Blade Grinder Why You Shouldnt Use One Blade grinders are equipped with blades that look like a propeller think blenders They are used to chop coffee beans They are cheaper than burr mills and are easy to clean but they dont produce uniform ground and can cause bitterness and overextraction in your brew To get the best coffee experience you must have uniform distribution of particles This is only possible using a burr mill This is why coffee snobs loathe them Inconsistent Grinds You may have noticed your grinding results are inconsistent when youve used a blade grinder over a long period of time This is because the grinding device is likely to have been worn down and dull As the grinder gets older it will produce different sized pieces of beans This results in ground with different levels of coarseness Its challenging for your coffee maker to get a consistent balanced flavor due to the different sizes of the particles A blade grinder makes use of a propellerlike rotating blade to break the beans It chops the beans up into smaller and smaller pieces which are then put into a catcher via the screen Although this method is effective however its not the best method to get the perfect grind for your beverage Burr grinders are a better choice A burr grinder is a much larger machine with a powerful motor and two grinding burrs The burrs can be placed at a specific distance which will determine the degree of coarseness of the ground coffee If the burrs are too close to each other they will crush the beans rather than cutting them The result is a more fine less coarse ground They are also more fragile which could negatively affect the taste of your coffee On the other side if the burrs are too spread out they will result in large chunks of coarselyground coffee It is crucial to select a grinder that has an adjustment that is in line with the coarseness you desire A sharp properly adjusted blade will result in an even and fine grind for your coffee If you notice that your grind is becoming more uneven it could be time to replace the burrs or blade If you havent yet done this you must also alter the grind setting to achieve more even grinding If your grinder produces clumped up grounds it could be an indication that the blades are worn out or damaged The clumping happens when small particles adhere to each other and larger pieces of ground are formed making larger granules that wont dissolve in water As your burrs become more and more dull this is more frequent Uneven Extraction No matter if youre using drip French press or pourover the size of your ground plays an important role in the extraction of 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 randomly leading to an uneven distribution of the grind particle sizes A blade grinder creates smaller fragments smaller particles and everything between Different grind sizes are extracted at a different rate resulting in the cup of coffee that is usually bitter and inconsistent The lack of uniformity also creates problems when filtering and tamping With a burr mill you can achieve an even particle size allowing for better tamping and filtration which prevents overextraction With a blade grinder it is more difficult to get an even grind and you might 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 issue The grounds can be burned and produce a bitter flavor Burr grinders generate less heat and are cooler preserving the flavor of beans Another drawback of the blade grinder is that its very easy to overgrind your beans Running coffee machine and grinder Coffeee generates a lot of heat which can cause your beans to be excessively extracted which can result in a bitter brew To avoid this stop your grinder prior to switching it back on Using a blade grinder is a simple and affordable method of grinding your own coffee at home but its not the best option for those serious about their coffeemaking You should stick to whole beans and use a burr grinder to get the most effective results Invest in a quality coffee grinder that can meet all your requirements Weve compiled a list of our top choices of the top burr mills available on the market to upgrade your blade grinder The kind of grinder you select will impact the quality of your brewing as well as your cup So consider your budget space and preferred method of brewing before making your decision Grounds burned Grounds A blade grinder employs a sharp blade to crush the beans The blade spins at high speed like a blender The blades speedy movement creates heat which can burn some of the coffee grounds These particles will alter the flavor of your coffee and are not ideal for brewing To ensure a topquality experience a uniform distribution of particles is essential to ensure the best flavor extraction Since blade grinders break the beans into unevenly sized pieces large and small it is impossible to achieve this consistency A burr grinder on the other hand achieves an even distribution of particles that is reproducible across a variety of types of brews While the advantages of a blade grinder include its low cost and speedy operation its clear drawbacks are that it generates heat when used causes irregularities in the size of the grind 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 combined with a burr grinder users can easily adjust the distance between the grinding discs allowing them to finetune the exact ground size that they prefer This lets them extract all of the desired flavors from their favorite beans each time However creating a quality drink using a blade grinder requires a lot of trial and trial and Angle grinders are powerful devices that should only be used by professionals It could cause grinding burn if employed incorrectly This can cause localized changes to the metallographic surface of the workpiece This can cause cracks that if not addressed can eventually result in macropitting and tooth fracture Grinding burn can be caused by a variety of factors including excessive grinding pressure or inadequate cooling It can also be caused by improper operator training Wear the correct safety equipment when using an angle grinder This includes safety glasses with a face shield as well as steel toe boots This will prevent sparks of heat from flying off the tool and striking equipment or people nearby These sparks can be as hot as 3600 degrees Fahrenheit and can be able to burn through the materials like paint or even metal Disappointing Brew A blade grinder cuts your beans indiscriminately and leaves you with beans that vary in size The unevenly sized grounds extract at different rates in your coffee maker which results in an unpalatable or weak cup of coffee This ruins the balance of a good cup the soluble compounds from your beans are slowly extracted creating the flavor Youve probably heard that using a brewing burr grinder instead of a blade is the best method to ensure the best drink Many people dont even know what a burr mill is They purchase the cheapest blade grinders that are uncontrollable and difficult to control they can find in supermarkets and places that are kitchenlike These grinders are basically twopronged blades that are in the middle of an enclosed chamber It spins rapidly and cuts anything it comes in contact with including beans The blade is activated by pressing a button It then chops coffee beans into various sized pieces Small pieces are pushed to the bottom of the chamber and are then chopped up again whereas the larger pieces remain at the top This causes uneven ground that are hard to accurately measure which is the reason you cant be certain of the amount of ground coffee your grinder made These grinders can also cause burns to your beans which can ruin the coffee The heat can also take away some of the flavor from your beans so youre left with a mediocre cup of coffee If you have been grinding your coffee yourself using a blade mill its time to upgrade to a more efficient A burr mill will do the job at a fraction of the cost and provide a much superior result Its worth it Try using a manual burr mill such as the Rhino Hand Grinder if you would like to have more control over your brew These grinders feature burrs but are powered by an engine which gives more control than a plugin or electric grinder
