In the Preuious report (Vol.9. No.1), the authors have reported the results of fndamental experiments, that is, the scale can be prevented by the method of "Addition of crystal seeds". That method was the use of suspended crystal seeds (calsium sulfate crystals) in the brine in the evaporaters. Crystal seeds act calsium sulfate depositing from the brine and make them grow on these crystal seeds rather than the tubes.<BR>This report, basing on the principle of 1st one, is written on application to present salt evaporating appratus, that of Odawara Salt Eperiment Station and Onahama Factory, Japan Monopoly Corporation. The authors have as we expected obtained same results on applying the fundamental experiments to evaporaters. Here, we can conclude that, the method of addition of crystal seeds is possible to concentrate the brine long time continuously, without scaling in auto-vapour compression system and vacuum system (No.1 evaporater).
