Blade bean grinder coffee machine – Why You Shouldn’t Use One
A blade grinder uses propeller-like blades (think blenders) to chop coffee beans. They are cheaper than burr mills and are easy to clean, but they don’t provide a uniform grind and can cause bitterness or excessive extraction in your coffee.
For a first-class coffee experience, you must have uniform distribution of particles. This can only be achieved by using burr mills. It’s not surprising that coffee snobs hate them.
Inconsistent Grinds
You may have noticed that your grinding results are inconsistent when you’ve used a blade grinder over a long period of time. The grinding device is likely be worn out and dull. As the grinder wears out it will cut beans into various sizes. This produces grounds with varying levels of coarseness. With these various-sized coffee particles, it’s hard for your coffee maker to extract an even, consistent flavor.
A blade grinder cuts the beans with a rotating blade that appears like a propeller. It cuts the beans into smaller and smaller pieces, which are then tossed into a catcher via a screen. This technique is efficient, but it doesn’t produce the finest grind possible for your beverage. Burr grinders are a better choice. A burr grinder is a larger espresso machine with grinder that has a powerful motor and two grinding burrs. The burrs are set to a certain distance which determines the coarseness of the coffee being ground.
If the burrs are too close to each other, they’ll crush the beans instead of cutting them. This means that the resultant grounds are less coarse and more fine. They are also more fragile, which could negatively impact the taste of your coffee. On the other hand when the burrs are too far apart, they will result in large chunks of coarsely-ground coffee. It is essential to select a coffee grinder that has an appropriate setting to match the level of coarseness you want.
A sharp, well-adjusted blade will result in a consistent and fine grind for your coffee. If you notice your grind is becoming more and more uneven, it’s probably a good idea to replace the blade or burrs. You should also think about changing the grind setting if you haven’t done so previously to help you achieve an even grind.
It’s also worth noting that if your machine produces ground that is clumpy, this is an indication of worn-out or damaged blades. The clumping occurs when tiny particles bind to one another and larger pieces of ground are formed, creating larger granules which don’t dissolve in water. This is more frequent as your burrs get duller.
Uneven Extraction
If you’re brewing drip, French press, or pour-over the size of your grounds play an important role in the extraction of flavor. Uneven ground sizes can lead to uneven extraction and a sloppy cup of coffee.
The beans are cut into pieces and shredded randomly as they move through a blade mill, resulting in an unbalanced distribution of grind particle size. A blade grinder produces a mix of larger fragments, smaller particles, and everything between. The different sizes of grinds extract at uneven rates resulting in an inconsistent and often bitter cup of coffee.
Lack of uniformity can also cause problems with tamping or filtration. With a burr grinder you can get an evenly ground particle size, allowing for more even tamping and filtering which prevents over-extraction and weak beers. With a blade grinder, it is more difficult to achieve an even grind, and you may be tamping from side to side or using the Stockfleth method (which takes some practice).
The high speed and the heat produced by blade grinders is a different problem. This can cause the ground to get burned and produce a bitter taste. Burr grinders create less heat and are cooler, thus preserving the flavor of the beans.
Another drawback of grinding with a blade is that it’s very easy to over-grind your beans. The grinder can generate plenty of heat and, eventually, your beans will be over-extracted. This will result in a bitter brew. To avoid this, you must pause your grinder before turning it on again.
The use of a blade grinder is an efficient and affordable method of grinding your own coffee at home, but it’s not the ideal option for those serious about their coffee-making. You’ll want to stick with whole beans and use burr grinders for the most effective results. Invest in your the brewing experience and invest in a stainless steel grinder that is of high-quality and will deliver on every aspect of your coffee needs!

The type of grinder you choose will impact the quality of your brewing, as well as the quality of your drink. So, consider your budget, space and preferred method of brewing before making your decision.
Burned Grounds
Blade grinders use sharp blades to grind the beans. The blade spins at high speeds, like a blender. As the blade moves at a rapid pace it produces heat that can cause a fire to the grounds of coffee. These particles will ruin the taste of your coffee and aren’t suitable to brew.
A top-quality coffee experience requires an even distribution of particles for optimal flavour extraction during the brewing process. Because a blade grinder breaks up the beans into varying size pieces, large and small, it’s impossible to get this level of consistency. A burr grinder however can ensure an even distribution of particles that is reproducible over many types of brews.
While the benefits of a grinder with blades include its low cost and speedy execution, its main disadvantages are that it creates heat when used, causes irregularities in the size of the grind, and has no control over the final particle size. There are ways to improve results with this type of grinder despite its inherent limitations.
When used with a burr mill, the user is able to easily adjust their desired ground size by adjusting the distance between the discs. This allows them to extract the flavor they desire every time from their favorite roast beans. However, making a great brew with a blade grinder requires a lot of trial and trial and.
An angle grinder is a powerful tool that should be used only by qualified personnel. It can cause grinding burn when it is used improperly. This can cause localized changes to the surface of the metallographic material. This can lead to cracking, which should be checked. If not, it could lead to teeth fracture and macropitting.
Grinding burn can result from a variety of reasons, such as excessive grinding pressure or insufficient cooling. It can be caused by inadequate operator training. Wear the correct safety equipment when using an angle grinder. This includes safety glasses as well as a face shield and stainless steel coffee grinder electric toe boots. This will stop any sparks of heat from flying off the tool and hitting people or equipment near by. The sparks can reach temperatures as high as 3,600 degrees Fahrenheit and are capable of burning through materials such as paint or even metal.
Brew that isn’t great.
A blade grinder chops up your beans in a random fashion and leaves you with ground which are of different sizes. The unevenly sized grounds are extracted at different rates in your coffee maker which results in a bitter or weak cup of coffee. The issue is that it ruins the balance that makes for a great cup of coffee. Soluble compounds in your beans are removed over time, which creates the flavor that makes your coffee delicious.
You’ve probably heard that using a burr mill instead of blade mills is the best method to make an excellent brew. Many people don’t understand what a burr grinder does. They buy the cheap blade grinders that are difficult to control and can buy at supermarkets and places that are kitchen-like.
The grinders that are available for sale are essentially a two-pronged blade that is at the bottom of an enclosed chamber. It spins rapidly and chops anything it touches including your beans. The blade is activated by pressing the button. It then chops your coffee beans into different size pieces. The smaller pieces drop to the bottom and are chopped again, while the large pieces remain at the top of the chamber. This results in uneven grounds that are hard to measure accurately – which is the reason you can’t be certain of the amount of ground coffee your grinder made.
These grinders could also burn your beans and ruin the coffee. The heat also removes some of the flavor of your beans, and you’re left with a bland cup of coffee.
If you’ve grind your own coffee with a blade grinder and you’re ready to get rid of it and upgrade to something better. A burr mill can do the job at a fraction of the cost, and will produce an even better result. It’s worth it. Try a manual burr mill like the Rhino Hand Grinder if want greater control over the brew. These grinders feature burrs but are powered by a crank, which provides more control than a plug-in or electric coffee Bean grinder grinder.
