Both products require appropriate preparation, forming, frying, cooling and handling processes to achieve consistent quality.
A boondi and nylon sev processing line combines product-specific forming and cooking equipment with suitable conveying, oil-draining, inspection and packaging systems. The exact machine arrangement depends on the product recipe, required capacity and final use.
Yuga-We100 provides industrial conveying systems, vibratory equipment, screening and grading solutions, elevating systems and material-handling equipment that can help connect compatible stages of food-processing operations.
1. Overview of Boondi and Nylon Sev Manufacturing
Namkeen manufacturing involves preparing ingredients, forming the required product shape, cooking or frying, removing excess oil where applicable, cooling and transferring the finished product for packing.
Although boondi and nylon sev can share some supporting equipment, their forming processes are different. Boondi production typically uses a perforated plate or suitable depositing system to form small droplets from batter. Nylon sev uses a press or extruder fitted with fine openings to form thin strands from prepared dough.
Boondi Production
Besan-based batter is prepared and passed through suitable perforations into hot oil, forming small round droplets that are fried and drained.
Nylon Sev Production
Prepared dough is forced through a fine-hole die or press to create thin strands, which are cooked and transferred through appropriate draining and cooling stages.
Product Handling
Conveyors, elevators and vibratory equipment transfer products between suitable processing stages while helping maintain organised production flow.
Finishing and Packaging
After cooling and any required inspection or seasoning, products are transferred to weighing and packaging equipment.
2. Difference Between Boondi and Nylon Sev
Both products are commonly made using gram flour-based formulations, but the consistency of the mixture and forming equipment differ. These differences determine the layout and operating requirements of each line.
| Parameter | Boondi | Nylon Sev |
|---|---|---|
| Product shape | Small, round droplets | Thin, delicate strands |
| Typical mixture | Pourable batter | Dough suitable for pressing or extrusion |
| Forming equipment | Perforated boondi plate or depositing system | Fine-hole sev press or extruder |
| Cooking | Usually fried in a suitable fryer | Usually fried using an appropriate sev frying system |
| Oil management | Draining or deoiling equipment as required | Careful draining and handling to protect thin strands |
| Handling needs | Control product accumulation and transfer | Minimise excessive drops and strand breakage |
Important: Recipes and processing conditions vary by manufacturer. Batter viscosity, dough consistency, perforation size, frying conditions and product dimensions should be established for the intended product before selecting machinery.
3. Complete Boondi Manufacturing Process
