Another plan ([Fig. 61]) shows the arrangement of a Cheddar cheese factory without the whey butter apparatus. The location of the drain between the vats might be criticized. In Fig. 62 is shown the arrangement of a combined butter and cheese factory. Fig. 63 shows the possible arrangement of a Limburger factory. The size of this factory could be reduced by having the salting tables closer together.

In a Cheddar cheese factory, the curing-room may be over the manufacturing room. This makes considerable work in carrying the cheese up and down. A small elevator may be used for this purpose. The same principle holds in cheese factories in which other varieties of cheese are made; the floors should be on one level so far as possible. There is danger of the overhead curing-room becoming too hot and causing the cheese to leak fat. Shelves or tables should be provided on which to put and keep the utensils. The utensils should never be placed on the floor.

294. Arrangements for cleanliness.—A sink for washing the utensils should be provided and boiling water to scald them after washing. After being scalded, tin utensils dry quickly without rusting. The boiling water may be obtained by placing a steam pipe in a barrel of water and turning on the steam. The utensils can then be washed clean, dipped in this barrel of boiling water and put in their place. Too much emphasis cannot be laid on keeping the factory itself, the utensils and the surroundings clean. This will prevent the development of mold. Cases are known in which the cheese factory was allowed to become very dirty, so that a red mold developed. This eventually got into the cheese and caused red spots.[131] They are called rust spots. All doors and windows should be screened to keep out flies.
