Timemore Sculptor 078S - elektrický mlýnek na kávu na espresso

The large, unmissable adjustment wheel on the front of the grinder is equipped with 50 setting options. These are also completely stepless, allowing the grinder to be adjusted very precisely.
The setting options are really incredibly versatile and the grinding results are perfectly consistent. The fine settings can be reproduced very well. You can also change the zero point of the mill further if, for example, the fine gradations are not enough. To do this, unscrew the front grinding disc and move the grinding disc suspensions anti-clockwise in the specified steps.

Our experience of the grinding level depending on the preparation method with the Sculptor 078S is as follows:
Espresso: 2-10
Mocha: 10-25
Pour over: 25-35
French Press: 35-45
As always, the settings can of course depend on many factors and it is important to familiarize yourself with the grinder.

Important: Please unplug the appliance before cleaning!
To clean the grinder, first remove the bean container. This is attached to the grinder with two small screws. Then you can carefully remove the last residue from the grinder with a brush or carefully vacuum it out with a vacuum cleaner. Then remove the grinder cover, i.e. the adjustment wheel and the metal disk behind it. Behind this are the attachments for the two grinding disks. Carefully remove these and clean them with a dry brush or the vacuum cleaner. Then put everything back together.
Another important note: Do not use water or other liquids to clean the grinder as this may cause damage.

The Timemore 078S grinds impressively fast and can grind 21g of coffee beans in just 10 seconds, although the grinding speed can be influenced by factors such as the grind size and the type of bean.

The mill has the following dimensions:
- Height: 30cm
- Width: 12cm
- Depth: 26.3 cm (required space including Schuko plug)
- Weight: 7.9 kg (measured)

Since this is a single dosing grinder, the size of the bean container is kept quite small. Especially because the focus is on espresso. You can fit a maximum of 30g of beans in it and put the lid on. Grinding works best with quantities of up to 22-25g, which is easily enough for double espressos.
And on top: For all those who would like more volume, Timemore will soon be offering a replacement hopper.

The grinder has a brushless motor, which is quieter than conventional grinder motors. The noise level of the grinder also depends on the speed, the degree of grinding and the amount of coffee. The average noise level of the grinder at a speed of 1400 rpm is just over 70 dB.

To put it in the words of the coffee makers: 18in - 18out, 18in - 18out.
This is also the answer to the question about dead space: it is virtually zero during operation.
Basically, anything where individual coffee particles remain in the machine during the grinding process is referred to as dead space, such as in screw holes, between grinding discs, or in the channels that transport the beans from the hopper to the ground coffee container.
Initial measurements showed a dead space of 0.1gr.
Important: To measure the dead space, the Timemore Sculptor's knocking mechanism was always used, as intended. This removes any remaining ground coffee in the grinder's ejection slot.

The speed can be adjusted between 800 and 1400 revolutions per minute (RPM). We have found that the influence of RPM on the grinding result is barely noticeable or minimal. However, experimenting with the speeds is an interesting way to fine-tune even further. Our team prefers to use the grinder at 1400 RPM, which keeps the grinding to a minimum.

The main difference, as the title of the mill suggests, is the size of the flat burrs installed in the mills. One is 64mm and the other is 78mm.
Both grinders are specialized in espresso preparation.
With a maximum output of 400 watts, the motor of the 078S is a lot more powerful than the 150 watt motor of the 064S.
In terms of speed flexibility, the 078S also offers a maximum of 200 revolutions more than the 064S at 1400 rpm.
In terms of workmanship, the two grinders are not that different, but the more compact dimensions and lighter weight of the 064S alone make it seem like the little sister next to the really high-quality 078S.
