Novel, Safe and Efficient Thermal Transfer Media for Processing of Food and Drink Products

Номер: US20130078349A1
Автор: Paul Bernard Newman
Принадлежит: Paul Bernard Newman

A family of novel thermal processing and transfer media has been designed for optimized food and drink processing. These media composed solely of compounds approved to contact food, are essentially free of water, do not change state at any point in the process, remain corrosion-free throughout their useable life. While in combination with novel processing apparatus and methodologies, food and drink products requiring any heating, holding or cooling can be processed within the same equipment configurations essentially with no/minimal need for additional pressurization, the use of unheated modified atmospheres, in conjunction with these novel media, can be used to change or control the atmospheres within containers, especially polymer based containers, at specific locations within the processing cycle. It further relates to using different media compositions for each processing stage modified to optimize the thermal conductivity and thermal diffusivity properties of the foodstuff being processed, minimizing costs and maximizing quality.

Surface treatment of beverage containers to keep the beverage cool

Номер: US20140026595A1
Автор: Barbara Hildegard Pause
Принадлежит: Individual

The invention pertains to a method suitable to reduce the heat transfer into a beverage container in order to keep the beverage cool over an extended period of time after taken from the refrigerator. The method is based on a surface treatment of the beverage container which comprises a binder in which phase change material is incorporated. By absorbing latent heat without a temperature increase, the phase change material creates a thermal barrier against heat penetration. The binder with the phase change material contained wherein is applied to the surface of the beverage container, for instance, by spray coating. The coating layer covers most of the container's surface. A second coating layer which does not contain phase change material is applied on top of the first coating layer in order to provide protection against mechanical stress during high speed filling and packaging.

The present invention relates to a nanoencapsulated temperature regulating agent which presents a nanoencapsulated temperature regulating agent (ARTN/NTRA) that aggregates, in a same nanostructure, an organic material capable of undergoing melting by absorbing heat, or solidification by releasing heat, and IR radiation screening nanoparticles, a colloidal oxide capable of reflecting the infrared radiation which causes surfaces exposed to a heat source to heat up. The NTRA produced may be either in the form of a colloidal dispersion in an aqueous medium or in the form of nanoparticles, if the aqueous dispersion of the NTRAs is subjected to any drying process such as spray-drying, fluidized-bed drying, filtration, lyophilization, centrifugation, inter alia. The association of temperature regulating mechanisms and the fact that the NTRA is on a nanometric scale imparts greater efficiency for heat transfer processes and surface-covering power, guaranteeing greater reflection of infrared radiation. By virtue of its versatility and different forms of presentation, this NTRA makes it possible to obtain different types of products for use in the cosmetics, pharmaceuticals, medical equipment, prostheses, textiles, paints, coatings, composites, packaging, civil engineering, electrical or electronic equipment, automobile and paper-making industries. 1.

The present invention describes an approach to the design of temperature regulation systems combining, in a single structure, a heat absorption or release system by fusion or solidification of a particular material and also a particulate oxide that contributes to reflecting infrared radiation. The production of the thermofunctional nanostructure comprises six successive processing steps: a) pre-emulsifying the organic material and dispersing the colloidal oxide nanoparticles in an aqueous phase, the pre-emulsion; b) reducing droplet size in the pre-emulsion by high-pressure homogenisation; c) adsorbing the monomer in the resultant emulsion; d) polymerising and forming thermoftmctional nanostructures; e) cooling the nanosuspension containing the thermofunctional structures; and optionally f) drying the product. The resultant thermofunctional nanostructure can be in the form of a colloidal dispersion in an aqueous medium or of a nanoparticle powder, if the aqueous nanostructure dispersion is subjected to a drying process. This thermofunctional nanostructure can be applied to obtain products in the fields of cosmetics, pharmaceuticals, medical equipment, prostheses, textiles, paints, coatings, composites, packaging, civil engineering, electrical or electronic equipment, the automobile and paper industries.

In the latent heat storage body () according to the present invention, the surface of a core particle () composed of a latent heat storage material of a metal or an alloy is coated with an oxidized film of a compositional element of the core particle (). Hence, the step of separately fabricating the core particle and the oxidized film () corresponding to a shell accommodating the core particle and accommodating the core particle inside the shell becomes unnecessary. Further since the core particle exhibits no expansion when transforming from a solid phase to a liquid phase, the component of the melted latent heat storage material stays inside the space covered with the oxidized film and the oxidized film is never damaged. Further, the oxidized film () can be made chemically stable. 1. A latent heat storage body microcapsule , comprising:a core particle comprising a latent heat storage material of an alloy; anda double film, with which a surface of the core particle is coated, and comprising a compact first oxidized film of a compositional element of the core particle, and a second oxidized film, provided on an outer surface of the compact first oxidized film, of a compositional element of the core particle,{'sub': A', 'B', 'A', 'B, 'sup': 0', '0', '0', '0, 'wherein the alloy of the core particle is an A-B alloy of at least one alloy component A selected from the following group A with at least one alloy component B selected from the following group B; and a standard free energy (ΔG) of oxide formation of the alloy component A and a standard free energy (ΔG) of oxide formation of the alloy component B satisfy a relationship of ΔG≧ΔGgroup A: Ca, Si, Bi, Mg, Sb, In, Sn, Al, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, Pd, Ag, Au and Pb; andgroup B: Al, Cr, Mn, Si, Mg, Co and Ni.2.

Microcapsules adapted to rupture in a magnetic field to enable easy removal of one substrate from another for enhanced reworkability

Номер: US20160052239A1

An enhanced thermal interface material (TIM) gap filler for filling a gap between two substrates (e.g., between a coldplate and an electronics module) includes microcapsules adapted to rupture in a magnetic field. The microcapsules, which are distributed in a TIM gap filler, each have a shell that encapsulates a solvent. One or more organosilane-coated magnetic nanoparticles is/are covalently bound into the shell of each microcapsule. In one embodiment, (3-aminopropyl)trimethylsilane-coated magnetite nanoparticles are incorporated into the shell of a urea-formaldehyde (UF) microcapsule during in situ polymerization. To enable easy removal of one substrate affixed to another substrate by the enhanced TIM gap filler, the substrates are positioned within a magnetic field sufficient to rupture the microcapsule shells through magnetic stimulation of the organosilane-coated magnetic nanoparticles. The ruptured microcapsule shells release the solvent, which dissolves and/or swells the TIM gap filler, thereby reducing the bond strength between the substrates.
