Spiral, tunnel, fluidised bed and plate freezers for fish and shrimp.
Request matched quotesShort answer
How much does a iqf & freezing systems cost?
- Freezing energy:
- 70–160 kWh per tonne product depending on system and product form
- Dwell time:
- 8–25 min shrimp, 20–60 min fillets, 2–6 h plate blocks
- Dehydration loss:
- 0.5–2% without glazing control
- Defrost downtime:
- Plan 1–2 h per shift for continuous IQF lines
Throughput and indicative CAPEX bands
Indicative equipment supply only (EXW/FOB). Building, civil works, duties and local installation are additional.
| Scale | Throughput | Indicative CAPEX | Typical scope |
|---|---|---|---|
| Blast / batch | 1–5 t/day | USD 30k–120k | Blast rooms and trolley freezers for mixed low-volume product. |
| Tunnel IQF | 500–1,500 kg/h | USD 80k–250k | Straight belt or fluidised bed, best for shrimp and small pieces. |
| Spiral IQF | 1,000–4,000 kg/h | USD 300k–1.2M | Compact footprint, long dwell time for fillets and coated products. |
| Plate freezing | Bulk blocks | USD 60k–400k | Highest energy efficiency per tonne for commodity block export. |
What a complete scope must cover
Freezer unit
Belt or plate system sized on product thickness, entry temperature and required core temperature.
Refrigeration plant
Ammonia, CO₂ or HFC packages. Often 40–60% of total freezing CAPEX — never omit it from the tender.
Glazing & hardening
Glazing tunnel and hardening room to hold declared net weight and prevent freezer burn.
Controls & validation
Core temperature logging for HACCP, defrost strategy, alarm and remote monitoring.
Cold store link
Buffer store and pallet handling sized against production and shipment intervals.
Machine, line, turnkey plant or EPC scope?
Compare offers at the same responsibility level. A low machine price is not comparable with a line that includes controls, utilities, installation and performance acceptance.
| Scope | Typically includes | Buyer retains | Use when |
|---|---|---|---|
| Single machine | One defined operation and controls | Interfaces, utilities, installation and line balance | The factory and upstream/downstream process already exist |
| Complete line | Connected process equipment, controls and throughput duty | Building, major utilities, cold store and permits unless stated | One product flow needs a measurable output guarantee |
| Turnkey plant | Line, utilities, installation, commissioning and training as contracted | Land, approvals, raw material and items expressly excluded | The buyer wants fewer package interfaces |
| EPC scope | Engineering, procurement and construction coordination under an agreed contract | Owner decisions, financing, permits and operational inputs | Civil works and multiple technical packages must be integrated |
Selection criteria
- •Capacity stated at your entry temperature and product thickness, not at ideal lab conditions
- •Refrigerant choice against local regulation, service skills and F-gas phase-down
- •Belt hygiene and CIP access — seafood belts foul fast
- •Energy per tonne guarantee, backed by a measured acceptance test
- •Redundancy: one compressor down should not stop the harvest
Costly mistakes
- •Quoting freezer capacity without the refrigeration plant and then discovering a 50% budget gap
- •Sizing on average day rather than peak harvest day
- •Ignoring defrost time in the daily throughput calculation
- •Selecting a refrigerant with no qualified local service technicians
Put this in your RFQ
- •Specify entry and required core temperature, product thickness and hourly rate
- •Ask for kWh per tonne and require verification at commissioning
- •Include refrigeration plant, glazing, controls and cold store interface in one scope
- •Request a defrost and cleaning schedule with its impact on effective daily capacity

Before you request quotes
Equipment scope
What equipment does a commercial aquaculture project actually need?
A grow-out project typically needs holding infrastructure (tanks, ponds or cages), water movement (pumps, piping, valves), aeration or oxygenation, water treatment appropriate to the system, feeding equipment, grading and handling gear, monitoring and alarms, and backup power. RAS adds mechanical filtration, biofiltration, degassing, disinfection and tighter process control. Hatchery and processing scopes are specified separately.
Which equipment should be specified before requesting quotes?
Specify the items whose sizing changes everything downstream: design biomass and stocking density, water exchange or recirculation rate, oxygen demand at peak temperature, and installed pumping head. With those four fixed, suppliers can quote aeration, filtration, pumps and power on the same basis. FishMatch calculators produce these figures and attach them to the RFQ.
Can equipment be sourced in stages?
Yes, and phased procurement is common. The usual sequence is water supply and holding infrastructure, then aeration and treatment, then automation and monitoring, then processing and cold chain. Staging works when interfaces and capacity headroom are defined at the start; otherwise later phases force replacement rather than addition.
