Abstract
The utility model provides a vacuum freezing dryer, which is characterized in that a freeze-drying tank and a water catching device are connected into one unit; a hole with large caliber is arranged at the middle, and a mushroom valve is arranged. The design can effectively decrease the resistance force of the sublimation of water molecule, the water catching efficiency of the water catching device is raised to 99%, and the water content of a finished product is less than 1 %.
Description
Technical field
The utility model relates to a kind of vacuum freeze drier, and especially a kind of can the raising catches water rate vacuum freeze drier.
Background technology
Vacuum freeze drier is exactly containing a large amount of moisture content materials, and cooling in advance is frozen into solid, makes water vapour directly distil from solid then under certain vacuum condition, thereby reaches dry a kind of method.This method can be preserved biological today of biological products on the one hand, and freeze-drying has been widely used in industries such as bioengineering, biological products, antibiotic, veterinary drug and health products.
Traditional vacuum freeze drier is to take freeze drying box and water vessel to be respectively two casings, the middle large diameter pipeline that adopts connects, install the turnover of butterfly valve control air-flow on the pipeline additional, but because the caliber of butterfly valve restriction, the diameter of pipeline can not be very big, therefore, often form the distillation resistance, the influence distillation.The catching the water effect and can only accomplish 97% of water vessel, the moisture content of manufactured goods is greater than 3%.
Along with the development of biological medicine technology, freeze dryer is had higher requirement, especially some gene technology products often require the finished product moisture content less than 1%, and the traditional vacuum freeze drier of China is technical can not to satisfy its requirement.
Summary of the invention
The purpose of this utility model provides the vacuum freeze drier that water efficient is caught in a kind of raising.
For realizing above purpose, the technical solution of the utility model provides a kind of vacuum freeze drying, it is characterized in that freeze drying box and water vessel are combined as a whole, and the middle dividing plate that adopts is cut apart, and has horn-shaped port on the dividing plate, is provided with isolating valve on horn-shaped port.
Isolating valve in the middle of described freeze drying box and the water vessel adopts the dried mushroom valve.
The utility model adopts two casees conjuncted technical schemes, have wide-aperture horn mouth in the middle of the dividing plate, and adopt the dried mushroom valve as the isolating valve between freeze drying box and water vessel, can shorten the stroke that hydrone stream flows out freeze drying box, reduce the distillation resistance effectively, sublimation process is more complete, and actual gain of the present invention is water vessel efficient can be brought up to more than 99%, thereby makes the finished product moisture content less than 1%.The needs of biotech development have been satisfied.
Description of drawings
Fig. 1 is the structural representation of vacuum freeze drier.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, be the structural representation of vacuum freeze drier, a kind of vacuum freeze drying is characterized in that freeze drying box 1 and water vessel 2 are combined as a whole, and the middle dividing plate 3 that adopts is cut apart, and has horn-shaped port 4 on the dividing plate, is provided with isolating valve 5 on horn-shaped port 4.What the isolating valve 5 in the middle of described freeze drying box 1 and the water vessel 2 adopted is the hydraulic pressure dried mushroom valve that our company designs voluntarily, on the head of isolating valve 5 dome head is arranged, and the water conservancy diversion of gas when helping distilling makes that the frosting of water vessel is more even.Gas directly enters water vessel fast from household freezer, and passage shortens greatly, thereby has significantly reduced the distillation resistance., water vessel upper and lower side connecting screw rod compressor vacuumizes casing, and moisture content is distilled, and realizes vacuum drying.
Claims (2)
