摘要
Murotokaiyoshinnsousui Co. Ltd. located in the east of Kochi Prefecture produces salt and mineral liquid by the solar evaporation process with Muroto Deep Sea Water. This method has an advantage of making high quality salt and mineral to meet the demand of customers. But on the other hand, this has some problem for intentional production and mass production under the influence of the weather. Therefore, this study are aimed to develop a significant industrial production process of salt and mineral to get a equal quality of existing ones produced by the solar evaporation process with Deep Sea Water, which shall be realized to be able to make a intentional and mass production with more low cost. Particularly, this paper presents the multiple-effective Vacuum-evaporator which is one of the concentrators. We define this multiple-effective Vacuum-evaporator as a process device to extract gypsum from concentrated deep sea water, and make decision for density of concentrated water. And also, we have practical inspection for automatic concentration operation. The results are summarized as follows: (1) Acceptable production tolerance was controlled by less than 10% as a result of practical inspection for concentrated Deep Seawater waste at the boiling point of multiple-effective Vacuum-evaporator based on the target of Baume's value 10. (2) When we studied about concentrated control using by the conductivity meter, we got the result in error value by less than ±0.2 and in tolerance ratio by less than 2% against target of Baume's value 10. It means to be possible to produce salt and mineral using by Deep Seawater Waste to meet precisely with target concentration density.
