What are the benefits of hot air roasting?

Hot air roasting, particularly indirect systems, provides a very even heat transfer to the coffee beans, which can result in a cleaner, more consistent roast profile and reduced scorching.

Is this type of roaster suitable for different coffee types?

Yes, hot air roasters are highly versatile and can be used for a wide range of coffee beans, from light roasts for filter coffee to darker roasts suitable for espresso.

What maintenance is typically required for a roaster of this size?

Regular maintenance includes cleaning the drum, cyclone, and exhaust system, checking burner components, and inspecting moving parts. Specific schedules should be followed as per the manufacturer's guidelines.

Can this roaster be converted to natural gas?

Many gas-fired roasters can be converted between propane and natural gas, but this requires professional modification by a qualified technician to ensure safety and optimal performance. Buyers should confirm this with the seller.

What are the typical ventilation requirements?

Roasters require robust ventilation for exhaust gases and chaff. This typically involves a dedicated flue system and often a separate cooling fan and exhaust for the roasted beans.

Petroncini T30 – 30Kg Hot Air Coffee Roaster Manufactured in 1995. Comes complete with Green bean loader and Cyclone. It runs on Propane Gas with indirect heat, via a Hot air chamber beneath the drum. The Hot Air is transferred into the drum creating an even roast at approx. 3.5 roasts per hour. It's ideal for Espresso Coffee. It was originally purchased by the previous owners in 1995 where it ran very successfully in New Zealand until 2010. It was then professionally shipped over to the UK and was running again very successfully in a Speciality Coffee Roastery in London until 2016, when it was replaced with a larger capacity roaster. First photo shows it when it was previously installed in London in 2016/17 and the rest of it now in storage. It is now in storage in the UK awaiting sale.
