Cooling solutions for industrial processing lines
The tomato-processing industry—especially in its production-focused branch—faces demanding technical challenges: strong seasonality, continuous operation, and significant thermal loads at multiple stages. At Torraval, we develop efficient and robust cooling solutions tailored specifically for this type of food processing. Learn more about our industrial refrigeration solutions.
Thermal processes in tomato processing
During the production season (June to September), plants operate 24/7. Below are the primary stages, many requiring rigorous thermal control:
Reception and unloading
Sorting and classification
Blanching and preheating (facilitates peeling, juice extraction, and enzyme inactivation)
Peeling and chopping (generally using steam or hot water)
Extraction and refining
Concentration (an energy- and refrigeration-intensive process, often involving vacuum evaporation)
Pasteurization / Sterilization (a brief but intense heat treatment to ensure microbiological stability)
Hot or cold filling (depending on whether aseptic sealing is required)
Cooling and storage (essential for preserving quality and preventing overcooking)
Cooling solutions for the tomato industry
The large volumes of water used in production—often containing suspended or dissolved solids—demand cooling technologies suited to these conditions, such as evaporative and adiabatic condensers, ideal for industrial refrigeration applications.
Open cooling towers
Used to dissipate heat generated during process stages. Highly efficient and reliable, even when handling waters with high load.
Closed-loop cooling towers and dry coolers
Recommended in environments with poor water quality or where enhanced hygienic control is needed.
Industrial chillers
Needed in applications requiring process water at low temperatures (≤ 10 °C), particularly in closed circuits or aseptic lines.
Heat exchangers
Allow cooling of juices or pastes without direct contact with the cooling fluid, ensuring food quality and safety.
Cooling in demanding environments
Torraval cooling towers are engineered for uninterrupted operation during intensive campaigns. They can handle waters with high solid content and operate under severe environmental conditions. Additionally, they are designed for quick and safe maintenance—vital for industries that cannot afford prolonged downtime.
