CHAPTER V. 



THE PASTEURIZING COOLER. 



I have shown how in some pasteurizing apparatus the heating, 

 and cooling may be done in one vessel. I have also shown some of 

 those where the same construction is used for both purposes. It re- 

 mains now to mention a few of the coolers which have been used. 



COOLERS WITH EXPOSED SURFACE. 



Among those made on this plan the most effective are undoubt- 

 edly the Lawrence and the Laval. The former has indeed been so 

 thoroughly copied both in Europe and America by most of the man- 

 ufacturers, who thus have paid the inventor a high compliment. The 

 latter is illustrated in the lower part of Fig. 18, and the former in .the 



lower part of Fig. 

 14, and I now 

 show in Fig. 39 

 cross sections of 

 the three differ- 



ent styles of con- 

 structing this 

 cooler, A. B, c. 



To this should be added the 

 cheap tin cooler made in 

 America under the name of 

 Danish Weston cooler, Fig. 40, 

 and the cooler made by A. H. 

 Barber, of galvanized iron 

 pipes, with close elbows and a 

 partition of tin soldered be- 

 tween them. 



The Lawrence style of 

 coolers are made in America 

 by the Star Cooler Manufac- 

 turing Co., Haddonfield,N. Y.,
