Blade Grinder - Why You Shouldn't Use One
Blade grinders use an e-type propeller (think blenders) to chop coffee beans. They are less expensive than burr mills, and easier to clean, however they don't provide a uniform grind and can cause bitterness or excessive extraction in your coffee.
A top-quality coffee experience requires uniform distribution of particles, something that can only be achieved by using a burr grinder. This is the reason why coffee lovers hate them.
Inconsistent Grinds
If you've used a blade grinder for some time there's a good chance that your grinding results have become inconsistent. This is because the machine is likely to have become dull and worn out. As the grinder wears down, it will chop up beans into different-sized pieces. This produces grounds with varying levels of coarseness. With the different sizes of
coffee beans grinder machine particles, it's difficult for your coffee maker to create a balanced, consistent flavor.
Blade grinders use an e-rotating blade that resembles a propeller to break the beans. It is basically a way of cutting beans into smaller and smaller pieces, which are then dropped through a screen into the catcher. This method is efficient, but it doesn't produce the most efficient grind for your beverage. Burr grinders are a better choice. A burr grinder has powerful motors with two grinding burrs, and is a much larger machine. The burrs are set at a specific distance, which will determine the quality of the coffee that is ground.
If the burrs are too close together, they will pulverize the beans instead of cutting them. The result is a more fine more refined, less coarse ground. They also tend to be brittle, which can negatively affect the taste of your coffee. On the other hand, if the burrs are too far apart, they will create large chunks of coarsely-ground coffee. It is essential to choose an espresso grinder with a setting that corresponds to the desired coarseness.
A sharp blade, if adjusted correctly, will result in a consistent and fine grind for your coffee. If you find that your grind is becoming more and more uneven, it's a good idea to replace the blade or burrs. You should also consider changing the grind setting if you haven't done so already to help you achieve a more uniform grind.
It's also worth noting that if your machine produces ground that has clumped together, this is a sign of worn-out or damaged blades. The clumping happens because tiny particles bind to one another and larger pieces of ground are formed, creating larger granules which don't dissolve in water. As your burrs become more and more dull this will occur more often.
Uneven Extraction
The size of your coffee grounds is important for flavor extraction, whether you're using a French press pour-over, drip brew or pour-over. Uneven ground sizes can cause uneven extraction, resulting in an unbalanced cup of coffee.
As the beans move through a blade grinder, they are sliced and shredded indiscriminately resulting in an uneven distribution of grind particle sizes. A blade
smart grinder produces smaller fragments, near-dust size particles and everything in between. The different sizes of grinds extract at an uneven speed, creating the cup of coffee that is usually bitter and inconsistent.
The lack of uniformity also causes problems with filtering and tamping. With a burr grinder, you can attain an evenly ground particle size allowing for more uniform tamping and filtering which prevents over-extraction and weak beers. It is more difficult to achieve an even grind using a blade. You may need to tamp from side to side, or employ the Stockfleth Method (which requires some practice).
Another problem with blade grinders is their speed and the generation of heat. They can cause the ground to burn and produce a bitter flavor. Burr grinders are more cool and don't produce the same amount of heat, which helps preserve the flavor of the beans.
The final drawback of the blade grinder is that it's easy to over-grind your beans. Keeping the grinder running continuously produces heat and will eventually cause your beans to be excessively extracted, which can result in bitter beverages. To avoid this, you should always pause the grinder before switching it back on.
Blade grinders are a convenient, inexpensive way to grind coffee at home. However they're not the best choice for those who are serious about their coffee-brewing. You'll want to stick with whole beans and use a burr grinder to get the best burr grinder (

The kind of grinder you pick will affect the quality of your brewing as well as your cup. Consider your budget, space, and preferred method of brewing prior to making your decision.
Grounds burned Grounds
Blade grinders use a sharp blade to grind the beans. The blade rotates at high speeds, like a blender. When the blade spins at a rapid pace, heat is produced which could cause the burning of some of your coffee grounds. These charred particles aren't good for brewing and can leave a bitter taste in your cup of coffee.
A top-quality coffee experience requires uniform distribution of the particles to ensure optimal flavor extraction during the brewing process. Since a blade grinder breaks up the beans into different sized pieces, small and large it is impossible to achieve this level of consistency. A burr grinder on the other hand can ensure a uniform distribution of particles that can be replicated across a variety of types of brews.
While the advantages of a blade grinder include its low cost and speedy operation, its clear disadvantages are that it creates heat when used, causes irregularities in the size of the grind, and lacks control over final particle size. There are ways to improve the results with this type of grinder despite its inherent limitations.
When used in conjunction with a burr mill, the user can easily alter the gap between the grinding discs in order to adjust the exact ground size that they prefer. This lets users to extract the desired flavor every time they drink their favorite roast beans. However, making a good brew with a blade grinder is a process that requires a lot trial and error.
Angle grinders are a powerful tool that should only be employed by professionals. If it is used incorrectly it can result in the dangerous condition known as grinding burn, which causes localized changes in the metallographic structure of the surface of the workpiece. This can lead to cracking, which, if not checked, could lead to macropitting and tooth fracture.
Grinding burn can result from a variety of reasons, such as excessive grinding pressure or inadequate cooling. It could also be caused by poor operator training. If you plan on using an angle grinder, be sure you wear the correct PPE such as gloves and a face shield, safety glasses, steel toe boots and long sleeves. This will prevent hot sparks from flying off the tool and hitting equipment or people nearby. The sparks can be as hot as 3,600 degF, and can burn through the materials like paint or even metal.
Brew that isn't great.
A blade grinder cuts your beans indiscriminately and leaves you with ground which are of different sizes. The uneven ground extracts coffee at different rates, leading to a weak or bitter cup of coffee. This can ruin the balance of a great cup. The soluble compounds from your beans are slowly extracted and create the flavor.
You've probably heard it said that using a burr mill instead blade mills is the best way for a great brew. But many people don't know how to use a
burr mill grinder grinder or even what it does and so they purchase one of the flimsy, uncontrollable blade grinders readily available in grocery stores and kitchen-type places.
These grinders are basically a two-pronged blade that is at the bottom of an enclosed chamber. It spins fast and cuts anything it comes in contact with, including your beans. You press a button start the grinder and the blade chops up your beans into a variety of different sized pieces. The smaller pieces fall to the bottom of the chamber, and are chopped again, while the larger pieces remain at the top. This makes for uneven grounds that are hard to accurately measure - which is why you aren't certain of the amount of ground coffee your grinder made.
These grinders could also burn your beans and ruin your coffee. The heat also takes away some of the flavor of your beans, so you're left with a less-than-delicious cup of
coffee bean grinder machine.
If you've grind your coffee by yourself using a blade mill it's now time to upgrade to a more efficient. A burr grinder can do the job for a fraction of the price and provide a better result. It's worth it. If you're looking to have more control over the brew Try a manual grinder such as the Rhino hand grinder. These grinders feature burrs, but are powered by a crank. This allows you to control the grind more than an electrical or plug-in grinder.
