APPARATUS AND METHOD FOR PRESERVING, PROTECTING, OR ENHANCING ITEMS INCLUDING SOLIDS OR LIQUIDS
An apparatus and method for preserving, protecting or enhancing one or more items such as solids or liquids. The apparatus includes a housing and a nitrogen generator. A nitrogen generator generates a nitrogen rich gas and supplies the nitrogen gas to the housing, which displaces the oxygen inside the housing to preserve the item or items enclosed by the housing.
1 : An item preservation, protection or enhancement apparatus comprising:
a housing including an item storing compartment configured to hold an item;
an automatic nitrogen generator configured to generate nitrogen rich gas from air;
a fluid communication line connecting the item storing compartment with the nitrogen generator and configured to communicate nitrogen rich gas generated by the nitrogen generator to the item storing compartment;
at least one sensor associated with the item storing compartment, wherein after a designated signal from the sensor, the nitrogen generator causes said generated nitrogen rich gas to be communicated to the item storing compartment; and
an air exhaust device configured to exhaust gas from the item storing compartment.
2 : The apparatus of claim 1 , wherein the housing includes a mechanism storing compartment.
3 : The apparatus of claim 2 , wherein the mechanism storing compartment supports the nitrogen generator.
4 : The apparatus of claim 1 , wherein the item storing compartment includes a closable member.
5 : The apparatus of claim 1 , wherein the nitrogen generator includes an air compressor.
6 : The apparatus of claim 5 , wherein the nitrogen generator includes an air dryer fluidly connected to the air compressor.
7 : The apparatus of claim 6 , wherein the nitrogen generator includes an oxygen adsorbing carbon molecular sieve fluidly connected to the air dryer.
8 : The apparatus of claim 7 , wherein the nitrogen generator includes a nitrogen storage tank fluidly connected to the carbon molecular sieve.
9 : The apparatus of claim 8 , wherein the nitrogen generator includes a pressure retaining valve connected to the carbon molecular sieve, said pressure retaining valve set to open at a preset pressure.
10 : The apparatus of claim 5 , wherein the nitrogen generator includes at least one relay switch connected to the air compressor.
11 : The apparatus of claim 1 , wherein the nitrogen generator includes a manifold having an inlet and at least one outlet.
12 : The apparatus of claim 1 , wherein the nitrogen generator includes an electronic controller configured to receive signals from said at least one sensor.
13 : The apparatus of claim 1 , wherein the nitrogen generator includes:
(a) an air compressor;
(b) an air dryer fluidly connected to the air compressor;
(c) an oxygen adsorbing carbon molecular sieve fluidly connected to the air dryer to separate nitrogen from the air;
(d) a nitrogen storage tank fluidly connected to the carbon molecular sieve to store the nitrogen separated from the air;
(e) a pressure retaining valve connected to the carbon molecular sieve, said pressure retaining valve set to open at a preset pressure;
(f) a relay switch connected to the air compressor; and
(g) an electronic controller connected to the air compressor.
14 : The apparatus of claim 1 , which includes a plurality of item storing compartments, a plurality of fluid communication lines connecting the item storing compartments with the nitrogen generator and configured to communicate nitrogen generated by the nitrogen generator to the item storing compartments, and a plurality of sensors, each associated with one of the item storing compartments, wherein for each sensor, after a designated signal from said sensor, the nitrogen generator causes said generated nitrogen rich gas to be communicated to the item storing compartment associated with sensor.
15 : The apparatus of claim 1 , which includes a condition controller configured to control a designated condition besides the amount of nitrogen in the item storing compartment.
16 : The apparatus of claim 1 , wherein the item storing compartment is configured to hold a solid.
17 : The apparatus of claim 1 , wherein the item storing compartment is configured to hold a liquid.
18 : A method of preserving, protecting or enhancing an item comprising:
placing the item in an item storing compartment;
generating nitrogen rich gas;
after a designated signal from a sensor associated with the item storing compartment, communicating the generated nitrogen rich gas into the item storing compartment through a fluid communication line connecting the item storing compartment with the nitrogen generator; and
exhausting gas from the item storing compartment.
19 : The method of claim 18 , wherein generating the nitrogen rich gas includes:
(a) compressing air;
(b) drying the compressed air;
(c) directing the dried compressed air through an oxygen adsorbing carbon molecular sieve fluidly to separate nitrogen from the air; and
(d) storing the nitrogen separated from the air.
20 : The method of claim 18 , which includes controlling a designated condition besides the amount of nitrogen rich gas in the item storing compartment.
21 : The method of claim 18 , wherein the item is a solid.
22 : The method of claim 18 , wherein the item is a liquid.
