Abstract: A climate chamber for the treating of products with a conditioned gas stream includes a substantially closed compartment having two opposing lateral walls provided with one or more passages; a substantially closed channel which extends around the outside of the compartment and connects one of said lateral walls to the other of said lateral walls in order to form together with the compartment a substantially closed circuit; and a gas displacement device received in the substantially closed channel for circulating the conditioned gas stream through the circuit. The gas displacement device is provided with a reversing system configured for reversing repeatedly, in each case once a reversing time interval has elapsed, the direction in which the conditioned gas stream is circulated through the circuit. The gas stream passes through the compartment predominantly from one lateral wall to the other lateral wall.

Abstract: The invention relates to the use of a cyclone separator for separating keratin particles originating from poultry out of a gas, in particular air. The separated particles comprise down particles. The invention furthermore relates to a climate chamber for hatching eggs and/or keeping poultry. Said climate chamber comprises a substantially closed compartment having two opposite side walls provided with one or more passages; as well as a substantially closed duct which extends outside the compartment and connects one of said side walls to the other of said side walls so as to form a substantially closed circuit together with the compartment. Said climate chamber furthermore comprises a cyclone separator, the inlet of which ends in the substantially closed duct and the outlet of which ends outside the closed duct for discharging into the environment.

Abstract: Heat exchanger, in particular for use in a climate chamber, as well as to a climate chamber provided with such a heat exchanger. The heat exchanger essentially comprises a panel-shaped body (21) of heat-conducting material, which body is provided with fluid lines (22, 23, 24) for the passage of a fluid. The panel-shaped body (21) is provided with perforations (25, 26) for the passage of a gas stream (A) directed transversely to the plane of the panel-shaped body. The heat exchanger is furthermore provided with a medium, supply duct. (27) for supplying a gaseous medium to a plurality of gassing ducts (28). The gassing ducts (28) run parallel to one another along the panel-shaped body (21) and the interior of each gassing duct in each case touches a part of the panel-shaped body (21).

Abstract: This invention relates to a method for promoting growth of young chicken comprising the step; offering feed in a layered manner in subsequent order of pellet-size for adjusting the pellet-size to the size of the young chicken during a whole brooding cycle for the feed being attractive during the whole brooding cycle as perceived by the young chicken.

Abstract: A climate chamber and method for regulating a climate chamber. The climate chamber includes a temperature-controlled compartment containing a product such as hatching eggs, chickens, or chicks. The climate chamber also includes a fan which gives off heat during operation, a supply channel extending from the fan up to the compartment, and a temperature sensor provided in the supply channel. An air stream is supplied to the compartment by means of the fan via the supply channel. The temperature of the air flowing through the supply channel is detected by means of the temperature sensor. The rotational speed of the ventilator is adjusted as a function of the temperature detected by the temperature sensor for influencing the temperature of air displaced by the fan.

Abstract: The invention relates to a method for the incubation of eggs and to a device for the incubation of eggs. The incubation device includes a cabinet provided with a climate control for regulating the atmospheric humidity and temperature of the air that is to be passed through the cabinet, and at least one frame. At least one stack of trays positioned vertically above one another is arranged in the frame, each tray having a multiplicity of egg positions for receiving an egg. To turn the eggs, the trays of the stack can pivot to and fro through a defined pivot angle about a horizontal axis with respect to the frame. The vertical distance between the trays positioned above one another thereby changes. In the method, the trays are periodically pivoted through the defined pivot angle and the magnitude of the defined pivot angle is variable.
