Problems solved by technology

[0004] The composition of seaweed is complex, high temperature is easy to dissolve a large amount of colloidal substances, which makes subsequent extraction and filtration more difficult, and more steps such as decolorization, deodorization, degreasing, and purification are required to prepare a stable extract product. The intermediate steps often use organic reagents such as ethanol and methanol, and organic materials such as resins. The process is complicated, the cycle is long, the cost is high, it is not safe and not environmentally friendly. In addition, because the seaweed medicinal materials will seriously swell when they absorb water, it is not suitable to use foreign materials with relatively higher extraction efficiency.

Embodiment 1

[0045] Weigh seaweed medicinal materials into a rotating basket extraction tank, add the same amount of 200 mesh activated carbon, add 20% propylene glycol solution that is 5 times the amount of medicinal materials, and perform rotational extraction at 75°C for 2 hours, and the alternating time of forward and reverse rotation is 15 minutes ; Add 1.5% diatomaceous earth to the extract and settling time for 2 hours, take the supernatant and filter it with a 0.22 micron ceramic membrane until the permeate reaches 85% of the added amount. The total sugar content of the obtained extract is 0.74%, the mannitol content is 0.61%, the alginic acid content is 0.57%, the total polypeptide is 0.37%, and the accelerated test stability is 2.5 months.

Embodiment 2

[0047] Weigh seaweed medicinal materials into a rotating basket extraction tank, add the same amount of 100-mesh activated carbon, add 20% butanediol solution that is 10 times the mass of medicinal materials, and carry out rotation extraction at 50°C for 3 hours, and the alternating time of forward and reverse Add 2% diatomaceous earth to the extract and settle for 2 hours, take the supernatant and filter it with a 0.45 micron ceramic membrane until the permeate reaches 75% of the added amount. The total sugar content of the obtained extract is 0.70%, the mannitol content is 0.58%, the alginic acid content is 0.59%, the total polypeptide is 0.30%, and the accelerated test stability is 2.5 months.

Embodiment 3

[0049] Weigh seaweed medicinal materials into a rotating basket extraction tank, add the same amount of 100-mesh activated carbon, add 30% butanediol solution that is 8 times the amount of medicinal materials, and perform rotational extraction at 65°C for 1.5 hours, alternating forward and reverse The time is 20 minutes; the extraction solution is added with 1% diatomaceous earth for 2 hours, and the supernatant is microfiltered with a 0.45 micron ceramic membrane until the permeate reaches 80% of the added amount. The total sugar content of the obtained extract is 0.67%, the mannitol content is 0.54%, the alginic acid content is 0.51%, the total polypeptide is 0.31%, and the accelerated test stability is 3 months.

Abstract

The invention provides a method for preparing a seaweed extracting solution and a rotation basket extracting device. The preparing method includes the steps that seaweed and activated carbon are thrown into a plurality of medicine baskets, and meanwhile solvent is added into a tank body; a motor is started, a center shaft is made to rotate, hence, the medicine baskets are driven to make centrifugal movement, and chemical substances included in the seaweed are extracted through the solvent; after extracting is completed, the extracting solution is discharged from a liquid medicine outlet; the extracting solution is settled through kieselguhr; supernate is collected, microfiltration is conducted through a ceramic membrane, permeate liquid is collected, and accordingly the seaweed extracting solution is obtained. The rotation basket extracting device comprises the tank body, the center shaft and the medicine baskets. The center shaft penetrates in the center of the tank body in a rotating mode, the medicine baskets are arranged on the center shaft, solvent inlets and a medicine change opening are formed in the top of the tank body, and the liquid medicine outlet is formed in the center of the bottom of the tank body. The method has the advantages of being simple in process, short in period, environmentally friendly and safe. The content of active substances of the prepared extracting solution is high, the number of varieties of active ingredients is large, and stability is achieved.

Description

technical field [0001] The invention relates to a preparation method of seaweed extract and a rotating basket extraction device, belonging to the technical field of cosmetic raw material preparation. Background technique [0002] Seaweed is rich in polysaccharides, polypeptides, mannitol, amino acids, trace elements, polyphenols and other active ingredients. It is a plant active raw material commonly used in cosmetics. Radiation, hair growth and hair care and other effects, and it is safe and non-irritating. The preparation method of cosmetics prefers to use liquid raw materials. How to prepare seaweed extracts that are stable and retain active substances has practical guiding significance. [0003] The current seaweed research and development and patents are mainly focused on the preparation of seaweed polysaccharides and other solids, such as CN1318566, CN1377896, CN103739726A, etc. There are also liquid preparations, such as CN1122667, but this solution is mainly used for...
