AI Technical Summary
Existing pharmaceutical intermediate reaction equipment has poor stirring performance, especially in the corners and edges of the reaction vessel, which are difficult to cover, resulting in incomplete reaction of the medicinal materials.
Spiral blades are used to stir and transport the medicinal materials, which are then returned to the interior of the guide block through a reflux trough. Combined with the inclined guide block and stirring rod, the medicinal materials are stirred and evenly distributed multiple times. Heating wires are used to heat the medicinal materials evenly.
The improved stirring effect of the medicinal materials allows them to react fully, ensuring uniform mixing and heating within the reactor and solving the problem of uneven stirring.
