A kind of automatic breeding apparatus and method of spirulina
Technical field
The present invention relates to a kind of automatic breeding apparatus and method of spirulina.
Background technology
Spirulina is produced through the development of two more than ten years, and the specification production model of unified intensive, stdn, automatization is conducive to the lifting of whole industry.Centralized the production of the spirulina GAP production standard according to pharmaceutical raw material is carried out to management in the world, this is the key of guaranteeing quality product, is also the important directions developing at present; And the regulation and control that become more meticulous of production process have become the key link of improving the quality of products with economic benefit.
It is CN1426678 that the patent of automatic breeding aspect has publication number, title " indoor automatic breeding system ", disclose for cultivation biological cultivation is cultivated in indoor stepped culturing pool employing stage, make cultivation density increase and reduce space, and at any time with the water quality condition of water quality monitoring system monitoring culturing pool, make breeding water keep best state, can improve cultivation survival rate, increase cultured output.Publication number is CN1864474, name is called the patent of invention of " a kind of cultural method of spirulina ", discloses the cultural method of a kind of spirulina breeding barrel in booth, adopts enclosed industrial method cultivation, can Artificial Control solution temperature and light application time, improve output.
But current production process regulation and control, still rely on and observation and the operation of total man's work, lack the application of relevant electromechanical controlling device and automatic breeding.Traditional spirulina still adopts extensive style cultivation, integral production inefficiency.Cultivating spirulina footprint area is large, and industrial scale often reaches hundreds thousand of square metres, and artificial labour intensity is large.Particularly, for being that continuation is cultivated or gathering to lack to supply the method and apparatus of discriminating, aging spirulina is cultivated in continuation often, and so, the speed of growth is low, produces and there is no benefit; If by not yet arriving or in the early stage spirulina gather ahead of time of exponential growth, wasting to cultivate directly and drop into, do not obtain due benefit.Visible, the automatization of production technique is the important guarantee that reduces labor intensity, improves productivity effect.
Along with the widespread use of mechanize, automatization, particularly plant industry for the breeding of traditional agriculture, become and led industry forward position.By mechanize day by day replace artificial operation, make up labor force's wretched insufficiency; Reduce artificial error, reaching becomes more meticulous produces and management; Reduce manual operations, reduce the safety problem that directly has influence on product.Cultivation automatization is also the important symbol of this lifting industry.
Summary of the invention
The invention provides a kind of apparatus and method of automatic breeding of spirulina, solve the technical problem of above-mentioned existence.
The present invention be according to " screening culturing pool ecological index---determine and detect index---configuration of test set---detect online---comprise data feedback, set up the central control system of criterion and program output---executable operations " mathematical logic realize its technical scheme.Technical scheme is as follows:
An automatic breeding method for spirulina, main technique link comprises:
Screening culturing pool ecological index, the configuration of determining detection index, test set and online detection, master control system and executable operations link; Described master control system by data feedback, set up criterion and program is exported;
Described screening culturing pool ecological index comprises the five large indexs such as pH value, dissolved oxygen, chlorophyll, optical density(OD), turbidity.
Described regular inspection is really surveyed index: adopt YSI6600 Multifunctional water to detect instrument and carry out on-line determination pH value, dissolved oxygen, chlorophyll and turbidity at screening culturing pool; Adopt 721 spectrophotometric determination optical density(OD); Detected result and growth of spirulina platensis situation are compared, judge that the spirulina cultivated is whether in the exponential growth later stage and reached certain density, in view of the high correlation of turbidity and spirulina density, determine turbidity as whether to the detection index of collection period, the data and the spectrophotometer method that detect are compared, reach the scope that optical density(OD) is 0.75-0.85, be equivalent to according to 1 ton of nutrient solution, at every turn can output spirulina powder 0.9-1.05kg as comparison.
The operation of described master control system: arrive master control system by data feedback, set up criterion, the data of detection and culturing pool ecological index are compared, form different instructions.
Described executable operations is: if turbidity reaches the index of setting, belong under normal growth conditions, feedback information is exported, open in time the valve of gathering, start the algae liquid of cultivation pool to enter between collecting cart by pipeline, after having gathered, add in time nutrient solution, increase water level, enter next production cycle flow process; If turbidity does not change or can not reach the index of setting, belong under abnormal growth conditions, further gather the sample of cultivation pool, Source Tracing, changes algae kind or nutrient solution in time, regulates culture condition.
The present invention be conducive to realize spirulina standardization, production management becomes more meticulous.

Embodiment
embodiment 1
1, in experiment pool, screening and mensuration culturing pool ecological index: screening culturing pool ecological index comprises the five large indexs such as pH value, dissolved oxygen, chlorophyll, optical density(OD), turbidity.
2, determine and detect index: detected result and growth of spirulina platensis situation are compared, judge that the spirulina cultivated is whether in the exponential growth later stage and reached certain density, in view of the high correlation of turbidity and spirulina density, determine turbidity as whether to the detection index of collection period.The data and the spectrophotometer method that detect are compared, reach the scope that optical density(OD) is 0.75-0.85, be equivalent to according to 1 ton of nutrient solution, can output spirulina powder 0.9-1.05kg (it be 3.0 days according to the interval of gathering as comparison at every turn, be equivalent to 120 times/year, year output reaches 108-126kg/year so).
3, first in experiment pool, the configuration of test set detects with online: the online automatic detection device that adopts turbidity that detects, adopts YSI6600 Multifunctional water to detect instrument on-line determination pH value, dissolved oxygen, chlorophyll, turbidity; Adopt 721 spectrophotometric determination optical density(OD).
4, the operation of master control system: arrive master control system by data feedback, set up criterion, the data of detection and culturing pool ecological index are compared.
5, executable operations: if belonged under normal growth conditions, the index that reaches setting of turbidity, feedback information is exported, open in time the valve of gathering, start the algae liquid of cultivation pool to enter between collecting cart by pipeline, after having gathered, add in time nutrient solution, increase water level, enter next production cycle flow process; If turbidity does not change or can not reach the index of setting, belong under abnormal growth conditions, further gather the sample of cultivation pool, Source Tracing, changes algae kind or nutrient solution in time, regulates culture condition.
