Description

Technical Field

[0001] The utility model relates to the technical field of thawing devices, in particular to a thawing device used for aquatic product processing. Background Art

[0002] Aquatic product processing refers to the process of mechanically, physically, chemically or microbiologically treating aquatic products to make them into food. In order to facilitate the transportation and preservation of aquatic products, aquatic products will be frozen and must be thawed before processing.

[0003] Chinese patent CN209660318U discloses a thawing device for aquatic product processing, including a base, a control box and a thawing box. Universal wheels are provided at the four corners of the lower end of the base, and a wheel lock is provided on one side of the universal wheel. An air compressor is provided on one side of the upper end of the base, a support plate is provided on one side of the air compressor, an air heater is provided on the upper end of the support plate, the control box is provided on one side of the support plate, a display screen is embedded in one side of the upper end of the control box, and an operation panel is provided on one side of the display screen.

[0004] In the above-mentioned structure, an air compressor and an air heater are used, which enable the device to thaw aquatic products using hot air flow, so that all surfaces of the aquatic products are covered by the hot air flow, greatly improving the efficiency of aquatic product thawing. However, in actual operation, this thawing device is difficult to achieve uniform and precise temperature control due to the differences in the types, shapes, sizes and initial frozen states of aquatic products. This may cause some areas to overheat and accelerate the deterioration of the aquatic product quality, while other areas are insufficiently thawed. During the thawing process, the hot air flow will carry away moisture from the surface of the aquatic product, causing the product surface to dry out, affecting the taste and appearance of the product. Due to the direct effect of the hot air flow, the outer layer of the aquatic product may thaw faster than the inner layer, forming a so-called "thawing gradient." This uneven thawing method may cause the interior of the product to remain frozen while the outer layer is close to room temperature, affecting the overall quality of the thawed aquatic product, such as texture, taste and nutritional value. Utility Model Content

[0005] The purpose of the utility model is to provide a thawing device for processing aquatic products. Water is stored in a thawing box, and then hot air is passed into the water through a heating device to heat the water. The hot air enters the water to generate bubbles. During the heating process, the water is continuously stirred under the action of the bubbles, so that the water is heated and mixed more evenly, and the surface drying of the aquatic product caused by traditional hot air heating is avoided.

[0006] In order to solve the problems of the existing technology, the utility model provides a thawing device for aquatic product processing, comprising a bottom plate and a thawing box, wherein water for thawing is pre-stored inside the thawing box, and a heating device is installed on the bottom plate.

When the aquatic product enters the thawing box, the heating device sprays hot air into the thawing box, and the hot air enters the water in the thawing box to form bubbles. The bubbles move in the water to form a stirring effect, making the temperature distribution in the water more uniform.

[0009] Preferably, the thawing box is further provided with a product storage device for transporting aquatic products into the thawing box.

[0010] Preferably, the product storage device includes a lifting device, a flipping device, a storage frame and a support plate. The flipping device is used to flip the storage frame and pour the aquatic products in the storage frame onto an external conveying device.

DETAILED DESCRIPTION

[0024] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Reference Figures 1-6 As shown, the utility model provides: a thawing device for aquatic product processing, comprising a base plate 1 and a thawing box 2. Thawing water is pre-stored inside the thawing box 2. The thawing box 2 is made of food-grade stainless steel, which has good corrosion resistance and is easy to clean. A heating device 4 is installed on the base plate 1. The heating device 4 can generate hot air and transport the hot air to the interior of the thawing box 2. The hot air moves from the bottom to the top of the thawing box 2. The thawing box 2 is also provided with a temperature sensor for detecting the water inside the thawing box 2, monitoring and recording water temperature changes in real time. This data is processed and analyzed by a control system, providing an accurate basis for the intelligent adjustment of the heating device 4. When the aquatic product enters the thawing box 2, the heating device 4 sprays hot air into the thawing box 2. The hot air enters the water in the thawing box 2 and forms bubbles. The movement of the bubbles in the water creates a stirring effect, making the temperature distribution in the water more uniform.

[0026] The heating device 4 includes a second connecting pipe 44, which is arranged at the bottom of the thawing box 2. As a key component of the heating device 4, the second connecting pipe 44 is cleverly arranged at the bottom of the thawing box 2. This position selection ensures that the hot air can be transferred directly from the bottom to the top, effectively utilizing the natural convection characteristics of the hot air to accelerate the thawing process. A number of air jets 441 are closely arranged on the second connecting pipe 44. The second connecting pipe 44 is used to transport hot air. After the hot air is ejected from the air jets 441, it moves toward the top of the thawing box 2. The second connecting pipe 44 is in an "S" shape. The second connecting pipe 44 has a unique "S" shape design. This design not only increases the length of the pipeline, but also allows the hot air to be more fully preheated and evenly distributed inside the pipeline.

[0027] When the heating device 4 is activated, hot air is piped to the second connecting pipe 44 and ejected from the air jets 441. Due to the S-shaped design of the second connecting pipe 44 and the ingenious placement of the air jets 441, the hot air rapidly diffuses and rises as it is ejected, forming a warm airflow. This airflow continuously rises through the water, driving the surrounding water in motion, creating an effective stirring and circulation effect. Simultaneously, the heat in the hot air is rapidly transferred to the water through the contact surface between the bubbles and the water, gradually raising the water temperature to the required thawing range.

[0028] The heating device 4 also includes a heater 42, which has a heating rod for heating air installed inside. One end of the heater 42 is connected to a first connecting pipe 43, one end of the first connecting pipe 43 is connected to the second connecting pipe 44, and the other end of the heater 42 is connected to a fan 41. The fan 41 can generate gas and transport the gas to the heater 42. The fan 41 starts and inhales external air. The inhaled air enters the heater 42 and is heated by the heating rod into high-temperature hot air. The high-temperature hot air is transported to the second connecting pipe 44 through the first connecting pipe 43. In the second connecting pipe 44, the high-temperature hot air is evenly ejected through the jet port 441 and rises into the water in the thawing box 2. The ejected hot air forms bubbles in the water and produces a stirring effect, so that the water temperature is evenly increased and the thawing process of the aquatic products is accelerated.

[0029] Hot air rises from the bottom, naturally forming convection. This heating method helps evenly distribute heat in the water within the thawing chamber 2, reducing temperature gradients during the thawing process and avoiding localized overheating or uneven thawing of the aquatic product. The bubbles formed by the hot air entering the water not only increase the turbulence of the water, but also promote circulation and mixing of the water, further improving the uniformity of the water temperature. This physical stirring method eliminates the need for additional mechanical stirring equipment, reducing energy consumption and noise.

[0030] The thawing box 2 is also equipped with a product storage device 3 for conveying aquatic products into the thawing box 2. The product storage device 3 includes a lifting device 31, a tilting device 32, a storage frame 33, and a support plate 34. The tilting device 32 is used to tilt the storage frame 33. The storage frame 33 is a container for aquatic products and is designed to facilitate their storage, transportation, and tilting. The material of the storage frame 33 should be corrosion-resistant and easy to clean to ensure the hygienic safety of the aquatic products. The aquatic products in the storage frame 33 are poured onto the external conveying device. The lifting device 31 causes the tilting device 32 to move up and down within the thawing box 2, allowing aquatic products to be placed in or removed from the thawing box 2.

[0031] The lifting device 31 is the vertical movement mechanism of the product storage device 3. It is responsible for raising and lowering the flipping device 32 and the storage frame 33 above it along the height of the thawing tank 2. This allows aquatic products to be accurately delivered to the thawing tank 2 when needed and safely removed after thawing. The flipping device 32 is a key component of the product storage device 3. With the assistance of the lifting device 31, it is responsible for flipping the storage frame 33 and the aquatic products inside it out of the thawing tank 2 so that the aquatic products can be poured onto the external conveyor. This step is crucial for achieving automated unloading of aquatic products.

[0032] Side support members 341 are fixed to both sides of the top of the support plate 34 . The two side support members 341 are rotatably connected to the storage frame 33 . The storage frame 33 is provided with a plurality of through holes.

[0033] The flipping device 32 includes a second rotating drive member 321, the output end of the second rotating drive member 321 is connected to a driving wheel 322, and the driving wheel 322 is connected to a driven wheel 323 through a belt, and the driven wheel 323 is fixed on the shaft of the storage frame 33. The second rotating drive member 321 is the power source of the flipping device 32, which provides the necessary torque to drive the driving wheel 322 to rotate, and then drives the driven wheel 323 and the storage frame 33 to flip through the belt transmission system. The second rotating drive member 321 can be an electric motor, a hydraulic motor or a pneumatic motor, etc. 31 includes a lifting roller 311, which is arranged on the outside of the thawing box 2 through a bracket. A valve for draining water is also installed at the bottom of one side of the thawing box 2. A lifting rope 313 is connected to the lifting roller 311, and one end of the lifting rope 313 is interconnected with the support plate 34. The lifting device 31 also includes a first rotating drive member 312 and a guide wheel 314. The output end of the first rotating drive member 312 is interconnected with the lifting roller 311. The first rotating drive member 312 is used to rotate the lifting roller 311, and the guide wheel 314 is used to guide the lifting rope 313.

[0034] Working principle: When in use, the aquatic products to be thawed are poured into the storage frame 33, and then the first rotary driving member 312 is started. The first rotary driving member 312 rotates the lifting roller 311, and the lifting roller 311 moves the lifting rope 313, so that the storage frame 33 is placed in the thawing box 2, and then the air is heated by starting the heater 42, and the air is made to flow by starting the fan 41. After being heated by the heater 42, the air enters the second connecting pipe 44, and then the hot air is ejected from the air jet 441. The hot air enters the water to form bubbles. On the one hand, On the other hand, the water is heated and stirred continuously, so that the temperature of the water is evenly distributed, thereby preventing the outside of the aquatic product from drying out while the inside is still in a frozen state. The heating temperature should not be too high, and the specific temperature is adjusted according to the type of aquatic product. When thawing is completed, the storage frame 33 is taken out of the thawing box 2, and then the second rotating drive member 321 is started. The second rotating drive member 321 rotates the driving wheel 322, and the driving wheel 322 rotates the driven wheel 323, thereby turning the storage frame 33 over, so that the aquatic product is poured onto the conveying device and transported to the next process for processing.

[0035] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
