Raw milk is brought to these depots daily in rail tanks of 3,000 gallons
capacity and also in road tankers each holding the same amount. Milk is collected
from the farms and bulked at creamery centres in the dairying areas and after
preliminary tests it is despatched to the processing and distributing depots. A
large quantity of milk is also received at these depots in churns direct from the
farms. The two depots handle altogether about 180,000 gallons of milk per day.
There are nine "high temperature—short time" pasteurising plants in which the
milk is heated to, and retained at, a temperature of 161 °F. for 15 seconds, and is
then cooled to below 50°F. in accordance with the requirements of the Milk (Special
Designation) Regulations 1960-1963. There are also a number of ovens for the
production of sterilised milk.
Some of the milk is distributed in churns after pasteurisation, about 12,000
gallons is sterilised in bottles and the remainder is bottled or filled into cartons
after pasteurisation. At one of these depots extensive cartoning of milk is now
carried out and a variety of types of carton are filled for supply by retail sale,
especially in milk vending machines.
At regular intervals the Food and Drugs Inspector checks the efficiency and
working temperatures of the processing plants and takes samples to ensure that
they comply with the requirements of the Milk (Special Designation) Regulations,
1960-1963.
All samples taken from these milk plants were reported to be satisfactory.

the premises were found to be satisfactory.
