The invention discloses a freeze-
drying plasma device. The device comprises an inner
barrel, blood storage columns, an air
inlet channel, isolation valves, condensation chambers and a
vacuum pump; anouter
barrel sleeves the outer side of the inner
barrel through the top end of the inner barrel, and the air
inlet channel penetrates through the outer barrel to communicate with the inner barrel; anactivated carbon filter screen, a nano
fiber filter screen and a stainless steel filter screen are sequentially inlaid in the inner cavity of the air
inlet channel, wherein the outer ends of a Y-shaped channel are correspondingly connected with the condensation chambers through the isolation valves, and the outer end sides of the condensation chambers are connected with refrigerating compressors through pipelines; and the
vacuum pump is connected to the Y-shaped channel on the front side of the isolation valves through the pipelines, and a spiral heating tube is arranged at the bottom of the inner side of the outer barrel. The spiral heating tube is used for keeping the inner barrel in a relatively constant temperature, and the
vacuum pump is used for enabling the interior of the inner barrel to be vacuum; the air in the inner barrel is replaced by a fan and the vacuum pump, so that the quality of air in the inner barrel is improved; and the
plasma in the inner barrel is frozen by utilizing the refrigerating compressors.
