Blade Grinder - Why You Shouldn't Use One

Blade grinders use a propeller-like blade (think blenders) to chop coffee beans. They are less expensive than burr grinders and easy to clean, but they do not produce uniform grounds and can cause over-extraction and bitterness in your coffee.

A top-quality coffee experience requires uniform distribution of the particles, something that is only possible with a burr grinder. This is the reason why coffee lovers hate burr grinders.

Inconsistent Grinds

If you've used a blade grinder for a while it is likely that your grinding results have been inconsistent. The machine is likely to be worn out and dull. As the grinder wears out, it will chop up beans into various sizes. This will produce grounds with varying levels of coarseness. It's challenging for your coffee maker to extract the same, balanced taste with these various-sized particles.

Blade grinders use the same propeller-like blade to break beans. It cuts the beans into smaller and smaller pieces, which are then tossed into a catcher through the screen. Although this method is effective, it's not ideal to get the perfect grind for your brew. A better option is the burr grinder. A burr grinder comes with an efficient motor with two grinding burrs, and is a larger machine. The burrs can be set at a certain distance apart which determines the quality of the coffee being ground.

If the burrs are too close to each other, they'll crush the beans, rather than cutting them. The result is a finer more refined, less coarse ground. They are also more brittle, which can negatively impact the taste of your coffee. If the burrs on the other hand are not evenly spaced they'll result in large chunks of coffee that have been coarsely ground. It's crucial to choose a espresso coffee grinder grinder that has an appropriate setting to match the level of coarseness you want.

A sharp, properly adjusted blade will result in a consistent and fine grind for your coffee. If you notice that your grind is becoming more uneven, it's probably best to replace the blade or burrs. If you haven't yet done so, you must also alter the grind setting to get more even grinding.

It's also important to note that if your grinder creates ground that is clumpy, this is an indication of worn or damaged blades. The clumping occurs due to small particles adhering to each other and larger pieces of grounds making larger granules that do not dissolve well in water. As your burrs grow and dull this will occur more often.

Uneven Extraction

Whether you're brewing drip, French press, or pour-over the size of your grounds plays an crucial role in preserving flavor. Uneven ground sizes can lead to uneven extraction and a sloppy cup of coffee.

As the beans move through a blade grinder they are cut and shredded indiscriminately resulting in an uneven distribution of the grind particle sizes. A blade grinder may produce an assortment of large fragments as well as dust-sized particles and everything else in between. Different grind sizes produce at different rates, resulting in an inconsistent and often bitter cup of coffee.

In addition, the lack of uniformity results in problems with filtering and tamping. With a burr grinder, you can get an even particle size, allowing for more uniform tamping and filtering, which helps prevent over-extraction and weak beers. It is difficult to achieve an equal grind with a blade grinder. You may have to tamp from side to side, or employ the Stockfleth Method (which requires some practice).

Another problem with blade grinders is their high speed and heat generation. This can burn the grounds and create a bitter taste. Burr grinders generate less heat and are cooler, thus preserving the flavor of the beans.

A final downside of a blade grinder is that it's very easy to over-grind your beans. Running the grinder continuously produces a lot of heat, and eventually causes your grounds to become over-extracted, resulting in bitter brew. To avoid this, pause your grinder before turning it back on.

Blade grinders have many advantages, such as their low price and speedy operation. However, they also have some drawbacks for instance, the fact that they produce heat when they are in use and produce different grind sizes, and lack control over the final particle size. With a little bit of practice however, there are ways to improve results despite the inherent limitations of this kind of grinder.

When paired with a burr grinder, the user can easily adjust the gap between the grinding discs to fine-tune the exact size of ground of their preference.

An angle grinder is an extremely powerful tool that should only be used only by trained personnel. It can cause grinding burn when used incorrectly. This causes localized changes to the metallographic surface of the workpiece. This can cause cracks that, if left unchecked, can eventually result in macropitting and tooth fracture.

Grinding burns can be caused by a variety of factors, including excessive grinding pressure or insufficient cooling. It can be caused by inadequate training for operators. Wear the proper safety equipment when using an angle grinder. This includes safety glasses, a face shield and steel toe boots. This will prevent sparks of heat from flying off the wheel and hitting equipment or people near by. Sparks can be capable of reaching temperatures as high 3,600 degrees Fahrenheit, and they can cause damage to materials such as paint or even metal.

Brew that is disappointing

The unevenly sized grounds extract at different rates in your coffee maker, which can result in an unpalatable or weak cup of brew.
