Technical Field

[0001] The present invention relates to the technical field of fresh wet rice noodle processing, and particularly to a cold sterilization device for fresh wet rice noodles. Background Art

[0002] Fresh wet rice noodles are made from rice and processed through production processes such as grinding, gelatinization and forming, and cooling, but are not dried rice noodles. Currently, the demand for fresh wet rice noodles is increasing, and most are short-term preservation products with a 48-hour shelf life requirement, mainly relying on low-temperature distribution; due to the production environment or control during the production process not meeting the expected requirements, the actual shelf life of the product is shorter, especially significant in summer. In addition, the current product packaging mainly uses manual measurement, resulting in serious cross-contamination, and the existing rice noodle production environment and equipment seriously lag behind the standards of other food industries; with consumers' increasing requirements for food safety and the continuous strengthening of market supervision, the safe circulation of traditional processed bulk foods has always been an issue to be solved. For this reason, we propose a cold sterilization device for fresh wet rice noodles and its usage method. Summary of the Invention

Clear water is injected into the water purifier through the water inlet, and the water purifier can purify and filter the water flow, thereby reducing the pollution of impurities in the water and ensuring the product quality; the purified and filtered water enters the aeration and sterilization assembly after passing through the electrolyzed water generator.

[0020] The following further describes in detail the implementation manners of the embodiments of the present invention in conjunction with the accompanying drawings and embodiments.

[0021] Please refer to Figures 1 to 3 , a cold sterilization device for fresh wet rice noodles in this embodiment includes a water-cooling tank 1, an ultra-clean working chamber 2 and an aeration sterilization component 7. An ultra-clean working chamber 2 is fixed on one side of the water-cooling tank 1, and a water purifier 3 is installed outside the water-cooling tank 1. A water inlet 4 is arranged on the upper side of the water purifier 3, and an electrolyzed water generator 5 is connected to one side of the water purifier 3 through a pipeline. Ozone absorbers 6 are connected to the outer sides of both the water-cooling tank 1 and the ultra-clean working chamber 2 through pipelines; There are three groups of micro-nano bubble generators 701, connecting pipes 702 and aeration pipes 703, and the micro-nano bubble generators 701 are connected to the electrolyzed water generators 5 through pipelines; The specific operation is as follows. Clear water can be injected into the interior of the water purifier 3 through the water inlet 4. The water purifier 3 facilitates the purification and filtration of the water flow. The purification treatment of the water can reduce the impurity pollution of the water to the product and ensure the product quality. The water after purification and filtration enters the aeration sterilization component 7 after passing through the electrolyzed water generator 5. Combining electrolyzed water can compound another sterilization function. The hydrogen generated by the electrolyzed water can increase the freshness preservation effect of the product, so that the fresh wet rice noodles during the cooling process can continue to be cooled by the sterile water inside the water cooling tank 1. The water cooling conveyor belt 901 inside the water cooling tank 1 is of a hollow and water-permeable structure, which is convenient for cooling and feeding the fresh wet rice noodles. The movable transparent covers 902 on both sides of the water cooling conveyor belt 901 can block the gaps between the water cooling conveyor belt 901 and the inner wall of the water cooling tank 1 to prevent the fresh wet rice noodle materials from falling from both sides.

[0022] Please refer to Figure 3 , one end outside the water cooling tank 1 is equipped with an aeration sterilization component 7, and the aeration sterilization component 7 includes a micro-nano bubble generator 701, a connecting pipe 702, an aeration pipe 703, an aeration port 704, an ozone feeding pipe 705 and an ozone generator 706. The micro-nano bubble generator 701 is equipped with a connecting pipe 702 on the side close to the water cooling tank 1, and the other side of the connecting pipe 702 is connected with an aeration pipe 703. The aeration pipe 703 is located below the interior of the water cooling tank 1, and an aeration port 704 is arranged on the outer side of the aeration pipe 703. The upper part of the connecting pipe 702 is connected with an ozone generator 706 through an ozone feeding pipe 705. The aeration sterilization component 7 also includes an ozone access pipe 707. The upper side of the ozone generator 706 is connected with an ozone access pipe 707, and the end of the ozone access pipe 707 is directly communicated with the ultra-clean working room 2; The specific operation is as follows. The ozone generator 706 can generate ozone and send it into the interior of the connecting pipe 702 through the ozone feeding pipe 705. Subsequently, the micro-nano bubble generator 701 facilitates the dispersion treatment of the ozone. Through the aeration of the aeration pipe 703 and the aeration port 704, the dispersion of ozone in the water is increased, so that the ozone is fully dispersed in the water. While increasing the dispersion, it quickly contacts the surface of the material, which will greatly increase the contact surface between the self-oxygen and the rice noodle products and achieve the sterilization effect. At the same time, the time for the ozone-formed bubbles to exist in the water will also be extended. After reducing the bubble diameter, the mass transfer efficiency is increased by more than twice, further enhancing the sterilization effect. Compared with the air-water mixer, this design structure has better dispersion and shorter required time, improving the effective utilization rate of ozone. Therefore, ozone sterilization is used during the cooling process to inactivate the microorganisms contaminated on the surface of the rice noodles in the environment or during the previous cooling process. In addition, the remaining ozone generated by the ozone generator 706 can also be sent into the interior of the ultra-clean working room 2 through the ozone access pipe 707, so that the ultra-clean working room 2 is sterilized by the remaining ozone and forms a positive pressure environment to achieve the purpose of a sterile space environment, enabling the rice noodles after surface sterilization treatment to be packaged in an approximately sterile environment.

[0023] Please refer to Figures 4 to 6 , a circulation filtration component 8 is directly arranged between the water cooling tank 1 and the water purifier 3, and the circulation filtration component 8 includes a filtration tank 801, a reflux pipe 802 and a filter screen 803. The front and rear sides of the filtration tank 801 are respectively communicated with the water cooling tank 1 and the water purifier 3 through two reflux pipes 802, and a filter screen 803 is arranged inside the filtration tank 801; The circulation filtration component 8 further includes a blanking chute 804, a sewage collection tank 805 and a sewage discharge pipe 806. A blanking chute 804 is arranged on the lower side of the filtration tank 801, and the blanking chute 804 is located below the filter screen 803, and the filter screen 803 is of an inclined structure. A sewage collection tank 805 is installed at the bottom of the filtration tank 801, and a sewage discharge pipe 806 is connected to the outer side of the sewage collection tank 805; The specific operation is as follows. The water flow after being used for internal cooling in the water cooling tank 1 can enter the water purifier 3 through the filtration tank 801 and the reflux pipe 802 for reuse. The two groups of inclined filter screens 803 inside the filtration tank 801 can double-filter impurities, and then the preliminarily filtered water flow can be sent into the water purifier 3 through the reflux pipe 802 for subsequent circulation use. The precipitated impurities settle to the blanking chute 804 through the inclined surface of the filter screen 803 and finally enter the sewage collection tank 805. The sewage discharge pipe 806 facilitates the discharge of impurities inside the sewage collection tank 805.

[0024] Please refer to Figure 1 and Figure 6 , a feeding component 9 is installed above the inside of the water cooling tank 1, and the feeding component 9 includes a water-cooled feeding belt 901 and a movable transparent cover 902. The water-cooled feeding belt 901 is a movable hollow and water-permeable structure, and movable transparent covers 902 are arranged on both the left and right sides of the water-cooled feeding belt 901, and the movable transparent covers 902 are connected to the inner wall of the water cooling tank 1; The feeding component 9 further includes a feeding hopper 903, a feeding pipe 904 and a feeder 905. A feeding hopper 903 is arranged on the side of the water-cooled feeding belt 901 close to the ultra-clean working chamber 2, and the feeding hopper 903 is fixedly connected to the inner wall of the water cooling tank 1. A feeding pipe 904 is connected below the feeding hopper 903, and a feeder 905 is installed below the feeding pipe 904; An operating table 10 is fixed inside the ultra-clean working chamber 2, and a secondary feeding belt 11 is arranged on the side of the operating table 10 close to the feeder 905, and a water drainage and collection tank 12 is arranged below the secondary feeding belt 11; Another ultra-clean workbench 13 is fixed on the other side of the operating table 10, and a packaging machine 14 is installed above the operating table 10. An ultraviolet lamp 15 is installed on the inner wall of the ultra-clean working chamber 2 close to the ultra-clean workbench 13; The specific operation is as follows. The fresh and wet rice noodles after being water-cooled by the water-cooled feeding belt 901 can enter the inside of the feeding hopper 903 and pass through the feeding pipe 904 at the bottom of the feeding hopper 903 into the feeder 905. The feeder 905 facilitates the feeding of the fresh and wet rice noodles onto the secondary feeding belt 11 inside the ultra-clean working chamber 2. The secondary feeding belt 11 is a water-permeable structure for draining water, enabling the drain water collection tank 12 below to collect the drained water and return it to the inside of the water-cooling tank 1 through a one-way pipe. The secondary feeding belt 11 facilitates the feeding of the fresh and wet rice noodles to the position of the packaging machine 14 for subsequent packaging. After removing the outer packaging of the packaging bag of the fresh and wet rice noodles, it is placed into the ultra-clean working chamber 2 through the ultra-clean workbench 13, and at the same time, it is treated with an ultraviolet lamp 15. There is ozone gas passing through the ultra-clean working chamber 2, and an ozone absorber 6 is designed near the packaging machine 14 to strengthen the control of the sterile environment of the operation tabletop.

[0025] Working principle: The present invention is not only applicable to fresh and wet rice noodle products but also to other short-shelf-life food products such as "semi-dry rice noodles" and "rice cake products". When in use, first, clean water is injected into the inside of the water purifier 3 through the water inlet 4. The water purifier 3 purifies and filters the clean water, reducing the pollution of the product by impurities in the water to ensure the product quality. Then, the purified and filtered water enters the aeration sterilization component 7 after passing through the electrolyzed water generator 5, combining electrolyzed water with another sterilization function. The hydrogen generated by the electrolyzed water can enhance the freshness preservation effect of the product, enabling the fresh and wet rice noodle products during the cooling process to continue to be cooled by the sterile water inside the water-cooling tank 1. During this process, the ozone generated by the ozone generator 706 is sent to the inside of the connecting pipe 702 through the ozone feeding pipe 705. The micro-nano bubble generator 701 disperses the incoming ozone, and aeration is carried out through the aeration pipe 703 and the aeration port 704, thereby increasing the dispersion of ozone in the water, enabling ozone to be fully dispersed in the water. While increasing the dispersion, ozone quickly contacts the surface of the material, greatly increasing the contact surface between ozone and the rice noodle products, achieving the sterilization effect. At the same time, the time for the ozone-formed bubbles to exist in the water will also be extended. After reducing the bubble diameter, the mass transfer efficiency is increased by more than twice, further enhancing the sterilization effect. Thus, ozone sterilization is used during the cooling process to inactivate the microorganisms contaminated on the surface of the rice noodles in the environment or during the previous cooling process. During use, the water-cooled feeding belt 901 inside the water-cooling tank 1 is a hollow and water-permeable structure, which can cool and feed the fresh wet rice noodles. At this time, the movable transparent covers 902 on both sides of the water-cooled feeding belt 901 can block the gaps between the water-cooled feeding belt 901 and the inner wall of the water-cooling tank 1 to prevent the fresh wet rice noodle materials from falling from both sides. During this process, the water flow used for cooling inside the water-cooling tank 1 can enter the water purifier 3 through the filter box 801 and the return pipe 802 for reuse. The two groups of inclined filter meshes 803 inside the filter box 801 can filter impurities twice, and then the preliminarily filtered water flow can be sent into the water purifier 3 through the return pipe 802 for subsequent recycling. The precipitated impurities settle to the blanking tank 804 through the inclined surface of the filter mesh 803 and finally enter the inside of the sewage collection tank 805. Finally, the impurities inside the sewage collection tank 805 can be discharged through the sewage discharge pipe 806; Then, the fresh wet rice noodles cooled by the water-cooled feeding belt 901 can enter the inside of the blanking hopper 903 and pass through the blanking pipe 904 at the bottom of the blanking hopper 903 into the feeder 905. Through the feeder 905, it is convenient to feed the fresh wet rice noodles onto the secondary feeding belt 11 inside the ultra-clean working chamber 2. The secondary feeding belt 11 is a water-permeable structure for draining water, so that the draining collection tank 12 below collects the drained water and returns it to the inside of the water-cooling tank 1 through a one-way pipe. The secondary feeding belt 11 feeds the fresh wet rice noodles to the packaging machine 14 for subsequent packaging. Before packaging, after removing the outer packaging of the fresh wet rice noodle packaging bag, it is placed into the ultra-clean working chamber 2 through the ultra-clean workbench 13, and at the same time, it is treated with an ultraviolet lamp 15. In addition, ozone gas passes through the ultra-clean working chamber 2, and the ozone remaining gas generated by the ozone generator 706 can also be sent into the ultra-clean working chamber 2 through the ozone access pipe 707, so that the ultra-clean working chamber 2 is sterilized by the ozone remaining gas and forms a positive pressure environment to achieve the purpose of a sterile space environment, so that the rice noodles after surface sterilization treatment are packaged in an approximately sterile environment. At the same time, an ozone absorber 6 is designed near the packaging machine 14 to strengthen the control of the sterile environment of the operation table. In this way, the use process of the whole fresh wet rice noodle cold sterilization device and its use method is completed.
