Sorting & Grading

Sorting and grading is central to Compac's packhouse solution and incorporates our industry-leading Spectrim, Inspectra2 and InVision systems. These innovative systems allow packhouses to reduce the labor required for sorting, whilst significantly improving the consistency and accuracy of the sorted product.

With improved sorting capabilities, Compac customers are able to get more of their crop graded as premium, can reduce manual labor costs and increase throughout, resulting in greater financial returns, produce into higher value, premium grades and grow the financial return from their crop.



Spectrim is about combining the key elements within hardware, software and operational optimization to offer the most advanced sorting platform. Spectrim's capabilities are not only powerful, but easy for the operator to understand and use. For more information click here.

Sorting color grading

Compac sorting machines use a unique electronic weighing system that is unsurpassed in its accuracy. This precise weighing reduces the amount of produce give away in each pack and means higher crop returns for our customers. Our carriers feature four individual weigh points for improved accuracy and are specifically designed for high speed weighing of produce from 25 to 2000 grams.

Each carrier and load cell runner is measured for over 95% of the weigh cycle, providing maximum opportunity for precision weighing, even at high speeds of 10-15 pieces of produce per second, per lane.

Sorting color grading

Compac systems are accurate and easy to use. Intelligent learning software allows the systems to intuitively recognize produce types and adjust grading accordingly. Up to 30 images of individual produce are captured for improved accuracy with the system managing dark and light produce types automatically.

Compac is a pioneer in produce density sorting and is being used around the world to identify defects such as frost damage and loose or puffy skin. Our density sorting technology accurately separates frost damaged produce by using accurate diameter and weight readings for individual produce. The system calculates produce density from existing data using mathematical algorithms. The benchmark for acceptable produce can easily be adjusted by the operator. This technology is also being successfully used to remove puffy (loose skin) mandarins and internal breakdown in lemons.

Size and Shape

Sorting sizing

Our systems optically size produce by measuring multiple diameters and comparing these digital images to ensure the highest possible accuracy. Unusual shapes that impact diameter such as flatness and elongation, can be easily identified and separated. For citrus, diameter sizing is used to measure volume and density in order to separate loose skin or "puffy" fruit. For apples, stonefruit, cherries and onions, it is possible to detect and plot the equatorial and shoulder diameters using the stem detection feature. The end result is produce that fits correctly into packaging with maximum consumer appeal.

Surface Defects

Sorting surface defects

Our systems use high-end cameras and advanced software to sort based on the presence of defects on the produces surface. The quality and consistency of defect sorting sets Compac apart from other packhouse solutions.  Our systems detect and grade on minor to major defects ranging from skin blemishes, insect damage and misshapen fruit. The systems also detects physical damage, identifying problems that are often difficult pick up with the naked eye but will cause fruit to breakdown in market. Systems accurately separate damaged fruit prior to shipping to ensure you get the best return from your crop.

Internal properties


Inspectra's NIR sensors sort produce on a variety of internal properties such as brix level, internal defects and internal color. The built in spectrometer accurately measures the reflected and transmitted light. This safe, non-invasive sorting technology helps reduce financial losses in bad crops. Compac was the first company in the world to use NIR for the agriculture industry and this has given us the edge over other NIR manufacturers and we continue to lead the way in our research and development of this technology.
