Technical Field
[0001] This utility model relates to the field of quick-freezing technology, and in particular to a protective isolation device for the safe production of quick-frozen food. Background Technology
[0002] As an important category of frozen food, the cleaning of vegetable raw materials during the production process of frozen dumplings is a crucial step in ensuring food safety and quality. Vegetables are easily contaminated with dirt, stones, and plastic fragments during harvesting, transportation, and storage. If not cleaned thoroughly, this will directly lead to quality problems such as excessive microorganisms and foreign matter contamination in the finished frozen dumplings, seriously threatening consumer health.
[0003] The existing vegetable washing process for quick-frozen dumplings mostly adopts the "open washing tank + manual sorting" model. During the washing process, employees need to sort vegetables by hand, such as removing rotten leaves and trimming roots. When their hands touch the surface of the vegetables, bacteria from their skin can easily be transferred to the raw materials. At the same time, droplets produced by employees talking or coughing can fall directly into the washing tank or onto the surface of the vegetables. Especially in continuous production lines, the droplet contamination spreads along the production line, leading to excessive microbial levels in the washed vegetables. This requires additional disinfection processes and extends the production cycle. Therefore, we propose a protective isolation device for the safe production of quick-frozen food.

Conveying rollers 14: There are two in total, both of which are rotatably connected inside the vegetable washing box 1. The outer surface is driven by the conveying screen 15. They rotate under the drive of the rotating motor 10. Through the transmission cooperation with the conveying screen 15, they drive the conveying screen 15 to run, providing a basic transmission structure for the conveying of vegetables. Conveying screen 15: The transmission sleeve is connected to the outer surface of the two conveying rollers 14 and moves synchronously with the conveying rollers 14. It is used to carry the vegetables to be cleaned and drive the vegetables to move in the vegetable washing box 1 during operation. At the same time, the screen structure allows the washing water to pass through, which facilitates full contact between the vegetables and the water, and can transport the cleaned vegetables to the discharge conveyor 2. Lifting plates 16: Multiple plates are fixedly connected to the outer surface of the conveying screen 15. They move with the conveying screen 15 and can gradually lift the vegetables during operation, preventing them from piling up on the conveying screen 15 and ensuring that the vegetables are evenly distributed on the conveying screen 15. This ensures that each vegetable can fully contact the cleaning roller brush 17 and the cleaning water, thereby improving the uniformity of cleaning. Cleaning roller brush 17: There are two in total, both of which are rotatably connected inside the vegetable washing box 1. One of them is fixedly connected to the output end of the drive motor 7. The two cleaning roller brushes 17 rotate in opposite directions through the meshing of the toothed ring 11. When the roller brush structure rotates, it contacts the surface of the vegetable to scrub away dirt, impurities and other pollutants on the surface of the vegetable and remove dirt. Filter element 18: There are three in total, all of which are slidably installed inside the filter box 9. As the core component for filtering dirty water, when dirty water flows through the filter element 18, the filter element 18 can intercept impurities, sediment and other pollutants in the dirty water and purify the dirty water. The sliding installation method makes it easy to remove the filter element 18 for cleaning or replacement at regular intervals, ensuring the filtration effect.
[0021] Example 1: like Figure 1-4 As shown, during the cleaning process, the water pump 13 is started, and the dirty water in the vegetable washing box 1 is pumped to the filter box 9 through the water pumping pipe 12. Three filter elements 18 are slidably installed inside the filter box 9. When the dirty water flows through the filter elements 18, the impurities, mud and sand in it are filtered and intercepted by the filter elements 18, so that the water is purified. The purified water can be replenished through the water inlet pipe connected to the side of the filter box 9 away from the vegetable washing box 1. At the same time, the water in the filter box 9 can also be discharged through the drain pipe 8 at appropriate times to maintain the cleanliness of the cleaning water and ensure the cleaning effect.
[0022] The protective isolation cover 4 is fixedly connected to the top of the vegetable washing box 1 and the discharge conveyor 2, forming a relatively closed space. This effectively prevents water splashing and external impurities from entering the vegetable washing box 1 during the vegetable washing process, thus preventing secondary contamination of the vegetables and ensuring the safety and hygiene of frozen food production.
[0023] Example 2: like Figure 1As shown, the top cover 5 is tightly installed on the top of the protective isolation cover 4 by bolts, which makes the top cover 5 easy to disassemble and install. After the device has been used for a period of time, when it is necessary to clean the inside, the operator only needs to unscrew the bolts and open the top cover 5 to thoroughly clean the vegetable washing box 1, cleaning roller brush 17, conveying screen 15, filter box 9 and other components, ensuring the normal operation of the device and the cleaning effect.
[0024] Furthermore, when using the device, vegetables are conveyed to the vegetable washing box 1 via the feeding conveyor 3. At this time, the drive motor 7 starts, and its output end drives the corresponding cleaning roller brush 17 to rotate. When one cleaning roller brush 17 rotates, the other cleaning roller brush 17 will also rotate in the opposite direction through the meshing transmission of the toothed ring 11. The two cleaning roller brushes 17 rotating in opposite directions scrub the vegetables to remove dirt, impurities and other contaminants from the surface of the vegetables.
[0025] When the rotating motor 10 starts, its output end drives the conveying roller 14, which is fixedly connected to it, to rotate. Since the conveying screen 15 is driven and sleeved on the outer surface of the two conveying rollers 14, the conveying screen 15 rotates accordingly. At the same time, the multiple lifting plates 16 fixedly connected to the outer surface of the conveying screen 15 can gradually lift the vegetables and convey them forward during operation, so that the vegetables are evenly distributed on the conveying screen 15 for conveying.
[0026] During the cleaning process, the water pump 13 is started, and the dirty water in the vegetable washing box 1 is pumped to the filter box 9 through the water pipe 12. Three filter elements 18 are slidably installed inside the filter box 9. When the dirty water flows through the filter elements 18, the impurities, mud and sand in it are filtered and intercepted by the filter elements 18, so that the water is purified. The purified water can be replenished through the water inlet pipe connected to the side of the filter box 9 away from the vegetable washing box 1. At the same time, the water in the filter box 9 can also be discharged through the drain pipe 8 at appropriate times to maintain the cleanliness of the cleaning water and ensure the cleaning effect.
[0027] The washed vegetables continue to be conveyed forward through the conveyor screen 15 and are finally conveyed to the discharge conveyor 2 to complete the washing and discharge process. The protective isolation cover 4 is fixedly connected to the top of the vegetable washing box 1 and the discharge conveyor 2. The top cover 5 is installed on the top of the protective isolation cover 4 with bolts, forming a relatively closed space. This effectively prevents the washing water from splashing and external impurities from entering the vegetable washing box 1 during the vegetable washing process, thus preventing secondary pollution of the vegetables and ensuring the safety and hygiene of the frozen food production.
[0028] The control panel 6 is fixedly installed on the side of the vegetable washing tank 1 near the drain pipe 8. The operator can control and adjust the start and stop of the drive motor 7, the rotating motor 10, the water pump 13 and other equipment, as well as the operating parameters, through the control panel 6 to realize the automated operation and monitoring of the entire device.
[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
