Three types on the basis of working:
A. Spray Type: Dishes are neatly stacked in racks which slide into the machines where they are sprayed with hot water and
detergents (48 degree C-60 degree C) from above and below. The rack then moves to the sterilization section where the dishes are subjected to a hot water shower (of 82 degree C).Dishes sterilized at this temperature dry quickly when passed out into the air.
B. Brush type: dishes are scrubbed in hot detergent water (48-60 degree C) with revolving brushes. Then they are rinsed
and sterilized in another section of the machine.
C. Agitator water machine: In this method, baskets of dishes are immersed in deep tanks and cleaned by mechanical
agitation in hot detergent water. The baskets are given a final hot water rinse for sanitization.(82degree C).These machines
are usually operated by two people, one for sorting soiled items and to feed the machine and the other to collect the cleanware.
2. Burnishing machine: There is a large drum which is half filled with ball bearings and there is a rod in the center used for putting the handles of the cups and jugs. The cutlery is directly put into the drum. The soap solution is added to avoid friction which could cause scratches. This machine is either attached to a water supply or else water is poured manually. The machine takes around 15 min to complete the polishing process.
3. Silver plating machines: there is a separate room that is used as the silver plating room where machines are used to
electroplate the silver articles.
