Cold-chain project profile

Blast Freezing Facility Procurement

How a blast freezing facility is scoped and tendered: freezing method, plant capacity, envelope, handling and controls packages, tender sequence, risks and financing routes.

Blast freezing is specified by freezing curve, not by room size. Product type, entry temperature, core temperature target and batch or continuous throughput decide the freezing method, the plant capacity and the airflow design — and those decide almost everything else in the tender. This profile describes how a blast freezing scope is split into tenderable packages and what has to be defined before an RFQ is issued.

This is an anonymized scope profile describing how projects of this type are structured and procured — not a client case study. Figures are scope bands, not quotations.

Freezing methods

Blast cells · Tunnel (batch/continuous) · Spiral · Plate · IQF fluidised bed

Typical duty

Entry +4 to +25 °C down to a −18 °C core, within a defined freezing window

Lead-time driver

Refrigeration plant, spiral or IQF line fabrication

Buyer cost

How the scope splits into tenderable packages

Freezing equipment

Blast cells, tunnel, spiral or IQF line sized to the freezing curve and hourly product throughput.

Refrigeration plant

Low-temperature compressor selection (ammonia, CO₂ cascade, HFC/HFO), condensers, evaporators, hot-gas or electric defrost strategy and redundancy level.

Insulated envelope

Freezer-grade panels, underfloor heating against frost heave, vapour barrier, doors and air locks.

Product handling

Trolleys, racks, conveyors or loading systems, and the interface into frozen storage or dispatch.

Controls and validation

PLC/SCADA, core-temperature probes, batch records for food-safety audit, alarms and remote monitoring.

Installation and commissioning

Site interface, pull-down and freezing-curve verification with real product, operator training and spares list.

Procurement sequence

1. Define the freezing curve
Product, packaging format, entry temperature, target core temperature and the permitted freezing time — this is the specification everything else derives from.
2. Fix hourly throughput and batch pattern
Kilograms per hour at peak season, not annual tonnage, determines plant capacity and whether batch cells or a continuous line is correct.
3. Choose the method before the supplier
Blast cells, tunnel, spiral and IQF suit different products and labour models; deciding late makes bids non-comparable.
4. Split into packages
Freezing equipment, refrigeration plant, envelope, handling and controls are tendered separately with a defined interface matrix.
5. Compare on energy per tonne frozen
Normalise bids for kWh per tonne at stated design conditions, defrost losses, dehydration weight loss and warranty terms.
6. Route to financing
Where eligible, the equipment package is matched to export credit, leasing or development-bank cold-chain routes before signature.

Risks and controls

Risk	Control
Freezing time missed at peak season	Specify the design product and peak hourly load in the RFQ, and require a guaranteed freezing curve.
Product dehydration and weight loss	Require stated weight-loss performance at the design airflow and packaging format.
Frost heave under the freezer floor	Include underfloor heating or ventilated slab in the envelope scope, not as a site-works assumption.
Defrost strategy eroding capacity	Require defrost frequency and duration in the capacity calculation, not just nominal plant output.

Financing routes commonly assessed

Export credit agency cover where freezing equipment originates from an ECA-supported country
Equipment leasing for refrigeration plant and freezing lines
Development-bank lines for cold-chain and post-harvest loss reduction
Vendor and trade finance on the supply contract

Eligibility depends on jurisdiction, equipment origin and sponsor profile. Financing Center

Illustrative documentation

Example project report: from buyer to investment decision

These are sample report excerpts for a project of this type, not a real client file, supplier offer, financing commitment or CAPEX approval. Names, prices, dates and decision outcomes must come from the buyer and be verified before use.

Global B2B Group works on commercial and industrial projects from USD 250,000 upward.

01 / Corporate and sponsor report

Example entry: Applicant legal entity: to be provided by the buyer. Jurisdiction, registration number, beneficial ownership, authorized signatories and corporate group structure: pending documentation. ColdMatch Group is the specialist routing destination for this scope, not the buyer or its legal sponsor.

The file should attach registration and ownership documents, evidence of authority to request proposals, sponsor accounts where available, and a named decision owner. The reviewer records what has been received, what remains open and whether disclosure to potential suppliers is authorized. No supplier outreach follows until human review.

02 / Project description and technical scope

Example entry: Blast Freezing Facility Procurement. The buyer states the site, product, required output and operating assumptions; these inputs remain open until confirmed. The first tender schedule separates freezing equipment from refrigeration plant, rather than asking suppliers for one unexplained total.

Scope excerpt — Freezing equipment: Blast cells, tunnel, spiral or IQF line sized to the freezing curve and hourly product throughput. Record the technical specification, battery limits, utilities and acceptance test for this package; assign responsibility for its interface with the next package.

The annex should identify site constraints, local permits, installation and commissioning responsibilities, warranty boundaries and evaluation criteria. Missing capacity, site or utility information is flagged for the buyer rather than filled with assumptions.

03 / Financing-readiness report

Example entry: Funding requirement: not stated; buyer equity contribution: not stated; debt request: not stated. The cost schedule distinguishes equipment, freight and duties, civil works, installation, commissioning, contingency and initial working capital. Supplier quotations and a cash-flow model are required before calculating a funding gap or debt-service capacity.

Routes for preliminary screening include export credit agency cover where freezing equipment originates from an eca-supported country and equipment leasing for refrigeration plant and freezing lines. These are options to assess, not available facilities. A provider will independently test sponsor strength, equipment origin, permits, contracts and repayment assumptions. Global B2B Group is not a lender, insurer or financing approver.

Financing documentation guide

04 / CAPEX approval memorandum

Example recommendation: Hold the investment decision pending a confirmed budget, like-for-like supplier bids and a documented funding plan. Show the base case, contingency, total installed cost, operating assumptions and an alternative to proceeding. No board decision or approved amount is implied by this example.

Risk-register excerpt: Freezing time missed at peak season. Proposed control: Specify the design product and peak hourly load in the RFQ, and require a guaranteed freezing curve. Assign an owner and evidence deadline before the approval meeting.

Approval gates: technical scope signed off by the buyer; commercial comparison and exclusions reviewed; funding source confirmed by the relevant decision-maker; permits and delivery dependencies assessed; board or investment committee resolution recorded. Only the buyer can approve its CAPEX.

CAPEX approval process

Questions buyers ask

What decides blast freezing capacity?

The freezing curve and peak hourly throughput. Product type, packaging, entry temperature, the −18 °C core target and the permitted freezing time set the required refrigeration duty and airflow — floor area follows from that, not the other way round.

Blast cells, tunnel or IQF — how is the method chosen?

By product format and labour model. Cartoned and palletised product usually suits batch blast cells or a tunnel; loose, individually frozen pieces need a spiral or fluidised-bed IQF line with continuous handling.

How should blast freezing bids be compared?

On energy per tonne frozen at design conditions, guaranteed freezing time, product weight loss, defrost impact on effective capacity, service coverage in-country, and warranty and payment terms — not on headline equipment price.
