Liq′uid-cool′er.
An apparatus for cooling wort, beer, wine, water, etc. On a small scale, as the wine-cooler at the sideboard, it is a tub in which bottles are stood with broken ice around them.
For soda-water and other liquids on draft, it is a coil of pipe which passes through a chamber, and is covered with pounded ice. For milk, it is a pan which has a false bottom, through which cold water circulates.
For beer on draft, it is a chamber in which the keg is set with blocks of ice about it and the faucet projecting.
See
Fig. 632.

Volute-cooler. |
On a larger scale, used in breweries for cooling wort or beer, it has many forms.
It is usually a very large shallow vat. One is shown in
Fig. 2966. It is a volute, formed by a wide strip of metal set on edge between upper and lower heads.
A long sheetmetal plate is folded and then convolved, so as to form a helix with two distinct spaces; the edges of the plate are attached to the top and bottom disks, which form heads, and one space in the convolution is for the refrigerating liquid, the other for the vapor or fluid to be condensed; induction and eduction passages admit and discharge the respective fluids.

In
Fig. 2967, the beer, on its way from the
coolbeds to the fermenting-tun, flows into the trough
D, and thence trickles over the vertical series of horizontal pipes, through which cold water passes.
Similar to this in construction is the Degrand condenser, except that the latter is for heating cane juice, and the pipes are filled with steam.
See
Fig. 1421.
The cooler in which the wort passes through a coil of pipe in a vat which is filled with ice, or through which flows a stream of cold water, is also like the coil-condenser in the arrangement of its parts.
See
Fig. 631.

Another form is that in which an outer and an inner vessel are filled with ice and communicate by short tubes which cross the intervening space; over these tubes the beer descends in a shower from a pan above.
Fig. 2968 has two vertical cases
A A′ in which wort circulates, discharging at
e and
e′. From each of these cases project boxes
h m, which lap past each other in the intervening space through which water flows from
D to
E. In the cases are also plates which extend into the boxes, so as to form a sinuous channel through which the wort passes in a sheet against the outer walls of the box, which are cooled by the water.
Another form is a series of inclined troughs through which the wort passes to be cooled by exposure to the air.
