Laboratory spray dryer

Product Details

Laboratory spray dryer product overview :
The laboratory spray dryer is suitable for the production of micro-particle powder in universities, research institutes and food and pharmaceutical chemical enterprises. It has wide applicability to all solutions such as emulsions and suspensions. It is suitable for drying sensitive substances such as biological substances. Products, biological pesticides, enzyme preparations, etc. Because the materials sprayed by the laboratory spray dryer are only subjected to high temperatures and are instantaneously heated when sprayed into a mist, these active materials maintain their active ingredients after drying.
A variety of areas: beverages, spices and pigments, milk and egg products, plant and vegetable extracts, pharmaceutical synthetic heat sensitive materials plastics, polymers and resins, fragrances, blood products, ceramics and superconducting biochemicals, dye soaps and washing Agents, foods, adhesives, oxides, bone meal and tooth powder, etc.
Main features of the laboratory spray dryer :
Original self-produced nozzle, high efficiency.
Color large touch screen operation, automatic control and manual control, Chinese and English panel, parameter LCD display.
Real-time regulation of PID constant temperature control technology, accurate temperature control, heating temperature control accuracy ± 1 °C.
●The spray, drying and collecting device is made of transparent high-quality high-temperature borosilicate glass , and the whole process of spray drying can be seen.
The atomization structure of the two-fluid spray is made of high-precision 316 stainless steel material. The diameter of the powder spray is normally distributed and the fluidity is good.
●The jet is automatically unblocked (through the needle) and the frequency is adjustable. When the nozzle is blocked, it will be automatically cleared to ensure the continuity of the experiment.
● The feed amount can be adjusted by the feed peristaltic pump.
Special protection function, the fan does not start, the heater can not start.
Built-in imported oil-free air compressor, the noise is less than 50db .
Equipped with air inlet filter to ensure the sample is pure.
●After drying, the granularity is uniform, and more than 95% of the dry powder is in the same granularity.
