densification of biomass material that usually has a low density is proper way to increasing density,reduce transportation cost and simplify storage and distribution of these materials. pellet productionusing extrusion process is a common method for densification. the goal of this research isoptimization of specific energy consumption for extrusion process considering its effect on pelletdensit...

The aim of this work was to evaluate two operating parameters of seed drying (temperature and initial moisture content) on the tocopherol content of canola oil. The raw material was characterized by moisture, oil, protein, crude fiber and ash content. Seeds at 13.6% and 22.7% moisture content (dry basis, db) were dried at temperatures in the range of 35-100 °C to a safe storage moisture of 7% d...

In the pharmaceutical industry, it is always important to have reproducible processes and raw materials of high quality to ensure good quality products. AstraZeneca, that is a leading manufacturer of different pharmaceuticals, works according to GMP to make sure that their processes deliver products of the same quality every time. A problem that has occurred at AstraZeneca is when a raw materia...

BACKGROUND The value of water activity in extruded products constitutes a significant indicator of their quality and stability. The state, in which water is found in extruded products, is an indicator of the conducted extrusion process and the used raw material. MATERIAL AND METHODS The aim of the study was to assess water activity in extruded products made from a mixture of com grits with 12...

– Local content policy in Nigeria promotes the development of innovative indigenous technology aimed at contributing to national science and technological development. Consequently, bioremediation agent (Ecorem) was formulated from Nigeria local raw materials as a contribution to enhanced environmental performance in the petroleum sector. As part of evaluating kinetic mechanism of this product,...

Issue: The moisture content of a fill material will affect its compaction characteristics and needs to be evaluated during quality control of the fill operation. When the fill is drier than its optimum moisture content, any moisture in the fill serves as a lubricant and helps the relative movement of the particles when densifying under vibratory compaction. When the fill is wetter than its opti...

the presented study shows a simple way for optimization of extrusion process, which was used for deterioration of cyanogenic glycosides – antinutritive components of linseed, with minimum damage of essential alpha-linolenic acid (ala) at the same time. extrusion of the material was done on a laboratory single screw extruder. content of hydrogen cyanide (hcn) as a measurement of cyanogenic glyco...

This thesis focuses on two main areas: methods for assessing regional supply potentials of reed canary grass (Phalaris arundinacea L.) (RCG); and process technology for the production of high-quality RCG pellets. Partial equilibrium modelling, incorporating a break-even price approach, was used to examine supply potentials for RCG in Västerbotten County, northern Sweden. A remote sensing method...

Nacrtak Wood fuel quality attributes have to be considered by logistics planners if fuel procurement from forests and energy production at the plant are considered simultaneously. The single most important quality attribute is the moisture content (MC) of chips or raw material delivered to energy plants. It affects heating value, storage properties, chipping and transport costs of the fuel. To ...
