METHOD AND APPARATUS TO DETERMINE COLOUR OF EGG YOLK

摘要

The present concept is a method of preparing an egg to determine the color of the egg using an egg yolk cover. The egg yolk cover is dome-shaped with a base edge and inspection area. The egg yolk cover eliminates ambient light from impinging on the egg yolk and is used in combination with a light sensor to determine the color of egg yolks. The light sensor includes a single flat printed circuit board with a top and bottom side which includes at least one LED light and one color sensor, at least one light pipe receiving light from the LED and transmitting it onto a substrate at an angle theta and a tube frame including an optical tube for receiving light reflections from the substrate. The light pipes and the tube frame are compression fit between the printed circuit board and a lower housing. To determine the color of the egg yolk, the egg is first cracked onto a flat surface. The egg yolk cover is then placed over the egg yolk and the color sensor is placed onto the inspection area to measure the color.

主权项

1) An egg yolk cover for housing the liquid portion of an egg between the cover and a flat surface for the purpose of measuring egg yolk color, the egg yolk cover comprising:
a) an opaque cover adapted to cover the liquid portion of an egg, the cover includes a base edge which contacts with the flat surface and adapted to create a substantially light tight seal with the flat surface; b) wherein the cover includes a transparent inspection area adapted for viewing the egg yolk.
