Industrial-Grade Food Melting Furnace: Complete Guide for Manufacturers

1. Specification Models: Choose the Right Furnace for Your Needs

Key Model Differentiators

• Heating Method: Steam heating is ideal for low-temperature melting (e.g., butter) and facilities with existing steam systems; oil jackets offer higher temperature stability for high-melt ingredients (e.g., industrial gelatin); electric heating is suitable for locations without steam/oil infrastructure.

• Capacity: Small models (50–200 L) fit artisanal or small-batch production (e.g., local bakeries), while large models (1000–5000 L) support mass production (e.g., multinational confectionery brands).

• Customization: Manufacturers can request tailored models, such as explosion-proof designs for flammable ingredients (e.g., ethanol-based extracts) or mobile units (with wheels) for flexible factory layouts.

2. Installation Instructions: Pre-Installation Preparation

2.1 Site Requirements

• Space & Layout: Ensure the installation area has enough space for the furnace, plus 1–1.5 meters of clearance on all sides for maintenance, ventilation, and operator access. The floor must be flat (maximum slope: 1°) and capable of supporting the furnace’s weight (e.g., 680 kg for model FMF-500O—reinforce the floor if needed).

• Power Supply: Verify the power supply matches the model’s requirements (e.g., 380V/3PH/50Hz for FMF-500O). Install a dedicated circuit breaker (rating: 1.2× power consumption, e.g., 9.6A for 8.0 kW) and a ground wire (cross-sectional area ≥2.5 mm²) to prevent electrical hazards.

• Utility Connections: For steam/oil/water-heated models, prepare the following:

• Steam: Pressure ≥0.4 MPa, pipe diameter ≥DN40, with a pressure gauge and safety valve.

• Oil/Water: Pipe diameter ≥DN32, with a filter (mesh size ≤50 μm) to prevent debris from clogging the jacket.

• Ventilation & Temperature: The installation area must have natural or mechanical ventilation (airflow ≥5 m³/min) to dissipate heat. Ambient temperature should be 5°C–40°C (avoid direct sunlight or cold drafts) to protect electrical components.

2.2 Tools & Materials Needed

• Tools: Wrench set (10–32 mm), screwdriver set (Phillips/flat-head), level (2m), tape measure (5m), pipe cutter, and torque wrench (0–200 N·m).

• Materials: Food-grade sealant (e.g., silicone compliant with FDA 21 CFR Part 177.2600), insulation tape (for pipes), and stainless steel bolts (M8–M12) for securing the furnace.

• Safety Gear: Heat-resistant gloves, safety glasses, hard hat, and non-slip shoes.

3. Installation Guidelines: Step-by-Step Implementation

3.1 Unpacking & Inspection (30–60 Minutes)

1. Unpack the furnace using a forklift or crane (use the designated lifting points—do not lift by the control panel or heating jacket).

2. Remove all packaging materials (cardboard, foam, plastic) and check for damage: inspect the stainless steel chamber for dents, the control panel for cracked screens, and the heating jacket for leaks.

3. Verify that all accessories are included (e.g., mixing paddle, user manual, spare gaskets) by cross-referencing the packing list. If any parts are missing or damaged, contact the manufacturer immediately.

3.2 Positioning & Securing (1–2 Hours)

1. Use a level to ensure the furnace is placed horizontally—adjust with shims (if needed) until the bubble in the level is centered.

2. Secure the furnace to the floor using stainless steel bolts (M10 for models ≤1000 L, M12 for models >1000 L). Tighten the bolts to a torque of 50–80 N·m to prevent movement during operation.

3. Mark the position of the furnace on the floor (with paint or tape) for future reference (e.g., during maintenance or relocation).

3.3 Utility Connections (2–4 Hours)

1. Power Connection: Turn off the main power supply. Connect the furnace’s power cable to the dedicated circuit breaker—ensure the wires are correctly aligned (L1, L2, L3 for 3-phase; N for neutral; PE for ground). Use a multimeter to test for continuity and avoid short circuits.

2. Heating Medium Connection:

• For Steam-Heated Models (e.g., FMF-50S): Connect the steam inlet pipe to the furnace’s steam port using a food-grade gasket. Install a pressure gauge and safety valve (set to 1.2× maximum steam pressure) on the inlet pipe. Test for leaks by pressurizing the system to 0.4 MPa and applying soapy water to the joints—no bubbles indicate a tight seal.

• For Water/Oil-Jacketed Models (e.g., FMF-200W): Fill the jacket with distilled water (for water) or food-grade thermal oil (for oil) until the level reaches the “MAX” mark on the sight glass. Connect the inlet/outlet pipes to the jacket, ensuring the flow direction matches the manufacturer’s labels (inlet at the bottom, outlet at the top).

3. Control Panel Setup: Turn on the main power and initialize the control panel. Set the language, date, and time via the HMI touchscreen. Calibrate the temperature sensor using a certified thermometer (adjust the offset in the settings menu if there is a discrepancy).

3.4 Testing & Commissioning (1–2 Hours)

1. Dry Run: Run the furnace without ingredients for 30 minutes. Set the temperature to 80°C and monitor the heating rate— it should reach the set temperature within 15–20 minutes (varies by model). Check for abnormal noises (e.g., grinding from the mixing paddle) or overheating (touch the outer jacket— it should be warm but not scalding).

2. Load Test: Add a small batch of ingredients (e.g., 10 kg of butter for FMF-50S) and run a full melting cycle. Verify that the temperature remains stable (±1°C), the mixing paddle operates smoothly, and the ingredient melts uniformly (no clumps).

3. Safety Test: Simulate faults to ensure safety features work:

• Over-temperature: Set the temperature to 250°C (exceeding the model’s maximum range)—the alarm should sound, and the heating system should shut down within 10 seconds.

• Power Failure: Turn off the main power during operation—the furnace should save the current cycle data and resume once power is restored.

4. Documentation: Record all test results (temperature, time, pressure) in the installation log. Obtain a signed commissioning certificate from the technician to confirm compliance with standards.

4. Product Applications: Where Industrial-Grade Food Melting Furnaces Excel

4.1 Confectionery Industry

• Chocolate Melting: Models like FMF-200W (water jacket, 30°C–180°C) melt chocolate at 45°C–50°C (dark chocolate) or 40°C–45°C (milk chocolate), preventing scorching and preserving flavor. The uniform heating ensures the chocolate has a smooth texture, critical for coating candies or molding chocolate bars.

• Gummy Production: Furnaces melt gelatin (at 60°C–70°C) and mix it with sugar syrups—models like FMF-500O (oil jacket) maintain stable temperatures to avoid gelatin clumping, ensuring consistent gummy elasticity.

4.2 Dairy Processing

• Butter Melting: Small to medium models (e.g., FMF-50S) melt butter at 40°C–45°C for use in ice cream mix or pastry dough. The hygienic stainless steel chamber prevents cross-contamination, meeting dairy safety standards (e.g., EU Regulation 853/2004).

• Cheese Spread Production: Large models (e.g., FMF-1000I) melt processed cheese (at 70°C–80°C) and blend it with emulsifiers— the indirect heating method avoids burning, ensuring a creamy spreadable texture.

4.3 Meat & Poultry Processing

• Lard/Tallow Melting: Models like FMF-2000H (hybrid heating) melt lard (at 50°C–60°C) or tallow (at 45°C–55°C) for use in sausage casings or burger patties. The high capacity supports mass production, while the CIP (Clean-in-Place) system simplifies cleaning between batches.

• Gelatin Binder: Furnaces melt animal-based gelatin (at 60°C–70°C) for use as a binder in restructured meats (e.g., chicken nuggets), ensuring the meat holds its shape during cooking and freezing.

4.4 Frozen Food & Ready-to-Eat (RTE) Meals

• Sauce Melting: Models like FMF-500O melt tomato sauce (at 80°C–90°C) or cheese sauce (at 75°C–85°C) for frozen pizzas or lasagnas. The furnace’s ability to maintain temperature ensures the sauce remains fluid during filling, preventing clogs in packaging machines.

• Topping Preparation: For frozen desserts (e.g., ice cream sundaes), furnaces melt chocolate or caramel toppings (at 50°C–60°C) and keep them warm until packaging, ensuring consistent topping quality.

4.5 Health Food & Nutraceuticals

• Plant-Based Fat Melting: Models like FMF-50S melt coconut oil or avocado oil (at 30°C–40°C) for protein bars or energy balls. The precise temperature control preserves the oil’s nutritional value (e.g., omega-3 fatty acids).

• Edible Wax Coating: Large models (e.g., FMF-5000C) melt beeswax or carnauba wax (at 60°C–70°C) for coating vitamin tablets or herbal supplements. The wax forms a protective layer that extends shelf life and prevents moisture absorption.
