Uniform Roasting Technology for Taste and Texture
Roasting is essential for developing flavor, reducing moisture, and sterilizing food products. Ven-Tech Systems manufactures Rotary Drum Roasters that provide a consistent roast, eliminating the risk of “spot burning” common in manual or static roasting methods.
Batch and Continuous Roasting Systems
Working Principle:
The material is fed into a rotating drum fitted with internal helical flights. These flights continuously lift and tumble the product, ensuring that every individual grain or nut is exposed to the heating surface and hot air stream evenly.
Key Features:
- Heating Source: Available in LPG/Natural Gas fired models (for economy) and Electric models (for precision). We also offer advanced Induction Heating options for rapid start-up and high energy efficiency.1
- Insulation: The drum is encased in a double-walled insulated housing to prevent heat loss, significantly reducing fuel consumption.
- Control: PLC-based controls allow operators to set specific temperature profiles and residence times for different recipes (e.g., light roast for cashews vs. dark roast for coffee).
Applications:
- Vermicelli: Continuous roasting for uniform browning and texture, a critical process for MTR’s vermicelli products.
- Nuts: Roasting peanuts, almonds, and cashews for the confectionery industry.
- Spices: Pre-roasting coriander and cumin before grinding to enhance the “nutty” flavor profile.
