The technological process of medicine low temperature heating unit

The heat transfer medium of the whole circulation system of the medical low temperature heating unit is a fully closed circulation.
The circulation system has a liquid expansion container.
The expansion container and the liquid circulation are independent systems.
The expansion container does not participate in the liquid circulation, but is only a mechanical connection
.

Even in the case of high temperature operation, the heat transfer medium in the expansion vessel will not be higher than the set value
.


1.
The whole cycle is airtight, there is no oil mist volatilization at high temperature, the heat transfer oil is not easy to be oxidized and browned; it is not easy to absorb water vapor in the air at low temperature; prolong the service life of heat transfer oil
.

2.
This equipment has self-diagnosis function, freezer overload protection, high pressure pressure switch, overload relay, thermal protection, high pressure protection device for circulation system when heating at high temperature, etc.
, to fully guarantee the use; 3.
Adapt to the control system in the chemical reaction process In the process of continuous adjustment of PID parameters to give the process control temperature and response time, this process is achieved through effective multi-directional measurement of temperature, temperature change and temperature change rate
.

　　4.
With the function of correcting the external circulation and internal circulation temperature probe PT100
.

　　5.
It can display the temperature set value and actual value at the same time, as well as the over-temperature alarm value
.

The heat load during the temperature change of the entire system of the pharmaceutical low-temperature heating unit is the total amount of heat transfer oil in the entire system (mainly) + the reactants in the reactor.
The larger the volume, the smaller the effective power used in the kettle, and the reaction in the kettle.
The slower the speed response and rate of heating and cooling of the material
.

It can realize continuous temperature rise and fall, and use compressor technology to operate under high temperature and high pressure, which greatly improves the cooling rate and saves experimental time and energy
