Tea processing
Sunyoung 6CS Tea Conveyors and 44T / 100T Elevators
Sunyoung builds five kinds of tea conveyor to link processing machines: cleated belts (6CS25B, 45B, 60B), inclined elevators (44T, 100T), level belts (6CS25P to 90P), mesh-belt cooling elevators (6CS50W, 60W) and vibrating conveyors (6CS28Z, 33Z, 50Z). Besides moving leaf, they feed and balance flow between stages. The brochure gives belt speeds, motor power and hourly rates from ≥80 to ≥300 kg/h, plus a shared tea-leakage limit of ≤5.0%. Start by describing the machine the leaf leaves and the machine that receives it, then pick the form, the extras and the cooling duty.

Build my procurement briefDescribe the handoff between your two machines first
The right conveyor depends on the gap it bridges. Sunyoung covers level runs and runs between heights, with feeding and flow balancing on top. Inlet and outlet drawings are not published per code, so give Sunyoung the details of both ends before looking at rates. The machines at either end may be the maker's own, such as the 6CSF hot-air tea fixation module or the 6CHB continuous tea dryers.
Where leaf leaves
Note the upstream machine's discharge point, height, direction and the state of the leaf. Say whether discharge is steady, in batches or stop-start.
Where leaf arrives
Name the next machine's inlet, the feed pattern it wants and the delivery limits it can take. A conveying rate on paper says nothing about how evenly leaf lands.
Route and access
Give the height difference, the space available and any access limits. Ask for an arrangement drawing with lengths, belt or trough widths and supports; the figures in a code are not dimensions.
Stops and starts
State the flow you need through the linked machines. Ask how the chosen conveyor reacts when the upstream or downstream machine stops, since no line sequence is published.
The five conveyor types and their brochure values
Each row is a different way of moving leaf. A vibrating conveyor's higher rate does not make it a stand-in for an elevator, and a cooling conveyor does a process job that a plain belt does not. The photographs show inclined leaf transfer in general rather than a particular code.
| Form and codes | Published values and what to ask |
|---|---|
| Cleated belt: 6CS25B, 45B, 60B | Speed 0.11–0.18 m/s; rate ≥80 kg/h. Power shares one cell with the elevator at 0.55–1.1 kW. Confirm geometry and the motor fitted. |
| Inclined elevator: 44T, 100T | Speed 0.17–0.37 m/s; rate ≥120 kg/h; same 0.55–1.1 kW cell. Height, slope and leaf retention are not printed. |
| Level belt: 6CS25P, 30P, 40P, 50P, 90P | Speed 0.15–0.40 m/s; power 0.55–1.5 kW; rate ≥120 kg/h. Length, width and the exact build come from the quote. |
| Mesh-belt cooling elevator: 6CS50W, 6CS60W | Speed 0–1.10 with no unit in the cell; power 0.55, unit missing; rates ≥150 and ≥300 kg/h, not matched to codes. No cooling conditions are given. |
| Vibrating: 6CS28Z, 33Z, 50Z | Speed shown as a slash, meaning no value; power 0.55, unit missing; rate ≥200 kg/h. Ask for vibration amplitude, frequency and feed setting range. |
Published specifications
Read each value with its stated conditions, and ask the manufacturer for any limit not listed here.
| Specification | Published value | Meaning / limit |
|---|---|---|
| Conveyor forms | Cleated belt, inclined elevator, level belt, mesh-belt cooling/elevation, vibrating [1] [2] | All five appear in the brochure. The product page groups them as belt or vibrating-trough types for level or rising transfers. |
| Brochure codes | 6CS25B/45B/60B; 44T/100T; 6CS25P/30P/40P/50P/90P; 6CS50W/60W; 6CS28Z/33Z/50Z [2] | Order shorthand only. Length, width and materials come from the arrangement drawing for your route. |
| Motor power | Cleated/elevator shared 0.55–1.1 kW; level belt 0.55–1.5 kW; cooling/vibrating 0.55, unit not explicit in those cells [2] | Ranges cover a whole form, not a single code. Ask which motor comes on the conveyor you order. |
| Hourly rates | Cleated ≥80 kg/h; elevator/level ≥120 kg/h; cooling ≥150 and ≥300 kg/h; vibrating ≥200 kg/h [2] | Printed without leaf condition, length, slope or loading. The two cooling rates are not tied to a specific code. |
| Tea leakage | ≤5.0%, printed in a merged cell [2] | Covers leaf escaping from the conveyor. Breakage, overall yield and hygiene are separate questions, and no test method is given. |
| Optional devices | Even-feed, cleaning, speed adjustment and dust-related devices [1] | Added as needed, per the product page. Name the ones you want in the offer. |
Belt speed, leaf loading and flow balancing
Belt rows give travel speed; the vibrating row does not. Travel speed tells you how fast the belt moves, not how much leaf sits on each metre or how it enters and leaves. Layer depth, loading density and usable length are not published, so kilograms per hour cannot be worked out from speed.
Sunyoung says its conveyors help control capacity and balance flow between main machines. To get that, describe your feed pattern and what the next machine needs. Ask how the drive and any metering or even-feed device adjust delivery, what signal triggers a change, and what happens when leaf piles up or stops coming. Put those functions in the agreed control description; an adjustable drive alone does not deliver them.
The hourly figures name no fresh or dry condition, tea form, incline or loading. Ask for a conveying test with your leaf on your route, and watch the handoff as closely as the rate. A high rate is of little use if the next machine cannot take the leaf as it arrives. Matching capacities between stages is the line-sizing topic in our tea processing machinery by stage guide.
Leaf leakage, cleaning and dust control
The brochure's shared loss cell is labelled tea escaping or leaking rate and reads ≤5.0%. It gives no sample size, run time, collection method or leaf basis. It is a leakage figure, so it says nothing about breakage and cannot be turned into a 95% process yield. Ask Sunyoung how the figure was measured.
On your route, mark where leaf could be held back, escape or spill: at the inlet, along the belt or trough, and at the receiving point. Agree how recovered leaf and true losses will be counted in the test run. If leaf damage matters to you, score it separately against your processor's criteria.
Sunyoung says cleaning and dust devices can be added as needed and describes a cleaner production route kept off the floor. Food-contact grade, cleaning method, dust rating and hygiene certificates are not published. Ask for the belt and trough materials, cleaning access and the exact optional devices for your order.
Cooling duty and what to check at acceptance
A cooling conveyor is its own selection. Sunyoung lists a mesh-belt elevating cooler but no airflow, end temperature or residence time, and the two cooling rates do not tell you the leaf's final state. Test cooling with your leaf and have Sunyoung define what the offer covers. Where cooling is paired with wind selection, the maker's 6CEF-40H module combines the two jobs.
| Part of the conveying system | What to specify and check |
|---|---|
| Cooling target | Describe the leaf coming in and the state the next machine needs. Ask for the cooling method and settings of the selected build; no fan airflow or cooling time is published. |
| Optional devices | List each even-feed, cleaning, variable-speed or dust device you need, with quantities, control links and who supplies what. |
| Mechanical and electrical joints | Approve inlet and outlet positions, supports, access and drive controls with the connected machines. Get the missing power and speed units and the exact motor in writing. |
| Acceptance run | Use your leaf, route and feed conditions. Check delivery control, leakage, leaf damage where relevant and the cooling result, then sign off documents and service terms. |
Buyer questions
Is ≤5.0% the maximum tea breakage?
No. The cell covers tea escaping or leaking, with no test conditions. Breakage and overall yield need their own measurement. [2]
Is the cooling speed 0–1.10 in m/s?
The belt rows say m/s, but the cooling cell has no unit. Ask Sunyoung to state the unit and the drive specification. [2]
Does the slash in the vibrating row mean zero speed?
No. The belt-speed field is simply empty for that form. Ask for the vibration frequency, amplitude and setting range. [2]
Do all conveyors come with cleaning and dust devices?
Sunyoung adds them as needed. List the devices you want so they appear in the agreed package. [1]
What leaf condition do the ≥150 and ≥300 kg/h cooling rates assume?
None is given: no end temperature, airflow or time, and neither rate is tied to a code. Ask Sunyoung to define the cooling duty for your order. [2]
