a conveyor belt (102) to move along the closed path, the conveyor belt (102) comprising a plurality of moulds installed thereon, wherein the conveyor belt (102) is to move the plurality of moulds across the plurality of subassemblies of the soap processing assembly (102), each of the plurality of moulds being a two-part mould,
wherein the plurality of subassemblies comprise:
a mould closing subassembly (104) to close each of the plurality of moulds by aligning a first part of each of the plurality of moulds with a corresponding second part of each of the plurality of moulds;
a filling subassembly (106) comprising one or more filling nozzle to fill molten soap into each of the plurality of moulds; and
a cooling subassembly (110) to cool each of the plurality of moulds at a predefined temperature for the solidification of soap bars.

2. The soap processing assembly (100) as claimed in claim 1 further comprising:
a cutting and opening subassembly (112) to cut riser of each of the plurality of solidified soap bars, and to open each of the plurality of moulds to eject a corresponding soap bar from each of the plurality of moulds.

3. The soap processing assembly (100) as claimed in claim 2, wherein the cutting and opening subassembly (112) comprises a cam profile to:
push inbuilt blades of each of the plurality of moulds across a corresponding mould cavity to cut the riser of each of the solidified soap bars; and
disengage the first part of each of the plurality of moulds with the corresponding second part each of the plurality of moulds to eject the corresponding soap bars.

4. The soap processing assembly (100) as claimed in claim 1, further comprising a washing subassembly stationed to wash inner surface of the first part of each of the plurality of moulds and inner surface of the second part of each of the plurality of moulds.

5. The soap processing assembly (100) as claimed in claim 4, wherein the washing subassembly further comprises scrubbing brushes to clean the inner surface of the first part of each of the plurality of moulds and inner surface of the second part of each of the plurality of moulds.

6. The soap processing assembly (100) as claimed in claim 1, wherein inner surface of each of the plurality of moulds is at least one of electroplated and polished with a microscopic layer of a metal of a predefined thickness.

7. The soap processing assembly (100) as claimed in claim 6, wherein the metal is Nickel (Ni).

8. The soap processing assembly (100) as claimed in claim 6, wherein the predefined thickness is from about 3 micrometer (µm) to about 6 µm.

9. The soap processing assembly (100) as claimed in claim 1, wherein the predefined temperature is from about 250 Celsius (C) to about 350 C.

10. The soap processing assembly (100) as claimed in claim 1, wherein the cooling subassembly (110) comprises an air handling unit to manage amount of air to cool each of the plurality of moulds, wherein the air handling unit comprises:
a chiller to reduce the temperature of each of the plurality of moulds; and
a blower to provide air flow to each of the plurality of moulds.

11. The soap processing assembly (100) as claimed in claim 1, wherein the filling subassembly (106) comprises a hot chamber to
heat the molten soap at a predefined temperature; and
maintain the molten soap above the predefined temperature to minimize air entrapment of bubbles in the molten soap.

12. The soap processing assembly (100) as claimed in claim 11, wherein the predefined temperature is 600 C to 750 C.
13. The soap processing assembly (100) as claimed in claim 1, wherein the closed path is one of an elliptical path and a substantially circular path.
