Egg Pasteurization Spraying Chamber and Meandering Conveyor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing egg pasteurization methods require high energy input for heating and circulating water baths, and they can cause the yolk to move upwards during pasteurization, affecting the appearance of cooked eggs.
Innovation Solution
A device and method for pasteurizing eggs using a chamber with a spraying device that applies heated or warmed liquid to the eggs, allowing for efficient pasteurization without the need for a water bath, and incorporating a meandering conveyor system to rotate the eggs and keep the yolk centered.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If eggs are passed through a water bath in carriers, then pasteurization is achieved, but energy consumption is high and temperature control is complex
Solution Approach 1:
The patent extracts the eggs from the water bath system and places them in a dry heating chamber. The heating chamber directly heats the eggs without requiring a large volume of water to be heated and circulated, thereby significantly reducing energy consumption while maintaining pasteurization effectiveness.
Solution Approach 2:
The patent introduces a heating chamber as an intermediary device between the egg loading and pasteurization completion. This chamber provides controlled thermal exposure to the eggs through direct heating elements, enabling precise temperature control and efficient energy transfer without the complexity of water bath circulation systems.
2Reliability
If eggs are rigidly arranged in carriers, then pasteurization is achieved, but the yolk moves upwards affecting appearance
Solution Approach 1:
The patent transforms the static carrier arrangement into a dynamic system by rotating the carriers during the pasteurization process. This rotation prevents the yolk from settling in one direction (upwards) and maintains it centered in the egg, preserving appearance while ensuring uniform heat distribution for effective pasteurization.
3Reliability
If a water bath system is used, then pasteurization is achieved, but temperature control is complex
Solution Approach 1:
The patent removes the complex water bath temperature control system and replaces it with a simplified dry heating chamber. The heating chamber uses direct heating elements with simpler temperature sensors and control mechanisms, reducing system complexity while maintaining reliable pasteurization through controlled thermal exposure.

AI summary
An apparatus for pasteurizing eggs includes a feeder for receiving and transferring eggs to a carrier, a chamber for heating and pasteurizing the eggs, a conveyor for moving the carrier with the eggs through the chamber, a transfer station for transferring the eggs from the carrier to a transport device, and a packing station for packing the coated eggs. A spraying device sprays liquid on the eggs in the chamber can be sprayed with a liquid to pasteurize the eggs.
