Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical devices, in particular to a reaction kettle for medicine preparation. Background Art

[0002] The broad understanding of the reactor is a stainless steel container for physical or chemical reactions. The structural design and parameter configuration of the container are carried out according to different process conditions. The design conditions, process, inspection, manufacturing and acceptance must be based on relevant technical standards to achieve the heating, evaporation, cooling and low-speed mixing reaction functions required by the process.

[0003] Existing high-efficiency reactors for biopharmaceutical preparation have the following defects: when stirring the materials, a stirring device is used to stir the materials in the reactor, and there are dead corners in the stirring, and the stirring is uneven and insufficient; the heating device is usually arranged on the outer wall, so that the center position of the reactor cannot be heated, and the heating is uneven; because the internal stirring device is connected to the external motor, the sealing is poor; the reaction rate is low and the use effect is not good.

[0004] The existing patent (Announcement No.: CN208944114U) discloses that the materials are stirred by rotating the kettle body instead of the traditional stirring device, so that there is no dead angle in the stirring, the stirring is more sufficient, the materials are mixed more evenly, and the reaction rate of the materials is improved. The materials are fully stirred and mixed by the first spiral blade and the second spiral blade, so that the reaction is more sufficient, the reaction rate is further improved, and the reacted materials are sent to the discharge port, which is convenient for the staff to collect the materials. The kettle body is heated 360° in all directions by the MT-2 digital display constant temperature electric sand bath, which greatly improves the reaction rate of the materials.

Secondly, the equipment is heavy and has a stable structure, which is not conducive to discharging.
