Problems solved by technology

But this invention does not solve the problem of cleaning management of the water bath of the dissolution apparatus
The minimum pore size of PP cotton and activated carbon is usually a few microns, which cannot guarantee the complete retention of particles. Ultraviolet sterilization is less effective for continuously flowing large amounts of water.
In addition, due to the huge amount of water in the water bath (usually dozens of liters), it is inefficient to slowly replace the liquid in the water bath by in-line filtration, and it is difficult to completely replace it

Embodiment 1

[0030] Periodic re-filtering: In the period set by the user, the water release procedure is first performed, and then the water addition procedure is performed, so that it is performed regularly.

[0031] The dissolution apparatus is working: the three-way solenoid valve S2 is connected to A (A->C), the three-way solenoid valve S3 is connected to A (C->A), the water in the water bath passes through the flow meter F2 and the three-way solenoid valves S3 and S2 , through the dissolution apparatus circulation pump 15 and the online heating unit 16, return to the water bath from the dissolution apparatus water bath inlet, and maintain the normal heating water circulation of the dissolution apparatus.

[0032]Cleaning mode: first add water until the water bath is nearly full, then the controller sends a cleaning command to the small submarine cleaning robot, and the small submarine cleaning robot performs traversal cleaning on the water bath. After cleaning, it executes the water di...

Description

technical field [0001] The invention relates to a water bath management device, which belongs to the fields of medicine, food and chemistry, in particular to a water bath management device for a dissolution apparatus. Background technique [0002] Dissolution refers to the rate and degree of dissolution of active pharmaceutical ingredients from preparations such as tablets, capsules or granules under specified conditions. It is an important indicator for evaluating the quality of oral solid preparations, and an in vitro evaluation method that simulates the disintegration and dissolution of oral solid preparations in the gastrointestinal tract. The dissolution apparatus provides a mechatronics test equipment controlled by a microcomputer for the dissolution determination method, which is mainly composed of a motor, a constant temperature water bath device, a basket body, a stirring paddle, a dissolution cup and a cup cover, etc. [0003] Due to the large specific heat capaci...
