A kind of energy-saving vacuum freeze dryer
Technical field
The utility model relates to Freeze Drying Technique fields, more particularly to a kind of energy-saving vacuum freeze dryer.
Background technique
Freezing type drier is that compressed air is forced through evaporator progress heat exchange and is dropped according to freeze drying principle
Temperature makes gaseous water and oil in compressed air condense into the water and oil of liquid, and dust by isobaric cooling, by certainly
Outside dynamic water trap discharge machine, to obtain a kind of machine of clean compressed air.
Existing freezing type drier include mostly compressor, heat exchanger, condenser, moisture trap, by hot gas
Road valve, throttle valve and automatic drain valve, in freezing type drier work, air is directly pumped by freezing type drier from the external world
A series of processing are carried out, but exists enter inside freezing type drier since outside air carries a large amount of dusts in this way, so that cold
The case where jelly formula dryer inner accumulation dust, occurs, and will affect the service life of freezing type drier itself in this way, existing
Freeze dryer usually only freezes and air-drying function, without having the function of storage refrigeration object, and the copper pipe evaporation of existing freeze dryer
Device is mostly to have a fin-type, and this evaporator freezes that area is little, and condensed water is not in evaporator icing when being easy to cause pumping
And be inhaled into vacuum pump, so that vacuum pump is impaired.
Utility model content
(1) technical problems to be solved
The technical problem to be solved by the present invention is to provide a kind of energy-saving vacuum freeze dryers, are frozen in the prior art with overcoming
The problem of moisture container enters vacuum pump when dry machine occupies larger freezer volume and pumping.
(2) technical solution
In order to solve the above technical problems, the utility model provides a kind of energy-saving vacuum freeze dryer, comprising: cool chamber, it is described
Hothouse 1, plate layer 2, Copper-tube Evaporator 3 and fan 4 are provided in cool chamber, the inner wall of the cool chamber front end is equipped with multiple
Strip projected parts block, the strip projected parts block combine to form the plate layer 2, and the hothouse 1 is the inside of the cool chamber front end
Space, the Copper-tube Evaporator 3 are located at the rear of the hothouse 1, and the fan 4 is located at the rear of the Copper-tube Evaporator 3,
The Copper-tube Evaporator 3 is connected with compressor 6, and the compressor 6 is located at outside the cool chamber, and the rear end of the cool chamber connects
It is connected to vacuum pump 5.
Further, the front end of the cool chamber is equipped with end cap 7.
Further, seal washer is equipped among the end cap 7 and the cool chamber.
Further, it is connected between the Copper-tube Evaporator 3 and the compressor 6 by condenser pipe.
Further, it is connected between the cool chamber and the vacuum pump 5 by exhaust tube.
Further, the Copper-tube Evaporator 3 is the Copper-tube Evaporator of non-finned.
Further, the cool chamber is cylindrical hollow structure.
(3) beneficial effect
A kind of energy-saving vacuum freeze dryer of the utility model, its structure are simple and convenient to operate, are provided in its cool chamber
Hothouse can make hothouse as container to be used to store some vegetables, save the area of freezer, while setting in the cool chamber
It is equipped with the Copper-tube Evaporator of non-finned, so that the area of freezing is bigger, condensed water is avoided and does not freeze and be inhaled into vacuum pump and lead
Cause vacuum pump damage.
Detailed description of the invention
Fig. 1 is a kind of structure chart of energy-saving vacuum freeze dryer of the utility model.
Wherein: 1 being hothouse, 2 be plate layer, 3 be Copper-tube Evaporator, 4 be fan, 5 be vacuum pump, 6 be compressor, 7 be
End cap.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
Refering to fig. 1, a kind of energy-saving vacuum freeze dryer of the utility model, comprising: cool chamber, in the present embodiment, the cool chamber
In be provided with hothouse 1, plate layer 2, Copper-tube Evaporator 3 and fan 4, wherein the inner wall of cool chamber front end be equipped with multiple strips it is convex
Bittiness, which combines to form plate layer 2, and the surface of the plate layer 2 is used to place some vegetables for needing to freeze, and adds simultaneously
Water removal is evaporated to vegetables after heat, hothouse 1 is the inner space of cool chamber front end, for be stored in internal vegetables into
Row is dried, and Copper-tube Evaporator 3 is located at the rear of hothouse 1, and in the present embodiment, which is that non-finned is evaporated
Device, the Copper-tube Evaporator 3 is for the vegetables in freeze drying chamber 1 when freezing, and the Copper-tube Evaporator 3 can will remain when vacuumizing
Condensate liquid be frozen on copper pipe, avoid condensate liquid from being extracted from exhaust tube, fan 4 is located at the rear of Copper-tube Evaporator 3, freezing
Fan 4 can dry to hothouse 1 in the process, achieve the effect that make vegetables to be freeze-dried by the effect of Copper-tube Evaporator 3, should
Copper-tube Evaporator 3 is connected with compressor 6 by condenser pipe, which is located at outside cool chamber, for providing refrigeration effect,
The rear end of cool chamber is connected with vacuum pump 5 by exhaust tube, which is used to extract out the air in cool chamber, this implementation
In example, the front end of cool chamber is provided with end cap 7, is put into after vegetables and needs to be closed the end cap 7, at the same the end cap 7 and cool chamber it
Between be equipped with seal washer, prevent gas leakage, which is cylindrical hollow structure, convenient for storing some refrigerated vegetables.
A kind of energy-saving vacuum freeze dryer of the utility model, its structure are simple and convenient to operate, are provided in its cool chamber
Hothouse can make hothouse as container to be used to store some vegetables, save the area of freezer, while setting in the cool chamber
It is equipped with the Copper-tube Evaporator of non-finned, so that the area of freezing is bigger, condensed water is avoided and does not freeze and be inhaled into vacuum pump and lead
Cause vacuum pump damage.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
