Seafood cold chain storage and processing

For commercial and industrial refrigeration projects (cold rooms, cold stores, process cooling) — not household fridges, home freezers or appliance repair. Results are planning estimates, not engineering design or safety advice; a qualified refrigeration engineer must confirm sizing before purchase.

Fish & Seafood Cold Storage Calculator

Size a fish or seafood cold store

Convert daily landings and holding days into room volume, pallet positions, refrigeration duty and an indicative CAPEX range — including ultra-low temperature tuna stores.

Required cold store

Holding 600 t of product
Floor area
463 m²
Pallet positions
667
Refrigeration duty

Seafood buyers usually need the store, the blast capacity and the ice plant quoted together — start an RFQ or review financing.

Calculation method

  1. 1. Stored mass (t) = daily intake × storage days
  2. 2. Net volume (m³) = stored kg ÷ species density (350–550 kg/m³)
  3. 3. Gross volume = net ÷ 0.45 utilisation; floor = gross ÷ (height − 1 m)
  4. 4. Pallet positions = stored kg ÷ 900 kg
  5. 5. Load (kW) = gross × W/m³ regime × (1 + (ambient − 30 °C) × 1.5%) ÷ 1000

Calculated in tonnes, m³, m² and kW. Imperial: 1 t = 2,205 lb, 1 m³ = 35.31 ft³, 1 m² = 10.76 ft², 1 kW = 3,412 BTU/h.

Worked example

Whitefish blocks, 30 t/day held 20 days at −25 °C, 7 m building, 35 °C ambient.

Inputs

  • • 600 t stored (1.32 million lb)
  • • Density 480 kg/m³ (30 lb/ft³)
  • • −25 °C regime 24 W/m³

Calculation

  • • 600,000 ÷ 480 = 1,250 m³ net
  • • 1,250 ÷ 0.45 = 2,778 m³ gross (98,100 ft³); floor ≈ 463 m² (4,980 ft²)
  • • 2,778 × 24 × 1.075 ÷ 1000 = 71.7 kW

≈ 72 kW holding load (≈ 20 TR · 245,000 BTU/h) and ≈ 667 pallet positions.

Limitations

  • • Holding load only — freezing fresh catch needs separate blast/plate freezer capacity.
  • • Densities assume cartoned or block product; bulk or glazed product varies.
  • • −60 °C tuna stores need cascade or specialised plant; treat that output as a first order of magnitude.

Direct answer

Frozen fish stores at 400–550 kg/m³ net, so 600 t of block-frozen whitefish needs roughly 1,250–1,400 m³ gross once aisles and evaporator clearance are included. Refrigeration duty runs about 20–24 W/m³ at −18 to −25 °C and 50–60 W/m³ for −60 °C tuna stores, and indicative CAPEX is USD 450–800 per m³ for standard frozen rooms and USD 1,100–1,700 per m³ for ultra-low temperature stores.

Frequently asked questions

What temperature should a fish cold store run at?

−18 °C for general frozen fish, −25 °C for long-hold export stock, and −55 to −60 °C for sashimi-grade tuna to preserve colour.

How much space does frozen fish need?

Plan 400–550 kg/m³ net for block-frozen and bulk product, or 350–400 kg/m³ for cartoned fillets and shrimp, then divide by about 0.45 utilisation for gross room volume.

Do I need an ice plant as well?

For fresh landings, yes — flake ice demand is typically 0.5–0.8 t per tonne of fish handled per day, depending on ambient temperature and haul time.

Seafood cold storage: buyer questions

How much cold storage does a fish processing plant need?
Size from peak landing or intake tonnage, hold time before dispatch and packaging format. A plant intaking 15 t/day with a 10-day frozen hold typically needs 150 t of frozen capacity plus chilled receiving, ice storage and a blast or IQF stage ahead of it.
What temperature classes does seafood need?
Fresh receiving and processing at 0 to +2 °C, frozen storage at −18 °C or colder, blast or IQF freezing to a −18 °C core, and −25 to −35 °C for tuna and premium export grades. Ice production capacity is sized separately, usually 0.5–1.0 t of ice per tonne of fresh fish handled.
Do I need ice production on site?
Landing sites and processing plants without a reliable external ice supply almost always do. Flake ice suits direct product contact and packing, block and tube ice suit transport and distribution to boats or markets.
Does ColdMatch supply the plant?
No. ColdMatch structures your requirement into a comparable RFQ and routes it to manufacturers and integrators with seafood cold chain references.
