Abstract:
This invention relates to a system for and method of blanching, steaming, and/or boiling a food product (101), the method comprising applying steam of a gas (103) to at least a part of a surface area (101') of a food product (101) for a predetermined period of time thereby blanching, steaming, and/or boiling at least a part of said food product (101), wherein the method further comprises applying airborne high intensity and high power acoustic waves (104) to at least a part of said steam of gas (103) causing the part of said steam of gas (103) to oscillate substantially at the frequency and substantially with the intensity and power of the acoustic waves (104). In this way, a blanching, a steaming and/or a boiling effect can be improved by application of a combination of steam of a gas and airborne high intensity and high power acoustic waves where the sonic impact of the acoustic waves increases and enhances the blanching, steaming, and/or boiling effect of the steam. This entails that the food product (of plant or animal origin) to a larger extent will obtain the desired properties (absence of inherent enzymatic activity, preservation of colour, unchanged/only slightly changed texture and water binding capabilities).
Abstract:
The invention relates to a method for providing a density profile of a plate-shaped body by means of an X-ray radiation source (1), the radiation of which is directed towards the plate-shaped body (5) and scattered therefrom, the radiation scattered by the plate material from a specific depth of the plate-shaped body being taken as a measurement of the density at the respective depth. The method is characterised in that the radiation scattered by the plate material at different depths is observed through a narrow slot (6), which is placed substantially perpendicular to the radiation direction, utilizing that there is an unambiguous relation between the scattering angle and depth, said scattered radiation being registered by means of an array of closely abutting detector elements for determining the density profile. An advantage of this method is that it is fast and does not require movable parts. Another advantage is that the complete depth profile is measured at the same time, particularly that the top side and the bottom side of the plate-shaped material are identified at the same time, whereby measuring series may be corrected correctly irrespective of the movements of the plate between sub measurements.
Abstract:
A method and a device to be used in the process of manufacturing plates, such as fibreboards or the like boards, where the raw material in form of biomass particles, such as wood fibres or the like, applied with a thermosetting binder is spread onto a forming belt to form a mat, and where said mat by means of a hot press is compressed into the desired thickness of the finished plate and the thermosetting binder is hardened. According to the invention the thermosetting binder is applied to the dried biomass particles in an airborne process, where the intense and homogeneous contact of the biomass particles and the droplets of fluent binder are facilitated by the use of ultrasound generated by the use of compressed air, water steam or another gas. Further measures to intensify the contact between the biomass particles and the binder droplets utilizing the dipole moment of the biomass particles, at the same time preventing the binder to stick to the walls of the device, as well as measures and to control moisture content and temperature of the binder-loaded particles are disclosed.

Abstract:
The present invention relates to a method of joining a metal part 1 and a non-liquid polymer part 2. The first step of the method is to attach a primer 4 to a metal surface 3 of the metal part 1. The primer 4 is then polymerized so that the metal surface 3 is at least partly covered with surface immobilized polymer brushes 5. Then the metal surface 3 with the polymer brushes 5 is brought into contact with a polymer surface of the polymer part 2, so that an interface is obtained comprising the metal surface 3, the primer 4, the polymer brushes 5 and the polymer surface. Finally, the interface is heated by use of laser welding until the polymer brushes 5 and a part of the polymer part 2 melt or soften and mix to such an extent that the metal part 1 and the polymer part 2 remain joined after cooling. The welding may e.g. be performed so that so that welding seams are obtained along equidistant lines across the surface.
