Uni tanks are fermentation tanks that can also be used for conditioning, meaning a brewer can ferment and carbonate in a single tank. Even if the brewer does want to transfer the beer, the uni tank is flexible enough to accept beer from either another uni tank, or wort from the brewhouse.
V-Brew uni tanks are fully insulated with a fully welded secondary jacket. No rivets or crevices to harbour rouge microbes. The tanks are also chilled via a jacket on the cone and on the side wall, allowing efficient cooling below the point which the convection currents switch – about 3.5°C.
Uni tanks typically come with a 60° cone for easy yeast harvest and removal, a full discharge and a partial discharge with racking arm assembly, thermowells, hop port, spunding valve and CIP assembly.
Traditionally, beer is ‘brite’ when its clear, but modern beers can move through a brite tank onto packing without clearing at all – a function partly of the grain bill and hop regime. V-Brew brite tanks are used for storage, maturation and carbonation – as well as producing a ‘brite’ beer.
The brite tanks are dished bottomed, making them shorter than a conical tank of the same volume and diameter, and are useful when head height is tight. Its common also to ferment in a V-Brew brite tank, though yeast handling becomes more challenging. They can also be used as cellar serving tanks.
V-Brew brite tanks typically are dished bottomed and cooled using a dimpled jacket, and are insulated with a welded secondary jacket. The tanks are supplied with a carbonation stone, with CIP assembly and with a sample tap.
The V-Brew horizontal brite tanks are a stackable solution, for when a brewer has more floor space than height. They are also common as serving tanks in taprooms, where that can be stacked behind the bar.
The horizontal brites also benefit from a large bottom area, which can be useful when dropping not flocculent yeast. A horizontal tank – especially compared to large cylindroconical tanks – subject yeast to a lower hydrostatic pressure, which can be desirable when certain esters are desired.
V-Brew horizontal brites are insulated and clad with a fully welded secondary skin. They are chilled using a dimpled jacket and are supplied with sample tap, CIP assembly and carbonation stone.
‘Clean in place’ (CIP) sets are designed to make cleaning tanks and vessels easy and thorough. They consist of a wheeled frame with two tanks – one insulated and heated and the other single skinned – an VFD controlled pump and a pipe manifold.
Cleaning solution – generally caustic is heated and then circulated through a sprayball and back to the pump to be recirculated to the sprayball. The pump is VFD (speed) controlled so the flow-rate can be controlled. The heat and flow-rate are both key components to effective cleaning.
The second tank generally contains a sanitising solution, which helps to sterilise the now clean tank.
The hopzilla aims to make dry hopping easier, safer, more efficient and with less oxygen pickup. Instead of loading hops into a fermenter – giving millions of nucleation points and the chance of uncontrollable breakout -the hops are introduced through a second vessel. The hopzilla.
The hopzilla is filled with hops, usually pellets, its pressure is balanced with the FV or CT and the beer is pumped in a loop – macerating hop pellets and increasing aroma yield in the process.
Many brewers find they get up to twice the aroma, or are able to use half the hops.
