Using Greefa’s iFA GeoSort grader, Stemilt can get an accurate reading on the internal characteristics and Brix value of each apple. Apples that don’t meet standards are rerouted to a downgrade sizer and additional sorting, while apples that continue down the line are packed into trays or bags. The images are analyzed by computer software and the apple is accurately sorted according to its size, color, and internal and external quality or defects. Apples move along the Greefa sizer through the “brains” of the line, where HD cameras rapidly take up to 60 images of each piece of fruit while it rotates. The new apple line uses similar technology as the electronic cherry packing lines in which Stemilt has recently invested heavily. Want To Lessen Pests in Your Farm Fields? Intercropping Might Be the Answer We have the flexibility to pack multiple sizes and grades and also reduce the number of touches to the fruit, which is important in maintaining a high quality pack.” “The benefit of having one of the longest apple sizers in the world is having so many drop points for the fruit. “It just keeps going and going,” said Fulbright. Starting with a blank slate allowed for the installation of the long Greefa sizer – which is nearly the length of a football field. Stemilt’s operations team led the construction of the new line, which began by completely deconstructing the existing commit-to-pack line. The technology is able to efficiently and gently size and sort apples and will help us deliver great consistency in every box.” “The line relies on electronic, or optic, sizing and defect sorting technology to reduce manual sorting of fruit and human error. “We’re excited about the addition of our new Greefa commit-to-pack line at Olds Station,” said Jay Fulbright, VP of operations and special projects at Stemilt. It features the latest generation of external defect sorting (iQs IV) and internal quality sorting (iFA GeoSort) from Greefa and a long, gentle sizer with 79 drop points to pack apples gently and with great consistency The Wenatchee, WA, company recently unveiled a new, high-tech apple line at its Olds Station facility.
