Coffee Roaster Case Study: A Custom White YS-6 Line for a Roastery in Oman

The Brief: One Brand, One Line, One Supplier

The roastery serves cafes and retail customers around Muscat, and three requirements — you may recognise your own — pushed them to a factory build rather than an off-the-shelf import:

• Brand identity from day one. The roaster in a custom white finish with their logo — not a generic machine to re-badge later.
• LPG, not natural gas. No reliable mains gas at their unit, so the burner had to leave the factory jetted for bottled LPG at Gulf supply pressure.
• Retail packaging in-house. They planned to sell bagged coffee, so they needed a filling machine and a sealer matched to their bag and throughput — shipped with the roaster so everything arrived as one commissioned line.

Why the YS-6

We recommended the 6 kg YS-6 from the Siemens-PLC YS series. At 6 kg it is the sweet spot for a launching roastery: large enough to supply several wholesale accounts and a retail line, small enough to dial in your single origins and keep your green inventory manageable. The PLC gave them saved, repeatable profiles from the first week — which matters when you are not the only person roasting.

What We Customised for the Gulf

Colour and logo. Applied at the factory, logo on the front panel. Custom finish adds lead time but no import complication for you — the machine clears customs already branded. It is the same path most of our Gulf and Latin American clients take, and the one you would take; the OEM and ODM guide explains what can change.

LPG. Burner, jets and regulator set for bottled LPG at Gulf pressure, with the gas connection documented so a local technician could connect it safely. Switching between natural gas and LPG is not a hose change — the orifices differ — which is why we set it before shipping rather than leaving it to your technician.

Voltage and frequency. Controls and motors set to the local supply, confirmed on the order so nothing needed a converter on arrival.

Packaging match. Because the filler and sealer were specified with the roaster, bag size, fill weight and seal type were matched to their retail plan — as they would be to yours — no mismatched second-hand gear after launch. The packaging guide has the sizing logic.

Shipping and Commissioning

The line shipped by sea to a Gulf port as one consolidated order — one packing list, one set of documents, one clearance. We supplied installation drawings, the LPG connection guide and remote commissioning on video, so the client's local technician positioned the roaster, connected gas and power, and ran the first test batch with our engineer on the call. The Gulf guide covers the regional gates — SABER, 60 Hz where it applies, LPG — and the commissioning guide the week after delivery.

What You Can Take From This

• Buy the line, not the machine. Roaster, loader and packaging from one factory means matched voltage, matched gas, one shipment and one point of contact for spares. The equipment list shows what belongs in a first container.
• Specify LPG up front. If your site runs on cylinders, say so at the quote so your burner ships jetted for it.
• Custom colour is worth the lead time. A branded machine builds your identity from launch, and it clears customs as it is.
• Plan your utilities for the line. Their power, floor space and duct were sized for the whole line, so nothing was rebuilt when the packaging arrived — do the same before your lease.

What the Same Line Costs

If you want the same line, every price here is our factory price, ex-works, from the current list:

Freight to Sohar, Jeddah or Jebel Ali, SABER or local conformity, duty and installation are your own lines; the price guide lists every model and the shipping guide the landed-cost sequence.

Frequently Asked Questions

Can I see the Oman roastery or speak to the owner?

We keep client identities private unless they choose to be named, so we do not pass on contact details. What we can share is the build file for a line like theirs — the drawings, the packing photos, the commissioning video with faces and logos removed — and we can put you on a video call with our engineers on the test bench with a machine in your colour before it ships.

How long does a custom colour and logo add?

The finishing is done after the machine is built and tested, so plan on extra weeks beyond a standard build, and get the figure on the quote. Send the colour reference (RAL or Pantone) and a vector logo file with the order; changes after painting cost time. On the DY series colour and logo are included at no charge; on YS and SD they are quoted with the machine.

How do I choose the filling and sealing machines?

From the bag, not the roaster: tell us the bag size, the fill weight, whether it has a one-way valve, and how many bags a week. Under about 300 bags a week a semi-automatic filler and a band sealer are enough; above that an auger filler with a date coder. We size the pair to the roaster's output so the packing bench keeps up with the drum.

Would a 12 kg have been the better choice?

Not for a launching roastery selling to a handful of cafes and its own counter. A 6 kg at 60–80% load gives 18–28 kg of green an hour — enough for 150 kg or more a week — while keeping green inventory and practice batches small. The step to a YS-12 at USD 9,980 is one to make when the accounts exist, and the saved profiles move with you.

Do you ship the same line to Saudi Arabia and the UAE?

Yes — the build is the same, and only the conformity document changes: SABER for Saudi Arabia, the ESMA/ECAS route for the UAE, GSO-based schemes elsewhere in the Gulf. We supply the technical file the certificate needs and your importer of record applies; start it when the machine goes into production, because the certificate must be in place before the ship arrives.

Final Thoughts

This coffee roaster case study is really one lesson: think in lines, not machines. The Oman roastery ordered a YS-6 and shipped a roaster, a loader, a filler and a sealer built for their gas, their power and their brand — and opened on one delivery.
