Blade Grinder – Why You Shouldn’t Use One
A blade grinder employs an e-type propeller (think blenders) to chop coffee beans. They are cheaper than burr mills, and easier to clean, but they don’t provide a uniform grind and can cause bitterness and excessive extraction in your coffee.
To enjoy a top-quality coffee experience, you require uniform particle distribution. This can only be achieved using burr mills. This is why coffee snobs hate burr grinders.
Inconsistent Grinds
You may have noticed the results of your grinding aren’t always consistent when you’ve used a blade mill over a long period of time. This is because the grinding device has likely been worn down and dull. As the grinder gets older, it will produce different-sized pieces of beans. This can result in different degrees of coarseness. With these various-sized coffee particles, it’s difficult for your coffee maker to create the right balance and consistency in flavor.
Blade grinders use the same propeller-like blade to break beans. It cuts the beans into smaller and smaller pieces, which are then put into a catcher via a screen. While this method is effective, it’s not ideal for making the most perfect grind for your drink. A better option is the burr grinder. A burr grinder has a powerful motor, two grinding burrs and is a bigger machine. The burrs are set to a certain distance, which will determine the quality of the coffee that is ground.
When the burrs get too close, they will crush rather than cut the beans. This results in a finer and less coarse grind. They are also more fragile, which could negatively impact the taste of your coffee. On the other however if the burrs are too far apart, they will result in large chunks of coarsely-ground coffee. It is crucial to select a coffee grinder that has an adjustment that is in line with the degree of coarseness you prefer.
A sharp, properly adjusted blade will result in a consistent and fine grind for your coffee. If you notice that your grind is becoming increasingly uneven, it may be time to replace the burrs or blade. It is also advisable to change the grind setting if you haven’t already in order to allow you to achieve an even grind.
If your grinder is producing clumped-up grounds, it could be a sign the blades are worn or damaged. The clumping is caused by tiny particles sticking to one another and larger pieces of ground making larger granules that don’t dissolve well in water. As your burrs grow and dull it is more frequent.
Uneven Extraction
No matter if you’re using drip, French press, or pour-over the size of your ground plays an important role in flavor extraction. Uneven sizes of the grounds cause uneven extraction, resulting in an imbalanced cup of coffee.
The beans are cut into pieces and shred indiscriminately when they go through a blade mill, which results in an unbalanced distribution of the size of the grind particles. A blade grinder produces a mix of larger fragments, smaller particles and everything in between. These different grind sizes produce at a different speed, creating a cup of coffee that is often bitter and inconsistent.
The lack of uniformity also creates problems when filtering and tamping. With a burr mill, you can get an even particle size, which allows for better tamping and filtration, which can prevent excessive extraction. With a blade grinder, it is more difficult to get an even grind and you may find yourself tamping from side to side or using the Stockfleth method (which requires some practice).
Another problem with blade grinders is their high speed and high heat generation. The grounds can be burned and produce a bitter flavor. Burr grinders create less heat and are cooler, which preserves the flavor of the beans.
A final downside of grinding with a blade is that it’s extremely easy to over-grind your beans. The grinder can generate lots of heat, and, eventually, your beans will become over-extracted. This will result in a bitter brew. To avoid this, you should always stop the grinder before turning it back on.
Blade grinders are an easy, inexpensive way to grind coffee at home. However, they’re not the best choice for those who are serious about their brewing. It is recommended to use whole beans and a burr grinder to get the best burr grinder (just click the up coming article) results. Make sure you purchase a high-quality coffee grinder that will meet all your requirements.

The kind of grinder you select will impact the quality of your brewing and your beverage. So, think about your budget, space, and preferred method of brewing before making your decision.
Burned Grounds
With the blade smart grinder pro it’s a sharp blade that rotates like a blender at a rapid speed to cut the beans. The blade’s speedy movement creates heat, which can burn some of the coffee grounds. These burned particles aren’t ideal for the brewing process and can leave a bitter taste in your cup of coffee.
For a truly exceptional experience an even distribution of particles is required for optimal flavour extraction. Because blade grinders break the beans into unevenly sized pieces, large and small it is impossible to achieve this level of consistency. A burr mill, on the contrary, produces an even distribution of particle sizes that can be replicated over a number of beverages.
Blade grinders offer a variety of advantages, such as their low cost and quick operation. However, they do have some disadvantages like the fact that they produce heat when in use, produce inconsistent grind sizes and have no control over the final particle size. There are ways to improve results with this type of grinder, despite its inherent limitations.
When using a burr mill, the user is able to easily adjust their desired ground size by adjusting the distance between the discs. This lets them get all the desired flavors from their favorite roasted beans every time. It requires a lot of practice to make a great beverage using a blade grinder.
Angle grinders are a powerful tool that should only be employed by professionals. If used improperly, it can cause a dangerous condition known as grinding burn that causes localized changes to the metallographic structure of the surface of the workpiece. This can cause cracking, which should be checked. If not, it could lead to macropitting and teeth fracture.
Grinding burn is a serious issue that can be caused by a range of factors, including excessive grinding pressure, inadequate cooling, or inadequate operator training. If you intend to use an angle grinder, be sure to wear the proper PPE including gloves with a face shield safety glasses, stainless steel manual coffee grinder-toe boots and long sleeves. This will prevent sparks of heat from flying off the tool and striking equipment or people nearby. These sparks can be as hot as 3,600 degrees Fahrenheit and are capable of burning through paint or metal.
A disappointing Brew
A blade grinder chops up your beans indiscriminately and leaves you with ground that vary in size. This uneven ground extracts at different rates, resulting in the cup being bitter or weak of stainless steel coffee grinder. This affects the balance of a fantastic cup – the soluble compounds from the beans are slowly extracted, creating the flavor.
You’ve probably heard it said that using a burr mill instead of a blade mill is the best way to make the best beer. Many people don’t even know what a burr mill does. They purchase the cheap, uncontrollable blade grinders they can buy at supermarkets and kitchen-type places.
The grinders that are available for sale are essentially a two-pronged blade that is at the bottom of an enclosed chamber. It spins quickly and chops anything it touches, including your beans. You press a button start the grinder and the blade cuts 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 results in uneven grounds that are difficult to determine.
Another problem with these grinders is that they produce a lot of heat while they grind, which can cause the beans to burn and ruin the coffee you drink. The heat also takes away some of the flavor of the beans, which means you’re left with a bland cup of coffee.
If you’ve been grinding your own coffee using a blade grinder, it’s time to retire it and upgrade to something better. A burr mill can do the job at a fraction of the cost, and will produce the same results. It’s worth the investment. Try an manual burr mill, such as the Rhino Hand Grinder if you want to have greater control over the brew. These grinders feature burrs but are powered by turning an engine, which gives more control than an electric or plug-in niche grinder.
