The TuberLog Electronic Potato identifies damage and bruise causes in all types of potato handling machinery. 

The operator watches the TuberLog passing through a machine and its Bluetooth technology links to an Android app to help immediately indicate sources of impact. 

TuberLog enables immediate improvements to quality problems in potato production. 

TuberLog assists with the prevention of economic losses caused by bruising. 

How does TuberLog work?

  • TuberLog is an acceleration measurement logger embedded in a synthetic shape that mimics the size, shape, density and movement characteristics of a ‘ware’ potato.
  • TuberLog records impacts while moving with real potatoes during harvesting and processing and locates damage and bruise-causing parts of machinery.
  • TuberLog transmits impacts instantly by Bluetooth, visually on an Android tablet or smartphone and audibly in the device’s headphones, so the operator can immediately locate the impact source.
  • TuberLog records and stores impact and temperature values. The data is transferred by Bluetooth or USB to a PC or laptop where it can be analysed using the software supplied.
  • TuberLog is powered by a rechargeable battery which is charged by connecting to the USB interface of a computer or with the charging kit supplied.

Android App

The TuberLog connects to an Android tablet via Bluetooth. The app gives users the ability to see in real time the shocks received by the TuberLog. Operators can accurately identify the location and severity of the shock and quickly decide whether remedial work is needed.

Operators can select their own reporting thresholds, so small shocks show up as a green alert, intermediate ones as orange and severe ones as red. Each alert is accompanied by a different audible alarm.

The recorded data can be viewed in real time and can be viewed in different forms such as tables or graphs.

Interpretation of Results

Potato bruising level is related to impact, but variety, temperature and growing conditions all affect how much bruising occurs at a given impact.

TuberLog doesn’t measure bruise levels in real potatoes, but the user can interpret the impact information and change machine settings to reduce impact levels and minimise bruising.

Readings can be compared to Potato Hot Box bruise test results of potatoes taken from the same machine section. This provides the experience to interpret TuberLog results very quickly.

PC software allows detailed analysis of impact records

Why use TuberLog as part of quality control procedures?

TuberLog assists with the prevention of economic losses caused by bruising

TuberLog enables immediate improvements to quality problems in potato production

TuberLog can provide peace of mind that quality standards are being maintained

TuberLog should be used regularly so that bruising problems caused by poor machine maintenance or incorrect settings can be detected quickly. Machine settings are often changed, but the effects on bruising may not be realised. A quick check with TuberLog can make sure.
