It is higher.Controlled atmosphere technology refers to atmosphere (the gas componant ratio by adjusting closing space residing for storage thing in general manner
Example or gas pressure) mode extend the technology of shelf life of food products, its general principle is：In certain closing space
It is interior, the atmosphere different from normal air constituent is obtained by various regulative modes, to suppress to cause storage thing (usually to eat
Material) putrid and deteriorated physiological and biochemical procedure and microorganism activity.Especially, in this application, the controlled atmosphere discussed will
Specifically designed in the controlled atmosphere technology that gas component ratio is adjusted.
Those skilled in the art know that normal air constituent includes and (presses volume percentage, hereafter together)：About 78%
Nitrogen, about 21% oxygen, about 0.939% rare gas (helium, neon, argon, krypton, xenon, radon), 0.031% carbon dioxide, with
And 0.03% other gases and impurity (for example, ozone, nitric oxide, nitrogen dioxide, vapor etc..In controlled atmosphere field,
Generally reduce by the way of oxygen content to obtain the fresh-keeping gas atmosphere of rich nitrogen oxygen deprivation using being filled with nitrogen-rich gas to closing space
Enclose.Here, those skilled in the art know, nitrogen-rich gas refer to that nitrogen content exceedes nitrogen content in above-mentioned normal air

In addition, the said structure of support frame 32 ensure that controlled atmosphere film 31 results in enough supports, collected even in oxygen rich gas
Also preferable flatness can be remained in the case that chamber internal negative pressure is larger, it is ensured that the use longevity of controlled atmosphere membrane module 30
Life.
In a further embodiment, aforesaid plurality of first floor may include：Multiple first narrow rib plates and multiple first wide
Floor.Plurality of first wide floor is arranged at intervals, and multiple first narrow rib plates are set between two neighboring first wide floor.It is foregoing
Multiple second floors may include：Multiple second narrow rib plates and multiple second wide floors, the multiple second wide floors are arranged at intervals, adjacent
Multiple second narrow rib plates are set between two the second wide floors.It should be readily apparent to one skilled in the art that " width " " narrow " herein is
Comparatively.
In certain embodiments, each first wide floor caves inward to be formed from its side surface for forming first surface
First groove；Each second wide floor caves inward to form second groove from its side surface for forming second surface, so that
On the premise of the thickness very little (volume very little in other words) for ensureing support frame 32, the connection of its inner mesh structure is improved
Property.
In a further embodiment, the part surface away from first surface of each first wide floor prolongs towards the second floor
Extend concordant with second surface, and cave inward to form the 3rd groove from the part surface concordant with second surface；3rd ditch
Groove connects to form crisscross grooves with the position that second groove is intersected.At least one second wide rib in aforesaid plurality of second wide floor
The part surface away from second surface of plate extends to concordant with first surface and certainly concordant with first surface towards the first floor
The part surface caves inward to form the 4th groove；Wherein the 4th groove connects to form cross with the position that first groove is intersected
Groove.In some embodiments of the present utility model, for the ease of the flowing of air-flow, as shown in Figure 10, the interior table of ceiling plate portion 26
Face can extend downwardly out multiple wind-guiding floors, every to guide the air-flow from blower fan 60 to flow through controlled atmosphere membrane module 30 in accommodating chamber
The outer surface away from oxygen rich gas collecting chamber of individual controlled atmosphere film 31.Multiple wind-guiding floors are divided into two groups, including first group is led
Wind rib plate and first group of wind-guiding floor are on the symmetrically arranged second group of wind-guiding floor of a plane.Every group of wind-guiding floor includes the
One wind-guiding floor, at least one second wind-guiding floor and at least one the 3rd wind-guiding floor.First wind-guiding floor is from centrifugal blower
Air outlet at extend to the side of accommodating chamber, and extend to a lateral outer side of controlled atmosphere membrane module 30.Each second wind-guiding
Floor is arranged between two the first wind-guiding floors, and between controlled atmosphere membrane module 30 and centrifugal blower.Each 3rd wind-guiding
Floor is located at a lateral outer side of controlled atmosphere membrane module 30, to guide air-flow to enter the both lateral sides of air-flow from controlled atmosphere membrane module 30
Enter the gap between controlled atmosphere membrane module 30 and the basal surface or top surface of accommodating chamber.
So far, although those skilled in the art will appreciate that herein it is detailed have shown and described it is of the present utility model many
Individual exemplary embodiment, still, still can be public according to the utility model in the case where not departing from the utility model spirit and scope
The content opened directly determines or derived many other variations or modifications for meeting the utility model principle.Therefore, this practicality is new
The scope of type is understood that and regarded as to cover other all these variations or modifications.
