[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0024] This utility model is a whole vegetable washing and purification processing device based on water hydroxyl technology. It is centrally controlled by an electrical control cabinet 1, which connects a six-station sorting device 2, a whole vegetable washing machine 3, a food purification industrial machine 4, and a whole vegetable drying machine 5 in series according to the production process. This achieves continuous and automated processing of whole vegetables from sorting to drying, completely avoiding the problems of low efficiency and secondary pollution caused by manual, decentralized operation. The specific working principle is broken down by process as follows: I. Overall Control Logic: The Core Scheduling Function of Electrical Control Cabinet 1 The electrical control cabinet 1 serves as the "control center" of the entire device, and is electrically connected to the six-station sorting equipment 2, the whole vegetable washing machine 3, the food purification industrial machine 4, and the whole vegetable drying machine 5. It has three core functions: Start-stop synchronization: It can uniformly control the start and stop of the entire processing line, ensuring that each piece of equipment moves in sequence according to the process flow, and avoiding material accumulation or process disconnection caused by the operation of a single piece of equipment alone; Emergency Interruption: Equipped with an emergency stop function, when any equipment malfunctions (such as conveyor belt jamming, abnormal water tank level) or when abnormal material is discovered manually, the entire production line will stop immediately after the emergency stop is triggered to ensure equipment safety and material quality. Status monitoring: It can receive operating signals from various devices in real time (such as motor speed, water tank level, and fan pressure). If any abnormality occurs (such as low level in the circulating water tank or excessive temperature in the purification system), it will provide timely feedback and prompts to facilitate troubleshooting by operators.

[0025] II. Process 1: Six-station sorting equipment 2 (material initial screening and classification conveying) The six-station sorting equipment 2 is the "first checkpoint" in the processing flow. Its core function is to manually screen qualified whole vegetables and separate waste. Its double-layer conveyor belt structure realizes the diversion of "materials and waste". The specific process is as follows: Material loading and placement: Operators place whole vegetables (such as cabbage, lettuce, broccoli, etc.) to be processed on the detachable inclined shelf 203. The detachable structure facilitates subsequent cleaning and maintenance and meets the hygiene requirements of food processing. Multi-station synchronous sorting: Stepping platforms 206 are set on both sides of the equipment, where operators stand to manually sort the whole vegetables, removing unqualified parts such as rotten, yellow leaves, and impurities. For whole vegetables that need simple trimming (such as cutting off the root), preliminary processing can be completed on the detachable cutting board 204. Bidirectional conveying and diversion: After sorting, qualified whole vegetables are placed on the upper conveyor belt 201. The conveyor belt runs in the direction of the process flow (the direction of connection with the subsequent washing machine) to accurately transport the qualified materials to the feed port of the whole vegetable washing machine 3. The rotten vegetable leaves, impurities, and other waste that are picked out fall directly into the lower conveyor belt 202 through the waste chute 205. The lower conveyor belt 202 runs in the opposite direction to the upper conveyor belt, which can reverse the flow of waste to the waste collection container at the end of the equipment, thus avoiding secondary pollution caused by the mixing of waste with qualified materials.

[0026] Step 2: Whole Vegetable Washing Machine 3 (Double Pre-washing with Bubbling and Spraying) The core of the whole vegetable washing machine 3 is to achieve the initial removal of mud, sand, and dust from the surface of whole vegetables through "bubbling agitation + spray rinsing", while using a circulating water tank to achieve water resource reuse. The specific working logic is as follows: Material receiving and conveying: The washing conveyor belt 301 of the washing machine is driven by an RV motor (high torque, low noise, suitable for food processing scenarios) and a reducer. Its feeding end is precisely connected to the discharging end of the upper conveyor belt 201 of the six-station sorting equipment 2. Qualified whole vegetables enter the washing tank along with the washing conveyor belt 301. Bubble agitation to remove impurities: The stainless steel bubble blower 302 runs continuously, injecting high-pressure airflow evenly into the water through the aeration pipe at the bottom of the cleaning tank, forming a large number of fine bubbles. As the bubbles rise, they cause the water flow in the cleaning tank to be violently agitated, separating the mud, sand, and dust on the surface of the vegetables from the vegetable leaves. At the same time, the impact of the bubbles can prevent the vegetables from sticking together, ensuring that each vegetable can be in full contact with the water. Secondary spray rinsing: The whole vegetables, which move to the middle of the cleaning tank with the cleaning conveyor belt 301, will enter the coverage area of ​​the spray cleaning component 304. The circulating water tank A303 pressurizes the collected cleaning water through the water pump 305 and delivers it to the spray pipe. The high-pressure spray water flow is then formed through the nozzles on the spray pipe to rinse the fine impurities (such as attached mud and sand particles) remaining on the surface of the whole vegetables a second time, thereby improving the cleaning cleanliness. A removable splash guard 306 is provided above the spray assembly to prevent water splashing during the spraying process from polluting the surrounding environment of the equipment, and to avoid water waste. One end of the cleaning conveyor belt 301 can be lifted by the lifting frame 307 and the take-up reel 308: the take-up reel 308 has a self-locking structure. Rotating the take-up reel 308 can pull the spray cleaning assembly 304 through the lifting chain (bypassing the pulley on the lifting frame) to rotate and lift the front end of the cleaning conveyor belt 301 around the rear end, so that the bottom of the cleaning conveyor belt 301 is exposed, which is convenient for subsequent cleaning without dead corners; Water recycling: The water in the cleaning tank will naturally flow into the circulating water tank A303. The water tank is equipped with three control points: low level, replenishment level, and high level. When the water level is lower than the low level, the sanitary pneumatic butterfly valve at the replenishment port will automatically open to replenish water. When the water level reaches the high level, the valve will close, which ensures sufficient cleaning water and avoids overflow waste. At the same time, recycling reduces the consumption of fresh water.

[0027] IV. Process 3: Food purification industrial machine 4 (deep purification: secondary cleaning + sterilization and removal of pesticide residues) The food purification industrial machine 4 is a core component in ensuring the safety and quality of whole vegetables. It achieves pesticide residue degradation and microbial elimination through "secondary cleaning + sterilization and disinfection," while temperature control ensures stable purification results. The specific working principle is as follows: Material connection and conveying: The feed end of the purification conveyor belt 401 of the purifier is connected to the discharge end of the cleaning conveyor belt 301 of the whole vegetable washing machine 3. The whole vegetables that have been initially cleaned enter the purifier along the purification conveyor belt 401 and undergo deep processing during the slow movement. The core function of the purification system: The built-in purification system (water catalyst core technology) releases bactericidal / degradation factors, which combine with the water or air around the purification conveyor belt 401 to facilitate a secondary cleaning of the whole vegetable surface, rinsing away any tiny impurities not removed in the initial cleaning; on the other hand, the bactericidal factors can kill harmful microorganisms such as E. coli and Salmonella on the surface of the whole vegetable, while degrading residual pesticides (such as organophosphates and pyrethroids), thus meeting food safety standards; Temperature and water circulation control: The purifier is equipped with a circulating water tank B402, whose liquid level control logic is the same as that of the circulating water tank A303 (automatic water replenishment through three liquid level control points and a sanitary pneumatic butterfly valve) to ensure sufficient purified water during the purification process. The temperature control unit 403 can monitor the water temperature in the circulating water tank B402 in real time. If the purification process requires a specific temperature (such as low temperature environment to inhibit the growth of microorganisms, or specific temperature to enhance the activity of purification factors), the temperature control unit 403 will call the refrigeration system to adjust the water temperature through the signal interface linked with the factory refrigeration system. When the water temperature is higher than the set value, the refrigeration system will start to cool down; when the water temperature is lower than the set value, the refrigeration system will stop to ensure stable purification effect. Material output: The purified whole vegetables are moved to the discharge end by the purification conveyor belt 401 and accurately conveyed to the drying conveyor belt 501 of the whole vegetable dryer 5.

[0028] Step 4: Whole vegetable air dryer 5 (surface dehydration: avoids secondary contamination + facilitates subsequent processing) The core function of the whole vegetable dryer 5 is to quickly remove moisture from the surface of whole vegetables, preventing residual moisture from causing microbial growth (secondary contamination), while also facilitating subsequent packaging, storage, or further processing. The specific working principle is as follows: Material receiving: The feeding end of the drying conveyor belt 501 of the air dryer is connected to the discharge end of the purification conveyor belt 401 of the food purification industrial machine 4. The purified whole vegetables enter the drying area along the drying conveyor belt 501. High-pressure air drying with air knife 502: Multiple air knives 502 are evenly arranged on the top of the air drying conveyor belt 501. The air knife 502 is connected to the blower 503 through pipes. The high-pressure airflow generated by the blower 503 is formed into a flat, high-speed airflow jet through the air knife 502 and blown vertically or obliquely onto the surface of the whole vegetable. The high-speed airflow can quickly peel off the attached water on the surface of the whole vegetable (such as water droplets in the gaps of vegetable leaves and water film on the surface of vegetable stems). The even arrangement of the air knife 502 ensures that all parts of the whole vegetable can be covered by airflow, avoiding local moisture residue. Output after air drying: The dried vegetables are moved to the discharge end by the air drying conveyor belt 501, and can then enter the subsequent processes (such as packaging, cutting, refrigeration, etc.), and the entire processing flow is completed.

[0029] VI. Summary of the linkage logic of each process Material flow linkage: The whole vegetable is connected sequentially by a conveyor belt, from the six-station sorting equipment 2 (primary screening) → whole vegetable washing machine 3 (primary washing) → food purification industrial machine 4 (deep purification) → whole vegetable air dryer 5 (air drying). There is no manual handling throughout the process, which avoids secondary pollution caused by the material coming into contact with the outside world. Equipment operation linkage: The electrical control cabinet 1 uniformly schedules the start and stop rhythm of each piece of equipment. For example, the speed of the upper conveyor belt 201 of the six-station sorting equipment 2 is matched with the speed of the cleaning conveyor belt 301 of the cleaning machine to ensure that the material enters the cleaning tank evenly, without accumulation or separation; the conveying speed of the purifier is synchronized with the conveying speed of the air dryer to avoid the purified material from staying for a long time before air drying. Resource and safety linkage: The liquid level control of the circulating water tank A303 / B402 and the temperature control of the food purification industrial machine 4 are linked with the electrical control cabinet 1. In case of abnormality, an alarm is triggered in time or a protection mechanism is activated (such as suspending the cleaning / purification process when the liquid level is low), which not only ensures the processing effect but also avoids equipment damage.

[0030] In summary, this device achieves automation, continuity, and safety in the whole-vegetable cleaning and processing through "refined processing by process steps + full-process linkage control," effectively solving the pain points of traditional manual processing. Example

[0031] This embodiment uses "washing and processing whole fresh lettuce" as an application scenario to explain in detail the specific operating parameters, operation process and actual application effect of the whole vegetable washing and processing device, and to verify the practicality and efficiency of the device in the vegetable processing industry.

[0032] Preparations before implementation (a) Equipment parameter settings By pre-setting the operating parameters of each piece of equipment in electrical control cabinet 1, the process flow is ensured to be matched. The specific parameters are shown in the table below: Six-station sorting equipment Upper conveyor belt speed 0.4-3 m / min Six-station sorting equipment Lower conveyor belt speed 1-3m / min Whole vegetable washing machine Cleaning conveyor belt speed 0.4-3 m / min Whole vegetable washing machine Stainless steel blower air pressure 0.01-0.06MPa Whole vegetable washing machine Spray pump pressure 0.002MPa Food purification industrial machine Purification conveyor belt speed 0.38-1.7 m / min Food purification industrial machine Temperature of circulating water tank B 4-6℃ Whole vegetable air dryer Air drying conveyor belt speed 0.5-2 m / min Whole vegetable air dryer Fan air pressure 0.002-0.006MPa (II) Material and Auxiliary Preparation Materials: Select fresh lettuce, ensuring the leaves are not severely rotten (a small amount of yellow leaves can be removed by picking), and meet the size and quality requirements for whole vegetable processing; Auxiliary materials: Inject clean water that meets food processing standards into circulating water tanks A303 and B402, monitor the liquid level through electrical control cabinet 1 to ensure that the water level reaches the "water replenishment level"; check the purification system of food purification industrial machine 4 to ensure that the water hydroxyl generator (purification core component) is in normal standby state and that the signal linkage with the factory refrigeration system is normal.

[0033] II. Specific Implementation Process (a) Process 1: Six-station sorting There are 6 operators, who stand on the foot platforms 206 on both sides of the six-station sorting equipment 2, and each person is responsible for one sorting station. Turn on the "Start Picking Equipment Individually" button on the electrical control cabinet 1, and the upper conveyor belt 201 and the lower conveyor belt 202 will start running; The lettuce to be processed is placed on the inclined shelf 203 by the operator. The operator removes yellow leaves, rotten leaves, and mixed weeds and stones from the lettuce. For lettuce with excessively long roots (root length exceeding 3cm), the excess roots are quickly cut off on the detachable cutting board 204. The removed waste (yellow leaves, weeds, and cut roots) falls into the lower conveyor belt 202 through the waste chute 205, and is then transported in reverse by the lower conveyor belt 202 to the waste collection bin at the end of the equipment. After sorting, qualified lettuce is placed on the upper conveyor belt 201 and falls precisely into the washing conveyor belt 301 of the whole lettuce washing machine 3, completing the initial screening process.

[0034] Step 2: Wash the whole vegetable The whole vegetable washing machine 3 is started by the electrical control cabinet 1, and the washing conveyor belt 301, stainless steel bubbling blower 302 and spray water pump are running simultaneously. Qualified lettuce enters the washing tank via the washing conveyor belt 301. Inside the tank, clean water generates dense bubbles under the action of a blower. As the bubbles rise, they disturb the water flow, washing away the mud and dust on the surface of the lettuce. The lettuce rolls slightly in the water, ensuring that impurities in the gaps between the leaves are removed. When the lettuce moves to the middle of the washing tank with the conveyor belt, the nozzles of the spray washing component 304 above spray high-pressure water to rinse the fine mud and sand remaining on the surface of the lettuce a second time. During the spraying process, the splash baffle 306 effectively blocks water splashes and prevents the surrounding environment from becoming damp. During the cleaning process, the circulating water tank A303 collects the overflow water in the cleaning tank through the overflow channel on one side. When the electrical control cabinet 1 detects that the water level in the tank is lower than the "low level", the sanitary pneumatic butterfly valve at the water inlet will automatically open, replenish clean water to the "water replenishment level" and then close, so as to realize the recycling of water resources. The washed lettuce is fed into the purification conveyor belt 401 of the food purification industrial machine 4 via the discharge end of the washing conveyor belt 301.

[0035] (III) Process 3: Food purification When the electrical control cabinet 1 starts the food purification industrial machine 4, the purification conveyor belt 401, the purification system (water hydroxyl generator), and the temperature control unit 403 operate synchronously. After washing, the lettuce enters the purification machine via the purification conveyor belt 401. The purification system releases hydrohydroxyl groups, which combine with the clean water in the circulating water tank B402 to form hydrohydroxyl water. The water-based hydroxyl group performs a second wash on the surface of the lettuce, removing any remaining tiny impurities; at the same time, the water-based hydroxyl group... It destroys the molecular structure of pesticides on the surface of lettuce (such as degrading organophosphate pesticides) and kills harmful microorganisms such as E. coli and Salmonella (sterilization rate ≥99%). The temperature control unit 403 monitors the water temperature of the circulating water tank B402 in real time. Water from the purifier flows into the circulating water tank B402. The water in the tank is pumped away and enters the cooling pipe heat exchanger. The pipes inside the heat exchanger use propylene glycol to achieve low temperature. When the water passes through the heat exchanger, it is rapidly cooled. The cooled water enters the spray pipe of the purifier and enters the purifier, achieving closed-loop cooling. During the purification process, the liquid level control logic of circulating water tank B402 is consistent with that of circulating water tank A303 to ensure sufficient purified water. The purified lettuce is conveyed to the drying conveyor belt 501 of the whole lettuce dryer 5 via the discharge end of the purification conveyor belt 401.

[0036] (iv) Step 4: Air-drying the whole fruit When the electrical control cabinet 1 starts the whole vegetable air dryer 5, the air drying conveyor belt 501 and the fan 503 run synchronously. After purification, the lettuce enters the drying area via the air-drying conveyor belt 501, where 16 air knives 502 (evenly distributed) at the top of the conveyor belt spray high-speed airflow. Airflow blows onto the surface of the lettuce, quickly stripping away the water adhering to the leaves. The lettuce is slowly turned over during the conveyor belt process (with a slight bumpy design) to ensure that water droplets on the back of the leaves and in the crevices are completely blown away. After being air-dried, the lettuce has no obvious water stains on its surface (moisture content ≤10%) and falls into the collection basket at the discharge end of the air-drying conveyor belt 501, completing the entire processing procedure.
