How to choose a coffee grinder?

Things to consider when buying an industrial-sized coffee grinder

If you’re a coffee roaster, investing in an industrial-size coffee grinder is essential to ensure consistent quality and efficiency in coffee production. However, with many options available in the market, how to choose a coffee grinder that is the right one for your needs, can be difficult. In this article, we’ll guide you through the key factors to consider when choosing a coffee grinder as a coffee roaster.

Capacity

The first thing to consider when choosing an industrial-size coffee grinder is its capacity. The capacity of the coffee mill will depend on the volume of coffee you’re producing and the grinding degree. Look for a grinder that can handle your production volume without causing bottlenecks in the production line.

Grind quality

The grind quality is critical to the flavor and consistency of your coffee. You’ll want to ensure that the industrial-size coffee grinder produces a consistent grind size. Look for a grinder that can make a range of grind sizes, from coarse to fine, that is to say, cater to different brewing methods.

Durability

An industrial-size coffee grinder is a significant investment, so choose a durable and reliable machine. Look for coffee mills made from high-quality materials that can withstand the rigors of heavy use in a production environment. Evaluate the durability of the motor, the grinding burrs, and the overall construction of the machine. Also, be sure that the grinding doesn’t heat the coffee beans. Cooling is, in most cases, necessary to ensure the uniform quality of your coffee.

Maintenance and cleaning

Regular maintenance and cleaning are essential to keep your coffee grinder in good working condition and to prevent contamination of your coffee beans. Look for a grinder with a design that makes it easy to clean and maintain, with easily removable parts that can be cleaned and sanitized regularly. The coffee grinder should come with maintenance instructions and recommended maintenance schedule.

Price

Finally, you’ll need to consider the price of the coffee grinder. The cost of these machines can vary widely depending on their capacity, features, and construction. Look for a coffee mill that fits your budget while still meeting your needs for production volume, grind quality, durability, and ease of maintenance.

How to choose a coffee grinder and determine your grinding degrees?

“Grinding coffee beans produces fresh grounds, and the coarseness of the grind determines the resulting size of the coffee granules. The term “grinds” specifically refers to the size of the granules, rather than the granules themselves. For instance, a coarse or medium grind refers to the size of the coffee granules produced, rather than the coffee granules themselves.”

Grinding degrees of the coffee grinder

There are several different coffee grinding degrees or settings that you can use when grinding coffee beans. Here are some common ones, listed from finest to coarsest:

1. extra-fine: < 0.1 mm

This grind is very small, similar in size to flour or powdered sugar. It’s often used for Turkish coffee, as it allows for a very strong and concentrated brew.

2. fine: 0.1-0.2 mm

This grind is about the size of granulated sugar. It’s commonly used for espresso machines with a non-pressurized portafilter, as it allows for a slower extraction time.

3. Medium-fine: 0.2-0.4 mm

This grind is a bit smaller than medium, similar in size to fine sand. It’s often used for pour-over coffee or espresso machines with a pressurized portafilter.

4. Medium: 0.4-0.6 mm

This grind is about the size of table salt or sand. It’s commonly used for drip coffee makers with a cone-shaped filter or for pour-over coffee.

5. Medium-coarse: 0.6-0.8 mm

This grind is a bit smaller than coarse, similar in size to rough sand or kosher salt. It’s often used for pour-over coffee or drip coffee makers with a flat bottom filter.

6. Coarse: 0.8-1 mm

This grind is a bit smaller than extra-coarse, similar in size to sea salt or even coarse sand. It’s commonly used for French press coffee, as it allows the coffee to steep for a few minutes before being pressed.

7. Extra-coarse: > 1 mm

This grind is very large and chunky, similar in size to peppercorns or even larger. It’s often used for cold brew coffee, as it allows the coffee to steep for a long time without becoming too bitter.

Please note that these are approximate particle sizes and may vary slightly depending on the grinder and coffee bean used. It’s also worth noting that coffee grinders may have different settings or measurements for these grind sizes.

Each of these grinding degrees has its best use case depending on the brewing method and the type of coffee you’re making. For example, French press coffee is best made with a coarse grind, while espresso requires a very fine grind. Experiment with different grind settings to find the perfect one for your brewing method and taste preferences.
