Description
Technical field
The utility model is related to vacuum freeze drying field, and in particular to a kind of vacuum freeze drier.
Background technology
Vacuum Freezing & Drying Technology, as a kind of new dry technology, is to utilize sublimation principle, by wet stock relatively low
At a temperature of be frozen into solid-state, then reduce material environmental pressure near vacuum under, make moisture therein direct without liquid
Gaseous state is sublimed into, finally makes the dry technology of material dewatering.Vacuum freeze drier(Hereinafter referred to as freeze dryer)It is to utilize vacuum
A kind of equipment of Freeze Drying Technique dried material.
In the pre-freeze freeze dryer of conventional small original position, cold-trap is cylindrical metal structure, and outer surface is wound with evaporator coil,
The heat of cylindrical wall will be absorbed when coil pipe internal refrigerant flow evaporates, reaches and exists to cylindrical wall cooling, by internal steam
Cylinder inner wall is frozen into ice, so as to play water vessel effect.Material frame is internally provided with cold-trap, material frame is provided with several layers of gold
Belonging on dividing plate, dividing plate has the material disc for filling material, bottom having heaters.During vacuum freeze drying, heater work,
To the energy needed for the ice distillation offer of material.So in whole cold-trap, periphery is the extremely low cold-trap wall of temperature, and there is temperature centre
The higher heater of degree.The heat of heater can not only be supplied to material, while cold-trap wall can be radiated, influence the temperature of cold-trap wall
Degree, adds energy consumption for cooling, influence and catches water effect.
Utility model content
Primary and foremost purpose of the present utility model is to provide a kind of vacuum freeze drier, and it can effectively overcome drawbacks described above.
To achieve the above object, the utility model is implemented using following scheme:
It is provided with a kind of vacuum freeze drier, including columnar cold-trap, cold-trap and places dried material to be frozen
Bin, it is characterised in that:The upper and lower of bin is respectively arranged with horizontally disposed thermal insulation board.
Further scheme is:
It is provided with the outer tube wall of cold-trap on the outer tube wall at the evaporator of coiled, the trap mouthful of cold-trap and coil pipe, disk is set
The entrance of pipe is connected with the outlet of compressor, and the outlet of coil pipe is connected with the outlet of condenser.
Thermal insulation board is constituted for XPS plate outsourcing heat reflection aluminium foil.
Bin includes being provided with the material for containing material on the upside of the metal partion (metp) that stratiform is intervally arranged, metal partion (metp)
Having heaters is set on the downside of disk, metal partion (metp).
By setting thermal insulation board in cold-trap in above-mentioned technical proposal, thermal insulation board radiation-inhibiting transmission effect improves cold-trap
The effect of water is caught, energy consumption for cooling is reduced.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the front view of cold-trap;
Fig. 3 is the side view of cold-trap.
Embodiment
In order that the purpose of this utility model and advantage are more clearly understood, the utility model is entered with reference to embodiments
Row is illustrated.It should be appreciated that following word is only to describe one or more of specific embodiments of the present utility model,
Considered critical is not carried out to the protection domain of the specific request of the utility model.
The technical scheme that the utility model is taken as shown in Figure 1, 2, 3, a kind of vacuum freeze drier, including columnar
The bin 12 for placing dried material to be frozen is provided with cold-trap 11, cold-trap 11, the upper and lower of bin 12 is respectively arranged with level
The thermal insulation board 15 of arrangement.By setting thermal insulation board 15 in cold-trap 11, the radiation-inhibiting transmission of thermal insulation board 15 effect improves cold-trap 11
The effect of water is caught, energy consumption for cooling is reduced.
Further scheme is at the evaporator 13 that coiled is provided with the outer tube wall of cold-trap 11, the trap mouthful of cold-trap 11
Outer tube wall on coil pipe 14 is set, the entrance of coil pipe 14 is connected with the outlet of compressor, the outlet of coil pipe 14 and condenser
Outlet is connected.Specifically scheme is:The outlet of condenser and the entrance of device for drying and filtering are to connection, the outlet of device for drying and filtering
It is connected with the entrance of capillary module, the outlet of capillary module is connected with the entrance of evaporator 13, the outlet of evaporator 13
It is connected with the entrance of compressor.
In refrigeration systems, state and temperature of the refrigerant in different components are differed, the refrigeration of compressor discharge
Agent is pressure high temperature hot gas, and highly pressurised liquid is become after first passing through condenser radiating and cooling, after become low pressure after throttling arrangement
Liquid, then become low-pressure gas by the absorption external heat of evaporator 13, finally enter from compressor air suction mouthful, from exhaust outlet row
Go out, complete a kind of refrigeration cycle.In this circulation, refrigerant absorbs heat from the side of evaporator 13, and is discharged from condenser side
The heat of absorption, reaches the purpose to the side material cooling of evaporator 13.Ingenious utilization refrigerant moves towards arrangement in the utility model,
The pressure high temperature hot gas that compressor is discharged first is bypassed in the coil pipe 14 set at 11 mouthfuls of cold-trap on lateral wall, is reached to cold-trap
The purpose of 11 mouthfuls of heatings;Simultaneously from 11 mouthfuls of cold-trap lay out after refrigerant temperature accordingly reduce, can also improve refrigeration cycle efficiency,
The effect of killing two birds with one stone taken.
Further, thermal insulation board 15 is constituted for XPS plate outsourcing heat reflection aluminium foil.Thermal insulation board 15 is shaped as rectangular slab
Block.Bin 12 includes being provided with the material disc for containing material on the upside of the metal partion (metp) that stratiform is intervally arranged, metal partion (metp), gold
Belong to and having heaters is set on the downside of dividing plate.
It is connected in addition, the outlet of coil pipe 14 can be divided into the entrance of branch road A and branch road B two-way respectively with evaporator 13,
Condenser, device for drying and filtering and capillary module are set gradually along the flow direction of refrigerant on branch road A, branch road A front end, which is set, adjusts
Save and be provided with magnetic valve on the valve body of its conducting state, branch road B.By enabling refrigeration of branch road A, B realization to cold-trap 11 respectively
With the conversion of deicing function.
In summary, the utility model can realize the purpose of prevention 11 mouthfuls of icings of cold-trap, while compared with conventional method,
