Continuously Dynamic Mixing (CDM) Method and Greenhouse Salt Tunnel (GST) Technology for Sea Salt Production throughout the Year

One of the biggest challenges in sea salt production is unpredictable and unsuitable weather. Sea salt production process is very depended on the evaporation rate of sea salt production and it will be stopped in the rainy season. One of the alternative strategies to solve this problem is the application of greenhouse salt crystallization in sea salt production. This study aims to develop the technology to produce sea salt in the rainy season by applying Continuously Dynamic Mixing Method (CDM) in the Greenhouse Sea Salt Tunnel (GST). The application of CDM in the GST is an original innovation developed by the researchers of this study. Environmental parameters analyzed in the present study were daily temperatures, wind speed, evaporation rate, humidity, and Baume scale value. The quality of the produced sea salt was evaluated from the water and NaCl content. The results of this study indicate that the application of the CDM method in GST makes the sea salt production from the raw water materials (± 2° Be) can be conducted in the rainy season. The optimum water and NaCl content of the produced sea salt is 98.05 % and 7 %, respectively. The production of sea salt for one cycle (15 days) in this study is 300 kg/GST-Crystallization (44 m²). According to the results, the CDM method in the GST technology may improve the production of the sea salt in the rainy season and allow it to produce sea salt throughout the year.
