Abstract: An apparatus for applying a liquid containing a post-harvest-treatment organic compound to generally spherical or ovoid produce items, the apparatus including: a first set of cylindrical brushes, each rotatable about its axis in a first direction, the axes of the first set of brushes being generally parallel, lying generally in a common horizontal plane, and positioned sufficiently close to one another to create a rolling transport platform having a series of alternating peaks and troughs for the items; a second set of at least one brush positioned above the first set so that the bristles of both sets are deformed as the items pass between them. The liquid is applied to the second brush set, which may include multiple rotating cylindrical brushes having horizontal parallel axes, at least one stationary or movable flat brush, multiple right-conical section brushes, or multiple cylindrical brushes having skewed, horizontal axes.

Abstract: The present invention provides both a process and apparatus for treating tubers in storage with chlorpropham (CIPC) dust or the dust of any other similar organic compound. The process includes the steps of forming minute particles of solid CIPC particles from a larger block or chunks of solid CIPC, and inducting the particles into an airstream which transports the particles to a tuber storage shed. For a preferred embodiment of the invention, the blocks or chunks of solid CIPC are fed into a hammer mill or like apparatus, which pulverizes the solid CIPC. Insufficiently fine particles are returned to the mill for further pulverization. Fine powder consisting of particles, each of which has a major dimension of less than about 5 micrometers, is transported by the ducted airstream from the separator to a storage shed containing a pile of tubers. The powder filters through the pile and coats exposed surfaces of the exposed tubers.

Abstract: The present invention is a sunlight reducing cover for intake and exhaust louvers on a food crop storage building. The invention also decreases the likelihood of ice formation or dirt fouling of the building louvers. The invention interfits within a frame, which is installed over the louvers, preferably inside the building. The invention is generally comprised of a free-flowing, air permeable, plurality of passageways. Each passageway having a first and a second end, with the passageways being of offset configuration wherein the first end is offset from the second end to an extent that a linear path does not exist between the two ends. The preferred embodiment of the present invention is generally comprised of a plurality of panels of generally wave form. The invention is manufactured by attaching the top surface of one panel to the bottom surface of another panel in such a fashion that the period of the wave form of each panel is 180.degree.
