Tea fixation (shaqing) is the critical first step in tea processing that stops enzymatic oxidation, locks in fresh aroma, and shapes the final flavor profile. The heating source of the fixation machine directly impacts temperature stability, heating uniformity, and even the unique characteristics of the tea. DELI ASSISTANT, a leading manufacturer of tea machinery, offers three mainstream heating types—gas, electric, and wood/coal—each tailored to different production needs and tea quality requirements. Let’s dive into their differences, typical models, and selection guidelines to help you make the best choice.
Stable & efficient heating: Provides continuous, uniform heat output, avoiding local overheating or under-fixation that ruins tea freshness.
Controllable temperature: Adjustable heat intensity adapts to various teas (e.g., oolong, black tea) and batch sizes.
Clean & low-residue: No smoke or ash contamination, ensuring the tea’s pure aroma and clean taste.
High production capacity: Ideal for medium to large tea factories with consistent output demands.

Prioritize flavor characteristics: Choose wood/coal heating for traditional smoky teas, electric heating for fresh and delicate teas, and gas heating for balanced, pure-flavor teas.
Match production scale: Small workshops (≤50 kg/h) fit electric models; medium-large factories (≥80 kg/h) benefit from gas or continuous wood/coal models.
Consider environmental regulations: Electric or gas models are preferred in areas with strict emission limits; wood/coal models require additional dust removal equipment.
Focus on tea grade: High-end teas demand electric or gas models for precision; bulk teas can use cost-effective wood/coal models.
