The present invention relates to a food processing device, for example but not exclusively, a gripper, a conveying hook, or a collection cup (1), having at least one processing surface portion of matt stainless steel having the following roughness characteristics: a roughness value Ra, 0.2Ra1.2 (m), and a peak density value Rpc, 40<Rpc<140 (1/cm). It has been found that with devices treated in this manner, the application of vision technology is appreciably improved, so that much more reliable images are obtained. An example of this concerns observing yolk in albumen upon the breaking of eggs in egg breakers. Further, a particularly advantageous combination of usefulness is obtained, in this case for vision and cleanability.

An egg-breaking system is provided that includes a plurality of nodes arranged in which one or more cracker assemblies are disposed. The nodes are arranged in a matrix of rows and columns within the egg-breaking system. The egg-breaking system can be used in an egg processing line in which eggs are subjected to a variety of processing steps.

An egg breaking apparatus for breaking eggs having shell and contents including yolk and albumen, includes a plurality of egg breaking devices, each adapted for holding, breaking and opening a single egg at a time, and an albumen collection unit for collecting albumen remaining on shells and/or egg breaking devices after the contents have been discharged under the influence of gravity. The albumen collection unit has at least one collection member with at least one opening adapted for allowing the passage of a fluid and at least one cover member adapted for covering the opening(s) in the collection member(s). The collection member(s) and/or the cover member(s) are moveable between a first mutual position where the cover member(s) cover(s) the opening(s) and a second mutual position where the opening(s) is/are uncovered.

The present invention relates to a method for the detection of egg yolk in albumen, for example, but not exclusively, at least one yolk spot, comprising, breaking an egg, separating albumen and yolk, collecting albumen and yolk separately in a yolk cup and in an albumen cup, imaging of the albumen cup substantially from above with a camera, whereby an albumen image is obtained, and imaging, substantially from above, of the yolk cup, having yolk area Ay, a preselected subarea Py, whereby a yolk image in a preselected color system Sy is obtained.

An eggshell extraction implement comprising two hingedly-connected working arms and a basket, wherein the basket is used to scoop eggshells (shell fragments) from egg material in a pan.

Provided are kitchen devices for cooking eggs using various cooking methods. For example, kitchen devices provided herein comprise a storage component configured to store a plurality of raw eggs, a cracking component configured receive a raw egg of the plurality of raw eggs from the storage component and crack the raw egg, forming a cracked egg, a cooking component configured to receive the cracked egg from the cracking component and cook the cracked egg, forming a cooked egg, and a warming component configured to receive the cooked egg from the cooking component and warm the cooked egg.
