Impact Recording Device (IRD)


We understand the needs of the agricultural community because we are a part of it!

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 sources of damage allowing you to make adjustments to handling systems and protect 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.


The Science

  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.

  To better understand this process, imagine an apple being dropped from 12 inches onto a rubber surface.  Now imagine the same apple being dropped onto concrete.  It is possible in this scenario that the impact G force is the same for both drops BUT the damage caused is significantly different because of surface characteristics.  The rubber surface will be able to absorb the G force over a greater amount of time thereby changing the velocity and causing less damage to the apple.  The concrete will have a short time period of velocity change and the energy of the G forces will cause damage to the apple in the form of bruise as the energy is absorbed by the fruit.  What does this mean for you?  It means that the IRD can identify where bruising potential exists and allow you to make a change.  Sometimes the change is as simple as reducing a drop or adding a padding material to a corner.  Other damage points may be less identifiable and need more significant alterations to avoid product damage.

  The spherical shape of the IRD creates a consistent evaluation of the handling system.  All points on a sphere are equidistant from the center.  This shape provides a consistent interaction with the systems it travels through.  No fruit or vegetable is of exactly the same dimensions, neither are the handling systems they move through making it important to use a measuring device of a consistent shape and weight to provide reliable data that can be compared to other data generated in the same manner.

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 I.R.D has been a global standard for bruise evaluation of fruit, vegetable and food product handling systems for over 20 years.  Tested and supported by researchers and growers worldwide, the IRD is responsible for reducing waste and adding to the bottom line of countless operations.
