Experimental and Theoretical Fuel Property Comparison of Four Different Waste Biomass with A Commercial Counterpart

This study focuses on determining the fuel properties of apple pulp, pomegranate seeds, pomegranate peel and orange peel wastes and converting them into pellet fuel. Within the scope of the study, the organic wastes were dried, ruined into small pieces and then pressed to take the pellet form. Moisture content, ash content, volatile matter determination, fixed carbon content, total sulfur content, hydrogen content, lower heating value and higher heating value were analyzed as solid fuel characterization process. Experiments were carried out in an internationally accredited laboratory in accordance with ASTM and TS EN ISO/IEC 17025 Standards. Considering the results, it was determined that the pellet obtained from fully dry state pomegranate seed had a calorific value of 4244 kcal/kg, whereas the commercial pellet was 4759 kcal/kg under the same conditions. On the other hand, the moisture contents of the commercial pellet and pomegranate seed sample were 5.42% and 1.83%, respectively. The drying process was one of the costliest stages of pellet production. The low moisture contents can reduce the production cost and shorten the time.

USED OF WOOD PELLET FOR FUEL PRODUCTION TOFU IN UKM KAB. KEDIRI

Wood pellet is an alternative fuel made from wood waste, is one of the renewable fuels that is environmentally friendly, has a cylindrical shape and is hard, this is one of the energy conversions where the process of changing the energy form of wood waste which is randomly sized is converted into a cylindrical pellet form. This service is carried out to determine the impact of rising fuel prices on the pattern of fuel use in the tofu production process in Kab. Therefore, it is necessary to analyze the efficiency of the system analyzed, namely the efficiency of the combustion system in the production of tofu.

From the analysis that has been done to get wood pellet fuel to get maximum results for soybean cooking in a burning time for 1 hour it takes 1/2 kg of wood pellets, if done one day by burning for 8 hours in the soybean porridge cooking process it takes 4 wood pellets kg.

Experimental Determination of Coefficients for the Renner Model of the Thermodynamic Equation of State of the Poly(butylene succinate) and Wheat Bran Biocomposites

This paper presents the assumptions of a thermodynamic equation of state for polymers according to the Renner model. The experiments involved extruding a biocomposite based on poly(butylene succinate) that was filled with ground wheat bran with its size not exceeding 200 μm. The biocomposite was produced in pellet form with three different contents by weight of wheat bran, i.e., 10%, 30% and 50%. All specimens were examined for their thermodynamic p-v-T characteristics. Taking advantage of the SimFit module of Cadmould 3D-F, experimental results were used to determine the coefficients of thermodynamic equation of state for the tested biocomposite according to the Renner model. The coefficients were then used to calculate transition temperature and to create diagrams illustrating the relationship between pressure, temperature and specific volume for the tested biocomposite. The obtained results can serve as a basis for assessing the suitability of the biocomposite for injection molding, selecting technological parameters of this process, as well as for analyzing shrinkage and defects of injection-molded parts.

Fluorimetric Analysis of Five Amino Acids in Chocolate: Development and Validation

Amino acids present ergogenic action, helping to increase, protect, and restore the muscular system of young athletes. Moreover, the encapsulation of five relevant amino acids in chocolate pellet form will appeal to them, facilitating their daily consumption. A reliable HPLC fluorimetric method was developed to detect and quantitatively determine L-Leucine, L-Isoleucine, L-Histidine, L-Valine, and β-Alanine in chocolate using aniline as an internal standard. Experimental design methodology was used to investigate and optimize the clean-up procedure of the samples. Therefore, three extraction techniques (solid-phase extraction (by two different SPE cartridges) and liquid–solid extraction (LSE)) were compared and evaluated. The LOQ values in chocolate varied from 24 to 118 ng/g (recovery 89.7–95.6%, %RSD < 2.5). Amino acids were pre-column derivatized with o-phthalaldehyde (OPA), while derivatization parameters were thoroughly investigated by experimental design methodology. The analysis was performed by HPLC-fluorescence (emission: λ = 455 nm, excitation: λ = 340 nm) method using a C18 column and a mixture of phosphate buffer (pH = 2.8; 20 mM)-methanol as a mobile phase in gradient elution. The method was validated (r2 > 0.999, %RSD < 2, LOD: 10 ng mL−1 for histidine and leucine, 2 ng mL−1 for alanine and valine, and 4 ng mL−1 for Isoleucine) according to the International Conference on Harmonization guidelines.

Effects of Flavonoids Extracted from Citrus aurantium on Performance, Behavior, and Rumen Gene Expression in Holstein Bulls Fed with High-Concentrate Diets in Pellet Form

Flavonoid supplementation may modify the behavior and rumen inflammatory response of fattening bulls, and this could be related to the concentrate presentation (mash or pellet) form. In the present study, 150 Holstein bulls (183.0 ± 7.53 kg BW and 137 ± 1.8 d of age) were randomly allocated to one of eight pens and assigned to control (C) or (BF) (Citrus aurantium, Bioflavex CA, HealthTech Bio Actives, Spain, 0.4 kg per ton of concentrate of Bioflavex CA, 20% naringin). Concentrate (pellet) intake was recorded daily, and BW and animal behavior fortnightly. Animals were slaughtered after 168 d of study, and ruminal epithelium samples were collected for gene expression analyses. Treatment did not affect animal performance; however, BF supplementation reduced agonistic interactions and oral non-nutritive behaviors and increased the time devoted to eating concentrate and ruminating activity (p < 0.05). The gene expression of some genes in the rumen epithelium was greater or tended to be greater in BF than C bulls (bitter taste receptor 16, cytokine IL-25, β-defensin; p < 0.10; pancreatic polypeptide receptor 1 and tumor necrosis factor alpha; p < 0.05). In conclusion, flavonoid supplementation modifies the expression of genes in the rumen epithelium that could be related to inflammation and animal behavior modulation.

140 Influence of Enogen Feed Corn and Conventional Yellow Dent Corn in Pelleted or Meal-based Diets on Finishing Pig Performance and Carcass Characteristics

Previous research has indicated that starch gelatinization during the pelleting process is greater for Enogen® Feed corn compared to conventional yellow dent corn. Increasing starch gelatinization in the pellet increases the starch digestibility in the pig, which potentially leads to increased growth rate. Therefore, the objective of this study was to determine the effects of feeding Enogen Feed corn in meal or pellet form on finishing pig growth performance and carcass characteristics. A total of 288 pigs (53.0 ± 0.5 kg) were used with 8 pigs/pen and 9 pens/treatment in a 72-d study. Treatments were arranged in a 2×2 factorial with main effects of corn source (Enogen Feed corn or conventional yellow dent corn) and diet form (meal or pellet). Main effects of corn source and diet form as well as their interactions were tested. Pelleting parameters were established with a target conditioner temperature of 82.2°C and corn moisture of 13 to 14%. When pelleting the diets, the conditioning temperature for conventional yellow dent corn averaged 68.4°C and Enogen Feed corn averaged 67.7°C. The hot pellet temperature for conventional yellow dent corn averaged 75.1°C and 75.8°C for Enogen feed corn. For overall performance (d 0 to 72), no interactions between corn source and diet form were observed (P &gt; 0.05). There was a tendency (P &lt; 0.10) for slightly improved average daily gain (ADG) and gain:feed ratio (G:F) for pigs fed conventional yellow dent corn compared to those fed Enogen Feed corn. Pigs fed pelleted diets had increased (P &lt; 0.001) ADG, G:F, and hot carcass weight compared to pigs fed meal diets. In summary, feeding pelleted diets to finishing pigs increased ADG and G:F compared to those fed meal-based diets. There were no major differences observed between corn sources or interactions between corn source and diet form on growth performance.

Effect of processing methods on the utilization of shrimp waste by broiler chickens

Two hundred and forty unsexedd broiler birds of Anak breeds af one week of age were used to study the utilization of potash treated shrimp waste meal (SWM) in broiler diets fed as mash or pellet form in a 2x2x2 factorial experiment. The birds used were randomly allotted to eight treatment groups with three replications. SWM used was either polash treated or untreated, plate willed or hammer milled. Growth performance, muirient utilization, and carcass characteristics were measured. Potash treatment of SWM led to a significant increase (P<0.05) in final live weight of the birds at starter phase, but such effear was not noticed at finisher phase. Starter broilers fed mash diets had a significantly (P<0.05) higher mean final live weight (579.08), than those seed pellet diet (493.12). but the difference at fisher phase was not significant. The processing methods did nor significantly (P>0.05) improve the performance of the birds or finisher phase, though slight improvement was noticed in bird's fed pelleted diets. The processing methods did not significantly (P>0.05) influence the protein retention, ash and ether extract digestibility at starter phase. Crude fibre digestibility was significantly (P<0.05) improved by plate milling and pelleting of the diets, and the interactions of the processing methods. Dry marier digestibility and crude protein retention of finisher broilers were significantly (P<0.05) improved by the dietary treatments. It was concluded that the treatments employed yielded no commendable performance in broilers. Pelleting of SWM based diets slightly improved iis utilization by finishing broiler chickens.
