Blade Grinder - Why You Shouldn't Use One

A blade grinder employs propeller-like blades (think blenders) to chop coffee beans. They are less expensive than burr grinders and easy to clean but do not produce uniform grounds and can lead to over-extraction and bitterness in your coffee.

To get the best coffee experience, you need uniform particle distribution. This can only be achieved by using a burr mill. This is the reason why coffee lovers hate them.

Inconsistent Grinds

If you've used a grinder with a blade for some time there's a good chance that your grinding results have been inconsistent. This is because the grinding device is likely to have been worn down and dull. As the grinder ages, it will produce different-sized pieces of beans. This produces grounds with varying degrees of coarseness. With these different-sized mini electric coffee grinder particles, it's difficult for your coffee maker to extract the right balance and consistency in flavor.

A blade ceramic grinder uses a propeller-like rotating blade to break beans. It basically chops the beans into smaller and smaller pieces, which are then dropped through a filter into a catcher. While this method works but it's not ideal for producing the best conical burr grinder grind for your beverage. Burr grinders are a better option. A burr grinder has powerful motors, two grinding burrs and is a bigger machine. The burrs are set at a certain distance apart, which will determine the coarseness of the coffee that is ground.

If the burrs are close together, they will pulverize the beans, rather than cutting them. The result is a finer, less coarse ground. They may also be brittle and alter the flavor of your coffee. If the burrs, on the other hand are too far apart they'll result in large chunks of coarsely ground coffee. It is important to select the grinder that's setting is in line with the desired coarseness.

A sharp blade, when adjusted properly, will create a consistent and fine grind for your coffee. If you notice that your grind is becoming more and more uneven, it's best to replace the blade or burrs. It is also advisable to change the grind setting in case you haven't previously, as this will help you achieve an even and consistent grind.

If your grinder produces clumped up grounds it could be a sign the blades are worn or damaged. The clumping occurs due to small particles adhering to one another and larger pieces of grounds producing larger granules which aren't able to dissolve in water. This is more frequent as your burrs get duller.

Uneven Extraction

The size of your coffee grounds is important for flavor extraction, whether you're making a French press pour-over, drip brew or pour-over. Uneven sizes of the grounds can result in uneven extraction and a sloppy cup of coffee.

The beans are cut and shred indiscriminately when they go through a blade mill, which results in an uneven distribution of the size of the grind particles. A blade grinder may produce a mixture of large pieces as well as dust-sized particles and everything else. The different sizes of grinds are extracted at a different speed, creating the cup of coffee beans grinder that is often bitter and inconsistent.

In addition, the lack of uniformity creates problems when the tamping process and filtration. With a burr mill, you can attain an even particle size allowing for more even tamping and filtering, which helps prevent over-extraction and weak beers. If you use a blade grinder, it is more difficult to achieve an even grind. You may find yourself tamping from side to side or using the Stockfleth method (which requires some time to master).

The high speed and heat generated by blade grinders is another problem. This can cause the ground to burn and create a bitter taste. Burr grinders are more cool and don't generate the same amount of heat, which helps preserve the flavor of the bean.

The blade grinder has one last disadvantage: it is easy to grind your beans too fine. Keeping the grinder running continuously produces a lot of heat, which can cause your grounds to become over-extracted, resulting in bitter beverages. To avoid this, always put the grinder off before switching it back on.

Using a blade grinder is a convenient and inexpensive way to grind your own coffee at home but it's not the ideal option for those who are serious about their brewing. You'll want to stick with whole beans and a burr grinder for the best results. You should invest in your the brewing experience and invest in an efficient grinder that will meet every coffee need!

Take a look at our top picks of the best burr mills on the market if you're looking to upgrade your blade grinder. The kind of grinder you pick will impact the quality of your brewing, as well as your cup. So, think about your budget, space and preferred method of brewing before making a decision.

Grounds Burned Grounds

Blade grinders use sharp blades to grind the beans. The blade spins at high speeds similar to a blender. As the blade rotates at a fast speed, heat is produced which can cause a fire to the coffee grounds. These particles can ruin the flavor of your coffee and are not suitable to brew.

For a first-class experience the uniform distribution of particles is required for the best flavor extraction. Since a blade grinder breaks up the beans into different sized pieces, large and small it is difficult to achieve this consistency. A burr mill, on the contrary produces an even distribution of particle sizes that can be replicated over a variety of beverages.

While the advantages of a blade grinder include its low cost and speedy operation, its clear disadvantages are that it produces heat when it is used, creates irregularities in the size of the grind, and lacks control over final particle size. With a bit of practice there are ways to maximize results despite the inherent limitations of this type of grinder.

When a burr mill, the user can easily alter their desired ground size by adjusting the gap between the discs. This allows them to extract the flavor they desire every time from their favorite coffee beans. However, making a good beverage using a grinder takes a lot of trial and error.

An angle grinder is a potent tool that should be utilized only by trained personnel. If it is used incorrectly it can result in an unsafe condition known as grinding burn, that causes localized changes to the metallographic structure of the surface of the workpiece. This can cause cracks that, if unchecked will eventually lead to macropitting and tooth fracture.

Grinding burns can result from a variety of factors, including excessive grinding pressure or inadequate cooling. It can also be caused by improper instruction for the operator. Wear the correct safety equipment when using an angle grinder. This includes safety glasses as well as a face shield and steel toe boots. This will prevent hot sparks from flying off the tool and striking equipment or people close by. Sparks can reach temperatures as high as 3,600 degrees Fahrenheit and can be able to burn through paint or metal.

Brew that is disappointing

A blade grinder cuts your beans indiscriminately, leaving you with grounds that are all different sizes. The ground is extracted at different rates, which results in a weak or bitter cup of aesthetically pleasing Coffee grinders. This affects the balance of a great cup. The soluble components from the beans are extracted slowly and create the flavor.

It's likely that you've heard that using a burr mill instead of a blade mill is the best way for a great beer. However, many people don't know how to use a grinder or even what it can do and so they purchase one of the inexpensive, inflexible, blade grinders that are readily available in grocery stores and kitchen-type places.

These cheap grinders are essentially two-pronged blades that are located at the bottom of an enclosed chamber. It spins fast and chops anything it touches including your beans. The blade is activated by pressing a button. It then chops coffee beans into various sizes. The small pieces are pushed to the bottom of the chamber, and are again chopped, while the larger pieces remain at the top. This causes uneven ground, which are difficult to determine.

These grinders can also cause burns to your beans and ruin the coffee. The heat also removes some of the flavor of your beans, and you're left with a less-than-delicious cup of coffee.

If you've been grinding your own coffee using a blade grinder and you're ready to get rid of it and upgrade to something better. A burr mill will do the job for a fraction the cost, and will produce a much superior result. It's worth it. If you're looking for more control over your beverage try a manual burr grinder such as the Rhino hand grinder. These grinders feature burrs, but they are powered by cranks. This allows you to control the grind more than a plug-in electrical grinder.
