Description

A kind of upper and lower impact type quick freezing machine orifice plate air return structure
Technical field
The utility model belongs to quick-frozen food technical field, is related to a kind of upper and lower impact type quick freezing machine orifice plate air return structure, More particularly to a kind of air return structure for improving instant freezer space availability ratio.
Background technology
Upper and lower impact type quick freezing machine orifice plate exists in recent years as a kind of device for improving instant freezer cold air jet uniformity Food service industry has obtained widely applying, but the breakthrough too not big to the design of air air return structure in orifice plate, conventional Upper and lower impact type quick freezing machine air return structure is all connected with orifice plate, and air return method is also from orifice plate downside return air, such time Wind mode causes the space availability ratio of instant freezer system to be greatly lowered, and prevents the economy of instant freezer from effectively being carried It is high.At present, by changing upper and lower impact type quick freezing machine air return structure, the research for effectively improving instant freezer space availability ratio is not yet sent out It is existing.Therefore, related research also needs to the unremitting effort of various countries' researcher.
The content of the invention
The utility model proposes a kind of upper and lower impact type for the defect of the existing upper and lower quick-frozen orifice plate air return structure of impact type Instant freezer orifice plate air return structure.
The technical solution of the utility model includes the new upper and lower impact type quick freezing machine orifice plate air return structure of design, improves quick-frozen The measures such as machine space availability ratio.Specifically technical scheme is:
Upper and lower impact type quick freezing machine orifice plate air return structure includes that upper impact orifice plate plate face, lower impact orifice plate plate face, orifice plate are opened Hole, return air channel;Upper and lower impact type quick freezing machine orifice plate return air is characterised by:And upper impact orifice plate plate face and lower impact orifice plate plate face It is parallel to each other, spacing is 150 ~ 180mm;Instant freezer guipure from it is upper impact orifice plate plate face and lower impact orifice plate plate face between passage Pass through, belt surface is parallel with orifice surface;Return air channel is located at AND DEWATERING FOR ORIFICE STRUCTURE both sides;Return air channel is highly 200mm, section It is shaped as rectangle, a length of 600mm, a width of 130-180mm;The spacing of adjacent return air channel is 200mm;It is upper impact orifice plate plate face with Lower impact orifice plate plate face is uniformly distributed radius for 4-7mm, and pitch of holes is the round hole of 20-40mm.
Upper impact orifice plate plate face is parallel to each other with lower impact orifice plate plate face, and spacing is 155-175mm.
Upper impact orifice plate plate face is parallel to each other with lower impact orifice plate plate face, and spacing is 160mm.
Return air channel cross-sectional width H determines according to upper impact orifice plate plate face with lower impact orifice plate plate face space D, between two kinds Relation is:H=D-20mm.
The aperture of orifice plate perforate and pitch of holes determine according to instant freezer design parameter.
Upper impact orifice plate plate face is uniformly distributed radius for 5mm with lower impact orifice plate plate face, and pitch of holes is opened for the circle of 30mm Hole.
Upper and lower impact type quick freezing machine orifice plate air return structure is integrally made of stainless steel material;Stainless steel material performance is low The quick-frozen field performance of temperature is good.
A kind of upper and lower impact type quick freezing machine orifice plate air return structure described in the utility model;Can effectively change existing The air return structure of upper and lower impact type quick freezing machine, solves the problems, such as upper and lower impact type quick freezing machine air return structure low space utilization, carries The overall space availability ratio of system high, effectively improves the yield of unit volume instant freezer.
Brief description of the drawings
Fig. 1 is a kind of schematic three dimensional views of upper and lower impact type quick freezing machine orifice plate air return structure of the utility model;
In Fig. 1,1, side-impact orifice plate plate face;2nd, downside impact orifice plate plate face;3rd, orifice plate perforate;4th, return air channel.
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.
Upper and lower impact type quick freezing machine orifice plate air return structure includes upper impact orifice plate plate face 1, lower impact orifice plate plate face 2, orifice plate Perforate 3, return air channel 4;Upper and lower impact type quick freezing machine orifice plate return air is characterised by:And upper impact orifice plate plate face 1 and lower impact opening Plate plate face 2 is parallel to each other, and spacing is 160mm;Instant freezer guipure is between upper impact orifice plate plate face 1 and lower impact orifice plate plate face 2 Passage pass through, belt surface is parallel with orifice surface;Return air channel 4 is located at AND DEWATERING FOR ORIFICE STRUCTURE both sides;The height of return air channel 4 is 200mm, cross sectional shape is rectangle, a length of 600mm, a width of 150mm;The spacing of adjacent return air channel 4 is 200mm;Upper impact opening Plate plate face 1 is uniformly distributed radius for 5mm with lower impact orifice plate plate face 2, and pitch of holes is the round hole 3 of 30mm.
The cross-sectional width H of return air channel 4 impacts orifice plate plate face 1 and the space D determination of lower impact orifice plate plate face 2 according to upper, both Between relation be:H=D-20mm;According to upper impact orifice plate plate face 1 in this example with the lower spacing of orifice plate plate face 2 of impacting for 160mm, can Determine the cross-sectional width H=160-20=140mm of return air channel 4.
Upper and lower impact type quick freezing machine orifice plate air return structure is integrally made of stainless steel material;Stainless steel material performance is low The quick-frozen field performance of temperature is good.
By upper orifice plate perforate 3, static energy is converted into dynamic pressure can form at a high speed cryogenic high pressure air in plenum chamber Frozen food in gas shock between orifice plate on guipure, makes food cooling;The cold air of foodstuff calories is absorbed by upper punching Hitting orifice plate plate face 1, to be sucked through evaporator by evaporator fan with the return air channel 4 of the lower left and right sides of impact orifice plate plate face 2 cold But next circulation is carried out;Due to the change of air return structure, reduce the resistance in cold air cyclic process, can be in certain journey Fan energy consumption is reduced on degree.
By upper orifice plate left and right sides return air channel return air, air return structure is changed, and has saved substantial amounts of space, Improve the compactedness of instant freezer.
A kind of upper and lower impact type quick freezing machine orifice plate air return structure described in the utility model;Can effectively change up and down The air return structure of impact type quick freezing machine, solves the problems, such as upper and lower impact type quick freezing machine low space utilization, improves system entirety Space availability ratio.
