Coffee Grinder: 9 Key Considerations for Industrial and Commercial Use

June 4, 2024

In the bustling world of coffee businesses, precision matters. From espresso shots to pour-overs, the grind consistency directly impacts flavor, extraction, and customer satisfaction. That’s where industrial and commercial coffee grinders step in.

In this guide, we delve into the critical factors to weigh when choosing the right grinder for your establishment. Whether you run a café, roastery, or restaurant, understanding these nuances ensures a seamless coffee experience.

1. Grinder Degree or Size: Coffee Type.

The type of coffee you plan to serve is a primary factor in choosing the right grinder. Different brewing methods require specific grind sizes.

The grind size directly impacts flavor extraction. Most commercial grinders allow you to adjust the grind size to match different brewing methods:

Level	Size (mm)	Recommended Use
Extra Fine	< 0.1	Turkish coffee
Fine	0.1-0.2	Espresso
Medium-Fine	0.2-0.4	Pour-over coffee or espresso machines with a pressurized portafilter
Medium	0.4-0.6	Drip coffee makers with a cone-shaped filter or for pour-over coffee
Medium-Coarse	0.6-0.8	Pour-over coffee or drip coffee makers with a flat bottom filter
Coarse	0.8-1	French press coffee, as it allows the coffee to steep for a few minutes before being pressed
Extra-Coarse	> 1	cold brew coffee, as it allows the coffee to steep for a long time without becoming too bitter

2. Grinder Capacity

Grinder capacity is determined by the size of the hopper and the doser. The hopper holds the coffee beans prior to grinding, while the doser refers to the compartment where the ground coffee is stored before being dispensed.

Hopper Size: Small grinders for home use or low-volume cafes may have a hopper capacity around 1 pound of beans, whereas commercial models for high-volume establishments can hold up to 10 pounds. Larger hoppers reduce the frequency of refilling, making them ideal for busy environments.

Doser Capacity: The doser capacity impacts how much ground coffee is available for immediate use. Dosing grinders typically hold about 6-7 grams per section. In a high-volume environment, this ensures that baristas have a steady supply of freshly ground coffee ready for brewing, which improves efficiency and minimizes downtime.

3. Style: Burr or Blade Grinder

Choosing the right style of grinder is essential for achieving consistent coffee quality. The main styles are burr grinders and blade grinders:

Burr Grinders: Preferred for their precision and consistency, burr grinders use two rotating surfaces to crush the beans into uniform particles. They come in flat and conical varieties:
- Flat Burrs provide a uniform grind size, making them ideal for espresso which requires fine consistency.
- Conical Burrs are versatile, accommodating various grind sizes from coarse to fine, suitable for different brewing methods.

Blade Grinders: These use a spinning blade to chop the beans, leading to inconsistent grind sizes. They tend to create a mix of powder and chunks, and their heating during operation can affect the coffee’s flavor. Thus, they are generally less suitable for high-quality coffee drinks.

4. Dosing or Non-Dosing Grinder

Depending on your specific needs, you may opt for a dosing or non-dosing grinder:

Dosing Grinders: Feature a compartment that stores ground coffee and releases fixed portions at a time. These are ideal for environments where speed and consistency are paramount, such as busy cafés. Dosing grinders dispense ground coffee with the pull of a handle into predetermined sections, ensuring each dose is consistent.

Non-Dosing Grinders: Also known as on-demand grinders, these grind beans directly into the portafilter or a container as needed. This style ensures maximum freshness by minimizing the time ground coffee is exposed to air, maintaining the coffee’s aromatic qualities.

5. Durability

The durability of a grinder is influenced by its build quality and the materials used. Burr grinders, particularly those with stainless steel or ceramic burrs, are recognized for their longevity and resilience:

High-End Burr Grinders: Built for intensive use, these grinders, especially low-speed direct drive models, handle heavy loads without bogging down. They are suitable for both home and light commercial use.

Maintenance: Proper maintenance, including regular cleaning and timely replacement of worn parts, extends a grinder’s life. For high-volume cafes, investing in a grinder built to withstand heavy use is essential to prevent downtime and maintain consistency.

6. Maintenance and Cleaning

Regular maintenance and cleaning are vital for maintaining the performance of your grinder and ensuring the quality of the coffee produced. Over time, coffee residues and oils can accumulate within the grinder, affecting both its efficiency and the flavor of the coffee. Here’s how to keep your grinder in top condition:

Removable Parts: Look for grinders with easily removable parts such as the hopper, burrs, and doser. This facilitates thorough cleaning and prevents residue build-up. Removable parts can typically be cleaned with warm water and a mild detergent or using cleaning solutions recommended by the manufacturer.

Regular Cleaning: Burr grinders require periodic cleaning to remove coffee residues and oils that can cling to the burr surfaces. Use a soft brush, a vacuum, or cleaning tablets specifically designed for coffee grinders to clean the burrs. This prevents stale coffee residues from contaminating fresh grounds.

Scheduled Maintenance: Follow the manufacturer’s guidelines for routine maintenance. This may include lubricating moving parts, checking for wear and tear, and replacing burrs after a certain period or usage amount. Regular maintenance ensures your grinder operates smoothly and prolongs its lifespan.

Non-Dosing Grinders: These grinders may be easier to clean as they do not have multiple compartments that can trap coffee grounds. Cleaning involves simply running a brush or vacuum through the grinding area and hopper.

Dosing Grinders: Although dosing grinders have additional compartments that require cleaning, proper cleaning practices can prevent coffee residues from affecting flavor and grinder performance.

Low-Speed Grinders: These grinders generate less heat and static electricity, which can attract coffee particles and make cleaning more frequent. Less heat means fewer oils burning onto the burrs, reducing the frequency of deep cleaning needed.

7. Price

The cost of commercial coffee grinders varies significantly based on features, capacity, and brand reputation. Here’s how to navigate the price range:

Blade Grinders: Generally the most affordable, but they lack the precision and consistency needed for high-quality coffee.
Burr Grinders: These grinders have a broad price range. High-speed models are more affordable but can generate heat and static, which can affect coffee quality. Low-speed and direct drive models, while more expensive, offer superior build quality, durability, and better control over grind size.

Balancing your budget constraints with business needs is crucial. Investing in a high-quality grinder may have a higher upfront cost but can save money in the long run through durability and consistency, enhancing your coffee quality and customer satisfaction.

8. Type of coffee Grinders and its applications

Each type of coffee grinder caters to different operational needs and customer expectations. Selecting the right type is essential for optimizing workflow and quality:
