## Abstract

A vacuum tumbling system for marinating meat including a vacuum sensor; an airtight driver; an outer vacuum chamber configured to monitor and pull a vacuum; and an inner vacuum tumbling chamber configured to enclose a marinade mixture, liquid, and the meat, configured to be disposed inside the outer vacuum chamber, and configured to pull the vacuum from the outer vacuum chamber through a small hole which is recessed on a bottom surface of the inner vacuum tumbling chamber. The outer vacuum chamber monitors the vacuum through the vacuum sensor, pulls the vacuum through the airtight driver, and tumbles the inner vacuum tumbling chamber in response to the airtight driver being driven.

## Claims

### Claim 1

A method for marinating a material in a vacuum tumbling system comprising an airtight driver, the method comprising:
monitoring a vacuum in an outer vacuum chamber;
tumbling an inner vacuum tumbling chamber, which is configured to enclose a marinade mixture, liquid, and the material and configured to be disposed inside the outer vacuum chamber, the outer vacuum chamber comprising an opening through which the airtight driver communicates with the inner vacuum tumbling chamber;
maintaining a predetermined vacuum level of the outer vacuum chamber based on a value of the monitored vacuum,
wherein the inner vacuum tumbling chamber is further configured to pull the vacuum from the outer vacuum chamber through a hole which is recessed on a bottom surface of the inner vacuum tumbling chamber; and
pulling the vacuum from the outer vacuum chamber through the hole of the inner vacuum tumbling chamber and through the opening of the outer vacuum chamber.

### Claim 2 (depends on 1)

The method of claim 1, wherein the inner vacuum tumbling chamber is tumbled by the airtight driver.

### Claim 3 (depends on 2)

The method of claim 2, wherein the airtight driver comprises:
a vacuum pump configured to be powered on or off based on the monitored vacuum;
a vacuum motor configured to drive the vacuum pump for pulling the vacuum;
a tumble motor configured to tumble the inner vacuum tumbling chamber; and
a circuit board configured to be connected to at least one of the vacuum pump, the vacuum motor, and the tumble motor.

### Claim 4 (depends on 2)

The method of claim 2, wherein the airtight driver is configured to be disposed inside the outer vacuum chamber.

### Claim 5 (depends on 2)

The method of claim 2, wherein the airtight driver is configured to be disposed external to the vacuum chamber.

### Claim 6 (depends on 2)

The method of claim 2, wherein the airtight driver is configured to be driven by an external electrical outlet.

### Claim 7 (depends on 2)

The method of claim 2, wherein the airtight driver is configured to be driven by a battery which is enclosed by the outer vacuum chamber.

### Claim 8 (depends on 3)

The method of claim 3, wherein the vacuum pump is configured to be powered on in response to the monitored vacuum being below the predetermined vacuum level.

### Claim 9 (depends on 3)

The method of claim 3, wherein the vacuum pump is configured to be powered off in response to the monitored vacuum being equal to or greater than the predetermined vacuum level.
