The most economic scheme captures the highest-grade streams first for the most valuable uses, preheating process water or space heating, and routes lower-grade ventilation air to make-up air preheat. Following the heat ladder avoids bolting on recovery where passive methods would do.<\/p>\n<h2>Grease, particulates, and cleanability<\/h2>\n<p>Process exhaust in food plants often carries grease, moisture, and food particulates, so the core must be cleanable on a routine schedule without disassembly headaches. Stainless or coated aluminum cores that tolerate wash-down, plus accessible drainage, keep hygiene audits straightforward. A fouled core not only loses effectiveness but also becomes a contamination and fire-risk point if neglected.<\/p>\n<h2>Control and verification<\/h2>\n<p>Tie recovery to production schedules where possible, since many lines run in shifts, so part-load behavior matters. Track effectiveness and pressure drop from commissioning so fouling shows as a trend rather than an unplanned stop. In cold climates, watch the exhaust side for frost when preheating incoming air.
