The prices of beverage roaster designs are known to vary with their sizes; they can cost as little as a few hundreds to hundreds of thousands. The price of the product though does not always correlate with quality offered thus some roaster designs offer some good services regardless of their prices being relatively low. Denver coffee roasters range from basic stove top models to the ones that entirely automatic but the functionality still remains the same.
Just below the range is the basic top models, they are composed a saucepan which has a tight lid that has a special handle that allows the beans to pass through the crank as the process move along. Constantly stirring the beans helps in maintain a constant temperature circulation and also helps the beans from roasting at the bottom of the roaster.
The high end automated roaster is designed to be easily operated, when the beans are measured and poured into the roaster, one has to wait for just a few minutes before checking the results. In built thermometers and rotating canisters are used to regulate the temperature and rotation while ensuring that the beans are not over heated or overcooked.
Air roaster designs, known for the use of air, are the most used type of roaster, they use the same mechanism used by the pop-corn maker in which heated air is circulated in the mixture while beans rotate around with the canisters helping by rotating them from where they are fitted, normally at the bottom of the roaster. The roast is normally uniform.
The ability of the roaster to circulate air evenly over the beans is one major consideration when purchasing the roaster; the beans have to be roasted uniformly if the roaster has to produce quality coffee. Roasters with a single burner at the bottom do not regulate the heat due to the air constriction thus the roast is uneven.
A hybrid of the roaster designs will be the drum roaster which has a rotating drum and it eliminates the possibility of uneven roast completely. This can be explained by the idea of using gravity force to move the beans in a circular manner around the burner. The see-through glass insert installed in the machines allows monitoring of the entire process.
In fine tuning and experimentation the see-through glass will come in very handy and helpful, in case the machine is facing some difficulty it will be very easy to tell and rectify the problem before it escalates to something that would need costly repairs. They also have preset amounts on dial to help in setting from dark to light; some are more sophisticated to have filters to filter out the chaff produced as the skins burst while the bean is expanding.
Evolution as seen the roaster designs grow from being used commercially only to being incorporated in the house-hold setting to produce quality coffee in small amounts too. The advantage of using roasters is not eliminated regardless of the setting that the roaster is used thus the large amounts can still be processed.
