Carry by the conveyer of baked goods and be enclosed among thermal insulation member and the water receptacle, in being passed through, heat by the thermal source on top by baked goods.At this moment, amount is not when distribute the outside while hot, the part of its heat is reflected by the water receptacle of below, be used to heating again by baked goods, when the temperature on the conveyer surpasses predetermined temperature, open the heat extraction mouth that is arranged on the thermal insulation member immediately, at short notice temperature inside is reduced to desirable scope.According to such control, just guaranteed the stable of internal temperature.

Below, by illustrated embodiment the present invention is described, wherein:

Fig. 1 is the profilograph of continous roaster;

Fig. 2 is the amplification view along II among Fig. 1-II line;

Fig. 3 is the cutaway view along III among Fig. 2-III line.

In Fig. 1, the 10th, the continuous food-baking device relevant with the present invention.Continuous food-baking device 10 shown in this embodiment is a purpose with the barbecue eel, and it is constructed as follows: be provided with the white burning device A that is made of a pair of the 1st roaster 11 and the 2nd roaster 12 that the eel that is used for cutting open does not add the white burning in flavoring juice ground; The eel that to roast through this broiler is steamed the soft device 13 that steams; That gives that the eel steamed adds flavoring juice adds flavoring juice device 14; 3 couples of broiler B that form by the 3rd roaster 15; The chain delivery device 17 that eel carries out freezing refrigerating plant 16 and above-mentioned each device is connected together will be roasted.In addition, the 32nd, the sorter that carries out sorting by the weight of the Broiled Dish after freezing.

In this continuous food-baking device 10, employed white burning device A and broiler B have roughly the same structure.This can be illustrated by Fig. 2 and Fig. 3.In broiler shown in Figure 2, framework 21 upper supports that are welded by L shaped steel have chain delivery device 17.The chain of chain delivery device 17 is by chain link 19 two ends of elongated pin 18 of ining succession, and is wound on the sprocket wheel at conveyer two ends, and aforesaid chain link 19 can move along elongated of the guide rail 20 that is made of L shaped steel.This structure was with well-known structure was roughly the same in the past.

Around chain delivery device 17, longitudinally disposed a plurality of thermal insulation members 22 and water receptacle 23, surround and form tunnel-like.Its upper support has infrared heater 29, is formed in the apparatus for baking of the white burning device A of inside of thermal insulation member or broiler B etc. thus.That is, the thermal insulation member 22 that constitutes broiler is to insert in the casing of being made by thin stainless steel by inorganic material such as calcium silicates or mineral wool and the heat-insulating material of these good heat resistances to constitute.Directly go up bolting to aforesaid framework 21 during formation, or go up bolting again by hinge.Be arranged on the thermal insulation member 22 on the top of aforesaid frame 21, different when being arranged on the side are not used bolt, remain on the intrinsic position by deadweight.

Far-infrared heater 29 is bearing on the framework 21 by auxiliary stand (not going out among the figure).That is, be fixed with fuel distribution tube on the top of framework 21 by auxiliary stand (not shown), this fuel distribution tube is stretched to the below, pass thermal insulation member 22, some burners hang down in its underpart.Rely on the interval of adjusting between framework 21 and the auxiliary stand, the position of a part of burner is moved up and down.

Being arranged on the following water receptacle 23 of aforementioned chain delivery device 17, is by the side from aforesaid frame 21, resembles can transfer to the slotting drawer of desk to insert ground and insert the dark flat vessel formation of about 5cm, and its upper surface is made minute surface with stainless steel precision.Like this, the part of the far infrared that throws from the top is gone out by the bottom reflection of the water surface of water receptacle 23 and light, and prevents that heat scatters and disappears, and this heating that is applied to food is effective.And, in flat vessel, adding entry, the water in the flat vessel is gasified by the broiler temperature inside, in case broiler is inner dry, is convenient to get rid of from chain delivery device 17 flavoring juice that falls and the part food that burns.

Far-infrared heater 29 is to load onto far infrared wave filter 30 below the pottery of gaseous fuel heating in the present embodiment.Far-infrared heater 29 its heat releases partly are longilineal, and 4 far-infrared heaters are installed by crisscross direction.As shown in Figure 3,29X and 29Y represent different directions in length and breadth.Infrared ray by the gas fuel combustion emission becomes far infrared by far infrared wave filter 30.

Regulate for the temperature inside that centers on by thermal insulation member 22, particularly, can adopt and have heat extraction mouth 24 on the superincumbent thermal insulation member, perhaps on the exhausted pad member 22 of side, be provided with scavenge port 25 these two kinds of modes of switch voluntarily as the device of cooling usefulness.Heat extraction mouth 24 is designed to a chimney-like, places on the thermal insulation member 22 that is carried by framework 21, makes its atmosphere opening in the workshop.The 26th, be used for the butterfly valve of switch heat extraction mouth 24, when temperature inside when the temperature of defined is following, it is equivalent to a normally close valve that is closing, and when internal temperature rises to when too high, opens valve.Scavenge port 25 is rotatably connected on the position of the thermal insulation member 22 that covers on chain delivery device 17 sides by hinge 27, can be in the position of closing by switch knob 28 controls, its main application is to be used for inner cleaning, but rise to when too high at baking temperature, also can open it, internal temperature is descended rapidly to take a breath.

Because white roaster inside of burning device A and broiler B etc. is incubated by thermal insulation member 22 and water receptacle 23, so the heat that is applied by far-infrared heater 29 can be used in by baked goods expeditiously.And, according to the character of far infrared, by being heated, so can obtain good cured effect by the inside of baked foods.In addition, when the internal temperature of roaster is lower than predetermined temperature range, can increases to far-infrared heater 29 gas supplied amounts temperature is risen.Equally, when internal temperature is higher than predetermined temperature range, can reduces gas delivery volume temperature is descended.When temperature is too high, owing to have little time the adjustments of gas quantity delivered, at this moment can the butterfly valve 26 of opening installation on aforementioned heat extraction mouth 24, rely on the mode that high temperature air is discharged to regulate temperature.And, be to regulate temperature, can also console switch handle 28, a part that makes thermal insulation member 22 is opening laterally, but this method is of little use.

As shown in Figure 3, pass through, be provided with peristome at white entrance and exit place of burning device A and broiler B in order to make chain delivery device 17.Because heat might be distributed from this peristome, so be preferably in the preparation room, tunnel (not shown) that " コ " font is installed in the below in the peristome outside of opening, present embodiment is the example explanation with the eel broiler, and the present invention can certainly be used for the roaster of other food.
