Method for redissolution of plant empty capsule tailings

Abstract

The invention relates to the technical field of plant empty capsule production processes, in particular to a method for redissolution of plant empty capsule tailings, The method comprises a step 1) of evenly mixing purified water and the plant empty capsule tailings at 90-95 DEG C, and obtaining a mixed feed liquid; a step 2) of cooling the mixed feed liquid to 35-40 DEG C, and stirring the mixed feed liquid to make a material dissolved completely to be uniform glue solution; and a step 3) of adjusting the temperature of the glue solution to 40-45 DEG C for standby application. The redissolution method is suitable for the tailings of a plant empty capsule with hydroxypropyl methylcellulose as a main ingredient, and it is measured that the viscosity ranges from 1500-2800 mPa.s when the redissolution glue solution is 43 DEG C. According to the method, the raw material utilization rate can be greatly improved, performances of a recycled and prepared capsule are not reduced, and the method is a method for redissolution of plant empty capsule tailings worth popularizing.

Description

technical field [0001] The invention relates to the technical field of plant hollow capsule production technology, in particular to a method for back-dissolving the tailings of plant hollow capsules. Background technique [0002] my country has 300 billion empty capsules / year output and consumption, but whether these "300 billion empty capsules" can guarantee the safety and effectiveness of drugs has always been the focus and anxiety of the relevant departments of the national drug safety supervision. Domestic medicinal gelatin derived from animal skin and bone has its own shortcomings. The pathogenic factors (such as mad cow disease factor) are not easy to kill, and the detection accuracy is low. This is an international common problem, which is difficult to overcome as long as it is used.

AI Technical Summary

Problems solved by technology

Domestic medicinal gelatin derived from animal skin and bone has its own shortcomings. The pathogenic factors (such as mad cow disease factor) are not easy to kill, and the detection accuracy is low. This is a common problem in the world, and it is difficult to overcome as long as it is used.

Second, after animal gelatin is affected by changes in environmental conditions (light, heat, time) and some ingredients of the drug, it will have negative effects such as reduced curative effect.

The third is that it is difficult to cure the shocking heavy metals caused by man-made pollution, and the investigation and punishment are often after the incident.

[0004] However, it is difficult to realize the industrialization of existing plant-based hollow capsules. The key factor is that the production of plant-based hollow capsules is all dipped in glue. During the cutting process, at least 30% of tailings will inevitably be produced, and the tailings are currently The technology cannot be dissolved and reused, resulting in a reduction of at least 30% in the yield of raw materials per unit, resulting in high production costs, and the inability to scale production and popularize the market
