Our RSV series sous vide cookers feature ±0.1°C high-precision temperature control, IPX7 water resistance, quiet water circulation, and APP smart connectivity, suitable for household and export markets worldwide. Based on the universal standards of RUBOW models, we provide an authoritative and practical operation guide covering the entire process from equipment setup to food cooking, usable by both beginners and commercial users.

Sous Vide is a globally popular precision cooking technology that uses constant-temperature circulating water bath + vacuum sealing to heat food evenly at a low and steady temperature. It completely eliminates “overcooked outside, undercooked inside” and dry, tough texture, helping you easily make restaurant-quality tender and juicy dishes at home.


 

1. Preparations: Required Tools & Food Preparation

1.1 Core Equipment & Container

•  
  • Sous Vide Cooker: Stick-type circulation heater (household/commercial universal), must support precise temperature control (±0.5°C ideal), 360° water circulation, and dry-boil alarm.
  • Water Container: Stainless steel pot, food-grade PP container, or glass tank (depth ≥12cm). Avoid low-quality plastic that may release harmful substances when heated. Capacity must fully submerge food and allow machine installation.
  • Auxiliary Tools: Vacuum sealer + food-grade vacuum bags (or zipper bags), paper towels, heat-resistant plastic wrap / aluminum foil, food thermometer (optional for calibration).
  • Food Preprocessing (Critical Steps)

1.Thaw & Dry: Thaw frozen food in the refrigerator. Wipe all food completely dry with paper towels to avoid water inside the vacuum bag that affects heat transfer.

2.Seasoning:

•  
  • Basic: Salt, black pepper, minced garlic, rosemary, thyme and other dry spices (avoid too much liquid sauce, which weakens vacuum sealing).
  • Flavor boost: Add 1–2 spoons of olive oil, butter, lemon juice, or herbs; vacuum sealing concentrates flavor.

3.Vacuum Sealing (Core):

•  
  • Method 1 (Vacuum Sealer): Place food + seasonings in a vacuum bag, leave 2–3cm for sealing. Vacuum until the bag tightly fits the food (no air left), then heat-seal firmly.
  • Method 2 (No Sealer): Place food in a zipper bag, slowly submerge in water (keep top above water), use water pressure to remove air, then seal quickly (no water inside).
  • Note: Punctured or loose sealing causes water intrusion and poor texture; check seal before cooking.
    
    

2. Standard Operating Steps (Universal Version)

Step 1: Install & Secure the Cooker

• Loosen the clamp, insert the heating rod vertically into the container. Ensure the heating part is fully submerged and water level is between MIN and MAX marks.
• Tighten the clamp clockwise to fix the machine stably (no tilting or shaking to prevent dry burning).

Step 2: Add Water & Power On

• Fill the container with room-temperature water (no pre-heating needed). Connect power; the machine enters standby mode.
• Some models support °C / °F switch; set to °C for daily use (machine saves settings).

Step 3: Set Temperature & Time (Core)

• Temperature: Press TEMP and use +/- buttons or dial to adjust (reference: steak 52–60°C, chicken breast 60–65°C, salmon 50–54°C).
• Time: Press TIME to set hours and minutes (regular food: 1–4 hours; thick cuts / tough meat: 6–12 hours).
• Advanced: Smart models support WiFi / Bluetooth APP control — select food type, thickness, doneness; auto-match parameters without manual calculation.

Step 4: Start Heating & Add Food

• Confirm settings and press START; the machine heats up and shows real-time water temperature.
• Important: Wait until water reaches target temperature and stabilizes before adding sealed food (cold water causes uneven heating).
• Ensure food is fully submerged (use weight if floating). Cover surface with plastic wrap to reduce evaporation and heat loss.

Step 5: During Cooking & Finishing

• No monitoring or stirring needed — 360° circulation heats evenly. Low-level alarm reminds you to add warm water if needed.
• When finished: buzzer alerts → press STOP → unplug → use tongs to remove food (avoid burns).

Step 6: Sear for Aroma & Color (Recommended)

Sous vide food is fully cooked and tender but lacks surface crispness; quick high-heat searing is recommended:

• Meat: Heat pan until smoking, add butter / olive oil, sear 30–60 seconds per side for golden Maillard crust.
• Seafood / Vegetables: Torch surface or broil in oven at 220°C for 5 minutes to enhance flavor.

4. Safety & Maintenance

4.1 Safety Warnings

Do NOT run dry or below MIN water level — damages heating elements.

Not recommended: Beans, mushrooms, untreated raw meat (low temp cannot destroy toxins, risk of food poisoning).

Uneaten food: Cool immediately in ice bath, refrigerate ≤3 days or freeze ≤1 month. Reheat at (original temp –10°C) for 30 mins.

4.2 Machine Maintenance

After each use: Unplug and cool down. Wipe body with damp cloth (do not submerge entire unit or wash control panel). Clean scale on heater with vinegar + water soak for 10 mins.

Long-term storage: Dry completely, store in dry, ventilated area to avoid circuit damage.

5. FAQ for Beginners

Q: Why is there blood inside after cooking?

A: Insufficient temperature/time or uneven heating. Extend cooking by 10–20 minutes.

Q: What if water enters the vacuum bag?

A: Poor sealing. Safe to eat but texture affected; check seal carefully next time.

Q: Temperature reading is inaccurate?

A: Calibrate with food thermometer. If error >1°C, contact after-sales service.

With these standard steps, your sous vide cooker will become a reliable kitchen tool. Whether for home cooking or commercial catering, you can consistently make tender, juicy, fail-proof precision dishes and unlock the secret of professional gourmet cooking.
