Pet & Animal Food

Modern pet food production combines nutrition, functionality and convenience, with strict expectations on hygiene and product consistency at every stage. Rospen designs and supplies weighing, metering and material handling systems that accurately manage powders, granules and fragile pieces for pet food lines, from raw ingredient reception through to mixing, extrusion and coating.

Clean, Controlled Handling Of Pet Food Ingredients

Pet food formulations increasingly mirror human nutrition, using specialty proteins, fibres, minerals and functional additives that must be handled hygienically. Rospen’s food‑sector expertise supports safe, controlled handling of these ingredients in both dry and semi‑moist processes.

• Systems for handling flours, starches, proteins, minerals and other powdered ingredients, drawing on experience with cereals and snack foods.
• Options for sieving and conditioning of raw ingredients to support consistent feed into mixers and extruders.
• Hygienic equipment layouts with good access to support regular cleaning between recipes and protein sources.

Stable Recipes For Kibbles And Treats

Consistent kibble quality and functional performance depend on precise dosing of major and micro‑ingredients into mixing and extrusion processes. Rospen’s weighing and feeding technologies are designed to deliver repeatable accuracy on pet food lines.

• Loss‑in‑weight feeders, weigh belts and vibratory feeders to dose powders, small particulates and additives into batch and continuous mixers.
• Solutions suitable for feeding into extruders and pre‑mix systems, supporting both dry and semi‑moist pet food production.
• Integration with recipe management and automation systems to maintain consistent formulations and provide traceable production data.

Protecting Product Quality And Reducing Waste

Pet foods often include fragile kibbles, inclusions and coated products that can be damaged if handled too aggressively. Rospen’s experience with fragile cereals and snack foods supports gentle transfer and controlled rework of out‑of‑spec material.

• Conveying solutions for fragile kibbles and inclusions, based on proven approaches for cereals and snack products.
• Systems to collect, condition and reintroduce off‑spec material where appropriate to the process, helping reduce waste and protect yield.
• Configurations that manage dust while limiting impact and abrasion on finished products.

Fast Cleaning Between Recipes

Pet food plants often run multiple recipes, sizes and species‑specific products on shared lines, making fast, effective cleaning essential. Rospen develops equipment features that simplify changeovers while supporting hygienic operation.

• Fast‑strip arrangements and easy‑access designs on feeders and hoppers, developed originally for flavour applications in the snack food sector.
• Smooth contact surfaces and layouts that minimise product retention and support dry or wet cleaning regimes.
• Dust‑tight equipment options to improve housekeeping and support food safety for both operators and end products.
