Why Are Paddle Dryers the Ultimate Solution for Food Industry Drying? Discover JexDry’s Expertise
3/31/20254 min read


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.
