Operation principle illustrates:
Vacuum freeze drying is that article are placed in dry bucket after cryogenic freezing by pending article in cold-trap; Vavuum pump starts to vacuumize, and refrigeration system synchronously continues cold-trap space refrigeration; After vacuum reaches certain value, the ice condensed in article is sublimed into steam, and being congealed into ice again after moisture to the lower cold-trap wall of temperature is attached on cold-trap wall; After article moisture is fully extracted, vavuum pump and refrigeration system all quit work, and condense in ice on cold-trap wall by heating or naturally absorb heat and be melted into water and accumulate in bottom cold-trap, are finally discharged by water again; Whole freezing dry process terminates;
Mode of operation of the present utility model illustrates:
Pattern one: secondary cold-trap uses as catching hydroecium
1) the article freezing stage: respectively the insulation cover (19,20) of major and minor cold-trap (1) is covered after article being put into primary cold trap (3), refrigeration system starts refrigeration and article is refrigerated to temperature required (temperature is controlled by temperature sensor (4), this course synchronization freezes to major and minor cold-trap space, now electronic refrigeration two-port valve (16) is opening, and cold-producing medium can enter in major and minor cold-trap evaporimeter (2) simultaneously);
2) vacuumizing phase: laying for goods on drying frame (22), is placed on dry bucket (21) on primary cold trap mouth back cover by drying frame; Seal cover (23) is placed into (now major and minor cold-trap is all in sealing state) on secondary cold-trap mouth; Refrigeration system continues to carry out the low-temperature condition that freezes to keep in cold-trap to major and minor cold-trap, opens vavuum pump (15) simultaneously and vacuumizes; Along with the ice in time variations article is constantly sublimed into steam under the effect of vacuum and low temperature, steam congeals into ice again and is attached to major and minor cold-trap inwall after running into cryotrap wall, until the moisture in article is extracted completely, (vacuumize electric T-shaped valve in this process and open (17), major and minor cold-trap is connected state; Vacuum is controlled (5) by vacuum module);
3) bleeding stage: after article moisture is extracted, system is all out of service; Open draining valve (7), the ice of cold-trap inwall attachment is melted into water by absorbing environmental heat, finally by discharge pipe line (8) from Natural excrement in cold-trap (this process, draining electric T-shaped valve (11) is opened, and major and minor cold-trap drainpipe is connected state);
Pattern two: major and minor cold-trap is simultaneously as pre-freeze room with catch hydroecium and use;
1) the article freezing stage: by the 1st of pattern one) article are put into major and minor cold-trap simultaneously and carry out pre-freeze by step;
2) vacuumizing phase: laying for goods on two drying frames, covers upper dry bucket after drying frame being placed on primary cold trap mouth respectively; The 2nd of mode of operation common mode one) step;
3) bleeding stage: the 3rd of common mode one) step;
Pattern three: only use one of them cold-trap (illustrating to use primary cold trap)
1) the article freezing stage: after article are put into primary cold trap, the insulation cover of primary cold trap is covered refrigeration system start refrigeration article are refrigerated to temperature required, this process only freezes (now electronic refrigeration two-port valve is closed condition, and cold-producing medium only enters in primary cold trap evaporimeter) to primary cold trap space;
2) vacuumizing phase: laying for goods on drying frame, is placed on dry bucket on primary cold trap mouth back cover by drying frame; Now primary cold trap is all in sealing state; Refrigeration system continues to carry out the low-temperature condition that freezes to keep in cold-trap to primary cold trap, open vavuum pump carries out vacuumizing drying until article moisture is fully extracted (vacuumizing electric T-shaped valve in this process is closed condition, and major and minor cold-trap is not for being communicated with) simultaneously;
3) bleeding stage: after article moisture is fully extracted, system is all out of service; Open draining valve, the ice of primary cold trap inwall attachment is melted into water by absorbing environmental heat, finally by discharge pipe line from Natural excrement in cold-trap (this process, draining electric T-shaped valve is closed condition, and major and minor cold-trap drainpipe is not communicated with, and the water of thawing is only discharged from primary cold trap discharge pipe line).
