Specific embodiment
For making the operating process of present invention realization be easy to understand with creation characteristic, with reference to specific embodiment,
The present invention is expanded on further.
Instant freezer orifice plate includes the first cross air blasting orifice plate plate face 1, orifice plate plate face 2 of just drying, the second cross air blasting orifice plate plate face
3rd, orifice plate perforate 4；Instant freezer AND DEWATERING FOR ORIFICE STRUCTURE is characterised by：First cross air blasting orifice plate plate face 1, orifice plate plate face 2 of just drying, the second side
Blowing orifice plate plate face 3 is wide 80mm, the hexahedron plate face of thick 1mm, long A；First cross air blasting orifice plate plate face 1 and orifice plate of just drying
Between plate face 2, angle is θ；First cross air blasting orifice plate plate face 1 and the second cross air blasting orifice plate plate face 3 are just being dried orifice plate plate face with first
2 midline vertical plane is that the plane of symmetry is symmetrical；First cross air blasting orifice plate plate face 1, orifice plate plate face 2 of just drying and the second cross air blasting orifice plate
Plate face 3 is distributed two row radiuses for 5mm, orifice plate perforate 4 of the pitch of holes for 40mm, and two row orifice plate perforates are distributed in orifice plate center line
Both sides；First cross air blasting orifice plate plate face 1, orifice plate plate face 2 of just drying, the second cross air blasting orifice plate plate face 3 periodic arrangement successively, and
For unified continuous entirety；This instant freezer orifice plate is installed on instant freezer guipure plane side, and just drying orifice plate plate face 2 and guipure
Plane is parallel；Distance between orifice plate plate face 2 and guipure plane of just drying is H.
First cross air blasting orifice plate plate face 1 and angle theta of just drying between orifice plate plate face 2 are according to orifice plate plate face 2 and the speed of just drying
The distance between jelly machine guipure H determines that unit is：mm；Relation is between the two：θ=π-2arctan（20/（50+H））, this example
In, therefore H=100mm can obtain：θ=π-2arctan（20/（50+H））=π-2arctan（20/（50+100））=165°.
Instant freezer orifice plate width A determines that 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=1200+50mm=1250mm.
Instant freezer orifice plate length C determines that according to instant freezer plenum chamber length D relational expression between the two is：C=D；This example
In, plenum chamber length D=8000mm, therefore, instant freezer orifice plate length C=D=8000mm.
Instant freezer orifice plate adopts stainless steel material.
In this example, the balanced release of pressure is realized by orifice plate by the air that blower fan blasts plenum chamber, when air passes through orifice plate
Perforate 4, carries out pressure release, and now the static energy of air is converted to dynamic pressure energy, makes the air for discharging pressure by orifice plate perforate
To 8-20m/s, swiftly flowing cold air blows and hits frozen food below orifice plate flow velocity transient rise, especially by side blow
Orifice plate plate face jet is hit to the cold air of food side, the convection transfer rate of frozen food side is effectively improved.Pass through
Numerical simulation is carried out using process to orifice plate, analog result shows, cross air blasting orifice plate plate face and just drying is deposited between orifice plate plate face
Angle make the flow of cooled air that injects by orifice plate perforate not at grade, be cooled frozen food side
Effective impact of air, is compared with commonly straight orifice plate, and freeze-off time is substantially shortened.
A kind of instant freezer orifice plate of the present invention；Can effectively intensified freezing food side heat convection, reduce
The freeze-off time of food, preferably improves traditional straight orifice plate single direction shock problem, is that research raising instant freezer freezes
Speed provides a kind of new approaches.
