What kind of knock boxes are available?

Every single time when you make a espresso you will get waste from the coffee puck. As a professional barista in a coffee bar/restaurant you want to get rid of these old compacted coffee grounds as`fast as possible. The easiest way to do is to knock the coffee puck out of the portafilter against a knock bar.

All the knock boxes have 1 item in common and that is that they use a knock bar. This is in almost every case a metal tube or bar, where a rubber is moulded or installed around. These do wear out that’s why they are easy to replace.

There are a variety of options and solutions for various applications, how much space do I have? Is it for a commercial or a domestic setting? How much coffee waste am I going to produce during the day, is it easy to clean? Do I want a electrical or manual knock box?

 

Knock box drawer


The most well known and oldest type of knock box is the pull out drawer. This type of knock box is normally installed in the cupboard underneath/next to the espresso machine. When you want to get rid of your coffee puck you only have to open and close the drawer. These drawers are made by 2 Italian companies. Ronda and Priolinox.

But you also have tilt drawer, this drawer only opens partially open and can be easily closed again. these models are only made by Ronda.

The choice of this type is mainly in commercial applications, seen the amount off coffee residue these drawers can hold
