Cleaning automation equipment manufacturer — From one machine to a full cleaning system

BRAND POSITIONING

FROM ONE MACHINE TO A FULL CLEANING SYSTEM

Guangzhou Liweishi Environmental Protection Technology Co., Ltd. specializes in the manufacturing and sales of commercial cleaning equipment. The company focuses on the R&D of commercial dishwashers, central kitchen cleaning equipment, commercial crate/container washers, and palletizing systems, providing one-stop commercial cleaning solutions to clients worldwide.

Why Cleaning Automation

The four limits of manual washing.

As volume grows, hand and semi-manual washing breaks down on labor, speed, consistency and continuity.

High Labor Costs

Manual washing relies on a large workforce and pushes up operating costs.

Low Cleaning Efficiency

Manual and semi-manual washing cannot keep up with growing volume.

Inconsistent Standards

Results vary between operators and shifts, creating hygiene risk.

No Continuous Operation

Peak demand easily blocks the whole workflow in large-scale projects.

Core Business

One system, four cleaning fronts.

Each front is modular, and engineered to connect into a single continuous production line.

Integrated, Cost-Saving, Efficient

Core Technology

Three technologies behind the cleaning result.

Matched to container structure, soil type and conveying speed — not a one-size-fits-all wash.

01 / Blow-Off

High-Speed Air Knife Blow-Off

Fans are matched to container structure and conveying direction, creating a continuous, concentrated airflow that blows droplets off container surfaces and edges. Air-knife angle, height and coverage are adjustable by product.

Configured on demand to container size, structure and conveying speed.
Configurable top, bottom and side air knives for multi-directional water removal.
Fits crates, baskets and trays.
SUS304 stainless air knives — easy to clean and maintain.

02 / Spray

High-Pressure Spray Cleaning

We match pumps, nozzles and spray piping to container structure and soil characteristics, flushing surfaces with multi-directional water flow. Cleaning temperature, detergent and conveying speed work together as one process.

Pressure and flow configured to soil type and material.
Nozzle layout covering bottom and side walls.
Temperature, detergent and time integrated for the cleaning need.
Fits crates, baskets and trays.

03 / Heat Recovery

Heat Recovery Technology

LIWEISHI recovers process heat to cut running cost against traditional dishwashers, while holding wash and rinse temperatures stable — lower power draw per unit, less water per hour.
