Too Report on the Miscellaneous Implements

The Ayleshiirij Dairy Company showed two "Danish" milk 
heaters, one (Ai-t. 723) for whole-milk, the other (Art. 722) for 
skim-milk. The heater for whole-milk is designed for raising 
the temperature of the milk before it is allowed to run into the 
separator. The " Danish " separator skims cold as effectually as 
warm milk, but, in order that separation may proceed at the 
maximum speed, it is desirable that the milk shall enter the 
separator at a temperature of about 77°. If over-heated the 
flavour of the cream is injured. 
The heatei- consists of a tinned-copper drum, fitted with a revolving 
stirrer, and suspended, steam-tifrbt, in a wooden cask. The cask has an 
inlet and an outlet for steam, and forms a steam jacket. The whole is placed 
between the milk-tank and the separator, and the inflow and outflow of 
milk are regulated by t'le floats K and C shown in the drawing. The stirrer 
having been set in motion, and the cock of the tank opened, the milk enters 
the copper drum, and is set in motion by the stirrer. When the drum is 
full of milk, steam is turned on, and the warm millc, leaving the drum through 
the spout E, is conducted through the inflow regulator, B, into the separator. 
Should the inflow exceed what is required, the float 0 cuts off" the supply 
from the heater, causing the milk to rise in the latter and in the pipe L, 
thus operating on the lioat K, and shutting ofl' the supply coming from the 
milk-tanks until the level of the millc in the drum is reduced. Only the exact 
quantity of milk required to feed the separator is thus allowed to enter the 
heater ; and, since this quantity remains constant at a given adjustment of 
the inflow regulator, B, it is easy to adjust the amount of steam required to 
heat the milk to the desired temperature,
