Working Principle

1. Loading & Conveying: Dirty crates are loaded manually or via an automatic conveyor (optional), and transported through the cleaning tunnel at a controllable speed by a chain-driven conveyor or stainless steel mesh belt, ensuring stable and smooth transfer without jamming or damage to crates.
2. Pre-Wash Stage: Recycled water is sprayed at high flow to remove loose debris, large particles, and surface dust from crates. This stage softens stubborn residues (such as food scraps and oil stains) while reducing fresh water consumption, laying the foundation for thorough cleaning in subsequent stages. The water in this stage is filtered and recirculated to achieve resource conservation.
3. Main Wash Stage: High-pressure sprays (0.2-0.7MPa) of heated water (50-85℃ adjustable) mixed with food-grade detergent are applied to crates from multiple angles. Rotatable nozzles target all surfaces of crates—top, bottom, sides, and inner corners—effectively breaking down fats, oils, proteins, and stubborn stains that manual cleaning cannot remove. The detergent concentration is precisely controlled to ensure optimal cleaning effect while avoiding waste.
4. Rinse & Sanitizing Stage: After the main wash, crates pass through the rinse section, where clean heated water (or pure water for high-demand scenarios) removes residual detergent and dirt. For industries with strict hygiene requirements (such as food and pharmaceutical), an optional sanitizing rinse is available, which sprays food-grade disinfectant to eliminate bacteria, mold, and allergens, ensuring crates meet HACCP, FDA, and EU hygiene standards.
5. Drying (Optional): An optional high-efficiency air-drying system (electric or steam heating) blows cold or hot air from all sides to quickly remove surface moisture from crates, reducing crate turnover time and preventing secondary contamination. This stage is especially suitable for industries that require immediate reuse of crates, such as cold chain logistics and food processing.

Applications

• Food & Beverage Industry: Cleaning of crates used for fruits, vegetables, dairy products, meat, bakery products, and beverages. It effectively removes food residues, oil stains, and bacteria, ensuring food safety during storage and transportation. Applicable to fresh produce packhouses, dairy facilities, meat processing plants, and beverage factories.
• Agriculture & Horticulture: Cleaning of crates for agricultural products such as vegetables, fruits, and flowers, removing soil, pesticides, and dust, extending the freshness of agricultural products and facilitating subsequent storage and transportation.
• Logistics & Distribution: Cleaning of turnover crates used in warehouses, logistics hubs, and cold chain logistics. It solves the problem of cross-contamination caused by repeated use of crates, ensuring the safety of goods during transportation and improving logistics efficiency.
• Pharmaceutical & Healthcare Industry: Cleaning of crates for medical supplies, drugs, and medical devices. It meets strict hygiene standards, removes dust and pollutants, and avoids cross-contamination, ensuring the safety of medical products.
• Other Industries: Also applicable to the chemical industry (cleaning crates for chemical raw materials), automotive industry (cleaning crates for auto parts), catering industry (cleaning turnover baskets), and aquaculture industry (cleaning fish and seafood crates).

Product Advantages

1. Superior Hygiene & Compliance: The multi-stage cleaning and sanitizing process ensures that crates are free from bacteria, mold, and residues, fully complying with HACCP, FDA, and EU hygiene standards. The entire machine is made of SUS304 (or SUS316 optional) stainless steel, which is corrosion-resistant, rust-proof, easy to clean, and meets food-grade and pharmaceutical-grade hygiene requirements, avoiding secondary contamination.
2. High Efficiency & Labor Savings: The automatic operation replaces repetitive manual cleaning, reducing labor costs by 60%-80%. The cleaning capacity can be customized from 100 to 2000 crates per hour, which is 10-15 times that of manual cleaning. The adjustable conveyor speed (3-15 m/min) can be matched with your production line to achieve seamless connection and improve overall operational efficiency.
3. Energy & Water Saving: Equipped with a double-layer water circulation and filtration system, the water reuse rate reaches 80%以上, reducing water consumption to 0.5-0.6L per crate. The energy-efficient heating system (electric or gas heating optional) with precise temperature control reduces energy consumption by 30% compared with traditional equipment. The detergent dosing control system avoids excessive use of detergent, further reducing operating costs and achieving environmental protection goals.
4. Versatility & Customization: Suitable for cleaning various types and sizes of crates, baskets, trays, and pallets, including plastic, metal, and wooden crates. We provide free customized solutions based on your specific needs, such as adjusting the machine size, adding a drying system, dual-channel cleaning, or fully automatic palletizers, to meet the unique requirements of different industries and scenarios.
5. Durability & Easy Maintenance: The machine body is made of 3mm thick SUS304 stainless steel, with wear-resistant, corrosion-resistant, and impact-resistant properties, ensuring a service life of 8-10 years. The modular design and removable filters make daily maintenance and part replacement easy, reducing downtime. The intelligent control panel with built-in under-voltage protection ensures stable operation and easy operation.

6. Safe & User-Friendly: Equipped with safety protection devices (emergency stop button, protective cover, and overload protection) to avoid operational accidents. The PLC intelligent control panel allows one-click operation, with clear display of temperature, water pressure, and cleaning time, and can store multiple cleaning parameters for different crates, making operation simple even for unskilled workers. A viewing window is also available for real-time monitoring of the cleaning process.

   FAQ (Frequently Asked Questions)

   1. Can the machine be customized for different crate sizes and types? Yes, absolutely. Our Crate Washing Machine supports all sizes and types of crates (plastic, metal, wooden, etc.). We will provide free customized solutions based on your specific crate dimensions, contamination level, cleaning capacity, and other needs, such as adjusting the conveyor width, nozzle angle, and machine size. We can also customize special functions like dual-channel cleaning or automatic palletizing according to your production line requirements.
   2. How long does it take to install and debug the machine? The standard installation and debugging time is 3-5 working days.
