Ice Machine Projects in Vietnam

A block ice plant concept for Vietnam.

Example proposal — not a completed Nineyan project. This scenario illustrates how a block ice production inquiry for a fishing supply business could be developed. No customer, installation site, delivery date or operating results are claimed.

This concept draws on publicly reported industry examples. Robin Machinery describes block ice equipment intended for Vietnam's fishing market. That is a third-party reported shipment, not Nineyan's project or evidence about the equipment pictured here.

30 tonnes of ice per day for harbour supply planning.

The owner identifies the pictured equipment as a 30-ton block ice machine. The calculations below use a nominal output of 30 metric tonnes per 24 hours, equal to 30,000 kg of ice. They are planning examples, not measured production results from a Vietnam installation. Block weight, freezing cycle, electrical demand, dimensions and performance test conditions for this pictured machine have not yet been confirmed.

How many blocks can it produce?

Daily blocks = daily ice mass in kilograms ÷ weight of one block. A smaller block gives a larger block count, but does not increase the total daily ice mass. The weights below are illustrative alternatives; they do not establish that this machine supports each mold size.

For example, if the confirmed mold produces 50 kg blocks and the plant achieves 30,000 kg in 24 hours, the arithmetic gives 600 blocks per day. This does not mean 25 finished blocks leave the machine every hour: harvesting occurs in batches. The average mass rate is 1,250 kg/hour over 24 hours, but a freezing-cycle schedule and mold count are needed to establish actual harvest times. Do not extrapolate a 24-hour rating to a shorter shift without checking the operating cycle.

Plan for usable ice, not just the nameplate capacity.

Output and dispatchable stock must be checked against the manufacturer's operating conditions and the site's water supply, electrical supply, ambient conditions and harvesting arrangements. Storage and handling can also reduce the mass available for sale. As a calculation example only, allowing a hypothetical 10% reduction from 30,000 kg leaves 27,000 kg, equivalent to 540 blocks at 50 kg. The 10% figure is not a measured loss rate or a prediction for this machine.

What problems could it help a fishing harbour address?

A worked dispatch example

Assume, solely for planning, that 30,000 kg is available and one vessel orders 2,000 kg. Dividing gives 15 such orders before any allocation to other customers, reserves or losses. At 50 kg per block, that is 40 blocks per order. This is a dispatch calculation, not a claim that one machine can serve 15 vessels of any size or trip duration. An operator would first confirm each vessel's intended trip, expected catch, insulation and existing ice stock.

Use block ice correctly around fish

FAO explains that ice needs good contact with fish: large blocks should be crushed into suitable small pieces before direct application. Clean ice should surround the fish, and gentle handling helps avoid physical damage. The block format offers a bulk storage option, while crushing provides contact during use. Prompt icing and protection from heat matter; ice does not reverse deterioration that has already occurred. Source: FAO, use of ice on fishing vessels.

Why 30 tonnes of ice does not equal 30 tonnes of fish

The ice requirement has two parts: cooling the catch initially and replacing heat entering during storage and travel. Required quantities vary with starting temperature, fish handling, insulation and time. Consequently, do not assign a fixed fish throughput or a guaranteed shelf life to this machine from its daily ice rating. A project-specific cooling and logistics assessment is needed.

Information needed before a harbour quotation

Prepare a demand schedule covering vessel departures, landed catch and seasonal peaks. Confirm the available land and loading route, water source, electricity, drainage and room for future expansion. Review access to local operating skills and spare parts. FAO treats these as important considerations in planning fish landing and marketing facilities. Source: FAO, elements for planning.

• Confirm the required block weight and the machine's actual mold configuration.
• Request verified production conditions, cycle duration, molds per batch and harvesting procedure.
• Confirm electrical input, power consumption, water requirements, refrigerant and site layout with the technical team.
• Plan storage, lifting, crushing, weighing and dispatch equipment separately; their inclusion is subject to quotation.
• Agree the Vietnam partner's installation and commissioning scope, charges and schedule before work starts.

The practical value is a planned ice supply for an identified harbour operation. Savings, reduced product loss, customer coverage and return on investment should be assessed from the operator's own data; no numerical performance or financial outcome is promised here.
