Potatoes are washed and peeled thoroughly by brush washing and peeling machine, which is mainly used in large capacity (800-5000 kg/h)washing and peeling work. The brush rollers (8-15 pieces) are made of soft nylon material. The potatoes peeld by it has smooth surface with minimum peeling losses. The residual skin, eyes and green portions are trimmed manually.
Peeled potatoes are cut into strips by potato cutting machine. The thickness can be adjusted freely by increasing or decreasing the spacers between the blades. The cross section of the sticks ranges between 7 and 12 mm and is generally 10 mm. The length of the strips can be 5-7 cm. The strips are graded for size. Too short, thin strips and discolored ones are removed.
The strips are blanched in water at 70-95 degrees Celsius for several minutes to inhibition active enzyme, keep the fresh flavor of potato strips, increases the softness, and resulting in uniform fry color. This process also removes some of the sugars from the surface of sticks, mitigating the browning reaction during frying.
The strips are partially dried to remove excess moisture. The French fries dewatering machine adopts centrifugal principle to dehydrate the surface water of the French fries after blanching, guarantees the maximum dewatering degree. If the strips are meant to be fried, the water content should be near 70-75%; if they’re to be cooked in an oven, the water content should be around 65-70%; and for microwave frozen Fries, it’s a measly 55-60%.
The “par fry” is a cooking stage where the strips are cooked for about two minutes in oil at 175-185°C. People buy the par-fried fries from supermarket or grocery, and then fry them secondly at home or in fast restaurant. The second fry is at 180°C for about 2 minutes or at 150°C for about 5 minutes.
