Compak Professional Coffee Grinders and Dosing Systems

Compak is a Spain-based manufacturer developing professional grinders for espresso and different coffee brewing methods since 1952. The brand's product program spans on-demand espresso grinders to single-dose systems with 98-millimeter burrs and shop-type grinders with 120-millimeter burrs. Compak coffee grinder prices vary by flat or conical burr, burr diameter, dosing method, grinding range, and whether the device works into a portafilter or a bag.

Compak's portfolio includes the 68-millimeter conical-burr F10 and E10, the 83-millimeter flat-burr F8 and E8, the 64-millimeter flat-burr E6, Bolt 64 and Bolt 83, the 98-millimeter burr PK100, and the R series with 83 and 120-millimeter burrs. The Cube Tamp automatic pressing unit is geared toward standardizing the post-grinding tamp process as a separate station.

How Does the Bolt Series Combine Preloading and Instant Dosing?

The Compak Bolt is a system that combines grinding coffee on demand with fast access to pre-prepared doses in a busy espresso bar, all in one body. The machine can grind a single or double dose directly into the portafilter; it can also keep two coffee doses ready in an internal buffer chamber.

Pre-loaded doses help the barista fill the portafilter without waiting for grind time during a busy order wave. Once a ready dose is used, the machine can grind the next coffee to refill the buffer. This arrangement keeps a limited number of doses ready rather than letting a large amount of ground coffee sit in a classic dosing hopper for a long time.

The Bolt has different working modes combining instant grinding, ready doses, and both systems. A business can run fully on-demand during quiet morning hours and with buffer-dose support during busy service. Mode selection should be defined clearly enough for staff to follow the recipe.

The portafilter-detection system can help recognize the portafilter placed on the fork and start the corresponding dose. Compatibility of single and double baskets, or different portafilter weights, with the system should be tested during installation.

The Usage Difference Between 64 and 83-Millimeter Flat Burrs

The Bolt and E series offer 64 or 83-millimeter flat burr options. A larger burr surface can help grind the same coffee amount in a shorter time and reduce motor run time during busy service. Even so, burr diameter alone doesn't determine cup quality or daily capacity.

The Bolt 64 and E6 OD, in the 64-millimeter flat burr class, are geared toward medium and high-volume espresso bars. The Bolt 83, E8 OD, and F8, with an 83-millimeter burr platform, can be considered for businesses targeting shorter grind time or more intensive use.

Burr geometry, rotation speed, motor power, and outlet channel together affect particle distribution. Two models with the same diameter can have different dosing systems, displays, or cooling arrangements. Comparison shouldn't be made on millimeter value alone.

The Working Structure of the E10 and F10 Conical-Burr Models

The E10 and F10 series use 68-millimeter conical grinding burrs. In a conical burr arrangement, the bean enters between the inner and outer burr from the top and is ground as it moves down in stages. This structure can create a different rotation speed and motor character than a flat burr.

The E10 is geared toward electronic on-demand dosing, while the F10 is geared toward a newer-generation control and adjustment arrangement. Even with the same burr diameter, the two models differ in display, recipe management, and body features. The exact model and version should be confirmed in the quote.

No universal ranking of superiority can be made between conical and flat burrs for every coffee. The barista should test both systems with the bean to be used, the espresso ratio, and the targeted flow character.

PK100 Single Dose and Shop Grinding

The PK100 Single Dose is geared toward processing a single coffee portion over a wide grinding range with 98-millimeter flat burrs. Adding only the amount to be used to the hopper allows switching between different beans and prevents coffee from sitting in a large bean hopper.

In single-dose use, the amount of coffee remaining in the grinding chamber matters. A bellows or air-blowing system can help direct particles remaining on the burr and outlet channel outward. The difference between weighed beans and output ground coffee should be regularly checked.

The PK100 Shop, on the other hand, is geared toward grinding larger amounts for packaging, cupping, or filter prep at a coffee shop. Setting can be switched between methods like espresso, moka, filter, and French press. The outlet area should be cleaned to limit the previous bean mixing into a new package.

High-Volume Bag Coffee With the R120 and iR8

The R series is developed more for shop and roastery-type grinding than portafilter dosing. The R120 model uses a 120-millimeter flat burr, while the iR8 uses an 83-millimeter flat burr. The large burr platform is geared toward grinding a high coffee amount quickly into a bag or collection vessel.

In bag grinding, the package must sit securely at the outlet spout. A scale, bag-sealing, and labeling area should exist next to the grinder. Buying a high-gram bag grinder for an espresso bar alone doesn't cover the portafilter workflow.

Different brewing methods' setting points on a shop grinder should be recorded by the business. Keeping setting names only as "fine" and "coarse" can make it harder for different staff to produce the same result.

Post-Grind Compaction With Cube Tamp

The Cube Tamp applies automatic pressure to the coffee bed in the portafilter with a programmed force. It can help reduce the barista using different tamp pressure on every shot and limit wrist motion during a busy shift.

Although the unit can be used with different portafilter diameters, the basket must be correctly centered under the device. If the pressing surface makes angled contact with the coffee bed, the tamp won't form evenly. The portafilter should be fully seated on the fork, and the device's compatibility measurements should be checked.

An automatic tamper doesn't replace correct dosing and distribution. If coffee is piled to one side inside the portafilter, applying pressure only from above may not even out the entire bed. Grinder output and distribution should be evaluated together with the tamp.

• High-volume bag coffee grinding with the R120 and iR8; a separate automatic portafilter compaction station with Cube Tamp

How Is Bar Flow Set Up for a Compak Grinder?

Espresso count during the busiest 15 minutes and the coffee gram used per shot should be calculated. The grinder's grind time should be evaluated together with portafilter changeover and tamp stages. If the Bolt buffer-dose system will be used, it should be determined during which service period ready doses will be activated.

Main espresso, decaf beans, and filter coffee shouldn't be continuously swapped on the same device. The Bolt or E series can handle high-volume espresso, the PK100 variable beans, and the R series bag sales as separate tasks.

Sufficient space should be left above the grinder for hopper filling, in front for the portafilter, and beside it for the Cube Tamp. Motor air intakes shouldn't be blocked, and access for cleaning the coffee channel and burrs should be available.

Frequently Asked Questions

What is the difference between the Compak Bolt 64 and Bolt 83?

The main difference is grinding burr diameter: the Bolt 64 uses a 64-millimeter, and the Bolt 83 an 83-millimeter, flat burr. A larger burr, with a suitable motor and recipe, can help grind coffee in less time. The decision shouldn't be made on burr diameter alone without testing bar capacity, counter space, and the coffee used.

Does the Compak Bolt let pre-ground coffee sit for a long time?

The Bolt keeps a limited number of ready doses in its internal buffer rather than a classic large dosing hopper, and can grind a replacement as a dose is used. The goal is to provide short wait times during busy service. How long ready doses are kept should be limited according to the business's coffee quality procedure.

What features affect Compak coffee grinder prices?

Price is determined by flat or conical burr, burr diameter, on-demand or single-dose operation, and digital control. The Bolt buffer-dose system, PK100's wide grinding range, the R series' bag capacity, and complementary equipment like the Cube Tamp change the cost. The model should be chosen based on actual service task.
