Technical Field
The utility model relates to a temperature measurement agitating unit specifically is an online temperature measurement agitating unit, is applicable to the online temperature measurement stirring of medicine class instruments such as medicine dissolving-out appearance.
Background
The temperature of the solvent has a critical role during the dissolution test. In the whole (dissolution) stirring experiment process, in order to ensure the reliability of the dissolution experiment, other devices which interfere the dissolution process except the stirring device in the dissolution cup are not needed to be arranged, otherwise, the dissolution result is influenced. When a traditional dissolution instrument is used for performing a dissolution experiment, in order to ensure the accuracy of the experiment, the temperature of the solvent can be fed back only by monitoring the temperature of the water bath, or the temperature of the solvent can be measured for a short time during sampling, so that the temperature of the solvent in the traditional dissolution experiment process is not monitored in real time. Because the dissolution cup is arranged between the solvent and the water bath for isolation, the dissolution cup has certain thermal resistance, and the thermal resistance of all the dissolution cups is inconsistent, the temperature of the water bath is not equal to the temperature of the solvent, namely the real-time temperature of the water bath does not represent the real-time temperature of the solvent. In summary, when the conventional dissolution apparatus performs a dissolution experiment, the sampling of the solvent temperature is performed only during the sampling, and the sampling frequency is limited, which results in insufficient solvent temperature monitoring data; meanwhile, the response time of the temperature probe is slow, so the temperature probe needs to be immersed in the solvent for a certain time during solvent temperature sampling, and the temperature probe is interfered in the time period, thereby influencing the dissolution experiment.
