Description
Technical field
The present invention relates to laver processing, be specifically related to cleaning device and cleaning method thereof in the main laver process.
Background technology
Laver is a kind of algae of propagating artificially, has higher business and is worth, and be a kind of pollution-free food.Grow in the ocean because laver is the nature breed, therefore in the laver of gathering, have impurity such as mud and sand, so in the laver process, at first must clean up to laver.Traditional laver cleaning method is: utilize manpower with laver in the ocean or fill to swing in the pond of seawater and wash, impurity in the flush away laver, this needs more manpower and time, and the cleaning benefit is not high, and whether clean up relevantly, often be not easy to clean up with human factor; At present in the processing of industrialization laver, adopt special cleaning device to clean laver, cleaning device comprises service sink, in service sink, be provided with electric blender, bottom in service sink is provided with screen pack, bottom at service sink is provided with sewage draining exit, cleaning method is a service sink of an amount of laver being put into the mixing water that fills seawater or seawater and fresh water, starts mixer, utilizes the stirring laver that the impurity in the laver is separated with laver, impurity sinks at the bottom of the pond, reach the purpose of cleaning impurity, stirring finishes, and with pump laver is extracted into down in one manufacturing procedure and further processes, open sewage draining exit then, impurity is just discharged outside the pond; For the impurity in the laver is cleaned up, often needing to change water cleans once again, perhaps laver being changed over to another cleaning device cleans once again, utilize above-mentioned cleaning device to clean laver, though reduce manpower and improved the cleaning benefit, in whipping process, laver is stirred machine winding and broken easily, bring difficulty to stirring, also caused form breakage of laver and the operating loss of laver, reduced the laver quality of processing.Contain harmful heavy metal element in addition in the laver, be generally 0.05-0.50mg/kg (with dry weight basis), ediblely contain the higher laver of heavy metal for a long time, can cause heavy metal poisoning disease as the Pb content of laver.
Summary of the invention
Technical problem to be solved by this invention provides the cleaning device in the laver process of a kind of complete form that can keep laver and less operating loss.
Another object of the present invention provides the cleaning method in a kind of laver process of utilizing above-mentioned cleaning device, and this method can obtain complete form and the few laver of business composition loss, can reduce the content of beary metal in the laver converted products again.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: the cleaning device in the main laver process, comprise service sink, also comprise an auxiliary service sink identical with described service sink volume, described service sink and described auxiliary service sink are height setting, be interconnected by water pipe between described service sink and the described auxiliary service sink, the import of described water pipe is arranged on the place, close bottom of described service sink, the outlet of described water pipe is arranged on the center near described auxiliary service sink, the horizontal plane of the outlet of described water pipe is not higher than the horizontal plane of the import of described water pipe, described water pipe is provided with valve, be provided with a plurality of micropore air inlets around pool wall on the described service sink, be provided with a plurality of assistant micropore air inlets around pool wall on the described auxiliary service sink.
Bottom at described service sink is provided with sewage draining exit, is provided with screen pack between the import of described water pipe and described sewage draining exit.
Be provided with auxiliary sewage draining exit in the bottom of described auxiliary service sink, between the outlet of described water pipe and described auxiliary sewage draining exit, be provided with the aided filter net.
Described micropore air inlet is set to 6～12, is arranged on the top near described screen pack.
Described assistant micropore air inlet is set to 6～12, is arranged on the top near described aided filter net.
Between the outlet of described water pipe and described aided filter net, be provided with Pai Caikou.
Cleaning method in the one main laver process comprises the steps: 1), close the valve of sewage draining exit and water pipe, clean seawater is injected in the service sink, by weight 1:10～30, fresh laver is joined in the clean seawater again; (2), supply gas, bubbling 10～30 minutes left standstill 3～6 minutes then from the micropore air inlet; (3), close auxiliary sewage draining exit and Pai Caikou, open the valve of water pipe, laver in the service sink and part seawater just flow in the auxiliary service sink, after laver all flows into, close the valve of water pipe, add fresh water in auxiliary service sink, the weight ratio that makes laver and water is 1:10～30, and adding weight again is water volume 3～15g/m
3EDTA-Na salt; (4), supply gas, bubbling 10～30 minutes left standstill 8～12 minutes then, opened Pai Caikou, and laver is discharged to the next process from row's dish mouth from the assistant micropore air inlet; EDTA-Na salt can with the heavy metal complexing, make the present invention can reduce by 0.5～3.0 times than the content of beary metal in the existing cleaning method laver, EDTA-Na salt can also with the inorganic As huge legendary turtle cooperation usefulness in the laver, reduce the content of As.
Drain the laver of surperficial moisture content after above-mentioned fresh laver is meant and gathers, or the dried laver of preliminary working that cleans up of end also drains the laver of surperficial moisture content after being soaked in water.
Compared with prior art, the invention has the advantages that at the other lower auxiliary service sink in position that is provided with of service sink, be interconnected by water pipe between service sink and the auxiliary service sink, water pipe is provided with valve, the horizontal plane of the outlet of water pipe is not higher than the horizontal plane of the import of water pipe, on service sink, be provided with a plurality of micropore air inlets around pool wall, on auxiliary service sink, be provided with a plurality of assistant micropore air inlets around pool wall, when in service sink, cleaning laver like this, utilize the micropore air inlet to supply gas in the water, make the drum bubble, thereby laver is fluctuateed in water, reach the purpose of the most of impurity of flush away, utilize the water pipe that is communicated with service sink and auxiliary service sink again, the laver that cleaned at service sink is flow in the auxiliary service sink, utilize the assistant micropore air inlet to supply gas equally and make the drum bubble, impurity on the further flush away laver, this has just solved when utilizing mixer to clean laver at present, laver is stirred machine easily and twines and broken problem, thereby has kept the complete form and the nutritive loss that has reduced laver of laver; Also simplify simultaneously the operation that will take out with pump twice cleaning of laver, saved the energy consumption that to take out with pump; Therefore the present invention is a kind of reasonable in design, simple in structure, has the complete form and the less operating loss that keep laver, and the cleaning device in the laver process that can cut down the consumption of energy.Cleaning method of the present invention removes and utilizes above-mentioned cleaning device, can clean and obtain complete form, and the few laver of business composition loss has added EDTA-Na salt in addition in cleaning, make that the content of beary metal in the laver obtains bigger reduction.
