- Stainless Steel Variable-capacity Tanks for fermentation and storage
Variable-capacity tanks are 'always full' due to the separate pneumatically sealed inner lid which can be set at any height within the tank; during fermentation it is set about 2" above the liquid surface, at other times the lid is lowered to rest on the liquid.
The pneumatic sealing tube is pumped up (to 0.5 bar) with a small hand pump rather like a bicycle tyre pump. When the sealing tubes are new they are a very tight fit, difficult to stretch around the lid. With use they stretch gradually and become progressively easier to fit. A list of tube sizes and prices.
Volume calculations, measurements should be accurate to 0.1 cm :-
1. Before first using a tank:-
a. calculate the volume in litres per cm height = surface area (π
r2, where π
= 3.14159, r = radius in cm) divided by 1000.
b. calculate the total volume in litres = internal height at the side of the tank (in cm) x the volume in litres per cm height;
plus (if the tank has a concave base) the volume of the concave base, measured by pouring in water from a measuring jug.
2. Calculating the volume of liquid in the tank:-
use a tape measure (with the end lowered to touch the liquid surface) to measure
the height of the liquid surface below the top of the tank. Measure down on two
opposite sides, and take an average of the two heights, as the tank may not be
standing quite horizontally. Multiply this average height by the volume in litres per cm height,
and subtract the result from the total volume.
New tanks from four suppliers:-
Vertical cylinders with flat bottom or concave bottom; flat bottom tanks can be stood on a small pallet, which can be moved around with a
pallet-truck. All have an attractive 'marbled' finish'.
Internal cooling plates can be fitted to the lids of all types:-
Prices are for single tanks, there may be a discount for multiple tanks, according to quantity.

In my winery I changed from Speidel tanks to these, I find that the size of the 1000 litre tank is very convenient to work with.

Note: these tanks have a slightly thinner wall than Speidel tanks,
so when a heavy rouser is used through the Gr.37/70-flap-valve the motor of the rouser needs to be supported. Also the KTM Red Wine system for 1000 litre and larger tanks.
