Bee pollen moisture value is one of the quality parameters for this product some countries such as argentina, brazil, bulgaria, poland and switzerland have bee pollen regulations on quality parameters, but these are not clear regarding which method should be used for moisture determination the aim of this paper was to. The annals of the university dunarea de jos of galati fascicle vi – food technology, new series year iii (xxxiii) paper presented at the international symposium euro - aliment 2009, 9th – 10th of october 2009, galati – romania determination of the moisture content in infrared dried apples. Suitable for moisture determination in their procedure the acetone formed in the reaction is determined by infrared analysis during the course of this study a paper was presented by hager and baker (11) in which the use of dmp in a gas chromatographic method of moisture determination was suggested their paper was. The presence of moisture in the oil–paper insulation in a transformer drastically accelerates the aging process of the insulation and reduces the service life of the transformer to analyse the influence of moisture on the dielectric response of the oil–paper insulation and to precisely determine the moisture. Abstract: the variations in the low frequency dielectric spectra of mass impregnated insulation depending on its moisture content have been investigated for the calibration purposes a number of the impregnated paper samples was kept in the desiccators where different relative humidities were maintained thus obtained.
Moisture determination for food quality assessment conference paper january 2015 with 12 reads doi: 101051/metrology/20150015006 conference: conference: 17th international congress of metrology cite this publication francesca rolle at inrim istituto nazionale di ricerca metrologica. Using these wrappers between the steps of paper production helps the paper to remain tightly-knit and fresh while keeping out the excess, unwanted moisture away from the final product to determine which moisture meter best suits your moisture measuring needs with your paper products, feel free to. Understanding of wood moisture determination in fuel acquisition and testing this paper is designed to serve as a practical guide for anyone in the wisconsin industry in understanding the issues related to deter- mination of moisture content of woody biomass and reasonable methods that can be used to determine. Moisture determination balances provide a primary method for accurate moisture measurement by using the loss on drying (lod) method a liquid or solid sample is placed in the sample pan the integrated balance weighs the initial sample the balance's lid is closed, start button pressed, and the sample is dried.
From teabags, tissue paper, beyond photo-copying paper to heavy cardboards, there is a huge variety one thing in common is the need for a quick analysis technique in order to determine the physical parameters like thickness, grammage, wet extension and moisture content. Methods to determine moisture in waste paper 1 drying oven method - reference method determination of the percentage weight difference between raw waste and dried waste in the oven 2 core – boring – method with a drilling instrument a core is drilled out of the bale with a drilling instrument a core is drilled out of.
This paper describes a new method for the rapid determination of the moisture content in paper materials the method is based on multiple headspace extraction gas chromatography (mhe-gc) at a temperature above the boiling point of water, from which an integrated water loss from the tested sample. Abstract this paper gives the moisture content values obtained by five different oven-drying methods, in common use, for a number of non-oily cereal grains at different moisture levels it is shown that the values obtained for the moisture content of a grain sample given by various methods are different and that the amount of.
Review paper a review of moisture content determination in foods using microwave oven drying m bouraoui, p richard & j fichtali the university of british columbia, department of bio-resource engineering, 2357 main hall, vancouver this paper reviews the use of microwave drying for food moisture content de. Moisture content was measured by use of two different metso mr moisture analyzer machines in two different labs one at skogforsk in uppsala, sweden and one at port hawkesbury paper, point tupper, nova scotia, canada six different types of biomass materials were tested the method of determining. Preservatives in wood hygrometric methods measure the relative humidity of air that has come to equilibrium with the wood they are slower andless convenient than moisture meters, and are rarelyused in practice state forests of new soutii wales technical paper no 41 metilods of determining.
Hite paper 2 white paper mettler toledo 1 introduction in the field of moisture determination using loss on drying techniques, a common question is: can the drying oven method be replaced by fast halogen moisture analysis the simple answer is yes, as long as the results obtained by the two methods are. Defend the accuracy of moisture meter measurements or a customer simply does not believe moisture meter however, it is important to always rememberthat the oven-dry moisture content is what the meters are determine how moisture content changes or a piece of wood can be sliced to determine the moisture profile. Withdrawn rationale: this test method covers the determination of the moisture in all papers, paperboards, and paperboard and fiberboard containers, except those containing matter other than water that is volatile at 105°c formerly under the jurisdiction of committee d06 on paper and paper products, this test method.
