Cat Kibble Low Temperature Belt Dryer in France

The company produces about 6,000 tons annually of premium cat food. Their grain-free line is formulated specifically for feline health.

Sophie looked for a drying system that could operate at 70-80°C (not 120-150°C) to preserve heat-sensitive nutrients. She found the DHG-1000 belt dryer from RICHI.

From the belt dryer table, the DHG-1000 cat kibble low temperature belt dryer (electrically heated) was selected. Why this model?

• Low temperature: 70-80°C operating range – preserves taurine and other heat-sensitive amino acids
• Gentle airflow: No high-velocity air that can damage kibble surface
• 5-layer design: Extended drying time at low temperature
• Uniform drying: Consistent moisture throughout each kibble
• Energy efficient: Recirculates hot air – lower operating cost

Sophie chose the electric model because their facility had no steam boiler. The DHG-1000 runs on electricity only – clean and simple.

What He's Drying – Grain-Free, High-Protein Cat Kibble

French cat food standards are rigorous. Sophie's grain-free cat kibble contains:

• Fresh chicken and salmon (local – Brittany has excellent poultry and fisheries): 65-70% – animal protein source
• Peas and lentils (local – France grows pulses): 10-15% – fiber and plant protein
• Poultry fat (local): 8-10% – energy source
• Vitamins and minerals: 3-5% (including taurine, which cats cannot produce)
• Taurine supplement: Added post-extrusion to prevent degradation

The extrusion process for high-meat dough requires higher moisture:

Exit moisture: 30-35% (vs 22-25% for standard kibble)

Target final moisture: 8-10% for shelf stability

Installation – Gentle Drying for Delicate Kibble

The DHG-1000 cat kibble low temperature belt dryer arrived at the Port of Le Havre – France's largest port for container traffic.

Shipping time from Qingdao to Le Havre is about 30-35 days. The machine was packed in a 40-foot container with:

• DHG-1000 dryer main unit (70kW heating + fans)
• 5-layer mesh belt conveyor system
• Control panel with PLC and temperature controllers
• Spare belts (one set – fine mesh for small kibble)
• Installation manual and electrical diagram in French

Customs clearance in Le Havre took about 3 days. Total landed cost was about 20% higher than the FOB price.

Installation took three weeks. Sophie's team prepared a concrete foundation – the DHG-1000 is about 12 meters long. They poured a 200mm reinforced slab.

The electrical hookup required 400V, 50Hz three-phase (French standard). The 70kW heater required a 160-amp breaker. Ventilation ducting was installed to exhaust moist air.

The first test run was with grain-free cat kibble at 32% moisture. The kibble was spread on the belt (layer thickness 15mm). Belt speed was set to 25 minutes per layer – total drying time 125 minutes across 5 layers. Air temperature: 75°C. Output moisture: 9%. Taurine retention: 96% (lab tested). Perfect.

Performance – Preserving Taurine, Protecting Cats

After six months of operation, Sophie documented the following results:

Before (tower dryer – 140°C):

• Drying temperature: 140°C
• Taurine retention: 72% (28% degradation)
• Kibble color: Dark, uneven
• Customer complaints: 5-6 per month about "cat not eating"
• Palatability: 70% acceptance rate

After (DHG-1000 belt dryer – 75°C):

• Drying temperature: 75°C
• Taurine retention: 96% (only 4% degradation)
• Kibble color: Light, uniform, appealing
• Customer complaints: Zero in six months
• Palatability: 95% acceptance rate (cats preferred it)

Customer Feedback – Sophie's Experience

Here's what Sophie said after six months (paraphrased from a conversation, translated from French):

Cats are finicky eaters. They can tell when food is low quality. Our tower dryer was degrading taurine and other nutrients. The kibble was dark and didn't smell right. Cats were rejecting it.

The DHG-1000 changed that. Low temperature (75°C) preserves the nutrients. Taurine retention is now 96% – up from 72%. The kibble is light and smells like fresh meat. Cats love it.

The 5-layer belt gives us 125 minutes of gentle drying at low temperature. No hot spots, no degradation. The uniform airflow preserves the kibble shape.

A few operational notes: The layer thickness needs to be thinner for cat kibble – 15mm instead of 25mm. The temperature is lower – 75°C instead of 90-100°C for dog food. The belts need weekly cleaning – cat kibble has more fat residue.

Would I recommend this machine? Yes. For any cat food manufacturer, low-temperature belt drying is essential for preserving taurine and other heat-sensitive nutrients. The DHG-1000 delivers.

Why Low Temperature for Cat Kibble

Cats have unique nutritional requirements that make low-temperature drying critical:

Taurine: Cats cannot synthesize taurine. It must come from their diet. Taurine degrades rapidly above 100°C. At 140°C (tower dryer), 28% is lost. At 75°C (belt dryer), only 4% is lost.

Essential fatty acids: Arachidonic acid and EPA are heat-sensitive. Low-temperature drying preserves these for healthy skin and coat.

Vitamins: Vitamins A, D3, E, and B-complex degrade at high temperatures. The DHG-1000 preserves 90%+.

Palatability: Cats are sensitive to smell. High-temperature drying creates off-odors. Low-temperature drying preserves the fresh meat aroma.

Sophie's lab results:

The 5-Layer Design – Gentle and Uniform at Low Temperature

The DHG-1000's 5-layer design allows extended drying at low temperature:

Layer 1: 75°C – gentle surface drying

Layer 2: 75°C – continued drying

Layer 3: 75°C – moisture migration

Layer 4: 70°C – final drying

Layer 5: 70°C – finishing to 8-10% moisture

Constant low temperature prevents nutrient degradation. Extended time (125 minutes) allows thorough drying without high heat.

Layer Thickness – Thinner for Cat Kibble

Cat kibble is smaller than dog kibble (6-8mm vs 10-12mm). Sophie uses:

Layer thickness: 15mm (vs 25mm for dog kibble)

Reason: Smaller kibble packs tighter. Thinner layer allows air to circulate.

Taurine Supplementation – Post-Drying Addition

Despite 96% retention, Sophie adds a small amount of taurine after drying as a safety margin. The taurine is sprayed onto the kibble with fat coating. This ensures that even if some degradation occurs, the final product meets AAFCO standards.

Shipping – Qingdao to Le Havre

The DHG-1000 shipped from Qingdao to Port of Le Havre, France.

Shipping time from Qingdao to Le Havre is about 30-35 days. The route goes through the South China Sea, past Singapore, across the Indian Ocean, through the Suez Canal, and across the Mediterranean to Northern Europe.

The machine was packed in a 40-foot container. Customs clearance in Le Havre took about 3 days. Total landed cost was about 20% higher than the FOB price.

The truck transport from Le Havre to Brittany was about 300km – roughly 3.5 hours.

What Sophie Learned – Lessons for Other Cat Food Manufacturers

After six months of running the DHG-1000 belt dryer machine, Sophie shared several observations:

Lesson 1: Cat kibble needs lower temperature than dog kibble. 75°C is ideal. Higher temperatures degrade taurine.

Lesson 2: Layer thickness matters. 15mm for cat kibble. Thicker layers trap moisture and cause uneven drying.

Lesson 3: Monitor taurine levels regularly. Sophie tests taurine weekly. The DHG-1000 consistently delivers 94-96% retention.

Lesson 4: Clean belts weekly. Cat kibble has higher fat content. Residue builds up faster than dog kibble.

Lesson 5: Consider post-drying taurine addition. Even with 96% retention, Sophie adds a small amount as a safety margin.

What RICHI Provided Beyond the Machine

RICHI provided several services that helped Sophie get the DHG-1000 operational:

• French documentation: The manual and electrical diagram were provided in French.
• Temperature guidance: RICHI provided recommendations for low-temperature cat kibble drying.
• Taurine retention data: RICHI provided lab data from similar installations showing taurine retention rates.
• Spare parts kit: RICHI recommended a spare parts kit based on Sophie's volume – including belts, heater elements, and sensors.
• Remote support: When Sophie had questions about temperature uniformity, a RICHI technician walked her through it via video call.

Is a Cat Kibble Low Temperature Belt Dryer Right for Your Operation?

For a cat food manufacturer producing grain-free, high-protein kibble, low-temperature belt drying is essential.

Consider the DHG-1000 if:

• Your target drying temperature is 70-80°C
• Your capacity requirement is 1-1.5 tons/hour
• You produce grain-free or high-meat cat food
• Taurine retention and palatability are priorities

Consider a larger model (DHG-2000) if:

• Your capacity requirement is 1.5-2.5 tons/hour

For Sophie's cat food plant, the DHG-1000 was the right investment. It preserved taurine (96% retention), improved palatability from 70% to 95%, and paid for itself in 10-12 months.

Final Thoughts

If you're a cat food manufacturer, don't overlook the importance of low-temperature drying. Cats are obligate carnivores with unique nutritional needs. Taurine is essential – and it's heat-sensitive. High-temperature dryers degrade taurine and other nutrients, reducing palatability and nutritional value.

The DHG-1000 cat kibble low temperature belt dryer operates at 75°C – well below the taurine degradation threshold. The 5-layer design provides 125 minutes of gentle drying. The result is nutrient-dense, highly palatable kibble that cats love.

For cat food, the math is simple: low temperature = higher taurine retention = better nutrition = happier cats = loyal customers.
