Abstract

The invention provides an aseptic isolator for fixed automatic feeding and discharging on a vacuum freeze drier, which is characterized by comprising a frame component, wherein the frame component is provided with a visual operating window component and an aseptic transmission interface component; the visual operating window component is sealed by an airtight seal component on the frame component; one end of an air inlet pipe extends into the frame component, while the other end is connected with an air treatment unit; and an air treatment unit pipeline is connected with an exhaust fan. The aseptic isolator has the advantages of reducing the risk of artificial contamination, lightening the pollution of the product on operators and external environment, reducing a clean production area, and greatly improving the controllability of a production area so as to reduce operating cost and maintenance cost.

Description

technical field [0001] The invention relates to an aseptic isolator specially designed for the fixed automatic feeding and discharging of the vacuum freeze dryer. The material system creates a stable, low-contamination risk, and completely isolated Class A sterile area. Background technique [0002] The vacuum freeze dryer is a machine designed and manufactured using the principle of freeze-drying for freeze-drying water-containing substances, that is, the water-containing substances are cooled and frozen into a solid state, and then the water vapor is directly sublimated from the solid state under vacuum conditions; fixed automatic The feeding and discharging system connects the filling machine and the capping machine with the vacuum freeze dryer to form a whole, and realizes the automation of the feeding and discharging of sterile freeze-dried preparations. [0003] There are the following defects in the material feeding and discharging operation process of the existing v...
