Regulations like HACCP, FDA or ISO define temperature controlling requirements for all steps of handling and processing of sensitive food. Compliance to HACCP in food industry is therefor of most importance.

Background                                                                                                                                                                                                                  IONIKI S.A. is one of the leading vertically organized production units for frozen dough and pastry products in Greece. During production processes, IONIKI was measuring temperature data on the outside of their pastry filling mixers. To comply with HACCP standards in the food industry, IONIKI had also to measure the temperature inside the mixer which contains fillings for frozen food products. Manual data collection is simply impossible during production. To ensure that a certain temperature level had been reached in a rotating mixer, wireless data collection was the best solution. The challenge was to install the battery driven wireless sensors on the rotating section of the mixer, of which parts need to be taken out regularly for cleaning.

Solution                                                                                                                                                                                                                          IONIKI S.A. selected therefor the reliable wireless device networking solutions SenzaNET from E-Senza for meeting this challenge at a very reasonable cost and effort. E-Senza`s partner in Greece, BitLogic Industrial Automation, solved this problem by using the wireless temperature sensor SenzaBlock SB110-T. The SB110-T includes a 24-bit analog to digital converter for accurate temperature measurement of PT100 ohmic resistance temperature sensors. SenzaBlock was mounted on the upper part of the mixer; the PT100 sensor can be placed at the right depth and easily be removed for cleaning.

When activated, the wireless sensor automatically samples, logs and transmits all temperature data in user-configurable intervals. They communicate to a SenzaGate SG131, gathering all the data and being responsible for reliable communication in the network. An Ethernet connection is used to transfer data to a central server system, where the wireless monitoring software SenzaWMS manages, visualizes and configures the network, provides monitoring information and allows for alarming and data export.

Benefits                                                                                                                                                                                                                       With the wireless temperature monitoring system of E-Senza IONIKI S.A. can now monitor product quality more accurately and ensure compliance with HACCP standards at reduced labor costs.
