A New Level of Performance for Fresh Food Storage
Warm air rises, cool air falls.
As a refrigerator cabinet increases in size, maintaining temperature control
becomes more challenging. As a cabinet becomes taller the air has a
greater ability to settle in layers. This is called stratification. The warmer air
rises to the top of the cabinet while the cooler air settles to the bottom.
If the temperature control is at the top of the refrigerator, cooling the
cabinet enough to satisfy the thermostat can result in the bottom of the
refrigerator being too cold for the contents. A common result is frozen
lettuce. If the temperature control is in the middle of the cabinet the top of
the cabinet may be too warm for optimum shelf life of dairy products.
Temperature stratification can have a major impact on the longevity of fresh
foods. To minimize this effect the Dacor Built-in Refrigerators keep the air
moving in the fresh food section even when the temperatures are already at
their optimum. This results in temperature differences of one degree or less
throughout the fresh food compartment.
Not all fresh foods are best kept at the same temperature. Fresh cuts
of meat will keep longer at a lower temperature (31
˚
F) than vegetables
(34˚F) and citrus (38˚
F). If you set the fresh food section for the optimum
temperature for one of these product the others will not be at their best
storage temperature.
Produce crispers and meat drawers can help this situation but the Dacor
Built-in Refrigerator takes this concept a step further. Using a feature known as FoodSaver™Technology
the system allows three different temperatures to be maintained in the fresh food section. The main
section can be set for good storage of dairy and condiments as well as other foods. This temperature
can be set to whatever the customer wants, which could be approximately 37 degrees. One FoodSaver
module can be set to store the citrus at 38 degrees and the other can be set to store meats at 31
degrees. It is almost like getting three refrigerators in one cabinet. Fresh food will remain fresh longer
when stored at the right temperature.
The FoodSaver drawers each have a fan motor and temperature control incorporated into their
construction. The control can open a damper and allow the fan motor to draw cooler air from
the freezer section if needed. If the drawer needs to be warmer than the rest of the fresh food
compartment (fresh food 35 and citrus at 38) there is a small heating element that will maintain the
temperature selected by the owner.
Besides providing optimum storage temperature, the FoodSaver modules also provide better humidity
control. Conventional crisper drawers can often end up with condensation inside. This condensation
can result in excessive moisture settling on the produce and cause premature aging. The FoodSaver
modules use a space-age polymer to regulate the amount of moisture in the compartment. The pores
in this polymer increase in size when too much
moisture is present in the drawer and close
when the moisture is at the right level. This
allows excess moisture to leave the drawer and
the correct humidity level is maintained. This
eliminates the condensation problem found in
many crisper drawers.
These features and their interaction allow the
Dacor Built-in Refrigerator to keep contents
fresher for a longer period of time than
systems without these features. This allows the
customer to enjoy increased freshness in the
foods they store.
