ESTE ESTUDO ABORDA O DESENVOLVIMENTO DE UM TRANSPORTADOR PNEUMáTICO DE SóLIDOS EM FASE DENSA E BAIXA PRESSãO PARA A INDúSTRIA DE PET FOOD, FOCADO NO TRANSPORTE DE PELLETS. A METODOLOGIA INCLUI A CRIAçãO E TESTE DE UM PROTóTIPO INDUSTRIAL UTILIZANDO UM SOPRADOR DE AR COMO FORçA MOTRIZ, GARANTINDO TRANSPORTE A BAIXA VELOCIDADE E PRESSãO. PARA MINIMIZAR PULSAçãO E ESTABILIZAR A PRESSãO, FOI DESENVOLVIDA UMA VáLVULA DE CONTROLE DE PRESSãO BASEADA NA TEORIA DA PLACA DE ORIFíCIO. ESTA VáLVULA AJUSTA A PRESSãO PARA REGULAR A VELOCIDADE DE TRANSPORTE, EVITANDO QUEBRA DE MATERIAL E ENTUPIMENTOS. OS RESULTADOS PRELIMINARES MOSTRAM QUE A VáLVULA MANTéM UM PEQUENO DIFERENCIAL DE PRESSãO, CRUCIAL PARA O TRANSPORTE SEGURO E EFICIENTE. OS PRóXIMOS PASSOS ENVOLVEM TESTES DE TRANSPORTE DE MATERIAL E MELHORIAS CONTíNUAS NA VáLVULA
THIS PAPER ADDRESSES THE DEVELOPMENT OF A LOW-PRESSURE DENSE-PHASE PNEUMATIC SOLIDS CONVEYOR FOR THE PET FOOD INDUSTRY, FOCUSING ON PELLET TRANSPORTATION. THE METHODOLOGY INCLUDES DEVELOPMENT AND TESTING AN INDUSTRIAL PROTOTYPE USING AN AIR BLOWER AS THE DRIVING FORCE, ENSURING LOW-SPEED AND LOW-PRESSURE TRANSPORTATION. TO REDUCE PULSATION AND STABILIZE PRESSURE, A PRESSURE CONTROL VALVE BASED ON THE ORIFICE PLATE THEORY WAS DEVELOPED. THIS VALVE ADJUSTS THE PRESSURE TO REGULATE THE TRANSPORTATION SPEED, PREVENTING MATERIAL BREAKAGE AND BLOCKAGES. PRELIMINARY RESULTS INDICATE THAT THE VALVE MAINTAINS A SMALL PRESSURE DIFFERENTIAL, CRUCIAL FOR SAFE AND EFFICIENT TRANSPORTATION. NEXT STEPS INCLUDE MATERIAL TRANSPORTATION TESTS AND CONTINUOUS IMPROVEMENTS TO THE VALVE
