There is an increased focus today on improving nutrition. Farm to table is an option many are considering to deliver fresh, pure food for consumption by their families. In this push to deliver better food for consumption, the process of canning, which dates back centuries, is also undergoing a revival.

The great thing about canned produce is that it’s packed within hours after being harvested and the process of canning locks in all the ripe flavor and optimal nutrients.

According to a report from Grandview Research, the canned food market will be worth around $22.23 billion by 2025.

Demands for more vegetables sourced from local farms and an increase in consumption of affordable, convenient food options, are all adding to an uptick in the canning market.

One step that is critical in the accuracy of the preservation process in canning involves the use of sensors.

First, let’s take a look at how the canning process typically works.

  • Food is placed in jars or containers.
  • Air is removed from jars.
  • Cans are heated to a set temperature to keep food from spoiling.
  • A vacuum seal is formed to keep the cans safe for shelving until used.

Whether the canning process is happening in a large facility or you have set-up a smaller process for canning foods, accuracy and precise measure are key to a successful outcome.

The heating and cooling processes involved in canning don’t just lock in the flavor, they also safeguard the food so it remains safe to eat for its entire shelf life.

Temperature & Pressure Sensors Are Critical to the Heating & Cooling Process

Sensors used in the process ensure these steps happen and include the use of temperature and pressure sensors. These should detect with accuracy the temperature distribution at different locations in the can as well as the pressure of the fluid and contents inside the vessel. Weight sensors and liquid level sensors can also be added to the line-up to assure that the same amount of product is being added to each can.  These steps are the only way to eliminate possible contamination and stop the growth of harmful bacteria while also improving productivity and quality.
