Product details
[Product Description]
WPG-220 mini laboratory spray dryer is a self-developed and designed by Shandong Ono for the scientific research department of universities, research institutes and enterprises, which is engaged in small-scale and pilot research in the process of new product research and development. The processing capacity of feed liquid is only 100~1000ml/h, which is suitable for direct spray drying of some liquid materials in the stage of small-scale test. The liquid materials before drying are required to have good fluidity, filter clearly, be able to achieve pumping and atomization, and obtain fine powder products after drying. This machine is an experimental equipment, which is used to test whether the tested materials are suitable for spray drying, explore the influence of thermal parameters on the drying effect during the drying process, and provide samples for physical analysis of spray dried products.
At present, there are over a hundred domestic users and the product has been successfully sold to Europe, the Middle East, and Southeast Asia, breaking the monopoly of developed countries such as Europe and Japan in this field in China.
WPG220 is the second generation micro laboratory spray dryer developed by Ono, which has been comprehensively improved on the basis of the first generation of WPG120. Compared with similar products in Europe and Japan
1. The diameter of the drying chamber has been expanded from the original Φ 120mm to Φ 220mm, making it less prone to wall sticking and providing more stable and reliable performance.
2. The whole machine is more compact, small in size, and easy to move.
3. Beautiful appearance, precise control, easy disassembly and installation.
【 Working Principle 】
The liquid in the liquid cup is transported to the two fluid air flow nozzle at the top of the drying chamber through a peristaltic pump. In the drying chamber, it is atomized into small droplets by compressed air generated by an air compressor, and fully contacts with the hot air heated by an electric heater for heat and mass transfer, completing the drying process. Most of the moisture in the liquid is evaporated, and some of the dried products settle into the powder cup at the bottom of the drying chamber. The exhaust gas discharged from the drying chamber is separated into gas-solid in the cyclone separator, and the product is collected and collected in the powder cup. The exhaust gas is discharged into the atmosphere through a induced draft fan. Through the electrical control system, parameters such as inlet air temperature, exhaust air temperature, liquid feed rate, compressed air flow rate, and induced draft fan air volume can be adjusted according to different product performance requirements.
【 Main Features 】
a. The maximum spray volume is only 1000ml/h, which provides an ideal spray drying method for the small test in the process of new product research and development in the fields of traditional Chinese medicine, biological products, fine chemicals, new materials, chemicals, etc.
b. The main body and supporting equipment of the dryer are miniaturized, lightweight, small in size, compact in structure, adjustable in all parameters, and easy to operate.
c. The drying chamber, cyclone separator, and material drum are connected by quick couplings, making disassembly and cleaning quick and convenient.
d. The material of the drying chamber, cyclone separator, and material cylinder is colorless and transparent borosilicate glass that meets pharmaceutical grade hygiene standards. The drying effect is intuitive and easy to observe and control during the testing process.
e. Compared with the first generation micro laboratory spray dryer, the diameter of the drying chamber is large, the possibility of wall sticking is reduced, and the use performance is more stable and reliable.
f. The platform adopts a movable structure, and the entire frame is sprayed with plastic, which is beautiful, durable, and easy to move.
g. The atomizer, as the core component, adopts imported products with reliable performance; Glass components, material pumps, fans, electrical controls and other accessories have all been localized, with low maintenance costs and timely after-sales service.
