Sin embargo, es muy difícil secar madera húmeda sin cierta pérdida de calidad, ya que parte de la madera es mucho más débil de lo normal. Debido a que las tensiones que se desarrollan durante el secado causan el problema de la madera húmeda, se deduce que la madera húmeda podría secarse mejor en un sistema que seque la madera sin desarrollar niveles de tensión tan altos... un sistema convencional que se seque más lentamente (como dije antes) o un secador de vacío que funcione correctamente para evitar grandes gradientes y tensiones de MC. Los sistemas de vacío por RF y de vacío por manta eléctrica desarrollaron tensiones y luego formaron un panal durante el secado, por lo que tendría que ser un tipo diferente de secado al vacío.
