What are the key points for maintaining a fully automatic sandwich cookie machine?
Fully automatic sandwich cookie equipment is a key piece of equipment in cookie production. It integrates pressing, shaping, filling injection, and baking functions, enabling efficient and stable production of sandwich cookies. It typically consists of a mixing device, a shaping device, a filling injection device, an oven, a cooling device, and a packaging device. These devices are controlled by a CPU module and driven by a back-mounted motor, featuring a compact structure and a high degree of automation.
The working principle of fully automatic sandwich cookie equipment is as follows: the mixing device evenly mixes the cookie ingredients; the shaping device presses the ingredients into cookie shapes; then, the filling injection device evenly injects the filling between two cookies; finally, after baking in the oven and cooling by the cooling device, the cookies are packaged by the packaging device to obtain the finished sandwich cookies.
The following are some maintenance points for fully automatic sandwich cookie equipment:
I. Daily Maintenance
Cleaning
Machine Body Cleaning: After the equipment has finished running, promptly clean the surface of the machine to remove cookie residue, sugar powder, and other debris. For stubborn stains, wipe with a damp cloth. Use a small amount of neutral detergent, but be careful to avoid getting detergent inside critical components of the equipment.
Mold Cleaning: The mold is a key component for shaping sandwich cookies. Clean the mold thoroughly after each use to remove any residue. The mold can be disassembled, washed with warm water and a soft brush, then air-dried or wiped dry with a clean towel. Ensure the mold surface is clean and free of foreign objects to avoid affecting the shape and quality of the next batch of cookies.
Conveyor Belt Cleaning: The conveyor belt easily gets contaminated with oil and cookie crumbs during cookie transport. Wipe the conveyor belt surface regularly with a damp cloth to remove dirt and crumbs. If there is oil on the conveyor belt, use a specialized cleaner, but be careful to avoid cleaner residue to prevent food safety issues.
Lubrication and Maintenance:
Mechanical Transmission Parts: Inspect the mechanical transmission parts of the equipment, such as chains, gears, and pulleys. Add an appropriate amount of lubricating oil or grease regularly according to the equipment's instruction manual. Generally, check weekly or bi-weekly to ensure good lubrication of the transmission parts and reduce wear and noise. Sliding Guide Rails: Keep the sliding guide rails on the equipment clean and well-lubricated. Apply a dedicated guide rail lubricant and check and lubricate at least once a month to ensure smooth sliding and prevent jamming.
Electrical System Inspection
Wiring Inspection: Before starting the machine each day, check the electrical wiring for damage, looseness, etc. Pay special attention to the power cord, motor wiring, and control circuits. Repair or replace any wiring problems promptly to avoid safety accidents such as leakage or short circuits.
Electrical Component Inspection: Regularly inspect all electrical components on the equipment, such as switches, buttons, contactors, and sensors, to ensure they are working properly. For frequently used buttons and switches, check the wear of the contacts; replace any worn ones promptly. Also, check the position and sensitivity of sensors to ensure the normal operation of the equipment's automated control functions.
II. Regular Maintenance
Mechanical Component Inspection and Adjustment
Mold Calibration: Regularly inspect and calibrate the molds to ensure all components are securely installed and correctly spaced. Mold calibration is generally performed monthly using professional measuring tools such as calipers and micrometers to measure the dimensional accuracy of the molds. Any deviations should be adjusted promptly to ensure the size and shape of the cookies meet requirements.
Transmission System Inspection: A comprehensive inspection of the equipment's transmission system should be conducted periodically (e.g., every three months), including chain tension, gear wear, and belt tension. For chains, adjust tension or replace worn links as needed. For gears, check tooth wear; replace those with severe wear. For belts, adjust or replace belts if loose or cracked to ensure efficient and stable operation of the transmission system.
Mixing System Inspection: For the mixing system of the sandwich cookie equipment, regularly check the wear of the mixing blades and the tightness of the fixing screws. Replace severely worn blades promptly to ensure mixing effect and uniformity of the filling. Also, check the operating status of the mixing motor to ensure smooth operation without abnormal vibration or noise.
Cooling System Maintenance
Radiator Inspection: Regularly inspect the equipment's cooling system, especially the radiator. Check the radiator surface for dust accumulation. Clean any dust promptly to ensure effective heat dissipation. Generally, clean the radiator quarterly. Use compressed air to blow away dust or gently brush it with a soft brush.
Cooling Fan Inspection: Check the cooling fan's operation to ensure the blades rotate freely without jamming. Also, check the fan motor for proper functioning. Repair or replace any faulty motors promptly. Proper cooling fan operation is crucial for maintaining stable equipment temperature, especially during long periods of continuous production.
Baking System Maintenance
Heating Element Inspection: Regularly inspect the baking system's heating elements, such as heating wires and gas burners, to ensure they are functioning correctly. For ovens with heating wires, check for breaks or oxidation. Replace any damaged wires immediately. For gas burner ovens, check the burner's ignition, flame color, and size. Adjust or repair any issues promptly.
Temperature Sensor Calibration: Calibrate the temperature sensor periodically (e.g., every six months) to ensure accurate and reliable temperature measurements. Professional thermometers and temperature sensors can be used for comparison and calibration. If there is a deviation, the temperature sensor should be adjusted or replaced in time to ensure the accuracy of temperature control during the baking process.
