installation and platform, inspection of regulators and gas pressure, and propergrounding of the units and feed containers.

The OQ (Operation Qualification) included verification of the operation sequence,

such as system startup, flow of gas into the system, valve closing and vacuumgeneration, valve opening and release of products, air shock activation to clean the

filters, start of gas flow, and repeat of sequence.

The PQ (Performance Qualification) for the C33 Vacuum Conveyor system includedthe transfer of rice grains through a 2-inch diameter by 37-foot PVC tubing with avertical lift of 11 feet. About 45 lbs. of rice was re-circulated for a period of 4 hours(250 cycles). Approximately 0.45 cubic feet of rice (about 20 Lbs) was transferredin each cycle, corresponding to about 110 cubic feet in 4 hours. No malfunctioningof the system during the execution of the OQ/PQ was observed. The system iscapable of transferring bulk materials of several tons per day, all automatically.

The IQ, OQ, PQ validation of the C21 Vacuum Conveyor is similar to the C33 exceptthe unit included a PLC controller (programmable logic controller) for operating the

unit and a lower transfer capacity (0.12 cubic feet per cycle).

PIAB's new vacuum conveying system is completely enclosed, hygienic and safe,making it ideal for food and pharmaceutical industries, which demand an extremelyhigh degree of hygiene and safety in transferring ingredients and finished products.Powders and granules are ideal for vacuum conveying and a great number ofmaterials, even those that are health impairing and/or sensitive to humidity andcontamination, can be safely conveyed.
