The shutter unit of the EA-100K forming machine is designed with great ingenuity to prevent dough from sticking.

In order to prevent dough from sticking, our engineers minimized the contact time and surface when the shutter unit cut and form the products. Although there is no doubt that the structure of the shutter unit has a significant impact on production, the shutter speed is the key to success. At the moment the shutter opens and closes, a product is formed perfect and pleasing. (Note: EA-100K is no longer available. The updated model is EA-100KA.
