How can vegetable packaging achieve high efficiency and precision?

2025-02-01

In the operation process of vegetables from the fields to the market, the packaging link plays a crucial - role and can directly affect the freshness - keeping period of vegetables. As an integrated weighing and packaging device, the Multihead Weigher has, to a certain extent, improved the efficiency and accuracy of packaging, bringing many conveniences and improvements to the entire vegetable industry chain.

The Multihead Weigher Working Principle

It is a combination of multi - unit collaborative weighing and intelligent optimization. Specifically, multiple independent weighing units (weighing hoppers) simultaneously weigh the materials, and the computer control system conducts real - time analysis and optimized combination of the data in each weighing unit, so as to quickly and accurately reach the preset target weight, and finally complete the packaging. The whole process is both fast and accurate to a certain degree.

The operation process of vegetables in a multi head weighe machine

● It sends those vegetables down onto a conveyor belt that carries them to the feeding port of the Multihead Weigher Machine.The bottom of the feeding port is often equipped with vibrating feeder and other devices. Function: It is used to evenly and slowly feed the vegetables into the hoppers above the weighing hoppers of the multi - head weigher through vibration. (The vibration frequency and amplitude can be adjusted according to the properties of vegetables in distribution process, like size, softness and hardness, shape, etc., so as to ensure speed and avoid damage.)

● From the feeding hopper, vegetables are distributed to several independent multi - passages weighing hopper of the multi - head weigher. The general multi - head weighers have many hoppers, such as 14 Heads Multihead Weigher, 10 heads multihead weigher, etc., and can also be customized according to the required. Each weighing hopper is equipped with high - precision weighing sensors to measure the actual weight of vegetables in real time, which lays a foundation for subsequent weighing combinations.

● Then, the weighing part begins. Weights of the vegetables in each of weighing hoppers are monitored in real - time by the weighing sensors and transmitted to the control system as weight data. The control system will then analyze and process the weight data in each weighing hopper according to the target weight preset by the user. (E.g., if the target value is 500 grams, then the control system calculates which combination of the weight of even all hoppers is closest to this amount.)

● The control system uses complex algorithms to calculate the weight combinations of vegetables in each weighing hopper. It will try different combinations of weighing hoppers to find the combination whose weight is most in line with the target packaging weight.

● After determining the optimal combination, the control system will issue an instruction to open the discharge ports of the corresponding weighing hoppers, so that the vegetables in these weighing hoppers fall into the packaging containers (such as plastic bags, cartons, etc.) below to complete the final packaging process.
