This invention relates to the composition of a chitosan coated paper wherein the chitosan may be derived from a variety of sources. Methods of using chitosan as a surface coating or pulp additive to tune the properties of paper and paperboard products are also described. The chitosan applied is a bio-based and environmentally friendly barrier coating and/or additive material for the manufacture of functional paper and paperboard products, specifically as evaporative cooling media requiring wet strength and structural integrity, wicking, and moisture resistance as an alternative to conventional phenolic-based resins. The solid-state fermentation method to produce chitosan and its derivatives offer renewable bio-based materials towards the manufacture of functional paper products that are eco-friendly but also offer uncompromized performance levels.

Heat exchange apparatus comprises a plurality of thermally conductive, moisture impervious sheets. Each sheet comprises a plurality of corrugations. The plurality of sheets are disposed in a stack such that each alternate sheet has its corrugations affixed to and disposed at an angle to the corrugations of an adjacent sheet to provide a plurality of separate flow pathways. The plurality of separate flow pathways comprises first predetermined pathways and second predetermined pathways. The stack of sheets have first end portions disposed to provide a first inlets and a first outlets for the first predetermined pathways and second end portions to provide second inlets and second outlets for the second predetermined pathways. The corrugations forming the second predetermined pathways comprise a wettable surface. The first predetermined pathways are adapted for a first fluid flow and the second predetermined pathways are adapted for a countercurrent second fluid flow.

A staged dry out process and control system for an evaporative media cooling system having a plurality of media stages that are selectively activated and deactivated by a control system is disclosed. The staged dry out process ensures that wet media stages are appropriately dried with minimal disruption to the staging strategy implemented by the control system. In one aspect, the staged dry out process monitors deactivated media stages to determine if the media stages reach a dry state before being activated. In another aspect, the staged dry out process locks out a media stage that has been in a wet state beyond a predetermined maximum time limit until the media stage attains a dry state. With this strategy the cooling system can operate without being required to completely shut down for a drying process.

A device for producing and treating a gas stream is provided that includes an enclosure, of which the lower part is submerged in a liquid supply open at the top and includes at least one liquid intake opening. The submerged lower part of the enclosure contains a volume of this liquid and at least one opening for discharging a gas stream, positioned above the surface of the volume of liquid contained in the enclosure. The device further provides for injecting a gas stream including at least one injection conduit and extends in the upper part inside the enclosure outside the volume of liquid. During operation of the device an incoming gas stream is introduced to create an outgoing gas stream, treated by direct contact with said volume of liquid that is discharged outside the enclosure. A facility inclusive of the device and method of operation are also provided.

A pre-chill system for reducing the temperature of air entering a cooling system includes a wicking material sheet and a series of frame segments. The frame segments are operable to secure the wicking material sheet to an outer casing of the cooling system in a path along which air enters the cooling system, each of the series of frame segments including one or more magnets magnetically attachable to the cooling system. A misting system is capable of directing moisture adjacent an outer face of the wicking material sheet. The frame segments are magnetically attachable to the outer casing of the cooling system over the wicking material sheet so as to retain the wicking material sheet against the outer casing with the wicking material sheet held between the frame segments and the outer casing.

A heat exchange matrix includes a plurality of generally planar foils including a water retaining material, arranged in spaced, substantially parallel relationship. Each foil defines a main plane having a flow direction and a transverse direction and the foils include strips that extend a strip length in the transverse direction and are separated from each neighboring strip in the flow direction and each strip is offset from the main plane by a distance that is different from that of its neighbor. The matrix may be provided in a flow channel for air to be humidified and cooled.
摘要:
A method for introducing a vaporous heat carrier into a liquid product, in particular a food product or beverage, and more particularly viscous products, for example desserts, sauces or concentrates, includes using the carrier to heat the product to form a germ-free product. An injector for carrying out the method is also described. A reduction in the heat transfer capacity of the injector is prevented over the entire production time. This is achieved in that three physical measurement variables which can be detected during operation of the injector are used as indicators of the formation of product deposits. At least one of said three physical measurement variables is detected, and depending on these variables, an automatically controlled axial movement of the displacement body is carried out such that the heat transfer capacity from the vaporous heat carrier into the liquid product remains the same.
