Efficient freeze tunnel preparation is essential for achieving optimal product quality, minimizing ice buildup, and maintaining consistent throughput in food processing. A key step in this process is fluid removal, and that’s where systems like WaterVac® from REYCO Systems play a vital role. By eliminating excess surface moisture before products enter the freezer, these systems help facilities maintain efficiency, reduce sanitation issues, and improve overall product integrity.
Why Fluid Removal Matters Before Freezing
When food products are transferred directly from rinsing or blanching processes into a freeze tunnel, excess moisture can cause major challenges. Not only does water on the surface of products slow the freezing process, but it also leads to ice accumulation within the tunnel, increasing maintenance needs and energy consumption.
Fluid removal technology addresses these challenges by removing surface water and moisture prior to freezing. This small but critical step improves the overall performance of the freeze tunnel while preserving the texture and appearance of the product.
WaterVac®: A Smarter Way to Prepare for Freezing
REYCO’s WaterVac® system is specifically engineered to support freeze tunnel preparation by removing excess surface water through gentle vacuum suction. Designed for integration with conveyor systems, WaterVac provides non-contact moisture removal that’s both fast and effective, ideal for products like vegetables, fruits, and IQF items.
Key Features:
- Gentle suction: Protects delicate products during the drying phase
- Inline design: Fits seamlessly into existing conveyor systems
- High-efficiency performance: Consistently removes moisture without the need for heat or compressed air
- Reduced ice formation: Prevents buildup inside freeze tunnels and minimizes downtime
Benefits of Fluid Removal in Freeze Tunnel Preparation
Incorporating fluid removal systems like WaterVac before freezing leads to both immediate and long-term benefits for processors:
1. Faster and More Efficient Freezing
Removing moisture accelerates the freezing process by eliminating the thermal mass of surface water. This allows the freezer to operate more efficiently and reduces energy consumption.
2. Improved Product Quality
Moisture left on the product surface can lead to clumping or unwanted texture changes. One of the most critical benefits of pre-freeze moisture removal is minimizing frost and ice crystal formation inside retail packaging.
By extracting surface water before freezing, WaterVac helps ensure that consumers don’t open a bag of frozen vegetables—or any frozen product—only to find excess ice buildup at the bottom.
3. Cleaner Freeze Tunnel Environment
Excess water causes frost and ice buildup inside the tunnel, increasing the need for defrost cycles and sanitation efforts. Moisture removal keeps freeze tunnels cleaner and reduces the risk of microbial growth.
4. Minimized Waste and Downtime
By reducing clumping, sticking, and freeze-tunnel contamination, processors experience less waste, fewer mechanical issues, and fewer production interruptions.
Supporting Sustainability and Sanitation
Effective fluid removal technology also supports broader sustainability and food safety goals. By eliminating the need for additional drying steps that use heat or compressed air, systems like WaterVac reduce energy usage. Additionally, maintaining a drier freeze tunnel environment decreases water usage in cleaning and sanitation processes.
This not only aligns with environmental responsibility but also helps facilities meet regulatory compliance and hygiene standards more easily.
Designed for Versatility and Integration
Whether you’re working with diced onions, sliced fruits, leafy greens, or IQF-ready vegetables, REYCO’s WaterVac® system can be configured to match your product type and line speed. The system’s modular design allows it to integrate seamlessly into new or existing processing lines, making it a cost-effective upgrade for processors focused on quality and efficiency.

FAQs
Why is fluid removal important before entering the freeze tunnel
Excess surface moisture slows down freezing times, increases energy usage, and contributes to ice buildup inside the tunnel. Removing moisture ensures faster, cleaner, and more efficient freeze tunnel operation.
What types of food products benefit from fluid removal systems like WaterVac®?
Products such as IQF vegetables, fruits, leafy greens, diced onions, and other freshly rinsed or blanched items benefit greatly from moisture removal before freezing.
How does WaterVac® work?
WaterVac® uses a gentle vacuum system to remove surface water from products as they move along the conveyor. It does so without damaging delicate items or using heat or compressed air.
Will adding a fluid removal system increase line downtime or require major changes to my line?
Not at all. WaterVac® is designed for inline integration and minimal disruption. It can be added to most conveyor systems without major modifications and improves uptime by reducing freeze tunnel maintenance.
Can fluid removal systems help reduce sanitation and maintenance costs?
Yes. By minimizing moisture entering the freeze tunnel, these systems reduce ice buildup, lower the need for defrost cycles, and help maintain a cleaner, more hygienic production environment.
