CESMEC always thinking in its clients has implemented wireless thermocouples in order to provide a more flexible service, efficient and one that allows to provide its clients high quality products to the market.
Validation services of thermal processes are performed with thermocouples of copper/constantan that measure temperature variations almost instantaneously with adequate calibrated potentiometer. These thermocouples are installed in the package, in the zone known as cold point, meaning the zone where heat takes more time to be produced compared to the rest of the package that contains the food.
Traditionally, suppliers of these services get measurements done using Cabled Thermocouples. Today, due to the great development of wireless technologies or WiFi there are innovating methods or techniques to perform thermal validations which consist in wireless systems that have incorporated ultimate technology to program sensors.
The advantage of these services is they give a major flexibility to perform studies because they can be used in all kinds of auto password and also its use in ground is far more expedite avoiding installation of too many cables and adaptors by not using electric equipment in humid environment.
They referred to wireless Copper/Constantan thermocouples which allow fast measurement of temperature variations in cold point of a can product, with a precision of 0.05ºC. These loggers can operate under extreme conditions with no loose of captured data; also they can tolerate temperature between -50 °C to +150 °C. Each logger can store 30.000 data and is able to retain readings after a failure on the internal battery.
This new technology due to its versatility is being used in industry preferentially in order to validate thermal processes of: fish can food such as: salmon meat, salmon pastry, mollusk and fish in general; as well as frozen Hydrobiological products for cooking. Authority demands certain requirements which must be done related to: cooking must assure that the product has been put down al least to 90ºC for a 90 seconds period.
These thermal studies are applicable to food and pharmaceutical industries. Within food industry they can be used to validate: pasteurization industry, cooking, helicoid boilers and coolers, convective furnaces, freezers, smokers. On the other hand, in pharmaceutics its use is applicable to sterilization processes, liofilization, chamber stability, cold storage, sterilization of peroxide of hydrogen, incubators validation or multiple applications, CESMEC, through these technologies offers services in all the country, providing a valuable tool for the industry regarding Food Security issues and accomplishing requirements of European Union FDA and others.
