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

15.11.2002


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: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
