A chemical and pharmaceutical granulator

Abstract

The invention discloses a chemical and pharmaceutical granulator, the structure of which comprises a feeding funnel, a crusher, an installation platform, a granulation box, and a granulation outlet. The granulation box and the crusher are connected and matched together through the installation platform. On the crusher, the granulation outlet is set on the granulation box. The interior of the crusher is equipped with a feed inlet, a crushing chamber, a shell, and a discharge outlet. The feed inlet is integrated with the crushing chamber and the discharge outlet, and the three are connected internally. , the outer surface cover of the crushing cavity is provided with a shell, and the crushing cavity is composed of a sealing disc, a high-speed rotating motor, and a crushing mechanism. When not working, the hammer head can be put into the sealing plate for sealed storage, which can avoid the humid air in the crushing cavity from wetting the hammer head, prevent the hammer head from rusting and improve the crushing efficiency.

Description

technical field [0001] The invention relates to the chemical and pharmaceutical field, in particular to a chemical and pharmaceutical granulator. Background technique [0002] In the process of pharmaceutical granulation, it is first necessary to carry out drug crushing to make the drug better granulated. Drug crushing is mainly the operation process of crushing large solid substances into appropriate fineness by means of mechanical force. [0003] The main purposes of crushing are: (1) to increase the surface area of ​​the drug and promote the dissolution of the drug; (2) to facilitate the preparation of various pharmaceutical dosage forms; (3) to accelerate the dissolution of the active ingredients in the medicinal material; (5) It is convenient for drying and storage of fresh medicinal materials. [0004] The difficulty of drug crushing mainly depends on the structure and properties of the substance, but it is also closely related to the size of the external force. Vario...

[0005] The impact crushing method mainly uses the heavy hammer to violently and quickly impact the material to crush it. Due to the different types of materials, their performance is also different. In some relatively humid working environments, the impact surface of the heavy hammer Humidity will not only cause rust, but also increase the adhesion of the drug during crushing, so that the drug cannot be sent out well when the material is cut, resulting in insufficient drug utilization
