Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0020] like Figure 1-3As shown: This embodiment provides a defrosting machine, including a defrosting box 100, made of food-grade 304 stainless steel.

It is detachably fixed between the two vertical parts of the U-shaped fixing plate by bolts, forming an upper and lower two-layer placement cavity with the support plate 302. When the items to be defrosted are placed in the placement cavity, the filter plate 400 can evenly distribute the weight of the food and prevent the food from deforming due to local stress. At the same time, it allows the melted water to penetrate smoothly to the support plate 302 and drip down to the bottom of the defrosting box 100 through the drain hole. The items to be thawed are placed in the placement cavity formed by the filter plate 400 and the storage frame 300. The lifting component 200 can lift the storage frame 300. This utility model can conveniently and labor-savingly lift the storage frame 300 through the lifting component 200, so as to drip off the water remaining on the surface of the thawed object. At the same time, it is easy to remove the material and fill it with the object to be thawed for subsequent thawing operations. The operation is more convenient and greatly improves the thawing effect and efficiency of the material.

[0021] According to one embodiment of the present invention, such as Figure 1-3As shown, the storage frame 300 includes a U-shaped fixing plate 301 and a support plate 302 disposed on the outer side of the bottom of the two vertical parts of the U-shaped fixing plate 301. The support plate 302 has multiple drainage holes. The U-shaped fixing plate, the support plate 302, and the filter plate 400 are all made of food-grade 304 stainless steel to ensure safety in contact with food. The U-shaped fixing plate has a "U" shaped structure. The length of its horizontal part is adapted to the inner diameter of the defrosting box 100, and the height of its two vertical parts matches the length of the guide groove 101. The outer wall is tightly fitted to the inner wall of the guide groove 101, allowing it to slide smoothly along the guide groove 101 without jamming. The support plate 302 is welded to the outer side of the bottom of the two vertical parts of the U-shaped fixing plate. Multiple drainage holes are evenly distributed on the plate. The drainage holes are distributed in a regular hexagonal pattern, which can ensure that melted water is drained quickly, prevent food debris from falling, and support the weight of the food.

[0022] According to another embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the lifting assembly 200 includes a linear slide 201 disposed on the upper side wall of the defrosting box 100. A support rod 202 is disposed on the slider of the linear slide 201. The support rod 202 is located between the two vertical parts below the horizontal part of the U-shaped fixing plate 301, and the U-shaped fixing plate 301 is slidably disposed on the support rod 202. The end of the support rod 202 is provided with an external thread, and a locking nut 303 is threadedly connected to the end of the support rod 202. The linear slide 201 is an RSH100 model electric linear slide 201 manufactured by Shenzhen Leisai Intelligent Control Co., Ltd.

The support rod 202 is made of 304 stainless steel, with a diameter of 12mm. One end is welded to the slider of the linear slide 201, and the other end extends to the space between the two vertical sections below the horizontal part of the U-shaped fixing plate. The outer diameter of the support rod 202 is adapted to the distance between the two vertical sections of the U-shaped fixing plate. The U-shaped fixing plate can slide horizontally along the support rod 202, making it easy to adjust the horizontal position of the storage frame 300 in the defrosting box 100 according to the size of the food. The locking nut 303 is made of 304 stainless steel, and its internal thread matches the external thread at the end of the support rod 202. The outer side of the nut is provided with anti-slip texture, which can be manually tightened without tools. When tightened, the U-shaped fixing plate can be pressed against the support rod 202 to fix the horizontal position of the storage frame 300 and prevent the storage frame 300 from sliding due to vibration during defrosting. After loosening, the position can be flexibly adjusted to accommodate food of different sizes.

[0023] Another embodiment of the lifting assembly is as follows: the lifting assembly includes a telescopic push rod disposed on the upper part of the defrosting box 100. The telescopic push rod is an electric push rod or a hydraulic push rod. The output rod end of the telescopic push rod is provided with a lifting plate, and the lifting plate is fixedly connected to the side wall of the storage frame 100.

[0024] According to another embodiment of the present invention, such as Figure 1 and Figure 3 As shown, the defrosting machine also includes a heater 102 located at the bottom of the defrosting chamber 100. A disc-shaped heating wire electrically connected to the heater 102 is located at the bottom of the defrosting chamber 100. The heater 102 is an AKX-220V / 1500W waterproof heater manufactured by Jiangsu Aikesheng Electric Co., Ltd., and it has dual protection functions— First, it features overheat protection, automatically cutting off power when the heating temperature exceeds 80℃ to prevent damage to the equipment or spoilage of food due to excessive heat. Second, it has waterproof protection with an IPX4 waterproof rating, allowing direct installation in humid environments on the lower outer side of the defrosting box 100 without causing short circuits due to melted water splashing. The heater 102 is fixed with bolts and electrically connected to the disc heating wire via a high-temperature resistant wire of model AF200, providing stable heat to the disc heating wire. The disc heating wire is made of nickel-chromium alloy material of grade Cr20Ni80, which has high thermal conductivity, high temperature resistance, strong oxidation resistance, and long service life. The heating wire is spiral-shaped and fixed to the lower inner side of the defrosting box 100 by ceramic insulators, covering more than 90% of the bottom area of ​​the defrosting box 100. Heat can be evenly diffused to the air and bottom of the defrosting box 100 through thermal radiation and thermal conduction, avoiding localized overheating and achieving uniform defrosting of food.

[0025] The defrosting machine also includes a temperature display 103, which is a JQ-LED-01 digital temperature display manufactured by Shanghai Jinquan Electronic Technology Co., Ltd. This display has three core functions: first, real-time display with a measurement range of -50℃ to 100℃ and an accuracy of ±0.5℃; the LED display brightness is adjustable, ensuring clear readings in both strong and weak light environments; second, an alarm function, allowing users to set an alarm temperature range via buttons, triggering an audible and visual alarm when the temperature exceeds the range; and third, data memory, storing temperature data for the past 7 days for easy tracking of the defrosting process. The probe of the temperature display 103 is fixed to the middle of the inner wall of the defrosting chamber 100 with clamps to ensure that the detected temperature matches the actual ambient temperature of the food. The display screen is bolted to the upper part of the outer wall of the defrosting chamber 100, at eye level for easy real-time monitoring.

[0026] How to use this utility model: First, it needs to be clarified that the defrosting machine involved in this utility model is mainly used for defrosting various kinds of food. This utility model takes the defrosting of meat, especially vacuum-packed beef and mutton rolls, as an example to explain its working principle and usage method in detail. The working principle is as follows: This invention achieves efficient defrosting through a synergistic mechanism of "lifting and lowering adjustment - uniform heating - water drainage protection - precise temperature control": First, after the power is turned on, the heater 102 is powered on and delivers heat to the disc heating wire. The disc heating wire spreads the heat evenly into the defrosting chamber 100 through thermal radiation and thermal conduction, so that the temperature inside the chamber gradually rises to the optimal defrosting range of 15-25℃. The probe of the temperature display instrument 103 detects the temperature inside the chamber in real time and transmits the data to the display screen, so that the operator can intuitively grasp the temperature changes. Secondly, by pressing the "Up" button on the control panel of the linear slide 201, the linear slide 201 drives the support rod 202 to rise. The support rod 202 simultaneously drives the storage frame 300 to slide along the guide groove 101 to the top opening of the defrosting box 100. At this time, the operator can easily put the food to be defrosted into the placement cavity of the storage frame 300, that is, the cavity formed between the filter plate 400 and the support plate 302. If the food has a special size, the locking nut 303 can be loosened, and the U-shaped fixing plate can be slid along the support rod 202 to adjust the horizontal position of the storage frame 300 to ensure that the food is completely placed in the box. After adjustment, the locking nut 303 can be tightened to fix it. Then, press the "lower" button on the linear slide 201, set the lowering height, and the linear slide 201 will drive the storage frame 300 to descend smoothly along the guide groove 101 to the target position. During the defrosting process, the melted water generated on the surface of the food passes through the perforations of the filter plate 400 and the drain holes of the support plate 302 in sequence, and drips to the bottom of the defrosting box 100 to prevent the food from soaking. Meanwhile, the temperature display 103 continuously monitors the temperature inside the chamber. If the temperature exceeds the set range, it will immediately issue an audible and visual alarm. The operator can adjust the power through the control panel of the heater 102 to ensure temperature stability. After thawing, press the "Up" button on the linear slide 201, and the storage box 300 will rise to the top. The operator can then directly remove the food without bending over or going deep into the box. If continuous operation is required, new food to be thawed can be loaded directly at the top, and the above process can be repeated to improve work efficiency. The usage method is as follows: Preparations before thawing: Cleaning and Inspection: First, wipe the inner wall of the defrosting chamber 100, the storage frame 300, the filter plate 400, and the support plate 302 with clean water to remove residual stains; if there are stubborn stains, wipe them with a neutral detergent, then rinse them with clean water, and finally wipe them dry with a sterile cloth; check the connection status of each component—whether the welding joint between the linear slide 201 slider and the support rod 202 is firm, whether the heater 102 and the disc heating wire are damaged, and whether the temperature display probe 103 is loose, to ensure there are no safety hazards; Power-on debugging: Connect the 220V power supply, turn on the temperature display 103 and heater 102 switches, set the alarm range of the temperature display 103, and preheat the defrosting chamber to about 100 to 15℃; test the lifting function of the linear slide 201, raise the storage frame 300 to the top and lower it to the middle respectively, and check whether the sliding is smooth and whether the position memory is accurate; test the power adjustment function of the heater 102 to ensure that the power can be smoothly switched between 500-1500W. Placement of ingredients: Lifting storage frame 300: Press the "Up" button on the control panel via the linear slide 201. The storage frame 300 will rise to the top along the guide groove 101. After the slider stops moving, lay the food to be thawed flat in the placement cavity of the storage frame 300. Take care to avoid stacking the food. The weight of a single batch should not exceed 30kg. Adjusting the position: If the food is large, loosen the locking nut 303 at the end of the support rod 202 and slide the U-shaped fixing plate horizontally along the support rod 202 so that the food is completely inside the defrosting box 100 and no part of it protrudes from the box wall; after adjustment, tighten the lock nut clockwise until it can no longer be rotated. Initiate defrosting: Lowering the storage box 300: Press the "Lower" button on the linear slide 201, input the lowering height through the control panel, and the slide will drive the storage box 300 to descend smoothly and stop automatically after reaching the target position; Adjusting the temperature: Observe the reading on the temperature display 103. If the temperature inside the chamber is below 15℃, increase the power through the control panel of the heater 102; if the temperature is above 20℃, decrease the power to ensure that the temperature is maintained in the range of 15-25℃. Drainage monitoring: Regularly check the water accumulation at the bottom of the defrosting chamber 100. If there is a lot of water, stop the equipment, open the bottom drain valve to drain the water, and avoid excessive water accumulation affecting the heating efficiency. Thawing monitoring and completion: Real-time monitoring: During the thawing process, the operator needs to check the temperature display 103 every 10 minutes to confirm that the temperature is within the set range; if an audible and visual alarm occurs, immediately investigate the cause—if it is a high temperature alarm, check whether the power of the heater 102 is too high or whether the disc heating wire is abnormal; if it is a low temperature alarm, check whether the heater 102 is powered off or whether the wires are poorly connected, and restart after troubleshooting; Determine if thawing is complete: Determine the thawing time based on the type and size of the food, and at the same time observe the state of the food. If there is no frost on the surface and no hard core when pressed by hand, the thawing is considered complete. Removing ingredients: Press the "Up" button on the linear slide 201, and the storage box 300 will rise to the top. The operator can then directly remove the ingredients by hand or with a tool and place them into the subsequent processing container.

[0027] Cleaning and storage: Power-off cleaning: Turn off the power to all equipment and unplug the plugs; remove the filter plate 400 of the storage frame 300, and rinse the filter plate 400, support plate 302 and U-shaped fixing plate with clean water to remove residual melted water and food debris; wipe the inner wall of the defrosting box 100, the temperature display probe 103 and the display screen with a sterile cloth to ensure that there is no moisture residue; Storage and maintenance: Reinstall the cleaned filter plate 400 back into the storage frame 300, adjust the storage frame 300 to the center of the defrosting box 100, and tighten the locking nut 303; cover the top of the defrosting box 100 with the dust cover; check the condition of each component. If the linear slide 201 is found to be stuck, a small amount of food-grade grease can be applied to the guide groove 101 to extend its service life; finally, store the equipment in a dry and ventilated indoor environment to avoid moisture and rust.

[0028] This invention enables centralized placement of items to be thawed via the storage frame 300. Simultaneously, the lifting component 200 enables automatic and efficient retrieval of thawed items within the storage frame 300. This makes operation more convenient and efficient, solving the problem that most thawing machines have their storage structure fixed in the lower part of the box, requiring operators to bend over or reach into the box to retrieve food. This not only increases labor intensity but also easily damages food due to bumps against the box walls, and the retrieval process is time-consuming, seriously affecting operational efficiency.

[0029] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
