HOW DOES IT WORK?

In machine dish washing, dishes which are properly placed in suitable dish carrying racks, are sprayed with hot approximately 60 degrees centigrade detergent water from top and bottom through properly located and well engineered nozzles with the help of a pump.

The scrubbing action of the water sprayed coupled with the cleaning action of the hot detergent solution is sufficient to remove the fact well and food particles and food Stains from plates, cups, glasses, trays, cutlery, Thalis, hollow ware.

Invariably, to save detergent, water and he candidly this water is recirculated.

Two standardized the dishes, a small quantity of fresh water sprayed approximately 80 degrees centigrade from top and bottom for the shorter duration is provided as the final wash.

The final rinse water is added to that the circulating solution.  This enables the degeneration of that the circulating of wash water by taking out the oil slick through the overflow pipe.  The allegation of the high-temperature final rinse water to the three circulating of wash water also aids in arresting the fall of wash water temperature due to the spraying action and sales and energy(final rinse water being at a higher temperature)

What Is the Sequence of Operation?

Dirty dishes are brought to the soil the dish- landing table.  The leftover food is hand scraped from the flat surfaces into a garbage bin.  The liquids are drained into the sink, cutlery is placed into a bowl containing detergent solution to loosen the stack food.

Plates, glasses, cups are stacked in the proper position in specially designed plastic dish carrying baskets(called dish racks). Sorting and placing dishes in racks meant for flat where, hollow ware and cutlery reduces breakage and more importantly allows water sprayed to reach all parts of the ware for good cleaning results.  (Upside down glasses and cups ensured that water runs of after washing) the dishes are the three watched over the sink with a hand operated charmer of water at ambient temperature (preferably warm) to remove solid stuck food and to loosen in the soil. This operation is very important in getting food washing results in the machine.  The racks are then placed in the dish washing machines when the washing is done as described above. 

What can be watched in dish washing machines?

Most dish washing machines will wash broccoli, cutlery and hollow ware made of China, mellow mine, Stone, stainless steel, glass and silver.  Parts and pans are difficult to wash in the usual dishwashers due to their size and the fact that they need more vigorous hand scrubbing.  Lightly soil small pots and pans can invariably be washed.

Why buy a dish washing machines?

For dish washing activity of any size, machine dish washing save manpower, energy, water, detergent, space and reduces breakage by giving consistent washing results.

With greater awareness of hygiene you need well washed dishes in any catering establishment.  Noel dish washing games in consistent results it was it requires large space which is nowadays very expensive particularly when the number of dishes to be watched is high.  It also requires many persons to do the job in a short time span available for this activity.  Many persons in a small space are difficult to accommodate leading to increase breakage, were washing and related personnel problems.

Noel dish washing buy large number of persons leads to higher consumption of detergent, water and heat energy.  All these factors are controlled by building in electric/electronic controls in the machine.

Do you need skilled persons to operate the machine?

Buying skilled persons are not required to run these machines it is very important that the operators are properly trained in following the sequence of operations to get the best washing results and few breakdowns.  It is necessary for them to follow a small set of instructions.

However upgraded machines are now being made available which would alert operator to any malfunction and negligence on this part.  If he continues to be negligent, the machine would stop operating to prevent breakdowns and waste of energy.

What needs to be done to get the machine ready for operation?

It is very important that the machine interiors are kept clean.  This should be done at the end of each wash period as it is easiest at that time and it prevents the TV of growth and foul odours during non use periods.

In most machines the operator has to check that the tank grained valves are closed and fresh water will remain in the tank during filling.

Next he has to fill the water tank to the desired level (automatic level control option available)

he then needs to add detergent (automatic dispensing option available) and start deleting process through electric heaters or steam (automatic switching on option available)

when the desired temperature of the watched and rinse water is reached as indicated by the thermometers the machine is ready for washing and he can switch on the pumps for water sprayed and load the machine with dish is placed in suitable racks as described above.

Do the dishes come out dry?

No, the dishes do not come out absolutely dry.  The temperature of the dishes is quite high as the washing sequence gets over.  When the dishes come out of the machine there may be a few drops of water on the dishes.  However the absorbed heat in the dishes helps in evaporating the water droplets away.  If the water has hardness salts these mealy spots which required by the with the soft cloth.

Does a drier help?

The drier helps in sanitising the dishes by enveloping them in hot air.
