1 Exotherm 2000 Dynamic Crystallization of Fat and Fat based products A Complete Solution Bench top instrument made of : - Exotherm 2000, the main part where the product temperature and sheare are precisely controlled via an electronic interface and a computer. Regulation of temperature is ensured by electric resistance and cooling bath - Computer - Cooling bath 20 C to +100 C A robust design ensures : - Precise control of temperature and shear - Very sensitive temperature and torque readout - Practical handling design - Extremely low gap between stirrer and beaker wall (less than 0.2mm) SYSTECH ANALYTICS SA 1/10

2 Sample beaker - Sample volume 200 to 700 ml - Made in aluminium with special coating for long life and effective heat transfer - Inner graduations every 100 ml - Equiped with 4 temperature sensors PT100 1/10 DIN - Conical shape in order to ensure perfect wall to wall contact with the cooling/heating cell - Only one electrical and waterproofed connector for an easy cleaning - Central temperature probe with two sensors in one - Two different heights of measurement - Inner marks each 100 ml - On the left of the central probe, a special temperature sensor is visible. It is used to measure the temperature of the product near the wall. Dedicated temperature sensor View on the waterproofed connector SYSTECH ANALYTICS SA 2/10

4 Closer view on optical & ultrasonic sensor All sensors can be easily removed for cleaning Thanks to laser soldering the ulstrasonic mirror is precisely placed and holded Cloud Point optical sensor Ultrasonic sensor SYSTECH ANALYTICS SA 4/10

5 Software outlook A complete set of paramaters can be programmed SYSTECH ANALYTICS SA 5/10

6 Typical measurement curves Software highlights : Temperature in the center of the sample Temperature profile Torque Light (cloud point) - Very long measurement time (up to 24h or more). - All measurement parameters can be set in a method (no limited numbers of methods). - Parameters of the temperature control s loop can be easily modified by the user. - Automated saving of measurement. - Exportation of methods and measures to Excel (text files) - All parameters of the ulstrasonic equation are accessible. - Easy and precise calibration of temperature and ultrasonic sensors. - Alarm and automatic stop on stirrer motor. - Digital filter on torque measurement (all filter parameters are accessible). - Temperature an motor s speed profiles can easily be set in the methods. - Sampling time can be modified from 1s to many minutes. Different sampling times can be programmed during one measurement. Very usefull to lower the size of the Excel files and to keep high resolution on particulary interesting parts of the measurement. - Zoom functions on the graphics. - All measurements are saved under «Access Data Base» format. - Measurement can be put on «standby» mode. Very usefull to change the method parameters during measurement without a complete restart. SYSTECH ANALYTICS SA 6/10
