Description
Technical field
The present invention relates to drying equipment technical field, a kind of heat-pump-type vacuum refrigeration-hot air convection joint food is particularly related to
Medicinal material dryer.
Background technology
Existing dry technology species is various, but the contradiction that cannot be reconciled between product quality and energy consumption mostly.For example, traditional
Although dryness in the sun process is simple, energy consumption is low, drying time is long, and efficiency is low, big by environmental factor restriction, easily causes product
Pollution, it is difficult to control product quality；Thermal Efficiency of Hot Air Drying is high, and device structure is simple, but because heating-up temperature and humidity are difficult to
Control, can cause product case-hardening, neutraceutical active ingredients loss, color, smell and taste quality deterioration；Vacuum freeze drying（It is lyophilized）
Carried out under low-temperature vacuum environment, food is clean, can be maximally maintained the color, smell and taste of food and Chinese medicine, but energy consumption compared with
Greatly, take more long.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of heat-pump-type vacuum refrigeration-hot air convection joint food medicinal material drying
Machine.
The drying machine includes vavuum pump, evaporator, freeze drying box, compressor, blower fan, condenser, capillary and hot bellows；Freeze
Dry case is connected with vavuum pump, and valve is set between freeze drying box and vavuum pump, and evaporator is placed in freeze drying box, and evaporator order connects
Capillary, condenser and compressor are connect, compressor connection evaporator constitutes refrigeration-heat pump cycle, side and blower fan in condenser
It is connected, and the side silicone filler, condenser opposite side is connected with hot bellows.
Wherein, net-like spacer is set in hot bellows, material two is placed on net-like spacer.
Evaporator is the space that ring-type copper pipe is impaled, and space is left in the middle of evaporator and places material one, is close to material one
Evaporator.Evaporator substitutes cold-trap in freeze drying box, because evaporator temperature is far below environment temperature, can steam environment reclaimed water
Gas is condensed in tube wall, plays the function of cold-trap, reduces pressure in drying box, and protect vavuum pump.Space is left in the middle of evaporator
Put for material, material is close to evaporator, the effect of high efficient heat exchanging can be reached.
The present apparatus makes full use of the energy of evaporator with heat pump and condenser：The cold produced using evaporator is freezed material
After crystallization, step-down is vacuumized to drying box with vavuum pump makes to crystallize water sublimate in material, the part moisture in dried material；Together
When, hot blast is produced using the thermal discharge heating dry air of condenser, redrying is carried out to another batch materials, take full advantage of heat
The energy of pump.
Above-mentioned technical proposal of the invention has the beneficial effect that：
1) drying efficiency is high, and energy consumption for drying is few, and material condition is good.
2) heat is absorbed from material using evaporator, while part moisture in dried material, using condenser
Thermal discharge heating dry air produces hot blast, and redrying is carried out to another batch materials, takes full advantage of heat-pump-type evaporator and cold
The energy of condenser；
3) evaporator temperature is far below environment temperature, and Water vapor condensation reduces pressure in drying box in tube wall in can making environment,
Protection vavuum pump.

Specific embodiment
To make the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and tool
Body embodiment is described in detail.
The present invention provides a kind of heat-pump-type vacuum refrigeration-hot air convection joint food medicinal material dryer.
As described in Figure 1, freeze drying box 3 is connected with vavuum pump 1 in the drying machine, and valve is set between freeze drying box 3 and vavuum pump 1
7, evaporator 2 is placed in freeze drying box 3, and evaporator 2 is linked in sequence capillary 9, condenser 6 and compressor 4, and compressor 4 is connected
Evaporator 2, constitutes refrigeration-heat pump cycle, and side is connected with blower fan 5 in condenser 6, and the side silica gel 10 is filled, condenser 6
Opposite side is connected with hot bellows 13.Net-like spacer 12 is set in hot bellows 13, material 2 11 is placed on net-like spacer 12.
Wherein, evaporator 2 is the space that ring-type copper pipe is impaled, and space is left in the middle of evaporator 2 and places material 1, makes thing
Expect that one 8 are close to evaporator 2.
The operation principle of the drying machine is：
Material needs that by drying process twice qualified products can be dried in the heat pump drier.Material is in freeze drying box 3
Primary drying (vacuum freeze drying) is inside carried out, evaporator 2 directly absorbs heat from freeze drying box 3, and temperature reduction, treats in freeze drying box 3
Temperature is reduced to when under the saturation temperature corresponding to moisture stress, and the moisture in material starts crystallization, when all being crystallized to moisture
Temperature-fall period terminates.Low-temperature condition is now maintained in case, while condensed steam, is dehumidifying in case；The reduction freeze drying box of vavuum pump 1
Pressure in 3, when under the saturation pressure corresponding to pressure in case is reduced to moisture temperature, the moisture in material starts distillation.When
When moisture content in material is reduced to a certain setting value, stop step-down, take out material, be ready for redrying.At the same time
Second batch materials are put into freeze drying box, previous step is repeated, so far first dry materials is finished.
Material carries out redrying in hot bellows 13（Heated-air drying）Process.Air is conveyed by blower fan 5 in hot bellows 13,
Air needed to turn into dry air by the dehumidifying of silica gel 10 before reaching in hot bellows 13, and it is right that dry air is carried out with condenser 6
Heat is spread, the dry air with dehumidifying effect is eventually become, material is dried.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, on the premise of principle of the present invention is not departed from, some improvements and modifications can also be made, these improvements and modifications
Should be regarded as protection scope of the present invention.
