when used: using a rotating defrosting cage in conjunction with a water spray hole to defrost food by rotating it results in low defrosting efficiency due to the limited range of water sprayed. Furthermore, during rotation, some food debris will detach and scatter inside the defrosting device, making it difficult to clean later. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a rapid thawing device for food testing based on reciprocating motion. An electric multi-stage telescopic rod drives the material box to reciprocate up and down, and a filter, solenoid valve, and circulating pump ensure continuous circulation of thawing water. The flowing thawing water constantly exchanges heat with the food, resulting in rapid thawing, significantly shortening thawing time and improving subsequent testing efficiency. A water guide hopper collects thawing water dripping from the material box, preventing overflow and pollution, and avoiding water waste, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid thawing device for food testing based on reciprocating motion, comprising a thawing chamber, water guide buckets fixedly provided on both sides of the top of the thawing chamber, a top plate fixedly provided on the top of the two water guide buckets, a linear module fixedly provided on the top of the top plate, an electric multi-stage telescopic rod fixedly provided at the rear end of the linear module, a rectangular through hole opened at the bottom of the top plate, the bottom of the electric multi-stage telescopic rod passing through the rectangular through hole and extending into the thawing chamber, a material box provided inside the thawing chamber, a lid provided on the top of the material box, the top of the lid connected to the bottom end of the electric multi-stage telescopic rod, and multiple equally spaced openings opened on both the material box and the lid.

[0007] In a preferred embodiment, the lid and the material box are connected by a plurality of evenly distributed buckles. Using buckles to connect the lid and the material box can not only improve the connection between the two, but also make it easier to separate the two, making them more convenient to use.

[0008] In a preferred embodiment, baffles are hinged to both the front and rear sides of the thawing box. The baffles are located between the two water guide buckets and act as a barrier between the two water guide buckets to prevent thawing water from flowing to the outside.

[0009] In a preferred embodiment, mounting plates are fixedly provided on both sides of the outer wall of the two baffles, and rotating rods are fixedly provided on the mounting plates. Pins are sleeved on the rotating rods, and slots that are compatible with the pins are fixedly provided on both the front and rear sides of the two water guide buckets. The pins are inserted into the slots, and the baffles and water guide buckets are connected by pins, which makes it very quick to use.

[0010] In a preferred embodiment, handles are fixedly provided on the opposite sides of the two baffles. The handles are located between two pins, and the design of the handles makes it easy for workers to quickly flip the baffles.

[0011] In a preferred embodiment, a filter screen is fixedly installed inside the thawing chamber, and a solenoid valve is fixedly installed through the bottom of the thawing chamber. The solenoid valve is connected to a circulation pump, and the inlet of the circulation pump is connected to the inside of the thawing chamber through a hose.

[0012] In a preferred embodiment, a base is fixedly provided at the bottom of the thawing box, and the top of the base is fixed to the bottom of the two water guide buckets by a support plate to improve the stability of the thawing box and the water guide buckets.

[0013] The technical effects and advantages of this utility model are as follows: This invention uses a lid and a container to enclose food in thawing water for thawing. An electric multi-stage telescopic rod drives the container to move up and down. A filter, solenoid valve, and circulation pump keep the thawing water circulating. The flowing thawing water constantly exchanges heat with the food. Compared with the static water method, the thawing speed is faster, which significantly shortens the thawing time and improves the efficiency of subsequent testing. In addition, the material box is automatically moved into the water guide hopper by an electric multi-stage telescopic rod and linear module. The water guide hopper allows the dripping thawing water to flow back into the thawing tank, which can prevent overflow from causing pollution and waste of water resources.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Refer to the instruction manual appendix Figures 1-5 This utility model provides a rapid thawing device for food testing based on reciprocating motion, including a thawing box 1. Water guide buckets 2 are fixedly provided on both sides of the top of the thawing box 1. A top plate 3 is fixedly provided on the top of the two water guide buckets 2. A linear module 4 is fixedly provided on the top of the top plate 3. An electric multi-stage telescopic rod 5 is fixedly provided at the rear end of the linear module 4. A rectangular through hole 6 is opened at the bottom of the top plate 3. The bottom of the electric multi-stage telescopic rod 5 passes through the rectangular through hole 6 and extends into the thawing box 1. A material box 7 is provided inside the thawing box 1. A box cover 8 is provided on the top of the material box 7. The top of the box cover 8 is connected to the bottom end of the electric multi-stage telescopic rod 5. Multiple equally spaced openings 9 are opened on both the material box 7 and the box cover 8.

[0018] Linear module 4 is a device used in the field of automated industry to realize linear motion. By selecting appropriate transmission and drive methods, linear module 4 converts rotary motion into linear motion, or precisely controls and positions objects on a straight line. Electric multi-stage telescopic rod 5 is a device that integrates multi-stage telescopic mechanism and electric actuator. It is usually composed of multiple nested piston rods. The ball screw is driven to rotate by a servo motor, which drives the screw pair installed on the piston of the telescopic rod to perform reciprocating linear motion, thereby realizing multi-stage telescopic movement.

[0019] like Figure 3As shown, the lid 8 and the material box 7 are connected by multiple evenly distributed buckles 10. The buckle 10 mainly consists of a fixed end, a movable end, and a locking mechanism. When connecting the lid 8 and the material box 7, manually pushing the movable end, such as pressing down the buckle lever, will cause the "protrusion / hook" of the movable end to contact the "groove / hole" of the fixed end. Through the inclined guide structure, the movable end can easily be inserted into the fixed end. At the same time, the spring built into the movable end is compressed, generating a continuous "rebound force" that presses the movable end tightly onto the fixed end, preventing natural loosening due to vibration or tilting. This ensures a firm and sealed connection between the lid 8 and the material box 7.

[0020] In addition, such as Figure 2 and Figure 5 As shown, a water supply pipe for supplying water to the inside of the defrosting chamber 1 is passed through the top of the top plate 3. The design of the water supply pipe makes it easy to replenish defrosting water within the standard temperature range.

[0021] The defrosting chamber 1 is equipped with a filter screen 17 inside. A solenoid valve 18 is fixedly installed through the bottom of the defrosting chamber 1. The solenoid valve 18 is a valve body whose liquid flow path is controlled by electromagnetic force. When the solenoid valve 18 is energized, the electromagnetic coil generates electromagnetic attraction to lift the valve core, opening the valve. When the power is off, the electromagnetic force disappears, and the valve core is pressed against the valve seat by spring force, closing the valve. The solenoid valve 18 is connected to a circulation pump 19. The circulation pump 19 is a mechanical device used to circulate fluids (such as liquids, gases, or gas-liquid mixtures) in a closed loop or specific system. The inlet of the circulation pump 19 is connected to the upper part of the defrosting chamber 1 via a flexible hose (e.g., ...). Figure 2 As shown in the figure, a base 20 is fixedly provided at the bottom of the thawing box 1, and the top of the base 20 is fixed to the bottom of the two water guide hoppers 2 by a support plate 21.

[0022] In practice, the staff first put the food to be thawed and tested into a sealed packaging bag, then put it into the material box 7, and use multiple box buckles 10 to secure the box lid 8 to the material box 7. Then, the electric multi-stage telescopic rod 5 drives the material box 7 to be immersed in the thawing water in the thawing chamber 1, while driving the material box 7 to move up and down. The water in the thawing chamber 1 is filtered by the filter screen 17 and then flows back into the thawing chamber 1 through the solenoid valve 18 and the circulation pump 19, forming a continuous water flow. The flowing thawing water constantly exchanges heat with the food. Compared with the static water method, the thawing speed is faster, thus significantly shortening the thawing time and improving the efficiency of subsequent testing. After thawing, the electric multi-stage telescopic rod 5 drives the material box 7 to rise above the water surface. The linear module 4 then drives the electric multi-stage telescopic rod 5 to move to the left or right, transporting the material box 7 to the water guide hopper 2 on the left or right side of the thawing box 1. The dripping thawing water is collected by the water guide hopper 2 and flows back into the thawing box 1 to avoid overflow, pollution, and waste of water resources.

[0023] Refer to the instruction manual appendix Figure 1 and Figure 4 The defrosting box 1 is hinged with baffles 11 on both the front and rear sides. The baffles 11 are located between the two water guides 2. Mounting plates 12 are fixed on both sides of the outer wall of the two baffles 11. A rotating rod 13 is fixed on the mounting plate 12. A pin 14 is sleeved on the rotating rod 13. Slots 15 that are adapted to the pins 14 are fixed on both the front and rear sides of the two water guides 2. The pins 14 are inserted into the slots 15. A handle 16 is fixed on the side of the two baffles 11 that is far apart from each other. The handle 16 is located between the two pins 14.

[0024] The two baffles 11 can act as a shield between the two water guides 2 to prevent thawing water from splashing out and polluting the environment. Furthermore, the baffles 11 and the water guides 2 are connected by a pin 14 and a slot 15. When the workers are loading or unloading materials, they only need to grasp the pin 14 and rotate it out of the slot 15, and then grasp the handle 16 to open the baffle 11. The structure is simple and the operation is very quick.

[0025] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
