Excerpt from Bin Fronts for Potato Storages The use. Of bin fronts is justified because they provide better space utilization in the potato bin, but the other functions they perform, such as creating a level pile for better ventilation, separating bins from alleyways, and providing pressure relief at doors, are important also. The design of bin fronts, the removable ao cess panels to potato-storage bins, is discussed in this report and two experimental types of bin fronts suitable for spanning openings up to 24 feet Wide are detailed. The experimental fronts consisted of a glued-tee panel and a slot ted panel. Both designs were examined and tested for use on long-span applications. Both were effective in terms of the design criteria: (a) adequate strength, (b) reasonable weight. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from Pressures on Walls of Potato Storage Bins In order to design and construct economical potato storage structures it is necessary to know what pressures potatoes exert on walls and partitions of storages. A series of studies was conducted in Maine, Colorado, and Minnesota to determine these pressures. Maine and Colorado studies were based on the deflection of calibrated wood planks in bin walls. Pressure cells made of two steel discs were also tried at Colorado. In the Minnesota tests, pressures were measured by the deflection of calibrated steel bars supporting vertical wall panels. Early analyses showed that potato pressures on bin walls followed the same pattern as ear corn but were lower. Potato pressures were found to in crease with time both in tests and in practice. More partitions fail as an adjoining bin is emptied than when a bin is filled next to one that is empty. Settling of potatoes may leave voids, into which potatoes later may wedge, due to vibration. Vibration caused by passing trains and trucks is more noticeable after the ground freezes. But vibration due to an avalanche of potatoes in an adjoining bin, together with sudden release of supporting pressure, often causes failure in a partition designed for a static load. Within the limits of deflections observed, there is little difference in the unit pressure on the front and sides of a bin, which is longer than it is wide.

Excerpt from An Improved Elevator for Deep Bin Potato Storages Since the prototype was built, a number of changes have been incorporated, and it is anticipated that further improvements will be made. A number of these elevators have been constructed and installed in commercial storage and packing plants in the Red River Valley area. Each of these installations re quired modification to fit existing facilities. Some of these modifications are discussed in this report. These elevators were adopted commercially during the 1954-55 and 1955 56 packing seasons and have satisfactorily performed the operation for which they were designed.
