| Sweet orange is a important citrus fruit grown throughout the world as it rich in phytonutrients properties and excellent source of vitamin C. The conventional clarification process involves more costs with personnel, equipment, and physical space. As an alternative, microfiltration (MF) has been applied in fruit juices for clarification. Clarification of sweet orange juice was carried out by microfiltration process using 0.2 µm size cellulose acetate MF membrane in a stirred cell. Flux decline was majorly due to deposits formed with soluble and suspended fraction of pectin, proteins and fibers, forming a low methoxy gel layer on membrane surface causing fouling during clarification. Long term flux decline was dictated by intermediate pore... |

| Dynamic behavior of agricultural implements has always been a challenging topic for researchers. In precision farming, precise control of the agricultural implements is a very important task. To study the dynamics of agricultural implements, Researchers conduct field experiments as well as laboratory tests. These methods are very costly and the measurements are usually associated with some errors. Providing well-controlled experimental conditions in practice is very difficult, if not impossible. In this article, the capability of the SolidWorks in simulation and predicting the dynamic behavior of a conventional sprayer boom is discussed. To validate the results, field tests were conducted using a conventional sprayer boom. The results showed that there was... |

| Water is basic source of the farming with limited storage. Out of available land 64% is engaged by the farming and needs nearly 85 % of clean water of total water storage. Proper irrigation helps to improve quality of soil and the growth of crops. The farmer depending upon condition of soil and available water resource has to apply intelligence to get realistic decisions to reduce the wastage of water and ensure full utilization of the water. This gives challenging opportunity to pertain theory and idea of Artificial Intelligence (AI) in the process of water irrigation. In this paper, an intelligent approach for the water irrigation of crop is proposed. Smart Fuzzy Water Irrigation System (FWIS) using Internet of Things (IoT) includes two types of nodes... |

| Fruit sorting determines market value. Farmers and traders commonly use physical-eye inspection and handpicking for sorting, but this is labour-intensive and ineffective. This research work aims to develop a sensor-based automated system for sorting freshly harvested tomato fruits. The automated system sorts tomato fruits into small, medium, and big sizes for market value. To evaluate the system performance, 115 fruits were machine-sorted and compared to eye-inspection and physical measurement. Physical measurement was done by measuring the minor, intermediate, and major diameters of each fruit with a Vernier calliper. While the eye-inspection was carried out by manual human examination with the eye. Results show average percentage error between physical... |

| This research aimed to manufacture a simple fiber extraction machine. The machine prototype consisted of available raw materials. The beater cylinder is the most significant component in this machine. The electric motor of 0.75 kW was used to rotate the beater cylinder. The machine theory is based on the repeated rapid beating of the beaters on a slice-stem of banana. This beating simulated what labor does by using hand hammers to eliminate the juice and extract the fibers. The machine was tested under three rotational speeds of the beater cylinder 650, 750, and 850 rpm and using three beater cylinders with a different number of beaters 8, 10, and 12. The fibers produced by the machine were straight, of good quality, and not shredded, this was achieved in... |

| Teff (Eragrostistef (Zucc.)Trotter) is a typical crop growing in most areas of Ethiopia, with the first area coverage. Threshing of teff can be performed indifferent ways; by hand beating, animal trampling and use of stationary threshers. In all cases of teff threshing, separation and cleaning are the most tedious and time consuming activities. In this research, the design effect of a newly developed type threshing unit was compared against SG-2000 stationary thresher. The comparison was focused on two independent variables: feed rate and drum speed, with three levels 275, 325 and 400kg.hr-1; and 900, 1000 and 1200 rpm respectively. The result revealed mean values of the threshing capacity, cleaning efficiency and separation efficiency are 42.30 and 45.81... |

| This paper aimed at modeling the effect of dryer configurations on the thin-layer solar drying kinetics of ogbono seeds. Ogbono seeds were dried using a solar drying system, which was a forced convection distributed type solar collector, equipped with a sun-tracking mechanism. The seeds were dried at four different tilt angles of 0, 5, 10, and 15°; two absorber plate thicknesses of 1.5 mm and 2.7mm; and a constant air velocity of 2 ms-1. The drying data obtained from the experiment was fitted to six thin-layer drying predictive models. The effective moisture diffusivities at varying treatments as well as the activation energy of the ogbono seeds were determined. Results from the experiment revealed that the drying kinetics of the seeds varied with the... |

| Optical seed mass flow sensors are widely used on seed drills and planters. An important challenge in these sensors is their malfunction in a dusty condition. Dust caused by soil and seeds may sit on the light elements and disrupt its function. In this study, an approach was developed to compensate this effect. A non-contact intelligent system with infrared diodes and a microcontroller with ARM architecture was built up to monitor the seed flow in the delivery tube of seed drills. At the hardware phase, a glass with a different radius of curvature was installed in front of the elements. The semi-cylindrical glass placement in front of the optical elements meant that the arrangement was sealed against dust. Besides, the fall of the seeds tangential to the... |
