The Hottop Roaster is a high-quality, stable and well-thought-out roaster for the home. It is a drum roaster; i.e. the beans are constantly moved in the drum so that they roast evenly. You can control the temperature inside the drum, and control the air supply, thus influencing the roasting curve. Due to the bean throw-in at the top of the roaster, you can preheat the machine very precisely to the starting temperature and thus obtain a very accurate and consistent roasting curve. In addition, the Hottop Roaster has a built-in cooling device, like the large commercial roasting machines. Cooling is essential to complete the roasting process at the time you want and at exactly the degree of roasting you want. Through the window you can judge the beans very well with the eye, and both the first and the second crackle are easy to hear.
The model with PC connection (KN-8828B-2K+) gives you full control. You can control the roasting directly during the roasting process by adjusting the temperature supply and the ventilation yourself, either directly on the unit or via the Artisan software program on the PC. This gives you flexibility during roasting and allows you to influence the curve immediately. You can also have the roaster controlled automatically via a PC control or via the so-called alarm function in Artisan directly from the PC.
You can save the roasting curves to your PC using the Artisan software and add information such as the cupping/taste profile as well as notes on bean type, stinging, and so on. For experienced roasters, important parameters such as the "Rate of Rise" or the "Roast Development Time %" are calculated and documented live.
The roaster also allows you to familiarize yourself with the Artisan software, which many commercial roasters use on the large roasters. You can even transfer the curves you’ve developed to a "production roaster", which is cost-effective, as you can work out the ideal roasting curve with small quantities.
As with all Hottop models, you can get started quite simply because it already has an automatic program pre-stored in the roaster, which roasts very good coffee – you only have to decide when you want to finish roasting (in other words, how light or dark you want your coffee).
