It is good to refine edible salt with Huai salt.

Huai salt is a kind of salt, named after the Huaihe River runs through Jiangsu saltworks. It has the reputation of "the benefit of cooking the sea, and the Huaihe River is the most important" and "East China Treasury". Known for its characteristics of "white color, large grain size and dryness", on September 1, 215, workers in Houzui Seaside Industrial Zone of Taibei Salt Field in Lianyungang City, Jiangsu Province were engaged in salt scraping. Since that day, 5, mu of raw salt in Lianyungang has fully entered the "autumn scraping" operation, and the workers seized the fine weather and stepped up the harvest of raw salt.

Huai salt is named after the Huaihe River runs through Jiangsu saltworks. Jiangsu saltworks are distributed in the oblique and long coastal zone from the Embroidered Needle Estuary at the junction of Sulu and Shandong in the north to the Yangtze Estuary in the south, spanning 13 counties and districts in Lianyungang, Yancheng, Huai 'an and Nantong, covering an area of 653 square kilometers. Jiangsu coast has the largest and widest coastal beach in China, and the climate conditions with four distinct seasons are suitable for sea salt production. Huai salt producing area is one of the four major sea salt producing areas in China.

the development of Huai salt

After the founding of the People's Republic of China, Huai salt has developed rapidly as an important industry related to the national economy and people's livelihood. Since the "First Five-Year Plan", the salt field has been constantly undergoing technological transformation towards the direction of rationalization of salt field structure, scientific technology, mechanization of production and concentration of tide absorption, brine production, crystallization and lump collection. The salt production has been greatly developed, and the backward appearance of the salt field has been quickly changed.

since 196, Jiangsu salt field has built a standardized and mechanized new salt field, which greatly improved the output and quality, and successfully tested the new technology of plastic film mulching crystallization pool, and then popularized it in a large area, achieving a historic breakthrough in the production technology of sea salt.

it has opened up a new road for the perennial production and long-term crystallization of sea salt in rainy areas, achieving high quality, high yield and stable yield of sea salt, and created conditions for gradually realizing the mechanization of pumping water, making brine, collecting salt and transportation. This technology was pioneered by Jiangsu salt industry, affirmed by international salt experts and won the national scientific and technological progress award.
