We are proud to be the first Czech producers of coffee roasters!

A big challenge for us was the design and subsequent production of a coffee roaster. The coffee roaster can hold up to 3 kg of green coffee in one cycle, which it roasts in about 20 minutes, this time varies depending on the type of coffee. Three heating elements with a total output of 9 kW take care of roasting. Programmable thermostats ensure a stable temperature during roasting. Thanks to the frequency converters, the speed of the drum and the speed of the exhaust fan can be regulated. Thanks to the cyclone, the coffee chaff goes into a special basket during roasting. The roaster is also equipped with a so-called tasting paddle, with which an experienced barista checks the roasting process. After finishing roasting, it is very important to cool the coffee down as quickly as possible so that the roasting process is finished and the coffee retains its qualities. A drum is used for rapid cooling, in which the roasted coffee is mixed and at the same time a powerful exhaust fan starts to pump out the hot air.

"In an effort to find a suitable roaster machine for our roaster, we went through quite a large selection, but with each of them we came across restrictions or limits that would significantly limit us when roasting coffee and maintaining the roaster itself. With this challenge, we approached the mechanical engineering office Kizek, which was able to provide us with a complete service related to the development and production of a roaster exactly according to our specific requirements. In addition, the Kizek company brought its design and technological know-how to the process, enabling the creation of a compact and unique coffee roaster. Through this new roaster, we are able to achieve absolutely exceptional pure coffee flavors that would otherwise be impossible to achieve. Important maintenance and ensuring the hygiene of the roaster is very easy and time-saving thanks to the materials used and easy access to all parts."
