Coating process of corn grains using treatment machine with brush screw conveyor

Abstract

After the harvesting process, agricultural products (grains, fruits, vegetables, etc.) cannot be used directly for different purposes such as : preservation, consumption, industrialization, marketing, sowing, etc.) Prior to receiving a particular destination, it is necessary and obligatory for the harvested products to undergo preparatory operations on conditioning and quality control in order to meet different uses. In order to improve grain health and to avoid production decline and quality worsening due to the attack of diseases and pests transmitted through grains, treatment has long been used for some species and generalizes rapidly with better results of seed treatment by various means -physical, chemical or biological. Success in grain crops begins with efficient seed treatment, so one of the criteria for assessing the seed quality is its chemical treatment with major implications for the development of future crops. The development of an appropriate technology for the treatment of cereal seeds and technical plants requires a thorough analysis of all the factors involved in the chemical treatment of the seeds (seed quality, their destination, particularities of seed conditioning according to the variety, particularities of the equipment used). The paper presents experimental research results conducted on a machine with brush screw conveyor, which allowed the variation of operating parameters that are graphically represented. The testing methodology for treatment equipment has been developed according to the construction features and functional parameters. Therefore, we determine the interdependence between the coverage degree and the functional parameters that were tested and we formulate recommendations for the use of these types of machines.

Factors that influence coverage degree in seed treatment equipment having brush screw conveyor

“…The research and the experimental activities were performed using a machine that was designed and produced at INMA Bucharest using the same methodology and the same raw material [10] Fig. 2.…”

Enhancement of Agricultural Materials Separation Efficiency Using a Multi-Purpose Screw Conveyor-Separator

“…The scientific principles of telescopic screw conveyor design have been developed in [15,16]. Some theoretical substantiation of the design, kinematic, and dynamic parameters of the proposed operating parts of flexible screw conveyors and automated taking of bulk material has been presented in studies [17][18][19]. The theoretical substantiation of pneumatic transporters for bulk material transportation on curvilinear routes by means of periodic dosed supply of air streams along the transport hose periphery has been made, and a model of bulk material interaction in the transport flow including the determination of the most efficient design, kinematic, and dynamic parameters of a pneumatic-mechanical transporter has been developed [16,18], as well as the technological support of transport-technological machines operation and parts production have been developed in study [20].…”

Fault Detection and Prediction for a Wood Chip Screw Conveyor

“…Screw conveyors are made of a wide range of different types of materials that can be steel, stainless steel variants, plastic or other materials.Screw Conveyors have as main objective to supply silos, carry out loading and unloading of materials or even supply other types of industrial machines. As a rule, they are widely used in the food, chemical and pharmaceutical industries[30,12], among others.…”
