Modeling, simulation, and analysis of a soybean meal desolventizing equipment

  • First Published: 19 February 2019

This study presents a mathematical modeling for the simulation of the desolventizing process occurring in a Desolventizier-Toaster (DT) equipment. The development model can be used to optimize the desolventization process, with respect to the recovery of Hexane and the use of energy. The comparision of the results obtained from the simulation of the proposed model and the data of a real DT does not reach 8%.

Optimization of ultrasonic-assisted enzymatic extraction of β-carotene from orange processing waste

  • First Published: 18 March 2019

  • This study evaluates ultrasound-assisted enzymatic extraction of β-carotene.
  • Optimum treatment was 0.40% pectinase, 115.55 min ultrasonic time, and 5.11 pH.
  • Optimum treatment led to maximum β-carotene of extract from orange waste powder.
  • Scanning electronic images showed more β-carotene obtained from more porous structure.
  • FTIR showed ultrasound and pectinase did not destroy functional groups of extracts.

Performance comparison of mixed mode and indirect mode parallel flow forced convection solar driers for drying Curcuma zedoaria

  • Performances of MFSCD and IFSCD with OSD are compared for drying of white turmeric.
  • Final moisture content was achieved in 24, 31, and 59 hr in MFSCD, IFSCD, and OSD.
  • MFSCD saves about 60% of time compare to OSD for drying of white turmeric
  • Specific energy consumptions of MFSCD and IFSCD are 2.84 kWh /kg and 3.15 kWh /kg.
  • Presented antioxidants and TFC values of fresh, solar, and open sun samples.

Grading bunch tightness for grape by multiperspective imaging approach coupled with multivariate classification methods

A multiperspective imaging structure was developed to capture the whole surface. Descriptors about the tightness of bunch were digitalized by image process, instead of the manual measurements. Multivariate modeling methods were employed to grade the tightness of grape bunch.

Development of a novel 2D single coffee bean model and comparison with a 3D model under varying heating profiles

A 2-D single coffee bean model was developed to predict the bean temperature during roasting. The model has proven to be 30 times faster than 3-D model and could be used for an accurate profile roasting (varying heating conditions) with minimum absolute errors.

Evaluation of extraction technologies and optimization of microwave and ultrasonic assisted consecutive extraction of phenolic antioxidants from winery byproducts

Evaluation of extraction technologies and optimization of microwave and ultrasonic assisted consecutive extraction of phenolic antioxidants from winery byproducts

Acid, enzyme, ultrasonic, and microwave were used to assist extraction of polyphenols in grape pomace, skins, and seeds. The relationship among extraction technologies, polyphenolic content and antioxidant capacities was analyzed by principal component analysis (PCA). The effective extraction condition for specific target was optimized by response surface methodology.

Evaluation of the efficacy of subcritical water to enhance the lipid fraction from activated sludge for biodiesel and oleochemicals production
RESEARCH HIGHLIGHTS

  • Greater amount of activated sludge biomass and lipids were recovered from the total suspended solid than total dissolved solid
  • Subcritical water technology can be used to increase lipid yield from activated sludge
  • An increase in lipid yield of 145% at the optimum conditions of 280°C, 40 min, 15 mL of water and biomass loading of 5% was obtained.
  • Higher proportion of unsaturated fatty acid suggests that the biodiesel from the activated sludge would have a high quality.

Changes in texture and molecular forces of heated-induced egg white gel with adding xanthan gum

  • Xanthan gum and egg white gel had two aggregation phenomena.
  • Electrostatic interactions were explored using infrared and Zeta-potentials.
  • Disulfide bonds played an important role in hybrid gels.
  • The sheet-like gel structure was observed at high concentrations of xanthan gum.
