Description
Technical field
The present invention relates to pueraria lobata processing technique field more particularly to a kind of methods of the quick slurry separation of pueraria starch.
Background technique
Pueraria starch is contained among pueraria lobata, and pueraria lobata is the subterranean organ of Pueraria lobota, general cylindric, plump, crust lark,
Internal silty, multifilament, perennial pueraria lobata will have a nutrient accumulation peak period, the content of starch in pueraria lobata every year
The corresponding change with the variation of season and developmental stage.In existing pueraria starch processing technology, pueraria starch is in process
Middle the impurity such as some Pueraria lobota slag staple fibers, skin, silt and starch mix and are difficult first separation after pulverizer crushes, and
By separation is filtered for multiple times, and separation purity is not high, and both wasting manpower and material resources, also increased time cost, and isolate
Pueraria starch yield it is lower, be unsuitable for the processing of large batch of pueraria starch, use chemistry in some pueraria starch processing technologys
Additive improves the slurry separation rate of pueraria starch, forms sediment although the finished product pueraria lobata that slurry separation rate is prepared can be improved
Chemical addition agent residual is more in powder, will affect the activity of the nutritional ingredient in pueraria starch, is crushed nutritive issue, long-term consumption
Pueraria starch containing additive is harmful to the human body.Therefore, a kind of method that the present invention proposes quick slurry separation of pueraria starch
To solve the shortcomings of the prior art.
Summary of the invention
In view of the above-mentioned problems, the present invention proposes that the secondary liquid of pipe prepared by pure plant Guan Zhong does not have any pollution,
Managing secondary liquid can be with the silt in rapid subsidence pueraria lobata slurry, and product is healthy and safe, does not contain chemical addition agent, is eaten for a long time to body
Be free from side effects, the method for preparing the secondary liquid of natural plants additive pipe is simple, easy to operate, easy to use, saves labor, save at
This.
A kind of method of the quick slurry separation of pueraria starch, comprising the following steps:
Step 1: sorting
Choosing nature, to grow not damaged disease-free fresh tube secondary spare, selects appearance as white or light brown, matter is hard and weighs, cuts
The coarse and pueraria lobata without the lesion that addles in face is spare；
Step 2: cleaning
It is impregnated with clear water by fresh tube is secondary, is cleaned up after immersion with clear water, pueraria lobata is put into immersion treatment in soak, impregnated
It is cleaned afterwards with flowing clear water；
Step 3: it crushes
Secondary be put into pulverizer of fresh tube after cleaning is crushed, obtains the secondary paste of pipe, taking-up is spare, then the pueraria lobata after cleaning is put
Enter in pulverizer and crushed, obtain pueraria root residue, takes out spare；
Step 4: secondary liquid is managed in preparation
The secondary paste of pipe is put into the first container, clear water is added into the first container and impregnates, the secondary precipitating of pipe is obtained and starches, then by Guan Zhongchen
The residue filter processing formed sediment in slurry, it is spare to obtain the secondary liquid of pipe；
Step 5: it prepares pueraria lobata and slightly starches
Pueraria root residue is put into second container, clear water is added, is stirred, obtains pueraria root residue mixed liquor, then pueraria root residue is mixed
It closes liquid to be filtered with bolter to slurry separation, obtains pueraria lobata and slightly starch, then pueraria lobata is slightly starched precipitating 24 hours, it is clear then to remove upper layer
Liquid obtains pueraria lobata and slightly starches；
Step 6: desanding
Pueraria lobata is slightly starched to be added in hydrocyclone and is carried out desanding 30 minutes, pueraria lobata is slightly starched again after desanding, disc separator is added
Separating treatment is carried out, pueraria lobata slurry is obtained；
Step 7: slurry separation
The secondary liquid of pipe and pueraria lobata slurry are put into stirred tank according to the ratio of 1:2, be mixed 30-40 minutes, is mixed
Liquid, then mixed liquor is stood 30 minutes, then the pure white liquid level on mixed liquor upper layer in stirred tank is extracted out with water pump and is collected, i.e.,
The pure slurries of pueraria starch can be obtained.
Further improvement lies in that: clear water soaking time is 30-40 minutes in the step 2, and the soak is deionization
Water and natural sea salt, manufactured soak after being mixed according to 5:1, the soak immersion treatment time are 20-30 minutes.
Further improvement lies in that: it is -5 degrees Celsius that built-in temperature is crushed in the step 3, the secondary crushing of fresh tube
Grade was 80-100 mesh, and the kudzu-vine root powder particle grade was 100-120 mesh.
Further improvement lies in that: secondary paste is managed in the step 4 and clear water ratio is 1:20, when impregnating in the step 4
Between be 24-30 hours.
Further improvement lies in that: filtration treatment is double-filtration processing in the step 4, and by-pass filtration was 140 meshes
Filtering, secondary filtration were centrifuge separation, will manage in secondary precipitating slurry addition centrifugal separator and carry out centrifugal treating, centrifugal separator
Revolving speed is 1000-1200 revs/min, and the centrifuge separation time is 5-8 minutes.
Further improvement lies in that: pueraria root residue and clear water ratio are 1:10 in the step 5, when stirring in the step 5
Between be 15-25 minute, speed of agitator be 200-300 revs/min, the bolter grade was 180 meshes.
Further improvement lies in that: separating treatment is that three-level separates concentration in the step 6, first slightly starches pueraria lobata and adds
Enter disc separator and carry out level-one separation concentration, separation is concentrated into slurry concentration up to 8 Baume degrees, then will be after level-one separation concentration
Pueraria lobata, which is slightly starched, carries out the second-order separation concentration, and separation is concentrated into slurry concentration up to 12 Baume degrees, after finally the second-order separation is concentrated
Pueraria lobata, which is slightly starched, carries out three-level separation concentration, and separation is concentrated into slurry concentration up to 17 Baume degrees.
Further improvement lies in that: speed of agitator is 300-400 revs/min in the step 7, and the pump power does not surpass
Cross 3kw.
Further improvement lies in that: remaining a small amount of pueraria lobata forms sediment in remaining sediment solution in stirred tank in the step 7
Slurry can purify out the pure slurries of a small amount of pueraria starch by the way that the secondary liquid of pipe is added.
The invention has the benefit that there is no any pollution, Guan Zhong by the secondary liquid of pipe that pure plant Guan Zhong is prepared
Liquid can be with the silt in rapid subsidence pueraria lobata slurry, and product is healthy and safe, does not contain chemical addition agent, and long-term consumption does not have body
Side effect, the method for preparing the secondary liquid of natural plants additive pipe is simple, easy to operate, easy to use, saves labor, save the cost,
Without carrying out multistage filtering and flushing, the nutritional ingredient in pueraria starch is remained to greatest extent, is suitable for large batch of pueraria lobata
The quick slurry of starch separates, while the method is also applied for the extraction of other kinds of radicant starch, passes through three fractions
