Gentle on the product Low wear Low level of dehomogenization High conveying capacity Long transport distances Energy saving due to targeted transport air supply AZO®MULTIAIR dense phase conveying is a system that operates in the positive pressure range. The transport pressure range is between 1 and 4 bar positive pressure. The optimum transport pressure setting is based on the product and performance. This transport system is particularly dedicated for abrasive products such as PVC Dryblend and fiberglass-reinforced granulates as well as for pneumatic transport of foodstuffs such as breakfast cereals, instant products or milk powder with low levels of dehomogenization. In this optimized pressure vessel transport, the fluidization condition in the bulk material is maintained by blowing in secondary air. This means the coefficients of friction between the tube and produc are drastically reduced. The air quantity is added through standardized proportional valves, and this addition is controlled by the central control system. Optimizations for specific products are possible at any time. Plant safety is assured by special non-return valves positioned between the transport line and injector valves. These measures mean that transport can take place with a high belt loading rates and low speeds, without blocking the transport line. System and product wear is very significantly reduced compared to dilute phase transport. Low compressed air consumption, low filter surface load and small tube cross sections means the TCO (total cost of ownership) is reduced.
