The Xiaomi automatic vacuum sealing machine is a compact countertop appliance that removes air from special bags or rolls to keep food fresh up to five times longer than regular storage. It works by suctioning out oxygen, which slows the growth of mold, yeast, and bacteria, and it also prevents freezer burn on meats and leftovers. This guide walks you through your first seal, from choosing the right bag to cleaning the machine, so you get a tight, leak-proof seal every time.
Ingredients
- Xiaomi vacuum sealing machine (model with built-in cutter and roll storage)
- Xiaomi vacuum seal bags or vacuum seal roll (5 ft / 1.5 m roll makes about 10 small bags)
- Food to seal: e.g., 1 lb (450 g) raw chicken breasts, 2 cups (300 g) berries, 1 cup (150 g) coffee beans
- Paper towel (for drying food surfaces)
- Optional: freezer-safe marker and label
Instructions
- Plug in the machine and place it on a flat, dry surface. Open the lid by pressing the two side release buttons; the sealing strip and vacuum channel should be clean and dry.
- If using a roll, cut a piece about 3 inches (7.5 cm) longer than the food you plan to seal. For example, for a 6-inch (15 cm) chicken breast, cut a 9-inch (23 cm) piece. If using pre-made bags, skip to step 4.
- Seal one end of the cut roll: place the open end flat across the sealing strip, close the lid, and press the “Seal” button (the one with a single line icon). Wait for the beep and the indicator light to turn off, about 3–5 seconds. This creates the bottom of your bag.
- Place the food inside the bag, leaving at least 2 inches (5 cm) of empty space at the open end. For moist foods like raw meat or berries, pat the surface dry with a paper towel first—excess moisture can prevent a good seal.
- Lay the open end of the bag flat across the sealing strip, making sure it is straight and not wrinkled. Close the lid firmly until both sides click.
- Press the “Vacuum & Seal” button (the one with a vacuum icon). The machine will automatically suck out air and then seal the bag. This takes about 20–30 seconds for a standard bag. Wait for the beep and the indicator light to turn off before opening the lid.
- Open the lid and remove the sealed bag. Check the seal: it should be a smooth, continuous line with no gaps or wrinkles. If the seal looks weak, cut off the sealed edge and repeat steps 5–6 with a fresh end.
- For delicate items like bread, cookies, or soft cheese, use the “Vacuum” button only (not “Vacuum & Seal”) and stop the machine manually when the bag is about 80% compressed, then press “Seal” to close it. This prevents crushing.
- Label the bag with the contents and date using a marker. Refrigerate or freeze according to the food type.
- Clean the machine after each use: wipe the sealing strip and vacuum channel with a damp cloth. Do not submerge the machine in water.
Tips
- Dry food edges: Any liquid near the seal line can cause a weak or failed seal. Always pat meats, fruits, and vegetables dry before bagging.
- Double seal for freezer: For long-term freezer storage (over 2 months), run the “Seal” function a second time just below the first seal to create a backup barrier against freezer burn.
- Pre-freeze liquids: Soups, stews, and marinades should be frozen in a tray or muffin tin for 2–3 hours until solid, then vacuum sealed. This prevents liquid from being sucked into the machine.
- Leave headroom: Always leave at least 2 inches (5 cm) of bag material above the food. The vacuum process needs space to pull air out; too little space causes a poor seal.
Serving Suggestions
Vacuum-sealed foods are not served directly—they are stored and then cooked or used. Seal raw chicken breasts and thaw in the refrigerator overnight before grilling or baking. Sealed berries can be used in smoothies straight from the freezer. Coffee beans stay fresh for espresso or drip coffee for up to 3 months when sealed and stored in a cool, dark place. Cooked leftovers, like chili or pasta sauce, can be sealed and reheated in a pot of boiling water for 5–7 minutes until hot.
Variations
- Dry goods: Seal rice, pasta, flour, or nuts in smaller portions (1–2 cups / 150–300 g) to keep them fresh and prevent pantry pests.
- Cheese: Seal hard cheeses like cheddar or parmesan in blocks; the vacuum prevents mold and keeps them fresh for weeks. Soft cheeses should be sealed with a paper towel to absorb moisture.
- Vegetables: Blanch vegetables (e.g., green beans, broccoli) in boiling water for 2–3 minutes, then ice-bath, dry, and seal. This preserves color and texture for up to 1 year in the freezer.
- Sous vide: Use the vacuum sealer to prepare food for sous vide cooking. Seal seasoned chicken or steak with herbs and butter, then cook in a water bath at the desired temperature.
Storage and Reheating
Vacuum-sealed raw meat and poultry can be refrigerated for 3–5 days, or frozen for up to 12 months without freezer burn. Cooked leftovers, once sealed, keep in the refrigerator for 3–4 days or in the freezer for 2–3 months. Sealed dry goods like flour or rice last up to 1 year in a cool, dark pantry. To reheat vacuum-sealed leftovers, drop the sealed bag into simmering water (not boiling) for 5–10 minutes, or open the bag and microwave the contents. Always thaw frozen sealed meat in the refrigerator, never at room temperature. After thawing, cook meat to the USDA FSIS safe minimum internal temperature: whole cuts of beef, pork, veal, and lamb to 145°F (63°C) with a 3-minute rest; ground meat to 160°F (71°C); poultry to 165°F (74°C). Do not reuse vacuum bags that have held raw meat; wash and reuse only for dry goods.
Frequently Asked Questions
Why is my Xiaomi sealer not vacuuming? The most common cause is a dirty or wet sealing strip. Wipe the vacuum channel and sealing strip with a dry cloth. Also check that the bag is placed flat and that the lid is fully closed until both sides click. If the bag is wrinkled, the vacuum cannot pull air properly.
Can I use any vacuum seal bags with the Xiaomi machine? The Xiaomi sealer works with most embossed or textured vacuum seal bags and rolls, but smooth bags without a channel may not seal correctly. For best results, use the bags designed for the Xiaomi machine or any brand labeled “for vacuum sealers” with a textured interior.
How do I make a bag from a roll? Cut the roll to the desired length, then seal one end using the “Seal” function. Make sure the sealed end is straight and free of wrinkles. Leave at least 2 inches (5 cm) of material above the food for the vacuum and seal.
Can I vacuum seal liquids like soup? Yes, but freeze the soup in a tray or muffin tin until solid, then vacuum seal the frozen blocks. Do not attempt to vacuum seal liquid at room temperature—it will be sucked into the machine and damage it.
How long does vacuum-sealed food last? In the refrigerator, raw meat lasts 3–5 days, cooked leftovers 3–4 days, and soft cheeses 1–2 weeks. In the freezer, raw meat and poultry last 9–12 months, vegetables 8–12 months (if blanched), and cooked meals 2–3 months. Dry goods like coffee and flour last 6–12 months.
Why does my seal have bubbles or gaps? This usually happens when there is moisture or food particles on the sealing strip. Clean the strip carefully with a dry cloth, and ensure the bag is completely dry at the open end before sealing. Also, avoid overfilling the bag—leave enough empty space for a clean seal.
