Gentle, Even Drying Protects Quality
Chestnuts, walnuts, peanuts, bamboo shoots, fruits and other produce dry best at low, stable temperatures. Air-to-air heat recovery lets you hold that profile while cutting the energy bill.
What Recovery Delivers
- Preheat drying air with recovered exhaust heat — lower fuel or electricity per kilogram dried.
- Stable temperature protects color, oil content and shelf life of nuts and fruit.
- Polymer or hydrophilic-aluminum cores suit the humid, acidic drying air.
Common Applications
- Chestnuts and walnuts low-temperature baking.
- Peanuts, bamboo shoots (竹笋) and tropical fruit (雪莲果) drying.
- Combined produce-and-herb drying rooms.

Quality Link
In low-temperature drying the energy saving and the product quality are the same project: holding a gentle, stable profile protects color, oil content and shelf life, and recovering exhaust heat is what makes that profile affordable to run. Use a polymer or hydrophilic-aluminum core suited to the humid, slightly acidic drying air, and size the core to the airflow so the preheat holds steady through the batch rather than swinging as load changes. Keep the recovery loop isolated from the product air where hygiene matters, which also meets food-safety expectations for nuts and fruit lines. Track the energy per kilogram dried against a baseline so the quality gain and the saving are both visible, and revisit the core material if the crop mix changes, since a more acidic or saltier product can shift the corrosion duty the core was rated for.
Sizing Note
Hold the drying profile steady by sizing the core to the airflow rather than the throughput, so the preheat does not swing as batches change and the quality stays consistent batch to batch. Use a polymer or hydrophilic-aluminum core suited to the humid, slightly acidic drying air, and keep the recovery loop isolated from product air wherever hygiene matters, which also meets food-safety expectations for nuts and fruit lines. Track energy per kilogram dried against a baseline from the first run, because that single figure shows both the quality gain and the saving, and revisit the core material if the crop mix shifts to something more acidic or saltier that changes the corrosion duty it was rated for.
