　　Experimental spray dryer

　　Experimental spray dryer(Equipment) is produced domestically by our company through the introduction and absorption of international technology; Import of main components and electrical appliances. The whole machine is compact in design, movable, and self-contained, and can be used without the need for auxiliary facilities to be powered on. Adopting PLC control, touch screen display, and Chinese English operation interface.

　　Experimental spray dryerIt is mainly suitable for the research and production of trace particle powders in universities, research institutes, and laboratories of food, biology, beverage, chemical, materials, pharmaceutical and other enterprises. It has broad-spectrum applicability to all solutions such as emulsions and suspensions, and is suitable for drying thermosensitive substances such as biological products, biopesticides, enzyme preparations, etc. Because the sprayed material is only subjected to high temperature when sprayed into mist like particles, it is only instantly heated and can maintain the active ingredients of these active materials without damage after drying.

Application fields of HZ-1500 spray dryer: beverages, spices and pigments, milk and egg products, plant and vegetable extracts, pharmaceutical synthesis, thermosensitive plastics, polymers and resins, aromatics, blood products, ceramics and superconductors, biochemical products, dyes, chemical materials, soaps and detergents, food adhesives, oxides, bone powder and tooth powder, etc.

　　Characteristics of spray dryer:

1. The spray, drying chamber and collection device are made of transparent, high-quality, high temperature resistant and high borosilicate glass (tempered glass), so that the spray drying process can be carried out in a pollution-free and stable environment. The whole process of spray drying experiment can be seen, which is convenient for controlling the experiment process and finding and adjusting problems in time. All glass components are easy to disassemble and clean.

2. The built-in oil-free air compressor has a normal distribution of particle size for powder spraying, good fluidity, and very low noise, less than 60dp, which meets the national laboratory noise standards.

3. The atomization structure of the two fluid spray is made of high-quality and high-precision 316 stainless steel material, with uniform atomization.

4. The temperature control adopts real-time PID constant temperature control technology, ensuring accurate temperature control.

5. The feeding amount can be adjusted by a peristaltic pump, and a minimum of 30ml of sample can also complete one experiment.

6. The jet nozzle automatically clears (passes through the needle) and the frequency can be adjusted. When the nozzle is blocked, it will automatically clear to ensure the continuity of the experiment.

7. Fully automatic manual dual mode, PLC control, color touch screen display, Chinese and English operation interface, all parameters have LCD display.

8. It has a protective function. If the fan does not start, the heater cannot start.

9. The dried finished dry powder has a relatively uniform particle size, with over 95% of the dry powder within the same particle size range.

10. It can be used immediately after being powered on, without the need for any auxiliary facilities.

　　Two fluid nozzle：

The stainless steel nozzle includes an inner tube for conveying liquid material. And an injector with precise internal tolerance, the outer tube provides compressed air to the nozzle. The precision manufacturing between the injector and nozzle ensures that the liquid jet is well vaporized into a mist, and the HZ-1500 standard is equipped with a 0.75 injector. There are other aperture injectors available as accessories. The injector has an automatic unblocking needle device, and the spring needle rod can be controlled to set the frequency. The entire action is executed by the built-in compressor, and the injector automatically unblocks the blockage, preventing material solidification in the injector and large particles from blocking the jet.
