Introduction of potato grading production line:

Potato grading line is a series of automated equipment that can quickly clean, grade, and sort potatoes based on their sizes, weights. Its core value lies in using machines to replace high-intensity manual labor, which is not only efficient, but also standardized and reliable.

1. Lifting and Soaking

Lift the potatoes from the sink of the hopper to the production line, while preliminarily soaking and softening the surface soil for easy cleaning in the future.

Machine: Soaking hoister.

2. Manual sorting

Function: The workers removes damaged and spoiled potatoes, as well as residual skin.

Machine: Sorting conveyor.

3. Spray & bubble washing

Function: Remove sediment and impurities on the surface of potatoes with air bubbles high pressure spray water.

Machine: Bubble washer machine. 

4. Washing and peeling, or just washing without peeling

Function: Remove potato skin through the rotational friction of the brush rollers, or only remove sediment with soft brush rollers while without peeling, at the same time, rinse the potatoes with high-pressure spray water.

Machine: Continuous washing and peeling machine, or soft brush washer machine.

5. Grading

Function: Classify potatoes according to their size (diameter or weight), different sizes of potatoes are sorted, for after processing or direct sales.

Machine: Potato Sorting Machine.

6. Air drying

Potatoes are blown by wind from multiple angles during rolling transportation, thereby removing moisture from the surface of the potatoes, for subsequent processing or storage.

Machine: Air dryer.
