Exactly how coffee grinder works is very simple. You will find that coffee grinders are really common household items and you can even find them as you are walking down the aisle of your favorite grocery store. It is a very popular home appliance that is often associated with the making of espresso beverages.
So if they are so popular why are you just searching for how they work? You’re new to the coffee drinking world or you are done with instant coffee– welcome, why did you wait so long?
Even coffee shops admit that homeowners who grind their own coffee beans to make their household coffee will enjoy their homemade coffee much more. Depending on the type of grinder you purchase and the quality of the grinder you have the ability to grind your coffee from a very coarse grind to a very fine grind.
So when you grind your coffee yourself you will have the added benefit of being able to select just the perfect grounds for your preferred cup. Traditional coffee makers work best with medium to fine grounds.
If you have an espresso maker then you will want to use grounds that are fine with a salt like consistency. If you are using a vacuum brewer or a percolator a coarse grind is what you should be trying to achieve.
Types of Coffee Grinders
There are two main types of coffee grinders – blade grinders and burr grinders.
Blade grinders are typically the type of grinders you find in most homes especially those that have had their grinder for years. These have metal blades that rotate and chop up the coffee beans much like a blender.
You control the size of the grounds in a blade grinder by the length of time the beans are left grinding.
Burr grinders feature metal plates with grooves in them and allow for a wider range of grind sizes. One of the plates remains stationary while the other moves.
The grind size can be adjusted by changing the distance of the plates from each other. There are notches that allow you to change the distance in small increments so you can have more options for grind sizes than you would have in a blade grinder.
This type of grinder will allow you to have more control over your grind size and will allow for a more uniform end product no matter what grind size you set it at.
Then you will find two different types of burr grinders; those with a flat wheel and those with a cone shaped wheel. Those with cone shaped wheels grind more slowly and will have fewer clogs.
Conical burr grinders since they grind more slowly will create less heat and static and as such will not alter the taste of the beans while other grinders that grind faster will cause a bit of a bitter taste.
Then you will find that grinders work in two different ways; you can find manual grinders as well as you can find electric grinders.
This type of grinder features a hand crank, it is by moving this crank that the coffee beans are ground. It will typically take you around 3 minutes to manually grind enough coffee grounds to complete your morning brew.
If you are a little old fashioned or just prefer the extra time and work this will be something that you can appreciate. Many people swear by it that manually ground coffee tastes better than electrically ground coffee. Maybe you could try it and see for yourself.
This type of grinder is the most popular type available. They tend to be small and very affordable and make quick work of grinding your coffee beans.
If you want to make your coffee each time from fresh grounds this is the type of grinder you want to get.
How coffee grinder works is simple – these machines basically chop or press the coffee beans turning them into a powder. There are many small and inexpensive models on the market ranging from $20 to over $100.
