Hi, I am after a price on a custom machine. I have attached a photo of it, I haven' T got fine details yet, but it is going to be a hops addition machine to beer. I need the hopper to be about 500mm tall and 400mm diameter, feeds down into the diaphragm pump, which then goes into a 1.5" Tube that has beer running through it, it needs to have a static spiral mixer (bottom row second from right photo) installed in the 1.5" Tube to combine the hops and the beer. Is this something you can do, and what is the rough price including shipping to Australia
