Objective –

To change the milk’s form, from liquid to viscous by automatic stirring ,using solar energy from parabolic reflector.It will reduce fuel and human drudgery.Basundi is one of the sweet dish, it’s very popular sweet dish in all over India and it is made by adding the sugar into dense milk.We have to stir and observe continuously for condensation of milk so it requires lot of efforts and time.
                  

               liquid milk                                                                   viscous milk

we observed-

That if we use parabolic reflector for cooking then its cause to save fuel and it is low cost concentrator.But it is not possible to cook on parabolic reflector by standing in front of that continuously as it creates heat and the rays reflected from its surface can injure our eyes.So automation is require to avoid that problem.

Today’s  market condition –

Machine available in market for this process has facility to stir continuous but one person is needed for observing the state of milk.There is no such a machine in market which uses solar reflection heat for this  process and there is no machine which indicates the dense state of milk

Change due to Basundi maker

This machine can make basundi easily without giving your time for all process and it will reduce fuel cost.Just start machine and forget it, machine will automatically give alarm when your Basundi will get ready
Input-Load sensor or level sensor or current sensor with stir assembly
Output – machine will give alarm when milk will convert to viscous form.

Process-

Need one pot. Put 5ltr milk into pot add stir and switch on the supply then stirring will get start and then leave it,
because due to stirring process and continuous heating, milk will become dense .Sensor will recognize the state of milk.When density will reach to required point then buzzer will be blown.
