Impact Recording Device (IRD)


Potato Handling System

Apple Handling System

The IMPACT RECORDING DEVICE (IRD) is an advanced technology tool for monitoring potentially damaging impacts to your fruits, vegetables and food products.  From the field to the processed package and all points in between, the IRD will identify potential sources of damage allowing you to make adjustments to handling systems and maintain quality.

Using internationally patented technology the IRD identifies the location and severity of impacts delivered to produce during handling procedures.  The IRD is transferred through machinery and other handling systems with the normal course of fruit and produce, this allows the IRD to experience the same "bumps and bruises" that your commodity is experiencing.  Impact data is recorded and stored on board the IRD, later this data is uploaded to your tablet or PC for analysis. PCIRD, our IRD software package, will generate reports from the data collected and allow for straight forward interpretation of where the most significant impacts occur.  Severity of impacts is calculated in both maximum acceleration (G) and velocity (m/s) for each impact.  This is the key to understanding where the damaging impacts occur; not all impacts create damage, to separate the non-damaging impacts from the damaging impacts you must know BOTH the acceleration and the velocity - Techmark's IRD is the only product on the market that measures both of these critical data points.

Benefits of using the IRD include:

-Reduce bruise and shatter damage to fruits, vegetables and other food products.

-Maximize incentives, bonuses and other merit compensation.

-Improve produce appearance and customer/buyer acceptance.

-Reduce post harvest respiration and disease loss.

-Improve storage and shelf life of fruits and vegetables.

-Accurately and reliably calibrate handling equipment performance across locations, suppliers or seasons.

-Calibrate handling equipment prior to harvest or packaging to avoid unnecessary bruising.

Techmark's IRD is a global standard for bruise evaluation of fruit, vegetable and food product handling systems.  Tested and supported by researchers and growers worldwide.
