Specific embodiment
For the operating process for realizing the utility model is easy to understand with creation characteristic, with reference to specific embodiment party
Formula, is expanded on further the utility model.
Blowing-type instant freezer orifice plate includes positive blowing orifice plate plate face 1, orifice plate cambered surface 2, orifice plate perforate 3；Blowing-type instant freezer
AND DEWATERING FOR ORIFICE STRUCTURE is characterised by：Positive blowing orifice plate plate face 1 is the orifice plate plate face of width 80mm, A long；Orifice plate cambered surface 2 is radius R, cambered surface
Angle is 45 ° of arc surface；The chord plane of orifice plate cambered surface 2 is in the same plane with positive blowing orifice plate plate face 1；Orifice plate perforate 3 half
Footpath is 5mm, is 40mm along groove direction pitch of holes；Orifice plate cambered surface 2 be distributed 3 row orifice plate perforates 3, adjacent two row orifice plate perforate 3 it
Between angle be 11.25 °, and between adjacent two row orifice plate perforate 3 cambered surface distance be 35mm；Positive blowing orifice plate plate face 1 and orifice plate
Cambered surface 2 is in periodic arrangement, and unified overall for what is be connected with each other；This blowing-type instant freezer orifice plate is installed on instant freezer guipure
Side, and positive blowing orifice plate plate face 1 is parallel with guipure plane；The distance between positive blowing orifice plate plate face 1 and guipure are 70mm.
The radius R of orifice plate cambered surface 2, is determined by cambered surface between adjacent two row orifice plate perforate 3 apart from L；Relation between the two is：
R=16L/π；In this example between adjacent two row orifice plate perforate 3 cambered surface apart from L=35mm, therefore, the radius R=16L/ π of orifice plate cambered surface 2=
16*35/π=178mm。
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, instant freezer guipure width B=1200mm, therefore, instant freezer orifice plate width A=B+50mm=1200+50=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 length C=D=8000mm.
Blowing-type instant freezer orifice plate is manufactured using 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
When crossing orifice plate plate face release pressure, now the static energy of air is converted to dynamic pressure energy, makes to discharge the sky of pressure by orifice plate perforate
To 8-20m/s, swiftly flowing cold air blows and hits the frozen food in orifice plate lower section gas velocity transient rise, especially by hole
Plate cambered surface jet effectively improves the air supply mode of traditional single direction to the cold air of food surface.Used by orifice plate
Process carries out numerical simulation, and analog result shows, the angle existed between orifice plate cambered surface adjacent apertures makes to be penetrated by orifice plate perforate
The flow of cooled air for entering not at grade so that frozen food side is cooled effective impact of air, with mesh
The preceding common straight orifice plate for using compares, and freeze-off time is substantially shortened.
A kind of blowing-type instant freezer AND DEWATERING FOR ORIFICE STRUCTURE described in the utility model；Quick-frozen food side pair can effectively be increased
The stream coefficient of heat transfer, reduces the freeze-off time of food, and a kind of new approaches are provided for research improves instant freezer freezing rate.
