The structural characteristics and functions of centrifugal granulation coating machine
Date: 2025-12-12Read: 8
Centrifugal granulation and coating machine is a widely used equipment in the pharmaceutical, chemical, food and other industries, used for granulation and coating treatment of granular materials. Through the action of centrifugal force, this device can achieve uniform and efficient particle granulation and coating, and is widely used in the preparation process of particles, such as drug particles, fertilizer particles, chemical particles, etc. It has the characteristics of compact structure, easy operation, and high production efficiency, which can meet the high requirements of modern industrial production. Its main applications include drug coating and granulation, fertilizer granulation, and preparation of food additive granules.
Centrifugal granulation coating machineStructural characteristics:
1. Granulation disk or coating disk: As the core component, the granulation disk or coating disk is the source of centrifugal force, usually made of stainless steel material, with a smooth surface, easy to clean and maintain. The shape, inclination angle, and rotation speed of the disc directly affect the granulation effect of the particles.
2. Spray system: The spray system is used to evenly spray coating liquids, adhesives, and other substances onto the surface of particles. Generally, the nozzle is designed to be adjustable, and the spray amount can be adjusted according to the particle size and production demand.
3. Airflow system: Airflow system is used to control the flow of air, regulate the temperature and humidity of the airflow, and help dry the particles and solidify the coating layer. Airflow systems typically include components such as fans, ducts, heaters, etc.
4. Transmission system: The granulation disc or coating disc is driven to rotate by an electric motor. The transmission system usually includes a motor, reducer, belt, gear, etc.
5. Control system: Usually equipped with a PLC control system, it can automatically adjust various parameters such as rotation speed, spraying amount, airflow temperature, etc., ensuring the stability and efficiency of the entire process.
6. Collection and screening system: The collection system is used to collect formed particles, while the screening system is used to grade particles to ensure that their size and quality meet the requirements.
Application areas of centrifugal granulation coating machine:
1. Pharmaceutical industry:
The application in the pharmaceutical industry is mainly reflected in the granulation and coating process of drug particles. Through this device, uniform drug particles can be produced and coated to improve drug stability, prolong release time, or enhance taste. For example, coated drugs can prevent rapid release of drugs in the stomach, thereby achieving sustained or controlled release effects.
2. Fertilizer industry:
It plays an important role in fertilizer production, mainly used for granulation and coating of fertilizer granules. Through coating technology, the stability of fertilizers can be improved, waste can be reduced, and their effectiveness can be extended. For example, in the production process of slow-release fertilizers, coating technology can be used to control the release rate of fertilizers and reduce environmental pollution.
3. Food industry:
In the food industry, it is used for granulation and coating of particles such as food additives, spices, seasonings, etc. By coating treatment, the stability, solubility, and taste of these substances can be improved. For example, granulation coating machines can be seen in applications such as candy coating and spice coating.
4. Cosmetics industry:
It can also be used for granulation and coating of cosmetic raw material particles, especially in the production of powdered and granular cosmetics. Coating technology can increase product stability and improve its effectiveness.
