Drying Seafood Is Hard on Equipment
Squid (墨鱼), mussels, fish and other seafood are dried in warm, salt-laden air that destroys ordinary exchangers within a season. The right core pays for itself by surviving the environment and recovering exhaust heat.
Cores That Survive Salt Spray
- 316L stainless plate cores: cross-flow, salt-spray resistant, easy to wash.
- Polymer (PP) air-to-air cores: fully corrosion-proof for the harshest brine-laden exhaust.
- Recover heat from drying exhaust to preheat incoming process air and cut fuel cost.
Typical Lines
- Dried squid, mussels (淡菜) and small fish (丁香鱼, 巴浪鱼) hot-air drying.
- Coastal processor drying rooms with high ambient salinity.

Survival Details
The difference between a core that lasts a season and one that lasts years is in the details: 316L stainless resists salt spray and washes clean, while a polymer core is fully immune to brine and suits the harshest coastal exhaust, so choose on lifecycle cost rather than first price. Mount the core where it can be pulled and rinsed on the regular wash-down cycle, keep a drain for the condensate it drops, and avoid any design that lets salt-laden condensate sit on a surface. Recovering heat from the drying exhaust to preheat incoming process air is what pays the bill, but only if the core survives the environment to keep doing it. For specifiers, the one question that matters is the rated salt-spray test result in writing, because a core without that rating is a guess in a coastal room.
Spec Check
For specifiers the one question that matters is the rated salt-spray test result in writing, because a core without that rating is a guess in a coastal room and the failure shows up as corrosion mid-season. Choose 316L where wash-down access is good and a polymer core where the brine is harsh or access is poor, and price both on lifecycle rather than first cost. Mount the core where it can be pulled and rinsed on the regular wash-down cycle and keep a drain for condensate, then track fuel per kilogram dried against the pre-core baseline so the saving from preheating incoming air is visible and the upgrade stays on the books as a managed asset.
