“…However, the variation among the feeds were modest, ranging between 33.2 N to 52.3 N. Besides, the hardness values of the feeds used in the present experiment were high compared to other experiments (Aas et al, 2011b, Morken et al, 2011, Morken et al, 2012. Hardness of pellets is positively associated with pellet diameter (Abdollahi et al, 2012, Kaliyan & Vance Morey, 2009). The higher hardness of pellets used in the present experiment may thus be explained with the larger diameter of the pellets compared to other experiments (Aas et al, 2011b, Morken et al, 2011, Morken et al, 2012.…”

Feed pellets in modern aquaculture must be of high physical quality to withstand mechanical impacts. However, physical quality of feed has been shown to affect nutritional responses. In the present study, different moisture contents were used to modify physical feed qualities.Effects of dietary moisture content on physical feed quality, feed intake, nutrient digestibility and growth performance in Atlantic salmon were investigated. Different drying times of four commercial-like extruded diets resulted in in dry matter contents of 95.9%, 94.1%, 92.3%, 90.8%. A fifth diet containing 70% dry matter was made

“…is optimal for manufacturing of biomass briquette free of cracks. The right amount of moisture in the biomass acts as a facilitator of natural binding agents and as a lubricant [3,6]. Many studies have indicated that feedstock moisture content below 8 % (w.b.)…”

“…The briquette moisture content after the durability test was determined based on ASABE Standard S358.2 [21]. Durability rating (DR) represents the measure of shear and impact forces that briquettes could withstand in the course of handling, storage, and transportation processes [6,12,23]. The briquette DR was tested based on ASABE Standard S269.4 [22] by tumbling ten briquettes (representing the ten replicates of each combination) in a tumbling durability tester for 3 min at 40 rpm.…”

“…A number of researchers have discussed in detail how process variables (i.e., die temperature, compression pressure, die geometry, and retention time), feedstock variables (i.e., moisture content and particle size and shape), and biomass composition (i.e., protein, fat, cellulose, hemicelluloses lignin, etc.) play a major role in densified biomass quality [3][4][5][6][7][8][9][10][11][12][13]. Pelleting at high die temperatures can result in plasticization of components like protein and starch, and softening of lignin [14].…”

“…In general, briquetting or cubing may require coarse grinding or one-stage particle size reduction, whereas pelletizing requires two or more stage particle size reduction, making for a lower energy requirement of the process. Kaliyan and Morey [6,7] and Adapa et al [10] investigated the effects of particle size on the densification characteristics of corn stover, switchgrass, and alfalfa and concluded that decreasing the geometric mean particle size helps to increase the density of densified biomass.…”

Impact of process conditions on the density and durability of wheat, oat, canola, and barley straw briquettes

et al. 2014

The present study is to understand the impact of process conditions on the quality attributes of wheat oat, barley, and canola straw briquettes. Analysis of variance indicated that briquette moisture content and initial density immediately after compaction and final density after 2 weeks of storage are strong functions of feedstock moisture content and compression pressure, whereas durability rating is influenced by die temperature and feedstock moisture content. Briquettes produced at a low feedstock moisture content of 9 % (w.b.) yielded maximum densities >700 kg/m 3 for wheat, oat, canola, and barley straws. Lower feedstock moisture content of <10 % (w.b.) and higher die temperatures >110°C and compression pressure >10 MPa minimized the briquette moisture content and maximized densities and durability rating based on surface plots observations. Optimal process conditions indicated that a low feedstock moisture content of about 9 % (w.b.), high die temperature of 120-130°C, medium-to-large hammer mill screen sizes of about 24 to 31.75 mm, and low to high compression pressures of 7.5 to 12.5 MPa minimized briquette moisture content to <8 % (w.b.) and maximized density to >700 kg/m 3 . Durability rating >90 % is achievable at higher die temperatures of >123°C, lower to medium feedstock moisture contents of 9 to 12 % (w.b.), low to high compression pressures of 7.5 to 12.5 MPa, and large hammer mill screen size of 31.75 mm, except for canola where a lower compression pressure of 7.5 to 8.5 MPa and a smaller hammer mill screen size of 19 mm for oat maximized the durability rating values.
