A multifunctional raw material dryer

Abstract

The invention discloses a multifunctional raw material drier which comprises a vertical cylindrical drying barrel. The top face of the drying barrel is of a conical shape, the top end of the drying barrel is connected with an exhaust pipe, the bottom face of the drying barrel is of an inverted-circular-cone shape, and the bottom end of the drying barrel is connected with a discharging pipe; the side wall of the drying barrel is internally provided with a heating device, the top face of the drying barrel is provided with two feeding openings, and the two feeding openings are fixedly provided with a high-pressure spray head and an atomizing spray head correspondingly; the high-pressure spray head and the atomizing spray head are connected with a high-pressure pump through guide pipes, and an electromagnetic valve is arranged between the high-pressure pump and the high-pressure spray head and is also arranged between the high-pressure pump and the atomizing spray head; and the high-pressure pump is connected with a material storage device, the side wall of the drying barrel is provided with a round hole, the round hole is internally provided with a rotating shaft, the positions, located on the two sides of the interior of the drying barrel, of the rotating shaft are each provided with a semicircular filtering mesh, the diameter of the semicircular filtering mesh is slightly smaller than the inner diameter of the drying barrel, and the end, located on the outer side of the drying barrel, of the rotating shaft is connected with a stepping motor. By means of the drier, medicine can be dried continuously, drying efficiency is high, drying is efficient, and the application range is wide.

Description

technical field [0001] The invention relates to the field of medicine production equipment, in particular to a multifunctional raw material dryer. Background technique [0002] In the preparation process of raw materials or pharmaceutical intermediates, it is usually necessary to dry the prepared drugs and store them. The existing drug drying devices usually need to place the drugs in the drying equipment for drying. After the drying is completed, the The finished product is taken out, and then the next batch of medicine to be dried is placed in the drying equipment for drying, and the drying efficiency of the medicine is low. The existing drying equipment has a single function. During the drying process of medicines, it is difficult for the existing drying equipment to fully dry some non-bonding powdery, crystalline and amorphous materials, resulting in adverse effects of incompletely dried materials on the rest of the materials. , reducing the quality of pharmaceutical pr...
