Once you have bottled and/or packaged your vegetables they will have to be stored in a cold environment that is
below their freezing point and at a low humidity level, Cardboard Freezer Boxes A cold environment slows down the
natural deterioration of vegetable matter that occurs. Most vegetables that are placed into a cold environment will go
into a type of dormant state.
Obviously a cold storage room is the most economical method. It uses the winter temperatures to keep foods cold.
Unfortunately its downside is that the temperature cannot be regulated. If the outside temperature changes so does
the temperature inside the cold storage room. Also few modern homes have a cold storage room. It is considered
unnecessary in today's fast paced society.
For those without the basement cold storage room an alternative is the household freezer. Many people use a small
chest freezer for this purpose. Chest freezers seem to be the answer for many gardeners. An upright freezer will also
work but they are not as efficient (or as cold) as the chest variety. Also the small chest freezer is generally less
expensive than an upright of the same size.
Basically freezer blocking is filling up the unused space inside the freezer. The theory is ... the less air inside the
freezer the less electricity will be required to freeze the food. Anything that lowers the internal volume of the freezer .

2. To do this cardboard boxes called "blockers" are placed inside the freezer. These boxes are filled with insulation. Any
form of insulation will work, but basic household wall insulation (fibreglass) is most commonly used. It is both
inexpensive and easily obtained. An alternative are the insulating peanuts used for shipping and packaging. Others
suggest filling the boxes with old newspapers. This would work but the insulation value would be far less than the
fibreglass method. Also the newspaper would pick up moisture and become extremely heavy to lift.
If the freezer is only half full then place the boxes either at the bottom of the freezer or all to one side. This way you
have easier access to the food during the winter. Placing the boxes on top will be frustrating because you will have to
remove them every time you want to get to the food.
This is not true freezer blocking. Rather it is a method called heat sinking. Containers of water added to the freezer
will themselves freeze into blocks of ice. Every time the freezer shuts off the cold stored inside the ice blocks will help
keep the food frozen. The ice should slow down the natural heat transfer between the freezer walls and the food. The
colder the freezer interior the less the cold control will turn on the compressor.
