Description
Technical field
The utility model relates to a kind of inoculation protection device, for the flame inoculation of fermentation tank, belongs to technical field of chemical production equipment.
Background technology
It is pharmaceuticals industry development trend, the research to biological enzyme agent from now on that biological enzyme produces antibiotic, is premise and the basis of development enzyme process antibiotic.The industrialization of 7-ACA production biological enzyme agent is the key technology of development enzyme process antibiotic, is conducive to promoting China's pharmaceuticals industry in production technology industry, the raising of Fermentation Engineering level of industry.
D-AAO is a kind of exemplary protein enzyme with flavin adenine as prothetic group, catalytic reaction substrate is had to alloisomerism selectivity and the broad spectrum activity of height, be widely used in the amino acid whose qualitative and quantitative analysis of D-, biology sensor, l-amino acid and the production of 2-ketoacid；Its most important value, is to be applied to two-step method to produce 7-amino-cephalosporanic acid (7-ACA).With cephalosporin as raw material, D-AAO oxidation cephalosporin generates Glularyl-7-amino-cephalo-alkanoic acid (GL-7-ACA), then generates 7-ACA at GL-7-ACA ACY catalysis deacylated tRNA.
The production process of D-AAO mainly includes seed culture, ferments, extracts and the several workshop section of immobilization, and specific embodiment is: (1) will contain and thaw under seed-bearing deep cooling pipe normal temperature, put into seed bottle, access seeding tank and cultivate after screening；(2), after cultivation seed reaches culture transferring condition, move into fermentation tank, ferment in the fermentation tank containing culture medium, until it is qualified to ferment；(3) qualified fermentation liquor is crossed the separation of solid and liquid of multiple working procedure, obtains pure containing enzyme feed liquid；(4) carrier is put into containing being fixed in enzyme feed liquid, immobilization complete after through washing, drain, get product.
In fermentation workshop section, seeded process each time will be carried out under the protection of flame; existing flame protection inoculation be around the inoculation mouth of fermentation tank cover placement pyrosphere, then from the centre of flame, bacterial classification is poured in fermentation tank, after cover fermentation tank inoculation mouth; take pyrosphere away, start fermentation.At least need a staff to utilize instrument to clamp pyrosphere in seeded process, waste manpower and materials, easily cause security incident simultaneously.And if pyrosphere is not being placed on around fermentation tank inoculation mouth of level, the flame inoculating mouth during inoculation has the most uneven phenomenon of height, easily brings in fermentation tank by miscellaneous bacteria, forms microbiological contamination, ultimately result in and ferment unsuccessfully.
Utility model content
The purpose of this utility model is to provide the flame inoculation protection device of a kind of simple in construction, ensures even flame, improve success rate in seeded process.
For achieving the above object, the utility model adopts the following technical scheme that
A kind of flame inoculation protection device; including being co-axially located at the connecting tube of fermentation tank inoculation mouth, being sleeved on the top cover on connecting tube top and for placing the platform of pyrosphere; described platform includes the transverse slat of polylith horizontal positioned; polylith transverse slat circumference uniform distribution centered by inoculation mouth is arranged on the top of connecting tube lateral wall, and one end of transverse slat is fixedly connected on inoculation mouth lateral wall；The other end suspension of transverse slat, described top cover is arranged the handle of the pole shape of convenient gripping by connector.
Above-mentioned flame inoculation protection device, described connector includes three blocks of square plates, and three pieces of square plate the most end to end formation U-board, the two ends of U-board are arranged on the lateral wall of top cover by bolted splice.
Above-mentioned flame inoculation protection device, arranges a funnel with the coaxial of the connecting tube of inoculation mouth connection.
Above-mentioned flame inoculation protection device, described top cover extends radially through and arranges multiple pore.
The beneficial effects of the utility model are:
Flame inoculation protection device simple in construction described in the utility model, easy to use, after pyrosphere is placed on the platform being made up of transverse slat, top cover is taken off, inoculate.After having inoculated, top cover is built.Use the utility model to improve the success rate of inoculation, reduce labour intensity, it is ensured that the safety of staff, decrease production cost.
Top cover and handle are coupled together by connector, prevent in use staff injured.Connecting tube arranges funnel in the position being connected with inoculation mouth so that bacterial classification can slowly fall, and improves success ratio of inoculation.
