Acceleration Assessment During Mechanical Harvest of Grapes Using a non Commercial Instrumented Sphere
2017
The use of the harvesting machine for grape wine has the limit of the production of must coming out from the detachment of the berries that could reflect negatively on the quality of the final product. It depends on many factors including grapes variety, ripeness and frequency of the harvesting machine shakers. The shaking frequency generally adopted is the one that achieves the maximum harvest efficiency, that means high work capacity and low grape juice production. In this paper, the authors present a new system to measure the accelerations received by grapevine during mechanical harvest with the aim of evaluating the influence of the shaking frequency on the quality of the must obtained.…
Influence of the pressing system on pomegranate juice physical-chemical properties
2017
Pomegranate juice has many health properties as the fruits contain anticarcinogenic, antimicrobial and antiviral compounds. Its consumption has greatly increased throughout the world in recent years due to the potential of its different components, polyphenols and anthocyanins among all. Many studies have been performed on the pomegranate juice yield demonstrating its influence on the organoleptic and physicochemical properties of the juice. Commercial pomegranate juice production involves pressing fruits procedures. As a consequence, there is a need to investigate the pressing machine types and optimization in order to achieve juice yield and enhance its health properties. The aim of this …
A multi objective approach to short food supply chain management
2017
Conventional supply chains, involving several stages and various intermediaries, are affected by some well- known forms of inefficiencies and drawbacks. Besides the increase of market price consequent to multiple marginalization, such supply chains generally suffer of significant post-harvest losses and product waste. In this context, short food supply chains have been recently proposed as different systems capable of delivering higher quality products while promoting sustainability and efficiency. Across the EU, a growing number of consumers choose to buy food products on local farmers' markets, associating local products with higher quality standards (freshness, nutritional value), health…
Noise risk assessment in a modern olive oil mill
2017
High levels of noise usually occur in olive oil mills because of the machines used to extract olive oil with a continuous plant. In Italy Law Decree 81/2008 defined the requirements for assessing and managing noise risk, identifying a number of procedures to be adopted at different noise levels to limit workers exposure. This study aims at evaluating the equivalent and peak noise levels inside a modern oil mill plant area in Sicily, south Italy. Twenty measurement points were identified inside the oil mill plant area where the machines for olive oil extraction were located (about 200 m2). The instrument used for the measurements was a precision integrating portable sound level meter, class …

FRUIT 85, UNA TRATTRICE POLIVALENTE
2013
La macchina, chiamata Trifrut 85 HP, è caratterizzata da un ridotto sviluppo in altezza tale da permettere l’adozione di un arco di protezione fisso nonostante l’impiego sotto chioma.
Un intervento genetico che accresce la resa del mais
2018
Aumentando con interventi di ingegneria genetica i livelli di un enzima che in alcune piante – tra cui il mais – è centrale per l’efficienza della fotosintesi si può ottenere un incremento del 15 per cento delle rese agricole anche in condizioni di relativa siccità.
