Description
Technical field
The utility model relates to a kind of vacuum system, particularly a kind of vacuum system of food freeze dryer.
Background technology
At present, the extensive Ying Yu of food freeze dryer in food service industry, to our life with huge benefit.Dryness storehouse needs to vacuumize fast after injecting food, and keeps vacuum state.Can produce a certain amount of steam owing to carrying out heating in dryness storehouse, in normal use procedure, pump group does not often reach the requirement vacuumized, and pump group is easily damaged.Have a strong impact on normal use.
Utility model content
For the deficiency in solving the problems of the technologies described above, the purpose of this utility model is: the vacuum system providing a kind of food freeze dryer, can overcome above-mentioned defect, ensures the vacuum in dryness storehouse.
The technical scheme that the utility model adopts for its technical problem of solution is:
There is provided a kind of vacuum system of food freeze dryer, comprise the dryness storehouse of food freeze dryer, dryness storehouse is connected with fast pump pump group and lasting aspiration pump group respectively by butterfly valve; Fast pump pump group comprises the first lobe pump and vacuum oil pump, and vacuum oil pump connects the first lobe pump, and the first lobe pump connects dryness storehouse by the first butterfly valve; Continue aspiration pump group and comprise the second lobe pump and water-ring vacuum pump, water-ring vacuum pump connects the second lobe pump, and the second lobe pump connects dryness storehouse by the second butterfly valve.
Wherein continue to be provided with vacuum solenoid and check-valves successively in the middle of the second lobe pump and water-ring vacuum pump in aspiration pump group.
Preferably, vacuum oil pump is six, and in being connected in parallel.Fast pump pump group adopts the cooperation of lobe pump and vacuum oil pump can rapid vacuumizing, makes dryness storehouse reach good using state within the shortest time.In normal use procedure, the frozen food in dryness storehouse carries out drying can produce a certain amount of steam, continues aspiration pump group and vacuumizes for the later stage.
Because the needs of rapid vacuumizing are so lobe pump and vacuum oil pump carry out combination bleeds, then because the later stage continue to keep vacuum because steam can be produced and then use the combination of lobe pump and water-ring vacuum pump to bleed.This combining form can meet use needs, has and can ensure use safety.Because during the normal use of dryness storehouse, a certain amount of steam can be produced, if do not adopt water-ring vacuum pump easily can cause the damage of pump.The power of water-ring vacuum pump is less simultaneously, compared with under the prerequisite of low power consuming, can ensure result of use.
Vacuum solenoid can prevent the pump oil of water-ring vacuum pump from backflowing effectively, contaminated vacuum system, and check-valves can stop current to flow backwards automatically, ensures dry run.
Compared with prior art, the utility model has following beneficial effect:
The utility model reduces energy consumption to a certain extent, and fast pump pump group and lasting aspiration pump group cooperatively interact, and can found ideal low air pressure condition for lyophilization storehouse.
Accompanying drawing explanation
Fig. 1 the utility model structural representation.
In figure: 1, fast pump pump group; 2, aspiration pump group is continued; 3, vacuum line; 4, the first lobe pump; 5, vacuum oil pump; 6, the first butterfly valve; 7, the second lobe pump; 8, water-ring vacuum pump; 9, the second butterfly valve; 10, check-valves; 11, dryness storehouse.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in Figure 1, the vacuum system of food freeze dryer described in the utility model, comprises the dryness storehouse 11 of food freeze dryer, and dryness storehouse 11 is connected with fast pump pump group 1 and lasting aspiration pump group 2 respectively by butterfly valve; Fast pump pump group 1 comprises the first lobe pump 4 and vacuum oil pump 5, and vacuum oil pump 5 connects the first lobe pump 4, first lobe pump 4 and connects dryness storehouse 12 by the first butterfly valve 6; Continue aspiration pump group 2 and comprise the second lobe pump 7 and water-ring vacuum pump 8, water-ring vacuum pump 8 connects the second lobe pump 7, second lobe pump 7 and connects dryness storehouse 112 by the second butterfly valve 9.Fast pump pump group 1 and lasting aspiration pump group 2 are all be connected dryness storehouse 11 by vacuum line 3, and butterfly valve is used for cut-offfing path.
Wherein continue to be provided with vacuum solenoid and check-valves successively in the middle of the second lobe pump 7 and water-ring vacuum pump 8 in aspiration pump group 2.Prevent the pump oil of water-ring vacuum pump from backflowing, contaminated vacuum system, check-valves can stop current to flow backwards automatically, ensures dry run.
Preferably, vacuum oil pump 5 is six, and in being connected in parallel.Fast pump pump group 1 adopts the cooperation of lobe pump and vacuum oil pump can rapid vacuumizing, makes dryness storehouse reach good using state within the shortest time.In normal use procedure, the frozen food in dryness storehouse carries out drying can produce a certain amount of steam, and the water ring pump continuing the use of aspiration pump group can avoid steam to the damage of pump, continues aspiration pump group and vacuumizes for the later stage.
When the utility model uses, open the first butterfly valve 6, fast pump pump group 1 carries out work, carry out fast pump, at utmost the gas in dryness storehouse 11 is drained only with the shorter time, then close the first butterfly valve 6, open the second butterfly valve 9, continue aspiration pump group 2 and carry out work, air is successively through the vacuum that three dry lobe pumps 7 and water-ring vacuum pump 8 keep dry in storehouse, and available less power maintains vacuum state.In whole exhaust dry run, initial stage vavuum pump group 1 and the ruly coordinated operation of dry vacuum group 2, farthest decrease the consumption of the energy, ensure that use safety and good result of use.
