Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a high-temperature sterilization device for bird's nest and fish maw products. Background Technology

[0002] Currently, vertical high-temperature sterilizers are used for heat sterilization of food. The pre-filled bird's nest and fish maw products (filled in high-temperature resistant glass jars) are placed into the sterilizer through sterilization baskets, hot water is introduced, and the pot is covered and sealed. Steam is then introduced, and the water temperature rises from the preheating temperature to the set sterilization temperature within 3-5 minutes. However, existing high-temperature sterilizers suffer from uneven temperature distribution. The glass jars may crack due to excessive pressure difference caused by rapid steam heating. Bird's nest and fish maw typically contain liquid, and uneven heating can easily lead to clumping of the gelatinous substance or destruction of nutrients. Furthermore, existing sterilization baskets are usually square, while the sterilizer body is designed with a circular cross-section to withstand pressure, resulting in low utilization of the internal space. Utility Model Content

[0003] The purpose of this utility model is to provide a high-temperature sterilization device for bird's nest and fish maw products, so as to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: First, this utility model provides a high-temperature sterilization device for bird's nest and fish maw products, comprising:

[0005] The pot body is equipped with an air pressurization pipe, and the pot body has a jacket for steam introduction.

[0006] A pot lid, which is detachably mounted on the pot body and forms a sealed sterilization space inside the pot body, and the pot lid is provided with a water inlet pipe;

[0007] A rotating column is located at the center of the pot body, and its bottom is connected to a rotating motor via a rotating bearing. The rotating motor is located at the lower part of the pot body. The outer wall of the rotating column is provided with at least two sliding grooves vertically downward from the top. The sliding grooves are provided with transverse grooves at fixed distances in the vertical direction. The transverse grooves are located on the same side of the sliding grooves, and the ends of the transverse grooves away from the sliding grooves extend downward to form an assembly groove.

[0008] The rotating tray is disc-shaped and is used to place the jar containing bird's nest and fish maw. The center position is provided with an assembly hole for fitting onto the rotating column. At least two protrusions are provided on the inner wall of the assembly hole. The protrusion slides into the top of the slide groove and rotates around the central axis when it slides to one of the transverse grooves. The protrusion slides into the assembly groove through the transverse groove and is fixed.

[0009] In this technical solution, after placing the container of bird's nest and fish maw requiring high-temperature sterilization into the pot, the pot lid is closed and sealed. Water is introduced through the inlet pipe, ensuring the container is completely submerged in water. The water is indirectly heated by steam, utilizing the thermal conductivity of water to evenly heat the product. Simultaneously, pressure is increased through an air pressurization pipe, raising the water temperature to the sterilization temperature (e.g., 121℃, with pressure and temperature matched at 0.1MPa gauge pressure corresponding to 121℃), entering a constant-temperature sterilization stage, maintaining constant water temperature and pressure (e.g., 30 minutes). During the above process, a rotating column is controlled by a rotary motor, causing the rotating tray and container to slowly rotate in the water, increasing the flow of hot water within the pot, ensuring uniform water temperature, and evenly distributing the water flow around the container to avoid localized overheating or cold spots. Uniform temperature significantly reduces the risk of glass jar breakage.

[0010] Compared to traditional methods, the high-temperature sterilization device provided by this invention achieves a water temperature of 121℃ through pressurization control, making it suitable for scenarios requiring uniform heating and controllable pressure (such as bird's nest and fish maw products packaged in glass jars). Furthermore, the rotating tray agitates the water within the pot, improving water flow and ensuring uniform water temperature. This evenly distributes the water around the jar, preventing localized overheating or cooling, and significantly reducing the risk of glass jar breakage. The rotating tray's disc shape matches the cylindrical design of the pot, maximizing the utilization of internal space.

[0011] As an extension of the above solution, the rotating column is provided with a water inlet cavity, and the water inlet cavity has several water outlet holes that penetrate the cavity wall radially along the central axis. The bottom of the water inlet cavity is provided with a water inlet channel, which passes through the center of the rotating bearing and communicates with the connecting cavity. The outside of the connecting cavity is connected to a first circulating water pipe, and a second circulating water pipe is provided at the upper part of the middle of the pot body.

[0012] In this extended design, the water inlet and outlet of the rotating column further improve the water flow inside the pot. At the same time, water circulation inside the pot is achieved through the first and second circulating water pipes. The water circulation is continuous, the water flow is evenly distributed, dead corners are avoided between the tanks, and each position is heated evenly, eliminating cold spots (such as gaps between the rotating tray or the tanks).

[0013] As an extension of the above solution, the opening where the transverse groove connects with the slide groove is open. The open design means that the end edge of the transverse groove is chamfered or rounded, thus widening the end of the transverse groove. This provides guidance for the protrusion to slide into the transverse groove when the rotating tray slides down to the position of the transverse groove, facilitating the rotation and engagement of the protrusion into the assembly slot.

[0014] As an extension of the above solution, the rotating tray includes a base plate and an annular column disposed at the center of the base plate. The inner wall of the annular column forms an assembly hole, and the inner wall of the annular column fits against the outer wall of the rotating column. The fit between the annular column and the rotating column improves the stability of the rotating tray. By utilizing the fit between the inner annular wall and the outer circular wall, the rotating tray can be firmly fixed to the rotating column.

[0015] As an extension of the above solution, the bottom plate is provided with several annular partitions, and the area between the annular partitions is used to place the jar containing bird's nest and fish maw. Several through holes or through grooves are arranged on the annular partitions.

[0016] The annular baffles in this extended design can better separate the tanks, allowing the tanks to be placed in the annular areas between the baffles. The annular baffles are provided with through holes or grooves to allow water to flow between the two annular areas, thereby improving the uniformity of water temperature.

[0017] As an extension of the above solution, the base plate is a plate with a honeycomb structure, and a reinforcing frame is provided below the plate. The honeycomb structure can avoid dead corners between the tank and the base plate, ensure uniform heating at each location, and eliminate cold spots, such as gaps between the rotating tray or the bottom of the tank. The reinforcing frame can effectively enhance the load-bearing capacity of the rotating tray.

[0018] As an extension of the above solution, the top of the annular column is provided with a lifting ring. The rotating tray is then lifted into the pot body using the lifting device, making the operation convenient.

[0019] As an extension of the above solution, the inner wall of the pot is wrapped with a cooling coil, and the two ends of the cooling coil pass through the wall of the pot and are connected to an external cooling system.

[0020] This extended solution enters the cooling stage after the constant temperature sterilization stage. The steam is turned off and the cooling system is turned on. The water in the pot is cooled through the cooling coil. Cooling water is introduced into the cooling coil, and at the same time, sterile compressed air is introduced through the air pressurization pipeline to maintain the pressure inside the pot slightly higher than the external atmospheric pressure, so as to prevent the container from rupturing due to excessive pressure difference between the inside and outside.

[0021] As an extension of the above solution, a drain pipe is provided at the bottom of the pot. The drain pipe can remove impurities and excess water during the sterilization stage. The water level is controlled by the drain pipe to avoid excessive water increasing the energy consumption for heating. When the pressure inside the pot may exceed the safety valve setting value, the drain pipe can be used in conjunction with the pressure relief pipe to quickly relieve pressure by discharging some water or gas.

[0022] As an extension of the above solution, the lid is equipped with a pressure gauge, the pressure probe of which extends into the sterilization space inside the pot. The lid also has a pressure relief pipe. During the pressurization and cooling phase, the pressure inside the pot needs to be monitored using the pressure gauge to prevent the glass jar from exploding due to excessive pressure difference between the inside and outside.

[0033] Reference Figures 1 to 4 The following are several embodiments of a high-temperature sterilization device for bird's nest and fish maw products according to this utility model.

[0034] like Figures 1-4 As shown, in some embodiments, a high-temperature sterilization device for bird's nest and fish maw products includes:

[0035] The pot body 100 is provided with an air pressurization pipe 110, and the pot body 100 has a jacket 120 for steam to be introduced to indirectly heat the water in the pot.

[0036] A pot lid 200 is detachably mounted on the pot body 100 and forms a sealed sterilization space inside the pot with the pot body 200. A water inlet pipe 210 is provided on the pot lid 200.

[0037] A rotating column 300 is located at the center of the pot body 100, and its bottom is connected to a rotating motor 400 via a rotating bearing 410. The rotating motor 400 is located at the lower part of the pot body 100. The outer wall of the rotating column 300 is provided with at least two sliding grooves 310 vertically downward from the top. The sliding grooves 310 are provided with transverse grooves 320 at fixed distances in the vertical direction. The transverse grooves 320 are located on the same side of the sliding grooves 310. The end of the transverse grooves 320 away from the sliding grooves 310 extends downward to form an assembly groove 330.

[0038] The rotating tray 500 is disc-shaped and is used to place the jar 600 containing bird's nest and fish maw. The center position is provided with an assembly hole 510 for fitting onto the rotating column 300. At least two protrusions 520 are provided on the inner wall of the assembly hole 510. The protrusions 520 slide into the top of the slide groove 310 and rotate around the central axis when they slide into one of the transverse grooves 320. The protrusions 520 slide into the assembly groove 330 through the transverse groove 320 and are fixed.

[0039] In this embodiment, after the container of bird's nest and fish maw is installed on the rotating tray, the protrusion is aligned with the slide groove and slid in using the assembly hole and rotating column. When it slides to a designated height, the rotating tray is controlled to rotate, and the protrusion slides through the transverse groove into the assembly groove. At this time, the rotating tray is fixed on the rotating column. In the above operation, the rotating tray can be placed into the pot by mechanical lifting. When it slides down the slide groove to a designated position, the mechanical lifting is controlled to rotate, causing the rotating tray to rotate and thus controlling the protrusion to slide into the assembly groove and be fixed. In the removal operation, the rotating tray is first lifted by the mechanical lifting, so that the protrusion is raised to the same height as the transverse groove. The mechanical lifting is then controlled to rotate, causing the rotating tray to rotate, slide out of the transverse groove and into the slide groove, and then the rotating tray can be removed from the pot by straight lifting.

[0040] After placing the container of bird's nest and fish maw that requires high-temperature sterilization into the pot, cover and seal the pot, control the water inlet pipe to ensure that the container is completely immersed in water, and indirectly heat the water with steam to evenly heat the product by utilizing the thermal conductivity of water. At the same time, pressurization is carried out through the air pressurization pipe, which provides compressed air or steam through an external air compressor or steam compressor to inject compressed air or steam into the pot to increase the pressure.

[0041] The water temperature is increased to the sterilization temperature (e.g., 121°C, with pressure matched to temperature at 0.1 MPa gauge pressure corresponding to 121°C), entering the constant temperature sterilization stage, maintaining constant water temperature and pressure (e.g., 30 minutes). During this process, a rotary motor controls the rotation of the rotating column, causing the rotating tray and tank to slowly rotate in the water, increasing the flow of hot water within the tank, ensuring uniform water temperature, and distributing the water flow evenly around the tank to avoid localized overheating or cold spots. Uniform temperature significantly reduces the risk of glass jar breakage. In some specific embodiments, by setting the rotary motor to rotate in both directions, the uniformity of water temperature can be further improved.

[0042] This embodiment uses pressurization control to achieve a water temperature of 121℃, suitable for scenarios requiring uniform heating and controllable pressure (such as glass jars of bird's nest and fish maw). Furthermore, the rotating tray agitates the water within the pot, improving its fluidity and ensuring uniform temperature distribution. This evenly distributes the water around the jar, preventing localized overheating or cooling, and significantly reducing the risk of glass jar breakage. The rotating tray's disc shape matches the cylindrical design of the pot, maximizing the utilization of internal space.

[0043] like Figure 1 and Figure 3As shown, in some embodiments, the rotating column 300 is provided with a water inlet cavity 340, the water inlet cavity 340 is provided with a plurality of water outlet holes 350 along the radial direction of the central axis through the cavity wall, the bottom of the water inlet cavity 340 is provided with a water inlet channel 360, the water inlet channel 360 passes through the center of the rotating bearing 410 and communicates with the connecting cavity 370, the outside of the connecting cavity 370 is connected to a first circulating water pipe 380, and a second circulating water pipe 390 is provided at a position slightly above the middle of the pot body 100.

[0044] In this embodiment, the water inlet and outlet of the rotating column further improve the water flow inside the pot. At the same time, the water circulation inside the pot is realized through the first and second circulating water pipes. The water circulation is continuous and the water flow is evenly distributed, avoiding dead corners between tanks, ensuring that each position is heated evenly, and eliminating cold spots (such as gaps between rotating trays or tanks).

[0045] like Figure 2 In some embodiments, the opening where the transverse groove 320 connects to the slide groove 310 is open. This open design means that the end edge of the transverse groove is chamfered or rounded, thus enlarging the end of the transverse groove. This provides guidance for the protrusion to slide into the transverse groove when the rotating tray slides down to the position of the transverse groove, facilitating the rotation and engagement of the protrusion into the assembly slot.

[0046] like Figure 1 and 4 As shown, in some embodiments, the rotating tray 500 includes a base plate 530 and an annular post 540 disposed at the center of the base plate 530. The inner wall of the annular post 540 forms an assembly hole 510, and the inner wall of the annular post 540 is in contact with the outer wall of the rotating post 300. In this embodiment, the stability of the rotating tray is improved by fitting the annular post to the rotating post. By utilizing the contact between the inner annular wall and the outer circular wall, the rotating tray can be firmly fixed to the rotating post.

[0047] like Figure 4 As shown, in some embodiments, the base plate 530 is provided with a plurality of annular partitions 550, and the area between the annular partitions 550 is used to place the jar 600 containing bird's nest and fish maw. The annular partitions 550 are provided with a plurality of through holes or through grooves (not shown in the figure).

[0048] The annular partition in this embodiment can better separate the tank, allowing the tank to be placed in the annular area between the annular partitions. The annular partitions are provided with through holes or through grooves to allow water to flow between the two annular areas, thereby improving the uniformity of water temperature.

[0049] like Figure 1As shown, the base plate 530 is a plate with a honeycomb structure, and a reinforcing frame 560 is provided below the plate. The honeycomb structure can prevent dead corners from forming between the tank and the base plate, ensure uniform heating at each location, and eliminate cold spots, such as gaps between the rotating tray or the bottom of the tank. The reinforcing frame can effectively enhance the load-bearing capacity of the rotating tray.

[0050] like Figure 4 As shown, the top of the annular column 540 is provided with a lifting ring 570. The lifting ring is used for lifting the lifting device, which is used to lift the rotating tray into the pot body, making the operation convenient.

[0051] In some embodiments, a cooling coil (not shown in the figure) is coiled around the inner wall of the pot body, and both ends of the cooling coil pass through the wall of the pot body and are connected to an external cooling system. In this embodiment, after the constant temperature sterilization stage, the cooling stage begins. The steam is turned off, the cooling system is turned on, and the water in the pot is cooled through the cooling coil. Cooling water (temperature 15-20℃) is introduced into the cooling coil, and at the same time, sterile compressed air (pressure 0.1-0.15MPa) is introduced through the air pressurization pipe to maintain the pressure inside the pot slightly higher than the external atmospheric pressure to prevent the container from rupturing due to excessive pressure difference (such as glass bottles which are prone to exploding when depressurizing). When the temperature inside the pot drops to 80-90℃, the pressure is gradually released to atmospheric pressure. Then, the next process of atmospheric pressure cooling begins, which can be achieved through a spray cooling tunnel, where the container is sprayed with warm water (60-70℃) and cold water (20-25℃) in sequence, finally cooling down to below 30℃.

[0052] like Figure 1 As shown, in some embodiments, the bottom of the pot body 100 is provided with a drain pipe 130. The drain pipe can discharge impurities and excess water during the sterilization stage. The water level is controlled by the drain pipe to avoid excessive water increasing the energy consumption for heating. When the pressure inside the pot may exceed the safety valve setting value (e.g., 0.15 MPa), the drain pipe can be used in conjunction with the pressure relief pipe to quickly relieve pressure by discharging some water or gas.

[0053] like Figure 1 As shown, in some embodiments, the lid 200 is equipped with a pressure gauge 220, the pressure probe of which extends into the sterilization space inside the pot, and the lid 200 is equipped with a pressure relief pipe 230. In this embodiment, during the pressurization and cooling stage, the pressure inside the pot needs to be monitored by a pressure gauge (usually 0.02~0.05MPa higher than the pressure inside the container) to prevent the glass jar from exploding due to excessive pressure difference between the inside and outside.

[0054] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
