Squirrel Data Logger ‘Clamps’ Down on Sugar Loss

Grant SQ2010 Portable Data Loggers

CHESTERLAND OH—September 28, 2011

CAS DataLoggers recently provided the data logging solution for UK sugar company British Sugar, which was searching for a high-tech way to prevent their stock of sugar beets from deteriorating in storage while waiting to be processed into white sugar bound for kitchens and tables around the world. Harvested sugar beet remained alive and as it respired, converting sugar into carbon dioxide and water, it generated heat. If the temperature inside a mountain of sugar beets—called a clamp –rose above 10°C (50°F), there was a dramatic increase in sugar loss. The crop could be stored for 60 days before processing, but if poorly stored, sugar beets could lose up to 60% of their sugar content before they were processed, and whole clamps could lose 1% of their sugar content a day. Additionally, while the inside of a poorly maintained clamp could be generating considerable heat, the surface exposed to the elements could be frozen, leading to a further loss of sugar content. The goal was to establish and maintain a well-ventilated, cool clamp in a hostile and often exposed farmyard environment where temperatures could fluctuate between 15°C (59°F) during the day to -10°C (14°F) at night. Seeking to minimize sugar loss and maximize their product quality, British Sugar needed a highly-accurate data logging solution which could easily be inserted throughout a clamp to help them experiment with innovative storage techniques.

The customer installed 6 modified Grant Instruments Squirrel 2010 Portable Universal Input Data Loggers into widespread areas of its test clamps. A powerful yet portable datalogger designed for versatility and ease of use, the Squirrel 2010 featured 4 to 8 universal analog inputs measuring current, voltage, resistance, and temperature, along with 8 digital inputs. 2 alarm outputs and 2 pulse counter inputs were also standard, with measurements made at a basic accuracy of 0.1% and an operating temperature of -20°C to 65°C (-4°F to 149°F). The Squirrel’s handheld, compact design made for a truly portable solution for employees scaling the clamps, and had an extended battery life for long periods of unattended logging. Large amounts of experimental data were collected, with each logger storing up to 1.8 million readings. The economical Squirrel 2010s were built to withstand the worst possible conditions, including the wild temperature fluctuations in the exposed farmyard and heavy rains. Regardless of the weather, the Squirrels provided British Sugar researchers with detailed and precise temperature measurements every hour.

The Squirrel 2010 portable loggers were infinitely adaptable and simple to operate. Easily programmable via four integral push buttons and large graphical display, the Squirrel dataloggers were capable of many routine data logging tasks, including more demanding applications requiring up to 10 readings per second on one channel. The temperature data could be instantly downloaded onto a conventional PC via USB connectivity in an easy-to-analyze graphical form. Ethernet or RS232 communications options were also available.

British Sugar looked closely at how sugar loss was affected by temperature and tested several new methods of controlling temperatures throughout the beet clamps. The data from the Squirrels enabled researchers to experiment with a variety of plastic and polyfelt materials to insulate their clamps from the worst of the weather and with building effective ventilation shafts directly into the clamps to keep them cool.

Each Squirrel 2010 data logger came equipped with free Squirrelview software to enable company researchers to import data onto a PC and display detailed graphs or print them out for record purposes. Squirrelview’s intuitive, user-friendly, spreadsheet style interface allowed quick set-up of the data loggers, speedy data downloads and direct export to Excel. Upgrading to SquirrelView Plus gave additional benefits such as graphical data analysis and advanced reporting options.

British Sugar realized several major benefits after installing the portable Squirrel 2010 data loggers in their sugar beet storage grounds. The portable and compact dataloggers were essential for recording highly accurate measurements throughout the clamps’ interior and exterior, and their proven durability kept them recording despite the harsh weather. Following the successful temperature-control experiments, more efficient storage methods were developed resulting in extending the amount of time the company had to process the annual crop from 110 days to 150 days. Those extra 40 days greatly enhanced the cost-effectiveness of the process and gave the company a big advantage; across Europe, sugar processors were still locked into processing their stores of sugar beets within 110 days to avoid major deterioration of the crop. Furthermore, the data logged on the Squirrel dataloggers provided the basis for advice to farmers across the country on the most effective methods of storing sugar beets before processing.

Patrick Jarvis of British Sugar remarked: “This research is vital, not only giving us a competitive edge, but also ensuring that British farmers get the best return from their beet crop. The Squirrel dataloggers are extremely robust and accurate, and the data they provide is easy to download and easy for our field researchers on farms to analyze. The Squirrels are playing a vital part in keeping us ahead of our European competitors.” The Grant Squirrel 2010 product page can be found here.

    You actually make it appear so easy along with your presentation but I in finding this matter to be actually something that I feel I would never understand. It sort of feels too complicated and extremely huge for me. I’m having a look forward in your next submit, I’ll try to get the grasp of it!
