Abstract
The utility model discloses a compound freshness protection paper, which comprises an upper unventilated paper, a lower unventilated paper and a plurality of small empty cavities isolated with each other between the layers. A solid preservative is filled into the empty cavity. A plurality of micro holes are arranged in the empty cavity part of the upper layer paper. The outer surface of the upper layer paper is pasted with a foam net. The compound freshness protection paper enables no direct contact between the fruit and the fresh gas. The air stream spreads smoothly and uniformly, thereby avoiding contacting pollution of preservative to fruit and having shock absorption action. The utility model is applicable to fruit transportation and freshness protection, in particular to grapy.
Description
The utility model relates to the preserving fruit and vegetable utilizing field, relates in particular to the transportation fresh-retaining of grape.
Along with the raising of quality of life, people are to the season of gourd, fruit and vegetable and newly rarely had higher consumption demand, and preservation technique provides possibility for satisfying this demand, makes people can taste nonlocal fruit and anti-season fruits and vegetables easily.At present fresh-keeping in the fruits and vegetables long-distance transport mainly contains methods such as the fresh-keeping and tin foil of airtight fumigation is fresh-keeping.Characteristics such as wherein tin foil is fresh-keeping need not other other facility because it is simple to operate, with low cost are used more extensive, especially all the more so aspect grape fresh-keeping.The patent No. is that the Chinese utility model patent of 00237059X discloses a kind of composite fresh-keeping paper, comprise, descend bag shape cavity separate between two-layer air-locked paper and paper, fill solid preservative in the cavity, cavity paper wall offers aperture, this composite fresh-keeping paper making technology is simple, cost is low, can be by the speed that antistaling agent discharges of how much regulating of little hole number, can realize slowly-releasing, make fresh keeping time and effect more satisfactory, but, make its aperture directly contact with fruit because this composite fresh-keeping paper is overlying on the fruit, influenced the unimpeded of antistaling agent gas and flowed, and made the fruit at aperture place be subjected to the pollution of antistaling agent.
Goal of the invention of the present utility model is to overcome above-mentioned deficiency, provides a kind of and can effectively realize the antistaling agent slowly-releasing, the composite fresh-keeping paper that can avoid antistaling agent and fruit directly to contact again.
Goal of the invention of the present utility model is to be realized by following scheme: composite fresh-keeping paper, comprise the bonding upper and lower two-layer air-locked paper and the areola of the some mutual isolation of interlayer thereof, be filled with solid preservative in the cavity, it is some that described upper paper offers micropore at re-entrant portion, at the bonding one deck lightweight of described upper paper outer surface grid material.Described lightweight grid material is preferably foam screen.
After adopting as above design, quantity and distribution by the control micropore, can realize slowly discharging in an orderly manner of antistaling agent gas, again since on the paper of upper strata compound lightweight grid material, make fruit directly not contact with tin foil, the antistaling agent air-flow is unimpeded and avoided contact stain, also has certain bumper and absorbing shock effect.
Further elaborate below in conjunction with the 26S Proteasome Structure and Function of drawings and Examples this composite fresh-keeping paper.
Fig. 1 is this composite fresh-keeping paper schematic diagram.
Fig. 2 is the side sectional view of the cavity 8 of composite fresh-keeping paper shown in Figure 1.
As Fig. 1 and Fig. 2, a kind of composite fresh-keeping paper, comprise the bonding upper and lower two-layer air-locked paper 2,3 and the areola 8 of the some mutual isolation of interlayer thereof, be filled with solid preservative 4 in the cavity 8, described upper paper 2 offers micropore 7 at cavity 8 positions some, at the bonding one deck lightweight of described upper paper 2 outer surfaces grid material 1, lightweight grid material 1 is a foam screen in the present embodiment.
When vanning or basket, with this composite fresh-keeping paper foam screen 1 towards fruit, the volatilization gas of antistaling agent 4 flows out from micropore 7, because the buffer action of foam screen 1, air-flow is unobstructed, makes antistaling agent 4 gases not be obstructed and evenly scatters, and fruit does not directly contact pore, avoided the pollution of 4 pairs of fruits of antistaling agent, foam screen 1 also has cushioning effect in the long-distance transport, has alleviated because the mechanical damage of winnowing with a dustpan and cause in the mountain peak to fruit.
Foam screen 1 can be other lightweight grid material in the present embodiment.
Claims (2)
1, a kind of composite fresh-keeping paper, the areola (8) that comprises bonding upper and lower two-layer air-locked paper (2), (3) and the some mutual isolation of interlayer thereof, be filled with solid preservative (4) in the cavity (8), described upper paper (2) offers micropore (7) at cavity (8) position some, it is characterized in that: at described upper paper (2) outer surface bonding one deck lightweight grid material (1).
2, tin foil as claimed in claim 1 is characterized in that described lightweight grid material (1) is a foam screen.
