Stirring and mixing device for preparing starch-based rubber skin

Abstract

The invention discloses a stirring and mixing device for preparing a starch-based rubber skin and belongs to the field of capsule production equipment. The stirring and mixing device comprises a box body (9), a cover plate, a stirring shaft (11) and a driving motor (12), wherein the stirring shaft is provided with stirring teeth with the quantity being not less than four pairs; the stirring teeth are arranged on the stirring shaft from top to bottom at equal distances; the teeth lengths among the adjacent stirring teeth are increased by an equal value being 5-20cm, and the two adjacent pairs of stirring teeth are arranged on the stirring shaft in a cross shape; the bottom of the box body is provided with a main discharging pipe (8) which is provided with a main valve (8.1); the main discharging pipe between the main valve and the box body is also provided with an auxiliary discharging pipe (7) which is provided with an auxiliary valve (7.1), and the hole diameter of the auxiliary discharging pipe is 5-10cm. The stirring and mixing device disclosed by the invention has the advantages that selected materials are fully stirred, so that the flocculation caused by local viscosity is avoided; by full stirring, the mixing of starch and ingredients is uniform, so that the stable performance of the prepared rubber skin is ensured and the use requirement is met.

Description

technical field [0001] The invention relates to a stirring device, in particular to a stirring and mixing device for preparing starch-based rubber, and belongs to the field of capsule production equipment. Background technique [0002] As a new dosage form, soft capsules are injected quantitatively into oily substances, solutions or suspensions, pastes or even powders and encapsulated in the film to form sealed capsules of various sizes and shapes. High efficacy, high curative effect, etc., are greatly favored by the market. The rubber is the capsule wall of the soft capsule, and the liquid medicine is wrapped in the rubber to form a capsule with greater elasticity, which is convenient for patients to take orally. The traditional rubber is mostly made of gelatin. Since the gelatin easily contains animal protein residues, it may interact with the drug and affect the efficacy of the drug. Therefore, people are gradually using vegetable capsules to replace gelatin. [0003] S...

AI Technical Summary

Problems solved by technology

At present, when preparing starch capsules, it is necessary to mix and stir the starch and other ingredients first, and then carry out follow-up operations such as glue making, pelletizing, and drying after the mixing is completed. Due to the high viscosity and poor water solubility of starch itself, traditional mixing equipment is When stirring, starch flocculation often occurs at the bottom of the equipment, resulting in uneven mixing of the upper and lower parts of the starch, resulting in poor performance of the prepared rubber
