Against the drawbacks of low efficiency, poor precision and easy mistakes of manual batching, we launch this micro multi-ingredient automatic batching weighing machine. The equipment is mainly used for quantitative weighing and dosing of various small-batch additives in food and other industries. It supports 8 to 48 different raw materials, and the electronic weighing scale ranges from 10kg to 50kg. It adopts diversified feeding structures including double screws, belt conveyor and electromagnetic vibration feeder, and is equipped with roller conveyor, independent dust collector and complete control system. The whole machine is made of SUS304 stainless steel for material bins, which meets food-grade production requirements. The system realizes full-process automatic operation from feeding, weighing, conveying to re-inspection. It also has feeding error prevention, automatic rechecking and rejection functions to control weighing tolerance strictly. Combined with formula management, data tracking and barcode printing modules, it realizes standardized, intelligent and traceable production, greatly upgrading the automation level of batching links.
First of all, it delivers excellent weighing accuracy. The static weighing accuracy reaches ≤±0.1% F.S, dynamic accuracy ≤±0.15% F.S and cumulative accuracy ≤±0.2% F.S, with display resolution of 1g, 2g and 5g, fully meeting high-standard production demands.
Secondly, it has dual protection of automatic rechecking and feeding error prevention. The rear weighing station will recheck the data of the previous station; once exceeding the set tolerance, the system will automatically reject the unqualified materials to reduce waste. Before feeding raw materials into bins, workers need to scan material labels first, and the system will unlock the bin only after confirmation to prevent wrong feeding.
Thirdly, the equipment has strong production capacity, with continuous output of 240–360 bags per shift, and multi-station simultaneous weighing further improves efficiency to 200–600 bags per shift.
Besides, it is eco-friendly and safe. The matched dust removal system controls exhaust dust content below 8mg/m³, realizing dust-free production; the overall noise is lower than 75dB, and safety interlock devices ensure operation safety.
In addition, it supports remote management and after-sales service, uses imported and joint-venture core components for stable operation. The field bus system can automatically detect faults and send alarm prompts for easy maintenance. The human-machine interface supports both Chinese and English, and the rectangular circulating line can be arranged in single or double floors, with flexible layout to adapt to different factory spaces. The minimum bin quantity is 6 sets and the maximum is 48 sets, with strong compatibility for various production demands. The loading hopper volume is 200 litres with a load of 150kg, and the weighing speed is 20kg per 120 seconds. The whole equipment features low energy consumption, reliable performance and long service life.

The machine is composed of material storage area, feeding system, roller conveyor, weighing unit, dust collector and electric control system. Raw materials are sent out from storage bins via screw, belt or electromagnetic vibration feeding. Then materials are transported to the weighing unit by roller conveyor for precise batching. After primary weighing, materials will be sent to the recheck station for secondary verification. If the weight is out of tolerance, the materials will be automatically rejected. All feeding operations need label scanning verification to avoid material mixing. The dust collector collects flying dust during operation to protect the workshop environment. The central control system uniformly manages formulas, material data and production records, and supports barcode printing and quality tracking.
A1: It is mainly applicable to powder, granular and flake raw materials, including various food additives, rubber and plastic auxiliaries, chemical raw materials, feed additives and pharmaceutical ingredients. It is widely used in food, rubber, plastic, chemical industry, feed and pharmaceutical production.
A2: The equipment can be configured with 6 to 48 material bins, supporting 8 to 48 different types of materials for simultaneous dosing and weighing, which can meet the batching demands of complex formulas.
A3: The subsequent weighing station will recheck the weight data from the previous station. If the weighing error exceeds the preset precision range, the system will stop the weighing of this batch. The materials will continue to move along the conveyor line and be automatically rejected when passing through the valve checking device, effectively reducing raw material waste caused by inaccurate weighing.
A4: Before feeding materials into the storage tank, operators must scan the label on the material bag. The control system will compare the information. Only after confirming the material is correct can the bin be opened for feeding; otherwise, the feeding channel will remain locked to prevent wrong material feeding.
A5: It is equipped with Chinese and English dual-language human-machine interface, with clear operating pages and simple operation. The field bus system can automatically detect abnormal conditions, locate faults and give troubleshooting prompts. Core parts are high-quality imported and joint-venture products with low failure rate. The modular structure is convenient for daily inspection and maintenance.
A6: Yes. Each unit is equipped with an independent bag-type dust collector. The dust content in the exhausted air after treatment is lower than 8mg/m³. The fully enclosed structure prevents dust flying and material leakage, realizing dust-free production and avoiding raw material loss.
