Specific embodiment
For the operating process for making present invention realization is easy to understand with creation characteristic, with reference to specific embodiment,
The present invention is expanded on further.
Instant freezer includes the first cross air blasting orifice plate plate face 1, the second cross air blasting orifice plate plate face 2, orifice plate perforate 3 with V shaped hole plate；
Instant freezer V-type AND DEWATERING FOR ORIFICE STRUCTURE is characterised by：First cross air blasting orifice plate plate face 1, the second cross air blasting orifice plate plate face 2 are 80mm wide,
Thickness is 1mm, and length is the hexahedron plate face of A；Pressed from both sides between first cross air blasting orifice plate plate face 1 and the second cross air blasting orifice plate plate face 2
Angle is θ；First cross air blasting orifice plate plate face 1, the second cross air blasting orifice plate plate face 2 are distributed two row radiuses for 5mm, and pitch of holes is 40mm
Orifice plate perforate 3, and two row orifice plate perforates are distributed in orifice plate center line both sides；First cross air blasting orifice plate plate face 1 and the second cross air blasting
The periodic arrangement successively of orifice plate plate face 2, and be unified continuous overall；This instant freezer orifice plate is installed on instant freezer guipure plane one
Side；The intersection of the first cross air blasting orifice plate plate face 1 and the second cross air blasting orifice plate plate face 2 to guipure plane distance be H.
Angle theta is according to the first cross air blasting orifice plate plate between first cross air blasting orifice plate plate face 1 and the second cross air blasting orifice plate plate face 2
The distance of the intersection of the cross air blasting orifice plate plate face 2 of face 1 and second to guipure plane is H determinations, and unit is：mm；Relation between the two
For：θ=π-2arcsin（20/（30+H））；In this example, H=100mm can obtain θ=π -2arcsin（20/（30+H））=π-
2arcsin（20/（30+100））=162°.
Depending on instant freezer orifice plate width A is according to instant freezer guipure width B, relational expression between the two is：A=B+50mm；This
In example, guipure width B=1200mm, therefore, instant freezer orifice plate width A=B+50mm=1250mm.
Depending on instant freezer orifice plate length C is according to instant freezer plenum chamber length D, relational expression between the two is：C=D；This example
In, instant freezer plenum chamber length D=8000mm, therefore, instant freezer orifice plate length C=D=8000mm.
Instant freezer orifice plate uses stainless steel material.
In this example, the balanced release of pressure is realized by orifice plate by the cooling air that blower fan blasts plenum chamber, when cold air is logical
Crossing orifice plate perforate 3 carries out pressure release pressure, and now the static energy of air is converted to dynamic pressure energy, makes to be discharged by orifice plate perforate and presses
To 8-20m/s, swiftly flowing cold air blows and hits the frozen food in V shaped hole plate lower section the air velocity transient rise of power, makes
The convection transfer rate increase of food side, reduces Prediction of Freezing Time of Foods, is effectively improved food freezing speed.By device to hole
Plate carries out numerical simulation using process, and analog result shows, the angle existed between V shaped hole plate plate face adjacent apertures makes by hole
The flow of cooled air that plate perforate is injected not at grade so that frozen food side is cooled the effective of air
Impact, compares with common straight orifice plate, and freeze-off time is substantially shortened.
A kind of instant freezer V shaped hole plate of the present invention；Quick-frozen food side heat convection system can effectively be increased
Number, reduces the freeze-off time of food, and a kind of new approaches are provided for research improves instant freezer freezing rate.
