In an aseptic spray drying system, all materials and air entering the system must be sterilized. The collection of the product must also be carried out in a sterile room. For this purpose, the liquid to be sprayed must be filtered and sterilized before it can be sent to the sprayer. The compressed air used for spraying must also be purified before it can be used. (The above two users take care of themselves)
The air used for drying is passed through the primary and middle efficiency filters, and the high-purity filter is used to filter the purified air. The temperature is then increased by the heater to the spray dryer. The dried product is separated from the air by a cyclone separator. The finished product is collected on the clean room clean bench. The tail gas is drained after net filtering by the bag filter.
Product features: The device adopts two-flow air atomizer, simple structure, good air flow, uniform atomization, and can meet the requirements of aseptic spray.
There is a sweeping device inside the spray tower to facilitate the cleaning of the wall of the tower.
The hot air purification adopts the three-stage filter system of early effect, intermediate effect and high efficiency, so the air purification quality is high and it meets the requirements of GMP pharmaceutical production.
Changzhou One-Step Drying Introduces Sterile Spray Dryer
Aseptic spray drying device is the main equipment for powder injection production in the pharmaceutical industry. Many antibiotic drugs such as streptomycin sulfate, gentamicin sulfate, and kanamycin sulfate are used in the production process. Bacteria spray drying to prepare the finished product. The recently introduced sterile spray dryer in Changzhou is a two-flow air sprayer with one-step drying. The structure is simple, the air flow is well contacted, and the atomization is uniform, which can meet the requirements of aseptic spray.
