Description

Technical Field

[0001] The invention relates to the technical field of microwave sterilization equipment, in particular to liquid pipeline microwave low-temperature sterilization equipment. Background Art

[0002] In the liquid food processing and pharmaceutical industries, sterilization is a key step to ensure product safety and extend shelf life. Traditional sterilization methods, such as thermal sterilization (including heating and steam sterilization), can effectively kill bacteria, but these methods have obvious limitations. First, traditional methods usually require a long processing time, which not only reduces production efficiency but also may lead to excessive energy consumption. Second, high-temperature processing may destroy the flavor and nutritional content of the product, especially for heat-sensitive liquids, such as certain medicines and functional beverages. This damage is particularly significant.

[0003] In recent years, microwave sterilization technology, as an emerging sterilization method, has attracted widespread attention due to its unique advantages. Microwave sterilization uses microwave electromagnetic fields to cause violent vibration and friction of polar molecules (such as water molecules) in liquids, thereby generating heat at the molecular level, leading to the destruction of bacterial cell structures or the relaxation of intermolecular hydrogen bonds, thereby achieving the purpose of sterilization. Compared with traditional thermal sterilization, microwave sterilization has the following significant advantages: Fast and efficient: Microwave sterilization can be completed within a few minutes, significantly shortening the sterilization time and improving production efficiency.

[0004] Low temperature operation: Microwave sterilization can be carried out at relatively low temperatures, which helps to preserve the flavor and nutrients of the product, especially suitable for heat-sensitive liquids.

[0005] Although microwave sterilization technology has shown great potential in the production process of liquid materials, it still faces some challenges in practical application. In particular, in the secondary sterilization process after the liquid is bottled, the existing microwave sterilization technology has some operational disadvantages. For example, it is usually necessary to place containers containing liquids (such as oral liquids, syrups, health teas, etc.) in a specific container box in turn, and then transport the container box to the bottom of the microwave sterilizer through a belt transmission system for sterilization. This method has the following problems in actual operation: 1. Low efficiency: Since the containers need to be placed in the container box one by one, the entire operation process takes a long time, and after sterilization, the containers in the container box need to be taken out to facilitate subsequent packaging, which affects the overall production efficiency; 2. Complex assembly and disassembly: During the installation and disassembly process of the existing microwave sterilization equipment, the connection between the two sterilization boxes alone requires about 80 bolts, which require the installers to operate one by one, which is time-consuming and labor-intensive.

[0006] Develop a new type of microwave low-temperature sterilization equipment for liquid pipelines to solve the above problems, improve the sterilization efficiency and quality, which has important practical significance and application value. Therefore, we propose a microwave low-temperature sterilization equipment for liquid pipelines. Summary of the Invention

A exhaust hot air fan is installed on the first communication pipe. The auxiliary mechanism also includes a exhaust humid air cylinder installed through the box cover. The bottom end of the exhaust humid air cylinder is communicated with the bottommost layer of the placement rack. The exhaust humid air cylinders of multiple sterilization box bodies are communicated with each other through a second communication pipe. A exhaust humid air fan is installed on the second communication pipe. The exhaust hot air fan and the exhaust humid air fan are fixed on the sterilization box body through brackets.

[0011] Preferably, a temperature sensor and a humidity sensor are arranged inside the sterilization chamber. A first electric control valve is installed on each of the hot air exhaust ducts, and a second electric control valve is installed on each of the moisture exhaust ducts. The valve cores of the first electric control valve and the second electric control valve are both coated with a reflective coating.

[0012] Preferably, absorption layers are arranged on the inner walls of the first connecting pipe and the second connecting pipe for absorbing microwave energy.

[0013] Preferably, a first base is arranged on one side of the sterilization chamber close to the automatic feeding machine. A first microwave suppressor is installed on the first base.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Embodiment 1: See also Figure 1-Figure 10 The present invention provides a technical solution: a liquid pipeline microwave low temperature sterilization device, such as Figure 1 , Figure 4 , Fig.10As shown in the figure, it includes a sterilization box body 1. An observation window 11 is provided on the sterilization box body 1. There are multiple sterilization box bodies 1, and material passing ports 12 are provided on both sides. The multiple sterilization box bodies 1 are docked with each other. The docking part adopts an anti-flow groove design, and adjacent two sterilization box bodies 1 are fixed by a buckle 13. A placement rack 14 is provided in each sterilization box body 1. The placement rack 14 has two layers. One layer is used for wiring, and the other layer is provided with a microwave generator 2. There are multiple microwave generators 2. It also includes: An automatic feeding machine 3, which is used for feeding tubular materials, and a discharge inclined plate 31 is installed at the discharge end; A belt conveyor 4 is arranged through the sterilization box body 1, and both ends are located outside the sterilization box body 1 respectively. Limit plates 41 are arranged on the belt of the belt conveyor 4. There are multiple limit plates 41 and they are evenly distributed. The discharge inclined plate 31 is located directly above the feeding end of the belt conveyor 4; An auxiliary mechanism 5 is installed inside the sterilization box body 1 to improve the product quality by adjusting the temperature and humidity inside the sterilization box body 1.

[0021] It should be noted that there are at least two sterilization box bodies 1. One is used for preheating and the other is used for sterilization. Assuming the sterilization temperature of the product is 90 °C, the temperature inside the sterilization box body 1 for preheating should be between 30 - 40 °C, which can be achieved by changing the power of the microwave generators 2 in different sterilization box bodies 1, avoiding the product container from cracking due to a sharp temperature difference in a short time. The distance between the limit plates 41 is preferably 5 - 15 cm, and corresponding settings are made according to the sterilization of different products, restricting the product within a smaller range to avoid the product from rolling due to the transmission of the belt conveyor 4 and ensuring that the product moves synchronously with the belt conveyor 4.

[0022] High-purity alumina fiber 6 is arranged on the bottom surface of the layer of the placement rack 14 close to the belt conveyor 4. The high-purity alumina fiber 6 is arranged in a "冂" shape and is limited by a mesh cover 61. The mesh cover 61 is made of polypropylene.

[0023] The high-purity alumina fiber 6 does not react with microwaves and has excellent heat insulation performance, avoiding the rapid loss of temperature inside the sterilization box body 1, thereby reducing the power consumption of the microwave generator 2 and lowering the production cost.

[0024] The distance from the side of the high-purity alumina fiber 6 opposite to the belt conveyor 4 to the belt conveyor 4 is 10 - 20 cm.

[0025] The space with a height of 10 - 20 cm can heat the space passed by the product in a shorter time. At the same time, the smaller space is conducive to the uniform distribution of heat, avoiding local overheating in the space, which has a positive effect on the final quality of the product.

[0026] It should be noted that the company can make adjustments based on the actual products. If it is a smaller product such as oral liquid, syrup, etc., a height of 10 cm is appropriate. If it is a larger product such as liquor, beverages, etc., the height should be appropriately increased. It can be adjusted by increasing or decreasing the volume of the high-purity alumina fiber 6.

[0027] The auxiliary mechanism 5 includes a box cover 51 installed on the top of the sterilization box 1, and a heat exhaust air cylinder 52 is installed on the box cover 51. The heat exhaust air cylinder 52 passes through the center position of the placement rack 14, and the bottom end of the heat exhaust air cylinder 52 is connected to the bottom layer of the placement rack 14. The heat exhaust air cylinders 52 of multiple sterilization boxes 1 are interconnected through a first connecting pipe 53, and a heat exhaust fan 54 is installed on the first connecting pipe 53. The auxiliary mechanism 5 also includes a dehumidification air cylinder 55 installed on the box cover 51, and the bottom end of the dehumidification air cylinder 55 is connected to the bottom layer of the placement rack 14. The dehumidification air cylinders 55 of multiple sterilization boxes 1 are interconnected through a second connecting pipe 56, and a dehumidification fan 57 is installed on the second connecting pipe 56. The heat exhaust fan 54 and the dehumidification fan 57 are fixed to the sterilization box 1 through a bracket 58.

[0028] like Figure 7 As shown, a temperature sensor 15 and a humidity sensor 16 are provided in the sterilization box 1, a first electrically controlled valve 521 is installed on the heat exhaust air cylinder 52, and a second electrically controlled valve 551 is installed on the moisture exhaust air cylinder 55. The valve core surfaces of the first electrically controlled valve 521 and the second electrically controlled valve 551 are plated with a reflective coating.

[0029] The temperature sensor 15 and the humidity sensor 16 monitor the temperature and humidity in the sterilization box 1 in real time. When the temperature in the sterilization box 1 is higher than the sterilization temperature required by the product, the first electrically controlled valve 521 and the heat exhaust fan 54 are turned on, and the heat exhaust fan 54 extracts the hot air in the box through the first connecting pipe 53 and the heat exhaust air cylinder 52. The smaller space is also conducive to the rapid drop in the temperature in the sterilization box 1, reducing the loss of the product. When the humidity in the sterilization box 1 is too high, the second electrically controlled valve 551 and the dehumidification fan 57 are turned on, and the dehumidification fan 57 extracts the moisture in the box through the second connecting pipe 56 and the dehumidification air cylinder 55. When the temperature and humidity in the sterilization box 1 reach the ideal value, the first electrically controlled valve 521, the second electrically controlled valve 551, the dehumidification fan 57, and the heat exhaust fan 54 are closed; The reflective coating on the surface of the valve core can effectively prevent microwave energy from leaking from the heat exhaust air cylinder 52 and the moisture exhaust air cylinder 55 when the temperature and humidity of the sterilization box 1 are lower than or equal to the ideal values ​​for sterilization.

[0030] The inner walls of the first connecting tube 53 and the second connecting tube 56 are both provided with an absorption layer for absorbing microwave energy.

[0031] During the process of discharging hot air and moisture in the sterilization chamber 1, due to the opening of the first electric control valve 521 and the second electric control valve 551, a small amount of microwave energy may enter the first connecting pipe 53 and the second connecting pipe 56 through the hot air discharge pipe 52 and the moisture discharge pipe 55, and the absorption layer absorbs this part of the microwave energy.

[0032] As Figure 2 , Figure 3 shown, a first base 7 is provided on one side of the sterilization chamber 1 close to the automatic feeding machine 3. A first microwave suppressor 71 is installed on the first base 7. The first microwave suppressor 71 is in an "n" shape, located between the automatic feeding machine 3 and the sterilization chamber 1 close to the automatic feeding machine 3, and one end is close to the discharge inclined plate 31, and the other end is communicated with the material passing port 12 of the corresponding sterilization chamber 1.

[0033] As Figure 5 shown, a second base 8 is provided on one side of the sterilization chamber 1 far from the automatic feeding machine 3. A second microwave suppressor 81 is installed on the second base 8. The shape of the second microwave suppressor 81 is the same as that of the first microwave suppressor 71, and one end is communicated with the material passing port 12 of the corresponding sterilization chamber 1. A control terminal 82 is provided on the second microwave suppressor 81. The control terminal 82 is electrically connected to the automatic feeding machine 3, the belt conveyor 4, the heat discharge fan 54, and the moisture discharge fan 57.

[0034] The first microwave suppressor 71 and the second microwave suppressor 81 respectively suppress the microwaves emitted from the material passing ports 12 at both ends of the multiple connected sterilization chambers 1 to ensure a safe production environment. At the same time, the second microwave suppressor 81 suppresses the microwaves at the near outlet end of the belt conveyor 4, and can also reduce the temperature of the product when it is finally discharged. If it is collected manually later, it can also be taken safely. The control terminal 82 is a prior art and is responsible for the coordinated cooperation of each component through programming.

[0035] A discharge inclined plate 42 is installed at one end of the belt conveyor 4 close to the control terminal 82. The included angles between the discharge inclined plate 42 and the discharge inclined plate 31 and the ground are both 10 - 15°.

[0036] The inclination angle of 10 - 15° enables the product to roll smoothly from the automatic feeding machine 3 onto the belt conveyor 4, and at the same time will not damage the product due to excessive speed. The same is true for the discharge inclined plate 42 at the discharging end of the belt conveyor 4. It should be noted that the discharging end of the discharge inclined plate 42 can be directly connected to the packaging line to further realize the automatic sterilization and packaging of the product and further improve the production efficiency.

[0037] As Fig. 9As shown, a cooling tower 9 is provided on one side of the sterilization box 1. The cooling tower 9 is connected to the equipment through an inlet pipe 91 and an outlet pipe 92 respectively to form a water circulation cooling system. A hollow sleeve 10 is provided on the outer periphery of the first connecting pipe 53 and the second connecting pipe 56. The outlet pipe 92 of the cooling tower 9 is connected to the hollow sleeve 10.

[0038] The cooling tower 9 can effectively absorb the heat generated by the equipment to avoid malfunctions caused by long-term operation in a high-temperature environment. The absorption layer of the first connecting pipe 53 and the second connecting pipe 56 will heat up after absorbing a certain amount of microwave energy. At the same time, when the heat exhaust fan 54 and the moisture exhaust fan 57 are turned on, a large amount of high-temperature gas will also be discharged. During the water circulation process of the cooling tower 9, the first connecting pipe 53 and the second connecting pipe 56 are cooled synchronously through the hollow sleeve 10, which greatly improves the working environment of the workers.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
