Why Are Paddle Dryers the Ultimate Solution for Food Industry Drying? Discover JexDry’s Expertise

In the competitive food industry, preserving flavor, color, and nutritional integrity during drying is critical. Traditional methods like spray drying often fail to protect heat-sensitive compounds, leading to degraded product quality.

How can manufacturers achieve energy-efficient drying while complying with stringent food safety standards?

JexDry Industrial Drying Solutions leverages vacuum paddle dryer technology to deliver GMP-compliant, low-temperature drying tailored for spices, probiotics, plant-based proteins, and more.

JexDry’s paddle dryers excel in processing sticky pastes, high-moisture slurries, and solvent-laden extracts. With ±1°C temperature control and 99.8% solvent recovery, our systems outperform rotary and spray dryers in both quality retention and operational efficiency. Explore how a South Korean sauce producer reduced drying costs by 40% while maintaining 98.5% glutamate retention in our case study below.

From powdered seasonings to freeze-dried fruits, paddle dryers are transforming food production. Below, we break down their technical advantages, real-world success stories, and why JexDry outperforms competitors in precision and reliability.

1.How Do Paddle Dryers Maintain Food Quality and Safety?

Heat-sensitive ingredients like probiotics, enzymes, and natural pigments require precise temperature control. JexDry’s paddle dryers use indirect heating via hollow paddles to eliminate hot spots, ensuring uniform drying at 30–80°C—ideal for preserving bioactive compounds. For example, drying paprika at 65°C (vs. 90°C in rotary dryers) retains its vibrant color and capsaicin content.

4.Paddle Dryer vs. Spray Dryer – Which Is Better for Your Application?

While spray dryers dominate liquid drying, JexDry’s paddle dryers excel in:

• Heat-sensitive materials (e.g., lactic acid bacteria cultures).

• High-viscosity slurries (e.g., fruit purees).

• Solvent recovery (critical for ethanol-based extracts).
