Problems solved by technology

Although the ethanol precipitation method has the advantages of being easy to produce on a large scale, its main principle is to separate polysaccharides by reducing the dielectric constant of the aqueous solution to dehydrate the polysaccharides to produce precipitation. Step-by-step precipitation under the condition of ethanol, but the specificity is not high, resulting in poor separation selectivity for the required polysaccharides. To improve the purity of polysaccharides, repeated precipitation is required many times, resulting in a large loss of polysaccharides and reducing the recovery of polysaccharides Rate
[0005] In addition, the extraction methods of seaweed polysaccharides include flocculation extraction, circulating air-lift ultrasonic crushing extraction and solvent extraction extraction. These methods are mainly the extraction methods of pharmaceutical grade seaweed polysaccharides, which are costly and do not consider the comprehensive utilization of seaweed. , not suitable for agricultural production
[0006] Although more and more research results have shown that seaweed polysaccharides have broad development and application prospects, the existing seaweed polysaccharide leaching and separation technologies are costly, which restricts the large-scale production and wide application of seaweed polysaccharides.
In addition, in the existing seaweed extraction process, the separation and extraction of fucoidan is ignored

Embodiment 1

[0048] Agricultural product of the present invention adopts following steps to prepare:

[0049] 1). Cut clean fresh brown algae into 20-40cm 2 The left and right blocks were pulverized at a low temperature of -120~-140°C with a liquid nitrogen freezing ultrafine pulverizer (DFZ-2 Jiangyin Jinke Crushing Machinery Co., Ltd.).

[0050] 2). Put 10kg of the above-mentioned seaweed powder into the submerged ultrasonic extractor (TY-type KS and KS-C Ningbo Haishu Kesheng Ultrasonic Equipment Co., Ltd.), add 40kg of hot water at 60°C, stir with a stirrer, and use a frequency of Ultrasonic vibration at a frequency of 100KHz, the vibration breaks the seaweed cells for 30 minutes, filtering to obtain a filtrate, and the filter residue for later use.

[0051] 3). Take 100kg of the above filtrate, add 20kg of 10% AlCl 3 Mix the solutions, then slowly add 20kg of 10% KOH solution to form a precipitate, filter to obtain a filtrate and a precipitate, and the obtained precipitate is a mixt...

Embodiment 2

[0059] Agricultural product of the present invention adopts following method to prepare:

[0060] 1). Cut clean dry brown algae into 20-40cm 2 The left and right blocks were pulverized at a low temperature of -120~-140°C with a liquid nitrogen freezing ultrafine pulverizer (DFZ-2 Jiangyin Jinke Crushing Machinery Co., Ltd.).

[0061] 2). Put 10kg of the above-mentioned seaweed powder into the submerged ultrasonic extractor (TY type KS and KS-C Ningbo Haishu Kesheng Ultrasonic Equipment Co., Ltd.), add 100 kg of 80°C hot water, stir with a stirrer, and use a frequency of Ultrasonic vibration at a frequency of 50KHz, the vibration breaks the seaweed cells for 50 minutes, and filtering to obtain a filtrate, and the filter residue is used for later use.

[0062] 3). Take 100kg of the above filtrate, add 50kg of 10% AlCl 3 Mix the solutions, then slowly add 30kg of 10% KOH solution to generate a precipitate, filter to obtain a filtrate and a precipitate, the resulting precipitate...

Abstract

The invention discloses a comprehensive utilization usage of seaweed; especially production method of involving producing seaweed agricultural product and fucosido- polysaccharide; which comprise the following parts: adopting marine biology sodium as main material; applying freezing disintegrating technology, ultrasonic wave water and lixivium extraction steps; extracting inherent autogenous plant growing modifier in maximum limit and keeping biological activity; separating fucosido-polysaccharide and producing bottom of last leaving to fertilizer, soil modifier and fodder; that can be using fully.

Description

technical field [0001] The invention relates to a comprehensive utilization method of seaweed, in particular to a method for producing agricultural products such as seaweed fertilizer and soil conditioner by utilizing seaweed, and belongs to the field of fertilizers. The present invention also relates to a production method of fucoidan. Background technique [0002] Seaweed is a low-level photosynthetic nutrient plant that grows in the ocean and is the original producer of marine organic matter. Because seaweed grows in seawater, a special environmental medium, it not only contains the nutrients of land plants, but also contains trace elements such as iodine, potassium, magnesium, manganese, titanium, etc. Polysaccharides, Mannitol, etc. The special ingredient in seaweed - seaweed polysaccharide can not only chelate heavy metal ions, but also increase the air permeability of the soil. This soil air conditioning effect makes the soil not easy to be eroded and lost by wind a...
