Abstract: A method for separation of heterogeneous products included in household waste (HW) comprises separating the products in a fractionation vessel containing a liquid. The waste includes components, of which at least some are capable of floating in the liquid. The components are exposed to a first essentially horizontal force (P1) in a first direction (D1) enforced by a flow of the liquid in the fractionation vessel and to a second essentially horizontal force (P2) in a second direction (D2), which is substantially different from the first direction (D1). The combined impact of the forces (P1; P2) on the components spreads the components and leads them to at least two collection areas. Products of varying buoyancy may thus be treated separately.

Abstract: The method invented is based on sluice system according to which the product is first conveyed through a portioning device, which produces a sequence of uniform product portions divided by uniform particle free spaces, and subsequently the product portions are conveyed individually through a sluice device, which comprises at least one sluice chamber and two pressure locks of which at least one at any time secures a pressure tight barrier between the two pressure zones, and the product portions are force loaded from the first zone into a sluice chamber by means of a piston screw, the axis of which is practically in line with the axis of the sluice chamber, and the product portions are force unloaded from the sluice chamber and into the second pressure zone by means of said piston screw or a piston or by means of gas, steam or liquid supplied at a pressure higher than that of the second pressure zone.

Abstract: A free-flowing powder of coated particles is produced by means of a spray dying plant using a hot drying gas or a spray cooling plant using cold drying gas. A coating composition in liquid form is supplied to the atomizing means of the plant, and the liquid coating composition is atomized into a flow of liquid droplets, which are allowed to collide with particles of a carrier material dispersed in a transport gas. The direction and rate of flow of the transport gas are adapted to prevent contact between the drying gas and the droplets, so that the liquid coating composition, before any substantial drying thereof, will form a continuous liquid coating layer on the particles. The thus applied continuous coating layer on the particles is then allowed to at least partially dry by contact with the drying gas before withdrawal of the coated particles from the spray-drying chamber of the plant to a moving bed in the form of loose agglomerates.

Abstract: Ruminants with a fully developed rumen function are fed by a method in which the total feed is divided into two parts comprising(a) a liquid feed containing high-energy components, which feed is supplied while stimulating the ruminant to close its oesophageal groove, and(b) a solid feed containing low-energy components, which feed is supplied in such a way that the ruminant does not close its oesophageal groove,both types of feed being independently available through separate dispensing systems. One or more of the components of the liquid feed may be partially or completely hydrolyzed.A liquid feed dispensing device (an embodiment of which is shown in FIG. 1) comprises a container, metering means and outlet means for liquid feed; the outlet means (such as a teat) are located in an enclosure for ruminants at a level substantially above the level of the shoulders of the ruminants housed in the enclosure.
