摘要:
A foodstuff air treatment device includes a housing (1) with an elongated trough (11) for receiving the foodstuffs to be treated. The trough extends through the housing and includes a foraminated bottom (15), a first side wall (17), and a second side wall (15). A heat exchanger (12) is disposed in the housing, and a fan assembly (13) is also disposed within the housing for producing an air flow that circulates through the heat exchanger, up through the trough, and back to the heat exchanger. One side wall (17) of the trough is adjustable, laterally to the length of the trough, for changing the width of the trough.
摘要:
An air treatment apparatus comprises a housing (1) which has a casing made up of three elements (2-4), which are pivotable in relation to each other about shafts (9, 15) parallel to a longitudinal direction of an elongate trough provided in the housing. A lower element (2) supports the elongate trough, a heat-exchanging battery and a fan assembly. A rear element (3) forms a first side wall and is pivotable about an upper edge, so as to provide access to the heat-exchanging battery and the fan assembly from outside. An upper element (4) forms at least part of a second side wall and is pivotable in relation to the lower element, so as to provide access to the elongate trough from outside.

An air treatment plant for foodstuffs includes an elongate trough (29) for the foodstuffs, a heat exchanger (35), a fan assembly (39) for circulating air on a path through the heat exchanger, through the trough, and back through the heat exchanger, a housing (1) having a housing bottom (7), and side walls (2, 3) with modular units (11) extending transversely to the trough. Each one of the modular unite includes an insulation layer (19), a water-impermeable inner layer (20), and two submodules (12, 13). Each has a respective submodule bottom with a respective bottom panel (15, 16) and a side-wall panel (17, 18) forming part of side walls (2, 3). One or more elongate, separate second bottom panels (14) interconnect the first bottom panels (15, 16) of the two submodules. Upper sides of the bottom panels (15, 16) of the submodules slope downwards toward at least one of the second bottom panels (14). One of the second bottom panels has a second upper side sloping downwards towards a one of two end walls (4, 5) of the housing.

摘要:
An air treatment plant, e.g. a freezing plant for foodstuffs, comprises a housing (1), an elongate trough (12) provided therein for receiving the foodstuff to be treated, a heat exchanger (13), and a fan assembly (14) for producing an air flow circulating through the heat exchanger, up through the trough and back to the heat exchanger. The bottom of the trough comprises a foraminated conveyor belt (16). The conveyor belt (16) is driven by an electric motor having a control unit for at least periodically driving the conveyor belt in a direction opposite to the throughfeed direction of the foodstuff in the trough (12).
摘要:
In a method for preventing bacterial growth in a refrigerating or freezing plant for food, the plant (1 ) includes a substantially closed housing (2) and, arranged therein, a device (3) for refrigerating food in this housing, and has an operating cycle including a work period during which the refrigerating device (3) is active, and a rest period during which the refrigerating device (3) is inactive and the plant can be cleaned. The cleaning includes raising the temperature in the plant above a temperature requisite for killing bacteria. Furthermore, the air pressure in the plant is maintained higher than the ambient pressure, at least during the entire rest period, by supplying air free from bacteria. The plant (1) includes heaters for raising the temperature therein during a rest period above a temperature requisite for killing bacteria, and air supply devices (7, 8) for supplying the air free from bacteria.
