STELA Food & Pet Food Belt Dryers: Precision Drying by Design

STELA food and pet food belt dryers utilize a controlled, low-temperature drying process specifically engineered to safeguard sensitive products while ensuring stable and repeatable results. Through the use of continuous belt transport and modular system design, these dryers allow for precise control over residence time, enabling operators to tailor drying conditions to the unique characteristics and moisture targets of each product. Systems are available with a range of heat sources, including steam, thermal oil, heat pump, excess/waste heat recovery, and indirect gas-fired configurations, to suit facility infrastructure and energy requirements. This sophisticated approach balances gentle handling with high-performance efficiency to maintain the nutritional and structural integrity of the feed.

Continuous Belt Dryer Systems

Every system is custom-engineered to align with specific product behaviors, throughput requirements, and unique operational constraints. By utilizing stainless steel construction and hygienic layouts, these dryers support strict food-grade standards while maintaining the rugged durability needed for long-term reliability in industrial environments. This focus on gentle product handling and robust design ensures that even the most sensitive materials are processed efficiently without compromising quality.

Typical Applications

Product Offering

Layer dryer for products requiring longer retention time
The BTF-L is a high-capacity layer dryer that stacks multiple belts vertically to maximize drying surface area within a compact, enclosed footprint. This design is optimized for continuous food and pet food production, providing the extended residence time needed for gradual warming and uniform moisture removal.

KEy Features

  • Space Efficiency: Vertical stacking delivers a large drying surface in a minimal installation area.

  • Precision Control: Adjustable belt speeds allow for exact residence time management.

  • Airflow Zoning: Independently configurable TopDown and BottomUp airflow per zone enables precise climate control tailored to product behavior throughout the drying cycle.

  • Hygienic Design: Full stainless steel construction tailored for sanitary processing environments.

  • Process Stability: Enclosed housing ensures consistent thermal conditions for high-throughput volumes.

Core Applications

  • Process Focus: Products requiring moderate moisture removal and uniform drying at high volumes.
Optimized for higher throughput with shorter retention times
The BTF-S is a high-efficiency stage dryer designed for the food and pet food sectors. Unlike vertical models, it utilizes multiple belts arranged sequentially to move product through successive drying stages. This configuration is optimized for shorter retention times and high-throughput, low-temperature drying.

KEy Features

  • Sequential Processing: Multiple stages arranged in-line for gradual, controlled moisture reduction.

  • Airflow Zoning: Independently configurable TopDown and BottomUp airflow per zone allows each drying stage to be fine-tuned for optimal moisture removal.

  • Gentle Treatment: Engineered for low-temperature drying to preserve product quality and integrity.

  • Precision Control: Adjustable belt speeds across stages allow for exact residence time management.

  • Hygienic Design: Full stainless steel construction meeting strict food-grade sanitary standards.

Core Applications

  • Process Focus: Products with higher moisture content requiring staged dehydration and uniform distribution at high volumes.
Core Benefits for

The Food and Pet Food Industry

STELA’s low-temperature drying technology supports food and pet food producers where product quality, consistency, and process reliability are critical. Gentle drying and precise control help protect sensitive products while supporting stable, repeatable operation.

Product Quality and Consistency

Low-temperature drying helps preserve taste, texture, color, and nutritional properties. Controlled drying conditions and residence time deliver consistent moisture levels and help reduce product losses.

Hygienic & Reliable Operation

STELA systems are designed for food-grade applications, using stainless steel construction that support effective cleaning. Gentle product handling contributes to reliable operation and long equipment life.

Process Flexibility and Control

Adjustable drying zones, including configurable TopDown and BottomUp airflow per zone, and process control allow producers to adapt to different products, sizes, and moisture targets.  

Scalable & Predictable Production

STELA belt dryer systems support stable, repeatable operation as production volumes increase. Modular system design allows capacity to scale confidently while maintaining consistent product quality.
