The laddu making machine should be semi-automatic. The machine should be safe and hygienic. It should be as compact as possible and portable. The machine should make 1-2 laddus simultaneously. The dough balls should have a diameter of about 2.5 cm. The machine should be ready in about 3 mounts and the budget is Rs.5000. The machine should have a container to store the laddu dough that is manually provided. Then it should make chunks of the laddu dough, then shape it and collect it in a container.
This invention is useful for moulding of any food material, which has the property of binding particles together. The moulding machine can mould the food material in any geometrical shape such as sphere, square, rectangle, etc. The moulded food materials obtained by using this device of the present invention are of uniform dimension and geometry and are obtained continuously.
During festivals, there is a rise in the demand for sweet products and many times due to limited production, only a few customers are satisfied, so there is a need for automating the process of sweet product making plants. Automating the process will improve productivity. The laddu making machine is one of such machines that helps to ease the process of making laddu. It is a semi-automated machine where the laddu dough is manually put into the machine and once the laddus are ready they are collected in a container.
