A double-sided grinder is often a solid metal grinder with just two surfaces. But a double-sided grinder also does come with it’s benefits. One of those benefits is the ability to rapidly grind both sides of your coffee beans together. To do this, the blades on a dual-side grinder will rotate in two directions. The turning of the blades creates “real” ground coffee.
Coffee lovers who grind beans often prefer a double-sided grind that allows them the freedom to grind quickly and evenly. Some coffee purists believe that the only way to get truly authentic ground coffee is by grinding freshly grounded coffee beans right before brewing. This method allows them to make a fresh brew and to control the quality of that brew. For people who enjoy the process of grinding and brewing their own coffee, but would like the convenience of a dual-axis blade grinding machine, there are several manufacturers who have designed dual-purpose grinders that feature the two-sided action of a traditional manual grinder, but with the benefit of being able to use them simultaneously. These types of grinders are not suitable for all styles of brewing because of their fast spinning blades.
Coffee lovers who appreciate the finer grinds sometimes choose a double-sided grinder. Such machines are often designed to offer users the option to grind fine pastry and produce a light, medium or dark roasted flavor. These machines allow the user to control the intensity of the different flavors by varying the speed and duration of the grinding process. They can offer users the versatility they need to brew a wide variety of beverages from espresso to American coffee. For some, the convenience of such a machine means the choice of a larger capacity than would befit a smaller single-sided unit.
The advantage of a double-sided grinder resides in the manner in which it operates. A rotary face of varying angles rotates around a stationary workpiece in the center of the unit, similar to a burr grinder, which is in turn driven by an electric motor. A pair of rollers will move the grinding unit along the surface of the workpiece. Because the face of the unit is stationary and the rollers rotate at different speeds, the end result is a grinding result that has a more even, consistent finish than could be obtained with any other type of grinding device.
Another important factor to consider when choosing a double-sided grinder lies in the ability of the machine to work with a wide variety of different materials. Many of the most popular machines today can grind coffee, tea, chocolate and many other types of beverages. Some machines will only work with one material, while others are capable of working with a wide array of different materials. It is important to consider the amount of time that a machine is expected to be used before choosing one that will be used on a daily basis.
It should also be noted that there are two types of grinding machines today. A side Grind is used mainly for small jobs or quick precision tasks, while a top grind is often used for larger jobs requiring a finer finish. The two types of grinders differ primarily in the way they stop the grinding operation when the work piece reaches a certain level. Top grinders will abruptly stop the grinding process when the work piece reaches a specific height, whereas a side grind will gradually stop the grinding operation until the work surface is no longer able to achieve the required level of hardness.
