Dynamic Imaging - Introduction Dynamic Imaging operates on the basic principle of capturing a real time view of a process, to either support an operator in making process related decisions, or to feed image analysis software which performs specific process measurements A typical Dynamic Imaging consists of 3 common hardware components; Viewing Medium Imaging Sensor Process Lighting Canty’s unique glass / metal fusion technology forms a 1 piece construction component, capable of withstanding high process pressures & temperatures Canty’s systems use Gigabit Ethernet technology, incorporating high colour sensitivity, and are designed specifically for process vision applications, and can be utilised with a variety of lenses (micro, macro, standard) depending on the specific application Canty’s background is in vessel / process lighting, with over 40 years of experience in the field. Each light system uses either halogen or LED technology, and is specifically designed to suit the imaging sensor type it is combined with JM Canty, Inc. · Buffalo, New York · Phone: (716) 625-4227 | JM Canty, Ltd. · Dublin, Ireland · Phone: +353 (1) 882-9621

Crystallisation Monitoring - Manual Viewing Unique Manufacturing Process Our unique glass recipe (BoroPlus™) is heated to it’s molten point and poured into the centre of a metallic ring The BoroPlus™ glass fuses / bonds to the metal and is slowly cooled The metal compresses on the glass due to it’s higher coefficient of expansion, putting it under radial compression By fusing glass to metal, a high pressure, high safety, hermetic seal is formed, resulting in a one piece construction Fuseview™ sight glass JM Canty, Inc. · Buffalo, New York · Phone: (716) 625-4227 | JM Canty, Ltd. · Dublin, Ireland · Phone: +353 (1) 882-9621

Crystallisation Monitoring - Manual Viewing Tempered sight glasses, cannot be fully tightened in place for fear of cracking the window and ruining the batch. Therefore, there is not a full vacuum seal which causes leaks, and means more energy is required to boil the liquid. By using a Fuseview™ the user is tightening on metal so cannot over torque and damage the window. A full seal is maintained, and so a full vacuum is achieved, meaning huge energy savings JM Canty, Inc. · Buffalo, New York · Phone: (716) 625-4227 | JM Canty, Ltd. · Dublin, Ireland · Phone: +353 (1) 882-9621

Crystallisation Monitoring - Manual Viewing The energy required to heat a volume of liquid from one temperature to another can be calculated using the formula Q=mCp(T2-T1) Q = energy required T1 = starting temperature m = mass T2 = finishing temperature Cp = specific heat To heat 1 litre of water from 20°C to a boiling point of 100°C (ambient; 14.7 psi) Q=1(4.186)(100-20) = 334.88kJ / 0.093kWh per litre To heat 1 litre of water from 20°C to a boiling point of 80°C (vacuum; 6.9 psi) Q=mCp(T2-T1) Q=1(4.186)(80-20) = 251.16kJ / 0.070kWh per litre   To heat 1 litre of water from 20°C to a boiling point of 60°C (vacuum; 2.9 psi) Q=1(4.186)(60-20) = 167.44kJ / 0.047kWh per litre JM Canty, Inc. · Buffalo, New York · Phone: (716) 625-4227 | JM Canty, Ltd. · Dublin, Ireland · Phone: +353 (1) 882-9621

Crystallisation Monitoring – Crystal Size (Sugarscope™) Return on Investment: With the annual increase in the production of large grain sugars, it is critical that we optimize our Pan Yields, Crystallization Times and Utilities in producing these products. By having operator’s continuously view / measure the crystallisation process, it is felt that the below can be achieved;   Reduce boiling times by 33% thus increasing number of batches Overall increase yield by 10% (250,000 lbs/day) Reduction in annual water / steam usage by 33% (3,200 gals to 2,110gals per strike, 545,000 gals/4,523,500 lbs. of steam per year) Increasing by 250,000lbs/day, would save ½ a shift of processing labour per week, which is 9 less melt days required per year. This gives a saving on staff payments of ~$22k per year. Reducing water / steam usage by 4,523,500 lbs would give a saving of ~$30k based on current energy costs. Total savings for 1 year: ~$52k Estimated total procurement / installation cost: ~$25k per unit (x2) Payback duration: <12 months JM Canty, Inc. · Buffalo, New York · Phone: (716) 625-4227 | JM Canty, Ltd. · Dublin, Ireland · Phone: +353 (1) 882-9621
