Designed and manufactured by Wuxi Xielì (Wuxi Xielì Automation Equipment Co., Ltd.), the “ 20 The “hopper pre-weighing mobile railcar automated batching system” has recently been put into full-load operation at a leading domestic manufacturer of freshness-preserving agents (deoxidizers), delivering satisfactory results in terms of equipment stability, batching accuracy, and efficiency.

This follows 2019 In [year], Wuxi Xielì and Jiangnan University jointly designed and manufactured a mobile batching system specifically for food preservatives. , Following its successful implementation at a leading domestic fresh-keeping agent (deoxidizer) company, this marks the second successful deployment in the food fresh-keeping agent (deoxidizer) industry.

    Why has Wuxi Xielì’s system been successfully applied once again in the food preservative (deoxidizer) industry?

The core reason lies in its “high-precision batching” and “environmentally friendly, dust-free” technical features, which perfectly meet the dual stringent requirements of deoxidizer production for formulation accuracy and workshop environmental conditions.

Specifically, this can be analyzed from the following dimensions:

1.  Achieving ultimate precision in the core formulation

The core operating principle of food deoxidizers is the chemical reaction between active iron powder and oxygen, which effectively absorbs oxygen. To ensure efficient and rapid oxygen absorption, the ingredients of the deoxidizer—such as active iron powder, nano-silica-based oxides, sodium carbonate decahydrate, activated carbon, and edible salt—must be blended in extremely precise, scientifically determined proportions.

High-precision control: Wuxi Xielì’s automated batching system boasts millimeter-level precision and fully computerized, automatic control, ensuring absolute accuracy in the proportioning of multiple raw materials. This is critical for guaranteeing the deoxidizer’s ultimate oxygen-absorption capacity and reaction stability.

Poka-yoke and Traceability: This system can be equipped with barcode-based error-proofing and data traceability features, which help prevent human errors in ingredient addition, ensure high batch-to-batch consistency of the deoxidizer, and comply with safety standards for food-contact materials.

2.  Adapting to flexible production with multiple product varieties and small batch sizes

The food deoxidizer industry offers a wide range of specifications—different models are required to meet the varying oxygen-absorption needs of food packages of different sizes—and market demand is rapidly evolving.

Mobile and Flexible Layout: The components of the mobile batching system are relatively independent, allowing for a flexible layout that can easily accommodate rapid recipe changes. This flexible production capability is ideally suited for deoxidizer manufacturers to meet order requirements involving multiple specifications and batch sizes.

3.  Meets hygienic and safety standards for food-grade production.

Although deoxidizers are not consumed directly, they are auxiliary products used for food preservation, and their manufacturing environment is subject to stringent hygiene and safety requirements.

Automation and Isolation: This system enables unmanned or minimally manned operation of the batching process, with the control room physically isolated from the production system. This not only reduces direct contact between personnel and raw materials, thereby lowering the risk of cross-contamination, but also significantly enhances production efficiency and safety.

4. Addressing the Environmental Challenges of Powder Materials

The primary raw materials for deoxidizers—such as iron powder, activated carbon, and edible salt—are all fine powders or granular materials. During conventional batching processes, these materials readily generate substantial dust, leading not only to raw material waste but also to severe contamination of the workshop environment and, in some cases, posing a serious safety hazard of dust explosions.

Wuxi Xielì’s system features a mobile railcar for automated material feeding and discharging, along with a telescopic dust-proof design, and can be equipped with a pressure-balanced centralized dust-collection system. This solution perfectly addresses the environmental requirement of “zero dust emissions during the batching process” in deoxidizer production, significantly improving working conditions for employees and aligning with the green manufacturing standards of modern chemical plants.

In summary, Leveraging its deep technical expertise in powder blending, Wuxi Xielì’s equipment suite has seamlessly transferred the advantages of “high precision, intelligent operation, and dust-free processing” to the deoxidizer industry. This has enabled deoxidizer manufacturers to address key pain points in traditional production—such as inaccurate formulations, high labor costs, and severe dust pollution—thereby earning widespread recognition and adoption across the industry.
