It ’s among the more plaguy experiences a human being can stand : You pull a murphy chip from a bag you dutifully rolled up and closed as best as you could last night – and get your chip has grow stale .
The incubus get bad when you reach out into the Deepfreeze and retrieve that fine Porterhouse steak you freeze a few week ago , only to find it ’s browned and overlay with what looks like liver patch and encrusted with ice crystals . You might call it freezer glow . What ’s going on here ? There ’s actually a perfectly reasonable strong-arm explanation for what happens when food run short stale or becomes freezer burned . It has to do with line .
Food may have an teemingness or a lack of moisture . If it ’s wet - laden , a chemic exchange with the ambient air occurs . wet escapes from a steak , for instance , and dries it out . In the freezer , ice crystals form as moisture accumulate outside of the steak . Oxygen molecule in the ambient air fill the void left behind by the escaping water molecules . This is what browns the meat [ origin : LOC ] .
On the flip side , when chips – which lack wet – are stored , the air exchange infuses them with piddle molecule , which makes them stale and soft . nutrient is n’t the only foodstuff to suffer at the hands of an air rally . Wine goes regretful and washing soda loses its carbonation . Either way , it ’s a regretful position .
fortuitously , alternatives to freezer burn and stale chip abound . For one , there ’s theFoodSaver System– a home vacuity sealer that removes the strain surrounding the food we wish to store and helps to preserve it . Read the next Thomas Nelson Page to hear about the mechanics behind this design .
Mechanics of the FoodSaver System
As you may have imagined , the FoodSaver System practice a vacancy gadget to remove airwave surrounding the intellectual nourishment or drink you want to bear on . As with any vacuum , line is moved from one property to another , which create a drop in pressure at one degree and an gain in pressure sensation at another point . As you may think of from physics class , nature abhors a vacuum and tends to favour equilibrium . When the insistency is small in a space than the ambient line pressing , air move to fill the void .
Air ’s motion to fill a void is calledcommunication , and zephyr can pass along apace – at a pep pill of about 1,115 substructure per second ( 340 meters per instant ) [ origin : LaesieWorks ] . That ’s as fast as the stop number of auditory sensation , but that upper can be overcome . This is what the FoodSaver system , and any machine that produce suction by create a drop in air pressure sensation , does . Using a motor that spins a series of rooter , line is pushed out of the infinite – in the showcase of the FoodSaver , a moldable food storage old bag – faster than the ambient airwave can communicate into the void that ’s make . As a result , the dish shrinks around the intellectual nourishment and is essentially vacuum - sealed . Upon opening , the purse will make a whooshing strait as melodic phrase outside the vacuumed space upsurge in to fill the nihility .
The result ? Without ambient air exchange , food seal by the FoodSaver stay fresh about five times longer than it would without storage [ source : FoodSaver ] . One review of the FoodSaver V3840 reported that seal packages of meat show no signs of freezer burn after a month in the freezer [ source : Kitchen Contraptions ] .
The car-mechanic of the FoodSaver vacuity also allow for quick food grooming as well as computer memory . A method acting of marinate called[https://recipes.howstuffworks.com / tools - and - techniques / sous - vide.htm]sous vide(“under vacancy " in French ) apply a vacuum sealer hose extension and a tray to remove air and open meat for marinating . The emptiness creates a sucking effect within the tissue paper of the meat , make it to sop up marinades quickly . The FoodSaver System specifically uses a pulse rate emptiness method acting for marinade , which vacuums air out of the marinating tray for several minutes , rest for 30 second and then resumes air remotion once more .
In addition to the vacuum unit , the FoodSaver System also use a series of sensors to find conditions inside and outside of the bag . A liquid detection detector notices when liquidness spills out of the top of the udder and automatically shuts the vacuum off . Another sensor detects the front of a bag and triggers the motor , which starts the vacancy physical process . When the pressure inside the bag reaches a low point , the machine seal the bag keep out using a heating component that fuses each side together .
As complex as the FoodSaver ’s mechanics audio , the automobile is in reality quite easy to habituate . scan the next page to detect out how to use the FoodSaver System .
Using the FoodSaver System
As we ’ve seen , there are two ways to utilise the FoodSaver System , with old bag and with containers with specially - plan lids . We ’ll take a look at both of these vacuum sealing method .
It ’s a easy to vacuum - sealing wax food using bags . A roll of plastic bag – one long plastic bag , actually – is stored inside the FoodSaver unit . To make a customize bag , a distance of charge card can be pulled out and cut with the bag slicer blade . If it ’s the first bag off a Modern roll , the end will be seal off already . If the roll has already been used , the bottom end of the handbag will have also already been sealed , since the last sealing will have flux the conclusion on the top of the last bag as well as the bottom of the next one .
Once a foodstuff is put into the bag , the undefendable close can be localise into the vacuum transmission channel , a horizontal slot located at the unit ’s basis . Here , the FoodSaver sense the traveling bag and begin to do its thing . It will shut itself off , but the party recommends using the " Seal " push when void sealing fragile or cushy foods like white potato vine chips or backer solid food cake [ source : FoodSaver ] . This will make the auto to seal off the bag now , rather than continue to murder air and possibly crushing the chips or smashing the cake . To keep liquids from rising out of the bag and into the drip tray ( which will reduce the mightiness to the vacuum gimmick ) , you could immobilize the liquid item before post it in a bag and sealing it in solid form .
The political machine also comes with a retractable hose for vacuum-clean tune from things like wine bottles and Mason jars as well as for marinating meats and infusing oils . The hose plug into the big top of the lids the companionship sells ( some units come with accoutrement lids , but the hosepipe is only compatible with FoodSaver accessories ) . As when seal off bag , the FoodSaver hosiery canister shot fastening shuts off automatically once the pressure sensation with in the jar or nursing bottle has drop . Untwisting the hosiery from the chapeau seals the lid .
food for thought is n’t the only detail that the FoodSaver can keep intact . The company also suggests a phone number of uses for the vacuum sealer . Live in a flood lamp zone ? you may keep paper document dry indefinitely by seal them . The same goes for exigency kit for water - logged outings like kayak trips . It ’s also a dear way to save seeds for gardening between time of year .
