The FRY-TECH FOOD EQUIPMENTS PVT LTD Cooling Screw Conveyor (also known as a Screw Heat Exchanger) has become a critical piece of equipment for potato processors in Ahmedabad. After steaming or blanching, potatoes are too hot to slice or fry immediately. This machine uses a jacketed cooling system to drop the product temperature rapidly, ensuring starch stability and a crispier final product.

1. How the Cooling Technology Works

Unlike a standard conveyor, the cooling version uses an indirect heat exchange method:

• The Cooling Jacket: The "U" trough or pipe through which the potatoes travel is surrounded by a hollow jacket filled with circulating chilled water or brine.
• The Hollow Flight (Advanced): In high-end FRY-TECH models, the internal screw itself is hollow. Chilled water flows inside the rotating screw flights, providing a 360-degree cooling surface that touches every potato slice.
• Temperature Control: Connected to an external Chiller Unit, the system can drop potato temperatures from 95 C down to 25 C in a single pass.

. Technical Specifications

Pricing depends heavily on the length of the conveyor and whether the screw itself is cooled.

. Why use a Screw over a Belt for Cooling?

• Space Saving: A screw conveyor can cool products while moving them vertically or at steep inclines, taking up 70% less floor space than a long cooling belt.
• Hygiene: The enclosed "U" trough prevents dust or contaminants from touching the peeled potatoes.
• No Sticking: The constant "tumbling" action of the screw prevents potato slices from clumping together, which is a common problem on belt conveyors.
