On October 10th, the autumn sun was shining. In the Fengyuan salt field managed by Shandong Wudi Haifeng (Group) Co., Ltd., a crystallization pond is producing salt. The crystallization pond is 80 meters long and 50 meters wide, and the seawater inside is pumped dry, revealing crystalline sea salt about 5 centimeters thick. A special small forklift is busy in the pond to transport the sea salt to the salt pump. The salt pump continuously pumps the salt into the pipe, causing it to flow to the tall salt pile not far away.
On the salt pile, the sea salt that was transported fell one after another, and from a distance, it looked like a heavy snow was falling. The salt heaps shimmered silver in the autumn sun. To the south of the salt mound is an endless, sparkling brine and regulating tank.
On October 10, the Fengyuan salt field was producing salt.
Shandong Wudi Haifeng (Group) Co., Ltd. has a total area of 1.618 million mu (one mu is equal to 100 square meters) and an annual design capacity of 1 million tons of raw salt.
Wang Shusen, the person in charge of Fengyuan Salt Farm, said that on the 10th, three sets of equipment were collecting sea salt. "We call the salt out of the crystallization pond 'picking salt', and in the past, salt collection was all manual, and it was very sinful to pull the salt out of the bottom of the crystallization pond and then pick it out." The 54-year-old said with a smile, "Now it only takes four or five hours to produce a pool of salt, all by machinery." ”
On October 10, the Fengyuan salt field was producing salt.
The reporter saw at the scene that there were 3 forklifts pushing salt in the crystallization pool where salt was being produced; The transport process from the pond to the salt pile is not supervised; There are two workers on the salt pile, who are responsible for adjusting the conveyor port so that the final salt pile forms a three-dimensional trapezoidal shape on the flat ground.
Fengyuan Salt Field is producing salt crystallization ponds.
Gao Hongbin, manager of the industrial salt department of Shandong Wudi Haifeng (Group) Co., Ltd., said that there are 186 crystallization ponds in the beach fields of Fengyuan Salt Farm. Seawater with a salinity of about 2% is pumped into the conditioning tank and flows into the brine tank when the salinity reaches a certain concentration. The seawater eventually enters the crystallization pond, where the salinity reaches 25% and the sea salt is crystallized. The total area of the regulating tank and the brine making tank is twice that of the crystallization tank.
Wang Shusen said that in winter, the temperature is low, the evaporation is low, and there is basically no salt production; In summer, there is a lot of rain, and there is basically no salt production; Salt production depends on spring and autumn. A crystallization pond can produce 300 tons of spring salt and 200 tons of autumn salt a year in a normal year. "We started picking salt on October 4 this year, and we were able to pick up the salt in 186 crystallization pools in about 20 days."
2% of the seawater, from the shore of the sea, under the action of the sun and wind, the salinity gradually increases, from one pond to the next, and finally produces a grain of sea salt. For the salt-drying people in the seaside beach fields, it is "hard work".
