Objective:The effect of ultrasonic-assisted ionic crosslinking method on the peppermint capsule roundness was studied. Methods:The optimal treatment process was obtained through response surface optimization method, and the quality indicators of peppermint capsule was analyzed. Results: The results showed that, the optimum conditions of ionic crosslinking method were calcium ion mass fraction of 0.4%, soaking time of 20 min, solid/liquid ratio of 1.3∶1.0 (mL/g). Under the conditions, the strength of wet-capsule was 11.5 N, and the roundness of capsule was 0.033 mm. The optimum conditions of ultrasonic-assisted ionic crosslinking method were: ultrasonic time of10 min, ultrasonic power of 105 …
Effects Of The Inclusion Of Rice Hull Derived Bio-Oil On Wood Pellet Production, Tyler E. Lowe
Effects Of The Inclusion Of Rice Hull Derived Bio-Oil On Wood Pellet Production, Tyler E. Lowe
Theses and Dissertations
Wood pellet production has become an advancing industry for the sake of reducing greenhouse emissions into the atmosphere especially, in European Union countries. Researchers and industry executives seek new methods and materials to improve the pelletization process. Rice hulls or husks has the potential to aid in wood pelletization as they possess high calorific values. This study focuses on using rice hull derived bio-oil from pyrolysis, which will also decrease ash content, as an additive to aid in the wood pelletization process. Using two groups of rice hull derived bio-oil as an additive in wood pelletization: Group 1 uses heavy …

Neutral Sulfite Semi-Chemical Pulping Of Rapeseed Residues, Mohammad Ahmadi, Ahmad Jahan Latibari, Mehdi Faezipour, Sahab Hedjazi
Turkish Journal of Agriculture and Forestry
Neutral sulfite semi-chemical (NSSC) pulping of rapeseed residues from Karadj rapeseed growing fields was investigated. Rapeseed residue was collected from the research field at the Agriculture and Natural Resources Campus, University of Tehran located in Karadj. Cellulose, lignin, holocellulose, extractives soluble in alcohol acetone, 1% NaOH solubility, and ash were determined as 42 ± 2%, 17 ± 1%, 77.5 ± 2%, 2.2 ± 0.1%, 50.3 ± 1.6%, and 6%, respectively. Fiber length, width, and cell wall thickness were measured as 1.190 mm, 32 \mum, and 4 \mum. Three pulping durations of 20, 40, and 60 min and 5 chemical charges …
Withdrawal Strength Of Dowels In Plywood And Oriented Strand Board, Yusuf Zi̇ya Erdi̇l, Carl A. Eckelman
Withdrawal Strength Of Dowels In Plywood And Oriented Strand Board, Yusuf Zi̇ya Erdi̇l, Carl A. Eckelman
Turkish Journal of Agriculture and Forestry
Plywood and oriented strand board (OSB) are being used increasingly in the construction of upholstered furniture frames. Yet there is little information available concerning the holding strength of various fasteners, and, in particular, dowels in these materials. A study was conducted accordingly, to obtain basic information about the holding strength of dowels in both plywood and oriented strand board. Results of the tests were incorporated into predictive expressions that allow designers to estimate withdrawal strength as a function of the diameter of the dowels, their depth of embedment and the density of the composite material. Given the variability of the …
