Abstract

The invention discloses a low-ash plasma protein tubular membrane concentration technology. An original blood high level tank, a tubular centrifuge, two filter screen filters, two stirring tanks, a tubular membrane filtration device, a feeding pump and a circulating pump are adopted, and original blood in the original blood high level tank automatically flows into the tubular centrifuge through the gravity effect; blood cells and blood plasma in the original blood in the tubular centrifuge are separated, the blood plasma is conveyed to the first stirring tank from a blood plasma temporary storage tank after going through the first filter screen filter, then sequentially goes through the feeding pump, the second filter screen filter and the circulating pump, and is conveyed to the tubular membrane filtration device, the feeding pump provides the pressure needed by the filtering process of the tubular membrane filtration device, and the circulating pump increases the circulating flow and provides enough membrane surface flow velocity; and the blood plasma in the tubular membrane filtration device is concentrated, goes through a concentrate outlet, is sent to the second stirring tank, is conveyed to a spray drying tower through a conveying pump, and is dried to form plasma protein powder. The technology is advanced, and can realize the continuous feeding and continuous concentration processes.
