Small DC geared motors, with their small size, high torque, convenient speed adjustment, and simple control, are widely used in food processing machinery. They are mainly used in workstations where a certain level of force, speed, and precision is required, but high power is not necessary.
Here are some specific application scenarios in various types of food processing machinery:
1. Packaging and Dispensing Equipment
This is one of the most widely used areas.
· Metering and Filling: Used for precise metering and filling of liquids (such as juice, soy sauce, and cooking oil) and small particulate solids (such as candy, nuts, and coffee beans). The motor drives a pump, screw, or rotary valve to achieve quantitative output.
· Bag Forming-Filling-Sealing Machine: Controls the traction, feeding, and bag making of the film, as well as subsequent opening, filling, and sealing actions.
· Labeling Machine: Drives the conveyor belt and rotary table, and precisely controls the raising and lowering of the labeling head and the peeling and pasting of the label paper.
• **Inkjet/Coding Machines:** Drive ink rollers or printheads for precise movement, printing dates and batch numbers on product packaging.
2. **Processing and Handling Equipment:**
• **Slicing/Dicing Machines:** Drive feed rollers or propulsion mechanisms to push ingredients (such as vegetables, meats, bread) at a constant speed towards rotating blades.
• **Mixing and Mixing Equipment:** Provide appropriate mixing speeds and torque in small mixers, emulsifiers, or seasoning mixers.
• **Conveying and Lifting Equipment:** Drive small conveyor belts, elevators, or distributors in the production line to move food from one workstation to another.
3. **Food Service and Retail Equipment:**
• **Vending Machines:** Drive spiral pushers (for snacks and bottled beverages) or shelf-pushing mechanisms to automatically drop goods.
• **Coffee and Beverage Machines:**
• Drive water pumps for water supply.
• Drive coffee grinders for grinding coffee beans.
• Control pumps for dispensing syrups, milk, and other ingredients.
• Ice Cream Machine: Drives the mixing scraper (ensuring even freezing) and the extrusion pump (for making soft-serve ice cream).
• Marshmallow Machine: Drives a core rotating candy-spinning head to create filaments from melted sugar syrup using centrifugal force.
4. Specialty Food Equipment
• Chocolate Fountain Machine: Drives a central spiral pump to continuously deliver melted chocolate to the top and allow it to flow down.
• Candy/Pastry Decorating Machine: Precisely controls the movement of piping tips or chocolate pens for drawing and writing.
• Noodle Machine/Pastry Press Machine: Drives rollers to press and shape dough.
Why Choose a Small DC Geared Motor?
In these applications, this type of motor is chosen primarily for the following advantages:
1. High Torque, Low Speed Operation: The gearbox converts the motor’s high-speed, low-torque output into the low-speed, high-torque required by the equipment, making it ideal for scenarios requiring force, such as pushing, squeezing, and mixing.
2. High Controllability: Smooth stepless speed regulation can be achieved through simple voltage adjustment or PWM (Pulse Width Modulation), making it easy to integrate with PLCs or microcontrollers for automated control.
3. Compact Size: Ideal for integration into compact food processing machinery.
4. Rapid Start/Stop: Fast response, improving production cycle time and precision.
5. Cost-Effective: Lower cost compared to servo motors and stepper motors while meeting performance requirements.
Important Note: Food-Grade Requirements
Motors used in food processing machinery, especially those that may come into contact with food or be exposed to food environments (moisture, oil mist, flour dust, etc.), typically require special design:
• Protection Rating: Typically requires IP54, IP65, or higher for dust and water resistance.
• Materials and Surface Treatment: The housing may be made of stainless steel or treated with a special anti-corrosion coating.
• Lubricant: The grease inside the gearbox must be food-grade (e.g., compliant with NSF H1 standards) to prevent food contamination in case of leakage.
• Certification: In some stringent markets, compliance with electrical safety certifications such as CE and UL may be required.
In summary, small DC geared motors are indispensable power components in the automation, miniaturization, and intelligentization processes of the modern food industry, spanning almost the entire food supply chain from production and processing to packaging and sales.
