250mm Metal Detectable PBT Food Brush

This is a manual hand brush made for cleaning food-contact surfaces on processing and packaging lines. The working end is a rectangular PBT bristle set about 60 mm wide, set into a polypropylene handle and base. The 250 mm overall length keeps the operator’s hand close enough for controlled scrubbing on tables, conveyors, hoppers, and machine frames without being a long-reach tool.

The bristles do the actual cleaning: they carry detergent and hot water into the residue, loosen it from the surface, and move it toward the rinse stream. PBT is selected because it is stiff enough to push through grease and dough films while remaining softer than stainless steel, and because its low water absorption keeps it functional during long washdown sessions.

The metal-detectable formulation is built into the bristle material itself, not applied as a coating. If a bristle breaks away, the entire fragment retains the detectable property. In the standard configuration, the PP handle is not metal detectable; a metal-detectable PP handle can be specified when full-brush detection is required.

This brush is designed for manual cleaning as part of a larger hygiene sequence. It does not replace CIP systems, foam cleaning, or sanitizing steps, and it should not be used on surfaces where loose bristle fragments could enter product zones without passing a detector or screen.

The values below describe the standard configuration. Bristle diameter, trim length, handle form, and color can be changed for large projects without changing the basic cleaning principle.

Short-term temperature is for intermittent hot-water or steam exposure against the bristle face. Continuous operation above 100°C shortens the usable life of both PBT and PP and is not recommended.

The brush fits food manufacturing, commercial food preparation, and packaging environments where visible product residue has to be removed from open equipment surfaces between production runs or during changeovers.

• Bakery and snack lines: scraping dough, flour, and sugar residue from mixer bowls, dough troughs, divider tables, cooling conveyors, and sheet pans.
• Meat and poultry processing: breaking up fat, protein, and smear on stainless cutting tables, deboning stations, tray wash areas, and machine side panels.
• Dairy and beverage filling: clearing product film and dried splash from filling head housings, conveyor side guides, cappers, and tank exteriors.
• Confectionery and chocolate: loosening syrup, chocolate, and deposited sugar from cooling tunnels, troughs, belt edges, and packaging machinery frames.
• Central prep and food service: cleaning prep tables, racks, transport trays, and work surfaces that carry fats, starches, and sauce residues.

The rectangular face is most productive on flat or lightly curved surfaces. Narrow channels, pipe interiors, corners, and deeply recessed equipment features need a different brush geometry.

Check the access space first. The brush face is 60 mm wide; if the equipment has gaps, rails, or guard slots narrower than about 60 mm, the bristle set will not reach the surface. In that case, specify a narrower head or use a channel or detail brush for those areas.

Confirm the detection requirement with your quality team. Metal-detectable PBT addresses bristle fragments, but detection only works if the product passes a working metal detector or X-ray unit calibrated to the fragment size your plant considers critical. If the handle is also at risk of breaking into product, specify a metal-detectable PP handle so the entire tool is detectable.

Match the bristle firmness to the residue. PBT is appropriate for wet, fatty, starchy, and lightly dried product deposits. It will not cut through baked-on carbon, polymerized oil, or heavy mineral scale; those situations call for a pre-soak, hot water pressure, or a different mechanical tool before brushing.

Check the washdown temperature. Short exposure up to 134°C is acceptable, but continuous hot immersion or repeated autoclave cycles will degrade the bristles and handle faster. If your process maintains equipment surfaces above 100°C for long periods, discuss material options with us before ordering.

Consider operator handling. The 250 mm overall length is balanced for close, controlled scrubbing. If operators need more reach behind guard rails or into deep hoppers, ask about extended handles or an angled head. If the brush will be hung in a controlled tool shadow board, add a hanging hole or molded clip to the handle.

Choose a different brush when the task is aggressive surface preparation, rust removal, or confined internal passage cleaning. A stainless wire brush or an abrasive pad can remove deposits PBT cannot, and a tube or bottle brush is better for bores and small openings.

Yes. The standard configuration is a starting point. For food plant programs and distributor private labels, we adjust the brush to the equipment, residue, and control plan that will actually be used.

Common requests include:

• Overall length, handle angle, ergonomic grip shape, hanging hole, or molded hanging loop
• Brush head width, head depth, and bristle trim length for specific equipment gaps
• PBT filament diameter and stiffness for lighter or heavier scrubbing demand
• Metal-detectable PP handle or base when full-brush detection is required
• Custom brush color for zone coding, shift identification, or brand requirements
• Embossed or laser-marked tool numbers, plant codes, or distributor branding
• Packaging by unit, bag, box, or color-coded kit

To define the right configuration, send us the equipment type, surface material, residue description, cleaning chemical and concentration, washdown temperature, metal detector type and sensitivity, and the expected replacement cycle. A drawing or photo of the area helps us confirm the geometry. If your project requires material declarations, detection validation samples, third-party inspection, or specifications to support a supplier qualification file, we can assist with those requirements during the customization process.
