L'invention porte sur un appareil polyvalent d'extraction et de concentration automatiques haute vitesse et haute efficacité. Ledit appareil peut fonctionner à l'état dynamique-linéaire, non supercritique ou supercritique et le solvant qui le recouvre peut être récupéré automatiquement lors du fonctionnement dudit appareil. Ce dernier peut être utilisé dans le domaine de la médecine traditionnelle chinoise, le génie chimique, l'industrie alimentaire et analogues. Grâce à cet appareil, on allie les procédés automatiques d'extraction, concentration, séparation, purification et récupération de solvant dans un circuit fermé afin de satisfaire aux besoins de production BPF. On peut utiliser des solvants mélangés ou seuls dans l'appareil et ces solvants peuvent être recyclés ou récupérés automatiquement par le système de l'appareil, la concentration des solvants pouvant être réglée automatiquement de façon linéaire. La vitesse d'extraction peut être accélérée par l'utilisation d'une oscillation ultrasonore. La vitesse de concentration et la vitesse de récupération des solvants peuvent être augmentées grâce aux techniques de la température, des micro-ondes, la réduction de la pression, etc., opérations durant lesquelles l'extraction de la température et de la pression peut être réglée de manière linéaire.
