Description

Staged air drying device for food drier

Technical field

The utility model relates to a kind of staged air drying device for food drier, belongs to the matching component technical field of food processing equipment.

Background technology

Air-dry method in the existing food processing mainly contains following several: first kind is adopted hot blast air-dry, though the air-dry effect of hot blast is best, because the drop temperature height does not reach packing instructions.Second kind is adopted natural air drying, by blower fan the moisture content of food surface is dried up, and this method is energy efficient not only, and the later material that comes out can directly be packed.But its foraminous conveyer is linear structure as shown in Figure 1, and blower fan is installed in the guipure upper and lower side respectively, to blowing food surface moisture content is dried up up and down, though this kind method structure is comparatively simple, air-dry weak effect does not generally reach the effect of anticipation.Because end spaces is limited under the plant equipment, lower end blower fan 6 blows to the material surface by airduct again, and wind-force weakens to some extent, thereby can not effectively dry up the moisture content on material surface, and the material surface of often coming out later is attachment portion droplet often also.

Summary of the invention

The purpose of this utility model provides a kind of reasonable in design, compact conformation, the staged air drying device for food drier that air-dry effect is good.

The utility model is a staged air drying device for food drier, comprise body, place the drive unit and the driven shaft at two ends in the body, place the foraminous conveyer between drive unit and the driven shaft, place body upper 1# blower fan spaced apart, the 2# blower fan, the 3# blower fan, the 4# blower fan is characterized in that foraminous conveyer is three grades of staged settings in body, the inclined angle alpha of first order ladder guipure and second level ladder guipure is respectively 12～25 degree, and the angle of inclination beta of third level ladder guipure is 0～10 degree.

The afterbody of described first order ladder guipure can be connected transmission by driven shaft with the front portion of second level ladder guipure, and the afterbody of second level ladder guipure is connected transmission with the front portion of third level ladder guipure by driven shaft.

Described 1# blower fan can be corresponding to first order ladder guipure, the 2# blower fan is corresponding to the junction of first order ladder guipure and second level ladder guipure, the 3# blower fan is corresponding to second level ladder guipure, and the 4# blower fan is corresponding to the afterbody of third level ladder guipure, with the reasonable distribution air quantity.

The bottom of described foraminous conveyer also can be provided with drip tray.

The utility model adopts the transmission of three grades of staged foraminous conveyers, material is from the feed end charging, earlier by the blower fan on the first order ladder guipure, the globule of material upper surface is blown away, 2 groups of blower fans that this one-level ladder guipure upper end is provided with dry up the moisture content of material upper surface basically, when material arrives second level ladder guipure, because first order ladder guipure and second level ladder guipure have a difference in height, material freely overturns when falling, make the material lower surface up, by blower fan the globule of up material lower surface is dried up again.Adopt the transmission of multi-step formula, the material upper and lower surface is repeatedly overturn, and blower fan repeatedly dries up the moisture content on material surface with high wind.

Fig. 2 is an overall structure schematic diagram of the present utility model.

Among the figure, 1,1a, 1b, 1c, 1d, 1e be driven shaft, 2 is the 1# blower fan, and 3 is the 2# blower fan, and 4 is the 3# blower fan, 5 is drive unit, and 6 is the 4# blower fan, and 7 is drip tray, and 8 is foraminous conveyer, 9 is body, and 10 is first order ladder guipure, and 11 is second level ladder guipure, and 12 is third level ladder guipure.

The specific embodiment

The utility model is by body 9, place the drive unit 5 and the driven shaft 1a at two ends in the body 9, place the foraminous conveyer 8 between drive unit 5 and the driven shaft 1a, place body 9 tops 1# blower fan 2 spaced apart, 2

# blower fan
