Customized solution for dual working conditions

We can make food clean and dust-free models, chemical explosion-proof and anti-corrosion models according to needs, adapting to the workshop standards of different industries;

High-precision fluid metering and filling

The refrigerant/food medium filling accuracy is ±0.2g, eliminating excessive filling and lack of material losses;

Explosion-proof safety complete protection

Chemical motors, sensors, and electronic controls are all explosion-proof grade Ex d II BT4, and the pipelines are anti-corrosion and resistant to refrigerant corrosion;

Dry vacuum waterless treatment leak detection

There is no liquid contact throughout the process to avoid food contamination and dilution and deterioration of chemical materials;

Batch full process traceability

Bind materials, filling parameters, and testing data according to production batches to meet food safety and chemical industry regulatory traceability requirements;

Modular segmented delivery

The loading, leak detection and sorting units can be separated and used separately, which is suitable for small and medium-sized factories to be put into operation in stages.

Production line area

Standard 40m×3.5m, segmented single unit covers an area of 6~10㎡

Clean/explosion-proof automated feeding and conveying

The food production line uses 304 stainless steel dust-free belts for transportation, with no debris or oil-contaminated materials; the chemical production line uses explosion-proof motors + anti-static conveyor belts to automatically transfer metal tanks and pipeline workpieces, with no risk of sparks throughout the process. The robot automatically grabs and positions the workpiece, and the servo positioning accuracy is ±0.1mm, ensuring accurate filling alignment.

High-precision fluid automatic filling function

Independent metering pump unit, real-time closed-loop weighing and calibration, automatically completes quantitative filling of refrigerants, edible oils, and chemical heat transfer media; automatic blocking and sealing after filling is completed, synchronously records the filling and weight data of each piece, and automatically alarms and diverts materials for shortage and excess to reduce raw material losses.

Vacuum seal leak detection function

After the workpiece is filled, it is sent to the vacuum leak detection station to detect micro-leakage in the tank welds and sealing interfaces; the food version prevents packaging leakage and deterioration, and the chemical version prevents volatilization and leakage of refrigerants and dangerous media. The entire process is dry detection, with no water pollution and no material dilution.

Visual appearance sorting function

Dust-proof industrial cameras detect tank deformation, skewed sealing lids, missing labels, and weld defects; defective products are automatically diverted to the repair area, and qualified products are automatically stacked and unloaded, replacing 4 to 6 sorting and quality inspection workers.

Batch digital control

The system records raw material storage time, filling parameters, and leak detection results according to production batches. The data is docked with MES to generate batch quality inspection reports, which meets food safety production regulations and chemical hazardous chemicals traceability supervision requirements, and supports regulatory authorities to retrieve complete production files at any time.

Commercial value: Raw material filling loss is reduced by 70%, manual quality inspection and sorting positions are completely eliminated, and the defective rate of food and chemical products is reduced to less than 0.4%; the explosion-proof integrated production line avoids safety hazards in the production of hazardous chemicals, reduces safety supervision and rectification costs, and a single production line recovers equipment investment in 1.8 years.
