The PLC Controlled Automatic Roasted Peanut Coating and Coated Snack Production Line is designed for efficient commercial production of crispy coated peanuts and other snack foods. The system integrates automatic feeding, liquid spraying, powder dosing, coating, roasting, seasoning, drying and cooling into a streamlined production process. PLC control allows key operating parameters to be adjusted according to different products and recipes, helping maintain stable coating thickness, roasting temperature and processing consistency.
The line can be configured for dry roasted peanuts, flour-coated peanuts, fish-skin peanuts, Japanese-style peanuts, coated almonds, cashews, broad beans, green beans and other suitable snack products. Automatic liquid and powder feeding systems reduce manual operation while supporting consistent coating results. Multi-stage coating can be selected when a thicker and crispier outer layer is required. The complete system can be customized according to raw material, coating formula, production capacity, heating method and packaging requirements, making it suitable for professional snack food manufacturers.

Standard Process
Feeding → Liquid Spraying → Powder/Flour Dosing → Coating → Sieving → Roasting → Seasoning → Drying → Cooling → Packaging
Multi-Stage Coating Process
Feeding → First Liquid Spraying → First Powder Coating → Tumbling → Roasting → Cooling → Second Liquid Spraying → Second Powder Coating → Final Roasting → Seasoning → Drying → Cooling → Packaging
The exact process can be adjusted according to whether the target product is a light flour coating, thick fish-skin coating, flavored peanut or another coated snack.
PLC Control System
The PLC control system can coordinate major processing parameters, including:
Liquid spraying time
Powder feeding quantity
Coating cycle
Material conveying speed
Roasting temperature
Roasting time
Seasoning quantity
Drying conditions
Cooling time
Some commercial coating systems specifically use PLC control for adjustable liquid and powder dosing parameters, supporting repeatable production between batches.
Main Equipment
