(54) СИСТЕМА АВТОМАТИЧЕСКОГО УПРАВЛЕНИЯ ПРОЦЕССОМ НОРМАЛИЗАЦИИ МОЛОКА ПО ЖИРУ В ПОТОКЕ(54) SYSTEM OF AUTOMATIC CONTROL OF THE PROCESS OF NORMALIZATION OF MILK ON FAT IN A FLOW
15 и трубопроводом 16 возврата. Система автоматического управлени процессом нормализации молока по жиру в потоке работает следующим образом. Первый контур регулировани не зависиМО от режима работы обеспечивает посто нство расхода потока цельного молока и работает по посто нному заданию. Задача управлени сводитс к управлению производительностью потока обезжиренного молока в зависимости от жирности цельного. Эта зависимость имеет вид15 and return pipe 16. The system of automatic control of the process of milk normalization in fat in the stream works as follows. The first control loop, regardless of the mode of operation, ensures the constancy of the flow rate of whole milk and operates according to a permanent task. The management task is to control the flow rate of skim milk depending on the fat content of the whole milk. This relationship is
,(), при этом к - J гдеЖс, жирность потока нормализован ного молока; Жуц - жирность цельного молока; Qg - производительность потока обезжиренного молока; QIA - производительность потока це ного молока. С датчика 11 жирности поступает сигнал, пропорциональный жирности цельнхэго молока, в линейный усилител 12, куда также с блока 13 задани по тупает сигнал, пропорциональный жир ности нормализованного молока. Кроме того, с выхода блока 13 за дани на вход регул тора коэффициен та усилени линейного усилител 12 поступает сигнал, пропорцией ал ьньлй отношению расхода цельного молока к жирности нормализованного молока, т.е. К-а /ЖсмНа входе линейного усилител 12 сигнал, пропорциональный заданному значению жирности нормализованного молока, вычитаетс из сигнала, проп ционального жирности цельного молок f6, (), at the same time k - J where ZH, fat content of the flow of normalized milk; ZHUZ - fat content of whole milk; Qg - skimmed milk flow rate; QIA is the whole milk flow rate. A signal proportional to the fat content of the whole milk is sent from the fat sensor 11 to the linear amplifier 12, where a signal proportional to the fat content of the normalized milk is also received from the task block 13. In addition, from the output of block 13, a signal is sent to the input of the gain control of the linear amplifier 12, the ratio of the total ratio of the consumption of whole milk to the fat content of normalized milk, i.e. The KA / ZSHM at the input of the linear amplifier 12 signal, proportional to the specified fat content of normalized milk, is subtracted from the signal, the proportional fat content of whole milk f6
и полученна разность, усиленна в К раз, пропорциональна необходимой дл обеспечени нормализации производительности потока обезжиренного молока, поступает на вход вторичного прибора 8 второго контура регулировани , обеспечива стабилизацию производительности потока обезжиренного молока .and the resulting difference, increased by a factor of K, is proportional to that required to ensure the normalization of the performance of the skimmed milk flow, is fed to the input of the secondary device 8 of the second control loop, ensuring the stabilization of the skimmed milk flow rate.
