Una delle principali caratteristiche è la sua alta velocità di campionamento della Forza. FA Plus può registrare un valore in 5msec (2000 valori / sec.), per cui è adatto soprattutto per prove con scosse (shock test) in cui i valori sono soggetti a cambiare improvvisamente. FA Plus può essere collegato con vari tipi di celle di carico. La separazione delle celle di carico dall’amplificatore è un’ottima soluzione soprattutto se utilizzata in aree di lavoro pericolose o anguste. L’FA Plus può anche essere collegato con la vostra macchina di prova o robot. |

La Lloyd Instruments ha sviluppato per la versatile macchina per prove sugli alimenti TAPlus un nuovo dispositivo per testare la collosità dei fogli di pasta cotti, come ad esempio le lasagne. Essendo le Lasagne un piatto estremamente popolare, presente sia come piatto pronto nei supermercati sia come piatto preconfezionato per pub e bar, la trama del prodotto finale è estremamente importante. La collosità è legata al contenuto di amido del foglio di pasta, che a sua volta è legato alla temperatura e al tempo di cottura. Misurare la collosità della pasta consente di ottimizzare questi parametri. Il foglio di pasta cotta è montato tra il piano di base della TAPlus e una piastra rettangolare contenente un foro rettangolare. Una sonda penetratrice rettangolare abbinata al dispositivo è utilizzata quindi per applicare una forza di compressione uniforme sui fogli di pasta attraverso il foro. La forza necessaria per ritirare la sonda viene misurata dalla TAPlus. La sonda può essere in contatto con il foglio di pasta per un tempo predefinito prima del ritiro, se necessario. I test possono essere completamente configurati e controllati utilizzando il software di acquisizione dati NEXYGENPlus. Oltre ad una completa libreria di standard di settore per le prove sugli alimenti (tra cui la viscosità) e per altre tipologie di prove, il software NEXYGENPlus è caratterizzato da una enorme gamma di altre funzioni. Queste includono la creazione di prove determinate dall’utente, la raccolta dei dati, l’elaborazione di relazioni e l’esportazione dei dati del test, l’acquisizione anche di video e foto, funzioni di sicurezza permettendo, per i dati imputati e successivamente processati dal sistema, la tracciabilità a ritroso al dato originale, ed inoltre prove di automazione e personalizzazione. |

Measuring the Eating Quality of Meat
Article published in Food Marketing & Technology, February 2008 Issue, pages 30-32 by permission of Dr Harnish International Publications Uniformity and enhancement of meat eating quality is seen as an important factor in the sustainability of the Scottish (and UK) red-meat sector, in securing increased high-end market share locally and internationally. A number of factors affect meat eating qualities, both in terms of the way the animals are reared and at he the processing stage of production. Several studies have shown that the highest ranked eating quality characteristic is meat tenderness. Subjective measurements of this characteristic are made by structured taste panels. Objective measurements have been made traditionally by texture analysis methods using the classic 'Warner-Bratzler' (WB shear force technique. The efficiency of red meat production and marketing could be improved by better techniques for measuring carcass and meat quality and the Scottish Agricultural College (SAC) has recently started a Scottish Government-funded research programme investigating novel measures and predictors of meat quality, which involves comparing a range of techniques for improve measurement in beef and lamb. These include a new shear force test, the rapid Slice Shear Force (SSF) test using a TAPlus texture analyser from a British supplier [Lloyd Instruments] as well as near infrared reflectance and computed tomography measurements on meat samples.

The huge popularity of burgers from fast food outlets, pubs and at home, together with competitive pricing means that the composition of burgers can vary significantly, from 100% prime ground beef to poor-quality meat containing a high percentage of fat, bulking agents, salt and other additives. Texture analysis of uncooked patties using a new test jig for the Lloyd Instruments’ TAPlus texture analyser provides an objective measure of the burger consistency. The burger is placed on a support plate containing a 27 mm diameter hole, which is mounted on the TAPlus base table. A cylindrical probe, which opens out in an inverted cone shape with a flat end of 25 mm diameter, is used to apply force to the burger. The new test jig can also be used for testing reformed cooked meat such as ham and spam. The TAPlus texture analyser is an easy to use, cost effective solution to evaluate the textural properties (compression, shear, extrusion, puncture, hardness forces etc) of a wide range of products at all stages of manufacture. It can perform rapid, detailed texture profile analysis (TPA) for applications up to 102 kgf (1 kN, 225 lbf). For automated testing and analysis of results, the TAPlus can be used with NEXYGENPlus data analysis software. NEXYGENPlus provides a comprehensive library of industry-standard texture analysis tests to internationally recognised standards. NEXYGENPlus also features complete test wizards for tension, compression, tearing, peeling, friction and flexural tests. |

Lloyd Instruments announces the launch of the Davenport™ MVPlus Melt Viscometer at K’2007. This new instrument, which uses a unique solvent-free method for the measurement of intrinsic viscosity (IV) of PET, is available in stand-alone or computer-controlled versions and offers a number of key benefits. In addition to its obvious environmentally friendly operating method, its compact construction occupies significantly less bench space than earlier models and makes it easier and quicker to load samples. The MVPlus is very user-friendly and features an integral nitrogen regulation valve so that nitrogen pressure can be controlled at the instrument itself. The MVPlus continues to use the unique solvent-free method of previous models for routine testing of the melt viscosity (MV) and intrinsic viscosity (IV) of PET. Molten PET is extruded through a calibrated die by nitrogen gas under pressure and the LVDT probe movement against time is recorded and displayed. The system measures the optimum flow rate and calculates melt viscosity and intrinsic viscosity using a patented method originally developed by ICI. The procedure used ensures that reliable, accurate and repeatable results are easily obtained and checked against standard polymers. Alternative methods require the use and subsequent disposal of toxic solvents with all the associated costs. Using a method that does not require solvents also means that there are also no adverse effects on the environment. The stand-alone version features a backlit LCD, which displays both instructions for the test and the results calculated at the end of the test. An RS-232 interface allows connection to a computer for fully automated control using the powerful NEXYGENPlus V2.0 materials control and test software, with its comprehensive range of standard tests and other facilities and newly introduced Word™ report generator. Polymers can be tested at virtually all stages of the process: incoming resin, powder, dry granules, molten polymer, pre-forms, bottles, films and even recycled material to eliminate scrap. Rapid testing at the different stages can be carried out using ancillary equipment for controlled sample collection and preparation. Other products in the Davenport range include melt flow indexers, HDT/Vicat thermoplastic measurement instruments, density columns and falling dart impact testers for testing plastic film. |

Lloyd Instruments has developed a special jig for easy determination of peel strength of the aluminium foil on contact lens blister packs. Designed for use primarily with the low force LFPlus single column materials testing machine, the jig features a self-adjusting sliding bed for true 90° peel tests. The jig has been engineered for use with two contact lens blister packs, each containing individual lenses in a solution. One lens pack is clamped in the upper instrument grip, whilst the other is clamped and fitted into a special mount in the jig’s sliding baseplate. As the test machine’s crosshead is driven upwards, peeling the foil on the lower blister pack, the baseplate slides horizontally, to ensure that the peel force is always applied vertically. Peel strength is an important parameter to be measured for contact lens packages. Too high a strength and the blister package is difficult to open and there is the risk of a sudden opening resulting in the lens and fluid being accidentally ejected. If the peel strength is too low, there is a chance that the foil lid could be detached accidentally, for instance when carried in a bag or pocket, with loss of fluid and damage to the lens. With material testing and force measurements up to 1 kN (225 lbf), test speeds from 0.05 to 1270 mm/min and accuracy greater than 0.2% the LFPlus materials tester is ideally suited to peel test applications of this type. Tests can be fully automated through the addition of the new NEXYGENPlus materials testing software. |

Texture analysis has important implications for quality in potato products, says Lloyd Instruments. Potato products can be mashed, boiled, roasted, fried, baked and be as diverse as potato salad through to chips. Each has its own texture characteristics and it is important to be able to make reproducible, scientific measurements of these parameters. Texture testing is a well-established technique for evaluating the mechanical and physical properties of raw ingredients. Read the full article here: The Perfect Potato? |
