Improvement and Optimisation of vibrating tables used in agri-foodstuffs sector


A research team of the Public University of Navarre (Basque Country), under the supervision of professors Jesus Zurita Gabasa and Jesus Mª Pintor Borobia, from the department of Mechanical, Energetic and Materials Engineering, is working in a project to improve and optimise vibrating tables that are used in the agri-foodstuffs sector. The project is being done by the request of the company Tecnologia Alimentaria Urtasun from Navarre (Basque Country) , manufacturer of this kind of machinery.

The company Tecnologia Alimentaria Urtasun focuses its activity in the design, production, commissioning and control of the whole production lines for the food industry. That includes the production line of vibrating tables. These tables are the machinery used to transport fruits and vegetables. They are called vibrating tables, because they actually function by vibration, so that the product moves with small jumps through the table, so that it reduces the damage. That way, by operators located at both sides of the table or in a totally mechanised way, the damaged parts can be removed or the product can be selected or distributed.

The main problems of these tables are related to their vibrating character. These machines must vibrate, and the more they vibrate the better it is, because the product moves faster forward and they can transport higher amounts of load. However, that causes greater deformations, and as a consequence, there can be problems of rupture or fatigue due to the presence of oscillating loads. And that causes a damage, which is accumulated in the material.

Validated virtual model
The researchers have developed a theoretical model for the company Urtasun, based on the simulation for finite elements, which allows characterising the dynamic and structural behaviour of a model of a vibrating table to be used in the food industry.

This work has been carried out in the test bench for fatigues and vibrations of the University.

Actually, they are developing a knowledge tool that allows optimising the machine. In addition, they believe that it would be interesting to work on the introduction of new materials and new technologies, which would allow, among other objectives, automating maintenance tasks for this kind of machines. For example, providing the machine with devices that allow knowing their state by recording a series of parameters. In those cases, the company Urtasun, via modem, could know the operating state of their machines, regardless of where they are installed. And that is very important, if we consider that the 40 % of the turnover of this company derives from export.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
