Design Of The Control System On The Enzymatic Membrane Reactor

The enzymatic membrane reactor that is an important application form of activator—enzyme in industrial manufacture is an equipment of production or experiment. The enzymatic membrane reactor that concentrated separation, purification and recycle is an enzymatic reaction-membrane separation setting.Based on the experiment, chemical institute has designed the equipment of scale-up experiment"the continuous enzymatic membrane reactor"that product casein phosphopepetides (CPPs )in the laboratory. It has confirmed the step and parameter of the operation, finished the experiment of the batch of 20L and scale-up experiment of 40L continuous enzymatic reaction-membrane separation technique. But because of their handcraft in the production, not only workers'intensity is great, but also the precision of working parameter is hard to be ensured.In the preparation process of CPPs, the temperature and pH impact on enzymatic activity which affect greatly rate of reaction. In order to achieve intelligent production and great efficiency, it is essential to measure and control accurately in real time to the temperature, pH and volume of the material in the continuous enzymatic membrane reactor.On the base of the testing setting - the continuous enzymatic membrane reactor which is developed by chemical institute, the text realizes to measure, display and control automatically to continuous production of CPPs. The content included:1.To realize automatic measure and control to the temperature, pH and volume of production in the continuous enzymatic membrane reactor.2.To measure automatically absorbency and weight of the finished product.3.To design, install and debag the electrical setting.4.To contrive the shape of console, the display panel, the layout of the interior element and to fix them.5.To finish the communication between the single chip and the computer on the base of the multi-node network control of PC.
