GastroNorm 1/3 drain trays are essential elements in any kitchen where food preservation takes place. They are used in the preservation of foods that release juices, reducing the amount of losses due to spoilage. Fresh meat and fish release a liquid called exudate. This exudate contains nutrients and water that can encourage the proliferation of bacteria, with a resulting potential health hazard. Correct preservation of this type of food requires the use of drain trays that separate the exudate from the food. The drain trays used for this purpose must be high enough to avoid the exudate flowing over the drain trays and their design must avoid sharp edges, corners and nooks where the exudate can accumulate. The drain tray is placed in the bottom of the container and encourage drainage to the bottom, thus avoiding contact between the liquid and the food and reducing the risk of proliferation of bacteria. Araven has drain trays that adapt to its food containers (in GastroNorm sizes as well as other sizes) designed to evacuate exudates, and thus maintain food quality.
