Abstract
The invention relates to a method for recycling hemp strain-containing degumming liquid for degumming hemp, relating to a hemp degumming process method and mainly solving the problems of the traditional hemp degumming method, such as long degumming period, low fiber yield, low hemp fiber strength and large sewage discharge during retting. The method disclosed by the invention comprises the following steps of: activating strains used for degumming hemp; carrying out primary seed culturing; carrying out second-degree seed culturing; carrying out third-degree seed culturing; degumming hemp with strains; recycling hemp strain-containing degumming liquid and adding to a new hemp degumming pond, and then adding hemp stalks, sodium chloride and urea, filling clean water into the hemp degumming pond, increasing the temperature for retting and completing the degumming process when a retting terminal point is reached. By adopting the method disclosed by the invention, 50% of waste water discharge can be reduced every day, energy consumed for degumming hemp is saved by 10%-15%; meanwhile, the degumming period of the hemp stalks is shortened to 80-120h, the hemp fiber yield is improved by 3%-5%, the hemp fiber strength is enhanced to 220-280N, and the quality of hemp fiber is improved.
Description
Technical field
The present invention relates to the method for hemp degumming.
Background technology
China adopts hemp degumming method to be at present: the wisp that at first big anesthesia stem is bundled into 20 centimeters diameters, to tie good big anesthesia stem then packs into and comes unstuck that loading density is 75～80 kilograms/cubic metre in the pond, the pond of will coming unstuck is then filled with, fill with the back and heat to needed temperature for the retted fibre pond with steam, mend temperature once to desired temperature with steam every day in the hemp degumming process.What adopt during terminal point in the judgement system of macerating is organoleptic method, and organoleptic method mainly just is meant " method of putting forth ": the straw of finishing in the position system of will macerating of the root 1/3rd of straw fractures, and xylem that can be wherein be arrival and macerate the system terminal point by extracting out in the fiber portion.
The fermentation period time that hemp warm water comes unstuck is long: have nothing in common with each other kind and the harvest time for the big anesthesia stem of hemp raw material plant at present, cause the composition of fiber in the diameter of big anesthesia stem and the bast to have nothing in common with each other, this is mainly reflected in the different of temperature and usually time of coming unstuck, and the degumming tech operative norm of each raw material plant neither be very consistent.The temperature of coming unstuck of general big anesthesia stem is 30 ℃～33 ℃, and macerating the system time is 120～168h.
The fibre percentage that hemp warm water comes unstuck is lower with respect to technology of the present invention: adopt the present invention can make the hemp fibre percentage improve 1.5%～2%, wherein fibre percentage is meant the weight shared former scapus heavy ratio of the hemp scapus of constant weight through the resulting hemp of system fiber crops processing.
The hemp warm water hemp intensity of producing of coming unstuck is low: adopting natural Degumming method fibre strength that big anesthesia stem produces is 170～180N.
The hemp warm water energy consumption of coming unstuck is bigger: hemp degumming production need make the temperature in the retted fibre pond reach certain temperature, realize that this condition factory need adopt steam to mend temperature, like this every day each pond to mend the temperature once need to expend a large amount of steam, promptly to expend a large amount of fire coals.Add the method that the bacterium degumming baths carries out hemp degumming and have the big problem of quantity of wastewater effluent of macerating in the system and adopt.
Summary of the invention
The present invention be for the method that solves existing hemp degumming exist the cycle of coming unstuck long, fibre percentage is low, hemp intensity is low, macerate the big problem of quantity of wastewater effluent in the system, and provides hemp to add the method for bacterium degumming baths recycling carrying out hemp degumming.
Hemp adds bacterium degumming baths recycling and carries out the method for hemp degumming and realize according to the following steps: one, hemp degumming is with the activation of bacterial classification: colon bacillus HDDMG05 and bacillus licheniformis HDDMM02 are cultivated 24h respectively on beef-protein medium under 30 ℃; Two, first order seed is cultivated: with oese respectively the bacterial classification of picking step 1 activation access in 200～500mL industry enlarged culture base, under 28～32 ℃ of conditions, cultivate 20～30h; Three, secondary seed is cultivated: the bacterium liquid after first order seed is cultivated by volume mark is that 0.5%～2% inoculum concentration is linked in 200～500L industry enlarged culture base, cultivates 20～30h under 28～32 ℃ of conditions; Four, three grades of seed culture: the bacterium liquid after secondary seed cultivated by volume mark is that 0.5%～2% inoculum concentration is linked in 2～5t industry enlarged culture base, cultivates 20～30h under 28～32 ℃ of conditions; Five, in the hemp degumming pond, add the big anesthesia stem of 4～6t, 2～2.5 kilograms sodium chloride and 3～5 kilograms urea, then the bacterium liquid after three grades of seed culture is linked in the hemp degumming pond with 1% of big anesthesia stem weight, fill with the hemp degumming pond with clear water again, heat to 30 ℃～33 ℃ and macerate the system hemp, adopt the method for putting forth to judge to arrive to finish when macerating the system terminal point to adopt to add the bacterium degumming baths and carry out hemp degumming; Adding of producing when six, the system terminal point is macerated in arrival in the step 5 joins in the new hemp degumming pond after the bacterium degumming baths reclaims, add the big anesthesia stem of 4～6t, 2～2.5 kilograms sodium chloride and 3～5 kilograms urea again, fill with the hemp degumming pond with clear water again, heat to 30 ℃～33 ℃ and macerate the system hemp, adopt the method for putting forth to judge to arrive and finish hemp when macerating the system terminal point and add bacterium degumming baths recycling carrying out hemp degumming;
Wherein the HDDMG05 of colon bacillus described in the step 1 is preserved in Chinese typical culture collection center, deposit number is CCTCC No:M 208082, preservation date is on June 2nd, 2008, and patent name is " a kind of engineered strain that produces pectase ", and publication number is CN 101386825A;
The HDDMM02 of bacillus licheniformis described in the step 1 is preserved in Chinese typical culture collection center, deposit number is CCTCC No:M 208081, preservation date is on June 2nd, 2008, and patent name is " a kind of engineered strain that produces mannase ", and publication number is CN 101386824A;
Industrial enlarged culture base is the glucose by 10g in the step 2, the soybean diffusion juice of 10mL, and the macrogranule salt of 5g, the urea of 2g add water and are settled to 1000mL, and pH 7.0～7.2, and 30min sterilizes under 112 ℃ of conditions;
Add the addition that joins in the hemp degumming pond after the bacterium degumming baths reclaims in the step 6 and account for 50% of hemp degumming pool volume.
The present invention carries out hemp degumming and arrives the bacterium degumming baths that adds that produces when macerating the system terminal point and carry out recycling adding the bacterium degumming baths, all reduce by 50% discharge of wastewater (adding the discharge of wastewater that the bacterium degumming baths carries out hemp degumming with employing relatively) every day, save hemp degumming energy consumption 10%～15%; Simultaneously the cycle of coming unstuck of big anesthesia stem shortens to that 80～120h, hemp fibre percentage have improved 3%～5%, hemp intensity is brought up to 220～280N, has improved the hemp quality.
