Production process of sodium alginate
Description of process flow:
After the kelp is weighed, it is soaked in water 5 times the weight of dry kelp for 20 hours, drained, soaked in tap water and liquid alkali for 3 hours, and the wet kelp soaked for five times is sent to a pulverizer to be crushed to 2-3mm, washed with water, dewatered in a cage and sent to a digester; Adding 1% hot alkaline water (sodium carbonate) at 80℃ to kelp in a digester, stirring uniformly, standing for two hours, performing primary pulping, digesting for one hour, performing secondary pulping, and digesting for 0.5 hour, performing tertiary pulping, then placing in a dilution pool, diluting until it reaches Engel's for 100-120 seconds, uniformly mixing with compressed air, sending to a foaming machine for foaming and settling for 2.5-3 hours. The filtrate is pumped into a calcification system for calcification, and chlorine gas is added for bleaching at the same time, and 1% calcium solution (calcium chloride concentration is 10%) with glue solution is added, which is foamed by a foaming device and stirred at high speed, then enters an aging tank, and then enters a decalcification bucket to be decalcified with 5% hydrochloric acid, and then enters a cage for dehydration. After three decalcification, it is squeezed and dehydrated to generate alginic acid, which is then sent to a liquid phase converter and added with 75% ethanol solution. Neutralization to pH 9, centrifugal dehydration (distillation and recovery of waste ethanol solution), granulation and granulation of centrifugal sodium alginate, drying in a dryer until the water content is 16%-17%, and then grinding in a mill to 40.Eye, after inspection, packaging factory.

The cost of seaweed production in fertilizer, labor and machinery is also lower than that of terrestrial energy crops. At present, energy crisis is frequent, environmental problems are prominent, land reserve is sharply reduced, and crop production is weak. It is of great significance to increase the utilization of marine living resources, especially the comprehensive utilization of seaweed. Let's introduce the benefits of seaweed as a pet grooming formula.
First, beautiful hair, increase pigment deposition
Natural seaweed powder can promote the metabolism of skin cells, delay cell aging, enhance skin elasticity, prevent hair from drying off, promote the growth of new hair, help hair restore its natural color, help pigment precipitate, and effectively keep the nose black.
Second, protect skin health
Natural seaweed powder can reduce the incidence of skin diseases, improve skin allergy and itching, accelerate the healing of skin diseases and promote the recovery of wounds.
Third, enhance physical fitness
Protein, amino acids, carbohydrates, vitamins and minerals in natural seaweed powder can improve the immune system, strengthen bones, strengthen physical fitness and endurance, and resist diseases.
