Chest freezers

The first arrangement for frozen foods was the ice-cream conservator, a chest-freezer type of cabinet, i.e. reach-in from the... 

As soon as the sample has been properly labeled and recorded, it should be placed in a generator-powered chest freezer located directly in the field. A flat-bed trailer can be used to transport freezers to and from the field site. Insulated boxes filled with dry-ice can be used as a substitute for freezers. However, chest freezers typically work better than dry-ice since they allow more cold air circulation around the samples, facilitating more rapid freezing.

Topcoats. For some applications such as chest freezers or vacuum cleaners, alkyds are still employed. These evolved from oil-modified types to the oil-free polyesters that have good stain resistance, high gloss, and excellent flexibility. But until recently, the thermosetting acrylic was the hallmark of appliance coatings. Acrylics exhibit excellent hardness, adhesion, chemical... 

Chest freezer and refrigerator liners have been successfully coated with powders or precoated metals to eliminate porcelain with good success. The improved impact resistance results in significant savings from shipping damage. 

Metallic (elemental) mercury is widely used in industry and is found in mercury switches and relays. These are components in chest freezers, sump pumps, irons and washing machines (they stop spin cycles or turn on lights and are used in motion-sensitive or position-sensitive safety switches). Mercury-containing relays activate airbags and anti-lock brakes. Mercury is also found in thermostats, thermometers (the small domestic variety contain ... 

Sublimation drying was performed in a custom-built dryer consisting of an eight liter vacuum chamber mounted in a commercial chest freezer, a dry ice cold trap, solvent filter, and rotary vane vacuum pump (Fig 2). This system has an ultimate vacuum pressure of approximately 2x10 Torr, and the ability to control chamber temperatures between 0 C and -25 C. This dryer allows for greater possibilities in sample size and geometry, at a lower cost than commercially available fteeze dryers. 

Period caUy, clean out freezer and dry-ice chests to remove braken ampoules and tubes of biological specimens. Use rubber gloves and respiratory protection during this cleaning. 

Freeze-Thaw Test. A limited number of mixes were subjected to a series of freeze-thaw cycles in a chest-type freezer at a rate of 6-10 cycles/day. The fundamental transverse frequency at zero cycles, rj, was measured at the beginning of each test. Additional values, rjC, were also measured at 50, 70, 110, and 150 cycles. The fundamental transverse frequency-squared vs. the number of freeze—thaw cycles is plotted in... 

When a plastic bag containing a water and ice mixture is placed in an ice chest initially at —8 °C, the temperature of the ice chest goes up. V hiy 42. The refrigerahon mechanism in a freezer with an automatic ice maker rims extensively each time ice forms from liquid water in the freezer. Why ...
