Tea Withering Machine vs Oolong Tea Shaking Machine

2025-12-16 14:30:58

1.Tea Withering Machine

The core function of a tea withering machine is withering and mild fermentation. By controlling temperature, humidity, and ventilation, it reduces moisture in fresh leaves, activates enzyme activity, and lays the foundation for moisture redistribution and aroma transformation during subsequent shaking. Main models include withering racks, withering heads, and integrated withering troughs, suitable for different production scales.

  • Core Models: DL-TQJ-20 (bamboo withering rack), DL-TQJ-20QB (stainless steel withering rack), DL-6CWD-803 (integrated withering trough), DL-6CWD-907 (large withering trough)
  • Key Parameters:
    • Material: Bamboo/galvanized steel/stainless steel (adapting to different hygiene standards and cost needs)
    • Capacity: 50kg per rack (DL-TQJ-20), 50-220kg per batch (withering trough series)
    • Heating Method: Heating wire (power 18-24KW) with fans for uniform ventilation
    • Application: Small to large tea factories, usable independently or as part of a production line.

2.Oolong Tea Shaking Machine

The core function of an oolong tea shaking machine is collision and friction. Rotating drums drive tea leaves to collide with each other, slightly damaging leaf cells, promoting oxidation of tea polyphenols and enzymes, and facilitating moisture transport from mesophyll to veins ("moisture redistribution"). This ultimately forms the unique aroma of oolong tea and the "green leaves with red edges" quality characteristic. Two types are available: steel drum with hot air and bamboo drum.

  • Core Models: DL-6CZQ-D110-3 (steel drum with hot air), DL-6CYQT-90250 (bamboo drum)
  • Key Parameters:
    • Material: Galvanized steel/stainless steel (steel drum), bamboo (bamboo drum)
    • Capacity: 32-200kg per batch (120-192kg/batch for bamboo drum, 150-200kg/batch for steel drum)
    • Drive Method: Motor-driven (power 0.75-2.2KW) with adjustable drum speed (0-30r/min)
    • Application: Specialized in oolong tea production; bamboo drums suit small-medium tea gardens pursuing traditional flavor, while steel drums with hot air suit large-scale production.

Core Differences Comparison

Comparison Dimension Tea Withering Machine Oolong Tea Shaking Machine
Core Function Withering and dehydration, mild fermentation, activating enzyme activity Collision and friction, promoting oxidation, forming aroma and appearance
Core Material Bamboo, galvanized steel, stainless steel Bamboo (traditional), galvanized steel/stainless steel (large-scale)
Capacity Range 50kg/rack - 220kg/batch 32kg/time - 200kg/batch
Power Configuration Heating power 18-24KW, fan power 0.25-0.37KW Motor power 0.75-2.2KW, no heating function (18KW heating for steel drum models)
Application Scene Pre-stage of all oolong tea production, suitable for various tea gardens Exclusive to oolong tea production; bamboo drum for traditional craftsmanship, steel drum for large-scale production
Operation Focus Controlling temperature, humidity, and ventilation volume Adjusting rotation speed and collision intensity

Selection Suggestions

  1. For small family tea gardens focusing on traditional handmade oolong tea, prioritize bamboo withering rack (DL-TQJ-20) + bamboo drum shaking machine (DL-6CYQT-90250) — low cost, aligned with traditional craftsmanship, and preserves tea's natural flavor.
  2. For medium tea factories with daily output of 50-200kg, recommend integrated withering trough (DL-6CWD-805) + steel drum shaking machine (DL-6CZQ-D110-3) — balancing efficiency and quality, supporting continuous production.
  3. For large-scale standardized tea enterprises, opt for continuous withering line + hot air steel drum shaking machine with temperature control systems to ensure batch stability.
