Meat Freezing.

' "■ An'iurentibtt which is claimed to effect :conaider»ble improvements ia the present system! of freezing , meat has just been: ..-patented by Mr .Robert Niadergesaeis, of Wellington. The iur.ention s has for its object three improvements on. th ( e present mode of creating cold air. The first consists m a great saving of power caused by the diffusion of cold water into the air compressor m such a manner as to pre»' vent any rise of temperature during the ■ act of compression. The .second consists m freezing the meat at a pressure greater than the asinoaDhere, and" the third • consists 1 m utilising toe heat, of the. meat, :- tmf heat tfhat finds its way 'ttironj:h con-duction-in the' fr&bzii/g chafmbar, and! the . heat of ' any available^ water ■or other , material that is warmer than the return* ing air from the chamber*? TJiepinrpntor claims (1) ; the compression ot. air undpr.a constant or even at a, decreasing' tempera" turft J (2) the application of freezing under a pressure higher than the atmosphere i add (3) the rise of a cylinder m Which' the ; retaining expanded air is utilised. ;Mr , N iedergesaess : has given ithe .subject a • ; - good deal of attention, and is convinced ; that if his infection were substituted for; the system m use at present a saving of '■' about 90 pec cent: m coal alone would be '"♦fleeted.'
