The specific embodiment
Below in conjunction with the drawings and specific embodiments content of the present invention is described in further details.
Embodiment:
See also shown in Fig. 1 and 2.Energy-saving food drying baking room of the present invention mainly comprises: baking room 1, be arranged on air inlet and air outlet on the baking room 1, and the first ventilation door 10 is installed at the air inlet place, the second ventilation door 20 is installed at the air outlet place; Heat exchange of heat pipe 30 is installed between air outlet and air inlet, is used for recovery waste heat; Frequency conversion circulating fan 40 is installed between drying baking room glass top layer and glass smallpox, is regulated air quantity, can effectively improve the baking room vortex phenomenon, make whole baking room flow field, temperature field and moisture field even, reduce energy loss by VFC;
In circulating fan 40 fronts heater 50 is installed, is used for heating in the drying baking room; At the drying baking room top transparent glass layer 60 is installed, is convenient to solar radiation and comes in, make full use of solar energy as drying source; Be installed in the insulating 70 below the drying baking room glassy layer 60, be used to reduce the baking room heat to external radiation and to the dependence of conventional energy resource; Be installed in the deep bead 80 at baking room top, be used to reduce the difference pressuring loss that the air channel short circuit causes, increase the ventilation in food gap and the uniformity of cloth wind;
Be installed in first wind deflector 91 of passage below the drying baking room glass smallpox, it is even to be used to regulate baking room hot blast flow velocity, reduces the dead angle of humiture; And second wind deflector 92 that is installed in the drying baking room return air channel, be used to regulate drying baking room return air amount size.
Above-mentioned insulating 70 is heat-insulation layers of a kind of multifunction retractable type, is used to reduce heat to external radiation, saves a large amount of heat energy; This heat-insulation layer is selected the inorganic heat insulation material (composite silicate thermal insulation material) of nonhazardous for use, good stability and non-volatility, daytime, the insulating 70 of baking room was packed up, and was convenient to solar radiation and came in, make full use of solar energy as drying source, reduce dependence conventional energy resource; Overcast and rainy or evening, the insulating 70 of baking room trailed, and saved a large amount of heat energy, reduced conventional energy resource consumption.
Process with Cantonese cured meat and fish drying is an example, is described in detail the Energy Saving Control process of embodiment of the present invention:
Cured meat and fish food with the needs drying is placed in the drying baking room.In cured meat and fish food drying process, fine when sunny when daytime, the scalable insulating 70 of baking room can be packed up automatically, is convenient to sunlight and sees through glassy layer 60 and shine in, and makes full use of solar energy as drying source, reduces the dependence to conventional energy resource.At this moment, open circulating fan 40 and heater 50 in the drying baking room, open second wind deflector 92 maximum, first wind deflector 91 changes according to drying shed humiture environment and flow field, automatically open the appropriate location, guarantee humiture field and even flow field in the baking room, reduce dry blind area and dead angle, avoid heat waste.40 of circulating fans are regulated circulating fan 40 power output sizes according to dry each stage difference and humiture field demand automatically by VFC, thereby change drying shed air quantity size variation, play energy-saving and cost-reducing effect.Cured meat and fish food by with drying baking room in the heat convection of hot-air, the moisture heat absorption is evaporated to air, and obtains drying.
When dry cured meat and fish food needs ventilation, second wind deflector 92 is closed, first wind deflector 91 is opened maximum, the first ventilation door, the 10 and second ventilation door 20 is opened, and moisture is along with air is discharged drying baking room, the fresh cold air of utilizing hot wet gas current preheating to suck by heat exchange of heat pipe 30 (as shown in Figure 2), make full use of the heat energy of discharging gas, energy savings improves energy utilization rate, further reduces energy resource consumption, reduces cost.Equally, when overcast and rainy or evening, baking room insulating 70 can extend automatically, reduces the baking room heat to external radiation, saves a large amount of heat energy, reduces conventional energy resource consumption.
Energy-saving food drying baking room of the present invention adopts multinomial power-saving technology, makes the cured food product can rapid draing, energy savings, improve the qualification rate of cured food product, guarantee stay in grade, shorten cured food product arid cycle, cured food product color, shape are remained intact.
Above-listed detailed description is at the specifying of possible embodiments of the present invention, and this embodiment is not in order to limiting claim of the present invention, and the equivalence that all the present invention of disengaging do is implemented or change, all should be contained in the claim of this case.
