Abstract

Patente de Invenção: <B>"PROCESSO PARA O TRATAMENTO DE MADEIRA VERDE E A ACELERAçãO DA SECAGEM DA MADEIRA VERDE"<D>. Um processo para o tratamento de madeira verde para tratar a madeira (24) em um estágio verde antes da cura para prevenir ou minimizar a formação de nódoa da madeira verde (24) como representado na fase 1 da fase inicial de aquecimento e resfriamento da madeira verde (24), e para curar ou secar a madeira verde (24) depois da fase inicial de aquecimento e resfriamento como representado na fase 2 para secagem subsequente. O processo para o tratamento e cura inclui o aquecimento da madeira verde (24) em um invólucro de aquecimento (12) para uma temperatura pré determinada acima de aproxidamente 120°F enquanto mantendo o conteúdo de umidade da madeira (24) perto do conteúdo de umidade original da madeira cortada (24), e depois imediatamente resfriando a madeira aquecida (24) com um fluido de resfriamento em uma temperatura e umidade substancialmente menores do que a temperatura e umidade relativa do invólucro de aquecimento (12) por um período de tempo suficiente para a madeira (24) alcançar substancialmente a temperatura reduzida do fluido de resfriamento para normalmente remover pelo menos aproxidamente 5% da umidade da madeira verde (24). A madeira verde (24) é condicionada pela etapa de resfriamento para as etapas de secagem subsequentes nas quais as taxas de remoção de umidade são substancialmente mais altas do que as taxas de remoção de umidade sob etapas de secagem convencionais anteriores.
