Air supply system

• Fan is the internal mechanical structure of the rotor
• The air supply system of the instrument adopts frequency conversion control to realize the stepless adjustment of the air volume, so as to meet the requirements of different process spray drying experiments.

Peristaltic pump

Peristaltic pump can be adjusted for pipes with different inner diameters and outer diameters. The diameter of the pipe is different, absolute flow is different. This relationship of the standard 19# silicone hose is shown in the diagram.

Features

• SPD-18A Mini spray dryer can obtain a good powder particle sample quickly and directly, and the particles are naturally spherical. It has the following remarkable performance characteristics：
• The instrument is exquisite and small, and the cabinet adopts humanized aesthetic design, and uses special spray painting technology to make the appearance of instrument more high-end;
• Heating pipes and auxiliary machinery parts are made of high strength stainless steel, high corrosion resistance and durability;
• High precision imported double fluid nozzle ensures accurate atomization performance;
• Loading and unloading is simple and fast, the operation is simple and efficient, and the whole spray drying process is carried out in the glassware, which is convenient for the operator to observe the whole experiment process;
• The control system of this equipment is based on the SIEMENS PLC and MHI touch screen. It is designed with the principle of energy saving and high efficiency making the temperature rise more quickly and stably. The temperature control accuracy is within 1°C;
• With a user-friendly window for human computer interaction, customers can fully grasp the important elements such as air flow, inlet temperature and can observe the working state of the instrument in real time, So that customers will have more actual verification space in the spray drying experiment;
• Intelligent remote host computer operation monitoring system makes the user easily complete the spray drying work in the office before the computer.

Applicability of SPD-18A mini spray dryer

• SPD-18A small spray drying apparatus can be used for drying aqueous solution and suspension. It is suitable for the experiment and production of uniform powder. Such as: pharmaceuticals, dyes, pigments, food and beverage, milk, egg products plants and vegetable products, heat sensitive materials, plastics, polymers, resins, ceramics, perfume, soap, detergent, blood, adhesives, oxides, textiles, bone, teeth etc.
• SPD-18A is particularly applicable to the laboratory for liquid material directly into micro powder, without materials filtration, concentrating and crushing before drying, applicable for all solutions such as emulsion, suspension.

Cannot be used to deal with flammable, explosive or easy to produce large amounts of gas material. In particular, gases that are chemically unknown cannot be released.
