Abstract
A meat pickling method whereby meat pieces are placed in a container with brine, the container is pressurized with nitrogen gas and rotated. Subsequently, a vacuum is applied to the interior of the container and then the container is swept with nitrogen gas. Atmospheric pressure is then established in the container, the rotation stopped and the meat removed.
Claims5
A pickling method comprising the steps of:
- a. placing in a container pieces of meat to be pickled, said container being mounted for turning about a horizontal axle whereby said meat tumbles into and out of any fluid which may be in the bottom of said container;
- b. adding to the said container a quantity of liquid brine which corresponds to the mass of the pieces of meat to be pickled, whereby said meat and brine rest on the bottom of said container when said container is stationary and tumble while said container rotates about said horizontal axle;
- c. pressurizing the container with an inert nitrogen gas to a pressure greater than atmospheric pressure and less than 3 bars, whereby space within said container which is not filled with said brine is a pressurized atmosphere of nitrogen;
- d. rotating the container;
- e. applying a vacuum to the interior thereof;
- f. sweeping the container with an inert nitrogen gas;
- and then
- g. reestablishing atmospheric pressure in the container after a predetermined time and stopping said rotation before opening the container.

A pickling method comprising the steps of:
- a. placing in a container pieces of meat to be pickled, said container being mounted for turning about a horizontal axle whereby said meat tumbles into and out of any fluid which may be in said container;
- b. adding dry salt to the interior of the container in a quantity which corresponds exactly to the mass of pieces of meat to be pickled before putting the container in rotation;
- c. pressurizing the container with an inert nitrogen gas to a pressure greater than atmospheric pressure and less than 3 bars, whereby space within said container remaining above said brine is a pressurized atmosphere of nitrogen;
- d. rotating the container;
- e. applying a vacuum to the interior thereof;
- f. sweeping the interior of the container with an inert nitrogen gas;
- and then
- g. reestablishing atmospheric pressure in the container after a predetermined time and stopping said rotation before opening the container.
