Blade Grinder - Why You Shouldn't Use One

Blade grinders are equipped with a blade that looks like propellers (think blenders). They are used to chop coffee grinders sale beans. They are less expensive than burr mills and easy to clean, but they don't produce uniform ground and can cause bitterness or over-extraction in your brew.

A first-class coffee experience demands uniform distribution of the particles, something that is only possible with the use of a burr grinder. This is the reason why coffee snobs hate burr grinders.

Inconsistent Grinds

If you've used a blade grinder for some time it is likely that your grinding results have changed. This is because the grinder is likely to have been worn down and dull. As the grinder wears out, it will chop up beans into different-sized pieces. This produces grounds with different levels of coarseness. With these various-sized coffee particles, it's difficult for your coffee maker to extract a balanced, consistent flavor.

A blade grinder cuts the beans with a rotating blade that appears like an engine. It is basically a way of cutting beans into smaller and smaller chunks, which are then dropped through a screen into the catcher. This technique is efficient however it's not the best burr grinder grind possible for your brew. A better option is the burr grinder. A burr grinder comes with powerful motors that has two grinding burrs and is a bigger machine. The burrs can be set at a certain distance apart and will determine the quality of the coffee machines with grinder being ground.

If the burrs get too close, they pulverize rather than cut the beans. The result is a finer, less coarse ground. They also tend to be brittle, which can negatively impact 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 is important to select a grinder that's setting matches the coarseness you want.

A sharp blade, if adjusted properly, will produce a consistent and fine grind for your coffee. If you notice that your grind is becoming more uneven, it could be time to replace the blade or burrs. If you haven't done so, you must change the grind setting to get an even grinding.

If your grinder produces clumped-up grounds, it could be an indication that the blades are worn or damaged. The clumping happens when tiny particles stick to each other, and larger pieces of ground, producing larger granules that don't dissolve in water. As your burrs grow and dull it will occur more often.

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 can result in uneven extraction and an unbalanced cup of coffee.

As the beans circulate through a blade grinder, they are sliced and shredded indiscriminately resulting in an uneven distribution of the grind particle sizes. A blade smart grinder pro produces a mix of larger fragments, small particles and everything in between. The different sizes of grinds are extracted at different rates, which results in a sloppy and often bitter cup of coffee.

Inconsistency can result in problems with tamping and filtering. With a burr grinder you can achieve an evenly-sized particle size that allows for more uniform tamping and filtering that prevents over-extraction and weak brews. It is more difficult to achieve a consistent grind with a blade grinder. You may have to tap from side to side or use the Stockfleth Method (which requires some practice).

Another problem with blade grinders is their high speed and high heat generation. This can cause the ground to get burned and create a bitter taste. Burr grinders are more cool and don't generate the same amount of heat, which preserves the flavors of the bean.

The blade grinder has one last disadvantage: it is very easy to grind your beans too fine. Continuously running the grinder produces heat, and eventually causes your grounds to become over-extracted, resulting in a bitter brew. To avoid this, always stop the grinder prior to switching it back on.

Blade grinders are an easy, inexpensive way to grind coffee at home. However they're not the ideal choice for those who are serious about their coffee brewing.

Grounds burned Grounds

With a blade grinder, you're using a sharp blade that spins like a blender at high speed to chop up the beans. When the blade spins at a fast speed, heat is produced which could cause the burning of some of your coffee grounds. These particles will alter the flavor of your coffee and are not suitable to brew.

To ensure a top-quality experience the uniform distribution of particles is necessary for the best home espresso grinder flavor extraction. Since blade grinders break the beans into different sized pieces, small and large it is difficult to achieve this level of consistency. A burr mill, on the contrary, produces a uniform distribution of particle sizes that can be reproduced over a variety of brews.

Blade grinders have many advantages, including their low price and speedy operation. However, they have some disadvantages like the fact that they produce heat when in use and can produce inconsistent grind sizes and have no control over the final particle size. With a little practice however, there are ways to optimize results despite the inherent limitations of this kind of grinder.

When combined with a burr grinder, the user is able to easily adjust the distance between the grinding discs, allowing them to fine-tune the exact size of ground that they prefer. This allows them to get all the desired flavours from their favourite roast beans every time. It takes a lot of practice to make a great drink using a grinder blade.

Angle grinders are a powerful tool that should only be used by professionals. It can cause grinding burn if it is used improperly. This causes localized changes to the metal surface of the workpiece. This can cause cracks that, if left unchecked could eventually lead to macropitting and tooth fracture.

Grinding burn is a serious issue that can be caused by a range of factors including excessive grinding pressure, inadequate cooling, or inadequate training for operators. If you intend to use an angle grinder, be sure you wear the appropriate PPE, including gloves and a face shield, safety glasses, steel-toe boots and long sleeves. This will stop any sparks of heat from flying off the tool and hitting people or equipment close by. These sparks can be as hot as 3,600 degrees Fahrenheit and are capable of burning through the materials like paint or metal.

Brew that is disappointing

A blade grinder chops up your beans indiscriminately and leaves you with beans that are all different sizes. These uneven grounds are extracted at different rates in your coffee maker and this leads to a bitter or weak cup of brew. The problem with this is that it ruins the balance that makes a great cup of coffee. The soluble compounds in your beans are extracted over time, resulting in the flavor that makes your coffee scrumptious.

You've probably heard that using a burr mill instead of a blade mill is the best method to make a great brew. Many people aren't aware how to use a burr mill or even what it does, so they buy one of the cheap, uncontrollable blade grinders that are readily available in supermarkets and other kitchen-type places.

These cheap grinders are essentially two-pronged blades that are at the bottom of an enclosed chamber. It spins quickly and chops anything it touches, including beans. The blade is activated by pressing the button. It then chops coffee beans into various size pieces. Small pieces drop to the bottom and get chopped all over again, while the larger pieces stay towards the top of the chamber. This causes uneven ground which are difficult to accurately measure - which is why you aren't certain of the amount of ground coffee you made with your grinder.

Another problem with these grinders is that they create plenty of heat as they grind, which can burn your beans and ruin your coffee. The heat also removes some of the flavor of the beans, which means you're left with a mediocre 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 an even better result. It's 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 plug-in or electric grinder.
