Description
(5) УСТРОЙСТВО дл АВТОМАТИЧЕСКОГО КОНТРОЛЯ ВЛАЖНОСТИ В СУБЛИМАЦИОННОЙ СУШИЛКЕ(5) DEVICE FOR AUTOMATIC MOISTURE CONTROL IN SUBLIMATION DRYER
Изобретение относитс к сушильной технике и, в частности, к автоматизации сублимационной сушки.The invention relates to a drying technique and, in particular, to the automation of freeze-drying.
Известны устройства дл автомаУического контрол влажности в сублимационной сушилке, снабженной нагревателем , содержащие тепломер и дифференциатор с усилительно-преобразовательным блоком, однако известное устройство недостаточно точно позвол ет измерить влажность 1 .Devices for automatic humidity control in a freeze dryer equipped with a heater are known, which contain a heat meter and a differentiator with an amplifier-converter unit, but the known device does not accurately measure the humidity 1.
Цель изобретени - повышение точности контрол влажности.The purpose of the invention is to improve the accuracy of humidity control.
Поставленна цель достигаетс тем, что устройство содержит дополнительный тепломер, второй дифференциатор и исполнительный механизм, св занный через усилительно-преобразовательный блок и второй дифференциатор с первым дифференциатором, который подклю чен к дополнительному тепломеру, причем тепломеры соединены дифференциально .The goal is achieved by the fact that the device contains an additional heat meter, a second differentiator and an actuator connected through an amplifier-converter unit and a second differentiator to the first differentiator, which is connected to an additional heat meter, with heat meters being differentially connected.
На чертеже представлена схема предлагаемого -устройства Устройство содержит тепломер 1 и .дополнительный тепломер 2, соединенные с нагревателем 3 посредством резисторов 4 дифференциатора 5, диффере |циатор 6, усилительный преобразо|Вательный блок 7 и исполнительный механизм 8.The drawing shows the scheme of the proposed device. The device contains a heat meter 1 and an additional heat meter 2 connected to the heater 3 by means of resistors 4 of the differentiator 5, a differential 6, an amplifying conversion | Vny unit 7 and an actuator 8.
О Устройство работает следующим образом .О The device works as follows.
На тепломер 1 устанавливают сушильный материал, который подогревают нагревателем 3. Сигнал, поступающийOn the heat meter 1 install the drying material, which is heated by the heater 3. The signal coming
15 с тепломеров Т и 2 в дифференциатор , определ ет скорость изменени подводимого теплового потока, дифференциатор S определ ет ускорение изменени указанного потока по достиже2d нии заданного значени управл ющего сигнала после дифференциатора 6, усилительно-преобразовательный блок срабатывает , выключа нагреватель.15 s of heat meters T and 2 into the differentiator, determines the rate of change of the input heat flux, differentiator S determines the acceleration of the change of the indicated flow by reaching 2d of the specified control signal after differentiator 6, the amplifier-transducer unit is activated by turning off the heater.
Таким образом, предлагаемое устройство позвол ет с высокой точностью контролировать влажность в сублимационной сушилке.Thus, the inventive device allows to control the humidity in a freeze dryer with high accuracy.
