  • Venturi pipe for flow measurements

    Venturi pipe for flow measurements

    , ,

    As we were going through the brewery’s hose system and replacing the sanitary valves, we also found the need to upgrade our flowmeter to a larger size. We started from the same theory as the previous version but made it more robust and, most importantly, designed it for higher flows. With the old venturi pipe,…

  • Cleaning adapter for the sample coil

    Cleaning adapter for the sample coil

    , , ,

    We think that flushing the Brewtools sample coil after taking a sample is kind of messy and designed and printed this little accessory for it. It is printed in Formlabs Surgical Guide SLA resin that is kind of food grade and can handle the temperatures. CAD-files for printing your own adapter (NOTE not for commercial…

    Pending an NDA (non disclosure aggrement) with yyy.. can’t say more right now 😉

  • Grain conditioning experiments

    Grain conditioning experiments

    , ,

    At the beginning of our career as brewers (about 2 years ago) we experimented with conditioned grains to boost the efficiency of our brewery (which was really rubbish). In those days we used steam which we forced through the grains, this worked well for the efficiency of the brewery at the time but the process…

  • Electronic spunding valve

    Electronic spunding valve

    , , ,

    We have thought about building an electronic spunding valve for a while. We have measured pressure accurately and logged it to a db for a long time now but used a manual spunding valve. When planing for a brew we realized that the spunding would fall during a vacation out of town and that triggered…

  • Volume sensor for the fermenter (from weight)

    Volume sensor for the fermenter (from weight)

    , , ,

    The differential pressure based volume sensor is kind of tricky to use and have a lot of “moving parts” so we designed a volume sensor based on the fermenter weight instead. The scale is a standard bathroom scale capable of 180 kg that is stripped of all electronics except for the 4 pressure sensors that…

  • Volume sensor for the fermenter (from differential pressure)

    Volume sensor for the fermenter (from differential pressure)

    , , ,

    Knowing the “exact” wort volume in a fermenter is “crucial” for quality control during the brewing process. However, measuring the volume accurately and continuously can be a challenge. At our brewery, we use differential pressure sensors for various measurement tasks, and we realized that this technology could also be used to estimate the wort volume…

  • Digital pressure sensor for the fermenter

    Digital pressure sensor for the fermenter

    , , ,

    Everything we do is connected 🙂 The pressure sensor of the fermenter is no exception. We used the same typ of sensor as for the Venturi pipe and suction sensor but with a greater range (6 bar) and not differential.It is read from the fermenter controller, i.e., the RPi controlling the glycol chiller and other…

  • Digital “suction” sensor

    Digital “suction” sensor

    , ,

    Many brewers use manometers or clear hoses at the bottom of the MLT to monitor the pressure below the grain bed. We have taken it to the next level and put a differential pressure sensor (1 psi range) between the bottom and top of the MLT to be able to digitally monitor and log the…

  • Temperature sensor system

    Temperature sensor system

    , ,

    We use six temperature sensors in the brewery for measuring the We use 1.5″ thermo wells for HLT, mash bottom and boil, and custom built sensor probes for mash inlet and outlet (after cooler).The reason for using custom probes is that the thermo wells ads latency to the measurement system that is not desirable for…

  • Venturi pipe for flow measurements (OLD)

    Venturi pipe for flow measurements (OLD)

    , ,

    This system is now updated with a bigger version! We started with a traditional flow sensor with an impeller but it was not accurate enough and was kind of invasive, especially when there was grains stuck in the impeller 🙂 Being physicists at trade we remembered something about differential pressure over a narrowing of a…

  • Orbital shaker for degassing SG samples

    Orbital shaker for degassing SG samples

    , ,

    When we invested in an EasyDens SG meter we started to investigate the best way to degass samples for it and found many articles referencing orbital shakers. So, lets build one! Using a microcontroller (Arduino), a stepper driver board and a small stepper motor the following was produced with the help of 3D-CAD (Solidworks), a…
