Journal PapersJournal of Agricultural Machinery , Volume 11 , Issue 2, 2021 September 23, {Pages 331-342 }

Abstract

Introduction One of the most important and sensitive steps after walnut harvesting is the separation of the kernel from its shell. Walnut rupture force is an appropriate criterion for design with high performance and better quality, which can be used as the basis for designing and adjusting the various parts of machines that are in contact with walnut. The lower rupture force caused the less energy requirement to separate the walnut kernel from the shell. The use of ultrasound in ambient fluids is well known to cause turbulence and biological cell rupture. These effects arise principally from the phenomenon known as cavitation which can scour surfaces and damage cellular material. Therefore the object of this study is to find the effect of

Journal PapersIranian Journal of Biosystems Engineering , 2020 August 22, {Pages }

Abstract

Herb stems and leaves must be sheared and separated before any processing and post harvest operations. This is non-mechanized since parts of the stem having fewer leaves are cut manually. This research is focused on the design and development of an automated machine for precise cutting of harvested herb stems. The system detects plant's leafy area from the leafless stem section by using machine vision. For this purpose, herb stems are placed in clamps fixed on a conveyor belt. A digital camera takes images of the passing samples. Image processing is performed to determine the proper cutting position on the stem. The shearing system is then vertically moved to the determined cutting position to make a precision cut. The designed system cuts

Abstract

So far, many studies have been conducted on heat transfer nanofluids and various nanofluids have been synthesized and evaluated by different nanoparticles. In the present research, the use of biodegradable carbon quantum dots (CQDs) to synthesize heat transfer nanofluids was investigated for the first time. In fact, CQDs are a new generation of carbon nanoparticles and one of the advantages of which is their very small size that facilitates the prepared of nanofluids at very low concentrations with high stability. In the present research, CQDs were synthesized based on microwave method using commercial ammonium hydrogen-citrate as precursor. The nanofluid samples were synthesized based on car radiator coolant and CQDs at the concentrations

Abstract

Nowadays, energy is the most challenging issue in the world. Although nanotechnology has been promising in offering huge developments in various fields, there are still concerns about the potential threats of nanotechnology products and applications. The concerns are mostly about the possible entrance of nanoparticles into body and their toxicity. As metallic and metal oxide nanoparticles might have toxic effects on living organisms, the use of biocompatible nanoparticles can considerably reduce these concerns. In this research, a combination of diesel-biodiesel-water-biodegradable nanoparticles was used to optimize fuel consumption, reduce pollutants, and enhance diesel engine performance for first time.

Fluidized Bed Drying Characteristics of Soybeans

S Minaei, H Darvishi, MH Khoshtaghaza
Journal Papers , 2018 February 21, {Pages }

Abstract

The present study investigated the influence of air temperature and velocity on the drying kinetics and specific energy consumption during fluidized bed drying of soybean at 80, 100, 120 and 140?C and airflow rates of 1.8, 3.1 and 4.5 m s-1. Six mathematical models for describing the fluidized bed drying behavior were investigated. The value of the drying rate coefficient (k) increased with increasing air temperature and velocity and thus reduced the drying time. Although the Midilli model showed the best fit, the Page's model was selected, since it had almost a similar performance but the model is simpler with two parameters instead of four. The drying of soybean seeds took place in the falling rate period and was controlled by moisture di

Abstract

This study aimed to examine the effectiveness of co mbined microwave-ultrasonic pasteurization system on Escherichia coli and vitamin C content in sour cherry juice (SCJ). Based on the findings, microwave output powe r, ultrasound power, and ultrasonic exposure time as well as the microwave-induced temp erature were the most effective factors in reducing E. coli and vitamin C content. In addition, the microwave-i nduced temperature and ultrasonic exposure time, as indepe ndent variables, were both effective on E. coli removal. At higher temperatures, the effectiveness of ultrasonic waves as well as cavitation intensity declined. However, their combi ned effect

Abstract

Initial low cost of pesticides and lack of knowledge on the part of agricultural producers has led to an overuse of pesticides, with dangerous consequences. On the other hand, today pesticides have an important role in the increment of agriculture products. Therefore, in recent years, the major aims of agricultural, environmental and even the food industry researchers have been to reduce the usage of chemical materials in agricultural applications. To achieve this, variable rate application in sprayers using different technologies such as machine vision, ultrasonic sensors, spectrometry, laser scanning, as well as pest identification and classification, have been applied in recent studies. This paper reviews these works reported in the 21 c
