Detailed ways

The device for producing casein automatic dissolving includes a static mixer (29), the static mixer is connected with a frequency conversion material pump (28) and a frequency conversion alkali pump (13), and the special dissolution pipeline (32) includes a pH electrode (31 ), hot water tank (33), pH electrode (34), pH electrode (35), it is characterized in that: described pH electrode (31) is connected after static mixer, described pH electrode (34) and pH electrode ( 35) Connect to the 1/3 and 2/3 of the special dissolving pipes (32) respectively. The special dissolving pipes are placed in the hot water tank (33) to maintain a constant dissolving temperature. After the pH electrode (34) Be connected with lye inlet (36), be connected with lye inlet lye inlet (38) before pH electrode (35), be connected with electromagnetic valve (37) before described lye inlet (36), in described lye An electromagnetic valve (39) is connected before the inlet (38), and a secondary dissolution pipeline (41) and a one-way valve (42) are connected behind the special dissolution pipeline, and the pH electrode on the pipeline is connected with the PLC automatic control module (40) . the

When in use, pre-set the required pH value of the dissolved material and the upper and lower limits of the variation range during the automatic pipeline dissolution process, and then set the pH value of the material mixed with the lye to be 10-10.5%, and the temperature to be 53-55°C , The flow of material and alkali is automatically adjusted and controlled by the frequency conversion pump according to the dynamic change of pH value. Automatic pipeline dissolution process: the pH value of the material and lye after passing through the static mixer 29 is monitored by the pH electrode 31 installed in the pipeline, and the signal is fed back to the frequency conversion alkali pump 13 through the PLC system 40, and its speed is adjusted to adjust the lye and the mixed material The purpose of pH is to stabilize the pH of the mixed material between 9.5-10.0. After the lye and the material are mixed, they enter the special dissolution pipeline 32 installed in the constant temperature water tank 33 for automatic pipeline dissolution. The electrodes installed on the special pipeline 34 and electrode 35 online monitor the pH change in the pipeline dissolution process, and control the opening and closing of the solenoid valve 37 and solenoid valve 39 through the PLC system 40, so that the lye enters the pipeline at points 36 and 38 to automatically adjust the dissolved pH. The purpose is to quickly dissolve the material under the conditions of constant dissolution temperature and dissolution pH, and realize the automatic production of the dissolution section of casein production. The automatic pipeline dissolution is controlled by the PLC system 40 . the

If the material is not completely dissolved, it will not be able to pass through the check valve 43 and be dissolved again through the secondary dissolution pipeline 42. Many experiments and researches have shown that the material is completely dissolved at this time, and the material liquid will enter the centrifugal degreasing section. the
