Abstract
Shellfish are placed into a chamber which is brought rapidly to a high pressure. A lid of the chamber is magnetically sealed. The magnets are quickly released to allow the chamber pressure to blow off the cover with large springs absorbing energy. The immediate decompression tends to open the shells. A sonic or ultrasonic source within the chamber augments the process.
