Product information
Streptomycin centrifugal spray dryer
working principle
Streptomycin centrifugal spray dryer The air passes through the filter and heater and enters the air distributor at the top of the centrifugal spray dryer. The hot air enters the dryer evenly in a spiral shape. The feed liquid is pumped from the feed liquid tank through the filter to the centrifugal atomizer at the top of the dryer, so that the feed liquid is sprayed into extremely small mist droplets. The feed liquid and hot air come into parallel flow contact, and the water quickly evaporates. In a very short time, it is dried into a finished product. The finished product is discharged from the bottom of the drying tower and the cyclone separator, and the exhaust gas is discharged from the fan. Users can select heating methods and dust collection and dust removal methods according to actual conditions.
product features
1. Large color touch screen operation, combination of full automatic control and manual control, Chinese and English panels, parameter LCD display
2. Real-time control of PID constant temperature control technology, accurate temperature control, heating temperature control accuracy ±1℃
3. The spraying, drying and collection device is made of transparent, high-quality, high-temperature resistant, high-borosilicate glass. The entire spray drying experimental process is visible, which is easy to control the experimental process and can detect and adjust problems in a timely manner.
4. The atomization structure of the two-fluid spray is made of high-precision 316 stainless steel. The particle diameter of the spray powder is normally distributed and has good fluidity.
5. The jet is automatically unblocked (through the needle) and the frequency is adjustable. When the nozzle is blocked, it will automatically clear to ensure the continuity of the experiment.
6. The feed amount can be adjusted by a feed peristaltic pump, with a minimum sample experimental volume of 30ml
7. It has a protective function. The fan cannot be started and the heater cannot be started.
8. Built-in imported oil-free air compressor with noise less than 50db
9. Equipped with an air inlet filter to ensure purity of the sample
10. The dried product has uniform granularity, and more than 95% of the dry powder is in the same granularity range
11. Optional spray head water cooling device to meet the needs of heat-sensitive material drying process
12. Optional nitrogen circulation access system to achieve organic solvent drying process
13. Comply with EU CE quality certification and operate safely and stably
application range
It is suitable for the production of micro-particulate powders in universities, research institutes and laboratories of food, pharmaceutical and chemical enterprises. It has wide applicability to all solutions such as emulsions and suspensions. It is suitable for the drying of heat-sensitive substances such as biological products, biopesticides, enzyme preparations, etc. Because the sprayed materials are only exposed to high temperatures and are heated instantaneously when sprayed into a mist, these active materials still maintain their active ingredients unchanged after drying.
Specifically used in the following fields: beverages, spices and coloring, milk and egg products, plant and vegetable extracts, pharmaceuticals, synthetic heat-sensitive substances, plastics, polymers and resins, fragrances, blood products, ceramics and superconductors, biochemical products, dyes, soaps and detergents, food adhesives, oxides, bone meal and tooth powder, etc.

Note: Water evaporation is related to the characteristics of the material and the hot inlet air and outlet temperatures. When the outlet temperature is 90C, the water evaporation curve is shown in the figure above (for selection reference). As the product continues to be updated, relevant parameters are subject to change without prior notice.
