ACM Praktika Semi Joysteam portafilter machine

Please note: Some manufacturers test their coffee grinders before shipping, which means that small coffee residues or bean residues can occasionally be found in the grinder. This procedure is used to test functionality and is considered a quality feature. Of course, we only sell new products - unless expressly stated otherwise.

With some coffee grinders, the ground coffee can become statically charged and spray out of the portafilter at the side. This means that not all of the ground coffee gets into the portafilter, which can lead to uneven extraction. Our recommendation: Use a dosing funnel to ensure that all of the ground coffee is precisely fed into the portafilter - for optimal espresso enjoyment.

Conventional coffee grinders often leave a so-called dead space in which coffee residues accumulate. These residues can not only affect the freshness, but also lead to old and fresh coffee grounds being mixed, which negatively affects the taste. In contrast, single dose grinders have a well-thought-out design that eliminates the dead space. Each portion is ground individually and precisely so that no residues are left behind - for a consistently pure and full-bodied coffee experience.

When choosing the right portafilter for your portafilter machine, it is important to know that each manufacturer develops its own brewing group - the most well-known is the Faema E61. However, this does not mean that any portafilter will fit without any problems. An incompatible portafilter can leak, which will have a direct negative impact on the quality of your espresso. We therefore recommend using either the portafilter originally supplied or one that is explicitly stated to be compatible with your machine. This will ensure that the pressure is optimally built up and the espresso is perfectly extracted.

Yes, of course, you are welcome to come by and look at our products by appointment. We would be happy to advise you personally. The best thing to do is to send us an email with a few suggested appointment times.

We are located 5 minutes from the motorway between Stuttgart and Lake Constance on the edge of the Black Forest.

Another little tip for the perfect start with your new mill:

You will get the best grinding result after you have ground about 1-2 kg of beans. It is best to use a few cheap beans so that the grinder can work optimally. And if you are wondering what you can do with the bean flour - it is perfect plant fertilizer! 🌿

It contains nitrogen, potassium, sulfur and phosphorus and is a real nutrient bomb for your plants.

Det finnes flere argumenter mot offset-kalibrering på Lelit-espressomaskiner, spesielt på modeller som Lelit Bianca. Disse handler hovedsakelig om kompleksiteten og begrensningene ved å bruke offset som eneste løsning på temperaturproblemer:

1. Temperatursvingninger og ustabilitet. Offset tar utgangspunkt i en konstant forskjell mellom kjelens temperatur og bryggetemperaturen. I praksis kan det imidlertid oppstå temperatursvingninger, for eksempel ved lengre pauser eller kontinuerlig brygging. Derfor er den faktiske bryggetemperaturen ikke alltid nøyaktig forutsigbar.
   
2. Avhengighet av omgivelsesforhold. Faktorer som romtemperatur, luftfuktighet og maskinens tilstand (for eksempel oppvarmingstid) påvirker bryggetemperaturen betydelig. En fast offset kan ikke automatisk kompensere for disse variablene, noe som kan føre til unøyaktige resultater.
   
3. Varme­tap ved pauser. Etter lengre oppholdstid kjøler bryggehodet seg ned, og maskinen trenger tid for å nå ønsket temperatur igjen. En riktig innstilt offset kan ikke kompensere for dette, derfor er ekstra tiltak som en «cooling flush» nødvendig.
   
4. Feilkalibrering fra fabrikk. På noen Lelit-modeller har det vist seg at offset-verdien ofte er feil innstilt fra fabrikk (for eksempel 4–8 grader for lavt på Lelit Bianca). Dette krever manuell etterkalibrering av fagpersonell, noe som kan være komplisert for sluttbrukeren.
   
5. Misforståelser i bruk. Mange brukere blir usikre på grunn av motstridende informasjon om offset-innstilling, noe som kan føre til feiljusteringer. For eksempel forventes det ofte at offset alene skal løse alle temperaturproblemer, selv om det bare er én del av et mer komplekst system.
   

Konklusjon
Offset-kalibrering er et nyttig verktøy, men bør ikke vurderes isolert. En kombinasjon av presis PID-styring, regelmessig vedlikehold og tilpassede teknikker (som skylleskudd) er nødvendig for å oppnå optimale bryggeresultater.
