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.

Handling and Maintenance

Yes, tech support is available and can be reached during our business hours.
If you are seeing an air failure, you’ll want to start by cleaning the roaster and ducting, scraping down to the metal, and checking the vacuum sensor tube, This tube senses airflow through the roaster. Use a small tool to clean out any debris to clear the tube. DO NOT put a vacuum on it or blow compressed air through it. We will also want to ensure that the blower shroud and internal roaster pipes (back exhaust elbow) are all in place and doors are shut tightly.
No, you can't. You must store /put your roaster in a standing position.

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.
