Cider Makinz-

There are manv classes of filters in use, but no doubt the one most 

 approved for large quantities is that known as the " Invicta " (No. 11). 

 and when cider niakinf>- is entered upon 

 on a large scale, it is advisable to 

 procure this filter. The Department 

 imported one of these with its cider 

 plant, the piice being £85 in London. 

 For small growers it is expensive, but 

 Avhen co-operation is adopted, and 

 that system of treating tlie products 

 of the orchard cannot be too strongly 

 impressed upon growers, it will then be 

 found possible nud desirable to obtain 

 this and other modern a])p]iances. 



Other less expensive filters are 

 available, and will be found to meet 

 the requirements of small growers. 

 Messrs. Dondey and Testro, of South 

 Melbourne, have perfected a filter (No. 

 12) which will serve the purpose for 

 small or large makers admirably. It 

 has been subjected to a severe test, both 

 in fermented ciders and in uniermented 

 juice, and I have no hesitation in 

 stating that it will meet all require- 

 ments at half the co^t of the above.

Pasteurizing. 



This term is given in honour of the eminent French scientist, Pasteur, 

 and his system appears tO' be well adapted to light liquors, such as cider, 

 which have a tendencv, when the slightest cause is given, to pass on from 

 the vinous to the acetous fermentation. 



Pasteurizing consists of raising the temperature of the liquid after fer- 

 mentation from 140 to 160 degrees Fahr., keeping it within these limits for 

 a given time, say, two hours, restricting its duration at the highest point 

 for a very few minutes, and scrupulously guarding against allowing the 

 air to come into contact with it after this treatment. 



13. pasteurizer for bottled liquids. 



The simplest and most general plan is that adopted and recommended by 

 the English cider makers. The accompanying illustration (No. 13) shows 

 the appliances employed. These are made by the firm of L. Lumley and 

 Companv, London. 



When large quantities are being treated, the other design (No. 14) may 

 be of more advantage, but the cost is much greater.
