A kind of energy-conservation processing of aquatic products dryer
The utility model relates to technical field of aquatic product processing, especially a kind of energy-conservation processing of aquatic products dryer.
At present, foodstuff dryer has utilization widely in food processing field, and the moisture in food is removed in its effect.If application number is the Chinese utility model patent of 201320317790.7, it discloses a kind of dryer for marine products processing, mainly comprise conveyer belt, heating plant and oven dry cabinet, heating plant comprises steam boiler and appendix, and hot gas is transferred in oven dry cabinet by appendix by steam boiler.It adopts steam to provide thermal source, environmental protection and can meet production requirement.But it is in use procedure, a large amount of hot gas also can be discharged by air outlet, causes waste.
Summary of the invention
The purpose of this utility model is the deficiency overcoming above-mentioned prior art, provides the aquatic product drying machine that a kind of structure is simple, energy-conservation.
To achieve these goals, the technical solution adopted in the utility model is: a kind of energy-conservation processing of aquatic products dryer, comprise frame, conveyer belt, transfer drive, heating plant, be arranged on the drying baker on central rack, it is characterized in that: described heating plant comprises steam boiler, appendix and the first aeration plate be arranged on bottom drying baker, the front portion of described frame is also provided with a preheating cabinet, preheating cabinet is connected by tail gas recycle pipe with the top of drying baker, tail gas recycle pipe is also provided with an air blast, a tube connector is also provided with in preheating cabinet, upper end and the tail gas recycle pipe of tube connector export and are connected, lower end is connected with the second aeration plate.
Further, the lateral wall of described drying baker and preheating cabinet is equipped with heat-insulation layer; Described drying baker and preheating cabinet sidewall all offer watch window.
The beneficial effects of the utility model are: structure is simple, by arranging preheating cabinet, can utilize further the tail gas of high temperature, can first to need dry product carry out preheating, product can be heated up faster after entering drying baker, raise the efficiency, energy-conserving and environment-protective.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of heating plant in the utility model.
Detailed description of the invention
As shown in Figure 1, 2, a kind of energy-conservation processing of aquatic products dryer of the utility model, comprises frame 1, conveyer belt 2, transfer drive 3, heating plant 4, the drying baker 5 be arranged on central rack.
Wherein, above-mentioned heating plant 4 comprises steam boiler 41, appendix 42 and is arranged on the first aeration plate 43 bottom drying baker.The front portion of frame 1 is also provided with a preheating cabinet 6, and preheating cabinet 6 is connected by tail gas recycle pipe 7 with the top of drying baker 5, and tail gas recycle pipe 7 is also provided with an air blast 8.In preheating cabinet 6, be also provided with a tube connector 9, the upper end of tube connector 9 exports with tail gas recycle pipe 7 and is connected, and lower end is connected with the second aeration plate 10.
In the present embodiment, the lateral wall of above-mentioned drying baker 5 and preheating cabinet 6 is equipped with heat-insulation layer; And all watch window is offered on drying baker 5 and preheating cabinet 6 sidewall.
Finally should be noted that; above content is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection domain; the simple modification that those of ordinary skill in the art carries out the technical solution of the utility model or equivalently to replace, does not all depart from essence and the scope of technical solutions of the utility model.
