Grape harvest cooling tunnel
Ensure optimal grape quality for winemaking by precisely controlling temperature with a mobile cooling tunnel, reducing oxidation risks right after harvest.

Rapidly Cools and Preserves Harvested Grapes
The Grape Harvest Cooling Tunnel from The SERAP Group, developed in partnership with Linde Gas, offers a state-of-the-art cryogenic cooling solution for winemaking operations. Utilizing AISI 304 stainless steel construction and an insulated inline tunnel, it operates effectively with both liquid nitrogen (LN2) and carbon dioxide (CO2) to provide rapid and uniform temperature reduction. Applications span across wine production stages, ensuring the quality of red, white, rosé, sparkling, and fortified wines. The tunnel’s design supports processing a full or de-stalked harvest, accommodating continuous mobile operations with automated capabilities for streamlined integration into reception lines.
Featuring a variable speed stainless steel conveyor belt and a user-friendly interface, this equipment reduces the need for constant operator attention. On the output side, grapes are enveloped in a neutral gas atmosphere to minimize oxidation risk. Its compact and mobile nature expedites installation and enhances efficiency while contributing to energy savings. Cleaning and maintenance are simplified through easy access to modular components, aligning with hygiene standards. Customization options enhance its adaptability across diverse winemaking processes, offering technical support for specific operational needs.
