- 5 kg or 6 kg — How Drum Capacity Is Rated
A 6kg coffee roaster from Yoshan is the machine most cafés and micro-roasteries buy when a 1–3 kg drum can no longer keep up — and the machine most people find when they search for a 5kg coffee roaster, because we rate this class at 7 kg per batch and a 5 kg charge is where it roasts best. Three models share the size: the SD-6KG with a PID button panel for hand roasting, the YS-6KG with a Siemens touchscreen station and a choice of gas or 380 V electric heating, and the SD-6KG Pro, whose PLC runs the saved curve from charge to drop and comes with the vacuum loader in the price. All three have cast-iron drums, 1–2 minute cooling and five colours with your logo free.

Gas is the default on a 6kg coffee roaster. The YS-6KG burns LPG at 0.68 m³/h or natural gas at 1.9 m³/h and needs only a 220–240 V single-phase socket for its 1,070 W electrical load; the SD-6KG Pro runs its burner the same way on 220 V. Both are set for your gas at the factory and shipped with the regulator fitting for your country.
If you cannot run gas, both the YS-6KG and the SD-6KG Pro are built as electric roasters on a 380 V three-phase supply — the SD-6KG Pro electric is full hot-air at the same price, the YS-6KG electric is priced on request. Electric roasters this size ship without a plug and are wired to a breaker by your electrician. Tell us the country and the supply you have and the quotation states exactly which version arrives.
Prices are EXW Shenzhen: the roaster, its cooling tray and chaff cyclone, the tool kit, manual and drawing pack, film-wrapped in a fumigated wooden case; the SD-6KG Pro case also holds the vacuum loader. Your quotation lists sea freight to your port, insurance and a DDP option with duties on a separate line, and the commercial invoice, packing list and HS code go to your broker before the case does.
Every 6kg coffee roaster is built to order in your colour and gas type, so the delivery date is confirmed on the quotation rather than promised here. Payment is 50% to start production and 50% before shipment, with the test-roast video of your own machine before the balance. Warranty is one year from delivery, extendable to two years for USD 699, with parts by courier and our engineer on video.
A drum roaster is rated by the most green coffee it will hold, and it roasts most evenly with headroom above the charge. So when you search for a 5kg coffee roaster you are really looking for a drum rated a little above 5 kg that runs 5 kg batches comfortably all day — which is why we made our 5 kg class a 6 kg class: the YS-6KG and SD-6KG Pro are rated 7 kg, load 5 kg with room to spare, and still take a 7 kg batch when a big order lands.
The upgrade costs you nothing extra: the same footprint and the same budget as a 5 kg machine, and you roast more coffee per hour. If 5 kg is genuinely your ceiling, the 3.5–7 kg SD-6KG Pro roasts half batches on the same curve; if it is your floor, the 12 kg models on the YS and SD series pages are the next step.
What Is Built Into Every 6kg Coffee Roaster
Who Runs a 6kg Coffee Roaster
Four kinds of buyer order this size — and which of the three models fits each.
You roast for your own bars and a few wholesale accounts, and the 1 kg machine now runs all day. The YS-6KG roasts 1–7 kg a batch in 12–15 minutes from a Siemens screen, on a 220 V socket and a gas bottle, in the colour of your shop with your logo on the body. Add the YS-JD-Q4 filter if the exhaust cannot reach outside.
Your orders now come in 10 kg boxes and the roast has to be identical every week. The SD-6KG Pro runs a saved curve from charge to drop at 18–28 kg an hour, with the vacuum loader in the price so one person runs the shift. Cast-iron double drum, gold-plated inside, on gas or 380 V electric at the same price.
You teach roasting on a machine students will meet in a roastery, not a toy. A training centre in Kenya runs its courses on the YS-6KG: a cast-iron drum, a touchscreen that shows the whole curve, and a batch small enough that every student roasts one. The 1 kg minimum charge keeps green-coffee cost per lesson low.
You searched for a 5kg coffee roaster because 3 kg is too small and 12 kg feels too big. This is the class we built for that step: rated 7 kg, comfortable at 5, in nine photographed colours, from USD 7,499. It is the natural next step from a 3kg roaster, which then stays as the sample machine.
Looking for a 5kg Coffee Roaster? You Get 6
We do not build a drum rated at 5 kg. Every 6kg coffee roaster in our 5 kg class, the YS-6KG and the SD-6KG Pro, is rated 7 kg at no extra cost: a 5 kg charge sits well inside capacity, where a drum roasts most evenly, and you still have room for a 7 kg batch on a busy day. Same footprint, same budget, more coffee every hour.
Three Roasters, Three Levels of Automation
The SD-6KG is the hand roaster: PID button panel, gas valve and airflow under your fingers, USD 11,999. The YS-6KG is semi-automatic: you set gas, drum speed and air on a Siemens touchscreen and decide the drop, USD 7,499. The SD-6KG Pro is automatic: the PLC replays the saved curve and charges, roasts, drops and cools while you pack, USD 12,999 with the loader. Same 6kg coffee roaster class, three ways to run it.
Siemens Screen and a Cast-Iron Drum at USD 7,499
The YS-6KG puts a German-style cast-iron drum, an independent Siemens touchscreen station and a cooling tray at USD 7,499. Batches from 1 kg to 7 kg roast in 12–15 minutes on LPG or natural gas from a 220–240 V socket, and Artisan logging is available on request. It is the 6kg coffee roaster a Kenyan training centre runs its courses on.
SD-6KG Pro: Loader In, Curve Saved, One Operator
The SD-6KG Pro is the fully automatic 6kg coffee roaster: a double-layer cast-iron drum with a gold-plated inner drum, a PLC touchscreen that stores your roast and runs it again unchanged, and manual override when you want to work by hand. The vacuum loader is in the USD 12,999 price, lifting green coffee 4.5 m into the hopper, and the electric full hot-air version on 380 V costs the same.
Your Colour and Logo, Photographed Before Paint
Black, white, red, blue and yellow are standard on every 6kg coffee roaster here, and a custom colour costs nothing more. Your logo goes on both sides of the body and on the start screen of the Siemens station, and we send pre-paint photos of the frame so you approve the colour before it is sprayed. The nine colours in the gallery are photographed machines, not renders.
Test-Roasted, Crated, CE and RoHS
Your 6kg coffee roaster is run with real green coffee on our floor before it is crated, and the video reaches you before the balance is due. It leaves in a fumigated wooden case, film-wrapped and photographed, with the CE certificate under the Machinery and Low Voltage Directives (AH2023062101) and a RoHS report (AH2023062102) — copies of every certificate travel with the quotation.
Next Size Down, the Series, and the Range
Choosing a 6kg Coffee Roaster: 5 kg Loads, Gas or Electric, and What It Costs Landed
Why a 5 kg Buyer Ends Up With a 6 kg Drum
Rated capacity is the most green coffee a drum will hold, and a roast is most even with headroom above the charge. A 5kg coffee roaster that runs 5 kg batches all day is therefore a drum rated above 5 kg — which is what our YS-6KG and SD-6KG Pro are at 7 kg. Load either at 5 kg and you are in the range where heat transfer is even and the profile repeats; load 7 kg when the order needs it. That is the whole logic of the free upgrade from the 5kg coffee roaster class to the 6 kg class — and when you compare every 5kg coffee roaster for sale, compare rated capacity, not the name.
YS-6KG or SD-6KG Pro
Both have cast-iron drums, 1–2 minute cooling and a screen. The difference is who makes the decisions: on the YS-6KG you set gas, air and drum speed on the Siemens station and call the drop, which is why hands-on roasters and training centres choose it at USD 7,499. On the SD-6KG Pro the PLC runs the saved curve and the loader charges the drum, so one person can pack while it roasts at 18–28 kg an hour — USD 12,999 all in. The manual SD-6KG at USD 11,999 is for roasters who want the German-style body and a button panel.
Electric at 6 kg
Electric heating at this size means 380 V three-phase, not a wall socket: the elements draw far more than a single-phase circuit gives. Both the YS-6KG and the SD-6KG Pro are built electric on request, the Pro as full hot-air at the same price. If you only have single-phase power, gas is the practical choice — LPG from a cylinder or natural gas from the line, at 0.68 or 1.9 m³/h on the YS-6KG.
Site, Gas and Exhaust
Plan for a footprint of about 2.2 × 1.3 m for the SD-6KG Pro and 2.2 × 0.7 m for the YS-6KG, plus room to open the drum door and walk round the cooling tray; the YS-6KG weighs 600 kg, so check the floor and the doorway. You need a gas line or cylinder store, a 220–240 V socket, and an exhaust ducted to outside. Add the YS-JD-Q4 electrostatic filter for neighbours and the YS-HR12 afterburner for an inspector.
Price, Lead Time and Payment
USD 7,499, 11,999 and 12,999 are complete-machine prices EXW Shenzhen, the Pro including its loader; add-ons are USD 1,700 for the filter, 2,109 for the destoner and 5,800 for the afterburner. Every machine is built to order, so the lead time is on the quotation, with sea freight and a DDP option so you know the landed cost before the deposit. Payment is 50/50, test-roast video before the balance, one-year warranty extendable to two years for USD 699.
Our 5 kg class is the 6 kg class: we rate the YS-6KG and SD-6KG Pro at 7 kg per batch at no extra cost, so you load 5 kg with room to spare and still have capacity for 7 kg. There is no separate 5 kg drum — you get the bigger one at no extra cost.
Yes, on 380 V three-phase power. The SD-6KG Pro electric is full hot-air at the same USD 12,999; the YS-6KG electric is priced on request. On single-phase 220–240 V the 6kg gas coffee roaster runs on LPG or natural gas, with the YS-6KG drawing 1,070 W.
Yes. USD 12,999 covers the roaster, the vacuum green-bean loader that lifts coffee up to 4.5 m into the hopper, the cooling tray, chaff cyclone, tool kit, manual and drawing pack. Destoner, smoke filter and afterburner are quoted separately.
The SD-6KG Pro is rated at 18–28 kg of roasted coffee an hour on 3.5–7 kg batches of 8–15 minutes. The YS-6KG roasts 1–7 kg batches in 12–15 minutes; its hourly output depends on your profile and charge, and we quote it for your roast level rather than print one number.
Buy 6 kg if a 3 kg machine would run more than a few hours a day: at 5–7 kg a batch you roast a week of café coffee in an afternoon and keep a 3 kg or 1 kg as the sample machine. Buy 3 kg if a few batches a day cover your orders and you want the lower price and footprint.
Both the drum exhaust and the cooling-tray exhaust must reach outside. In a shop or a residential street add the YS-JD-Q4 electrostatic filter (USD 1,700), and where an inspector requires it fit the YS-HR12 afterburner (USD 5,800), which burns off smoke and odour before the flue.
Every one is built to order in your colour and gas type, so the date is confirmed on your quotation. Payment is 50% to start and 50% before shipment by bank transfer, with the test-roast video of your machine before the balance; sea freight and a DDP option are on the quotation.
One year from delivery on the machine, with parts sent by courier and our engineer on video for anything the manual does not cover. You can extend it to two years for USD 699 at order. The tool kit, manual and drawing pack ship in the case.
