The centrifugal spray dryer is applicable to the production of micro particle powder in universities, research institutes and laboratories of food, medicine and chemical enterprises. It is widely applicable to all solutions such as emulsion and suspension, and is applicable to the drying of heat sensitive substances such as biological products, biological pesticides, enzymes, etc. Due to the fact that the sprayed material only experiences high temperature and instant heating when sprayed into a mist, these active materials maintain their active ingredients unchanged even after drying. Specifically used in the following fields: beverages, spices and pigments, milk and egg products, plant and vegetable extracts, pharmaceuticals, synthetic thermosensitive substances, plastics, polymers and resins, aromatic agents, blood products, ceramics and superconductors, biochemical products, dyes, soaps and detergents, food adhesives, oxides, bone powder and tooth powder, etc.
The working principle of the centrifugal spray dryer is that the air enters the air distributor on the top of the centrifugal spray dryer through the filter and heater, and the hot air enters the dryer evenly in a spiral shape. The material liquid is pumped from the material liquid tank to the centrifugal atomizer at the top of the dryer through a filter, causing the material liquid to spray into extremely small mist droplets. The material liquid and hot air come into contact in parallel, and the moisture evaporates rapidly, drying into finished products in a very short time. The finished products are discharged from the bottom of the drying tower and the cyclone separator, and the exhaust gas is discharged by the fan. Users can choose the heating method, dust collection method, and dust removal method according to their actual situation.
Main advantages of centrifugal spray dryer:
1. The spray, drying and collecting device is made of transparent, high-quality, high temperature resistant high borosilicate glass. The whole process of spray drying experiment is visible, which is convenient to control the experiment process and find and adjust problems in time.
2. The atomization structure of two fluid spray is made of high-precision 316 stainless steel. The particle size of the powder sprayed is normally distributed, and the fluidity is good.
3. Real time PID constant temperature control technology, accurate temperature control, heating temperature control accuracy ± 1 ℃.
4. There is a protective function, but the fan cannot start and the heater cannot start.
5. The jet nozzle automatically clears (passes through the needle) and has an adjustable frequency. When the nozzle is blocked, it will automatically clear to ensure the continuity of the experiment.
6. The feeding amount can be adjusted by the feeding peristaltic pump, with a minimum sample experimental volume of 30ml.
7. Compliant with EU CE quality certification, safe and stable operation.
8. Built in imported oil-free air compressor with a noise level of less than 50db.
9. Color large touch screen operation, combination of fully automatic control and manual control, Chinese and English panel, parameter LCD display.
10. The dried product has uniform particle size, with over 95% of the dry powder within the same particle size range.
11. Equipped with an air inlet filter to ensure sample purity.
12. The nitrogen circulation access system is optional to achieve organic solvent drying process.
13. The spray head water cooling device is optional to meet the drying process needs of heat sensitive materials.
