Hmm.. That's better still. And a couple of tennis balls in there to press the centre.


Don't pour to fill point. Get close and then squeeze it.But some ideas for "modifications" do emerge from the exercise: The filling wants some plumbing so when the cube is full you don't continue to pump hot wort over the floor
You might not be seeing the implications of what I'm doing to these cubes. You can't "squeeze" them because they have been prevented from bulging out. There's not much to squeeze, and the tackle wrapped about them would make such an operation awkward.
Not quite so predictable! The pump (it's a Grainfather G70) appears (guessing, I'm not taking it apart!) to have a close fitting, possibly flexible, impeller. To make it more effective for its size? But it's capable of holding a very small bit of backpressure, such that the "built-in" sight-glass can show 0 litres on minute and 2-4 the next (the G70 pumps out via the sight glass). I'll need to get a better measure or figure a work-around.PeeBee wrote: ↑Mon Oct 23, 2023 12:41 pm... It was filled with 22 litres, give or take a couple hundred milliliters, at about 90°C (some heat is lost during filling, so don't expect 100°C to be going in). 84°C represents 1% shrinkage, so cooled to ambient the sealed cube now holds (a further 3% shrinkage, four in total) about 21.34 litres. That's a bit more predictable! ...
I hear you. I also hate taps. Generally in the wrong place and filth traps and leaky drippy bollox.
Now here again... we come down to good design or designer who doesn't know the first thing about the product usage.
