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.
Instant freezer includes the first orifice plate cambered surface 1, the second orifice plate cambered surface 2, orifice plate perforate 3 with ripple AND DEWATERING FOR ORIFICE STRUCTURE；Instant freezer
It is characterised by with ripple orifice plate：Ripple orifice plate plate face is R, cambered surface by the first orifice plate cambered surface 1, the second orifice plate cambered surface 2, cambered surface radius
Angle be 45 ° of arc surface circulate successively it is circumscribed form, the chord plane of all arc surfaces is in the same plane；First orifice plate cambered surface
1st, the equal distribution radius of the second orifice plate cambered surface 2 are the orifice plate perforate 3 of 5mm, and adjacent orifice plate perforate 3 is centered on the center of circle where circular arc
11.25 ° of rotation is symmetrical, and arc length is 35mm between adjacent orifice plate perforate 3；5 row are uniformly distributed along orifice plate cambered surface groove direction
Pitch of holes is the orifice plate perforate 3 of 35mm；This instant freezer orifice plate is installed on above instant freezer guipure, ripple orifice plate chord plane and instant freezer
Guipure plane is parallel, and the distance between ripple orifice plate chord plane and instant freezer guipure plane are 70mm.
Cambered surface radius R determines by arc length L between adjacent orifice plate perforate 3, arc between cambered surface radius R and adjacent orifice plate perforate 3
The relation of L long is：R=16L/π；In this example, L=35mm, accordingly, it is determined that cambered surface radius R=16L/ π=16*35/ π=178mm.
Depending on instant freezer ripple orifice plate width A is according to instant freezer guipure width B, relational expression between the two is：A=B+
50mm；In this example, guipure width B=1200mm, therefore, quick-frozen corrugating machine orifice plate width A=B+50mm=1250mm.
