    Insulation of the kettle?

    I was inspired a bit by this post: Recirculating BIAB setups | Craft Hardware for me it made a lot of sense.

    Insulation of the kettle?

    Thanks - I get your point, but still I have all those opportunities as well if I like to go this path? Perhaps the 400 micron bag is too of a wide mesh for real fine crushing so that perhaps was a useless purchase with your approach - again I have only a cheap monstermill so I dont expect so...

    Insulation of the kettle?

    Hello and thanks for input. I was thinking that re-circulation would improve the clarity (not a native english speaking person so perhaps wording issue here) of the wort and also allow me to have heat steps in the process. The bag I purchased is a 400 micron, what should be a reasonable setting...

    Insulation of the kettle?

    Hello, I have a 15 gallon pot (70 litres) an plan to brew 5 and 10 gallon batches. I will recirculate the wort and have heating elements below the false bottom under the bag, temperature probe will be at the top of the kettle (in the lid inlet) Is there normally a need for insulation of the...

    Temp measurements in circulating BIAB

    Thanks for your comments. I will move the probe to the kettle outlet. the diameter of the kettle is about 17", will it be likely that the wort will "channel" from the bag down to the outout and not "equal out"? I dont plan to stir very much during the mash- o perhaps I should? rims or herms I...

    Temp measurements in circulating BIAB

    Okey - thanks. It was other temp probes I used, I have only one PT100 (3-wire model), the other was a temp meter with a typk k thermocouple and I also tested with a kitchen thermometer (Inkbird). I tested those the other day with a DS18B20 (connected to a Raspberry Pi) in a kettle from 20°C...

    Temp measurements in circulating BIAB

    The PID is a MC901 with a PT100 sensor. The other reading I get is about 62-64 in the wort when I put a probe in it and as low as 58-59 in the space between the pot walls and the "grain bucket". the spade around the bucket is quite big - 5-6 cm's on each side - perhaps this is what makes the...

    Temp measurements in circulating BIAB

    I am using two heat elements on 2.2kW inside the pot. I connected the heater elements to a PID and settled the temp to the wanted mash temp (67°C). So I have a pump fed from the outlet valve on the kettle and pumping up to a nozzle under the lid. In the lid I measure the temp and if it's <67°C...

    Temp measurements in circulating BIAB

    Hello, I am moving into BIAB and have a 70l kettle (18 gal) and made a trial run with a grain bucket with a mesh in the bottom (made from a old fermenting bucket). I was recirculating the wort with a temp probe in the inlet at the kettle pot lid and also temp probes in the wort (both down below...
