Bogside cleaner testing

Harvest is starting soon, and as we discussed last week, we took delivery on a second bogside cleaner for use in the upcoming season!

Last year, we began using this new equipment to help improve efficiency. During the harvest, berries are placed on a truck via an elevator. The truck then goes to our packing house to unload and prep the berries for the receiving station by removing as much bog debris as possible. The bogside cleaner improves this process by removing the packing house step entirely and removing debris as the berries come out of the bog. This is better on fuel and easier on the team, as it requires fewer people in the water. As with any new equipment, there was a learning curve, but our team made modifications as they became necessary and took notes for subsequent harvests.

“It’s been a long process,” says COO Bryan vonHahmann. “When we first started considering a berry pump, we went out to Wisconsin and looked at three or four makes of cleaners as well as looking at one owned by [our neighboring growers] the Lees. We ended up going with Paul’s Machine & Tool because they’d already done quite a bit to accommodate the user interface to make it more intuitive, and they were also very willing to customize it however we wanted. In practice, this meant changing the 6 inch pump to an 8 inch one, as well as asking them to build it a little higher to make it easier for our trailers; a few small changes, and some significant ones. But they provided us with great service, and came out themselves to help set everything up last year.”

The real test was during harvest itself, of course, and as expected, the team found that the machine would need some modifications based on practical use. (As Bryan says, succinctly: “When we placed the order, we didn’t know what we didn’t know.”) One of the issues the team discovered was finding a lot of bog debris in the final product, as well as a diminished ability to remove the wastewater fast enough. “We wanted it to be as efficient as possible,” Bryan says, “so we made some minor changes during harvest last year to remove vines and trash. But it became more labor intensive than it was worth.” So for the second machine, we asked Paul’s to make some design changes. The new berry pump added extra row of cleaning grates to the cleaning box and changed spacing on the box. At same time we sent the old cleaning box back and they sent us the new 5 grate design in return. The combo of the new spray boom and an additional cleaning grate should provide better quality fruit for the trailer to take directly to the Chatsworth receiving station.

Testing the new machine on a young bog will be useful for a couple of reasons. Young beds have yet to develop a dense canopy, and while they often yield fruit, a high percentage of that fruit contains rot. This makes them a good place to test run new equipment immediately pre-harvest. “We may well need design changes,” says Bryan, “but we’re looking forward to trying it and see how the new design works. The more fruit that goes in, the less water goes in. We’re going to run the older one on two bogs and bring the new one out for a third bog. We’re trying a modified 5 grate cleaning box with wider spacing on the teeth on one bog, and the standard 5 grate on the other to see if it makes any difference. In young beds you’re going to get a lot of rot and vines; it’s just the nature of the beast. But we’re hoping the wider tines will help push those through.”
