IQF Tunnel Freezer for Potato Application

High product quality and sustainable freezers
GEA’s experience in the food industry offers customers optimal performance coupled with energy-efficient freezing and cooling systems. Considering the significant growth predicted for the French fry sector, food manufacturers are well placed to meet the increasing demand for these products with innovative processing and freezing solutions that really make a difference in the battle to prevent climate change.

The current challenge for frozen potato processors is to reduce energy and meet sustainability targets in an effective way.

A significant amount of energy is required to freeze potato products. For a 30,000kg/hr French fry freezing tunnel, about 6MW of refrigeration capacity at different temperature levels is needed to gradually reduce the product to frozen.

Freezer equipment design is vital for food safety, optimum performance throughout production, and energy savings, especially when handling massive quantities of French fries! Additionally, the right equipment can significantly reduce downtimes with fast, efficient cleaning factored in. 

GEA IQF tunnel freezers for potato applications are specifically designed for pre-cooling and freezing process steps with multizone temperature freezer embedding unique features for hygiene, efficiency, high uptime, and reliability. GEA experts in frozen food applications ensure that the best solution is identified for your product and select a tunnel configuration to guarantee quality and safe products throughout your entire freezing process.

Enabling reductions in CO2 emissions

GEA, a leading technology provider to the food sector has more than 160 of its French fry freezer tunnels operating worldwide and recently conducted extensive research and development into significantly improving the sustainability and energy consumption in industrial freezing equipment. 

We recently obtained a certification of CO2 emission reduction for its French Fry IQF tunnel freezer with Water Precool as a result of a proven 22% to 57% drop in CO2 emissions depending on the country and conditions therein.2  Results were certified by Ramboll, an EU Taxonomy evaluation body. 

Proven CO2 emission reductions and energy-efficient consumption are part of the sustainable actions to contribute to, and reach GEA Group’s target to align with its Mission 2026 program.
