Modelling Rupture Force based on Physical Properties – a Case Study for Roma Tomato (Solanum lycopersicum) Fruits CIGR Journal
Lak, Mohammadbagher; Minaei, Saeid; Soufizadeh, Saeid; Banakar, Ahmad.
Biophysical properties of agricultural materials are important in designing of processing machines. In this study, some physical properties of tomato (Solanum lycopersicum) fruits were determined and their mutual relationships were studied. Dimensions (major diameter, minor diameter, and length), mass, volume, fresh and dry matter weight, as well as rupture point under uniaxial loading were measured. Other properties; including Poisson's ratio, modulus of elasticity, energy for rupture, density, arithmetic mean diameter, geometric mean diameter, diameter of equivalent volume sphere, and sphericity were calculated accordingly. Statistical analysis of the data indicated significant correlations between the rupture force and fresh weight, volume, dry weight,...

Estimation of head rice yield by measuring the bending strength of kernels after drying by different drying methods CIGR Journal
Nassiri, Seyed Mehdi; Etesami, Seyed Mohammad.
In this study, two local rough rice cultivars (long and medium grain) were dried by three different drying methods including indirect and mixed-mode active solar dryers, and continuous dryer at three temperature levels of 35°C, 45°C and 55°C.  Bending strength of brown rice kernels, percentage of fissured kernels and head rice yield were measured and evaluated.  No significant difference between bending strength of dried rough rice kernels by indirect and mixed-mode active solar drying methods was observed.  Drying by continuous dryer improved the mechanical strength of kernels by providing tempering periods.  Medium size kernels depicted more strength than longer ones.  Strong relationships were established between the bending strength of the brown rice...

Bioplastics production from agricultural crop residues CIGR Journal
Samer, Mohamed.
Bio-based plastics have a huge market and a wide range of applications and then have become increased in economy and research. Due to the environmental hazard on all organisms and the pollution that happens in all natural resources such as air, water, plants and soil pollution and the limitation of quantity of fossil resources on our planet, the future cannot depend on petro-plastics. All fossil products should be replaced by bio-based products. The petro-plastics are one of the fossil products which should be replaced by bio-based plastics. In this study, potato peels were used to produce bioplastics by the extraction of the starch from the peels and adding some ingredients such as water, glycerin, vinegar and industrial colors with different ratios and...

Evaluation of Kansei Engineering-based Sensor for Agro-industry (KESAN) CIGR Journal
Ushada, Mirwan; Khuriyati, Nafis; Agustriana, Silvia; Okayama, Tsuyoshi.
This paper highlighted evaluation of a device for workload monitoring named as Kansei Engineering-based Sensor for Agro-industry (KESAN). As a newly developed device, usability and performance factors have not been evaluated on KESAN. The research objectives were: 1) To evaluate the usability of KESAN as an appropriate technology; 2) To evaluate the performance of KESAN for the workload monitoring device. Usability was evaluated by 30 selected manager of small medium-sized agro-industries in Yogyakarta Special Region. Usability evaluation indicated most attributes were accepted by the manager. Device performance was evaluated on 9 (Nine) selected workers from fish processing, crackers, and bakery industry. 7 (Seven) workers were evaluated on consecutive...
