What are the airflow spray dryers used in the pharmaceutical industry?

The airflow spray dryer is a kind of drying equipment commonly used in the pharmaceutical industry. Its main feature is to atomize the product liquid into tiny particles through the sprayer, and quickly dry it into powder under the action of hot air, so as to achieve the effect of drying and preparing products. The following are several types of airflow spray dryers commonly used in the pharmaceutical industry:

1. Ordinary airflow spray dryer: Ordinary airflow spray dryer is a basic model of airflow spray dryer. Its main feature is to quickly dry the sprayed products into powder under the action of hot air, which can be used to prepare various powder products.

2. Airflow spray dryer with recovery system: The airflow spray dryer with recovery system is a kind of equipment integrating drying and recovery, which can recover and separate the dried products and undried gas through the recovery system, thereby improving Improve the utilization rate and economic benefits of the equipment.

3. Vacuum airflow spray dryer: Vacuum airflow spray dryer is a kind of equipment for spray drying in a vacuum environment. It can be used to prepare some products that are easy to oxidize, easy to decompose, and easy to deteriorate, and the drying effect is better.

4. Spray drying-fluidized bed drying integrated machine: Spray drying-fluidized bed drying integrated machine is a kind of equipment that combines airflow spray drying and fluidized bed drying, which can be used to prepare various powder products, and can also realize A series of process operations such as product drying, crushing and screening have high efficiency.

In short, the airflow spray dryer is a commonly used drying equipment in the pharmaceutical industry. It has a wide variety, and different types of equipment can be selected according to different production needs.
