Temperature system regulates conditions in fruit cold storage units

CapTemp’s automated temperature recording system was developed for The CPF Group. This Group is an organization comprised of pear and apple producers throughout Portugal. The system continuously monitors and reports ambient temperature and relative humidity of fruit storage units as well as fruit pulp temperatures while in cold storage. 

Maintaining proper temperatures in cold storage units is imperative to prevent fruit deterioration and contamination from fruit flies. Too low temperatures can cause chill damage to fruit, resulting in spoilage.  High relative humidity also is necessary to maintain moisture.  The CapTemp temperature recording system ensures the cold storage units maintain ideal conditions for different fruit lots.  In addition, monitoring of fruit pulp temperatures enables CPF to extend the life of the fruit while performing heat treatment to fruit lots in response to phytosanitary requirements for export to certain markets such as Colombia and Mexico.

CapTemp configured a temperature recording system for remote monitoring and reporting of storage room and pulp fruit temperatures that includes its own digital temperature sensor (TH-3-Temp OW) and perforation sensor (TH3-Temp PT 100).  The sensors are in four points of the cool chambers and within the pallets containing fruit boxes.  While the digital temperature sensors extract data on room temperature, the perforation sensor provides an output on temperatures within the interior of the fruit.

The CapTemp system can optionally support additional sensors and meters such as water and energy meters to monitor additional parameters related to operations.  Data collected from different cool chambers and fruit is centralized at the control room so operators can view parameters for the entire operation.

CapTemp’s solution is fully complaint with the European standard EN12830, which was adopted in November 2018. EN12830 applies to temperature recorders for the transport, storage and distribution of temperature sensitive goods, and tests performance and suitability.
