Low temperature spray drying tower equipment 5KG

Low temperature spray drying tower equipment 5KG

1. The main body of the drying tower adopts a double-layer stainless steel structure, with 316L stainless steel on the inner wall, mirror polished Ra ≤ 0.4 on the inner wall, 304 stainless steel on the outer wall, and insulation material filled in the middle. The inner and outer steel plates are ≥ 3mm, and the insulation interlayer is not less than 50mm.

2. The insulation material for equipment insulation needs to be welded and sealed with 304 stainless steel material (on the outer surface of the equipment), without leakage, with a beautiful appearance, and material certification documents should be provided.

1. Equipped with a spray gun air pressure detection device, the spray gun air pressure can be adjusted, and atomization can be controlled. By controlling the pressure/flow rate of the atomized compressed air, different sizes of droplets can be prepared. The air pressure is set, and if it exceeds the set low value, an alarm will be triggered. If the pressure is lower than the set low value, the spray will automatically stop.

2. The spray gun shall spray liquid evenly, without overlapping, without droplets, and the atomization state is stable during the spray process. The spray gun can be disassembled online, with atomization pressure display and easy regulation. It also has a function to prevent dripping. When stopping spraying, the spray gun must not drip or leak air. The spray gun should be an international or domestic brand.

3. Set protection program, compressed air does not enter, and liquid inlet cannot be started.

The bag collector is equipped with anti-static sanitary grade filter bags for fine particle collection. The bag material is PET/PTFE, and material certification is required. The aperture is customized according to the process requirements. The bag brand should be an international or domestic brand.

1. Equipped with explosion-proof fans and motors, all electrical components in the clean area are made of explosion-proof electrical components. The electrical control cabinet is isolated to the auxiliary machine room and equipped with a micro positive pressure operation box. Explosion proof electrical control cabinets are required for weak current electrical control cabinets. The motor brand should be an international or domestic brand.

2. The explosion vent is equipped with explosive discs, and the capture chamber cylinder is equipped with pressure detection; The venting channel is connected to the technical interlayer.

1. The liquid inlet system is equipped with a mobile temporary storage tank for storing liquid medicine. The temporary storage tank should have stirring and heating insulation functions. The surface of the tank should be mirror treated with Ra ≤ 0.4 μ m, and the surface of the tank should be brushed or sandblasted with Ra ≤ 0.8 μ m.

2. The mobile temporary storage tank should be equipped with a liquid level sensor to monitor the liquid level inside the tank, and an online measuring module can be optionally selected for precise measurement.

3. The inlet pump is equipped with a variable speed peristaltic pump (with flow display), diaphragm pump, or clean gear pump, and the material in contact with the material is clean silicone, PTFE, or 316L stainless steel. Connected with the host, using explosion-proof motors and requiring variable frequency control. The inlet pump should be an international or domestic brand.
