Abstract
The utility model provides a kind of freeze dryer cold-trap, comprising: cold-trap housing, which is provided with steam entry; Cold-trap inner coil pipe, is positioned at this cold-trap enclosure interior; It is characterized in that, between this steam entry and this cold-trap inner coil pipe, be provided with flow apron.In the freeze dryer cold-trap that the utility model provides, water vapour distribution is comparatively balanced, thus, the frost of cold-trap cold surface attachment also will be relatively more even, both given full play to the ice fishing ability that it is maximum, turn avoid because water vapour is frozen in " ice blocks up " that the nearest cold surface of entrance occurs in a large number.
Description
Technical field
The utility model relates to a kind of freeze dryer cold-trap.
Background technology
The fields such as pharmacy, food, biology, chemical industry have been widely used in due to current vacuum freeze drier.More domestic enterprises had introduced some pharmaceutical purpose freeze dryers from the U.S., Germany in recent years successively, workshop is found by batch production, freeze dryer is due to the reason on Earlier designs, there is water vapour condenses too concentrated in cold-trap, easily cause " ice blocks up " and the problem of ice fishing poor-performing, can not bone dry because cold-trap blocking, have impact on the quality of product.Because the quality of cold-trap performance directly has influence on effect or production efficiency, therefore make improvements, be very important to improve ice fishing ability.
Utility model content
Feature and advantage of the present utility model are partly stated in the following description, or can be apparent from this description, or learn by putting into practice the utility model.
For overcoming the problem of prior art, the utility model provides a kind of freeze dryer cold-trap, comprising: cold-trap housing, which is provided with steam entry; Cold-trap inner coil pipe, is positioned at this cold-trap enclosure interior; It is characterized in that, between this steam entry and this cold-trap inner coil pipe, be provided with flow apron.
Preferably, the height of this flow apron is greater than the height of this cold-trap inner coil pipe.
Preferably, the top of this flow apron and bottom are equipped with multiple through-hole structure.
By reading description, those of ordinary skill in the art will understand the characteristic sum content of these technical schemes better.
Accompanying drawing explanation
Below by with reference to accompanying drawing describe the utility model particularly in conjunction with example, advantage of the present utility model and implementation will be more obvious, wherein content shown in accompanying drawing is only for explanation explanation of the present utility model, and do not form restriction of going up in all senses of the present utility model, in the accompanying drawings:
Fig. 1 is the side view of the freeze dryer cold-trap of the utility model embodiment.
Detailed description of the invention
As shown in Figure 1, the utility model provides a kind of freeze dryer cold-trap, comprising: cold-trap housing 1, which is provided with steam entry 2; Cold-trap inner coil pipe 3, is positioned at this cold-trap housing 1 inner; It is characterized in that, between this steam entry 2 and cold-trap inner coil pipe 3, be provided with flow apron 4.And the height of this flow apron 4 is greater than the height of cold-trap inner coil pipe 2.
In the present embodiment, the top of this flow apron 4 and bottom are equipped with multiple through-hole structure.Flow apron 4 plays a part barrier air, when the air-flow distilling out from freeze-drying container is by cold-trap entrance, some just disperses up and down along flow apron and flows backward, another part then flows from both sides, skewback two side direction porch backward, the flow apron being arranged on freezing chamber air flow inlet place so just plays good shunting action, increase the water vapour amount at rear, cold-trap chamber, make water vapour distribution in cold-trap chamber comparatively balanced.Thus, the frost of cold-trap cold surface attachment also will be relatively more even, both given full play to the ice fishing ability that it is maximum, turn avoid because water vapour is frozen in " ice blocks up " that the nearest cold surface of entrance occurs in a large number.
Above with reference to the accompanying drawings of preferred embodiment of the present utility model, those skilled in the art do not depart from scope of the present utility model and essence, and multiple flexible program can be had to realize the utility model.For example, to illustrate as the part of an embodiment or the feature that describes can be used for another embodiment to obtain another embodiment.These are only the better feasible embodiment of the utility model, not thereby limit to interest field of the present utility model that the equivalence change that all utilization the utility model descriptions and accompanying drawing content are done all is contained within interest field of the present utility model.
