Description

Technical Field

[0001] This application relates to the field of seafood processing technology, and specifically discloses a drying device for seafood. Background Technology

[0002] In the processing of seafood, to extend the shelf life of seafood, it is usually necessary to dry it into dried goods. There are various drying methods, including sun drying, oven drying, and freeze drying. Among them, sun drying is the most traditional method, using sunlight and wind to evaporate the moisture in the seafood. Oven drying uses heat sources such as hot air or infrared rays to accelerate the evaporation of moisture. Freeze drying is a more advanced drying technology that uses a low-temperature vacuum environment to directly sublimate the moisture in the seafood, preserving its original color and taste.

[0003] Traditionally, the drying process of seafood using hot air is carried out in a dryer. Typically, the dryer contains multiple layers of carriers. After placing a batch of seafood on the carriers, the lid is closed, creating a relatively sealed environment. Hot air is then introduced into the dryer and exhausted through ducts. Because the seafood is placed on the carriers, some parts of the seafood are pressed against the carriers during the drying process, preventing contact with the hot air. This necessitates periodically turning and rearranging the seafood to ensure even heating and ventilation. However, turning and rearranging the seafood requires opening the dryer lid, disrupting the relatively sealed environment, leading to energy waste and reduced drying efficiency. Therefore, the inventors have provided a seafood drying device to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that in the traditional seafood drying process, the lid of the dryer needs to be opened to turn the seafood over, which leads to energy waste and reduced drying efficiency.

[0005] To achieve the above objectives, the basic solution of the present invention provides a drying apparatus for seafood, comprising:

[0006] The enclosure has a sealed door on one side wall, and air inlet and outlet chambers on the other two opposite side walls.

[0007] Several frames are installed inside the box. The box is equipped with an air inlet hopper that can connect the air inlet chamber to the inner wall of the frame. Each frame is rotatably connected to a support plate. The support plate has several gaps. An adjustment plate is slidably connected to the bottom of the frame. The adjustment plate has several top columns that can pass through the gaps of the support plate.

[0008] The drive mechanism includes a power component and a rotating shaft disposed inside the housing and driven by the power component. The rotating shaft is connected to the support plate and the adjusting plate and drives the support plate and the adjusting plate to rotate.

[0009] The bottom of the frame is provided with a wave groove with varying heights, and the bottom of the adjustment plate is provided with a support column that slides within the wave groove.

[0010] The principle and effect of this basic scheme are as follows:

[0011] This invention utilizes undulating wave grooves to create vertical sliding between the wave grooves and the support pillars during the rotation of the adjusting plate driven by the rotating shaft. This causes the top pillar on the adjusting plate to extend upwards through the gap in the support plate. When the top pillar is below the support plate, seafood is placed on the support plate and dried through the gaps in the support plate. In this state, the seafood above the gaps can fully contact the hot air for drying, while the area where the seafood is in contact with the support plate cannot. After the top pillar extends upwards, the seafood directly contacts the top of the pillar, and the pillar extends upwards to the position originally above the gaps. This creates perforations between the remaining areas of the seafood and the support plate, allowing hot air to flow and dry the seafood evenly. Compared to existing technologies, this invention eliminates the need to open the sealed door to turn and arrange the seafood, effectively reducing heat energy waste during the drying process and improving drying efficiency. It solves the problem of energy waste and reduced drying efficiency caused by opening the dryer lid to turn the seafood during traditional seafood drying processes.

[0012] Furthermore, the wave groove includes symmetrically arranged upper convex parts, lower concave parts, and a connecting part between the upper convex parts and the lower concave parts. The height difference between the upper convex parts and the lower concave parts is greater than the thickness of the support plate. By providing the upper convex parts, lower concave parts, and connecting parts, when the support column slides along the wave groove, it is convenient to drive the adjusting plate to move vertically, so that the top column is located below the support plate or extends upward through the support plate.

[0013] Furthermore, the support pillars are two in number and symmetrically arranged around the center of the adjusting plate, and during the rotation of the adjusting plate, the bottom of the support pillars is at the same horizontal height as the wave groove. This symmetrical arrangement ensures that the horizontal height of the support pillars is relatively uniform, thereby preventing positional deviations during the vertical movement of the adjusting plate.

[0014] Furthermore, the bottom surface of the inner frame is symmetrically provided with arc-shaped plates, and the upper convex portion of the wave groove is formed between adjacent arc-shaped plates. The lower concave portion of the wave groove is embedded below the bottom surface of the inner frame. This arrangement effectively reduces the space occupied by the wave groove, making the structure inside the frame more compact and thus able to accommodate more seafood.

[0015] Furthermore, the support plate includes an inner plate connected to the rotating shaft, an outer plate rotatably connected to the inner wall of the frame, and a plurality of connecting ribs staggered between the inner and outer plates, forming the gap between the connecting ribs. This arrangement not only allows for a larger gap between the connecting ribs to facilitate hot air circulation, but also maintains sufficient structural strength of the support plate to enable overall rotation.

[0016] Furthermore, the upper surface of the frame is provided with a support ring that connects to the end of the outer plate, and the inner wall of the frame is rotatably connected to the outer wall of the support ring. The support ring can strengthen the connection structure during the rotation of the support plate, and the support ring and the inner wall of the frame cooperate with each other to limit the rotation of the entire support plate.

[0017] Furthermore, the support ring has a through groove on its side wall located below the outer plate. The frame covers the through groove, and the air inlet is located on the side wall of the frame and communicates with the through groove. This arrangement prevents the hot air from coming into contact with the seafood again after drying, thus avoiding water vapor in the hot air adhering to the surface of the seafood and affecting the drying effect.

[0018] Furthermore, a gap is formed between the outer wall of the frame and the inner wall of the box, and the outer wall of the frame is provided with several support rods that connect to the inner wall of the box. This method not only facilitates the fixing of the frame, but also facilitates the outflow of hot air.

[0019] Furthermore, when the adjusting plate moves to its highest position, its horizontal height is lower than that of the through slot. This is to prevent the adjusting plate from blocking the through slot and affecting the normal flow of hot air.

[0020] Based on the same inventive concept, this invention provides a method for drying seafood, including drying seafood using the aforementioned drying equipment. Compared with the prior art, this method does not require opening the sealed door to turn and arrange the seafood, which can effectively reduce heat energy waste during the drying process and improve the drying efficiency of seafood. It solves the problem of energy waste and reduced drying efficiency caused by opening the dryer lid to turn the seafood in the traditional seafood drying process. Attached Figure Description

[0028] A drying device for seafood, implementing, for example Figure 1 As shown, the device includes a housing 1, multiple frames 9 disposed within the housing 1, a support plate and an adjusting plate 22 disposed within the frames 9, and a drive mechanism for rotating the support plate and the adjusting plate 22, as detailed below:

[0029] Box 1: The front side wall of box 1 is equipped with a sealed door 2. The left and right side walls of box 1 are respectively equipped with an air inlet chamber 7 and an air outlet chamber 8. The bottom of box 1 is equipped with a support 3. The air inlet chamber 7 and the air outlet chamber 8 are respectively connected to an air inlet pipe 13 and an air outlet pipe 14. An electric heating wire is installed in the air inlet pipe 13. The air inlet pipe 13 is connected to an air pump. The air inlet end of the air pump is equipped with a filter screen. Under the action of the air pump, the air enters the air inlet pipe 13 after being filtered by the filter screen and then enters the air inlet chamber 7. The air outlet pipe 14 is connected to an adsorption box. The adsorption box is filled with multiple layers of water-absorbing layer. Common desiccant can be used for the water-absorbing layer. After the air in the air outlet pipe 14 is adsorbed by the adsorption box, it is reconnected to the air inlet end of the air pump, thereby achieving the recycling of hot air.

[0030] Frame 9: as Figure 1 and Figure 2 As shown, several frames 9 are vertically arranged, and a gap is formed between the outer wall of the frame 9 and the inner wall of the box 1. The outer wall of the frame 9 is provided with several support rods that are connected to the inner wall of the box 1.

[0031] Support plate: The support plate includes an inner plate 15, an outer plate 16, and a plurality of connecting ribs 17 staggered between the inner plate 15 and the outer plate 16. The connecting ribs 17 are made of steel bars, and gaps are formed between the connecting ribs 17. The upper surface of the frame 9 is provided with a support ring 10 connected to the end of the outer plate 16. The inner wall of the frame 9 is rotatably connected to the outer wall of the support ring 10. The side wall of the support ring 10 is provided with a through groove 19 located below the outer plate 16. Figure 3 As shown, the through groove 19 divides the support ring 10 into an upper ring body 1002 and a lower ring body 1001. Multiple connecting posts 20 are arranged between the upper ring body 1002 and the lower ring body 1001 for connection. The inner wall of the frame 9 covers the through groove 19, and the side wall of the frame 9 is provided with an air inlet hopper 11. The air inlet hopper 11 is connected between the through groove 19 and the air inlet chamber 7. The other side of the box body 1 is provided with an air outlet 12 that is connected to the air outlet chamber 8.

[0032] Adjustment plate 22: such as Figure 4 As shown, the adjusting plate 22 is located inside the frame 9 and below the support plate. The adjusting plate 22 is provided with several top posts 18 that can pass through the gaps in the support plate. When the adjusting plate 22 moves to the top, the horizontal height of the adjusting plate 22 is lower than the horizontal height of the through groove 19.

[0033] The bottom of the frame 9 is provided with a wave groove 21 with varying heights. The bottom of the adjusting plate 22 is provided with a support column that slides in the wave groove 21. Specifically, the wave groove 21 includes an upper convex part, a lower concave part and a connecting part provided between the upper convex part and the lower concave part, which are symmetrically arranged. The bottom surface of the frame 9 is provided with an arc plate, and the upper convex part of the wave groove 21 is formed between adjacent arc plates. The lower concave part of the wave groove 21 is embedded below the bottom surface of the frame 9. The height difference between the upper convex part and the lower concave part is greater than the thickness of the support plate. There are two supports, which are symmetrically arranged along the center of the adjusting plate 22. During the rotation of the adjusting plate 22, the bottom of the supports is at the same horizontal height of the wave groove 21.

[0034] Drive mechanism: such as Figure 1 As shown, the drive mechanism includes a power component, a reducer 5 connected to the output shaft of the power component, and a rotating shaft 6 located inside the housing 1 and driven by the output end of the reducer 5. The power component can be a motor 4. The rotating shaft 6 is fixedly connected to the inner plate 15 of the support plate to drive the support plate to rotate. The rotating shaft 6 is splinedly connected to the adjusting plate 22 to drive the adjusting plate 22 to rotate and allow the adjusting plate 22 to slide vertically.

[0035] In this embodiment, after placing the seafood on each support plate, the staff closes the sealing door 2. By energizing the electric heating wire and turning on the air pump and motor 4, the seafood can be dried. Air, driven by the air pump, passes through a filter screen and enters the air inlet pipe 13, then the air inlet chamber 7, and through the channel 19 to the area below the support plate. It then contacts the seafood through the gaps in the support plate. Since the drying temperature of seafood is typically 30-40°C, the hot air still contains water vapor, and the temperature is not high. This causes water vapor to easily adhere to the surface of the seafood upon re-contact. In this embodiment, a frame 9 is used to isolate the hot air drying the seafood on each support plate, allowing the dried air to flow out through the holes or air outlet 12. Furthermore, the drive mechanism causes the seafood on the support plate to rotate within the chamber 1, ensuring more even heating of the seafood in all positions. Furthermore, the wave groove 21 causes the adjusting plate 22 to slide vertically as the rotating shaft 6 drives the adjusting plate 22 to rotate. This allows the top column 18 on the adjusting plate 22 to extend upwards through the gap in the supporting plate. When the top column 18 is below the supporting plate, the seafood is placed on the supporting plate and dried through the gap in the supporting plate. In this state, the seafood above the gap can fully contact the hot air for drying, while the seafood in contact with the supporting plate cannot fully contact the hot air. After the top column 18 is pushed upwards, the seafood directly contacts the top of the column, and the column is pushed upwards to the position originally above the gap. This creates a perforation between the remaining parts of the seafood and the supporting plate, allowing the hot air to flow and dry the seafood. This ensures that all parts of the seafood can be dried evenly with hot air. After drying, the sealing door 2 is opened, and the dried seafood is taken out.

[0036] Based on the same inventive concept, the present invention provides a method for drying seafood, comprising drying seafood using the aforementioned drying equipment, the steps of which are as follows:

[0037] Step S001: After placing the seafood on each support plate, close the sealing door 2. By energizing the electric heating wire and turning on the air pump and motor 4, the air enters the air inlet pipe 13 after being filtered by the filter screen and then enters the air inlet chamber 7. It then enters the support plate below through the through groove 19 and comes into contact with the seafood through the gaps on the support plate.

[0038] In step S002, the frame 9 isolates the hot air used to dry the seafood on each support plate, allowing the dried hot air to flow out through the gaps or air outlets 12. Driven by the drive mechanism, the seafood on the support plates rotates within the housing 1, ensuring more even heating of the seafood in each position. Furthermore, the wave groove 21, during the rotation of the adjusting plate 22 driven by the rotating shaft 6, causes the adjusting plate 22 to slide vertically, resulting in the top post 18 on the adjusting plate 22 extending upwards through the gap in the support plate. When the top post 18 is located at the support... When the seafood is placed under the support plate, it is dried through ventilation through the gaps in the support plate. In this state, the seafood above the gap can fully contact the hot air for drying, while the seafood in contact with the support plate cannot fully contact the hot air. After the top column 18 is pushed upward, the seafood directly contacts the top of the column, and the column is pushed upward to the position that was originally above the gap. This creates a perforation between the remaining parts of the seafood and the support plate, allowing the hot air to flow and dry the seafood. As a result, all parts of the seafood can be dried evenly with hot air.

[0039] Step S003: After drying is complete, open the sealed door 2 and take out the dried seafood.

[0040] Compared with the prior art, the present invention does not require opening the sealed door 2 to turn and arrange the seafood, which can effectively reduce the heat energy waste in the drying process and improve the drying efficiency of seafood. It solves the problem that in the traditional seafood drying process, the dryer lid needs to be opened to turn the seafood, resulting in energy waste and reduced drying efficiency.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
