Problems solved by technology

The disadvantages of this method are: it directly uses kelp as raw material, important products such as mannitol and iodine in kelp are not utilized, and the process is complicated. It is not feasible to enzymatically decompose kelp with compound enzymes in large-scale production
Because the source of enzymes is generally very expensive, and the market price of the kelp dietary fiber produced cannot be too high, the production cost great

Embodiment 1

[0029] Embodiment 1: 1000m of alginate plant discharge 3Add 10% calcium chloride solution to the turbid glue pool of seaweed residue until the seaweed residue is flocculated, and collect the seaweed residue flocs with a centrifuge. Take 20 kg of collected wet kelp slag flocs and put them into a stirring reaction tank, add 100-120 kg of water and 1500 g of hydrochloric acid, heat to 30-60°C, stir for 2-3 hours to decalcify, centrifuge with a centrifuge, and collect the kelp Slag is solid; repeat again (add 100-120 kg of water and 1500 g of hydrochloric acid, heat to 30-60°C, stir for 2-3 hours to decalcify), rinse with water until the pH value of the kelp slag glue is neutral, and then centrifuge to obtain kelp Slag solid. Put the solid into the stirred reaction tank again, add 100-120 kg of water and 100-120 g of sodium carbonate, heat it to 45-55 ° C in the stirred reaction tank, keep it warm for 2-3 hours to become black liquor, and then wash the black liquor with water. s...

Embodiment 2

[0030] Embodiment 2: Get 20 kg of wet kelp slag collected by flocculation according to Embodiment 1 and put it into a stirring reaction tank, add 120-140 kg of water and 270-660 g of concentrated hydrochloric acid, heat to 40-65 ° C, and stir for 3-4 hours, centrifuge and collect the kelp slag solid; repeat again (add 120-140 kg of water and 270-660 g of concentrated hydrochloric acid, heat to 40-65 ° C, stir for 3-4 hours to decalcify), and wash with water until neutral, leave Experience kelp slag solid. Put the solid into the stirred reaction tank again, add 110-130 kg of water and 90-110 g of sodium carbonate, heat it to 40-50 ° C in the stirred reaction tank, keep it warm for 3-3.5 hours, and then wash off the black liquor with water to pH The value is neutral, and the filter cake is taken by centrifugal dehydration; then add 120-160 kg of water, 50-85 g of stabilizer sodium phosphate, and 1 kg of bleaching agent H to the filter cake 2 o 2 , bleach at 85-95°C for 2.5-3.5...

Embodiment 3

[0031] Example 3, put 20 kg of wet kelp slag collected by flocculation according to Example 1 into a stirring reaction tank, add 100-120 kg of water and 300-600 g of concentrated hydrochloric acid, heat to 50-70°C, and stir for decalcification for 3-6 hours, centrifuge to collect the kelp slag solid; repeat (add 100-120 kg of water and 300-600 g of concentrated hydrochloric acid, heat to 50-70°C, stir for 3-6 hours to decalcify) twice, and wash with water until neutral, Centrifuge to get kelp slag solid. Put the kelp slag solid into the stirring reaction tank again, add 120-140 kg of water and 50-70 g of sodium carbonate, heat it to 55-75 °C in the stirring reaction tank, keep it warm for 3-5 hours, and then wash off the black liquor with water until the pH value is neutral, centrifugal dehydration, then add 130-160 kg of water and 70-130 g of stabilizer sodium sulfate, and (1 kg of bleach) H 2 o 2 , bleach at 90-100°C for 4-7 hours. After a bleaching, continue to carry out...

Abstract

The kelp diet fiber product is white powder extracted from kelp dreg and has fiber content of 50-94 %, water maintaining capacity of 700-2100 %, swelling capacity of 10-30 ml/g, high purity and activity. The production process includes collecting flocculate, adding acid to eliminate calcium, alkali treatment, bleaching, washing, and drying and crushing into 160-200 mesh. The production process is simple, full in utilizing kelp and low in cost, and has less waste water drainage, non-toxic bleaching agent with sterilizing function used. The product is good for health.

Description

(1) Technical field [0001] The invention relates to the improvement of a comprehensive utilization project of seaweed chemical industry, in particular to the seaweed dietary fiber produced by using the seaweed waste residue after rubber extraction and the production method thereof. (2) Background technology [0002] In the early 1980s, there were reports on the physiological functions of dietary fiber in my country, but no in-depth research and large-scale production have been carried out. It has been reported successively: the research of extracting dietary fiber by using wheat bran, soybean, sugar beet, shiitake mushroom, bagasse and persimmon skin, etc., and obtained large-scale production in a local range. At present, most of the research on dietary fiber in our country stays in terrestrial plants, and in the marine field, especially the research and development of high-activity dietary fiber on seaweed and kelp resources is still a pioneering research work in our countr...
