Food Rolling and Kneading Machine – Application Scope, Installation Guide, Energy-Saving Effect & Maintenance Cycle

1 Application Scope: Versatile Solutions for Diverse Industries

1.1 Bakery and Pastry Industry

1.2 Meat Processing Industry

1.4 Pet Food and Health Food Industry

2 Installation Guide: Ensure Stable and Safe Operation

2.1 Pre-Installation Preparation

• Site Requirements: Choose a flat, hard concrete floor with a bearing capacity of ≥500kg/m². Ensure at least 1.5m of clearance around the machine for operation and maintenance. The environment should be dry (humidity ≤85%) and well-ventilated, away from direct sunlight and heat sources.

• Power Supply: Prepare a dedicated circuit with voltage matching the machine’s rating (220V/380V) and a leakage protector (rated current 1.2 times the machine’s maximum current). The grounding resistance must be ≤4Ω to ensure electrical safety.

• Auxiliary Equipment: Prepare a water source (for cleaning) and a drainage system near the machine. For industrial models, ensure compatibility with automatic feeding and discharging conveyors.

2.2 Installation Steps

1. Unpack and inspect: Remove the machine from the packaging, check for damage during transportation, and verify that all parts (manual, tools, spare parts) are complete.

2. Position the machine: Use a level to adjust the machine’s feet, ensuring it is stable and horizontal (error ≤0.5mm/m) to prevent vibration during operation.

3. Connect power and utilities: Connect the power cord to the dedicated circuit, and connect the water inlet and drainage pipes (if applicable). Ensure all connections are tight and leak-proof.

4. Test run: Turn on the power, run the machine empty for 30 minutes, and check for abnormal noise, vibration, or parameter errors. Test with a small batch of materials to verify performance.

3 Energy-Saving Effect: Reduce Operational Costs

3.1 Core Energy-Saving Technologies

• Inverter Motor: The inverter motor adjusts its speed based on the load, reducing energy consumption by 25-35% compared to fixed-speed motors. For example, a 1000kg/h industrial model consumes only 8-10kW/h, saving 3-4kW/h per hour of operation.

• Optimized Mechanical Structure: The roller design reduces friction, and the high-efficiency gearbox minimizes energy loss. The machine’s transmission efficiency reaches 95%, higher than the industry average of 85%.

• Intelligent Control: The PLC system automatically stops the machine when no materials are detected, avoiding idle energy waste. It also optimizes processing time based on ingredient type, reducing unnecessary operation.

4 Maintenance Cycle: A Comprehensive Schedule

4.1 Daily Maintenance (15-20 Minutes)

• Clean the inner chamber, rollers, and feeding hopper with warm water and food-grade detergent. Rinse thoroughly and dry to prevent rust.

• Check for food residue in the machine’s crevices and remove it with a soft brush.

• Inspect the emergency stop button and safety interlock to ensure they work properly.

• Record the machine’s operation time, batch number, and any abnormal conditions in the logbook.

4.2 Weekly Maintenance (1-2 Hours)

• Lubricate the gearbox, roller bearings, and conveyor chain with food-grade lubricating oil. Wipe off excess oil to prevent contamination.

• Check the roller alignment—if misaligned, adjust the adjusting bolts to ensure even pressure.

• Clean the air filter (for models with cooling systems) to ensure efficient heat dissipation.

• Test the PLC control system by running a test program to verify parameter accuracy.

4.3 Monthly Maintenance (2-3 Hours)

• Inspect the motor’s temperature rise during operation—if it exceeds 40℃, check for overload or poor ventilation.

• Tighten all electrical terminals to prevent loose connections and overheating.

• Check the hydraulic system (if applicable) for leaks and top up hydraulic oil if needed.

• Calibrate the pressure sensor and timer to ensure accurate processing parameters.

4.4 Quarterly and Annual Maintenance

• Quarterly: Disassemble the roller bearings for inspection, clean them, and replace if worn. Check the gearbox for oil contamination and replace the oil if necessary.

• Annual: Conduct a comprehensive overhaul, including motor testing (insulation resistance, speed), gearbox inspection (tooth wear), and replacement of aging parts (seals, filters, belts). Invite professional technicians to perform a performance test and calibration.
