Embodiment Construction

[0007] Below in conjunction with embodiment accompanying drawing, the present invention is further described:

[0008] see attached figure 1 , install the motor (1) that controls the crank (6) on the top of the freeze-drying box (4), use the coupling (2) to connect the motor (1) and the outer drive turntable (3). In order to prevent vacuum leakage, the inner drive turntable (5) Set in the vacuum chamber of the freeze-drying box (4), the inner drive turntable (5) and the outer drive turntable (3) are magnetically coupled, and a rolling bearing is installed in them to reduce the frictional force generated when they rotate. Inside the freeze-drying box (4), the inner drive turntable (5) is also connected with the crank (6) through the coupling (2-1). The manipulator (7) is installed on the front end of the crank (6), so that the motor (1) can be used to drive the manipulator (7) to move.

[0009] see attached figure 1 , the whole process is carried out in a vacuum state. When...

Abstract

The invention relates to a method for fully-automatic on-line sampling of a freeze dryer. The method comprises that: in a freeze-drying box with a vacuum state, a motor drives an outer driving turnplate through a coupling; the outer driving turnplate adopts a magnetic coupling method to be connected with and drive an inner driving turnplate; the inner driving turnplate drives a manipulator on a crank through the coupling to grab a sample bottle placed on a board layer; the crank drives the manipulator to convey the sample bottle into an opened inner wicket of a vacuum chamber, the inner wicket is closed, an outer wicket is opened, the manipulator loosens, and the sample bottle drops off; and an operator takes off the sample bottle from one side of the outer wicket, and then the outer wicket closes automatically. The method overcomes the defect of a method that a long rod extends into the freeze-drying box to clamp a bottle manually for taking the bottle out of the middle vacuum chamber, realizes that sampling is performed in a vacuum state, and prevents polluted air from entering during the sampling or leakage caused by aging due to alternating low temperature and steam high temperature from impacting the quality of freeze-drying products in the freeze-drying box and discarding the products in bulk as useless; and the freeze-drying pass rate reaches over 99 percent.

Description

1. Technical field [0001] The invention relates to a fully automatic online sampling method for a freeze dryer, and relates to a method for fully automatic sampling of products in a vacuum state on the freeze dryer. 2. Background technology [0002] Vacuum freeze dryer, commonly known as freeze dryer, is a drying equipment widely used in medicine and food industries. to achieve the purpose of drying and dehydrating the material. At present, with the further integration of my country's pharmaceutical and food industries with international standards, the requirements for the use of freeze dryers in vaccines, blood products, biopharmaceuticals, medicines, health care products, etc. are getting higher and higher. Because all substances are sublimated in a vacuum state, the whole process is carried out in a sealed freeze-drying box, and the operator cannot directly understand the real state and condition of the freeze-dried product before the end of the entire freeze-drying proc...
