Abstract
A kind ofly handle red algae with potassium hydroxide solution and make and be used for food, the carrageenin of medicine, cosmetic industry, and do not have the method for environmental pollution.Used potassium hydroxide solution concentration is 5-30% (weight), and the temperature of processing is that room temperature to 80 ℃ contains Repone K waste liquid and algae-residue, according to the needs of Different Crop, and the compound manure of preparation heterogeneity.
Description
Technical field: the manufacture method of carrageenin
Patent CN 85 1 04000 A of reference: Zheng Shuzhen
The present invention is directed to three shortcomings of patent (the CN 85 1 04000A) method of Zheng Shuzhen, improve.
The shortcoming that when (1) with saline solution (containing sodium hydroxide) some husky algae being heat-treated, still has " mashed dish " can be avoided " mashed dish ", the easier implementation of technology yet the present invention uses potassium hydroxide solution instead.
(2) saline solution primary treatment method, the color of product is pure white inadequately, and (n=1,2,3) facture that the present invention uses potassium hydroxide solution instead n time has reduced pigment effectively, is beneficial to and obtains pure white product.Simultaneously, gel-strength also significantly improves.
(3) existing carrageenin factory all produces a large amount of waste residues every day and contains waste liquid, the especially latter of sodium hydroxide and sodium-chlor, emits, and causes pollution and destruction to environment can not be ignored.The present invention uses potassium hydroxide instead and replaces after the sodium hydroxide, contain in the potassium hydroxide waste liquid and after, become the waste liquid that contains Repone K, no longer discharging.It is mixed with algae-residue, the system of macerating, dry.These contain and enrich fertile and organic " refuse " of K, by analysis, need by Different Crop, replenish an amount of N or P fertilizer, the compound manure of preparation different components.
The present invention is a kind of high quality producing kara rubber that does not have environmental pollution.
Example: 1
The Mi Maosha dish of 10 weight parts (Hypnea boergesenij) washing, with 30 times of amount 10% potassium hydroxide solutions, handled 8 hours in 75 ± 5 ℃, venting (for the first time) alkali lye, again with amount potassium hydroxide solution re-treatment together, (alkali lye can give over to batch of material do alkaline purification for the first time liquid next time for the second time), washing, bleach with the chlorine bleach liquor, use the hypo solution dechlorination, be washed to neutrality, boil glue with 30-35 times of clear water, filtration, gelling, push away bar, freezing, dewater, dry, strip carrageenin product.
Example: 2
10 weight parts collude husky dish (Hypnea cervicornis) washing, to boiling glue, filtration, gelling, product then squeeze, dewater, dry, pulverize, must the powdery OK a karaoke club be temporarily released from one's regular work with the method for example 1.
Claims (6)
1, a kind of potassium hydride KH solution-treated of using--red algae is made the method for carrageenin, it is characterized by that potassium hydroxide solution is dense to be crossed into 5-30% (weight); According to different requirements, take N (N=1.2.3) alkaline purification to the pure white degree of product.
2, by claim 1 described method, the alkaline purification second time liquid of preceding a collection of raw material can give over to the next batch raw material and make the liquid of alkaline purification for the first time.
3, by claim 1 described method, its feature its alkali purification temp is a room temperature to 80 ℃.
4, by claim 1 described method, its feature alkaline purification time is 8 hours * N time.（N＝1，2，3）。
5, by the described method of claim 1-4, the raw material of its processing is husky dish (Hypnea) or Qi phosphorus dish (Eucheuma).
6, by the described method of claim 1-5 its contain enrich the fertile and organic waste liquid of K mixes " waste material " with algae-residue can be by the Different Crop needs, additional an amount of N or P fertilizer is prepared the compound manure of heterogeneity.Here N fertilizer refers to urea or ammonium sulfate, ammonium nitrate, ammonium chloride; P fertilizer refers to calcium superphosphate.Fused(calcium magnesium)phosphate, ground phosphate rock etc.
