Mr. A. P. Hayne describes and illustrates a wine-cooler of ingenious 

 design, which should prove of great service to wine-makers in hot 

 countries. In its construction and working, drip, spray, and blast 

 are happily brought into play together, with the result that a con- 

 siderable reduction in the temperature is obtained at the expense of 

 a small volume of water. The apparatus consists of the cooler 

 proper, made of two batteries or columns of thin copper tubes, 

 somewhat flattened, as shown in the illustration. These tubes, 

 which are five and a-half inches wide by one and a-half inches, run 

 continuously, as in the case of the Muntz and Rousseaux apparatus, 

 and are held by bronze castings fastened by thumb screws over 

 rubber washers, for the convenience of cleaning. In order to secure 

 the best utilisation of the spray, and as little waste of it as possible, 

 the two sets are placed as near together as practicably possible ; and 

 experiment has demonstrated that, for this purpose, they should be 

 set one inch apart in the inverted V (A) position at an angle of 

 about 30 degrees. 



The wine enters A, rises in the tubes, and from C overflows 

 and is carried to the bottom of the second set, which faces the 

 blower; there it ascends, and from B it is best carried to a storage 

 tank at a greater elevation than the fermenting vat, to which it is 

 returned by gravity when a sufficient amount of it has been cooled, 

 thus avoiding any waste of energy by pumping the same wine twice 

 through the cooler. Underneath the cooler is a water-box, for 

 collecting the drip from the tabes. This cooler frame is connected 

 with the blower by means of a pyramidal canvas sleeve, about five 

 feet long, which prevents loss of blast and spray. In order to 



Blower. 



prevent the unequal distribution of the blast, which would be- 

 stronger at the circumference than in the middle, a cylindrical sleeve 

 three and a-half feet long is interposed between it and the blower.
