Method for improving multilayer dropping pill structure and device using in method

Abstract

The invention relates to a method for improving a multilayer dropping pill structure and a device using in the method. On one aspect, the invention relates to a dropping head for preparing the multilayer dropping pill. The dropping head is a detachable and assemble combined structure and comprises an inner material lead-in part, an intermediate material lead-in part, an outer material lead-in part and a connecting part, wherein the upper part of the dropping head is connected with a vibrating apparatus, and the vibrating apparatus enables the dropping head to vibrate up and down in a reciprocating manner. The invention also relates to a multilayer dropping pill device, a method for preparing the multilayer dropping pill and a vibrating apparatus for preparing the multilayer dropping pill. By virtue of the method, the multilayer dropping pill with an excellent and homogenous structure can be prepared.

Description

technical field [0001] The present invention relates to the field of machinery and equipment, in particular to the field of pharmaceutical machinery and equipment, more particularly to a device for preparing multi-layer drop pills and its key components, and more particularly to a device capable of preparing two-layer or three-layer drop pills The equipment and key components thereof, and the two or three layers of the two-layer or three-layer drop pill can be materials with different characteristics, and these multi-layer drop pills have an excellent and uniform structure. Background technique [0002] Dropping pills are a high-end dosage form in the field of pharmacy, which can endow the medicine with special properties due to its special structure. [0003] Dropping pills are small pill-shaped preparations made of solid or liquid medicines and appropriate substances (generally called substrates) after heating, melting and mixing, dropping into immiscible condensate, shrin...

AI Technical Summary

Problems solved by technology

In this state, if the thickness distribution of each layer is uneven during dropping, it will cause the phenomenon that the multi-layer dropping pills are not concentric. For example, for double-layer dropping pills, if the outer layer is spherical with very good roundness, but the inner layer It is an ellipsoid with poor roundness, or even if the inner ball is very round, but it is not distributed in the center of the outer layer, this will cause the centers of each layer of the entire dripping pill to be not at the same point, that is, the concentricity is not good , uneven pellets
