Breaking strength
The stability of the egg shell is one of the most important quality parameters in a hen’s egg.
With our FEST device, we offer you a quick and easy solution for determining the breaking strength.
The pure measuring time is 2 seconds for a single egg. Add to that the time required to insert and remove the egg, and you can comfortably test up to 900 eggs per hour.
Haugh-Units
To determine the Haugh units, the egg is cracked on a flat glass plate after weighing.
The egg white height gauge is then used to determine the egg white height at a distance of approx. 1 cm from the edge of the yolk.
The formula for calculating the Haugh unit is:
Wobei:
- HU = Haugh unit
- h = specified height of the albumens in millimeters
- w = mass of the eggin grams
The calculation is done automatically in our software.
Alternatively, you can read out the data from a table.
Yolk color
The color of the egg yolk is traditionally expressed in “Roche values” from 1 to 15.
The name “Roche” refers to the company Roche, which released the color fan shown below a few years ago. Roche was acquired by DSM Nutrition Products GmbH a few years ago.
Our measuring instruments work with an R-G-B sensor whose filter curves correspond to the human eye (3-range method). From the red, green and blue components we calculate the Lab* values from which we then determine the Roche value. In our software, both the Lab* values and the Roche values are stored.
Shell thickness
For the determination of the shell thickness we offer a special micrometer screw, where one measuring surface is rounded. This makes it possible to correctly determine the thickness of the concave (curved) eggshell. The device can be connected to a PC via our data collector.
Microprocessor technology
We develop and produce customer specific electronic circuits and controllers. Usually these are based on AVR, Cortex-M3 and/or ESP8266 (IOT) processors.
Fields of application are:
- Key depots
- Alarm systems
- Image processing systems
- Production data acquisition
- Machines for plastics processing
- Input/output modules for PCs
- Analog data acquisition
Software for microcontroller
Our customer-specific controllers usually include system software (firmware). We develop this mainly in C++.
Software for PC-Systems
- MySQL
- MS-SQL
- Delphi
- PHP
- Python
Software for Android – Systems (Apps)
We develop data acquisition systems based on Android devices. Shown here are special Android devices with integrated RFID reader and barcode scanner. However, commercially available smartphones and Android tablets are also used.
The terminals can be connected, for example, with our breaking strength meter or with electronic carts via Bluetooth.
The data is first stored locally on the device and later, i.e. when an Internet connection is available, transferred to a database server via Wlan. The data can then be processed and evaluated centrally.
These systems are in use worldwide with several hundred terminals.
- Java
- PHP
- JSON
- SQLite
- HTML
