Technical field
The present invention relates to a kind of temperature-adjustable food constant temperature tray rack based on phase-change heat-exchange, belongs to food heat-insulation
Equipment technical field.
Background technique
In school, factory and some fast food restaurants, food can be contained in window with pallet, convenient for the personnel selection that has dinner,
Because the time for eating meals for the personnel that have dinner is often not quite identical, need to get out vegetable in advance, ready-made food is placed on guarantor
It is kept the temperature in warm cabinet, waits staff when having dinner that the food Sheng in thermal insulation cabinet is drawn eater, food is made to peddle and contain
It is not easy to cool during taking.
Currently, the structure of common thermal insulation cabinet one kind as disclosed in the Chinese patent that Authorization Notice No. is CN202269743U
The structure of dish platform is sold in more lattice heat preservations, and the dish box for holding vegetable is placed on the panel on dish platform, is set inside the thermal insulation cabinet of dish platform
There are heater box and heater, the heater in thermal insulation cabinet can heat the water inside heater box, protect using hot water to vegetable
Temperature.
But for above-mentioned warm stage using non-phase transformation hot water heat supply mode, heat load is small, for thermally labile, uneven, appearance
Easily influence the mouthfeel of food；Simultaneously as the size and location of heater places limitation, it is difficult that entire warm stage is made to be in uniform
Heated state；Moreover, some vapor that the hot water that above-mentioned warm stage is used to be kept the temperature generates can directly be contacted with dish box,
Heat preservation is easy the grunge pollution entrained by dish box or during holding, and in order to guarantee the quality of food, water for heating is general
It will not all reuse, lead to water resource waste.Above-mentioned warm stage is open by design, therefore will be carried out daily internal clear
Reason, time-consuming and laborious, use cost is difficult to improve.
Summary of the invention
It is an object of the invention to overcome drawbacks described above existing for existing food heat-insulation equipment, propose a kind of based on phase inversion
The temperature-adjustable food constant temperature tray rack of heat under the premise of guaranteeing food quality and mouthfeel, passes through the phase of water energy saving
Transformation heat, guarantees the temperature of food service tray frame, and the adjusting of temperature can be carried out by simple mode.
Proposed by the present invention is a kind of temperature-adjustable food constant temperature tray rack based on phase-change heat-exchange, and structure includes support
Plate rail 1, heating device 5, vacuum pump exhaust tube 6, water-supply-pipe 7, vacuum pump 10, air inlet pipe 13, drainpipe 16, vacuum pump exhaust tube
6 and water-supply-pipe 7 connect with the rear end of heating device 5；Wherein heating device 5 is set to 1 bottom outside of tray rack, and water-supply-pipe 7 is set to
1 lower right side of tray rack, drainpipe 16 are set to 1 left lower of tray rack, and air inlet pipe 13 is set to 1 right upper portion of tray rack.
Advantages of the present invention:
1) heat transfer uses phase-change heat-exchange mode, and compared with traditional non-phase transformation hot water heating, heat load is big, for thermostabilization,
Temperature is uniform；
2) heat source is separated with pallet, food in pallet will not be polluted；
3) change of pallet upper plate area will not influence the food temperature of required guarantee；
4) water is in inside closed tray rack and circulates, can be energy saving without changing water daily；
5) without all carrying out detachable cleaning to entire tray rack daily, cleaning trays frame upper surface is only needed, the amount of labour is alleviated；
6) internal deflector can guarantee that the condensed water on top smoothly flows down；
7) pass through super-hydrophobic coat with deflector inside tray rack and handle the drop spring heat exchange, it can be achieved that water vapour condensation,
Also classical dropwise condensation, and then enhanced heat exchange be can promote, be not easy to be corroded, it can be with automatically cleaning.

Specific embodiment
As shown in Figure 1, a kind of temperature-adjustable food constant temperature tray rack based on phase-change heat-exchange, structure includes tray rack
1, heating device 5, vacuum pump exhaust tube 6, water-supply-pipe 7, vacuum pump 10, air inlet pipe 13, drainpipe 16；Wherein heating device 5 is set
In 1 bottom outside of tray rack, water-supply-pipe 7 is set to 1 lower right side of tray rack, and air inlet pipe 13 is set to 1 right upper portion of tray rack, draining
Pipe 16 is set to 1 left lower of tray rack, and 7 rear end of water-supply-pipe connects external fluid delivery conduit road, and the rear end connection of vacuum pump exhaust tube 6 is true
Sky pump 10.
The generally closed hollow cavity of the tray rack 1 guarantees that its internal heating water will not be by food pollution；Its
Middle part is equipped with the deflector structure of a recess, and the liquid, it can be achieved that vapor condensation is made of declined board 2, riser 3 and inclined board 4
Drop spring heat exchange, also can promote the dropwise condensation of vapor；The inner and outer surfaces of tray rack 1 are equipped with super-hydrophobic coat, guarantee support
Plate rail 1 is not easily susceptible to the influence of food grease stain, easy to clean.
It is -100KPa ~ 0KPa that the side panel upper right corner of the tray rack 1, which is equipped with model MD-S800V(range)
The temperature indicator 12 of digital display pressure vacuum gauge 11 and model TA4-SNR, for show 1 internal cavity of tray rack pressure and
Temperature value.
The middle part of the vacuum pump exhaust tube 6 is equipped with 1 flange form butterfly valve 8 and connects for controlling pipeline opening and closing, its rear end
Connect the minipump 10 of model RV0100C.
The middle part of the air inlet pipe 13 is equipped with 1 flange form butterfly valve 14 for controlling pipeline opening and closing.
The middle part of the water-supply-pipe 7 is equipped with 1 shut-off valve 9 for controlling pipeline opening and closing, and its rear end connection is external to supply water
Pipeline.
The drainpipe 16 is equipped with 1 shut-off valve 15 close at tray rack 15-20cm for controlling pipeline opening and closing.
The heating device 5 uses electric heating heat-supplying mode, automatically adjusts temperature control box, digital display temperature-control instrument, K by PID
Type warms galvanic couple, cast aluminium heating plate composition, and operating power 50w-10kw, heating temperature is 20 DEG C ~ 450 DEG C.
Its working method specifically comprises the following steps:
1) shut-off valve 9 is opened, by water-supply-pipe 7 to the water for being filled with 3 ~ 4L inside tray rack 1, is then shut off shut-off valve 9；
2) flange form butterfly valve 8 is opened, vacuum pump 10 is made by the suction of exhaust tube 6 in negative pressure inside tray rack 1, by pressure gauge 11
Show negative pressure value, negative pressure value set according to vegetable required temperature (negative pressure value as in the tray rack of sealing, required temperature
Corresponding pressure value when lower vapor coagulates, the temperature are then corresponding saturation temperature；If vegetable required temperature is 45 DEG C
When, negative pressure value is set as 0.090MPa, and when vegetable required temperature is 55 DEG C, negative pressure value is set as 0.084MPa, temperature needed for vegetable
When degree is 65 DEG C, negative pressure value is set as 0.076MPa), when reaching set negative pressure value, close vacuum pump 10 and butterfly valve 8；
3) start 1 bottom of tray rack heating device 5 heated, when internal water reach negative pressure corresponding to saturation temperature when boil
It rises, steam flow to 1 internal cavity top of tray rack, heat release is re-condensed into water on top, under under the action of vapour pressure
