By dispenser of the present invention, realize microbiological culture media preparation, its method comprises the steps:
(1) preparing tank and accessory thereof are carried out sterilising treatment;
(2) preparing tank, substratum bag are connected with controller case, the rising pipe of the feed-pipe of preparing tank with substratum bag is connected, the water inlet pipe of described substratum bag is connected with the water outlet of described controller case, the water-in of described controller case is connected with water source by pipe connecting, and described pipe connecting is arranged on the pump head of described peristaltic pump;
(3) start peristaltic pump, the water at water source is entered controller case from the water-in of controller case and is heated by interchanger, discharged by water port simultaneously;
(4) after water temperature reaches preset temp, water port is closed automatically, and the water outlet of controller case is opened automatically, and heating water enters substratum bag;
(5) when the water yield injecting substratum bag reaches the volume of dissolution of setting, peristaltic pump stops;
(6) disposable injection preparing tank after the substratum in substratum bag all dissolves or reaches mixing state;
(7) again start peristaltic pump, the hot water after being heated by interchanger is directly injected in preparing tank through described substratum bag, until the water yield in preparing tank reaches preset value;
(8), after having prepared, the feed-pipe of preparing tank and the pipe clamp of discharge nozzle is closed.
Detailed process is as follows: after startup, peristaltic pump entry into service, starts to pump into distilled water, and when distilled water flows through interchanger 71, water is heated, and when water temperature does not reach the substratum solvent temperature of setting, water is discharged from water port 26, can directly discharge or be back to water butt; When water temperature reaches after tank water temperature, water port 26 is closed automatically, and water flows out from water outlet 28,611 flows to substratum bag 6 by the road.After the water yield pumped into reaches the volume of dissolution of setting, peristaltic pump automatic pause.In this stage, along with current enter substratum bag, substratum starts to dissolve, and completely after mixing, disposablely imports to preparing tank until substratum in water.If wish that whole process for preparation is unmanned intervention completely, then substratum bag can be placed on a vibrator, vibrator can place the position higher than tank deck water inlet pipe 19, and vibrator is controlled by console controller, accelerates substratum dissolve and mixing by vibration.When the magnetic valve 621 on pipe connecting 192 is opened, the substratum after dissolving flows into preparing tank.Another kind of mode adopts and manually rocks substratum bag, even both hands rubbing substratum bag, accelerate dissolution.After substratum dissolves, unclamp pipe clamp 621, open pipe clamp 632, utilize the air pressure inside and outside pneumostome 63 equilibrated Medium bag, by disposable for culture medium solution importing preparing tank.
After culture medium solution imports preparing tank, again start the peristaltic pump of time-out, continue to add water in tank through substratum bag, and rinse culture medium solution residual in substratum bag, or increase once intermittent flushing operation, reduce medium component residual in substratum bag as far as possible.
Once interchanger 71 starts heating schedule, then start the heating schedule of heating in water bath case 73 simultaneously, after the water temperature in heating in water bath case 73 reaches set(ting)value, maintain this temperature and start chuck circulation.After the accumulative water yield pumped in tank reaches and melts volume (be about about 20% that culture volume is always prepared in budget), peristaltic pump automatic pause, magnetic agitation motor starts automatically, and run under the rotating speed preset, and the heating in water bath case 73 flowing through jacket water (J.W.) starts heating schedule automatically, rise to temperature in tank always and reach agar melt temperature, and maintain several minutes (can be determined by test, so that agar melts completely).Automatically reduce chuck water temperature afterwards, with maintain substratum temperature in tank setting moisturizing temperature value (about 60 DEG C, can be determined by test, keep agar in tank and packing time be in melting state always).When temperature in tank reaches after predetermined holding time in agar melt temperature value, peristaltic pump is autoboot again, and starts the alternating temperature program of interchanger simultaneously, to keep moisturizing temperature consistent with holding temperature in tank (about 60 DEG C).If preparing tank is the individual layer tank body not having chuck, then the hot-plate 21 of controller upper central position can be adopted to carry out substratum in heating tank.
When after the preparation cumulative volume that the distilled water pumping into preparing tank reaches default, peristaltic pump shuts down.If in tank, temperature is higher than the temperature required during substratum packing during moisturizing, then heating in water bath case starts cooling process automatically, the temperature needed during to reach packing.If adopt hot-plate 21 mode to heat preparing tank, then by regulating hot-plate to change temperature in tank.
When reaching predetermined preparation cumulative volume in preparing tank and when in tank, temperature reaches packing holding temperature, controller all can send information, and pipe clamp 621 and 612 can clamp by operator, or adopts magnetic valve to substitute pipe clamp, automatically closes.The temperature needed during equipment maintenance packing and rotating speed, until packaging operation terminates.
Equipment can carry out parameter modification and confirmation when running at any time, performs new operational requirement.
The timing node of the heating module start and stop of process for preparation and temperature value, peristaltic pump start-stop time node and rotating speed and accumulation at that time at that time add the information such as the volume of distilled water and all can go on record.
