Rieco has offered a Negative/Vacuum type conveying system which is specially designed to operate with a negative pressure and used to convey ingredients for the premix coffee and sugar through special conveying rotary airlock valves.
The material is pneumatically conveyed through their respective pneumatic conveying lines with the help of the diverter valve. The selection of diversion of the pneumatic conveying line, to any specific surge hopper can be attained through a selector switch provided on the control panel.
Bin mounted bag filters are used for capturing the dust generated while conveying and also venting out fresh air to the atmosphere.
Weighing and batching systems are used to precisely fill the blender with Non-Dairy Cream (NDC) Powder, Forming Creamer Material, and Sugar. The weighing hopper takes weight measurements, and the feeders continue to release material until a set weight is reached within the hopper. This triggers and gives a signal to the feeder to stop further blending, after mixing all the ingredients thoroughly well – this blended pre-mix coffee powder is then passed through the Vibro sieve, to get the desired particle size at the outlet. The material is then conveyed to the storage silo and discharged through a metal detector before packaging. It detects the presence of metal particles, if any and the final Pre-mix coffee power is then discharged to the packaging system.
