summary

Traditional Chinese medicine extract is extracted from plant roots, stems and leaves, especially the alcohol extraction process. It contains high sugar, and is easy to soften and melt under high temperature. Ordinary centrifugal spray can no longer meet the drying requirements. In response to this situation, our company has organized a number of lean technical forces, summarized the successful experience of our factory in designing and manufacturing spray dryers over the years, collected the advantages of the same type of products in the same industry at home and abroad, developed a special spray dryer unit for traditional Chinese medicine through precise, repeated process calculations and countless experiments, and promoted it to some well-known pharmaceutical factories.

  Equipment features

The design of spray drying unit for traditional Chinese medicine has been improved:
1. The tower diameter and height have been adjusted accordingly to ensure that the material does not come into contact with the tower wall before drying, and to ensure the residence time of the material in the hot air; The tower wall is equipped with a jacket cold air cooling device to ensure that the material is adsorbed on the tower wall and may soften, melt, or even coke due to local high temperatures; The cone angle increases, and an air shock absorber is installed on the cone. The compressed air pulse seismic cylinder is used to smoothly shoot down the powder adsorbed on the cylinder;
2. All parts of the host that come into contact with materials use flat or curved transitions, and the contact surfaces are polished and polished (precision polishing to 10 or more) to avoid sand holes and blind spots. Eliminate material accumulation and blockage; The entire unit and material contact area are made of stainless steel to ensure that the materials are not contaminated; The transmission components in contact with the material are well sealed, which can prevent water and oil; Use sealed butterfly valves at the discharge area to prevent air leakage; The induced draft discharge pipe section adopts flexible connections, which can be disassembled, cleaned, disinfected, sterilized, etc. at any time;
3. The air pre-treatment system adopts air filtration for middle and high school students, purifying the air to a level of 100000;
4. This unit uses PLC program to control the system circuit; The touch screen animation display process is operable, and variable operating parameters are automatically tracked and adjusted using fuzzy technology; Stabilize and safely adjust the atomizer with a frequency converter; Digital display of inlet and outlet air temperature, tower pressure, which can be set, etc.
