Crate Washer vs Meat Trolley Washer: Choosing the Right Container Washer

Blog Post - Industry News | Publish date: 2026-09-04

Introduction

Walk into the wash room of almost any food factory and you will find two kinds of containers waiting for attention: plastic crates, baskets and trays that carry raw material and product through the plant, and 200-litre stainless steel trolleys that move meat, offal and by-products between departments. Both are cleaned for the same reason - containers that touch food must not carry contamination to the next product - but they are not cleaned the same way.

Choosing the wrong container washer is an expensive mistake. A machine that is too small creates a nightly bottleneck at the end of every shift; an oversized system wastes water, steam and valuable floor space. This guide compares Henger’s crate washing machines and meat trolley washers - what each machine does, the published specifications, and how to decide which one, or which combination, belongs in your plant.

Why Container Washing Needs to Be More Than a Hose

· Crates and trolleys touch food directly. A soiled crate stored overnight can seed the next day’s product with residues and microorganisms.

· Manual washing is inconsistent. Rinsing by hose depends on the operator, the lighting and the time available at the end of a shift - and it cannot be documented for auditors.

· Containers move between hygiene zones. In meat and poultry plants, crates and trolleys travel between raw, processing and cold storage areas, making consistent sanitation a cross-contamination control point.

· Labour and water. Hand washing consumes significant labour and often more water than a recirculating machine, with less predictable results.

Crate Washer: Built for High-Volume Plastic Crates

A crate washing machine is a continuous tunnel system designed for turnover containers made of plastic - crates, baskets, trays, boxes, pallets and egg trays. Crates feed through on a dual-track conveyor and pass several cleaning stages in sequence, combining high-pressure sprays with heated water for reliable sanitation.

Henger offers two crate washing machine models: the HE-3600 for medium volumes and the HE-4800 for high-throughput lines. Both are built from SUS304 food-grade stainless steel with a recirculating water system and optional air drying tunnel.

Meat Trolley Washer: Purpose-Built for 200L Trolleys

A meat trolley washer is a different kind of machine. Instead of a continuous tunnel, it is a chamber-based system that washes stainless steel 200L meat trolleys one at a time or in small batches, with a rotating spray arm delivering full-coverage cleaning of the interior and exterior surfaces.

Henger’s meat trolley washer combines high-pressure washing, rinsing and electronic detergent dosing in an automated cycle controlled by PLC, with a closed-loop water filtration and recycling system.

Key published features include a dual-chamber wash-and-rinse design, 360-degree rotating spray arm, PLC control with photoelectric safety sensors, and a self-cleaning cycle between production runs.

Head-to-Head Comparison

The two machines are complementary rather than competing - but they are often confused. The comparison below summarises the practical differences.

How to Choose: Four Questions That Decide

· 1. What are you washing? Plastic crates and trays point to a crate washer; 200L stainless steel trolleys point to a trolley washer. If you run both container types - common in slaughterhouses and large processors - you may need two machines.

· 2. What is your peak volume? Crate lines handle hundreds of units per hour (300-1,000 by model); trolley washers are sized per cart, up to 60 per hour. Count the containers you must clean in the shortest available window.

· 3. What space and utilities do you have? A tunnel-type crate washer needs 3.6-4.8 m of line length; a trolley washer needs a chamber footprint of about 2.8 m. Both use steam heating, and the trolley washer requires tap water pressure of at least 0.2 MPa.

· 4. Do containers need to be dry before reuse? If crates must go straight back to production or into dry storage, add the air drying tunnel option. Trolleys, by contrast, are typically reused wet after rinsing.

These are general engineering guidelines, not binding rules - Henger’s engineers can size either machine from your container mix, shift volume and floor plan.

One Supplier, One Wash Room Strategy

Container washing rarely stops at a single machine. A complete wash room in a meat or food plant often combines a crate washing machine for plastic crates, a meat trolley washer for 200L carts, an automatic tunnel-type trash can and bin washer for bins and waste containers, and apron washers for workwear - all coordinated under Henger’s Tools Washing Solution. Sourcing from one manufacturer keeps stainless steel quality, water systems and service consistent across the whole wash room.

FAQ

Q1: What is the main difference between a crate washer and a meat trolley washer?

A crate washer is a continuous tunnel system for plastic crates, baskets and trays, processing hundreds of units per hour. A meat trolley washer is a chamber-based machine that cleans 200L stainless steel trolleys with a rotating spray arm, up to about 60 trolleys per hour.

Q2: Can the crate washer handle different crate sizes?

Yes. The dual-track conveyor has adjustable guide rails that accommodate crates, baskets, trays and boxes with widths up to 650 mm and heights up to 350 mm.

Q3: How many crates can the HE-3600 and HE-4800 wash?

The HE-3600 processes 300-600 crates per hour with a 3-stage cleaning process. The HE-4800 processes 600-1,000 crates per hour with a 4-stage process that adds an extra rinsing tank.

Q4: How fast is the meat trolley washer?

The standard 200L model cleans up to 60 trolleys per hour. Actual throughput depends on soil level and the selected cycle; higher volumes can be handled with customised configurations.

Q5: Do we need both machines?

It depends on your container mix. Plants that handle both plastic crates and 200L metal trolleys - such as slaughterhouses and large processors - typically need both lines. If you mainly wash one container type, start with the matching machine.

Q6: What utilities do these machines require?

Both use steam heating (the trolley washer at 30 kW). The crate washer is sized by line length (3.6-4.8 m) and the trolley washer needs about 0.2 MPa tap water pressure. Henger provides free layout drawings to confirm fit before purchase.

Closing Call to Action

Crates and trolleys both carry food through your plant, but they need different cleaning machines. Match the machine to the container, size it to your peak shift volume, and check the space and utilities available in your wash room - the comparison table above gives you the starting point.
