Abstract
Description
Technical Field
[0001] This utility model relates to the field of stock storage, specifically a sterile tank structure for stock storage. Background Technology
[0002] Before packaging, stock needs to be stored in aseptic tanks to prevent spoilage. However, the pressure inside the existing aseptic tanks gradually decreases as the stock cools, making it difficult to discharge the stock and affecting the smoothness of the discharge. At the same time, outside air can easily enter the aseptic tank from the discharge point, causing outside air to mix into the stock during packaging. This makes the packaged stock and the stock in the tank prone to spoilage, affecting the overall quality of the stock. Utility Model Content
[0003] The purpose of this invention is to provide a sterile tank structure for storing broth, which can solve the technical problems of poor material discharge and easy mixing of outside air into existing sterile tanks, which leads to spoilage of the broth. By balancing the internal air pressure of the sterile tank, the smoothness of material discharge is ensured, and sterile gas is replenished in a timely manner to avoid the mixing of outside air during material discharge, thus ensuring the quality of the broth.
[0004] To achieve the above objectives, this utility model employs the following technical solution:
[0005] A sterile tank structure for storing broth includes a tank body, a lid movably connected to the top of the tank body, an air inlet on the lid, a gas storage tank communicating with the air inlet on the lid, a sterile filter and an air pump on the gas storage tank, a piston slidably connected inside the air inlet, an operating rod for controlling the piston to slide up and down on the gas storage tank, and a communicating elastic air bladder on the side wall of the gas storage tank.
[0006] Furthermore, the side wall of the gas storage tank is provided with multiple through-holes, and the elastic airbag surrounds the outside of the multiple through-holes.
[0007] Furthermore, a conduit is provided between the sterile filter and the gas storage tank, and a one-way valve is provided on the conduit.
[0008] Furthermore, a connected drying box is provided below the air inlet, the drying box contains a desiccant, and the top and bottom of the drying box are provided with through holes.
[0009] Furthermore, the operating lever passes through the gas storage tank and is threadedly connected to it, and the bottom of the operating lever is rotatably connected to the top of the piston.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. This utility model provides a cover on the top of the tank, with a through air inlet on the cover. The cover also has a gas storage tank connected to the air inlet. The gas storage tank is equipped with a sterile filter and an air pump. This structure allows the air pump to supply sterile air filtered by the sterile filter into the gas storage tank. This ensures that when the internal air pressure of the tank decreases due to thermal expansion and contraction during the cooling process of the broth, the sterile gas in the gas storage tank can enter the tank through the air inlet to replenish the pressure, thus maintaining the air pressure balance inside and outside the tank. This makes the subsequent discharge of broth from the tank smoother.
[0012] 2. A piston is slidably connected inside the air inlet. The air storage tank is equipped with an operating rod to control the piston's up-and-down movement. An elastic air bladder is connected to the side wall of the air storage tank. This structure allows the piston to slide downwards and close the air inlet during subsequent storage of the broth. Simultaneously, an air pump injects sterile air into the air storage tank, causing the elastic air bladder on the side of the tank to expand, thus storing a certain amount of sterile air at a pressure greater than atmospheric pressure. When the broth is discharged from the tank, the piston is driven upwards by the operating rod to open the air inlet. Under pressure, the sterile air in the air storage tank automatically passes through the air inlet and enters the tank, making the pressure inside the tank greater than the external atmospheric pressure. This further improves the smoothness of the broth discharge and suppresses external air from entering the tank from the discharge position, preventing the introduction of bacteria-containing gases from the outside during broth packaging. This achieves a sterile packaging process for the broth, effectively preventing spoilage of the packaged broth and the broth inside the tank, ensuring the quality of the broth.

[0020] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.
[0021] Reference Figure 1 and Figure 2This utility model describes a sterile container structure for storing broth. The main structure includes a container body 1, which is made entirely of stainless steel to prevent spoilage and leakage of the broth. A lid 2 is movably connected to the top of the container body 1. Specifically, the lid 2 can be detachably connected to the container body 1 using a locking mechanism or similar structure. After the lid 2 is opened, the broth is poured into the container body 1 from the top. A discharge pipe is located near the bottom of the container body 1 for discharging the broth during packaging. The lid 2 has a through air inlet 3, allowing sterile air to enter the container body 1 through the air inlet 3. A gas storage tank 4 is located on the lid 2 and communicates with the air inlet 3. The gas storage tank 4 is connected to the container body 1 through the air inlet 3. The interior of body 1 is interconnected and sealed with a sealing strip to prevent the entry of external air. The gas storage tank 4 is equipped with a sterile filter 5 and an air pump 6. The sterile filter 5 can be any existing filter structure capable of sterilizing air, ensuring that incoming air becomes sterile after being filtered and disinfected by the filter element. The air pump 6 pumps external air, after passing through the sterile filter 5, into the gas storage tank 4. This structure allows for the pumping of sterile air, processed by the sterile filter 5, into the gas storage tank 4 when the internal pressure of the tank 1 decreases due to thermal contraction during broth cooling. The sterile air enters the tank through the air inlet 3. The pressure inside the tank 1 is replenished to ensure the balance of pressure inside and outside the tank 1, which improves the smoothness of the broth discharge during subsequent broth packaging. A piston 7 is slidably connected inside the air inlet 3. The gas storage tank 4 is equipped with an operating rod 8 to control the up-and-down sliding of the piston 7. The operating rod 8 drives the piston 7 to slide up and down inside the air inlet 3, realizing the opening and closing control of the air inlet 3. The side wall of the gas storage tank 4 is equipped with a connected elastic air bladder 9. The elastic air bladder 9 can be made of elastic rubber, which can elastically expand under pressure. In the subsequent broth storage process, the operating rod 8 controls the piston 7 to slide down into the air inlet 3 to close it, using the gas... Pump 6 pumps sterile gas into the gas storage tank 4, causing the elastic air bladder 9 to expand. This stores a certain amount of sterile air in the gas storage tank 4 at a pressure greater than the external atmospheric pressure. When the broth is discharged and packaged in the tank 1, the piston 7 is driven upward by the operating lever 8 to open the air inlet 3. The gas in the gas storage tank 4 can automatically enter the tank 1 under pressure to replenish the broth, making the air pressure in the tank 1 greater than the external atmospheric pressure. This makes the broth discharge faster. At the same time, the pressure can effectively suppress the entry of bacteria-containing gas from the outside into the tank 1 from the discharge position, thereby preventing bacteria-containing gas from mixing into the broth, preventing the broth from spoiling and deteriorating, and effectively ensuring the quality of the broth.
[0022] Preferred, refer to Figure 3 and Figure 4The side wall of the gas storage tank 4 is provided with multiple through notches 10. The elastic airbag 9 surrounds the outside of the multiple notches 10. The notches 10 allow sterile air in the gas storage tank 4 to smoothly enter the elastic airbag 9 on the side, thereby driving the elastic airbag 9 to expand under pressure, making the connection between the elastic airbag 9 and the side wall of the gas storage tank 4 more secure and ensuring the overall sealing.
[0023] Preferably, a conduit 11 is provided between the sterile filter 5 and the gas storage tank 4. The conduit 11 is generally made of plastic or glass and is equipped with a one-way valve 12. With this structure, the air pump 6 pumps sterile air into the gas storage tank 4, making the internal air pressure greater than the external atmospheric pressure. The one-way valve 12 can prevent the sterile gas in the gas storage tank 4 from being discharged in reverse, thus ensuring the air pressure inside the gas storage tank 4. This provides sufficient pressure for the subsequent discharge of broth from the tank 1, improves the suppression effect on external bacteria-containing gases, and effectively prevents the entry of external bacteria-containing gases during discharge.
[0024] Preferred, refer to Figure 5 Below the air inlet 3, a connected drying box 13 is fixed by welding or integral molding. The drying box 13 contains a desiccant, such as calcium oxide or activated carbon. The top and bottom of the drying box 13 are provided with through holes 14. This structure uses the desiccant inside the drying box 13 to dry the sterile gas entering the broth, avoiding the introduction of additional moisture when the gas is replenished, and further ensuring the concentration and quality of the broth.
[0025] Preferably, the operating rod 8 passes through the gas storage tank 4 and is threadedly connected to it. The bottom of the operating rod 8 is rotatably connected to the top of the piston 7 through a bearing. With this structure, when in use, only the operating rod 8 needs to be rotated to drive the piston 7 rotating at the bottom to move up and down under the action of the threaded connection, making the sliding control of the piston 7 faster and more accurate.
[0026] Working Principle: This utility model features a cover 2 on the top of the tank 1, with a through air inlet 3. A gas storage tank 4, connected to the air inlet 3, is also located on the cover 2. The gas storage tank 4 is equipped with a sterile filter 5 and an air pump 6. This structure allows the air pump 6 to supply sterile air filtered by the sterile filter 5 into the gas storage tank 4. This ensures that during the cooling process of the broth, when the internal pressure of the tank 1 decreases due to thermal expansion and contraction, the sterile gas in the gas storage tank 4 can enter the tank 1 through the air inlet 3 to replenish the pressure, maintaining a balance between the internal and external pressures of the tank 1. This facilitates smoother broth discharge from the tank 1. A piston 7 is slidably connected inside the air inlet 3. The gas storage tank 4 has an operating rod 8 that controls the up-and-down movement of the piston 7. An elastic air bladder 9 is connected to the side wall of the gas storage tank 4. This structure... During subsequent storage of the broth, the piston 7 is driven downward by the operating lever 8 to close the air inlet 3. At the same time, sterile air is pumped into the air storage tank 4 by the air pump 6, causing the elastic air bladder 9 on the side of the air storage tank 4 to expand, thereby storing a certain amount of sterile air with a pressure greater than atmospheric pressure. When the broth in the tank 1 is discharged, the piston 7 is driven upward by the operating lever 8 to open the air inlet 3. Under the action of pressure, the sterile air in the air storage tank 4 automatically passes through the air inlet 3 and enters the tank 1, making the pressure inside the tank 1 greater than the external atmospheric pressure. This further improves the smoothness of the broth discharge and suppresses the entry of external air into the tank 1 from the discharge position, preventing the mixing of external bacteria-containing gases during the broth discharge and packaging process. This achieves the sterile packaging process of the broth, effectively preventing the spoilage and deterioration of the packaged broth and the broth in the tank 1, and ensuring the quality of the broth.
