Abstract:
Washing plates normally done by hand and it uses water, energy, chemicals as well as
need to spend valuable time. So an efficient approach can save a lot of time as well as
chemicals. Though the dish washing machine gives some relief for that, the existing
dishwashing machines in the world market consist many defects in the process such
as wastage of water, requirement of man power, high installation cost, poor quality of
cleaning etc. Specially, there is no proper turning off system after the washing had
been completed. Hence it takes more than one hour to complete one cycle of washing
and waste large amount of water.This project is about developing an automated plates
washer,which was having following main objectives, that should be in minimal cost,
user friendly and easy to use. It must give optimum cleaning using least amount of
water and energy. Important objective is turning off the system when the plates are
cleaned, without wasting time and water. The system controlled by arduino and has to
supply high pressure water to the machine in order to start the washing process. Initially need to spray soapy liquid to the plates. A D.C motor had been used to drive
the system. Outlet removes all the waste water and there is a PH sensor to detect the
quality of the waste water. It can give signal when the PH=7. That is, the water does
not contain any contaminant. It means the plates are cleaned and the machine will be
turned off automatically. Though for normal washing takes about 8 minutes to wash 10
plates, the proposed machine takes only 90 seconds (400 plates per hour).It can develop
using minimal cost of lower than Rs.20,000,without spending Rs.50,000 - Rs.150,000
to buy a plate washing machine from the market. The system is very user friendly. It
can be used in large scale kitchens such as in marriage ceremonies, receptions, business
parties, hospitals and hotels where there is a requirement of more number of plates. Not
only that this plates washer is useful for household usage as same as the washing machine, which can save time and cost rather than spending in washing plates by hand and
wasting large amount of energy. The machine can further developed as fully automated
system, by inserting plates in to the machine, and releasing dried plates and storing them
properly.
