Abstract

''SECADOR DE SEMENTES COM CONTROLE AUTOMáTICO DE TEMPERATURA, DIREçãO E VAZãO DO FLUXO DE AR" Um secador de sementes controlado automaticamente (30) da presente invenção é adaptado para secar, eficiente e precisamente, sementes por controle automático da temperatura, direção e vazão do fluxo de ar do fluxo de ar escoando através das sementes dentro do compartimento (32,34). A invenção inclui um duto de ventilação superior (66) para fornecer uma fonte de ar quente, um duto de ventilação inferior (68) para fornecer uma fonte de ar à temperatura ambiente, e um duto de ventilação de mistura (70) para misturar as várias proporções de ar quente e à temperatura ambiente dos dutos de ventilação superior e inferior (66,68). O duto de ventilação de mistura (70) tem portas de descarga superior e inferior (72,74) formadas entre o duto de ventilação de mistura (70) e o compartimento (32,34), para fornecer o ar misturado ao compartimento acima ou abaixo da semente. As portas de descarga superior e inferior (52, 54) são formadas no compartimento acima e abaixo da semente, de modo que por controle da operação das portas de suprimento e descarga (62,64,52,54), a direção e a vazão de ar do ar misturado através da semente podem ser controladas precisamente por um controlador eletrónico. Muitos atuadores (58,60,82,96) controlam a operação das portas.
