Abstract
A kind ofly handle fragrant plant mentioned in ancient texts, make the high quality agar-agar, and do not have the method for environmental pollution with potassium hydroxide solution.Concentration of used potassium hydroxide solution is that 5-30% (weight) its alkali purification temp is a room temperature to 90 ℃; The waste liquid and the algae-residue that contain Repone K are according to the compound manure of the needs of Different Crop preparation heterogeneity.
Description
Art field: the manufacture method of agar-agar
Reference: the research (I) of people's gracilaria verrucosa agar gels such as (1), the bright time of recording
" aquatic product journal " 1965.6
(2), the research (II) of people's gracilaria verrucosa agar gel such as Shi Shengyao
" aquatic product journal " 1982.3
Existing gracilaria verrucosa agar gel production method all adopts sodium hydroxide solution to carry out alkaline purification.There are two problems at present domestic manufacturer:
(1), the whiteness of product is not good enough, gel-strength is lower.
(2), produce a large amount of waste residues and waste liquid every day, the discharging of waste liquid that especially contains sodium hydroxide and sodium-chlor goes out cloud, causes the pollution to environment can not be ignored.
Content of the present invention and advantage thereof are:
(1), change the technology of existing sodium hydroxide solution primary treatment, replace with potassium hydroxide n time (n=1,2,3) and handle, make pigment as far as possible after the minimizing, bleach, boil operations such as glue again.Its advantage is to make product more pure white, and simultaneously, gel-strength also increases.
(2) even after containing the waste liquid neutralization of sodium hydroxide in the current methods, become the waste liquid of sodium chloride-containing, emit, still can cause the pollution of " salinization " to destroy the soil.After the present invention used potassium hydroxide instead, it became " waste liquid " that contain Repone K through neutralization, no longer discharging.It is mixed with algae-residue, the system of macerating, dry, these contain to have and enrich K fertile and organic " refuse ", by analysis, by the needs of Different Crop, replenish an amount of N and P fertilizer, the compound manure of preparation different components.
The present invention is a kind of do not have environmental pollution, high-quality agar-agar manufacture method.
Example: the Gracilaria tenuistipitata of 10 weight parts (Gracilaria tenuisfiptata), washing, potassium hydroxide solution with 30 times of amounts 10%, handled 8 hours in 85 ± 5 ℃, venting (for the first time) alkali lye, again with amount potassium hydroxide solution re-treatment together, (alkali lye can give over to next batch of material and make treatment solution for the first time for the second time), washing is bleached with the chlorine bleach liquor, use the hypo solution dechlorination, be washed to neutrality, doubly measure clear water with 20-25 and boil glue, filtration, gelling, push away bar, freezing, the dehydration, dry, get strip agar-agar product.
Claims (6)
1, a kind of potassium hydroxide solution is handled fragrant plant mentioned in ancient texts, makes the method for agar-agar, and it is characterized by the potassium hydroxide solution weight percent concentration is 5-30%; According to different requirements, adopt n (n=1,2,3) alkali lye to handle 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 90 ℃.
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 fragrant plant mentioned in ancient texts (Gracilaria).
6, by the described method of claim 1-5, it contains and enriches fertile and organic waste liquid and the algae-residue blended " waste material " of K, can need by Different Crop, replenishes an amount of N or P fertilizer, prepares the compound manure of different components.Here N fertilizer refers to urea, ammonium sulfate, ammonium nitrate, ammonium chloride; P fertilizer refers to calcium superphosphate, fused(calcium magnesium)phosphate, ground phosphate rock etc.
