Automation is Proving to be a game-changer in Food safety!

Nov 16, 2018

Have you ever wondered if the food we eat is safe? If you have, how can you ensure it is safe?

One of the most reliable and important methods to guarantee proper food safety is accurate and reliable temperature monitoring. 

Is it Automated?

With today’s technology, it is possible to track the correct temperatures and humidity wherever you store raw materials and produce. This helps to prevent the stock from getting spoilt and ensures its longevity and safety.

The automation of temperature monitoring & control has enabled the maintenance of food safety even during transit, processing, and storage, and provided critical information immediately and wirelessly with alarm notification and electronic data records.

Records should prove that critical temperatures were met in every phase of the operation, from food manufacturing to retail. This is absolutely essential to satisfy regulatory requirements.

Modern digital data-logging equipment will note down the temperature automatically, along with all other process parameters. This data can be logged and stored, meeting the requirements of the regulatory agencies.

It also helps senior management get a handle on the temperature status faster than before.


Now, it is possible to instantly access temperature data, remotely, and the alerts can be sent immediately if there is an issue. Since the data is stored digitally, paper charts are not required, making the data more accessible.

Temperature instrumentation also offers more flexibility today. A fixed-location sensor or convenient handheld devices are used that offer internal storage or wirelessly connect to external storage, either on-premises or in the cloud.

Using both direct contact and non-contact temperature sensors can improve temperature control in applications where internal product temperatures are more critical than external surfaces.

Sensing elements are chosen in such a way that they are pretty stable to work in different temperature ranges and in contact with various solid, liquid and gaseous environments and are so fast (in milliseconds!).

Why Are These Sensors Used?

  • To check the temperature of food exiting a flash cooler
  • To measure the temperature of cereals at the exit of puffers and flakes
  • To check the temperature of soup as it’s cooked in large vats—as well as liquids and vegetables in plastic or glass containers
  • To measure the temperature of products inside ovens and roasters.

How About The Food In Transit?

Temperature monitoring is necessary during transit too. Various data-logging approaches, from fixed devices inside trailers to portable units and even non-electronic, thermal-indicating temperature strips are used. These ensure that transportation practices reduce safety risks by unhygienic sanitary transportation, including temperature control.

Electronic data loggers help to collect temperature data during a shipment and determine if any temperature excursions happened during transit that could affect the quality or food safety of a shipment.

Chemical temperature indicators provide a cost-effective and easy way to track if a temperature breach has occurred during product shipment.
