2. Technology Principle
IUSUMMER Ion-Lens equipment uses a high-voltage physical field to generate free electrons and active species in a controlled treatment zone. The ion-lens structure guides and concentrates the ion or electron flow, while UV/photoelectric effects may further increase active particles inside the disinfection chamber. The treatment is positioned as a low-temperature physical process for reducing microbial activity on suitable exposed surfaces or materials.
| Technology element | Function | Customer value | Relevant application |
|---|---|---|---|
| High-voltage physical field | Generates electrons and active species in the treatment area. | Supports physical microbial reduction without routine liquid chemicals. | Carton tunnel, pallet tunnel, grain treatment, seed treatment |
| Ion-lens structure | Constrains and directs ion or electron flow toward the treatment path. | Improves treatment-zone control and equipment differentiation. | Moving conveyor, exposed-layer material flow, treatment chamber |
| UV/photoelectric assistance | Increases active particles in the chamber in source-described designs. | Adds another physical contribution to the treatment environment. | Tunnel-type surface disinfection |

5. Cold-Chain and Package Surface Disinfection
Cold-chain warehouses, food factories, and logistics centers often rely on manual spraying or intermittent surface sanitation for cartons, pallets, and turnover boxes. Tunnel-type physical disinfection can help standardize the treatment step, reduce wet handling, and create operation records for quality teams.
| Use case | Object | Workflow location | Customer value |
|---|---|---|---|
| Inbound package treatment | Cartons, crates, turnover boxes | Receiving dock or sorting line | More consistent surface treatment before storage or sorting. |
| Outbound package treatment | Cartons or palletized goods | Before dispatch, export loading, or customer transfer | Documented hygiene-control step before shipment. |
