Tea Drying Equipment Comparison: Rotary Ovens vs Belt Dryers vs Tray Cabinets

2025-12-16 17:00:14

Introduction

Drying is the "flavor-setting key step" in tea processing, directly determining tea's aroma concentration, moisture content, and shelf life. Different production scales and tea varieties have distinct demands for drying equipment—tray cabinets suit small-batch and multi-variety production, rotary ovens balance uniformity and batch processing, and belt dryers meet large-scale continuous production needs. With 16 years of technical accumulation, DELI ASSISTANT, a leading tea machinery brand, has created a full range of drying equipment to accurately match diverse needs from handcrafted tea workshops to large-scale tea factories. This article will deeply analyze the differences, typical models, and selection logic of three core drying equipment, helping you precisely lock in the suitable solution.


I. Tray Cabinets: The Flexible Choice for Small-Batch & Multi-Variety Production

Core Advantages

  • Layered independent design allows simultaneous drying of different tea varieties, adapting to small-batch customized production.
  • Precise temperature control and gentle heat penetration maximize the retention of tea's delicate aroma, suitable for high-end loose tea and handcrafted tea.
  • Compact structure, simple operation, and low maintenance costs, no professional technicians required.
  • Supports multiple heating methods such as electric heating, environmentally friendly and pollution-free, meeting the site and policy needs of small tea workshops.

Typical Model: DL-6CH-5F

Parameter Specification
Overall Dimension 1070×810×1880 mm
Operating Voltage 380V 50Hz
Drying Area 5.76 ㎡
Tray Size 600×600×40 mm
Drying Layers 16 Layers
Heating Method Electric Heating
Adapted Capacity Suitable for small-batch production (≤10 kg per batch)
Core Feature Layered temperature control, flexible switching between tea varieties

II. Rotary Ovens: The Uniform Choice for Medium-Batch Production

Core Advantages

  • Rotating tray design ensures uniform heating of tea leaves, avoiding local over-drying or under-drying, and guaranteeing consistent batch quality.
  • Large drying area and strong batch processing capacity, adapting to the large-scale production needs of medium-sized tea factories.
  • Excellent sealing performance, reducing aroma loss, suitable for oolong tea and black tea that require locking in rich aroma.
  • Supports customization of stainless steel materials, corrosion-resistant and easy to clean, meeting food-grade production standards.

Typical Model: DL-6CHZ-14

Parameter Specification
Overall Dimension 1400×1320×2300 mm
Operating Voltage 380V 50Hz
Heating Power 18 KW
Tray Diameter 108-110 cm
Drying Layers 16 Layers
Effective Drying Area 14.6 ㎡
Capacity Per Batch 42-56 kg
Core Feature Rotational uniform heating, sealed aroma locking

III. Belt Dryers: The Efficient Choice for Large-Scale Production

Core Advantages

  • Continuous conveying design realizes automatic assembly line operation from feeding to discharging, doubling production efficiency.
  • Large drying area and high processing capacity, adapting to the large-scale mass production needs of large tea factories.
  • Supports multiple fuel heating (wood/coal/gas/electricity), flexibly adapting to energy conditions in different regions.
  • Precise adjustment of drying parameters, suitable for the drying needs of different tea varieties such as green tea, black tea, and dark tea.

Typical Model: DL-6CHBZ-20

Parameter Specification
Drying Box Dimension 5600×1910×2050 mm
Operating Voltage 220V/380V 50Hz
Total Power 8.8 KW
Drying Area 20 ㎡
Heating Method Wood/Coal/Gas/Diesel/Wood Pellets/Electric
Input Wet Tea Weight 100 kg/batch
Output Dried Tea Weight 55 kg/batch
Core Feature Continuous operation, high-efficiency mass production

Suitable Tea Types High-end loose tea, handcrafted tea, small-batch blended tea Oolong tea, black tea, white tea and other teas requiring uniform drying Green tea, black tea, dark tea and other teas for large-scale production
Core Advantage Flexible, precise temperature control, simple maintenance Uniform heating, good aroma locking, batch adaptation Efficient and continuous, large processing capacity, flexible energy sources

Selection Guide: Match on Demand to Precisely Lock Flavor

  1. Choose by production scale: Tray cabinets for daily output <500 kg; rotary ovens for daily output 500-2000 kg; belt dryers for daily output ≥2000 kg.
  2. Choose by tea variety: Tray cabinets for high-end handcrafted tea and small-batch multi-variety production; rotary ovens for oolong tea and black tea that need uniform aroma locking; belt dryers for mass-produced popular tea.
  3. Choose by production mode: Tray cabinets for customized, multi-batch small-batch production; rotary ovens for standardized batch production; belt dryers for automated assembly line production.
