Automatic Dosa Making Machine

Abstract

Bulk preparation of food demands stringent attention to hygiene and quality of the product. Modern lifestyle has no time left for preparations like dosas. Dosas are easy to digest type of food. Automatic Dosa maker will be a useful appliance which will solve all the problems associated with dosa preparation. Automatic Dosa maker is useful for small-scale industries. The cost of the machine is kept low so that it is affordable to many. The machine delivers dosa with the press of a button without any further human intervention. PLC is used where step by step approach is followed for the efficient functioning of the Dosa preparation process leading to automation of the entire process of Dosa making. Manufactured dosas are packaged using a conveyor system. IR Sensor is used for keeping a count of the number of Dosas produced. Implementing a smart monitoring through IoT technique increases the efficiency of the machine, as it can be monitored remotely and can be easily maintained. Ladder logic is developed to program the PLC for the automatic working of the machine. The machine also aims at providing convenient dosas for those who might not be skilled in making dosas or who might not have access to appropriate cooking appliances. The machine was tested and the production rate is found to be one dosa per five minutes. Automatic Dosa maker reduces the time as well as manpower required for preparation of Dosa. Therefore, this machine is an ideal solution for hygienic and low-cost Dosa manufacturing and packaging with built-in security measures. The machine uses state of the art technologies like automation and IoT for its working.
