The following was posted to the freenrg list and has correlations with =
the cooling effects claimed in some free energy devices based on
magneto-calorics. The phenomen of using a swept magnetic field to
transport heat from a central core to the outside to be dissipated was
first explained to me by Jack Veach (Bocephus to those who know
him..<g>). Check it out;
New Fast Freezing System
IB Industries (Chiba Prefecture, Japan) has developed an instant
freezing
system said to be capable of maintaining the flavor and freshness of
foods
that ordinarily freeze poorly.
Conventional freezers slowly freeze an object from the outside inward.
During this time, quality deterioration, such as cracking and shrinkage,
often occur. The new system-to be marketed under the brand name "Spiral
Dielectric Freezer"-is said to avoid this by using temperatures of -60=B0=
C
to
rapidly freeze items.
The food is first placed within a special magnetic field. A weak current
is
generated within the food causing the internal water molecules vibrate,
preventing them from freezing first. When the food is then subjected to
the -60=B0C, both the principal ingredients and the moisture are frozen
simultaneously. According to IB Industries, this prevents drying and
deterioration, and preserves both aroma and flavor.
The company has until now primarily marketed its freezer equipment to
small
and mid-size confectionery manufacturers and bakeries. With the
tightening
of HACCP regulations governing the storage and serving of food, the
company
believes the product will generate much interest across the food product
manufacturing and distribution sector.
