Product Range

Cart Washing Machine

High-capacity automated cleaning for 200L standard meat trolleys and transport carts

The Cart Washing Machine is designed for meat processing facilities that require thorough, hygienic cleaning of 200L standard meat trolleys. Built as a specialized industrial washing machine for food applications, this cart washer combines high-pressure washing, precise rinsing, and electronic detergent dosing into a single automated cleaning cycle — eliminating manual labor while ensuring every surface of the trolley is thoroughly sanitized.

Capacity: Up to 60 carts/hour  

Chamber: Dual-chamber system （washing + rinsing）  

Spray Coverage: 360° rotating spray arm with no dead angles

Crate Washing Machine HE-3600

Three-stage cleaning for medium-volume crate processing

The HE-3600 is a three-stage cleaning system designed for medium-volume operations. Its dual-track chain conveyor keeps crates stable and centered while adjustable side rails accommodate different container sizes. The two-tank system progressively cleans crates through pre-wash, main-wash, and final wash stages.

Capacity: 300–600 pieces/hour  

Cleaning Stages: 3 (Pre-wash → Main-wash → Washing)  

Water Tanks: 2

Crate Washing Machine HE-4800

Four-stage cleaning for high-volume crate processing

The HE-4800 features a four-stage cleaning system with three water tanks, offering higher throughput and improved cleanliness through an additional dedicated rinsing stage. Fresh water rinse removes all remaining detergent residue before the final clean water wash, delivering superior sanitation results for high-volume operations.

Capacity: 600–1,000 pieces/hour  

Cleaning Stages: 4 (Pre-wash → Main-wash → Rinsing → Washing)  

Water Tanks: 3

Technical Specifications Comparison

Key Features

SUS304 Food-Grade Construction

Entire machine body, tanks, chains, and nozzles built from SUS304 stainless steel for maximum corrosion resistance, durability, and compliance with food safety standards.

360° Rotating Spray Arm (Cart Washer)

Engineered spray arm with strategically positioned nozzles delivers all-round, dead-angle-free coverage — every surface of the trolley, interior and exterior, receives thorough high-pressure cleaning.

Multi-Stage Progressive Cleaning (Crate Washers)

Three or four cleaning stages progressively remove different types of contamination — pre-wash softens surface residue, main-wash detaches stubborn buildup, and the final wash/sterilization stage ensures food-safe cleanliness.

Dual-Track Chain Conveyor (Crate Washers)

Unique dual-track loop chain design keeps crates stable and centered throughout the cleaning process. Adjustable side rails accommodate different container widths up to 650 mm.

Water Recycling System

Integrated filtration systems capture debris and recirculate wash water between stages — significantly reducing water consumption without compromising cleaning quality.

Electronic Detergent Dosing (Cart Washer)

Automated chemical injection controls detergent dosage throughout the cleaning cycle, ensuring consistent cleaning results and preventing overuse of cleaning agents.

PLC Automated Control

Full PLC programming controls loading, washing, rinsing, and unloading sequences. Each operation step can be individually adjusted and monitored for precise process control.

Optional Air Drying Section (Crate Washers)

Add-on drying tunnel equipped with scroll high-pressure blowers removes residual water droplets from cleaned crates for immediate reuse — 2,200 mm drying section with dual 5.5 kW fans.

Application Scenarios

Working Principle

Cart Washing Machine Flow

Operator loads 200L meat cart onto the loading system

    ↓

Trolley enters the sealed washing chamber

    ↓

Rotating spray arm activates — 360° high-pressure spray

covers all interior and exterior surfaces with no dead angles

    ↓

Electronic detergent dosing system injects precise

amounts of cleaning agent into the wash cycle

    ↓

Wash water passes through integrated filtration system

and recirculates for the next cleaning cycle

    ↓

Trolley transfers to the rinsing chamber

    ↓

Fresh water rinse removes all remaining detergent

and loosened residue from the meat cart surfaces

    ↓

Trolley advances to the unloading station

    ↓

Operator removes the clean, sanitized meat trolley

ready for immediate reuse in production

    ↓

（Optional） Machine self-cleaning cycle activates

to maintain internal hygiene between production runs

Crate Washing Machine Flow

Turnover crates loaded onto dual-track conveyor

    ↓

Stage 1: Pre-wash

High-flow water simulates traditional soaking —

softens and loosens surface residue on crates

    ↓

Stage 2: Main-wash

High-pressure spray detaches stubborn stains

and organic buildup from crate surfaces

    ↓

Stage 3: Rinsing （HE-4800 only）

Circulating clean water flushes away remaining

detergent residue from previous stages

    ↓

Stage 4: Clean Water Wash

Fresh water performs a final thorough rinse,

leaving crate surfaces clean with zero residue

    ↓

（Optional） Air Drying

Crates enter drying tunnel — scroll high-pressure

blowers remove residual water droplets for

immediate reuse

    ↓

Clean, sanitized crates exit the machine

FAQ

Q1: What size of containers can these machines handle?

A: The Cart Washing Machine is designed for 200L standard meat trolleys with a maximum lifting height of 2,160 mm — accommodating most standard 200L carts and trolleys used in the industry. The Crate Washing Machines handle containers up to 650 mm width × 350 mm height, including plastic baskets, crates, trays, boxes, pallets, and egg trays. If your facility uses non-standard sizes, we can customize the chamber dimensions, spray arm configuration, and conveyor width to accommodate your specific requirements.

Q2: How many containers can the machines clean per hour?

A: The Cart Washing Machine has a maximum capacity of 60 carts per hour. The Crate Washing Machine HE-3600 processes 300–600 pieces per hour, while the HE-4800 handles 600–1,000 pieces per hour. Actual throughput may vary depending on soil level and selected wash cycle duration. For higher volume requirements, we can discuss customized configurations or multi-unit installations.

Q3: What heating methods are available?

A: Standard models use steam heating — the Cart Washer requires 30 kW heating power at 0.1 MPa steam pressure, consuming approximately 100 kg of steam per hour. The Crate Washers feature intelligent steam heating control that maintains optimal sterilization temperatures （82°C or 95°C） automatically. If your facility does not have a steam supply, alternative heating options can be discussed during the configuration stage.

Q4: How does the water recycling system work?

A: Both systems feature integrated filtration and circulation systems. In the Cart Washer, wash water passes through filters to remove debris and recirculates for the next cycle — fresh water is used only for the final rinse stage. In the Crate Washers, water flows counter-currently from the clean wash tank to the pre-wash tank, maximizing water reuse across stages. This design significantly reduces overall water consumption compared to single-pass cleaning.

Q5: Is operator training required?

A: The PLC automated control system manages the entire cleaning cycle with minimal operator intervention — simply position the container and press start. We provide detailed operational training and maintenance guidance with every installation. The modular design enables straightforward routine maintenance, primarily involving filter cleaning and nozzle inspection.

Q6: Can the machines clean themselves?

A: Yes. The Cart Washing Machine has a built-in automatic self-cleaning function that flushes and sanitizes internal chambers, spray arms, and filtration systems after production runs. Crate Washing Machines include automatic tank draining and flushing cycles for internal maintenance. These features help maintain consistent hygiene standards and extend equipment service life.

Q7: What control options are available for crate washing machines?

A: We offer two control options: 

(1) PLC Smart Control with touchscreen HMI for programmable cleaning cycles, automated monitoring, and data logging — recommended for larger facilities; 

(2) Standard push-button control panel for straightforward, reliable manual operation — a cost-effective choice for smaller operations. Both display water temperature and working status in real time.
