[0043] Step 4: The first group of holding baskets transfers the potatoes to the peeling box through the connecting part between the pretreatment box and the peeling box, and then moves them back to the steam heating bin to receive new potatoes and drive them to the steam heating bin for heating. The second group of holding baskets drives the potatoes to move to the cooling bin for cooling.
