Background technology
Existing measuring apparatus is divided continous way metering and discrete type metering.Electromagnetic flowmeter is adopted in continous way metering, and mass flowmeter etc. measure, and precision is higher, but price is more expensive, then can reduce precision as bubble etc. is arranged in the feed liquid, particularly in fermentation industry, also must use expensive continuous variable valve.
Discrete type metering " measuring cup type " is representative with " three-valve system ", (see figure 1), measure and cup typely apply for many years at pharmaceutical industry, obtain effect preferably, but because the metering of feed supplement is a volume with cup is that unit calculates, because influence of various factors such as tank pressure, foaming make and lack accuracy with the cup number as the unit of metering in the sweat." three-valve system " as shown in Figure 1.There is a big diaphragm at the V3 middle part, can be shifted to the left and right; When it bloated, the right cavity formed negative pressure, made material inspiration (this moment, retaining valve V1 opened, and V2 closes); The diaphragm of V3 resets left and V1 closes subsequently, and V2 opens, and simultaneously feed liquid is extruded, and covers fermentation tank; Go round and begin again, finish the feed supplement action.Think that in theory the material of each inspiration all is identical,, just can know the feed supplement amount as long as know the number of times of action, but during actual the use, since the pressure of import and export, influences such as the air in the feed liquid, foam, and measuring accuracy is lower.
In the biofermentation industry, the optimization of sweat is in the optimizing fermentation of core with cellular metabolism stream particularly, and the control of flow of material directly has influence on the fermentation net result.
Yet the control of flow of material at first will have high-precision feed supplement metering system.Existing feed supplement metering system measuring accuracy can't adapt to the optimization of sweat.In lab scale, pilot experiment, the precision of feed supplement metering directly has influence on the accuracy that zymotechnique amplifies.
Summary of the invention
At the lower defective of measure control precision of existing feed supplement metering control, technical problem to be solved in the utility model provides a kind of high-precision supplementary food weighing and metering control device.
The technical solution of the utility model is, a kind of supplementary food weighing and metering control device, and it comprises feed supplement cup, valve system, fermentation tank, feed supplement jar, is characterized in that it also comprises:
A weighing system, this weighing system comprise LOAD CELLS, cantilever, fixed support, feed supplement cup.LOAD CELLS links to each other with support by cantilever, and the feed supplement cup links to each other with LOAD CELLS, weighs up feed supplement weight in the feed supplement cup by LOAD CELLS.
An electronic monitoring and control system, it comprises input/output module, warning and display module, keyboard and mouse touch screen, comparer, setter, CPU and feed rate controller.
Described feed supplement cup upper end links to each other with charging valve, admission valve with the pipeline of feed supplement jar by flexible pipe, to realize the function of charging and admission sterilization, feed supplement cup upper end also links to each other with the valve that is connected with the fermentation tank gas exhaust duct with the fermentation tank gas exhaust duct by flexible pipe, the pressure behind this valve opening in the feed supplement cup and the pressure equilibrium of fermentation tank guarantee that feed liquid flows into fermentation tank by potential difference; The following outlet of feed supplement cup links to each other with the feed supplement valve with the pipeline of fermentation tank by flexible pipe, to finish feed supplement in fermentation tank.
Described feed supplement cup links to each other with LOAD CELLS, and LOAD CELLS links to each other with support by cantilever, weighs up feed supplement weight in the feed supplement cup by LOAD CELLS.
Described supervisory system, it will be sent to comparer by the A/D modular converter in the input/output module by the detected feed supplement weighing result of LOAD CELLS and compare with the set-point that setter is sent here, revise the deviation of feed supplement amount by the feed rate controller in CPU, this deviate is opened corresponding valve by the control of D/A modular converter and is carried out feed supplement.
Because the utility model comes the feed supplement amount by weighing device, therefore, of the present utility model beneficial effect is arranged is that the feed supplement degree of accuracy is up to 0.5%, for optimizing fermentation and amplification provide reliable assurance.
