    Dedicated Herms Guide, Problems And Solution Thread

    Hi everyone, OK - I've got it now, and realised my stupidity - of course you can't raise the mash temp if you don't have a differntial between the HEX and the mash temp... well duh I've drawn up a not to scale diagram to get my head around all the connections and the way it would work - think...

    Dedicated Herms Guide, Problems And Solution Thread

    Thanks for the comments and ideas. So when it comes down to it, it seems there are two main ways to control/run a herms system. 1. Hex a fair bit higher than target step temp, 10 deg or so controlled by a thermostat, and the flow rate of the pump controlled via probe in the hex outlet to...

    Dedicated Herms Guide, Problems And Solution Thread

    Great thread/ideas/discussion - this has helped me a lot. So, in the redesign of my post flood brewery, I'm planning to make it a herms capable system, either running that way from the start or as an upgrade down the track - depends on how the $ all pan out. The main thing I'm trying to work...

    Herms Design Advice...

    Thanks everyone - sounds like its pretty clear cut - smaller HEX vessel it is then. What are peoples thoughts about putting thermowells in the mashtun and HEX vessel - are they both needed? I like the manual control of the brewery (its part of the process I enjoy), so can't see myself ever...

    Do You Filter Your Beer Through Fish?

    Ross - this may or may not help... From "Principles of Brewing Science" by George Fix: "[Chill] haze involves complexes of high-molecular-weight proteins and polyphenols (tanins). These compounds form weak, temperature-sensitive hydrogen bonds that are broken as the beer's temperature...

    Mixing Water & Temperature Calculations

    http://www.sugartech.co.za/heatcapacity/index.php There we go - on online calculator for specific heat capacity of sugar solutions based on published engineering tables. As it turns out, at low concentrations, the spreadsheet in its current form is pretty close at getting the Specific Heat...

    Mixing Water & Temperature Calculations

    I'm sorry - I have to correct a couple of mistakes here. 1. Heat capacity is the amount of heat to raise anything by 1 degree (or K). You are talking about specific heat capacity when you raise 1g of a substance by 1 degree (or K). 2. Water has a specific heat capacity of 4.184 J/g/K not 1...

    LOL - it was very funny - I was tellying my wife how close it was to working, and relayed the couple of suggestions - and she says - "you keep complaining its hard to move, why don't you just put wheels on it and solve all the issues?!" She's a clever one! Talk about state the obvious! M
