From the orchard to the supermarket shelf, fresh and processed fruits undergo a meticulous journey to ensure they are safe, clean, and appealing to consumers. A critical, yet often unseen, part of this journey involves industrial brush rolls. Far from simple scrubbers, these are precision-engineered tools designed to perform vital tasks in fruit processing lines, directly impacting food safety, quality, and efficiency.

At Shanghai Longguang, we specialize in manufacturing high-performance, food-grade brush rolls that meet the stringent hygiene and performance standards of the modern food industry. Our brushes are trusted partners in helping processors deliver superior products.

Key Applications of Brush Rolls in Fruit Processing

Brush rolls are versatile workhorses, deployed at several stages to prepare fruits for packaging or further processing.

1. Thorough Washing and Cleaning
The first and most crucial step is removing all field contaminants. Fruits arrive from harvest carrying soil, sand, dust, pesticide residues, and even natural waxes.

• How Brushes Help: Our industrial brush rolls work in tandem with water sprays to gently but effectively scrub the surface of apples, oranges, peaches, and root vegetables like potatoes and carrots. The brushing action dislodges stubborn dirt and debris that water alone cannot remove, ensuring a deep and thorough clean.

2. Gentle Peeling and Skin Removal
For fruits that require peeling for canning, freezing, or further processing (e.g., peaches, tomatoes, pears), brush rolls offer a highly efficient and gentle method.

• How Brushes Help: After a brief thermal or lye treatment to loosen the skin, soft food-grade brush rolls gently abrade the surface, removing the peel without damaging the delicate flesh underneath. This mechanical peeling minimizes product loss and waste compared to purely chemical or manual methods.

3. Enhancing Natural Appearance (Polishing)
Consumers are drawn to fruits with a bright, natural shine. Many fruits, like apples and citrus, have a natural wax coating that can become dull during washing.

• How Brushes Help: Specially designed polishing brushes, often made with soft, non-marking fibers, are used to buff the fruit's surface. This restores its natural luster, making it more visually appealing in the store and increasing its perceived value.

4. Efficient Dewatering and Drying
Excess moisture on fruit surfaces can promote microbial growth (mold and yeast), leading to rapid spoilage.

• How Brushes Help: After washing, brush rolls with absorbent or squeegee-like filaments can be used to gently remove standing water from the fruit's surface. This step is critical before packaging or further processing, as it significantly extends shelf life.

The Anatomy of a Food-Grade Brush Roll: Safety First

In food processing, the brush is not just a tool; it's a product contact surface. Its design and materials are governed by strict regulations.

• Hygienic Core Construction: Cores are typically made from high-grade stainless steel (304 or 316) or FDA-compliant polymers that are non-corrosive, easy to clean, and resistant to sanitizing chemicals.

• Food-Safe Filaments: The filament choice is critical for both performance and safety.

  • Abrasive Nylon Filaments: Our nylon filaments can be impregnated with food-safe mineral grit (like silicon carbide) for gentle peeling or scrubbing of tougher-skinned fruits. All materials are compliant with FDA and EU food contact regulations.

  • Soft Polymer Bristles: For polishing and delicate washing, we use non-marking, hygienic polymer bristles that won't damage the most fragile fruit skins.

  • Natural Fiber Bristles: For specific applications, options like white Palmyra fiber are available.

• Hygienic Design Features: We design our brushes to avoid microbe-harboring gaps. This includes smooth surfaces, sealed ends, and construction that allows for easy cleaning-in-place (CIP) or disassembly.
