The biscuit oil spraying machine is an essential auxiliary equipment in a biscuit production line, designed to evenly spray edible oil on the surface of cookies after baking. The oil coating gives biscuits a glossy, moist appearance while enhancing their crispness and flavor. Made of food-grade stainless steel, the machine meets international hygiene standards and is widely used in cookie production lines, soda biscuit lines, and automatic biscuit making machines.
This machine adopts a stainless steel centrifugal disc oil injection system, capable of spraying oil simultaneously on both the upper and lower surfaces of biscuits. Equipped with an oil mist collection system, it ensures uniform oil distribution while maintaining a clean working environment with minimal oil mist pollution.

Oil Supply System: Stainless steel oil tank or external pipeline with oil pump to ensure stable and continuous supply.
Atomization Mechanism: Pressure atomization and air-assisted atomization deliver fine, uniform oil mist for better coating.
Injection Control: Adjustable nozzles for angle and direction, suitable for different biscuit shapes and sizes.
Automation Control: Integrated PLC control synchronizes with the biscuit production line, automatically adjusting spray timing and volume.
Eco-Friendly Design: Equipped with an oil mist collection system, ensuring a clean and pollution-free production environment.
