Temperature Monitoring for a Coffee Roaster
Continual Temperature Monitoring and Alarming for Your Business
CHESTERLAND OH - CAS DataLoggers recently provided the temperature monitoring system for a small coffee roaster producing home-brewed blends in the back of his small storefront. Original flavor creation required repeated experiments with green coffee beans sourced worldwide, poured into an industrial roaster and warmed to about 220°C (428°F) for a city roast with a good brown color that brought out the beans' flavor and acidity. To ensure a repeatable process and to get a detailed view of the roasting process to fine-tune new flavors, the owner wanted a user-friendly temperature monitor with wireless communication for quick data collection. This device needed to be compact for installation in a small room and economical enough to fit into the store's modest budget. The owner also wanted alarming functionality to let him control the process whenever temperatures went outside the appropriate range.
The owner installed a Wireless Thermocouple Data Logger in his brewing room, tying it directly to the nearest side of the roasting machine. He then connected the logger to a Type K thermocouple probe placed inside the roaster along with the beans to continually monitor the high temperatures. As the beans roasted, this data was collected by a Wireless Base Station attached to the wall nearby. Operating on a lithium battery, the datalogger recorded temperature from a wide range of -199°C to +1300°C. Throughout the process, the logger's display gave clear indication of the roaster's current temperature so the owner could quickly and accurately check product consistency.
The thermocouple datalogger's customizable alarm settings alerted the owner whenever the roaster temperature went outside the particular brew's range, such as a city roast or full city, measuring and storing the data by registering to the base station which wirelessly collected its current readings during set intervals and monitored for user-set alarm warnings.
The temperature recorder's memory stored up to 16,000 readings, enough to record every second and still log 4 1/2 hours of data. Further, the datalogger's compact size made for an easy fit on the side of the roasting machine, and FREE user-friendly software was included with the wireless base unit for quick setup and configuration before the next batch of beans went into the roaster.
After the beans had finished roasting, it was easy to download all the data: the data logger wirelessly sent its data to the base station from up to 500 ft. away when unobstructed indoors, and the recorder downloaded the datalogger's readings at full logging capacity in just 2 minutes. Additionally, the owner could simply download the data logger's readings onto his office PC. This built-in wireless communication technology allowed him to view current readings and stored data anytime from anywhere (including from home), presented in graph display or exported to other programs.
The brewer benefitted immediately from installing the Wireless Thermocouple Data Logger onto his roasting machine, collected using the Base Station. Now the brewer was able to oversee the roasting process to view and document the temperature profile and recreate it in the next batch. The system's ease of use made it easy to get started, with simple configuration and alarm setup. The temperature recorder was also cost-effective for the brewer's limited budget, giving his business wireless monitoring and alarming for an affordable cost.
