Blade Grinder – Why You Shouldn’t Use OneA blade grinder uses a propeller-like blade (think blenders) to chop coffee beans. They are cheaper than burr mills, and easier to clean, however they don’t create a uniform ground and can cause bitterness or over-extraction in your brew.For a first-class coffee experience, you require uniform distribution of particles. This can only be achieved by using burr mills. This is the reason why coffee lovers hate them.Inconsistent GrindsIf you’ve been using a blade grinder for a while there’s a good chance that your grinding results have changed. The machine is likely to wear out and dull. As the grinder wears down, it will chop up beans into different-sized pieces. Coffeee will produce grounds with varying degrees of coarseness. With the different sizes of coffee particles, it’s hard for your coffee maker to create an even, consistent flavor.A blade grinder breaks beans by rotating a blade that appears like an engine. It chops the beans up into smaller and smaller pieces which are then dropped into a catcher, which is then filtered through the screen. While this method works however, it’s not the best method for making the most perfect grind for your brew. Burr grinders are a better choice. A burr grinder has powerful motors that has two grinding burrs and is a much larger machine. The burrs are set to a specific distance from one another, which determines the coarseness of your ground coffee.If the burrs are too close to each other, they’ll crush the beans rather than cut them. This results in a finer, less coarse ground. They can also be brittle and alter the taste of your coffee. On the other hand, if the burrs are placed too separated, they could result in large chunks of coarsely-ground coffee. It’s crucial to choose the coffee grinder with a setting that matches the degree of coarseness you prefer.A sharp, well-adjusted blade will produce an even 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 blade. It is also advisable to change the grind setting if you haven’t done so previously, as this will help you achieve an even grind.If your grinder produces clumped-up grounds it could be a sign that the blades are worn or damaged. The clumping is caused by tiny particles bonded to each other and larger pieces of ground making larger granules that don’t dissolve well in water. This will happen more often as your burrs become duller.Uneven ExtractionWhether you’re brewing drip, French press, or pour-over the size of your ground plays an important role in flavor extraction. Uneven ground sizes cause uneven extraction, creating an imbalanced cup of coffee.As the beans move through a blade grinder, they are cut and shredded randomly, leading to an uneven distribution of grind particle sizes. A blade grinder may produce a mixture of large pieces as well as dust-sized particles and everything between. The different sizes of grinds produce at a different speed, creating the cup of coffee that is often bitter and inconsistent.Inconsistency can cause problems when tamping or filtering. With a burr grinder you can get an even particle size that allows for more even tamping and filtration that prevents over-extraction and weak beer brews. With a blade grinder it is more difficult to achieve an even grind and you might be tamping from side to side or using the Stockfleth method (which requires some time to master).The high speed and the heat produced by blade grinders is a different problem. The grounds can be burned and cause a bitter taste. Burr grinders generate less heat and are cooler, which preserves the flavor of the beans.Another drawback of a blade grinder is that it’s extremely easy to over-grind your beans. The grinder will generate a lot heat and eventually your grounds will 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.The use of a blade grinder is a simple and cost-effective method of grinding your own coffee at home however, it’s not the best choice for those who are serious about their coffee brewing. It is recommended to use whole beans and use a burr grinder to get the best results. Make sure you purchase a high-quality coffee grinder that will meet all your needs.If you’re ready to upgrade your blade grinder, look through our top picks for the most efficient burr grinders on market. The type of grinder you choose will impact the quality of your brewing, as well as your beverage. So, think about your budget, space and preferred brewing method before making a choice.Grounds Burned GroundsWith the blade grinder is an extremely sharp blade that moves like a blender at high speed to cut the beans. The blade’s rapid movement produces heat, which can ignite some of the coffee grounds. These particles can ruin the flavor of your coffee and are not ideal to brew.To ensure a top-quality experience an even distribution of particles is necessary for optimal flavour extraction. This is not possible with a blade mill that is able to break the beans up into large and small pieces. A burr mill, however creates a uniform distribution of particle sizes that can be replicated over a number of different brews.While the benefits of a blade grinder are its low cost and speedy operation, its major drawbacks are that it generates heat when it is used, creates variations in the size of the grind and is not able to control the final particle size. With a little practice there are ways to improve results despite the inherent limitations of this type of grinder.When used in conjunction with a burr mill, users can easily alter the gap between the grinding discs in order to adjust the exact ground size of their choice. This lets them to extract the flavor they desire every time from their favourite coffee beans. It requires a lot of practice to make a good beverage using a blade grinder.Angle grinders are a powerful tool that should only be employed by professionals. If used improperly, it can cause an unsafe condition known as grinding burn that causes localized changes to the metallographic structure of the surface of the workpiece. This can lead to cracking that, if unchecked, can eventually result in 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 training for operators. If you intend to use an angle grinder, make sure you wear the appropriate PPE including gloves with a face shield safety glasses, steel toe boots and long sleeves. This will prevent hot sparks from flying out of the wheel and striking nearby equipment or people. Sparks can be capable of reaching temperatures as high 3,600 degrees Fahrenheit, and they can be destructive to materials like paint or even metal.Brew that is disappointingA blade grinder can chop your beans up indiscriminately and result in different-sized beans. The unevenly sized grounds release at different rates in your coffee maker and this leads to an unpalatable or weak cup of brew. This ruins the balance of a good cup. The soluble components from the beans are slowly extracted making the flavor.You’ve probably heard it said that using a burr mill instead of a blade mill is the best method to make the best beer. But many people don’t know how to use a grinder or even what it is and so they purchase one of the cheap, uncontrollable, blade grinders that are easily found in kitchen and grocery store places.The grinders that are available for sale are essentially two-pronged blades that are in the middle of an enclosed chamber. It spins quickly and chops anything it touches, including beans. You press a button to start the grinder and the blade chops up your beans into a plethora of different-sized pieces. The smaller pieces are tossed to the bottom, and are chopped again, while the larger pieces stay towards the top of the chamber. This makes for uneven grounds which are difficult to accurately measure – which is why you aren’t certain of the amount of ground coffee your grinder made.Another issue with these grinders is that they generate plenty of heat as they grind, which could burn your beans and ruin the coffee you drink. The heat can also take away some of the flavor of your beans. This leaves you with a less than delicious cup of coffee.If you’ve been grinding your coffee yourself with a blade mill, it’s time to upgrade to a more effective. A burr mill will do the job at a fraction of the cost, and provide the same results. It’s worth the investment. If you’re looking to have more control over the brew Try a manual grinder like the Rhino hand grinder. These grinders are equipped with burrs, but are powered by turning an engine, which gives more control than a plug-in or electric grinder.
