Ten years of Smart Grader practical experience: ‘grading much more seed’ CU LTIVATION AND TECHNOLOGY ‘In some seed potato lots, the scab percentage is so high that it’s impossible to inspect them by hand. Then you can still sift 20 to 30 percent of export-worthy tubers from one of your colleague’s lots,’ says Angelo Uitdewilligen. For 100 hectares of grading work The fact that not all years are the same and have their own problems can also benefit the seed potato grower, namely contract work. ‘This year scabies is a problem. In some seed potato lots, the in all, the seed potato grower now has grading work for 100 hectares of seed potatoes from his own crop and also some tons of contract work. This means that the Smart Grader may even run 24/7 for some periods. And up to 60 tons ‘This means that the Smart Grader may even run 24/7 for some periods’ percentage is so high that it’s impossible to inspect them by hand. But the Smart Grader can do it. Then you can still sift 20 to 30 percent of export-worthy tubers out of one of your colleague’s lots. For example, Uitdewilligen also used the Smart Grader to grade a lot of Bintjes with a very high percentage of bottlenecks, a form of abnormal tubers. ‘You just couldn’t inspect them by hand.’ All of seed potatoes a day may pass under the cameras. Uitdewilligen proudly shows his smartphone, on which he can follow and, if necessary, adjust the operations of the grading machine. ‘I can now grade all the seed potatoes on my own and I don’t have to be there all the time. Occasionally, I adjust a few settings and see that there’s enough material for the Smart Grader to run for a few more hours.’ And if he can’t figure out a setting or a malfunction, he’ll be in touch with Jos Broeders in no time. ‘I can always contact him and he can also see spot malfunctions by remote control, and analyse and adjust machine settings if necessary. In that respect, I am very happy that Jos and his mate will continue with their service and sales, because we are very pleased with the Smart Grader and we hope to stay that way for many years to come. ● Leo Hanse Potato World 2019 • number 3 21 Pagina 20
