Conveyors are critical to the food industry, ensuring products move efficiently and safely through each stage of production. From raw ingredient handling to final packaging, these systems maintain high levels of precision and cleanliness, meeting strict industry regulations.
In this guide, we will explore the types of conveyors commonly used in food processing, their key features, and how they contribute to efficient, sanitary operations.
Why are Conveyors Crucial in the Food Industry?
Food safety regulations demand the utmost attention to hygiene. This need makes conveyor systems essential to maintain smooth and sanitary operations. Without the right conveyors in place, the food production line can face serious delays, contamination risks, or both. That’s why it’s important to understand the most common types of conveyors used in the food industry and how they help streamline processes while maintaining cleanliness and safety.
Types of Conveyors: Built for Hygiene and Efficiency
Conveyors used in the food industry are designed with strict sanitary standards. Most are made of stainless steel and have special features to ensure easy cleaning and maintenance. Below, we will explore the most common types of conveyors used in food production, each serving a specific purpose while ensuring that food safety regulations are met.
1. Sanitary Conveyors
Sanitary conveyors are the backbone of the food industry. These conveyors are built to ensure that every part of the system can be easily cleaned and inspected. Here are some of the unique features of sanitary conveyors:
- Stainless steel construction: Most sanitary conveyors are made from stainless steel, which is resistant to corrosion and easy to clean.
- Stand-off bearings: Bearings on these conveyors are stood off from the side frames to allow thorough wash-through, ensuring no water or debris gets trapped.
- Removable belts: Belts on sanitary conveyors can be lifted or easily removed for in-depth cleaning.
Sanitary conveyors are essential for preventing contamination and maintaining the cleanliness of the production environment. The ability to clean every component thoroughly is a critical feature, especially when dealing with raw food products.
2. Thermoplastic and Stainless Steel Bearings
In food processing environments, bearings need to withstand frequent cleaning and exposure to moisture. Stainless steel bearings and thermoplastic housings are often used because of their durability and resistance to rust and other forms of wear.
These components ensure that the conveyor operates smoothly, even in wet or harsh conditions, making them ideal for food industry use.
3. Stainless Steel Motors and Gearboxes
Another important element of sanitary conveyors is the use of stainless steel motors and epoxy-coated or stainless steel gearboxes. These components are built to handle the demanding environment of food processing plants, which involve frequent washdowns and the potential for exposure to corrosive materials.
This type of construction ensures long-lasting durability while also complying with food safety standards. Whether moving raw or packaged food, stainless steel motors and gearboxes ensure reliability.
Conveyor Belt Materials for the Food Industry
Different types of food products require different types of belts, so it’s critical to choose the right one for your specific needs. Some of the most commonly used belt materials in the food industry include:
- Polyurethane belts: These are completely impervious to moisture, making them ideal for food processing environments where liquids are involved.
- FDA-rated belts: These belts are specifically designed for food contact and meet strict FDA or USDA standards. They can handle raw products and are built to move around tight nose bars.
- Tabletop and modular belts: Depending on the product being transported, some food applications require tabletop chains or modular belts. These are commonly used in areas where food is packaged, and the conveyor design includes a wash-through feature to maintain cleanliness.
Applications of Different Conveyor Types
Depending on the product being processed, different conveyors serve specific roles in the food industry:
- Raw Product Handling: For handling raw food items, it’s crucial that all food contact surfaces meet FDA or USDA standards. This includes the belts and the entire conveyor system.
- Packaged Products: When processing packaged food in a washdown area, tabletop chain conveyors are often used. These conveyors feature a wash-through design, ensuring that no debris or liquid gets trapped inside the system.
Keeping It Clean: Essential Features of Food Industry Conveyors
Cleanability is one of the most critical factors when selecting a conveyor for food processing. Food-grade conveyors are designed with the following features to ensure thorough cleaning:
- Trap-free design: Components like spreaders and belts are designed to avoid trapping water or debris, ensuring that every part of the conveyor can be cleaned effectively.
- Removable or liftable parts: Conveyor belts and other components are designed to be lifted or removed, allowing workers to clean hard-to-reach areas and prevent bacterial build-up.
These features ensure that all debris is washed through and nothing is left behind to contaminate the food being processed.
In Summary
Choosing the right conveyor system for your food processing plant is a key factor in maintaining productivity, efficiency, and—most importantly—food safety. By selecting from the most common types of conveyors used in the food industry, such as sanitary conveyors, stainless steel bearings, and food-grade belts, you can ensure that your processes run smoothly while adhering to strict regulatory standards.
