Spray Dryer
Chinese Medicine Special Spray Dryer
Time：2018.03.21
Chinese herbal extract is extracted from the plant's root diameter leaves, especially the alcohol extraction process. It contains high sugar powder and is easily softened and melted under high temperature. The ordinary centrifugal spray can no longer meet the requirement of drying. In response, the company organized a group of capable technical forces summed up the successful experience of designing and manufacturing spray dryers in the past few years, collecting the strengths of the same type of products in the same industry at home and abroad, and researching and developing through precise and repeated process calculations and numerous experimental tests. The special spray drying unit for traditional Chinese medicine was promoted to some well-known pharmaceutical companies.
1. The height of the tower tower has been adjusted accordingly. This not only ensures that the tower wall is not reached before the powder is dried, but also that the hot air residence time of the powder is ensured to complete the low-temperature drying; the tower wall is provided with a jacket cold air cooling device to ensure the material The liquid will not adhere to the tower wall due to localized high temperatures resulting in softening, melting or even coking; the taper increases, the air cone is mounted on the cone, and the compressed air shocks the cylinder body with a compressed air and sucks in the cylinder. The powder on the body was shot down smoothly.
2. All the contacts with the materials in the mainframe adopt plane or arc transitions, and the contact surfaces are polished and polished to handle (absolutely thrown to 10 or more), to avoid trachoma, dead ends, and eliminate material blocking; the entire unit is in contact with the material The material is made of stainless steel to ensure that the material is not contaminated; the transmission parts in contact with the material are sealed well and can be waterproof and oil proof; the discharge valve is operated with a sealed butterfly valve to prevent air leakage; the air intake and discharge pipe sections are connected by live connection; Dismantle, disinfect, sterilize, etc. to meet GMP requirements.
3. the air and processing system uses junior high three air filters, purify the air up to 100,000.
4. The unit uses the PLC program to control the system loop; the touch screen animation shows the process flow, which has operability, variable operation parameters to achieve automatic tracking and adjustment of fuzzy technology; the inverter is used to adjust the atomizer stably and safely; the power regulator controls the intake air temperature. Accuracy can reach positive and negative 2 to minimize energy consumption; inlet, outlet, tower temperature, tower pressure can be accurately set and so on.
