Introduction
In food processing, cold chain logistics, central catering, and prefabricated food industries, turnover baskets and plastic trays are reusable logistics carriers that run through the entire production and distribution process. However, residual food debris, oil stains, and microbial contamination on used baskets and trays have always been a key hidden danger affecting workshop hygiene and product safety.
Traditional manual cleaning is time-consuming, labor-intensive, and unstable in cleaning effect, which can no longer meet modern industrial standardized hygiene requirements. The automatic turnover basket and tray washing machine is designed for mass industrial cleaning. It realizes one-stop automatic operations of high-pressure cleaning, degreasing, sterilization, and drying, effectively solving the problems of incomplete manual cleaning, high water consumption, and high labor costs.
This article will elaborate on the core structural features and complete working principle of the industrial basket tray washing machine, helping you understand how this equipment improves workshop cleaning efficiency and hygiene standards.
Core Structural Features of Basket & Tray Washing Machine
The industrial turnover basket washing machine adopts a tunnel-type integrated design. The whole machine is modularly structured with reasonable layout, strong stability, and convenient maintenance. All key components follow food-grade hygiene standards, adapting to long-term continuous industrial operation.
1. Food-grade Stainless Steel Body, Corrosion-resistant & No Hygiene Dead Ends
The whole equipment is made of SUS304 stainless steel, which is acid and alkali resistant, rust-proof, and high-temperature resistant. All water-contact parts adopt seamless welding technology to avoid dirt accumulation and mold growth. The smooth surface is easy to clean and maintain, fully complying with food production safety specifications. Compared with ordinary iron and plastic structures, it has a longer service life and lower failure rate.
2. Variable-speed Conveying System, Stable & Anti-jamming
Equipped with high-strength stainless steel chain or mesh belt conveying structure, the operation is stable without slipping or deviation. Matching with a frequency conversion speed regulation motor, the conveying speed is adjustable according to the dirt degree, basket size, and production capacity demand, which can perfectly adapt to various common specifications of plastic turnover baskets, logistics trays, and material pallets.
In addition, the automatic pressure rod design effectively prevents the baskets from flipping, stacking or blocking during operation, ensuring continuous and smooth feeding and discharging without manual monitoring.
3. 360° Full-covered High-pressure Spray System, No Blind Spots
Different from single-direction flushing of traditional cleaning equipment, this machine adopts multi-angle three-dimensional spray layout, with spray pipes arranged on the top, bottom, left, and right of the cleaning tunnel. Equipped with detachable and angle-adjustable food-grade high-pressure nozzles, it forms a dense high-pressure water net.
The high-impact water flow can completely flush the inner cavity, surface, gaps, and bottom corners of the turnover basket, thoroughly stripping stubborn oil stains, sauce residues, and food particles, realizing 360° dead-angle-free deep cleaning.
4. Circulating Filtration Water System, Water-saving & Environmentally Friendly
The equipment is equipped with an independent multi-tank water circulation system, including pre-washing tank, hot water degreasing tank, and clean water rinsing tank. The water bodies of each section are circulated independently to avoid cross-contamination of dirt.
Each water tank is equipped with a multi-layer filtering device, which can automatically intercept food residues and sundries to prevent nozzle blockage. The recycled water is filtered and precipitated for reuse, reducing overall water consumption by more than 70% compared with manual cleaning, which greatly reduces production water costs and meets industrial energy-saving and environmental protection requirements.
5. Intelligent Constant Temperature Heating System, Efficient Degreasing & Sterilization
Support two heating modes: electric heating and steam heating, adaptable to different factory energy conditions. Equipped with a high-precision PID constant temperature control system, the water temperature can be freely adjusted from normal temperature to 80°C with small temperature fluctuation.
Proper high-temperature hot water can quickly emulsify and decompose oil stains. The high-temperature water above 82°C can assist in sterilization, effectively killing harmful bacteria such as Escherichia coli and Salmonella on the surface of baskets and trays, ensuring that the cleaned containers meet food-grade hygiene standards.
6. PLC Intelligent Control System, Easy Operation & Safe
Adopt PLC + touch screen integrated intelligent control, with one-key start and automatic cycle operation. Users can preset parameters such as cleaning temperature, conveying speed, and spraying time according to different cleaning needs.
The equipment is built-in with overload, leakage, and water shortage protection functions. The operation interface is simple and intuitive, requiring no professional technical operation, which greatly reduces the threshold of use and operation risks.
7. Customizable Functional Modules
According to customer industry and cleaning standards, optional upgrade modules are available, including rotary brush cleaning unit, automatic disinfection spraying unit, and hot air drying unit, realizing integrated cleaning, disinfection, and drying to meet higher-standard hygiene production needs.
Working Principle of Automatic Basket Tray Washing Machine
The turnover basket tray washing machine adopts a tunnel-type continuous assembly line operation mode. The dirty baskets and trays are driven by the conveying system to pass through multiple functional sections in sequence, completing the whole process from preliminary decontamination, deep degreasing, rinsing and disinfection to drying and discharging.
Step 1: Automatic Feeding & Conveying
Place the dirty turnover baskets or trays flat on the feeding end conveyor belt. The equipment drives the materials to enter the cleaning tunnel at a uniform and adjustable speed, realizing continuous batch feeding.
Step 2: Pre-washing & Preliminary Decontamination
In the pre-washing section, high-pressure cold water is used to flush the surface and gaps of the baskets, washing away floating dust, loose food residues, and large particles of dirt. This step reduces the dirt load for the main cleaning section and avoids excessive residue blocking the circulating water system.
Step 3: High-temperature Hot Water Main Cleaning & Degreasing
This is the core decontamination process. The circulating hot water (40-80°C) is sprayed at high pressure to fully contact the surface of the containers. The high-temperature water temperature emulsifies and decomposes greasy dirt and aged stains. With the impact of high-pressure water flow, stubborn dirt is quickly peeled off. The optional brush module can further polish and clean the bottom and side gaps of the baskets to ensure thorough decontamination.
Step 4: Fresh Water Rinsing
After main cleaning, the clean high-pressure fresh water is used for overall rinsing to completely wash away residual detergent, oil stains and suspended impurities on the surface of the baskets and trays, ensuring no chemical residue and meeting food safety standards.
Step 5: High-temperature Disinfection (Optional)
Through high-temperature hot water spraying or food-grade disinfectant atomization spraying, it realizes comprehensive sterilization and disinfection, eliminates residual bacteria on the surface of the containers, and avoids cross-contamination in repeated use.
Step 6: Hot Air Drying (Optional)
The high-strength air knife removes surface water droplets, and the circulating hot air system dries the containers comprehensively. The cleaned baskets and trays are dry and residue-free, which can be directly put back into production and circulation, effectively inhibiting bacterial growth caused by residual water stains.
Step 7: Automatic Discharging
The cleaned and dried qualified baskets and trays are automatically transported to the discharging end, realizing continuous batch output and greatly improving overall cleaning efficiency.
