Blade Grinder - Why You Shouldn't Use One

Blade grinders use an e-type propeller (think blenders) to chop coffee beans. They are cheaper than burr mills and easy to clean, however they don't produce uniform ground and can cause bitterness and excessive extraction in your coffee.

A top-quality coffee experience requires uniform distribution of particles and this can only be achieved by using a burr grinder. This is why coffee lovers hate burr grinders.

Inconsistent Grinds

If you've used a grinder with a blade for a long time it is likely that your grinding results have become inconsistent. The grinder is likely to be worn out and dull. As the grinder wears down it will break up beans into different sizes. This will produce grounds with different degrees of coarseness. It's difficult for your coffee maker to create an even, balanced flavor with these various-sized particles.

A blade grinder breaks beans using a rotating blade that appears like an engine. It basically chops the beans into smaller and smaller chunks that are then thrown through a filter into a catcher. Although this method is effective however, it's not the best method for making the most perfect grind for your beverage. Burr grinders are a better option. A burr grinder comes with a powerful motor, two grinding burrs and is a larger machine. The burrs can be set to a certain distance and will determine the degree of coarseness of the ground coffee.

If the burrs get too close, they pulverize rather than cut the beans. This results in a finer and less coarse grind. They also tend to be fragile, which could negatively impact your coffee's taste. On the other side, if the burrs are placed too far apart, they will create large chunks of coarsely-ground coffee. It is crucial to select a coffee grinder that has an adjustment that is in line with the level of coarseness you want.

A sharp blade, adjusted correctly, will result in a consistent and fine grind for your coffee. If you notice that your grind is becoming more and more uneven, it's best to replace the blade or burrs. If you haven't yet done so, you must also change the grind setting to get more even grinding.

It's also worth noting that if your grinder creates ground that is clumpy it is an indication of worn-out or damaged blades. The clumping is caused by small particles adhering to each other and larger pieces of ground, creating larger granules that do not dissolve well in water. As your burrs become more and more dull, this will happen more frequently.

Uneven Extraction

The size of your coffee grounds is vital for flavor extraction, whether you're making a French press pour-over, drip brew or pour-over. Uneven ground sizes lead to uneven extraction and a sloppy cup of coffee.

The beans are cut into pieces and shredded in a random manner when they go through a blade mill, resulting in an unbalanced distribution of the size of the grind particles. A blade grinder can create a mix of large fragments that are dust-sized, as well as evercoffee and are not ideal for brewing.

A first-class coffee experience demands a uniform particle distribution for optimal flavour extraction during the brewing process. Since the blade grinder breaks the beans into unevenly sized pieces, small and large it is difficult to achieve this level of consistency. A burr mill, however creates a uniform distribution of particle sizes that can be reproduced across a variety of brews.

While the advantages of a blade grinder are its low cost and quick execution, its main disadvantages are that it creates heat when used, causes inconsistencies in grind size, and is not able to control the final particle size. With a bit of practice, however, there are ways to optimize results despite the inherent limitations of this type of grinder.

When combined with a burr grinder the user is able to easily adjust the gap between the grinding discs, allowing them to fine-tune the exact ground size of their preference. This lets them extract all of the desired flavours from their favourite beans each time. However, making a good brew with a blade grinder takes a lot of trial and trial and.

Angle grinders are powerful devices that should only be employed by professionals. If it is used incorrectly it could cause an unsafe condition known as grinding burn which causes localized changes in the metallographic structure of the workpiece's surface. This could cause cracks that is not properly checked, can eventually lead to teeth fracture and macropitting.

Grinding burn can be caused by a variety of reasons, such as excessive grinding pressure or insufficient cooling. It can be caused by inadequate operator training. If you intend to use an angle grinder, be sure you wear the appropriate PPE, including gloves, a face shield, safety glasses, steel-toe boots and long sleeves. This will prevent hot sparks from flying off the machine and hitting equipment or people close by. These sparks can reach temperatures as high as 3,600 degF, and are capable of burning through materials such as paint or even metal.

A disappointing Brew

A blade grinder chops up your beans randomly and leaves you with ground which are of different sizes. These uneven grounds release at different rates in your coffee maker, which results in the cup being weak or bitter of coffee. The issue is that it destroys the balance that makes a good cup of coffee. The soluble compounds in your beans are extracted over time, which creates the flavor that makes your coffee taste delicious.

You've probably heard it said that using a burr mill instead blade mills is the best way to make an excellent beverage. Many people don't understand what a burr mill does. They buy the cheap blade grinders that are difficult to control and can buy at supermarkets and places that are kitchen-like.

In essence, these grinders have a double-pronged blade at the bottom of the chamber that spins rapidly and cuts up whatever it comes into contact with, including your coffee beans. The blade is activated by pressing the button. It then chops your coffee beans into different sizes. Small pieces are pushed to the bottom of the chamber and are chopped again, while the larger pieces remain at the top. This causes uneven grounds that are difficult to determine.

These grinders can also burn your beans which can ruin the coffee. The heat can also remove some of the flavor from your beans. This can leave you with a a less than delicious cup of coffee.

If you've grind your coffee by yourself using a blade mill it's time to upgrade to a more efficient. A burr mill can complete the job for a fraction the price, and produce the same results. It's worth it. If you want more control over your brew, try a La Cafetière Black Manual Coffee Grinder - Premium Quality burr grinder such as the Rhino hand grinder. These grinders are equipped with burrs, but are powered by a crank, which provides more control than a plug-in or Aigostar Portable Electric Coffee Grinder - Stainless Steel grinder.
