Making Freeze Dried Ice Cream
Freeze dried ice cream is one of the best treats that you could have on hand in an emergency
. It is an excellent type of comfort food that can make a bad situation seem much better.
For many years it has been known as astronaut or space ice cream. These names came from the fact that the Whirlpool Corporation created this treat for the NASA astronauts going on the Apollo missions.
However, the 1968 Apollo 7 mission was the only NASA mission in which the ice cream was actually sent into outer space. The only explanation given for this was that it was not very popular, even though it was created on request.
In addition, the Skylab was equipped with a refrigerator that could store real thing, which is still a special treat for Space Shuttle and International Space Station astronauts.
The process of freeze drying is also known as lyophilization. This process removes the water, through the lowering of the air pressure to a point where the ice changes directly from a solid to a gas.
It is then put into a vacuum chamber where it is frozen until the water crystallizes. Then, the air pressure is lowered which creates a partial vacuum.
This process forces the air out of the chamber. Then, the substance is heated, which vaporizes the ice. A freezing coil traps the vaporized water.
This process takes several hours. In the end, freeze dried ice cream is basically a chunk of dehydrated ice cream.
This dehydrated chunk does not need to be refrigerated and it is ready to eat at all times, making it ideal for space travel. This treat can often be found in science museum gift shops along with other unique foods.
Pizza and various kinds of fruit are also common freeze dried foods. These foods can also be obtained through mail-order.
However, the ice cream is by far the top seller at many of these gift shops. It's very sweet when it comes to taste and seems to melt in your mouth.
Occasionally it becomes sticky and small chunks of ice cream stick to the gums. This happens because all of the moisture is removed.
Another characteristic is that it crumbles if it is put under too much pressure, one again because the water has been removed. It is packaged in an airtight container resulting in a dry, lightweight product.
Today, it is very popular all over the world. It is possible to make this ice cream yourself as well.
In order to make your own freeze dried ice cream you will need a scooper, plastic wrap, a freezer that can reach -40 degrees Celsius, a foil pouch, vacuum, and a dehydration sealer machine.
First you will need to make ice cream by following your favorite recipe. Another option is to purchase it already made and use that instead.
Several flavors can even be included in one package of freeze dried ice cream. Scoop out one serving of ice cream onto the plastic wrap.
Then, put the scoop into a regular freezer. When it is extremely hard, take it out of the freezer.
Remove the plastic wrap from the outside of the ice cream. Then put it in a foil pouch and place the pouch in a dehydration sealer machine.
Then, dehydrate the serving of ice cream. Next, put the foil pouch in a freezer that reaches -40 degrees Celsius.
Leave it in the freezer overnight. The process may need to be repeated several times before it is done.
Make sure that you follow the instructions on the dehydration sealer machine. You do not want to make any mistakes.
However, it will be a very tasty treat when it is done. This homemade treat should still be stored in the freezer, but it will last a very long time.
This freeze dried treat will become more available in the next few years to the public as well. This treat is going to become even more popular.
