Sea salt, as one of the oldest condiments of mankind, still plays an irreplaceable role in many industries around the world, such as food, chemical, pharmaceutical, leather, etc. With the continuous improvement of people’s requirements for the quality of salt, the production method of sea salt is also gradually transforming from the traditional mode of “sun drying + air drying” to automated, clean and efficient modern manufacturing. Especially in large salt fields and refined salt processing plants, higher requirements are put forward for production efficiency, product purity and resource utilization.
In this wave of salt production process upgrades, centrifuges are becoming an indispensable core equipment in the process of sea salt separation with their technical advantages such as efficient dehydration, precise separation and automatic control. It not only significantly improves the separation efficiency and quality of salt, but also reduces energy consumption and labor costs, helping salt companies achieve green, efficient and sustainable development.
Traditional methods and existing problems of sea salt separation
History and limitations of solar salt production
The coastal areas have adopted solar salt production since ancient times, using seawater evaporation to form salt fields, concentrating the brine to precipitate salt crystals, and then collecting, drying and packaging manually or mechanically. Although this process is energy-saving and environmentally friendly, it is inefficient, greatly affected by weather, and has large fluctuations in product quality.
The main problems include:
Long cycle: the natural evaporation and crystallization cycle can last for weeks to months;
High moisture content: the crude salt has a high moisture content and needs secondary drying or drying;
Many impurities: contains a large amount of impurities such as mud, quartz, and magnesium salts;
High labor intensity: relies on manual collection and transportation, and has low efficiency;
Difficult to ensure hygiene: affected by environmental pollution, bird feces, etc.
Faced with the market’s requirements for high purity, low impurities, and fast delivery, the traditional salt production process urgently needs to be upgraded to industrialization and high efficiency.
