For Danish Gas Roaster uses high-quality casted iron, while for Deco Industrial hot air roaster uses perforated stainless steel material.

For the main controller, we build our own controller under the Hartanzah brand, and for the electric accessories (contactors, power plugs, etc.), we use a mix of Schneider, Siemens, and other common electric component brands.

For the Danish series for a capacity of 1 kg to 5 kg, we use an atmospheric jet burner and for the Danish series for a capacity of 10 kg to 25 kg, we use a premixed burner. The BTU output varies according to the size of the roaster. You can find the detailed BTU/KW rating of each burner in our catalog.

The Danish Series for a capacity of 10 kg to 25 kg uses a gas-modulating premixed burner, which allows for modulating operation at a rate of 1:4. The burners are equipped with air-fuel ratio control gas trains.

The air pressure can be adjusted above 200 Pa. Higher operating pressure increases airflow from the roaster fan, enhancing convection heat for the coffee beans. Conversely, a lower Pa setting allows for more conductive heat during roasting.

Yes, the Hartanzah roaster can roast a true max batch. However, batch capacity and roast capacity per hour depend on the type and quality of green coffee, the degree of roast, and the moisture content of the beans.

Hartanzah roasters are designed and built for roasting specialty coffee. Its design is based upon a higher ratio of conductive over convective energy supply to the beans when compared to other conventional roasters on the market. This allows you to roast each variety and origin to its optimum quality and flavor profile.

Approx 98%. For routine monthly maintenance, it is necessary to clean the bearings and lubricate them (the main bearing is located at the front of the drum, and the secondary bearing is at the back of the drum). In addition to bearing cleaning, it is also necessary to clean the pipes from the residue of roasted coffee. This cleaning is generally done for 3 to 5 hours, depending on the size of the roaster. If the roaster is used for 8 hours a day for 30 days, then the total operational hours of the machine = 240 hours per month - 5 hours = 235 / 240 x 100 = ~98%.

The roaster machine's components that need to be replaced are bearings. These bearings require special attention, and regular cleaning and lubricating is required according to the specified schedule. If these bearings are consistently cleaned and lubricated, they are typically replaced every 3 to 4 years.
