Fixed Valve Oil Spraying System
In the food industry, this system is a pneumatic mechanical unit used for precise oil spraying inside relatively small cake molds up to 90 mm in diameter
It is primarily installed on Hadaf Machine Depositor Model 4000
Objectives of the Fixed Valve Oil Spraying System
Uniform oil coating inside the molds
PLC-controlled oil consumption management and waste reduction
Increased efficiency and reduced human intervention compared to manual oil spraying
Main Components of the System
Oil Tank
Oil storage tank equipped with a heating element and thermocouple temperature control
The oil sprayer frame can be adjusted left/right and up/down for precise alignment with the molds
A double-jacketed main oil tank can be manufactured upon request
Fixed Spraying Valve
The valve is fixed above the conveyor path
Oil output volume and spray amount inside the molds are controllable
No mechanical movement exists on the valve itself; spraying is performed through pneumatic cylinders and solenoid valves
Product Conveyor (Front Disc Chain Conveyor)
The product moves beneath the valve while oil is sprayed onto its surface
Advantages and Applications
Uniform and adjustable coating for flavor enhancement or anti-stick purposes
Simple and cost-effective compared to moving or complex spray systems, with low friction
Helps increase product shelf life by creating a protective oil layer
Suitable for medium- to high-speed Yazdi and Shirazi cake production lines
Important Performance Parameters
Oil pressure: determines droplet size and spray intensity
Conveyor speed: synchronized with oil flow rate for uniform coverage
Oil or fat type: suitable viscosity prevents valve clogging
Regular cleaning: prevents clogging of valve holes, nozzles, and grease accumulation
Installation Compatibility
Compatible with Depositor Models 4000 and 6000
Definition and Application
A Depositor is designed to dispense pastry production materials in precise and uniform quantities
Its primary application is in pastry, chocolate, cake, toffee, and ready-dessert production lines
The machine replaces manual depositing, increasing production speed, precision, and consistency
Raw materials (dough, cream, chocolate, and fillings) are transferred from the machine hopper to the molds
Using pneumatic cylinders or precision pumps, a specific amount of material is deposited into each mold or onto the product surface
The machine is capable of handling materials with different densities and viscosities
