Abstract
The utility model relates to a multiple cold-source vacuum freezing and drying unit which is an improved vacuum freezing and drying unit and is suitable for the concentration and drying of the medicine. The multiple cold-source vacuum freezing and drying unit comprises a moisture acquisition unit, a vacuum drying box and a vacuum pump; the moisture acquisition unit is formed by that the periphery of a U-shaped condenser is welded with a condensing sheet and other structures; the multiple cold-source vacuum freezing and drying unit does not use a refrigerating machine and can select various cold-source; the temperature can reach minus 196 DEG, and various water absorbing agents can be selected. The utility model can also be used for the vacuum preservation of the manufactured product, the sealing of the ampoule, the extraction of the vacuum, air inflating, etc.; the air inlet of the multiple cold-source vacuum freezing and drying unit is provided with a bacillus filtration unit, which can defend the pollution of the manufactured product.
Description
The utility model is a kind of improved vacuum freezing drying device.Be applicable to hospital, medical colleges and schools, R﹠D institution's development and production biochemical drug and biological products, carry out concentrate drying.
At present, freeze drier all is traditional freeze drier.Produce the LGJ-1B type as Shanghai medical analytical instrument factory, U.S. Christ ALPHA produces family machine.These freeze driers are made up of refrigerator, drying box, condenser, vavuum pump and heater.During use goods are put in the drying box, open refrigerator give cold, through tens hours fully freezing after, drive vavuum pump and heater again and carry out drying.This class device must be provided refrigerator refrigeration for oneself, and single low-temperature receiver is adopted in cooling, has only a kind of purposes, minimum temperature-60 ℃.Need use cooling water.Because of the high pipeline of pressure is many, make complicated inconvenient maintenance.
The utility model is to provide a kind of improved multi-freezing pipe vacuum freezing drying device, without refrigerator, can adopt the low-temperature receiver of more than 20 kind of different temperatures.Can choose wantonly with a kind of replacement refrigerator, minimum temperature can reach-196 ℃, also have 10 simultaneously surplus kind of solid water absorbing agent, for selecting for use arbitrarily.
The utility model has been compared following advantage with the traditional cold lyophilizer:
The utility model traditional cold lyophilizer
1, can select for use more than 20 kind of low-temperature receiver refrigerator refrigeration to make low-temperature receiver
2, can select for use more than 10 kind of water absorbing agent not use
3, a kind of purposes of multiple use is arranged
4, the big cryosurface of cryosurface is little
5, minimum temperature reaches-196 ℃ of minimum temperatures-60 ℃
6, saving energy resource consumption energy is big
7, need not provide refrigerator for oneself and must provide refrigerator for oneself
8, few many with material with material
9, must use cooling water without cooling water
The utility model is by catching the moisture content device, vacuum drying chamber, vavuum pump composition.
Catch moisture content device (1) and form low-temperature receiver pond (4) by " U " type condenser (3), condensate film (2), on low-temperature receiver Chi Gai (6) is arranged, passage (5), the bottom has water absorbing agent dish (28) to form.Condensation chamber (29) air inlet (7) links to each other with vacuum chamber (15) gas outlet (17), and opposite side condensation chamber (29) gas outlet (30) links to each other with drier threeway bottle (25).Vacuum chamber (15) is a garden shape plexiglass tent (16), and condensation chamber (29) also is a garden shape plexiglass tent (31).
Vacuum drying chamber (14) is interior by metal frame (9), metal dish (10), and crown cap (13), bacterium filter (11) is equipped with at the center, air inlet switch (12), metal bottom (18), and heat insulation shutter board (20) is formed formation natural heating system.
Vavuum pump (22) connects magnetic valve (23), and vavuum pump gas outlet (24), drier threeway bottle (25) connects bacterium filter (26) air inlet switch (27) and forms the negative-pressure vacuum system of bleeding.Vavuum pump (22) is fixed on the vacuum pump bracket (19).
Embodiment:
Make condensation area increase 2 times at stainless steel " U " type condenser (3) peripheral solder stainless steel condensate film (2).This " U " type condenser (3) can make and catch moisture content efficient Senior Three doubly.Can select arbitrarily in the low-temperature receiver pond (4) and change low-temperature receiver, as: 1. sodium chloride 33 grams add trash ice 100 gram temperature and can reach-21 ℃.2. ethanol 105 gram trash ices 100 restrain-30 ℃.3. anhydrous calcium chloride 128 grams add trash ice 100 grams ,-40 ℃.4. anhydrous calcium chloride 143 grams add trash ice 100 grams ,-54 ℃.5. chloroform adds carbon dioxide dry ice ,-77 ℃.6. liquid nitrogen-196 ℃ grade is commonly used have 20 surplus kind.Suction dish (28) can select arbitrarily and change water absorbing agent below condenser (3), as: 1. anhydrous calcium chloride.2. dead plaster.3. natrium carbonicum calcinatum.4. anhydrous magnesium sulfate.5. phosphorus pentoxide.6. kind of water absorbing agent surplus the potassium hydroxide etc. 10 has low-temperature receiver Chi Gai (6) center roof vent (5) on the low-temperature receiver pond, condensation chamber vacuum chamber air inlet (7) and condensation chamber gas outlet (30) is housed simultaneously forms and catch moisture content device (1).Vacuum drying chamber (14) is interior by metal frame (9), metal dish (10), and crown cap (13), metal bottom (18) is the good material of conductive performance, loads onto heat insulation shutter board (20) and regulates motor (21) waste heat, forms the natural heating system.
When giving in low temperature refrigerator or low-temperature receiver, goods freeze to put into vacuum drying chamber (14) rapidly after the reality, put air cock (12) (27) into, open and connect switch (8), drive vavuum pump (22), magnetic valve (23) is breakdown automatically, when closing the anti-oil leakage gas of Shi Buhui, connect drier threeway bottle (25), but absorption portion moisture content and avoid entering in the vavuum pump, it is interior under certain vacuum condition that goods are put vacuum chamber (15), heats up naturally and refrigerated products generation temperature difference, and ice is distilled becomes hydrone, catch moisture content specially by condenser or water absorbing agent, thereby reach the purpose of low temperature dewatering drying.Open air inlet switch (27) air inlet when drying finishes, bacterium filter (26) can prevent that goods from polluting.Connect switch (8) when closing, open air inlet switch (27), can bleed or take out ampoule vacuum seal usefulness separately, in vacuum chamber (15), put palpus kept dry article well, put air cock (8) into but shutdown kept dry usefulness.When opening air inlet switch (27), drive vavuum pump (22) and inflate usefulness with the vavuum pump gas outlet.The time spent can not made ice bath or holding liquid usefulness when low-temperature receiver pond (4).
