The Onion Vegetable Weight Grading Machine is an automated device specifically developed for onion processing. It accurately grades and sorts onions based on weight while also offering high-speed operation. Whether it’s post-harvest sorting of fresh onions, quality grading of export onions, or pre-processing raw materials before further processing, this device precisely meets the needs, effectively addressing the pain points of manual grading, including low efficiency, large errors, and high costs, and establishing an efficient and stable grading production line for onion processing companies.
This onion weight grading machine utilizes an integrated "conveying - weighing - identification - 排序" workflow. Its core principles are as follows:
First, 洋葱, after pre-cleaning and impurity removal, enter the machine at a constant speed via an inclined feed conveyor belt made of food-grade silicone to prevent damage to the onion skin.
The onions are then conveyed individually to a high-precision weighing module equipped with imported load cells, capable of collecting individual onion weights within 0.1 seconds and transmitting the data in real time to a central control system.
The control system quickly compares the weight data against pre-set grading standards (例如。, 200-300G, 300-400G, and over 400g) to determine the onion's grade.
最后, the system issues commands to the corresponding grade's sorting actuators, which use pneumatic pushers or paddles to smoothly push the onions to different discharge channels, completing the entire grading process. This process requires no human intervention and can operate continuously 24 hours a day.
Improved Grading Accuracy: A high-precision weighing system and automated sorting mechanism eliminate misclassifications caused by traditional manual labor or size determination, thereby improving onion grading consistency.
Significantly Reduced Labor Costs and Operational Difficulty: Automated operation significantly reduces labor input, while accelerating production and reducing errors.
Optimized Onion Utilization and Reduced Waste: Precise grading prevents quality loss or substandard packaging due to improper grading, thereby increasing output value.
Adaptable to Multiple Export or Packaging Specifications: This equipment can quickly switch grading standards to meet onion export or retail specifications, providing high flexibility.
High-Precision Weighing System: Equipped with imported weighing sensors, the system boasts a weighing accuracy of ±1g, compared to the ±3g accuracy of standard equipment. This allows for more precise onion grading, avoiding grading errors caused by insufficient precision and ensuring consistent weight across all grades.
High-Speed Design: The system utilizes a dual-conveyor parallel conveyor system and an optimized sorting actuator, capable of processing 80-120 onions per minute and 4,800-7,200 onions per hour. This significantly surpasses the traditional manual sorting efficiency of 300-500 onions per hour, significantly increasing the overall production capacity of the onion grading line.
Onion-Specific Protection: Considering the thin and fragile skin of onions, the system's feed inlet, conveyor belts, and sorting channels all feature a curved transition design. All components that come into contact with the onions are made of food-grade soft silicone with a low friction coefficient, effectively reducing collisions and friction during conveying and sorting, keeping the onion breakage rate below 0.5%.
Intelligent Control System: Equipped with a 7-inch touchscreen display, the system supports multiple languages, including Chinese and English. Five to eight weight-grading levels can be set with a single click. It also features data storage, automatically recording daily and monthly production data such as the number of grades and the percentage of each grade. This facilitates production management and data analysis, and supports remote fault diagnosis, simplifying equipment maintenance.
Improving the added value and market competitiveness of onion products: Accurate weight grading allows companies to sort onions into different grades by weight. 例如, large onions can be used for high-end gift packaging or export, while small and medium-sized onions can be used for further processing (such as onion rings and onion sauce), achieving "high quality and high price." According to customer feedback, the unit price of graded onion products can increase by 15%-20%, significantly improving the company's profit margin.
Ensuring production stability and meeting order delivery requirements: The equipment supports 24/7 continuous operation with a failure rate of less than 1%, ensuring stable production line output and avoiding order delays caused by labor efficiency fluctuations or staff shortages. During seasonal onion processing peaks, the equipment can quickly increase production capacity, helping companies to promptly process large quantities of raw materials, seize market opportunities, and reduce raw material backlogs and losses.
Reduce product loss and reduce cost: The food-grade soft silicone protective structure and arc-shaped transition design keep the onion breakage rate below 0.5%. Compared to the 5%-8% breakage rate of manual grading, this reduces the loss of 4,500-7,500 onions per 100,000 onions processed. Furthermore, precise grading prevents the waste of high-quality onions mixed with lower-grade ones, thereby improving raw material utilization.
Simplify production management and support digital transformation: The equipment's production data storage and export function automatically generates daily grading reports. Enterprises can clearly understand information such as onion yield by grade and equipment operating hours without manual statistics, providing data support for production planning adjustments and raw material procurement. The remote fault diagnosis function reduces equipment maintenance wait times, shortening the average repair time to less than 2 小时, ensuring continuous production line operation and helping enterprises achieve digital and efficient production management.
总之, the High Precision Onion Vegetable Weight Grading Machine is a high-performance device designed specifically for onion grading, featuring precise weighing, rapid processing, adaptability to the unique properties of onions, and intelligent control. It not only improves grading accuracy and reduces labor costs, but also helps you increase the market value of your onion products, improve shipping efficiency, and enhance quality competitiveness.
