Embodiment 1

[0053] A method for industrialized production of sodium alginate by adopting South Africa's great kelp, comprising the following steps:

[0054] (1) Raw material treatment: Soak and wash South Africa’s largest kelp for three times; wherein the three soaks and washes use formaldehyde, formaldehyde and liquid caustic respectively in sequence; a. The first soak and wash: use formaldehyde to treat; After the big kombu is evenly put into the first-level pool, then add 1.6m 3 Tap water and 30Kg formaldehyde solution, wherein the mass fraction of formaldehyde solution is 36.5%; finally turn on the Roots blower for 10 minutes, mix well and soak for 24 hours; control the concentration of formaldehyde solution in the pool during the soaking process between 0.6% and 0.8%;

[0055] b. The second soaking and washing: use formaldehyde treatment; after 24 hours of soaking and washing for the first time, first use

[0056] After the pump is washed by the first-level washing cage, it is sent ...

Embodiment 2

[0067] A method for industrialized production of sodium alginate by adopting South Africa's great kelp, comprising the following steps:

[0068] (1) Raw material treatment: Soak and wash South Africa’s largest kelp for three times; the three soaks and washes use formaldehyde, formaldehyde and liquid caustic respectively in turn; a. The first soak and wash: use formaldehyde to treat; After the big kombu is evenly put into the first-level pool, then add 2.4m 3 Tap water and 45Kg formaldehyde solution, wherein the mass fraction of formaldehyde solution is 36.5%; finally turn on the Roots blower for 10 minutes, mix well and soak for 24 hours; control the concentration of formaldehyde solution in the pool during the soaking process between 0.6% and 0.8%;

[0069] b. The second soaking and washing: use formaldehyde treatment; after 24 hours of soaking and washing for the first time, first use

[0070] After the pump is washed by the first-level washing cage, it is sent to the secon...

Abstract

The invention belongs to the technical field of seaweed chemical industry and in particular relates to a method for industrial production of sodium alginate by adopting South Africa great kelps. The method for industrial production of sodium alginate by adopting South Africa great kelps comprises the following steps: (1) raw material treatment; (2) digestive extraction; (3) separation impurity removal; (4) calcification calcium removal; (5) secondary dehydration; (6) quantitative neutralization; and (7) drying, grinding and packaging. By adopting the method provided by the invention, certain key problems in industrial extraction of sodium alginate by adopting South Africa great kelps as a main raw material are solved, the range of the raw materials for industrial production of sodium alginate is enlarged, and compared with a method using original algae including kelps, giant kelps, ascophyllum nodosum, gulfweeds and the like, the method for producing sodium alginate by using South Africa great kelps as the raw material has obvious economic benefits.

Description

technical field [0001] The invention belongs to the technical field of seaweed chemical industry, and in particular relates to a method for industrially producing sodium alginate by adopting South African giant kelp. Background technique [0002] For a long time, the production of sodium alginate in China has used artificially cultured kelp as the main raw material. In recent years, due to the rapid development of kelp in the food and sea cucumber bait market, the price of kelp has skyrocketed, from 4000-4500 yuan / ton a few years ago to 5500-6000 yuan / ton, so domestic sodium alginate production plants Started to develop new raw material markets, and purchased macroalgae from South America in large quantities, resulting in a soaring price of macroalgae in South America. The price of macroalgae has soared from US$700 / ton in 2011 to US$1,600 / ton now. [0003] Because kelp, Ascophyllum nodosum, and giant algae are mostly Prototheca with loose algal tissue, less fiber, lighter a...
