The coffee mill is in fact just as important for the quality of espresso as the espresso machine itself. In home brewing this is the place that most often suffers from false economising. Coffee powder for the preparation of espresso should have a particle size in the range 0.3 – 0.4 mm (ordinary filter coffee: 0.4 – 0.6 mm), although the ...
In an open loop system, the input is directly applied to the system through a controller and output known as controlled output is obtained. In this case, the input to the controller or the control action is no way affected by the value of controlled output i.e. the output is neither measured nor feedback for comparison with the input.
Whether by machines or humans, coffee is always harvested by one of the following two methods: Strip picking – The cherries are stripped off of the branch, either by hand or by machine. Selective picking – The red cherries are picked and the green ones are left to ripen. Picking is carried out at 10 day intervals.
although other varieties have been developed. The average arabica coffee plant is a massive bush with dark-green oval leaves. The fruits are also oval and contain two flat seeds. Arabica coffee represents about 70% of total world production. Robusta coffee (Coffea canephora) produces beans which are generally blended

Robusta coffee is native to Uganda, giving researchers an advantage in breeding new varieties with high productivity suited to the changing climatic conditions and with higher resistance to pests and diseases. Disease resistant varieties (e.g. Coffee Wilt Disease) and technologies to control pests (e.g. Black Coffee Twig Borer) are available.
Coffee is an important crop with more than seven million tons of green beans produced every year. After oil, coffee ranks second in international trade exchanges. The two main species cultivated throughout the tropical world are Coffea arabica and Coffea canephora, which represent 70 and 30 %, respectively in world production.
