Automatic series
Automatic Multi-Stage Ultrasonic Cleaning Line with Conveyor & Dual Drying
The 300L fully automatic six-tank ultrasonic cleaning line combines two-stage ultrasonic cleaning, filtration, bubbling rinsing, air-knife dewatering, centrifugal drying, and hot-air circulation drying. With 7200W ultrasonic power and 18kW heating per ultrasonic tank, SUS316 wet-process tanks, conveyor transfer, and PLC control, it is designed for continuous industrial batch cleaning.
Continuous Cleaning for Production-Line Applications
For manufacturers processing repeated batches of industrial components, cleaning may involve several separate operations before parts are ready for inspection, assembly, coating, or other downstream processes.
Repeated manual transfer between cleaning, rinsing, and drying equipment can interrupt production flow and make it more difficult to coordinate processing time between stages.
This automated line combines the complete process into one system:
Primary Ultrasonic Cleaning → Secondary Ultrasonic Cleaning → Bubbling Rinsing → Air Knife Dewatering → Centrifugal Drying → Hot Air Circulation Drying
Workpieces are carried in stainless steel cleaning baskets and transferred through the process by the conveyor system, reducing repeated manual handling between individual treatment stages.
How the Automated Cleaning Line Works
The reference system uses six dedicated process stations, with each stage performing a specific cleaning, rinsing, dewatering, or drying function.
Tank 1 — Primary Ultrasonic Cleaning
The first tank performs the primary ultrasonic cleaning process and integrates ultrasonic cleaning, heating, filtration, circulation, and workpiece agitation.
The 850 × 850 × 500 mm tank is constructed from 2.0 mm SUS316 stainless steel.
Four ultrasonic plate assemblies are installed around the tank:
- 2 on the bottom
- 1 on the front
- 1 on the rear
Together they contain 144 ultrasonic transducers, operating at 40kHz with 7200W ultrasonic power.
An 18kW heating system and a dedicated filtration and circulation system support the primary cleaning process.
Tank 2 — Secondary Ultrasonic Cleaning
The second tank provides another ultrasonic cleaning stage before rinsing.
It uses the same 850 × 850 × 500 mm, 2.0 mm SUS316 tank construction and another four ultrasonic plate assemblies with 144 transducers.
The ultrasonic system operates at 40kHz / 7200W, with 18kW heating power.
This provides a second ultrasonic treatment stage within the complete cleaning process.
Tank 3 — Bubbling Rinsing
After ultrasonic cleaning, the parts enter the bubbling rinsing stage.
The 850 × 850 × 500 mm tank is manufactured from 2.0 mm SUS316 stainless steel and incorporates bubbling pipes connected to a high-pressure blower.
An air filter is included in the bubbling system.
This stage provides liquid movement around the workpieces before they proceed to dewatering and drying.
Shared Agitation System — Tanks 1–3
The first three wet-process tanks share one workpiece agitation system.
This provides mechanical workpiece movement during the ultrasonic cleaning and bubbling rinsing stages.
The exact movement arrangement can be configured according to the workpiece, basket, and cleaning process.
Tank 4 — Air Knife Dewatering
The fourth station removes surface water after rinsing.
The 850 × 850 × 500 mm chamber is constructed from 2.0 mm SUS304 stainless steel and uses air knives arranged around all four sides.
The air knives can move back and forth while connected to a high-pressure blower, providing sweeping airflow around the workpieces before they enter the drying stages.
Tank 5 — Centrifugal Drying
The fifth station uses centrifugal action to remove retained water from the workpieces.
The chamber measures 850 × 850 × 500 mm and uses 2.0 mm SUS304 stainless steel construction.
The centrifugal drying system provides 12kW drying power and is equipped with a high-efficiency air purifier.
Tank 6 — Hot Air Circulation Drying
The final station uses circulating hot air to complete the drying process.
The 850 × 850 × 500 mm chamber is manufactured from 2.0 mm SUS304 stainless steel and provides 12kW drying power.
A high-efficiency air purifier is also integrated into the drying system.
After this stage, the workpieces proceed to unloading or the next manufacturing process.

Why This Multi-Stage Process?
Two Ultrasonic Cleaning Stages
The system uses two dedicated ultrasonic tanks before rinsing.
Each tank provides 144 transducers, 7200W ultrasonic power, 40kHz frequency, and 18kW heating in the reference configuration.
Separating ultrasonic treatment into two stages provides a more controlled cleaning sequence for parts requiring more than one ultrasonic treatment before rinsing.
Bubbling Rinsing
After the ultrasonic stages, bubbling rinsing provides liquid movement around the workpieces before the drying process begins.
The tank uses bubbling pipes, a high-pressure blower, and an air filter.
Three-Step Water Removal
Instead of relying on a single drying method, the system uses:
Air Knife Dewatering → Centrifugal Drying → Hot Air Circulation Drying
Air knives first remove surface water, centrifugal action provides additional mechanical water removal, and circulating hot air completes the drying process.
Core System Features
Conveyor-Based Transfer
Workpieces are transported through the production line using a conveyor system and stainless steel cleaning baskets.
This connects the six treatment stages into one coordinated process and reduces repeated manual transfer between separate machines.
40kHz Ultrasonic Cleaning
Both ultrasonic cleaning tanks operate at 40kHz in the reference configuration.
Each tank uses 144 transducers with 7200W ultrasonic power distributed through ultrasonic plate assemblies mounted on the bottom, front, and rear surfaces.
Filtration & Circulation
Tank 1 incorporates a dedicated filtration and circulation system to support cleaning-liquid management during the primary ultrasonic process.
Shared Workpiece Agitation
Tanks 1–3 share one agitation system to provide workpiece movement during the wet-process stages.
SUS316 Wet-Process Tanks
The first three liquid-processing tanks use 2.0 mm SUS316 stainless steel.
The subsequent dewatering and drying chambers use 2.0 mm SUS304 stainless steel.
Four-Side Sweeping Air Knives
The dewatering chamber uses air knives positioned on four sides with reciprocating movement and high-pressure airflow.
Centrifugal + Hot Air Drying
The system combines centrifugal drying with hot-air circulation rather than relying on heated drying alone.
Both drying stages provide 12kW drying power in the reference configuration.
PLC-Controlled Production Line
PLC control coordinates the automated cleaning line and conveyor-based production process.

Frequently Asked Questions
Why does this system use two ultrasonic cleaning tanks?
The reference configuration uses two separate ultrasonic treatment stages before bubbling rinsing. Each ultrasonic tank provides 144 transducers, 7200W ultrasonic power, 40kHz frequency, and 18kW heating.
The final number of ultrasonic stages should be determined according to the workpiece, contamination, and required cleaning process.
Why are the first three tanks made from SUS316?
The three wet-process tanks use 2.0 mm SUS316 stainless steel, while the dewatering and drying sections use SUS304.
This provides a more corrosion-resistant material configuration for the liquid-processing section. Final material selection should also consider the cleaning chemistry and operating conditions.
What is the shared agitation system?
Tanks 1–3 share a mechanical agitation system that provides workpiece movement during the wet-process stages.
The movement configuration can be adapted according to the basket, workpiece, and cleaning requirements.
How does the air-knife dewatering system work?
Air knives are arranged around four sides of the chamber and can move back and forth while connected to a high-pressure blower.
This provides sweeping airflow around the workpieces to remove surface water before centrifugal and hot-air drying.
Why use both centrifugal and hot-air drying?
The two stages use different water-removal methods.
Centrifugal drying uses mechanical rotational action to remove retained water, while hot-air circulation provides the final heated drying stage.
Can the tank dimensions or process stages be changed?
Yes. Tank dimensions, station quantity, ultrasonic configuration, basket design, agitation, drying process, conveyor layout, and electrical configuration can be adapted according to the project requirements.
