High-Temperature Waste Heat Recovery for Food Drying Rooms — Plate Air-to-Air Heat Exchanger for Cost Reduction and Efficiency Improvement
During the operation of food drying rooms, a large amount of high-temperature and humid exhaust air is discharged directly to the atmosphere, resulting in significant energy loss. By installing a plate air-to-air waste heat recovery heat exchanger, the sensible heat from the exhaust air can be efficiently recovered and reused to preheat the incoming fresh air or make-up air, without changing the original drying process.
The exchanger adopts a multi-layer plate cross-flow design, ensuring complete separation between exhaust air and fresh air, with no cross-contamination, fully meeting hygiene requirements for food processing. The system operates mainly with fans and does not require additional heat sources, effectively reducing the consumption of gas, electricity, or steam used for heating.
In applications such as fruit and vegetable drying, meat processing, herbal materials, and seasoning production, the plate air-to-air heat exchanger improves overall thermal efficiency, shortens heating time, and lowers energy consumption per unit of product, providing a reliable solution for food manufacturers to achieve cost reduction and sustainable, energy-efficient production.
