THE MATURA'S REFRIGERATOR.

In connection with the arrival of the ship Malura at Lyttelton, fitted up for the meat trade between New Zealand and the United Kingdom, the following has been published in regard to refrigerators: The Bell-Cdlemah refrigerator was the first tried by ocean-going vessels in the. meat-carrying trade, but it would seem that the patent to be seen on board the Mataura, and called Haslam’s Dry Air Refrigerator, is superior in many respects to. the BeUrCpleman freezing process. The . Orient, Steam Navigation, Company, the Gunard Shipping Company, the* Brisbane Meat Preserving Company, the ' Dunedin Meat Oorapahy, and several other companies have adopted , this, patent in preference. The London Times, O ct. sth, of last year, says : Three vessels of the Orient Line are fitted with reCuzco |WUb thg, Bejlr Coleman machine,-'and the Garonne and the Orient' With 'the ' Haslam ’ machine. The difference in 'the machines is that in the former the process of, freezing is by means of wet air, .and in the. latter by dry ’air only. Mr Alfred S’.TLisTam", of . the Haslam Foundry and ; Engineering Company, Derby, the patentee, placed the machih^'in the Orient-pre-vions to, t her oufward , passage. Mr Haslam came to Plymouth; for the express purpose of ascertaining the re 7 suit ...of...the experiment. In company with Mr s Scott, the chief engineer of the Orient, Mr Haslam inspected, the .rg-. frigerating machinery: and: the chambers 'in which the meat was located. The machine, which had been kept going twenty out. of the twenty-four hours during the whole passage, excepting in ipassing,;the Baez,.Canal, continually run, ;adjoins the /engines of :the vessel. It takes ,up very little, space. The atmosphere with the engine at work;was' "decidedly .close.- • Lhq IheC machine and refrigerator water and air may enter at 90 degrees. Further, the air being compressed, to about; 401b per square inch and heated to'about 280 degrees, is then passed through the refrigerator ,'and expanded, leaving the machine at a temperature ranging from 40 tb .60 degrees belowi zero. Regularly the machine discharges.a volume of air jat the rale hour # 40 degrees below zero, i When 'refrigerating with water J at 90 ‘ degrees. Fab., pure dry ..aiiiJ.is ,deliy,ei;e.d.... into, the. Chamber .40 to 60 f degrees below zero. A similar degree’‘of cold is to be obtained with watep at 50 degrees Fahj It is a j most important point to know that : , heat of the. tropics does! not interfere” with the freezing ! ; ...ft ... ■ ;;;-j H • rfC process;; ' ... . ~
