CONTINUOUS PROCESS EVAPORATORS 



must be completed before any of the finished product leaves the 

 evaporating vat or tank. The operation in either case is inter- 

 mittent and not continuous. 



Of more recent years, equipment and processes have been 

 developed that make possible continuous operation. That is, the 

 fresh milk enters the machine and the condensed milk leaves it 

 simultaneously and continuously. So far three types of continu- 

 ous machines have been perfected sufficiently to make them com- 

 mercially practical and usable, namely the Buflovak Rapid Cir- 

 culation Evaporator, invented and manufactured by the Buffalo 

 Foundry and Machine Co., Buffalo, N. Y., the Continuous Con- 

 centrator, invented by the By-Products Recovery Co., Toledo, 

 Ohio, and manufactured by the Creamery Package Manufactur- 

 ing Co., Chicago, and the Ruff Condensing Evaporator, manu- 

 factured by The Cream Production Co.. Port Huron, Mich. 



BUFLOVAK RAPID CIRCULATION EVAPORATOR. 



This type of 

 Evaporator has been 

 developed from the 

 standard return-flue 

 tubular boiler and 

 adopted for the spe- 

 cial purpose of han- 

 dling foamy and del- 

 icate liquors. 



Construction. 

 The Buflovak Rapid 

 Circulation Evapora- 

 tor consists of a 

 horizontal cylindric- 

 al vapor body. To 

 this is bolted an in- 

 c 1 i n e d cylindrical 

 steam-chest. 



The vapor body 

 is equipped with a 

 baffle plate which ex- 

 tends across its cyl- Pi?> 73 . The Buflovak rapid circulation evaporator
