A kind of drying equipment for pharmaceutical intermediates

Abstract

The invention discloses a pharmaceutical intermediate drying equipment, which comprises a tank body, a first collecting hopper is embedded in the center of the top wall of the tank body, and a plurality of first discharge holes are evenly distributed on the circumference of the bottom of the first collecting hopper and a plurality of second discharge holes, each of the first discharge holes and the bottom of the second discharge holes are respectively connected with a first material guide pipe; the bottom of the first collecting hopper is sequentially provided with a heating assembly and a second Two collection hoppers; the bottom of the second collection hopper is connected with a diversion mechanism, and a plurality of first umbrella-shaped material guide plates and a plurality of second umbrella-shaped material guide plates are sequentially arranged under the said diversion mechanism. The first umbrella-shaped material guide plates Shaped material guide plates and the second umbrella-shaped material guide plates are arranged alternately; a material guide block is fixed on the bottom wall of the tank body, and the bottom center of the material guide block is connected with a A discharge pipe, one side of the material guide block is connected with an air inlet pipe; the invention has the characteristics of good drying effect and uniform drying of materials.

Description

technical field [0001] The invention relates to the technical field of intermediate processing, in particular to a drying equipment for pharmaceutical intermediates. Background technique [0002] The so-called pharmaceutical intermediates are actually some chemical raw materials or chemical products used in the process of pharmaceutical synthesis. This kind of chemical product does not require a drug production license, and can be produced in an ordinary chemical factory. As long as it reaches a certain level, it can be used in the synthesis of drugs. In the production process of pharmaceutical intermediates, drying it is a must. missing process. [0003] With the existing drying equipment, when drying the intermediate material, due to the small contact area between the intermediate and the drying equipment, and the inconvenience of fully dispersing the material due to the existing equipment, the surfaces of the intermediate material are heated unevenly, which affects the q...

Problems solved by technology

[0003] With the existing drying equipment, when drying the intermediate material, due to the small contact area between the intermediate and the drying equipment, and the inconvenience of fully dispersing the material due to the existing equipment, the surfaces of the intermediate material are heated unevenly, which affects the quality of the intermediate material. The uniformity of drying; at the same time, when the intermediate material is dried, the contact time with the hot air is short, which reduces the drying efficiency
