Roller conveyors use a series of rollers to move products, making them well-suited for handling rigid containers, boxes, and pallets. They can be gravity-powered, relying on gravity to move the product, or powered, providing a more controlled and consistent flow.
The Efficient Screw Conveyor
Also known as auger conveyors, screw conveyors use a rotating screw to move bulk materials such as powders, grains, and wet ingredients. Selecting the appropriate material for the screw and housing is essential to ensure compatibility with the product and prevent contamination.
The Gentle Vibratory Conveyor
Vibratory conveyors utilize vibration to move product along a trough. This gentle handling makes them ideal for applications involving screening, sorting, and distribution, particularly for fragile or easily damaged food products.
The Vertical Solution: Bucket Elevators
Bucket elevators efficiently elevate bulk materials vertically using a series of buckets attached to a belt or chain. They are commonly used for handling grains, seeds, and other granular products.
The Materials That Make a Difference in Food Grade Conveyor
The materials used in the construction of food-grade conveyors are critical to their performance and safety.
The Power of Stainless Steel
Stainless steel is a mainstay in food processing equipment due to its exceptional corrosion resistance, durability, and cleanability. Grades such as 304 and 316 are commonly used, with 316 offering superior resistance to chlorides and other harsh chemicals.
The Versatility of Plastics
Various types of plastics, including polyurethane (PU), polyvinyl chloride (PVC), polyethylene (PE), and Acetal, are used in food-grade conveyor construction. Each plastic offers a unique set of properties, such as flexibility, chemical resistance, and temperature range, making them suitable for specific applications.
Coatings and Finishes Enhance Hygiene
Coatings and finishes play a vital role in enhancing the hygienic properties of food-grade conveyors. Teflon coatings can reduce friction and prevent products from sticking, while antimicrobial coatings can inhibit the growth of bacteria.
Key Design Features for a Hygienic Food Grade Conveyor
Beyond the materials used, the design of a food-grade conveyor is crucial for ensuring hygiene and ease of cleaning.
Prioritizing Easy Cleaning and Sanitation
Food Grade Conveyor should incorporate sloped surfaces for efficient drainage, quick disassembly for thorough cleaning, and a design that minimizes dead spots and crevices where food particles can accumulate.
Adhering to Hygienic Design Principles
Following guidelines from organizations like EHEDG (European Hygienic Engineering & Design Group) is essential for ensuring that the conveyor is designed for optimal hygiene. This includes careful consideration of welding, joints, and surface finishes.
Belt Tracking and Tensioning Matter
Proper belt alignment is crucial for preventing contamination and wear, while adjustable tensioning systems ensure optimal performance and longevity.
