The method comprises the following steps of feeding carbon sources in batches in a carbon source dissolving tank; continuously pumping water into the carbon source dissolving tank through a high-pressure water gun to circulate and dissolve the carbon sources inside the tank; opening a conveying pump between the carbon source dissolving tank and microorganism biomass culturing ponds, and pumping the carbon sources from the carbon source dissolving tank to the corresponding culturing pond through conveying pipes; washing and pumping water into the carbon source dissolving tank through the high-pressure water gun to ensure dissolution of solid inside the carbon source dissolving tank during feeding; washing the carbon source dissolving tank and the conveying pipes to ensure that all the carbon sources enter the corresponding culturing ponds; setting a plurality of the culturing ponds, conveying the carbon sources to the designated culturing ponds through opening and closing of valves. According to the pipe conveying method of the solid carbon source feeding of the microorganism biomass cultivation, by means of the high-pressure water gun and carbon source batch feeding combined mode, the carbon sources become flowing and easily-conveyed turbid liquid, so that an efficient carbon source feeding mode which achieves high security and ensures high purity of finish products can be obtained.
Description
Technical field
The present invention relates to microbiological industry production technical field, relate in particular to pipe transportation technology field in microbiological industryization production.
Background technique
Microbial biomass is that the microorganism of micro-algae and bacterium mixes group, and described mixing group is the floc of micro-algae, diatom, yeast, fungi, protista, microplankton and bacterium.Micro-algae is used as the feed of mollusc, crustacean class and some fish in aquaculture, and the feed of the zooplankton using for aquaculture food chain.Micro-algae has played key effect in prawn culturing.Can be used as the feed additive of crustacean after dry containing the microbial biomass floc sedimentation of micro-algae, but main difficulty is to be difficult to obtain stable yield, cheap product.
The production technology of the microorganisms such as micro-algae, spirulina, diatom is generally to use suitable carbon source, nutrient raw material to pass through under certain hour and condition and breed growth in certain container, and wherein container has exploitation formula, closed.Produce from industrially scalable, the cultivation of microbial biomass needs the conditions such as a large amount of water bodys, oxygenation, aeration, is the major obstacle of current micro-organisms and stablize, produce cheaply.
Publication number is that the Chinese invention patent of CN102016001A kind, the consumption to nutriment, carbon source is described in detail, but do not introduce how efficient, low cost input, and one of important content of realization of industrialization is realized automation, mechanization, standardization by master operation exactly, the realization of industrialization that raw material is thrown in is an important process, but is also not solve in this patent.
Generally carry out in the mode such as road transport, conveyor belt for the input of the carbon source class solid material of carrying in patent at present.If feed factory is for the use of corn, soybean products, be generally to use the modes such as transport vehicle, feed bin, belt conveyer, lift to supply material for mixing apparatus.Its shortcoming be equipment investment large, be suitable for the material that unit weight is good compared with high fluidity, be not suitable for thering is other the building of culture pond of seawater of corroding metal.
As used bagasse as raw material in paper industry time, realize the delivery of material with equipment such as adhesive tape conveyor, flight conveyer, blowers.Also exist input huge, easily by defects such as seawater corrosions.
