Sunyoung 6CHT-80 / 6CHT-100 Dynamic Hot-Air Tea Dewatering Dryer
The Sunyoung 6CHT tumbles tea in a rotating drum through hot air for continuous first-stage dewatering, and Sunyoung says it also breaks up clumps left after rolling. The brochure lists the 6CHT-80 at ≥200 kg/h and the 6CHT-100 at ≥500 kg/h, both on a fresh-leaf handling basis, so neither figure is dry-tea output. Each model runs on wood or coal, electric heating, or gas (natural gas or LPG), and the heat source changes base power and floor layout. Wood and coal builds also need a 5 × 5 m furnace room. The sections below set out heat, power and layout, then how to test dewatering and clump breakup on your own rolled tea.

Build my procurement briefFirst-stage dewatering and what the rate means
Sunyoung presents the 6CHT for initial dehydration and says the drum also handles clump breakup after rolling. As the drum turns, tea is tossed through hot air. Drum speed, dwell time, air temperature and target moisture are not published, so describe the tea going in and what the next process needs.
The brochure states ≥200 and ≥500 kg/h as fresh-leaf handling. Those are input figures, not kilograms of dry tea or water removed per hour. If you feed rolled tea, ask Sunyoung how the rate translates for that material.
If clump breakup is part of why you are buying, describe the clumps arriving and agree how leftover clumps and leaf damage will be judged. Check both results after cooling in a full-load run. Our stage-by-stage tea machinery guide shows how drying steps are placed after rolling in a line.
6CHT heat sources and base power
Each model offers three heat sources, and base power changes with each. On electric builds the base figure is small next to the heating load. Both models list the same gas ranges, which tells you about supply rather than efficiency.
| Model and heat source | Fuel or heating figure and base power |
|---|---|
| 6CHT-80 wood/coal | 30 kg/h of fuel; base 12.11 kW. Ask what fuel grade and running condition the rate assumes. |
| 6CHT-80 electric | 135 kW heating; base 4.61 kW. Size your supply from the full electrical schedule. |
| 6CHT-80 gas | Natural gas 18–22 m³/h or LPG 16–20 kg/h; base 8.21 kW. Ask for supply pressure and the load point. |
| 6CHT-100 wood/coal | 60 kg/h of fuel; base 13.21 kW. Fuel cost per kilogram of finished tea comes from a measured run. |
| 6CHT-100 electric | 180 kW heating; base 7.21 kW. Actual energy varies with running conditions. |
| 6CHT-100 gas | Natural gas 18–22 m³/h or LPG 16–20 kg/h; base 9.31 kW. |

Straight and bent floor layouts
Sunyoung offers straight and bent arrangements. Electric and gas sizes include the furnace; wood and coal builds add a separate room. Clearances, transfer heights and connection points come from the site drawing for your order.
| 6CHT build and fuel | Floor length × width in mm |
|---|---|
| 6CHT-80 wood/coal | Straight 10800 × 1100; bent 8675 × 3360. An extra 5 × 5 m auxiliary room is needed. |
| 6CHT-80 electric | Straight 11390 × 2685; bent 12400 × 3360, furnace included. |
| 6CHT-80 gas | Straight 11130 × 3820; bent 11550 × 3360, furnace included. |
| 6CHT-100 wood/coal | Straight 11500 × 1280; bent 8675 × 3660. An extra 5 × 5 m auxiliary room is needed. |
| 6CHT-100 electric | Straight 11500 × 2760; bent 12450 × 3576, furnace included. |
| 6CHT-100 gas | Straight 11610 × 4455; bent 11500 × 3900, furnace included. |

Testing the leaf path from feed to cooler
The module includes a feed conveyor, the dynamic dewaterer, a cooling conveyor and integrated controls. Sunyoung also promises even heating, fast moisture loss, good ventilation and kept colour, without figures. Check each on your tea along the whole route.
Feed
Describe your tea and how it arrives. Ask how the feeder evens out irregular supply and what it does when supply stops.
Drum
Log the drum and heat settings and measure the tea. Ask for airflow, tea temperature and dwell time, which tumbling alone does not tell you.
Clumps
Count leftover clumps and check damage separately from moisture. Sunyoung publishes no clump-size or damage figure.
Cooling
Agree the condition the next stage needs, how it is measured and how tea transfers. Ask for cooling airflow, end point and control logic.
Published specifications
Read each value with its stated conditions, and ask the manufacturer for any limit not listed here.
| Specification | Published value | Meaning / limit |
|---|---|---|
| What it does | Continuous initial dehydration with rotating/tossing tea and hot air contact [1] | Sunyoung adds clump breakup after rolling. No final moisture, clump size or damage limit is published. |
| Models and rates | 6CHT-80 / 6CHT-100; ≥200 / ≥500 kg/h fresh-leaf handling [1] [2] [3] | Fresh-leaf handling rates. Dry output and water removed per hour are different figures to request. |
| Electric heat and base power | 80: 135 kW heat, 4.61 kW base; 100: 180 kW heat, 7.21 kW base [2] | Two separate columns. Ask for the full supply schedule of the electric build. |
| Gas consumption | Natural gas 18–22 m³/h; LPG 16–20 kg/h, both models [2] | Here each gas has its own unit. Supply pressure and gas grade still need stating. |
| Wood/coal room | Additional 5 × 5 m auxiliary room [2] | Needed on top of the machine footprint. Exhaust, clearances and service space come from the site drawing. |
Acceptance run, energy logging and documents
Fix the model and heat source, then run the tea under steady conditions. Record input and output on stated bases, the settings, and moisture, colour and clump results after cooling. A catalogue rate shows capacity; the run shows whether the tea is ready for the next step.
Log fuel and electricity in their real units during that same run. Mark the metering boundary and the time period, and keep start-up apart from steady running. Kilowatts, fuel mass and gas volume measure different things, and cost per kilogram of good tea comes from combining them over the run.
Sunyoung mentions patented technology without naming a patent. Ask for the patent details, any colour, moisture or comparison test reports, and the current component, electrical, mechanical and service documents. The photograph cannot tell you the model, materials or the full delivered package.
Buyer questions
Is ≥500 kg/h the dry-tea output of the 6CHT-100?
No. The brochure states it as fresh-leaf handling. Ask Sunyoung for dry output and water removal on their own bases. [2]
Can I size the electric 6CHT-80 supply from 4.61 kW?
No. 4.61 kW is base power; heating adds 135 kW. Request the full electrical schedule. [2]
Are natural gas and LPG listed separately?
Yes: natural gas at 18–22 m³/h and LPG at 16–20 kg/h. Confirm your supply pressure and running conditions with Sunyoung. [2]
Does the wood/coal footprint include the furnace room?
No. The brochure adds a 5 × 5 m auxiliary room to the machine footprint. [2]
Does clump breakup come with low leaf damage?
Sunyoung gives no damage or clump figures. Measure both on your rolled tea in a trial. [1]
