English demand This historical importance of the
Dunedin is due to this meat shipment, which proved refrigerated meat could be exported long distances, so establishing the
New Zealand meat export industry, and transforming agriculture in New Zealand and Australia. In the
United Kingdom (UK), the rapidly expanding population had outrun the supply of local meat, resulting in rapid increases in prices. However, the shipment of livestock from New Zealand to England was prohibitively expensive. New Zealand did export some canned meat, but the industry was in its infancy, and while the product was popular in the Pacific islands, it was less so in England.
Early attempts The first attempt to ship refrigerated meat from
Australasia was made when the
Northam sailed from
Australia to England in 1876; however the
refrigeration machinery broke down en route and so the cargo was lost. Later that year chilled beef was sent from the
United States to England (a shorter journey, at cooler, higher
latitudes) and, although spoilage was high, this voyage provided some encouragement to Australian and New Zealand promoters of refrigeration. During 1877 the steamers
Le Frigorifique and
Paraguay carried frozen
mutton from
Argentina to
France, proving the concept, if not the economic case, for longer-distance refrigerated shipping. In 1879 the
Strathleven, equipped with compression refrigeration, sailed from
Sydney with of frozen beef and mutton as a small part of her cargo, and this meat arrived in good condition. As a result of this success a Director of the New Zealand and Australian Land Company (NZALC),
William Soltau Davidson, sent an employee,
Thomas Brydone, from New Zealand to the UK to investigate compression refrigeration units.
The Dunedin refit In 1880 Davidson convinced the company to invest in refrigeration. Teaming up with James Galbraith of the Albion shipping company, they approached John Bell and Sons and
Joseph James Coleman, who had been involved in American chilled beef shipments. As a result of negotiations, Albion agreed to refit the
Dunedin with a Bell-Coleman
compression refrigeration machine, cooling the entire hold. Using 3 tons of coal a day, this steam-powered machine could chill the hold to below surrounding air temperature, freezing the cargo in the temperate climate of southern New Zealand, and then maintaining it beneath zero through the tropics. The
Dunedin was refitted in May 1881, the most visible sign being a funnel for the refrigeration plant between her fore and main masts – sometimes leading her to be mistaken for a steamship. The refitted
Dunedin arrived in
Dunedin's
Port Chalmers at the end of November 1881. ==1882 voyage==
