How the food industry is taking advantage of automated monitoring to optimise working procedures and decrease workloads

When it comes to the food industry, no matter which area a company works in, food safety is always a major concern. The sheer scale of end-customer demand, coupled with strict time restraints, puts a huge amount of pressure on the food industry to ensure all produce is carefully monitored and regulated from farm to fork. Practically every point of the process, throughout production, preparation, storage and transport, has potential danger areas regarding spoilage through mismanagement or poor temperature regulation.

Monitoring temperature is a particularly important part of this process. Incorrect climatic conditions can have devastating consequences, and businesses often leave themselves at risk of incurring needless costs should there be a power cut, or system malfunction. This can lead to wasted stock or worse; a legal dispute.

Such costs can be detrimental to both production and reputation (should the tainted stock be distributed) and will ultimately have a negative effect on profit margins.

Within the food industry more and more businesses are opting to use automated temperature monitoring. For certain applications simply using a data logger and noting down readings manually is sufficient, for instance building monitoring where there is no danger of damage to stock and you simply need the records for reference purposes. When dealing with climate sensitive stock though, as is more often than not the case in the food industry, using an alarm fitted system which monitors conditions continuously is fast becoming a necessary requirement. With such a system in place, if there is a problem, you will be notified immediately, so you are able to react straight away, before it is too late. This is particularly useful if you don’t have staff on site 100% time, which let’s face it, most companies don’t the have resource for.

When first introduced, whilst the logic and practicality behind this type of solution is somewhat undeniable, systems were very costly and the quality manager or person responsible for food safety simply couldn’t justify the cost. This has often proved to be the stumbling block for companies looking to move to an automated system, instead sticking with more traditional temperature loggers, and taking manual readings. To an extent this is understandable, “if it’s not broken don’t fix it”, right? Admittedly, in the first instance investment is needed for such a system. In the long run, however, it will likely save the business valuable time and manpower.

For example, if in the current regime a member of staff is required to go around and take checks at numerous locations, this is a needless additional task which could be used for something more productive. And of course, as mentioned previously, the overriding advantage of employing such a system is to act as a contingency measure and protect your operation in the event of a problem or system malfunction. This could end up saving money in the long run, on wasted stock, potential product recalls etc. Another saying comes to mind: “But we’ve always done it that way”. This has been described as the 7 most expensive words for any business; failure to adopt new methodologies can hurt a business in the long run.


The above video explains the advantages of an automated temperature monitoring system

What’s more, as technology continues to advance at an astonishing rate, such systems are now becoming available for a fraction of the cost when this type of system first hit the market. Testo’s Saveris 2 for example offers a fully automated temperature monitoring system from under £100 with no additional costs for software. Therefore, it doesn’t cost as much as you’d think to ensure your peace of mind.

5 advantages of using a temperature monitoring system

There are a number of ways to keep track of indoor climatic conditions. The most frequently used of these is the use of a small, basic data logger. For certain applications a data logger is sufficient, for instance building monitoring where there is no danger of damage to stock and you simply need the records for reference purposes.

If you have climate sensitive stock however, particularly if you’re not going to be on site 100% time, an alarm fitted system which monitors conditions continuously will benefit you massively.

There are a number of advantages to using a temperature monitoring system, below we have put together 5 key factors why they have been proved such an effective method for keeping conditions stable.


1) Save money

Employing a temperature monitoring system will save you money in the long run, on wasted stock, product recalls etc. If there is a potential problem, you will be notified immediately, before it is too late.


2) Efficient and convenient

All reports are put together for you automatically so you don’t have to lift a finger. These will be collated and sent to you each morning via email.


3) Accessible from anywhere

Reports can be sent directly to you via email, SMS or App so you don’t need to waste time checking each individual logger (or even going to the site for that matter).


4) User friendly

Some monitoring systems require time-consuming installation and maintenance but with a wireless system such as testo’s Saveris 2 it is very simple to get set up and started.


5) More affordable than you think

With testo Saveris 2 systems available from just £89 (ex vat.) it doesn’t cost as much as you’d think to ensure your peace of mind.


All in all temperature monitoring systems offer a low cost but reliable solution for those who need to monitor indoor conditions continuously. We hope the 5 advantages listed above go some way in helping you to find the solution that best suits your requirements.

Why Climatic Conditions are so Important to Bakeries

Strict demands are made in the production of bread and bakery products. Customers expect immaculate product quality as well as reasonable prices, whilst authorities demand food-safe ambient conditions. Whether in raw material storage, in the preparation of dough or during the baking process – strict conditions must be adhered to with regards to temperature and relative humidity.

Keeping baked produce at the wrong temperature can have devastating effects

Continuous monitoring of ambient data is hugely important throughout the food manufacturing industry, and none more so than when producing bakery products. Baking errors and contamination by health-damaging microorganisms must be avoided, whilst energy efficiency and economic viability is of the utmost importance.

Examples where measurement of ambient climate values is essential include:

  • during the storage of raw materials in refrigerated and deep-freeze rooms
  • in maturation and cooking chambers
  • during the cooling of finished baked products (monitoring of coolant water temperature in heat exchangers)
  • in cleanrooms which protect from mould and spores, allowing germ-free packaging
  • during the transport of bakery products to the branch stores and points of sale


How can bakeries keep on top of this?

Employing a climate monitoring system such as testo’s ‘Saveris‘ gives companies a way to continuously monitor conditions throughout the production process. It monitors the temperature and humidity of a storeroom for instance, then documents all the findings automatically. The input of limit values ensures that the legal hygiene standards are always maintained. If any deviations were to occur, the system immediately triggers an alarm.

Storing baked products in the correct conditions is essential

The monitoring system gathers all warning reports along with the ambient data from the various measurement sites and summarises them into clear reports, making them centrally available to those responsible for quality and the process.

The adherence to legal hygiene standards is also optimally supported: Saveris fulfils the requirements of EN 12830, and conforms to HACCP (Hazard Analysis and Critical Control Points). With testo’s Saveris, you always have your process and storage rooms under control.


What makes Saveris so effective?

Perhaps the biggest advantage of employing a Saveris system is you can monitor the conditions of muiltiple rooms or vehicles at the same time. This means you an be certain your produce has been stored properly throughout the process chain, and all results are collated into one central place.

It is a comprehensive, yet easy-to-use system. In stationary operation, the transfer of the measurement data takes place via wireless and/or Ethernet connection to a base station. This documents and monitors all measurement data.

Data is available to view and settings can be configured on networked computers. Individual user access permissions can be assigned according to whether the user requires full administrative or simply viewer rights. In addition, data is also available to view via a web browser, so information is available 24/7 via any web enabled device.

If limit values are exceeded, a whole range of different alarm options, such as SMS/e-mail alarm or alarm relay are available. Remote alarms can even be given when the system is not connected to a running PC. The base is the heart of testo Saveris and can save 40,000 readings per measurement channel independently of the PC. This corresponds to around one year of memory capacity at a measuring rate of 15 minutes.
