A New Technology for Drying Soft Capsules

Abstract

The invention discloses a new technology for drying soft capsules, which is composed of soft capsules shaping, drying in a tumbler and tray drying. For air control, the air supply in the drying room adopts a horizontal circulation air supply system. By adjusting the temperature and humidity in the drying room, the practical problems such as capsule adhesion and cracking of soft capsules under the traditional drying technology can be effectively solved, so that the freshly pressed soft capsules can be dried stably, and the quality of the product is also reduced. drying costs.

Description

Technical field: [0001] The invention relates to a new technology for drying soft capsules, which is designed for the pharmaceutical industry and belongs to the field of drying soft capsule medicines. Background technique: [0002] Soft capsules were invented by French pharmacist Mothes in 1883. After embedding oily medicines in capsules, they can be taken as a solid medicine more conveniently. Bad smell, beautiful appearance, easy to carry and use, etc. Among oral drugs in different dosage forms, the bioavailability is best in soft capsules containing solution-like contents. [0003] The soft capsules are prepared by pressing method or dripping method, and the soft capsules all need to be dried after molding. The water contained in the soft capsule wall has a certain influence on the disintegration time of the medicament. Since the main component of the soft capsule shell is gelatin, it consists of more than 85% protein, about 2% minerals and about 13% water and contains ...

AI Technical Summary

Problems solved by technology

Since the crawler drying system cannot dehumidify alone; it has a humidification effect on other air-conditioning systems and destroys the temperature and humidity control balance of other systems

[0006] 2. The drying efficiency is low, the time is long, the labor intensity of the workers is high, and the working environment is harsh. Since the relative humidity in the drying area cannot be lowered, the time span of the drying process is too long, and the entire process from low temperature setting to medium temperature drying room Time ≥ 56 hours, because the temperature in the drying room is too high

The moisture is not exhausted enough, so the requirements for manual turning of the meatballs are very high, and people are prone to fatigue, heatstroke and other phenomena when continuously operating the meatballs at a high temperature above 40°C

[0007] 3. The drying air supply is uneven, which leads to rework of the process. Due to the design defect of the crawler conveying form, the air duct is single, resulting in uneven contact surface between the capsule and the wind direction. When the conveying time is long, it is prone to deflection, resulting in uneven drying of the product. uniform

[0008] 4. The flow of the process equipment scheme is cumbersome. The yield of the drying process is low. After the product dripping process is completed, there will be 3-4 times of soft capsule product movement.

Often leads to breakage of semi-finished products

Secondly, due to the error of the moving position of the conveyor belt, a large number of soft capsule products are damaged due to extrusion

Broken products will in turn contaminate the conveyor belt and other good products

This in turn results in a large amount of shot

In addition, due to the uneven air supply of the crawler drying equipment, when some products that have not been dried are directly sent to the final drying room for drying, they will be cracked or double-grained due to being too soft, which again reduces the yield of the drying process.
