Modelos Contínuos para Diferentes Tipos de Alimentação
Os secadores por atomização (LPG, YPG, GXP, ZLPG) atomizam continuamente a alimentação líquida transformando-a em pó seco; os secadores flash (XSG, Pneumático) transportam continuamente a torta úmida através de ar quente; os secadores de leito fluidizado (XF, ZLG) e de esteira (DW) movimentam continuamente material granular e a granel; o forno rotativo (HZG) e as unidades de condução a vácuo (CD, PLG, HG/GT, ZYG) realizam o processamento contínuo de sólidos a granel e pastas.
Por Que os Fabricantes Optam pela Secagem Contínua em Vez da Secagem em Lote
A vazão estável atende aos cronogramas de produção de alto volume sem tempo de inatividade entre lotes. O tempo de residência constante proporciona um teor de umidade mais uniforme ao longo de toda a produção. Menor custo de mão de obra por unidade produzida em comparação ao carregamento e descarregamento de lotes discretos.
