Description
Technical field
The present invention relates to one kind circulation baking oven, in particular, it is related to a kind of low frequency level closed hot air circulation to dry
Case.
Background technology
Heated-air circulation oven air circulation system circulates air supply mode using blower fan, and wind cycle balance is efficient.Wind regime is by following
Ring air supply motor（Using noncontacting switch）Wind wheel is driven via heater, and hot blast is sent out, then via in air channel to baking oven
Room, then the air suction air channel after use is turned into wind regime recirculation, heating is used.Ensure indoor temperature uniformity.Work as because
When switch gate action causes temperature value to swing, the rapid recovery operation state of the circulatory system of blowing, until reaching design temperature
Value.But, the air inlet pipe of current heated-air circulation oven is arranged at the bottom of baking oven, and escaping pipe is arranged at the top of baking oven, and
Drip pan level is distributed, and in the drip pan set by level, temperature is gradually reduced hot blast, is caused in bottom drip pan and top drip pan
Dry materials degree it is different, particularly with the delicate material of the quality such as fruits and vegetables, it may appear that the excessive or moist situation of drying,
Qualification rate is low, wastes serious.
The content of the invention
Goal of the invention：Present invention aim in view of the shortcomings of the prior art, there is provided a kind of uniform drying, qualification rate are high
Low frequency level closed heated-air circulation oven.
Technical scheme：A kind of low frequency level closed heated-air circulation oven of the present invention, including casing and blower fan,
The casing is double-deck boxboard, and cavity is formed between double-deck boxboard, and the inside of the casing sets the drying chamber of level distribution, often
Individual drying chamber is sealing structure；
At the cavity that the air supply duct of the blower fan is arranged between double-deck boxboard into the part of casing, and by air-supply branch
Pipe accesses each drying chamber；The return air duct of the blower fan is arranged in the cavity between double-deck boxboard into the part of casing,
And each drying chamber is accessed by return air branch pipe.
The technical solution of the present invention is further defined as, the blowpipe accesses the bottom of each drying chamber.
Further, the return air branch pipe accesses the top of each drying chamber.
Further, also including wet-emitting blower, the dehumidifying pipelines of the wet-emitting blower access each drying chamber.
Further, the material of the outer layer boxboard of the casing is 304 stainless steel matt film coated plates, the internal layer of the casing
The material of boxboard is 304 stainless steel plates.
Further, the cavity filling aluminosilicate fiber cotton between the double-deck boxboard of the casing.
Beneficial effect：A kind of low frequency level closed heated-air circulation oven that the present invention is provided, by the drying for sealing
Room solves the problems, such as that dry materials degree is different, and the thermal efficiency is high, saving energy consumption, it is adaptable to the delicate material of the quality such as fruits and vegetables
When, all of nutritional ingredient of fruits and vegetables has been effectively retained, and dry uniformity is ensure that, qualification rate is high, produces real being good for
Health food.
Brief description of the drawings
A kind of structural representation of low frequency level closed heated-air circulation oven that Fig. 1 is provided for the present invention.
Specific embodiment
Technical solution of the present invention is described in detail below by accompanying drawing, but protection scope of the present invention is not limited to
The embodiment.
Embodiment 1：A kind of low frequency level closed heated-air circulation oven, its structural representation is as shown in figure 1, including case
Body 1, blower fan 2 and wet-emitting blower 4.
The casing 1 is double-deck boxboard, and cavity is formed between double-deck boxboard.The material of the outer layer boxboard of the casing 1 is
304 stainless steel matt film coated plates, rivet welding shaping, surfacing, without soldering, no marking, flatness is 3/1000mm.The casing
The material of 1 internal layer boxboard is 304 stainless steel plates, and argon arc is close to be welded into type, interior corner R arc transition, and through precision polishing, polishing at
Reason, surfacing is smooth, without dead angle, easy cleaning.Cavity filling aluminosilicate fiber cotton between the double-deck boxboard of the casing 1,
Heat-insulating property is good, and surface temperature is no more than 5 DEG C of environment temperature.
The inside of the casing 1 sets the drying chamber 3 of level distribution, and each drying chamber 3 is sealing structure, each drying
The inside of room 3 only sets a floor drip pan 6, it is ensured that the quality of drying.
At the cavity that the air supply duct 5 of the blower fan 2 is arranged between double-deck boxboard into the part of casing 1, and by sending
Wind branch pipe 8 accesses each drying chamber 3, and the blowpipe 8 accesses the bottom of each drying chamber 3.The return air duct of the blower fan 2
7 are arranged in the cavity between double-deck boxboard into the part of casing 1, and access each drying chamber 3 by return air branch pipe 9, described
Return air branch pipe 9 accesses the top of each drying chamber 3.Solve the problems, such as that dry materials degree is different by the drying chamber for sealing,
The thermal efficiency is high, saving energy consumption, it is adaptable to during the material of the quality such as fruits and vegetables delicacy, be effectively retained all of nutritional ingredient of fruits and vegetables,
And dry uniformity is ensure that, qualification rate is high, produces real healthy food.
