## Abstract

The invention is a depositing device (5) for depositing flowable food containing gas comprising a pressurized feed line conveying flowable food containing gas under pressure into the food; piston (60) means operatively connected to the feed line comprising a piston and a chamber (61); an outlet to deliver food at the atmospheric pressure into molds (85). The device comprises a pressure retaining means (9) arranged to retain the product in the chamber at the same pressure as the line pressure and to deliver the product through the outlet as pressure in the chamber increases from the line pressure upon descent of the piston in the chamber.

## Claims

### Claim 1

A depositing device for depositing flowable food containing gas, the depositing device comprising:
a pressurized feed line conveying flowable food containing gas under pressure into a food;
piston means operatively connected to the feed line comprising a piston and a product receiving chamber, the piston moveably arranged in the product receiving chamber and positioned opposite to an apertured plate that forms an end of the product receiving chamber;
a delivery chamber on an opposite side of the apertured plate relative to the product receiving chamber;
an outlet positioned at an end of the delivery chamber to deliver food at atmospheric pressure into molds; and
a pressure retaining means positioned at the outlet for retaining the food in the product receiving chamber at the same pressure as a line pressure and delivering the food through the outlet as pressure in the product receiving chamber becomes greater than the line pressure upon descent of the piston in the product receiving chamber, whereby there is no decrease in food pressure until food exits the outlet, wherein the pressure retaining means comprises a stem extending from the product receiving chamber through the apertured plate into the delivery chamber, the stem comprises a sealing portion that contacts an abutting portion of the delivery chamber to close the delivery chamber, the end of the delivery chamber at which the outlet is positioned is opposite to the abutting portion of the delivery chamber, and the sealing portion of the stem moves toward the outlet and out of contact with the abutting portion of the delivery chamber to open the delivery chamber.
