Dry Herbs Without Losing the Good Stuff
Medicinal crops such as honeysuckle (金银花) and other herbs lose active compounds when overheated. Low-temperature heat-recovery drying protects quality while lowering cost.
Why Low-Temp Recovery
- Holds drying air in the gentle range that preserves volatile actives and color.
- Recovers exhaust latent heat to preheat incoming air, cutting energy per batch.
- Epoxy or polymer cores resist the moist, acidic herbal exhaust.
Typical Lines
- Honeysuckle, chrysanthemum and traditional medicinal herbs.
- Combined food-and-medicinal drying rooms.

Protecting Actives
Medicinal crops lose value the moment volatile actives are driven off by excess heat, so the recovery design exists to hold the drying air in the gentle range, not to push throughput. A closed, isolated loop with an epoxy or polymer core keeps the moist, acidic herbal exhaust away from supply air and recovers latent heat without contaminating the product stream, which also satisfies the cleanliness expectations of a GMP-style operation. Size the core to hold the target temperature band at the typical batch load, and control it from the room setpoint so the profile stays flat across the run. For buyers, the practical check is whether the supplier can state the rated temperature and chemical resistance in writing and confirm a washable surface, because herbs are unforgiving and a core that fouls or corrodes quietly erodes both potency and payback.
Procurement Note
For buyers the practical check is whether the supplier states the rated temperature and chemical resistance in writing and confirms a washable surface, because herbs are unforgiving and a core that fouls or corrodes quietly erodes both potency and payback. Keep the loop closed and isolated so the moist, acidic herbal exhaust never reaches supply air, satisfying the cleanliness a GMP-style operation expects, and size the core to hold the target band at typical batch load. Review the material rating if the herb mix changes to something more acidic or oily, since that shifts the chemical duty the original core was chosen for and can shorten its service life unnoticed.
