Description
Technical field
The invention belongs to agricultural product processing machinery technology field.
Background technology
Nitrogen is basic surrounding material, it is a kind of colorless and odorless, the inactive inert gas of chemical property, accounts for 78% of earth atmosphere, can not leave any chemical residue when gaseous nitrogen is used for antistaling process, and it is low to have operating cost, the fireballing clear superiority of aerogenesis.
Traditional method for refreshing agricultural products adopts chemical method, and as utilized antistaling agent process oranges and tangerines, potato etc., but antistaling agent can remain on agricultural product, works the mischief to the health of eater, causes food poisoning time serious; Therefore, it is fresh-keeping that present a lot of agricultural product all adopt physics mode to carry out, such as on agricultural product, wrap up preservative film, but this process fresh keeping time length is not as good as Chemical Preservative Method of Fruits, therefore, many times now, be all adopt gaseous nitrogen to carry out fresh-keeping to agricultural product, gaseous nitrogen can not leave any chemical residue when being used for antistaling process, and lower compared to preservative film cost.
The fresh-keeping mode of current gaseous nitrogen is all adopt food-grade nitrogen charger, this nitrogen charger comprises vavuum pump, nitrogen gas generator, appendix, valve, vavuum pump first vacuumizes agricultural products fresh-keeping bag, then the valve open of nitrogen gas generator, is filled with by nitrogen in agricultural products fresh-keeping bag.The shortcoming of this mode is: valve needs first to insert (from sack insertion) in agricultural products fresh-keeping bag, vacuumize with inflated with nitrogen is all operated by valve, and the excesssive gap between valve and agricultural products fresh-keeping bag can not be fitted completely, then can cause vacuumizing and leak with the easy of inflated with nitrogen, fresh-keeping effect is not good.
Summary of the invention
The invention is intended to provide a kind of valve can be fitted tightly with agricultural products fresh-keeping bag, prevent from vacuumizing and fill in nitrogen process the nitrogen preservation method occurring to leak.
This programme nitrogen preservation method, uses nitrogen preservation device, comprises the steps:
1. the freshness protection package that agricultural product are housed is placed on the 3rd fixture block, the 4th fixture block, the dual-side of freshness protection package is contacted with the corrugated teeth of the 3rd fixture block, the 4th fixture block respectively;
2. feeding motor drives valve to insert in the sack of freshness protection package;
3. electric rotating machine starts, and the first belt wheel rotates, and the first fixture block connected with the first belt wheel wheel face bias, the second fixture block relatively move to and contact; First belt wheel drives the second belt wheel to rotate by V belt, and the 3rd fixture block connected with the second belt wheel wheel face bias, the 4th fixture block relatively move to and contact;
4. lift cylinder and electric rotating machine start simultaneously, and lifter plate drives the first fixture block, the second fixture block moves down; The ripple flank of tooth of the first fixture block and the 3rd fixture block is by the side compressing of above-mentioned freshness protection package, and the ripple flank of tooth of the second fixture block and the 4th fixture block is by another side compressing of freshness protection package;
Form the through hole fitted with valve outer wall after the cambered surface split of 5. the first fixture block, the second fixture block, the 3rd fixture block, the 4th fixture block, make freshness protection package be adjacent to completely on valve outer wall;
6. open the vacuum valve on vavuum pump, the air in freshness protection package is extracted out by valve, and then vacuum valve cuts out; Valve open on nitrogen gas generator, valve is filled with nitrogen in freshness protection package.
Beneficial effect: step 1. in first place freshness protection package, 2. valve inserts in the sack of freshness protection package by step, step 3. by electric rotating machine drive upper first fixture block, the second fixture block relative movement, the 3rd fixture block, the 4th fixture block relative movement; Meanwhile, step 4. middle lift cylinder starts, the ripple flank of tooth of the first fixture block and the 3rd fixture block is by the side compressing of above-mentioned freshness protection package, the ripple flank of tooth of the second fixture block and the 4th fixture block is by another side compressing of freshness protection package, prevent freshness protection package from moving, final four fixture block splits make freshness protection package be pressed on valve outer wall, again freshness protection package vacuumized and fill nitrogen process, the present invention can prevent valve carrying out leaking when vacuumizing or fill nitrogen, can obtain and fill nitrogen effect preferably, through the agricultural products fresh-keeping better effects if of this nitrogen preservation method process.
