A modular star system for grading, cleaning, and transporting produce includes opposing, first and second hub modules with opposing, tapered surfaces, and plural finger modules separated by the first and second hub modules. Each finger module has finger members that are color-coded and the finger module and first and second hub modules are disposed on a rotatable shaft. Outer surfaces of either of the finger or hub modules are color-coded, and are substantially perpendicular to the long axis of the shaft. There is also a method of using the modular star system for grading, cleaning, and transporting produce.

A modular nut cleaning plant comprises a nut sizer and a stick remover mounted to the nut sizer. A vacuum unit is mounted to the stick remover. A nut product stream will pass on the stick remover through the vacuum unit which will vacuum light debris from the nut product stream. The nut product stream moves on a chain on the stick remover. Large debris and sticks that do not fall through openings in the chain will pass into a debris conveyor. Nuts and debris that fall through the openings in the chain will be delivered to the nut sizer. The nut sizer will rotate and tumble nuts and debris in the nut product stream. Nuts of an undesirable size and debris will pass into a debris conveyor. Nuts of a desired size will pass through the nut sizer into a chute or other conveyance to be delivered to further nut processing apparatus.

An apparatus includes a first production line configured to generate aqueous ozone with a first ozone concentration. The apparatus also includes an additional production line configured to generate aqueous ozone with an additional ozone concentration. The first production line and the additional production line include a flow switch, where fluid is configured to flow through the flow switch. The first production line and the additional production line include an ozone generator, where the ozone generator is configured to generate ozone when the fluid flows through the flow switch. The first production line and the additional production line include a fitting coupled to the flow switch and the ozone generator, where the fitting is configured to combine the generated ozone and the fluid to generate the aqueous ozone. The first production line is configured to generate aqueous ozone independently from the additional production line.

A device for cleaning root vegetables include at least two rollers each rotatably mounted about an axis perpendicular to a direction of travel of the root vegetables on the rollers. At least one of the rollers is equipped with a means for heating its outer wall. Thus, with the outer wall of the roller being heated, this has the effect of drying soil that is possibly stuck thereon. This drying is enough to make the soil crisp and to overcome the suction phenomenon of wet soil on the roller and on reliefs of the roller. Vibrations due to the displacement of the root vegetables on the rollers ensure that the dried soil is detached and falls to the ground.

A treatment system, including a conveyor bed configured to transport a plurality of products; a brushing device located along the conveyor bed and having one or more brushes that include a first antimicrobial compound; a surface treatment device including a lamp configured to emit light of a peak wavelength directed toward a portion of the conveyor bed; and a coating device configured to deliver a coating mixture onto the plurality of products on the conveyor bed.

A pre-cleaning system is provided. The pre-cleaning system is for providing purification of unshelled hazelnut at least partially from foreign substances before processing of unshelled hazelnut. The improvement of the pre-cleaning system is that the pre-cleaning system includes at least one first separation unit where the foreign substances, which are outside the acceptable dimensions of unshelled hazelnut, are sieved and separated, at least one second separation unit positioned in the vicinity of said first separation unit and which can provide separation of foreign substances, which have specific weight lower than the specific weight of acceptable unshelled hazelnut, by means of an artificial air flow provided in at least one flow path provided thereon, at least one third separation unit positioned in the vicinity of said second separation unit and which can provide separation of foreign substances, which have specific weight higher than the specific weight of unshelled hazelnut.

Described herein are conveyor systems and application units which can be used to transport and simultaneously treat, or to facilitate treatment and inspection of produce, agricultural products, or other items. The conveyor systems and application units can be configured to allow products to be simultaneously rotated as they are moved along a packing line, which can facilitate the uniform application of spray coatings and/or allow the products to be uniformly blow dried while they are moved. Exemplary conveyor systems and application units can include a bed formed of a plurality of rollers and a rotation inducing device that causes the rollers to rotate while they are laterally transported, thereby causing the products lying on top of the bed to rotate during transport.

A nut sizer includes a nut sizer frame and a rotatable nut sizer cage mounted therein. A motor is attached to the nut sizer frame at an intake end thereof. The motor will drive a drive sprocket which will in turn drive a reel sprocket that is connected to the rotatable sizer cage. A chain engages the drive sprocket and the reel sprocket. The sizer cage may be lifted from the nut sizer frame by removing the chain. The nut sizer cage is a sectioned sizer cage and includes a first sizer section and a second sizer section detachably connected thereto.
