1、 Core technical characteristics of spray dryer for Chinese herbal extracts
1. Efficient centrifugal atomization technology
Using a high-speed centrifugal atomizer, the paste is dispersed into micrometer sized droplets, which are instantly dried by contact with hot air. The water evaporation rate can reach 5-10kg/h. This technology can shorten the drying time by 40%, and the retention rate of thermosensitive components can reach up to 98%.
2. Anti stick wall and coking control
By using air wall sweeping devices and tower wall jacket cooling structures, the problem of traditional equipment sticking to the wall is effectively solved, maintaining the wall temperature below 80 ℃ and increasing the powder collection rate to over 95%. Some models are also equipped with air brush tower sweeping devices to further reduce material residue.
3. Intelligent temperature control and cleaning system
The inlet temperature can be precisely controlled within the range of ± 2 ℃ (160-220 ℃), and the exhaust temperature can be adjusted to 80-100 ℃. The equipment adopts a three-level air purification system to ensure that the incoming air meets the 300000 level cleanliness standard and complies with GMP regulations.
2、 Structure and Material Design of spray Dryer for Chinese Herbal Extract
Fully enclosed stainless steel structure: All parts in contact with the material are made of SUS316 stainless steel, with a polished inner wall roughness of ≤ 0.4 μ m to avoid cleaning dead corners.
• Modularization and customization: A/B/C configurations are provided based on material characteristics, supporting laboratory to pilot production scenarios, with a 30% increase in drying efficiency compared to traditional equipment.
Energy saving and environmental protection: The jacket cooling air is recycled to the new air outlet to reduce energy consumption; The exhaust gas is treated with cyclone dust removal and wet dust removal, and the dust emission is ≤ 120mg/m ³.
