Specifications of Foodline 2T/H Potato Processing Equipment Line for Washing Drying Sorting
This potato washing machine utilizes water flow and air bubble to wash potatoes.
| Equipment dimensions | 4000 × 1500 × 1200 mm |
| Air pump power | 1.5 kW |
| Water pump power | 1.5 kW |
| Gear motor power | 0.75 kW |
| Voltage | 380V, 50Hz |
| Mesh belt width | 800 mm |
| Mesh belt material | 304 stainless steel |
| Speed control | Manual |
The air bubble helps remove soil and other impurities from potato surfaces. After washing, the conveyor belt transports potatoes to the equipment for the next processing stage.


The parallel air dryer uses a powerful airflow to remove surface moisture from washed potatoes.
| Equipment dimensions | 5000 × 1000 × 1300 mm |
| Conveyor power | 0.75 kW |
| Blower power | 0.75 kW/unit |
| Number of blowers | 10 units |
| Conveyor width | 800 mm |
| Conveyor type | Roller type |
| Speed control | Manual |
| Main frame | 50 × 50 × 1.5 mm stainless steel square tubing |
| Blower support plate | 2.0 mm stainless steel plate |
As potatoes pass through the drying section, the airflow blows away surface moisture. Dried potatoes can then proceed to the grader for size sorting.


The roller grading machine sorts potatoes based on size.
| Model | 4-grade sorting |
| Equipment dimensions | Approx. 4000 × 800 mm |
| Sorting capacity | 3 t/h |
| Sorting method | By potato diameter |
| Operating voltage | 380V, 50Hz |
| Total power | 2.2 kW |
| Waterproof rating | IP65 |
| Material | 304 stainless steel |
The gap between rollers gradually changes along the sorting section, allowing potatoes of different sizes to enter their corresponding collection zones.
Foodline can adjust potato processing equipment line configurations for different needs. For example, we build 5t/h potato washing drying grading line for higher-capacity processing.
Highlights of Foodline 2T/H Potato Processing Machine line
1. Continuous Processing Layout: Washing, drying, and sorting units are linked sequentially to form a continuous production line suitable for large-scale potato handling.
2. Washing and Conveying at the Same Time: Potatoes move forward during the washing process, reducing the need for manual handling between processing stages.
3. Air Drying for Surface Moisture Removal: Washed potatoes enter the drying zone. Powerful airflow from fans removes surface moisture, preparing them for subsequent sorting, packaging, or storage.
4. Multiple Sorting Options: Roller-type, drum-type, or track-type sorters can be configured to meet specific sorting requirements.
5. Food-Grade Design: Components in direct contact with potatoes are made of food-grade stainless steel, ensuring easy cleaning and maintenance.
6. Scalable to Processing Needs: The production line can be configured to suit small, medium, or large-scale potato processing operations.
Foodline can provide suitable potato processing equipment line based on your raw materials, capacity, and processing requirements.
