Embodiment Construction

[0026] The present invention is further stated below:

[0027] The new method of the invention comprises raw material kelp pretreatment, kelp digestion treatment, and sodium alginate finished product preparation; after raw material kelp pretreatment and before kelp digestion treatment, there is kelp pretreatment. The raw material kelp can be pretreated by putting fresh kelp into formaldehyde soaking solution to soak and store for later use. Or the pool storage space can be set according to the annual demand of the enterprise, and the raw material kelp pretreatment can also adopt the pretreatment method in the prior art of light dry kelp. The formaldehyde solution mainly plays the role of color fixation and anticorrosion. The content of formaldehyde (by weight %) value is not limited to the above-mentioned range, it can play a color-fixing and anti-corrosion effect; the sea-tangle pre-treatment is realized in this way, and the sea-tangle obtained in the above-mentioned pretreat...

Abstract

The sodium alginate producing process includes raw material kelp pre-treatment, kelp digestion and sodium alginate product preparation and features the front-stage treatment between the pre-treatmentand digestion, in which kelp is soaked in NaClO solution to turn in color from brown into light green or white, water flushed, HCl solution soaked to eliminate pigment, sugar gum, Ca ion, etc. The process is short, simple and high in production efficiency.

Description

(1) Technical field [0001] The present invention relates to sodium alginate product in marine chemical industry, especially related to its production method. (2) Background technology [0002] The method for producing sodium alginate in the current technology has the following steps: lightly dry kelp → soak and wash → digest → dilute → foam and float → filter → calcify → decalcify → dehydrate → neutralize → granulate and dry → grind the finished product. The above-mentioned links are briefly explained. [0003] (1) Light-dried kelp: The mature kelp produced in the sea is naturally dried and stored as light-dried kelp for later use. [0004] (2) Soaking and washing: Put the lightly dried kelp into the soaking pool, add fresh water to soak and wash, the soaking liquid is used to produce iodine and mannitol, the amount of water added is about 15 times that of the dried kelp, and formaldehyde is added to fix the color when soaking. [0005] (3) Digestion: Cut the washed kelp i...
