Coffee is a natural product. Harvested in the coffee plantations of countries like Brazil, Colombia, India or Africa, the green coffee beans travel a long way before they end up in your coffee roaster. These are the green beans that you use to roast the finest coffee for your customers and it is important that they are fresh and clean.
Foreign bodies in coffee
As all natural and imported products, also coffee beans contain a small percentage of foreign bodies, or ‘sticks and stones’ in other words. It doesn’t really matter which quality you use, as this will always be part of the product. However, you do not want these parts to be present in the end product. Whether your end product is ground coffee or roasted coffee beans, it is important that it is 100% pure.
How to destone coffee beans
If you want to produce roasted coffee of the finest quality you will always need to destone the material as part of the coffee roasting process. The standard process is that you first roast the green beans in the way you are used to and according to your standard, professional settings. When the beans are roasted they first need to cool down, using the cooling tray and fan of the Giesen Coffee Roaster. This is also a standard step in the roasting process.
