IQF Freezing System for Fruit, Vegetables and Seafood

IQF Freezing System for Fruit, Vegetables and Seafood

A configurable individual quick-freezing line using fluidized-bed, belt or application-specific freezing to pass the maximum-crystallization zone rapidly and deliver free-flowing product at a stabilized thermal-centre temperature of -18 °C or colder.

AgriTech.tr prepares this entry as a supplier-neutral technical sourcing scope so buyers can define a comparable request before suitable suppliers are researched and confirmed during sourcing. It does not reproduce a single vendor catalogue. Depending on the project, the potential scope may include local equipment and services or imported specialist components where technically necessary; the actual supplier and origin are confirmed during the quotation process.

Technical sourcing scope

The values below are not guaranteed single-model performance. They are typical, configurable procurement envelopes used to place competing quotations on the same engineering basis. Capacity, recipe, climate, water analysis, feedstock properties, target quality, utilities, and destination-country requirements are frozen in the final project schedule.

Process and integration sequence

1. Define product size, inlet temperature, moisture, coating and hourly load.
2. Prepare, dewater and distribute pieces in a controlled single layer.
3. Freeze rapidly through the maximum-crystallization zone.
4. Verify thermal-centre temperature, separation and yield before packing.
5. Transfer immediately to packaging and compliant frozen storage.

The line or system boundary is documented through a responsibility matrix covering reception and infeed, process equipment, automation, safety, product discharge, utility interfaces, and data records. For brownfield integration, electrical single lines, piping and instrumentation, floor/loading data, drainage, ventilation, water quality, compressed air, steam, refrigeration, and network interfaces are reviewed before order.

Suitable applications

• Berries and diced fruit
• Peas, sweet corn and vegetables
• Shrimp and selected seafood
• Frozen-food processors and exporters

Engineering, compliance, and acceptance

• Quotations are compared against the same feed or product specification, inlet condition, shift pattern, net capacity, and target output quality.
• Food-contact materials, machine safety, electrical panels, pressure equipment, refrigerants, emissions, occupational safety, and hygienic design are specified for the destination and the actual process risk.
• Factory and site acceptance tests define the measurement method, sample size, tolerances, run duration, rejection criteria, and correction period in writing.
• The procurement dossier requests a revision-controlled technical schedule, equipment and motor lists, material specifications, utility consumption, critical spares, preventive maintenance, manuals, and operator training.
• Capacity, yield, energy, water, product-loss, quality, or biological-performance statements are not treated as guarantees without the actual design inputs and an agreed acceptance test.

How to compare quotations

• Verified throughput for product and piece size
• Core-temperature pull-down curve
• Cluster and block percentage
• Yield loss and dehydration
• Refrigeration energy per kilogram
• Defrost and cleaning downtime

Buyers should request at least three comparable quotations, references for similar installations in Türkiye, CE/conformity documentation, warranty boundaries, critical-spares lead times, and after-sales response commitments. This makes lifecycle cost, operability, and local service capacity visible alongside the purchase price.

Technical references

• Codex quick-frozen food standards
• EU quick-frozen food requirements
• FAO freezing of fruits and vegetables

The references support process principles and design boundaries; they do not certify a particular supplier’s performance. Final acceptance is based on the selected supplier’s written offer, project engineering, site review, and FAT/SAT protocol.
