MAKING OF BUTTER

PROCESSES IN GERMANY NEW ZEALANDEIiS' VISIT By Telegraph—Press Association —Copyright (X.Z.P.A. Special Corespondent) (Herd. 0.30 p.m.) LONDON, Oct, '2<> Butter-making without churning is one of the latest developments in the dairy industry. New methods, known as continuous processing, have been perfected with machinery which saves labour, occupies less factory space and reduces overall costs. Two distinct methods were investigated in Germany during a recent visit by Mr Frank Taylor, New Zealand dairy inspector in London, Dr I. E. Coop, New Zealand scientific liaison officer, and Dr J. A. B. Smith, of the Hannah Dairy Research Institute at Ayr, Scotland. Germans Claim Success At the -Kiel Dairy Research Institute in the famous Sehleswig-Holstein district, and at the Weihenstephan research station near Munich, they learned that the Germans wore using processes known as Alfa and Fritz with considerable success. In the Alfa process, developed at Kiel, the milk is first separated, and the constituency of the resultant cream is 78 per cent butter-fat, 20 per cent water and 2 per cent solids not fats. This cream is boated and subjected to ! sudden chilling, its temperature falling by 50 degrees Centigrade. No Buttermilk The effect- is to transform it from an emulsion of fat in water to water ill fat, i or butter, which is nnsalted. 'there is , no residue or buttermilk, the cream I entering at one point of the machine ! and the butter being discharged from j the other. There is no contact with air 1 or water during this process. _ _ The Fritz method, which originated nt the Weihenstephan research station, differs in pringiple. Cream with 40 per ! cent to 50 per cent butter-fat contentis subjected to rapid agitation by passing it through a cylinder in winch blades are rotating at 3000 revolutions a minute. In one and a-half seconds, the cream is separated into butter and buttermilk, the butter being carried automatically into a _ mixing chamber where the buttermilk is run off and the ' butter is finally discharged into packing machines. Two Tons an Hour Fritz machines capable of producing two tons of butter an hour are operating in Germany. It is claimed by^the Germans, who have installed 60 I'ritz and 12 Alfa plants in their dairying districts, that these new processes give an improved tvpe of butter. • Both Mr"Taylor and Dr Coop are reserved in their opinion whether . improvement would apply to New Zealand if machinery were introduced there. They feel that several trials ■would be necessary before the German claim could be substantiated. 1 It is certain, however, that this type i of butter-making without churns is attracting considerable attention in the | dairying world. The Danes are watching developments with closo attention, and experiments in Sweden and Switzerland , may require New Zealand's interest. Report to Government

Dr Coop is shortly returning to New ' Zealand. With Mr Taylor and D.r Smith I he is producing a report upon the German methods which will shortly be m the hands of the New Zealand Government. Another development which interested the visitors is a claim that ultraviolet rays can be used for the pasteuris- . ation of milk in the cold. The New Zealanders and Dr Smith, however, consider that further tests are required before the Germans' high opinion of this method can be confirmed. , Hitherto, successful ultra-violet ray pasteurisation has beep complicated by the opacity.of the milk, which withstood penetration by the rays. Ihe German method is to pass the milk through long lengths of quartz tubing. Ultra-violet ray tubes are interspersed •with this tubing in such a way to enstire that the milk is thoroughly "penetrated" from all angles. The Germans claim that in addition to successful pasteurisation, vitamin D is added dur- <• ing the process, thereby increasing the food value for children.

COMMERCE CONFERENCE NEW ZEALAND DELEGATES EMPIRE PREFERENCE BACKED LONDON, Oct. 25 Speaking at the recent conference of the Federation of Chambers of Commerce of the British Empire, Mr S. Jacobs, representative of the Associated Chambers of Commerce of New Zea--1 land, said he considered the greatest I value of such conferences was personal contacts. He remarked the defence of i [Australia and New Zealand was not a local but an international matter. Defence in itself, he added, should not be made the first priority in economic matters. He was of the opinion the - interlocking interests of Britain's and New Zealand's agriculture were not competitive, but reciprocal. "The whole atmosphere of the conference," he concluded, "showed the desire of all overseas delegates to link up again in trade with Britain as soon as possible." New Zealand delegates at the conference besides Mr Jacobs were Mr W. G. V. Fernie, from Canterbury, and Mr J. F. Johnston, of Auckland, The conference sat in four committees which prepared reports, all of which were adopted, unanimously. One was on Imperial commercial relations, of which Mr Fernie was a member, another was on international payments, of which Mr Jacobs was a member, a third was on primary production and secondary industries,, on which Mr Johnston sat, and the fourth was on communications. In addition to giving emphatic support to Imperial preference and accepting the Bretton Woods proposals, subjectto a plenary, session in four to five years to review the position, the federation welcomed the establishment of a permanent "international food and agricultural organisation. It was of the opinion secondary industries must be based on sound economic considerations. Commonwealth countries should help mutually in their promotion reestablishing assembly or production units interchange of selected technical and skilled personnel, and closer personal contacts, it was stated. The federation considers that interstate cable rates within the Frnpire is a domestic matter and should not br> subject to international discussion at the Her mud a conference.
