FEATURED CASE · LINE-FLOW LAYOUT
Continuous cleaning lines engineered for every scenario
A whole stack of dirty boxes is placed at the infeed of the line to start the process.
The machine automatically separates the stack layer by layer, releasing individual box stacks.
Each stack is further split into single boxes, which are then lined up in order to enter the washing tunnel.
Each box is turned 180° upside down to empty any solid food residue before washing.
Through multiple high-pressure spray stages, oil and residue are powerfully removed from both the surface and interior of the crate.
Clean water is applied to flush away any remaining detergent and fine particles.
Boxes are flipped 180° again to return to their normal upright position for use.
Clean and dry boxes are automatically arranged and stacked in preset layers.
The completed stacks are conveyed to the discharge point and removed as a whole stack.
Automatically separates lids from meal boxes and plates, allowing lids and containers to enter the washing process separately, avoiding cleaning dead spots caused by stacking and improving cleanliness and washing efficiency.
Integrates debris removal, soaking, washing, rinsing, high-temperature sanitizing, and drying. After tableware enters, the entire process is completed automatically, outputting clean and dry tableware ready for direct use or temporary storage.
Crushes and dehydrates food waste, achieving a volume reduction rate of up to 80%, significantly reducing food waste disposal costs, preventing accumulation and decay, and keeping the washing room clean and odor-free.
Full sets of tableware directly enter the debris removal machine. Large food residues are removed from surfaces by high-pressure water or mechanical means. Residue is automatically separated and discharged, reducing the load for subsequent washing.
Automatically identifies and sorts tableware and food waste. Tableware is conveyed to the dishwasher for cleaning, while food waste is sent to the processing channel for classified treatment.
Large capacity design to meet a large number of tableware cleaning needs; High degree of automation, set cleaning, disinfection, drying in one, can be flexibly customized according to customer needs.
It is used for automatic recycling of tableware before cleaning, which can quickly and continuously transport tableware from the restaurant to the cleaning area, improve the efficiency of tableware recycling, improve the restaurant environment, and optional chopsticks spoon recycling cabinet.

The cutlery is separated from the food residue, the cutlery is automatically transferred to a special cleaning area, and the residue collection device is included in the slag collector, and the residue is automatically filtered out into the reserved container.
Soaking and pre-washing the filtered tableware can quickly dissolve the grease and soften the caked stains on the tableware.
CORE TECHNOLOGY
Fans are matched according to container structure and conveying direction, creating a continuous and concentrated air-flow to blow off water droplets attached to container surfaces and edges. The air knife angle, height, and airflow coverage can be adjusted based on the product, reducing residual moisture after washing and seamlessly connecting with subsequent drying, palletizing, and turnover processes.
Before Blow-Off
After Blow-Off
Liweishi matches water pumps, nozzles, and spray piping according to container structure and soil characteristics, flushing container surfaces with multi-directional water flow. By integrating cleaning temperature, detergent, and conveying speed, it creates cleaning solutions adapted to different operating conditions.
