How do you Vacuum Seal Liquids ？

Vacuum sealing liquids—whether it’s homemade soup, marinated meats, or fresh smoothies—feels tricky at first: too much suction, and you risk spilling liquid into your handheld cordless vacuum sealer; too little, and your seal won’t keep contents fresh. But with the right steps, it’s easy to lock in flavor, prevent freezer burn, and protect your handheld cordless vacuum sealer—no messy mishaps required. Below’s how to do it safely and effectively.

Step 1: Prepare the Handheld Cordless Vacuum Sealer

If the silicone rubber sheet with spring was removed, reinstall it first. This component is essential for preventing liquid from leaking into the machine’s internal parts during wet vacuuming.

Step 2: Set Up the Draining System

Insert the draining tube into the best cordless portable vacuum sealer’s exit hole. This tube acts as a channel to direct excess liquid away, stopping it from spraying out of the machine and keeping the area clean.

Step 3: Position the Bag and Tube

 
Move the liquid-filled vacuum pack bags near a washing sink. Place the free end of the draining tube into the sink (or a designated collection box) to catch any liquid that drains out during the process.

Step 4: Secure the Vacuum Bag to the best cordless portable vacuum sealer

Align the open edge of the liquid-filled bag with the machine’s vacuum seal strip. Press the vacuum sealing machine firmly onto the vacuum pack bags to create a tight seal—this ensures air (and liquid) is suctioned through the correct path, not escaping from gaps.

Step 5: Start the Vacuum Process

Follow the machine’s general instructions to start the vacuum cycle.

The vacuum machine will automatically stop vacuuming when its water tank is full. To continue, press the power button again—this restarts the vacuum and drains the collected liquid. Repeat until the bag reaches a fully vacuum-sealed state.

Critical Notes

1. Mandatory Component Check: The silicone rubber sheet with spring must be installed before wet vacuuming. Without it, liquid can enter the machine and cause malfunctions.
2. No Direct Fluid Vacuuming: Never place the machine itself into liquid, or vacuum pure liquid directly (without a bag). This will damage internal parts and lead to equipment failure.
3. Clean the Machine Post-Use: After sealing marinated food or liquid-containing items, fill a vacuum seal bag with clean water. Run a short vacuum cycle to suck the water through the machine—this flushes out residual liquid that could cause odors. Stop once all residual fluid is drained.
4. Wipe the Vacuum Sealed Bags: After vacuuming, small amounts of liquid may drip onto the valve bag. Use a clean cloth or paper towel to wipe the bag dry before storage.
