室内萎凋与加温萎凋工艺

Indoor withering takes place in well-ventilated rooms with leaves on multi-tier racks, relying on natural airflow for 48-72 hours—quality approaches sun-withered but with more stable output. Heated withering uses temperature/humidity-controlled troughs at 30-38°C for 24-36 hours, ideal for large-scale production. It is efficient but lacks the aroma complexity of natural methods. Most factories use 'combined withering'—2-3 hours of sun followed by indoor completion—balancing efficiency and quality.
