Disclosed herein are systems and methods for processing waste egg shells into (i) a first product including calcified egg shell particles having diameters of 3μ or less, and (ii) a second product including calcified egg shell particles having diameters in a range from about 3μ to about 7μ. The first product may be used as a CaCO.sub.3 substitute for paint compositions and plastics compositions. The second product may be used as a CaCO.sub.3 blasting media substitute for use with abrasive blasting equipment.

A method and a device for treating poultry eggs with an electron beam bundle to sterilize the calcareous shell are disclosed. The method includes moving at least one egg through the beam path of an electron beam source; irradiating the eggs, whereby the calcareous shell is irradiated with a varying dose; and either carrying out an irradiation encompassing all regions of the calcareous shell of the egg by employing the electron beam bundle, whereby an element is inserted into the path of the electron beam bundle; carrying out an irradiation of a rolling/rolled egg by employing the electron beam source in the path of the electron beam bundle; or carrying out an irradiation of the held eggs by employing the electron beam source in the electron beam bundle path at a zero degree position of one side in a device arranged upstream of a turning device.

An egg grasp device is provided. Such a device includes a body and a plurality of elongated members extending from the body. The elongated members are interlaced to form a sheath capable of retaining an egg. The sheath has a distal end and a proximal end at which the elongated members are operably engaged with the body. The elongated members cooperate to define an opening at the distal end through which an egg is received when the elongated members engage and deflect about an egg such that the egg is seated within the sheath. Associated systems and methods are also provided.

A vertical washer or dryer, such as integrated into an egg handling operation. The vertical washer or dryer includes a vertically extending body supporting a carousel conveyor adapted to support pluralities of eggs during transport in successive ascending and descending fashion within the body between an inlet location and an outlet location of the body. A first egg conveyor communicates the eggs with the inlet location of the carousel conveyor, a second egg conveyor communicating the eggs with the outlet location. A least one of a plurality of egg washer spray bars or, in the separate variant, a plurality of egg dryer air knives, are integrated into the body in communication with the carousel conveyor for washing/drying the eggs while supported upon the carousel conveyor.

A method of treating a biological surface. The method includes a first generator dispersing a first dry fog within a sealed chamber, then exhausting the first dry fog from the sealed chamber. Further the first generator or a second generator dispersing a second dry fog within the sealed chamber, then exhausting the second dry fog from the sealed chamber.

A system for filtering and recirculating a wash fluid associated with a piece of equipment. An outlet line extends from a drain location of the piece of equipment for communicating the wash fluid from the equipment to a first stage particulate removal filter. A further conduit extends from an outlet of the first stage filter for communicating the wash fluid to a first tank. A second stage filter is in communication with a first outlet extending from the first tank for continuously redirecting a subset portion of the fluid through the second stage filter. A return conduit extends from an outlet side of the second stage filter which is communicated with a second outlet extending from the first tank at a rejoining location for redirecting a recombined fluid back to an intake line for redelivery to the piece of equipment.
