A dish washer is a mechanical device which is used for cleaning dishware and cutlery. It operates a few automated steps in sequence. The set process whereby the appliance heats water to the desired temperature sprays the dirty utensils with a mix of water and detergent for a wash, drains the dirty water, pumps in fresh hot water for rinsing and assists in air or heat drying of utensils is referred to as “dish washing”.
Manual steps required for dish washing:
1 – Food is scraped off the dishes,
2 – Dishes are then loaded on the dish washer racks,
3 – Dish washer detergent is added, and the device is then turned on to clean the dishes.
4 – Post sanitation, the dishes are removed.
The steps may vary depending on the make and model of the dish washer in operation.
Modes in which typical dish washers operate:
Intensive mode:-This mode is used for the heaviest soiled dishes which have been lying with dried food on them for a while. Casserole dishes, pans, and pots are examples of utensils on which this mode is used.
Auto mode:- This mode is used for utensils which are soiled but which can be cleaned with regular force. This is the most widely used mode.
Economy mode:- This mode is used for lightly soiled loads such as plates, glasses, bowls and lightly soiled pots.
Delicate mode:- This is used for fragile items like glass utensils.
Pre-wash mode:- This mode is used for pre-cleaned dishes. This is just a re-cleaning mechanism in which detergent is not dispensed.
Quick wash mode:- This is a quick wash for lightly soiled utensils not requiring wash.
Low acceptability of dish washers in India:-
Statistics prove that only 1 out of 100 households in India use dish washers compared to 2 out of 3 households in European countries.
There remains a misconception in the minds of Indian households whether dish washers would be able to clean up the stains of spices and oils used for the preparation of Indian food. However as per facts presented, dish washers are well equipped to wash woks, pressure cookers and pots perfectly clean if proper detergents are used.
Types of Dishwashers available in India:-
A variety of dish washers are available in India in current times.
Built in dish washers:- These are built into the cabinets, and their positions cannot be changed.
Free standing dish washers:- These are floor standing dish washers, 24 inches or 60 centimetres wide. These can be placed anywhere depending on water connection, drainage point or electric point. The standard Indian size of these dish washers is 60 centimetres wide, 60 centimetres deep and 85 centimetres high.
Counter top dishwasher:-These are most popular dish washers in India. They are the cheapest and do not require any plumbing. These are a perfect fit for small families where the count of utensils is not very high.
Factors to be considered while purchasing a dish washer:-
Capacity:- The capacity of the dish washer is an important factor to be considered. This depends on various factors such as:
- Family size- Number of family members and likely additions.
- Food habits- Traditional Indian cooking requires bigger and heavier utensils.
- Guests- Frequency and number of guests visiting home.
Cycle time:- Cycle time defines the time taken by the dishwasher to complete one cycle. This can be manually adjusted making the process energy efficient. It depends on the number of utensils loaded and greasiness of the utensils. A larger cycle is required if the count of utensils is more or if the utensils are greasier.
Wash programmes:- A dishwasher is considered to be more versatile if higher number of wash programmes are available. However, the higher the number of programs the higher the price. It is important to maintain a balance between price and quality at the time of selection of a dish washer.
Type of utensils used:- In Indian families the use of stainless steel plates and cutlery is still prevalent. The type of utensils used is an important factor while deciding the dish washer.
Quality of water:- There are a lot of places in India where the quality of water is very hard. Hard water gives rise to the problem of scaling and reduces the strength and effectiveness of detergent being used. Dish washers compatible with hard water which can effectively convert hard water to soft water before washing starts should be considered based on the type of water.
Temperature range:- This refers to the range available in the inbuilt heater present in the dish washer. This enables selection of lesser temperature for lighter loads and higher selection for heavier loads, thereby saving electricity cost.
Benefits of using dish washers:-
Saves water- The quantum of water required for hand-washing utensils at a sink is far greater than water used by a dish washer. This is because a dish washer recycles and filters small amounts of water.
Saves time and effort:-The Washing utensils manually takes a lot of time and effort. Whereas time required for dish washing is primarily for loading, unloading and placing settings.
Saves energy:- Dish washers in use heat water only to the extent and temperature they require. This does not require heating in water tanks or central heating system where there are chances of heat getting lost in transit.
Lighter on pocket:- Dish washers use lesser water and energy than washing the same load by hand. With expensive electricity in current times, these savings can actually lower the electricity bills.
Hygienic wash:- Dish washer uses higher temperature of the water that what human hands can cope. Use of heated water along with a strong detergent can be a better protection from harmful germs and bacteria that can build u
p on dish cloths, kitchen towels and sponges.
Clutter free kitchen:- It’s unsightly, bad smelling and unhygienic to have dirty unwashed utensils piled up in the kitchen. With an effective dish washer in place, a clean kitchen is a big advantage.
Sparkling dishes:- Detergents used for dish washer wash contain far more active ingredients than hand washing liquids thereby ensuring food soils are properly broken down and washed away during the washing cycle to leave the utensils shiny. Latent heat on dishes and rinse agents ensure utensils washed come out with a wonderful shine and free from spot marks and streaks which is quite visible in hand washed utensils.
