egg breaker Interview Questions and Answers

1. What is an egg breaker?

   • Answer: An egg breaker is a device or method used to efficiently and safely break eggshells and separate the egg white from the yolk, often used in commercial food processing or large-scale baking operations.

2. Describe the different types of egg breakers.

   • Answer: Egg breakers range from simple hand-held cracking devices to automated, high-capacity industrial machines. These can be categorized by their operation (manual vs. automatic) and their functionality (cracking only vs. separating yolk and white).

3. What are the advantages of using an egg breaker over manually breaking eggs?

   • Answer: Automated egg breakers offer significantly increased speed and efficiency, reduced labor costs, improved hygiene (less shell contamination), and consistent egg processing.

4. How does a manual egg breaker work?
