Multipurpose Continuous Frying System for Namkeen is designed to handle a wide variety of snacks—ranging from light, floating items like Sev and Boondi to heavy, non-floating items like Chana Dal and Peanuts—all in a single machine.

The "multipurpose" capability comes from the Variable Frequency Drive (VFD), which allows you to adjust the frying time and belt speed precisely for each unique product.

1. Technical Specifications (Standard Multipurpose Model)

2. What makes it "Multipurpose"?

To fry different items successfully, the system uses three critical design features:

• Dual-Belt Conveyor System:
• Submerger Belt: Essential for floating items (like Gathiya, Papdi, and Fryums) to keep them under the oil for even cooking.
• Take-out Belt: A fine mesh belt that ensures even the smallest items (like Nylon Sev or Boondi) are collected and removed without breakage.
• Adjustable Flow Control: Multiple oil inlets allow the operator to control the "push" of the oil. For light snacks, you need a gentle flow; for heavy pulses like Moong Dal, you need higher circulation to keep them moving.
• VFD Speed Control: The "Variable Frequency Drive" allows you to change the belt speed via a touchscreen. You can fry Potato Chips in 3 minutes and then switch to Moong Dal which may require 6 minutes, just by changing a setting.

3. Integrated Components

1. Gear Motor Hood Lifting: The entire top conveyor hood can be lifted automatically using air cylinders. This is crucial for multipurpose use because you need to clean the machine thoroughly when switching between different products (e.g., from spicy Bhujia to plain Boondi).
2. Continuous Oil Filtration: A rotating drum or belt filter removes "fines" (broken pieces) instantly. This is vital for Namkeen because Besan (gram flour) leaves a lot of residue that can burn and spoil the oil.
3. Oil Cooling & Storage Tank: Includes a "Day Tank" that can hold all the oil from the system. It often features a cooling jacket to prevent the oil from oxidizing when the machine is shut down.
4. Automatic Oil Topping: A sensor detects when oil levels drop (due to absorption by the snack) and automatically pumps fresh oil from the storage tank into the fryer.

5. Benefits for the Manufacturer

• Minimal Oil Degradation: The high Oil Turnover Ratio (OTR) means you are always adding fresh oil, keeping the "Acid Value" low.
• Labor Efficiency: A multipurpose continuous line typically requires only 2 operators, compared to 6–8 for a batch frying setup of the same capacity.
• Fuel Savings: Indirect heating via a heat exchanger is roughly 30% more efficient than direct-fired pans.
