CN2281082Y - Far infrared device for production line of instant rice - Google Patents

Abstract

The utility model relates to a far infrared device used for a production line of instant rice, which is composed of a plurality of far infrared pipes installed inside a baking box. A single far infrared pipe is composed of a metal pipe shell, far infrared radiation matter in the class of crystallization magnesium oxide, a resistance wire, a porcelain cap, a screw bolt, a nut, a lead wire, and an installation handle. The far infrared radiation matter heated by the resistance wire can diffuse far infrared waves which can be radiated into cooked rice on a transport net band for drying the cooked rice into the instant rice together with steam pressure, so the purpose of drying the rice synchronously from the inner part to the outer part can be obtained. The device can raise the production capacity of the existing product line of the instant rice by about two times; the energy consumption is reduced largely, and the quality of the rice is improved too.

Description

The far infrared device that the instant-rice production line uses

The utility model relates to the electrically heated drying device of a kind of application, particularly is suitable for a kind of far infrared device that the instant-rice production line uses.

Existing instant-rice production line, produce steam with boiler, earlier rice is cure into rice (making the complete αization of rice starch) with steam, steam and metallic aluminium with 0.4～0.7MPa carries out heat exchange in baking box then, producing 80～110 ℃ temperature, it is 9% instant-rice (this product is met then to restore behind water and is meal) that the rice of slaking is dehydrated water content.But the serious drawback of existing instant-rice production technology and equipment is, the energy consumption height, and production capacity is low.For example, the model that Chinese five state engineering consulting companies produce is the FBM-II production line, and production capacity only is about 35kg/h.Carefully tracing it to its cause, is that it is to transmit from outside to inside that heat is delivered on the rice because of in the dry run of instant-rice on production line, cause the inside of rice to be difficult to drying, so that have to elongate drying time, make the energy consumption height and production capacity is low, and the instant-rice quality also is affected.

At the above-mentioned drawback that prior art exists, the purpose of this utility model is that a kind of be particularly suitable for that the instant-rice production line makes that the rice that is used for to slaking dehydrates can significantly cut down the consumption of energy and improve the far infrared device of production capacity is provided.

Solution of the present utility model is, in the baking box that dehydrates, install far infrared device additional, this far infrared device is made up of the far-infrared tube of many same structures, every far-infrared tube has the Can at two mouthfuls at two ends, the far-infrared radiation material is housed in the Can, embedding in the far-infrared radiation material have a resistance wire that comes with Can insulation, the two ends of Can all have been fixed with the porcelain cap of insulating effect, all be fixed with on the porcelain cap and pass from the outer end that the porcelain cap puts in the Can inner end and the bolt that is connected with the resistance wire two ends respectively, be exposed on the bolt of porcelain cap outer end and all be connected with nut and be connected with lead, Can is externally connected with the installing handle that is used for installing far-infrared tube.

The many far-infrared tubes (for example 9～12) that will have said structure, be lifted in the baking box that dehydrates on the instant-rice production line by installing handle, connect 220V or 380V alternating voltage for the lead at every far-infrared tube two ends and come resistance wire in the heating tube, resistance wire is passed to outside far-infrared radiation material with heat energy, the far-infrared radiation material is subjected to thermal vibration, disperse far infrared wave, far infrared wave is radiated in the slaking rice on the production line guipure of advancing, makes it to be dried to instant-rice.Because far infrared wave has penetrability to the starch in the rice, thereby reached purpose from rice inside to the external sync drying.And carry out the take dry rice of heat energy that heat exchange produces by steam pressure merely, then can not possess this dual usefulness.

The employing of the utility model device makes existing instant-rice Production Line ability rise to 55～70kg/h from 35kg/h, not only make production capacity improve one times nearly, and the quality of rice (for example shot and rehydration) is improved.And the per kilogram instant-rice, the power consumption cost of paying only is 0.25～0.3 degree electricity, makes net profit increase by 100%～200%.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the structural representation of the single far-infrared tube of the utility model;

Fig. 2 is installed in the schematic diagram in the baking box on the production line for many far-infrared tubes among Fig. 1.

Referring to Fig. 1, the utility model far infrared device is made up of many single far-infrared tubes as shown in Figure 1.Every far-infrared tube has the Can 8 of both ends open, as adopting the irony pipe, far-infrared radiation material 6 is housed in the Can 8, far-infrared radiation material 6 can adopt the material of crystal magnesium oxide and so on, embedding in the far-infrared radiation material 6 have a resistance wire 7 that comes with Can 8 insulation, the two ends of Can 8 all have been fixed with the porcelain cap 4 of insulating effect, all be fixed with on the porcelain cap 4 and pass from the outer end that porcelain 4 puts in Can 8 inner ends and the bolt 1 that links to each other with resistance wire 7 two ends respectively, be exposed at and all be connected with nut 3 on the bolt 1 of porcelain cap 4 outer ends and crimping is fixed with lead 2, Can 8 is externally connected with the installing handle 5 that is used for installing far-infrared tube.

Referring to Fig. 2 and Fig. 1,9～12 far-infrared tubes with structure shown in Figure 1 are fixed in the baking box 11 on the instant-rice production line shown in Figure 2, can adopt bolt 9 and nut 10 assemblies that the top of the installing handle 5 of far-infrared tube is fixed on appropriate location in the baking box 11 when installing and fixing.As seen from Figure 2, during work, rice evenly is layered on by hopper 14 and transmits above the guipure 12, enters to cook after the case 13 abundant slakings, enters that drying becomes instant-rice in the baking box 11 again.
