3-Stage Rotary Drum Washers
The Arnold Machine 3-Stage Rotary Drum Washer is a general-purpose washer suited for high-volume cleaning applications and multiple part sizes and geometries. The machine is ideal for inline production processes where cleaning is required between stages, or for final wash applications.
The machine features a proven design of over 40 years with a stainless-steel drum available in two diameters: 18” and 24”. The cleaning cycle consists of a heated, pressurized wash stage, heated, pressurized rinse stage, and a heated, high-pressure blow-off stage. Stage lengths are configurable based on specific process requirements.
Drum speed is adjustable via the touchscreen and can be programmed into a part-specific recipe.
Custom machine sizes and configurations are also available if needed.
HOW 3-STAGE ROTARY DRUM WASHERS WORK
The 3-Stage Rotary Drum Washer uses a continuous rotational cleaning process for consistent exposure and high-throughput performance:
Loading: Parts are introduced into the rotating stainless steel drum through manual loading or automated/in-line material handling systems.
Stage 1 – Heated Wash: Heated, pressurized wash solution removes oils, debris, and contaminants while drum rotation ensures full surface exposure.
Stage 2 – Heated Rinse: A heated rinse stage removes residual cleaning solution and remaining soil.
Stage 3 – High-Pressure Blow-Off: Heated, high-velocity air removes excess moisture before discharge.
Discharge: Cleaned parts exit the drum ready for downstream processing or final assembly.
COMMON APPLICATIONS
3-Stage Rotary Drum Washers are ideal for high-volume operations requiring continuous cleaning between production stages or before final assembly.
Typical applications include:
- Stamped metal componentsMachined parts
- Automotive components
- Fasteners and hardware
- General industrial components requiring oil and debris removal
The system is commonly integrated inline between machining, forming, or coating operations.
