Pilot Spray Dryer, 10L/h, Manual Control

Principle:

After been filtered and heated the air enters into the air distributor on the top of the dryer. The hot air enters into the drying room in the spiral form and uniformly. Passing through the high-speed centrifugal sprayer on the top of the tower, the material liquid will rotate and be sprayed into the extremely fine mist liquid beads. Through the very short time of contacting the heat air, the materials can be dried into the final products. The final products will be discharged continuously from the bottom of the drying tower and from the cyclones. The waste gas will be discharged from blower.

Application:
The spray dryer is mainly suitable for the production of micro particle powder in laboratories of universities, research institutes and food pharmaceutical and chemical enterprises, and has wide applicability for all solutions, such as emulsion and suspension. It is suitable for drying of heat sensitive substances such as biological products, biological drugs, enzyme preparations, etc. because the ejected materials are only heated in the case of spray into fog sized particles, so they are heated in a moment, which can keep the active components of these active materials from being damaged after drying.

Main Features:
1. Spray dryer uses large color touch screen operation, with memory function.
2. Automatic control: one button start, set the spray process parameters, the temperature reaches the predetermined temperature, the peristaltic pump starts, the touch screen displays animation, and the running process is clearly displayed.
3. Manual control: if the process parameters need to be adjusted in the experimental process, it can be adjusted manually, and the whole experimental process can be dynamically displayed on the color touch screen (animation).
4. Shutdown protection function: when shutdown, just press the stop key, and the machine will stop running immediately except the fan, so as to ensure that the heating part of the equipment will not burn out due to misoperation (forced shutdown of the fan).
5. Spray, drying and collection system is made of high quality 304 stainless steel. The spray drying process is carried out in a pollution-free and stable environment. It provides convenience for researchers to control the experimental process and experimental results, and can solve problems in time. All stainless steel components are easy to disassemble and clean.
6. Built in oil-free air compressor, the particle size of powder is normally distributed, the fluidity is very good, and the noise is very low, less than 60dB, which meets the laboratory noise standard (centrifugal atomization can be selected).
7. In order to meet the user's requirements of adjusting various parameters in the experimental range, the real-time PID constant temperature control technology is adopted in the design of drying temperature control, so that the temperature control of the whole temperature zone is accurate and the heating temperature control accuracy is ± 1 ℃.
8. In order to keep the sample pure, the air inlet filter is equipped.
9. The feeding quantity can be adjusted by feeding peristaltic pump, and the magnetic stirrer can be selected.
10. The particle size of the dried powder is uniform, and more than 95% of the dry powder is in the same particle size range.
