Question 1

What is the difference between electric and gas coffee roasters?

Accepted Answer

Gas roasters (LPG or natural gas) heat the drum with an open flame, giving fast, high heat and precise momentum control preferred by most production roasteries. Electric roasters use heating elements, are easier to install where gas lines are unavailable, run cleaner indoors, and suit smaller shops and sample roasting. Kafgar roasters support LPG, LNG, natural gas and electricity, so you can match the heat source to your facility.

Question 2

How do I choose the right coffee roaster capacity?

Accepted Answer

Match batch size to your weekly demand. As a rule of thumb, a 1.5–5 kg roaster fits cafes and micro-roasteries (up to ~50 kg/week), 10–15 kg suits growing specialty roasteries, and 30–120 kg machines are for industrial production. Remember a roaster runs best at 70–80% of its rated batch, and a roast cycle takes 10–16 minutes, so factor in cooling and loading time when sizing throughput.

Question 3

What certifications do Kafgar coffee roasters have?

Accepted Answer

All Kafgar coffee roasting machines are CE certified (European Conformity) and manufactured under ISO 9001 quality management. The machines use branded electronic components (Siemens, Schneider) and quality burners (Polidoro, Premix), and meet international export and safety standards.

Question 4

What is the best coffee roaster for a coffee shop?

Accepted Answer

For most coffee shops and boutique cafes, a 15 kg shop-type roaster offers the best balance of roast control, footprint and retail bean output. Kafgar shop-type roasters feature ST52 stainless steel drums, digital temperature control, data logging for repeatable profiles, and optional PLC control from a connected laptop or PC.

Question 5

Do Kafgar coffee roasters work with any voltage worldwide?

Accepted Answer

Yes. Every Kafgar roaster is built to order to match the customer's local power supply, whether that is 110V, 220V or 380V at 50 or 60 Hz. We manufacture each machine to your country's electrical standard, so it arrives ready to install and run without additional electrical work.

Question 6

Can I control and monitor the roast profile from a computer?

Accepted Answer

Yes. Kafgar roasters offer an optional PLC (Programmable Logic Controller) you control from a connected laptop or PC. You can monitor and adjust drum speed, airflow and gas settings from your computer, and the built-in data logger stores up to 1,000 roast records for repeatable profiles. The machines are also Artisan-software compatible.

Question 7

What warranty and support does Kafgar provide?

Accepted Answer

Kafgar coffee roasters come with a 2-year warranty. As a manufacturer exporting to over 50 countries, Kafgar provides technical support, spare parts, installation guidance and worldwide shipping with machines packaged and prepared for international delivery.

Question 8

What equipment is needed for a complete coffee roasting plant?

Accepted Answer

A complete roasting line typically combines a roaster with supporting equipment: pneumatic loaders for feeding green beans, destoners to remove foreign material, additional cooling, silos for storage, and an afterburner to neutralize smoke and odors for emission compliance. Kafgar designs, manufactures and installs turnkey roasting plants sized to your throughput, floor space and integration needs.
