1.5–2.0T/H Two Screw Extruder in Germany

Why the Customer Chose a Standalone Twin Screw Extruder

Before contacting RICHI, this company relied on smaller single screw extruders at a partner plant, but they struggled to handle certain high-protein or high-fat recipes that are increasingly popular with German pet owners. The company’s product developers needed a machine that could produce uniform kibble with better control over moisture content, cooking temperature and starch gelatinization.

They did not need a full new feed line because they already have reliable milling, mixing and coating equipment in place. Instead, their main goal was to install a single robust two screw extruder as the core cooking unit, which could slot seamlessly into their current setup.

After reviewing multiple options, the company chose the RICHI SPHS120*2 two screw extruder. It offered the ideal balance for their mid-range volumes and recipe types—giving them enough capacity to meet current contracts with room to scale, but without oversizing.

Machine Selection and Technical Parameters

Local Raw Materials and Typical Formulas

• High-quality poultry meal and fish meal (30–40%) for protein content
• Corn, wheat or potato flour (40–50%) for starch, adjusted to recipe type
• Rendered animal fat and plant oils (5–10%) for energy and palatability
• Added minerals, vitamins, probiotics and plant extracts to meet nutritional claims

A typical product run might be 60% grains or potato base with 30% protein meal and 10% oils, vitamins and functional ingredients. The two screw extruder ensures that the final kibble is properly cooked, extruded and expanded, achieving the desired texture and shelf stability.

Advantages of the Two Screw Extruder for Pet Food

• Wider Recipe Range: Twin screw design provides higher mixing and shear force, perfect for grain-free or high-protein kibble which is otherwise difficult to process uniformly
• Stable Product Quality: Consistent cooking and pressure yield even expansion and shape. This is critical for premium brands promising digestibility and visual appeal
• Flexible Output: With adjustable screw elements, operators can switch between dog food, cat food, or small mammal kibble without major downtime
• Energy Efficiency: In-house extrusion cuts waste and lowers logistics costs
• Traceability and Control: By managing extrusion internally, the company fully controls cooking temperature, moisture, and additives—key for meeting German and EU feed safety standards

Practical Integration in an Existing Plant

The SPHS120*2 two screw extruder connects directly to the company’s existing hammer mill, ribbon mixer and automatic packaging line. Raw materials arrive from local suppliers and are ground to the required particle size, then mixed with liquids and micro-ingredients.

The preconditioner brings the mix to optimal temperature and moisture. Inside the twin screw barrel, ingredients are cooked, kneaded and forced through the die plate to create uniform shapes. Finished kibble goes through a dryer, then a coating drum where fats and palatants are added.

Operator Training and Start-Up Support

• Supervised on-site installation to integrate the extruder safely into the existing plant
• Delivered training workshops on screw arrangement, recipe trials and die plate changes
• Shared maintenance best practices to extend machine lifespan and minimize unexpected downtime

Even after commissioning, our service team provides remote monitoring assistance and can quickly supply wear parts when needed.

Regulatory and Market Compliance

The German pet food sector operates under tight EU feed hygiene laws. Detailed batch tracking, clear labeling, and accurate nutrient levels are all mandatory. With the new two screw extruder, the customer gains full batch control, data logging, and adjustable process parameters to meet these standards.

It also positions them well for certification under the International Pet Food Certification (IPFC) and other quality schemes demanded by large retailers.

Preparing for Future Expansion

The SPHS120*2 twin screw extruder is not the end of the road. If market demand keeps rising, the company can easily add a second extruder or shift to a larger model like the SPHS150*2. The current extruder can also handle limited runs of floating fish feed—opening potential for new products in the German hobby aquaculture segment.

Because the company runs various brands under private label deals, this flexibility supports quick product changes and short run times—advantages that contract manufacturers could never match as cost-effectively.
