Description

Technical Field

[0001] This utility model relates to the field of sterilization device technology, and more specifically, to an air bath sterilization system and a plant extract sterilization system. Background Technology

[0002] Existing sterilization technologies mainly include high-temperature autoclave (HTSA) sterilization and ultra-high-temperature (UHT) sterilization. HTSA, also known as moist heat sterilization, commonly uses 121°C, 103.4 kPa high-pressure steam for 15-30 minutes. Leveraging the strong penetrating power of high-temperature steam, it destroys microbial proteins and nucleic acids. It is suitable for heat- and moisture-resistant items such as medical devices and culture media, but not for sterilizing beverages or plant extracts. UHT sterilization uses ultra-high temperatures of 135-150°C for only a few seconds to tens of seconds. Through extremely rapid heating and cooling, it kills microorganisms in liquids such as milk and juice, preserving nutrients and flavor to the greatest extent possible. It is commonly used in the food industry. However, both of these methods require temperatures exceeding 100°C. Excessive temperatures can damage food nutrients (e.g., vitamin decomposition) and alter flavor (e.g., protein denaturation producing a burnt taste).

[0003] Therefore, it is particularly necessary to provide a device capable of sterilization at a lower temperature below 100°C. Utility Model Content

[0004] The purpose of this invention is to provide an air bath sterilization system and a plant extract sterilization system, which can sterilize at a relatively low temperature below 100°C and reduce heat waste.

[0023] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0024] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0025] This utility model provides an air bath sterilization system, such as... Figure 1 As shown, it includes: Sterilization tank 100 is used for boiling liquid materials to be sterilized at atmospheric pressure. It includes a container cavity for holding the liquid materials to be sterilized and a steam cavity for providing heat to the container cavity. The steam cavity is provided with a steam inlet and a steam outlet. The steam inlet is connected to a steam source. High-temperature filling machine 200 is used to fill liquid materials from sterilization tank 100 into storage device 500; Insulated room 300, used to store storage device 500 from high temperature filling machine 200; A heating element 400 is located inside the insulation chamber 300 and is used to maintain the temperature inside the insulation chamber 300 at a preset temperature. The inlet of the heating element 400 is connected to the steam outlet, and the heating element 400 is provided with a condensate drain outlet and a pressure relief outlet.

[0026] When using the air bath sterilization system of this application to sterilize liquids, the liquid material to be sterilized is first transferred to the receiving cavity of the sterilization tank 100. The steam in the steam chamber can heat the liquid in the receiving cavity to 100°C. If necessary, the liquid material to be sterilized can be kept warm in the receiving cavity for a period of time for atmospheric pressure boiling sterilization. In some special cases, it can also be heated to a specified temperature below 100°C for sterilization.

[0027] After sterilization in sterilization tank 100, the liquid material can be transported through pipeline to filling machine and filled into storage device 500, where storage device 500 can be a filling bag or bottle, and the specific form of storage device 500 is not limited.

[0028] Next, the storage device 500 is transferred to the insulation chamber 300, and the insulation chamber 300 is heated by the heating tube 400 to maintain the temperature in the insulation chamber 300 at the preset temperature. Under normal circumstances, for liquid beverages, the preset temperature can be 80-90℃. The insulation time in the insulation chamber 300 is greater than 30 minutes for heat preservation and sterilization to enhance the sterilization effect, so that the sterilization effect is comparable to that of ultra-high temperature instantaneous sterilization.

[0029] It should be noted that in the heat preservation chamber 300 of this application, the steam in the heating pipe 400 comes from the high-temperature exhaust gas and wastewater discharged from the sterilization tank 100. The heat preservation chamber 300 can utilize the residual heat in the exhaust gas discharged from the sterilization tank 100 to reduce heat waste. Moreover, no additional energy is required in the heat preservation and sterilization process, and the maximum temperature during the sterilization process does not exceed 100°C. High pressure is also not required, making it safe and energy-saving.

[0030] In an optional embodiment, a transfer vehicle is also included for transferring the storage device 500 from the high-temperature filling machine 200 to the insulation room 300.

[0031] Using transfer vehicles for transportation improves efficiency.

[0032] In an optional embodiment, a tray is also included for holding the storage device 500 from the high-temperature filling machine 200, and the transfer vehicle is used to transfer the tray and the storage device 500 contained in the tray together to the insulated room 300.

[0033] The storage device 500 is placed on a pallet for easy transport by a transfer vehicle. In some embodiments, the transfer vehicle can be a forklift or the like.

[0034] In an optional embodiment, the insulation chamber 300 is provided with a sandwich layer on its bottom surface, top surface and side walls, and the heating pipe 400 is disposed in the sandwich layer; this facilitates uniform heating of the insulation chamber 300 and reduces the temperature difference in the insulation chamber 300.

[0035] In an optional embodiment, the outer surface of the insulated room 300 is provided with an insulation layer, which helps to reduce heat loss.

[0036] In alternative implementations, such as Figure 2 As shown, the insulation room 300 is also provided with partition walls 600 that can divide the insulation room 300 into two or more storage areas. The partition walls 600 are provided with heating chambers for accommodating heating tubes 400. Each heating tube 400 in the heating chamber is equipped with an independent control circuit. Each heating tube 400 in the interlayer is equipped with an independent control circuit.

[0037] Each heating tube segment 400 in the heating chamber corresponds to a dedicated on / off control module, supporting independent start / stop of individual segments of the heating tube 400 in different heating chambers or layers. Selective on / off control of different partition walls 600 can be performed according to heating requirements. Specifically, an inlet valve can be installed at the inlet of each heating tube 400 in the heating chamber or layer, and an outlet valve can be installed at the outlet.

[0038] In some cases, production may fluctuate significantly, such as during peak and off-peak seasons. To meet demand, the area of ​​the insulation room 300 may be larger to accommodate peak season needs. However, during the off-peak season, sales may decrease, leading to reduced production efficiency and a decrease in the storage capacity of the storage devices 500 within the insulation room 300. If the insulation room 300 is insulated as a whole, the amount of high-temperature exhaust gas and wastewater discharged from the sterilization tank 100 will increase. Therefore, by setting up independent start-stop cycles for each segment of the heating pipes 400 in different heating chambers or interlayers, insulation can be selectively applied to one or several storage areas as needed, while other storage areas without storage devices 500 do not require heating, thus reducing the amount of high-temperature exhaust gas and wastewater discharged from the sterilization tank 100.

[0039] In an optional embodiment, the insulation room 300 is provided with a slide rail and pulleys that can drive the partition wall 600 to slide along the slide rail.

[0040] The partition walls are movable, allowing the size of each storage area to be controlled as needed, making the entire air bath sterilization system more flexible in use.

[0041] In some implementations, some partition walls 600 may be equipped with pulleys, and some partition walls 600 may be directly fixed to the ground.

[0042] In an optional embodiment, end plates 700 are provided at both ends of the partition wall 600, and the end plates 700 are perpendicular to both the partition wall 600 and the ground.

[0043] The adjacent partition wall 600 and end plate 700 work together to separate the storage area from other areas of the insulated room 300, reducing heat exchange between the insulated storage area and other uninsulated areas, which is more conducive to the uniformity and stability of the storage area temperature. Figure 3 As shown.

[0044] In an optional embodiment, a high-temperature resistant elastic pad is provided at the end of the end plate 700 away from the partition wall 600 to protect the end plate 700.

[0045] In an optional implementation, there are two or more partition walls 600, which are arranged in parallel to divide the insulation room 300 into three or more side-by-side storage areas.

[0046] This utility model also provides a plant extract sterilization system, including the air bath sterilization system described in any of the foregoing embodiments.

[0047] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
