Blade Grinder - Why You Shouldn't Use One

Blade espresso grinders are equipped with blades that look like propellers (think blenders). They are used to chop coffee beans. They are cheaper than burr grinders, and are easy to clean, but they do not produce uniform grounds and can cause excessive extraction and bitterness in your brew.

A premium coffee experience requires uniform distribution of particles, something that can only be achieved by using the burr grinder. This is the reason why stainless steel coffee grinder electric snobs loathe burr grinders.

Inconsistent Grinds

You may have noticed that your grinding results are inconsistent when you've been using a blade grinder for a long time. The machine is likely to wear out and dull. As the grinder gets older it will produce different-sized pieces of beans. This produces grounds with varying degrees of coarseness. It's a challenge for your coffee brewer to extract the same, balanced taste with these various-sized particles.

A blade grinder cuts beans by rotating a blade that appears like propellers. It basically chops the beans into smaller and smaller pieces, which are then dropped through a screen and into the catcher. Although this method is effective, it's not ideal to get the perfect grind for your brew. An alternative is the burr grinder. A burr grinder is a larger machine with a powerful motor and two grinding burrs. The burrs are set to an exact distance from one another and this determines the degree of coarseness of your ground coffee.

If the burrs are too close, they will smash rather than cut beans. The result is a finer, less coarse ground. They are also more soft, which can adversely affect the taste of your coffee. If the burrs, on the other hand are too far apart they'll result in large chunks of coarsely ground coffee machine with grinder. It is essential to choose the grinder with a setting that corresponds to the coarseness you want.

A sharp, well-adjusted blade will result in a consistent and fine grind for your coffee. If you notice that your grind is becoming more uneven, it may be time to replace the burrs or the blade. You should also consider changing the grind setting if you haven't previously in order to help you achieve an even and consistent grind.

If your grinder is producing clumped-up grounds it could be an indication that the blades have worn out or damaged. The clumping happens due to tiny particles bonded to each other and larger pieces of grounds making larger granules that don't dissolve well in water. This is more frequent as your burrs become duller.

Uneven Extraction

The size of your coffee grounds is vital to extract flavor, whether you're using a French press pour-over, drip or drip brew. Uneven ground sizes lead to uneven extraction and a sloppy cup of coffee.

The beans are cut and shred indiscriminately as they move through the blade mill, resulting in an unbalanced distribution of the size of the grind particles. A blade grinder produces smaller fragments, small particles, and everything between. Different grind sizes are extracted at different rates, leading to an inconsistent and often bitter cup of coffee.

Inconsistency can result in problems with tamping and filtration. With a burr grinder, you can get an evenly ground particle size, allowing for more even tamping and filtering, which helps prevent over-extraction and weak brews. It is more difficult to achieve a consistent grind using a blade grinder. You may need to stamp from side to side, or use the Stockfleth Method (which requires some practice).

Another problem with blade grinders is their high speed and high heat generation. This can cause the ground to get burned and produce a bitter taste. Burr grinders generate less heat and are cooler, which preserves the flavor of the beans.

The blade grinder has one final disadvantage: it's easy to grind your beans to a fine. The grinder can generate a lot heat and your beans will eventually be pushed to the limit. This will result in a bitter brew. To avoid this, always stop the grinder prior to switching it back on.

Using a blade grinder is an efficient and inexpensive way to grind your coffee at home, but it's not the best option for those who are serious about their coffee brewing.

These charred particles aren't good for the brewing process and will create an unpleasant taste in your coffee.

A premium coffee experience demands uniform distribution of the particles for the best burr grinder flavor extraction during the brewing process. Since a blade grinder breaks up the beans into different sized pieces, small and large it is difficult to achieve this level of consistency. A burr mill, however produces a uniform distribution of particles sizes that can be reproduced across a variety of beverages.

While the benefits of a blade grinder include its low price and fast execution, its main disadvantages are that it creates heat when it is used, creates inconsistencies in grind size, and is not able to control the final particle size. There are ways to increase the efficiency with this type of grinder despite its inherent limitations.

When a burr mill, the user is able to easily alter their desired ground size by adjusting the gap between the discs. This allows them to extract all of the desired flavors from their favorite beans each time. It takes a lot of practice to create a quality beverage using a blade grinder.

Angle grinders are a powerful tool that should only be employed by professionals. It could cause grinding burn if it is used improperly. This causes localized changes to the surface of the metallographic material. This can cause cracking, which is not properly checked, could lead to macropitting and tooth fracture.

Grinding burn is a major issue that can be caused by a variety of factors including excessive grinding pressure, inadequate cooling or inadequate operator training. If you intend to use an angle grinder, make sure to wear the proper PPE including gloves with a face shield safety glasses, stainless steel coffee grinder toe boots and long sleeves. This will stop any hot sparks from flying off the wheel and hitting equipment or people near by. Sparks can be capable of reaching temperatures up to 3,600 degF and burn through materials like paint or even metal.

Brew that is disappointing

A blade grinder chops up your beans randomly, leaving you with grounds that vary in size. The uneven ground extracts coffee at different rates, which results in the cup being bitter or weak of coffee. The issue is that it ruins the balance that makes for a great cup of coffee grinder.

The blade is activated by pressing the button. It then chops your coffee beans into different sized pieces. The small pieces fall to the bottom of the chamber, and are chopped again, while the larger pieces remain at the top. This results in uneven grounds which are difficult to measure.

Another issue with these grinders is that they produce plenty of heat as they grind, which could damage your beans and ruin the coffee you drink. The heat also takes away some of the flavor of your beans, so you're left with a bland cup of coffee.
