Cooking oil blowing process

● Preform Sorting:The prefabricated parts are fed into the bottle blowing machine. This is usually done through an automated system that places the prefabricated parts in the correct position within the machine.

●Preform Feeding:Preforms are fed into the blow molding machine. This is typically done through an automated system that places the preforms in the correct position within the machine.

●Preform Heating:The preform is heated by an infrared lamp thermal element. This heating process makes the plastic soft and malleable in preparation for the blowing process.

●Bottle Blowing:The heated preforms are then placed into molds where compressed air is used to blow the preform into the shape of the mold, forming the bottle. This step ensures that the bottle has the desired shape and structural integrity.

●Bottle Ejection:After the bottle is formed and cooled, it is removed from the mold. The newly formed bottles are then transferred to the next stage of the production line, usually for inspection and filling.

Why use equipment to produce

Edible oils are a staple of the human diet and include edible oils such as olive oil, blended oils and blended oils.

The filling of oils requires high precision and stringent sanitary measures due to the products' volatility and tendency to adhere to surfaces, leading to drips and leaks. Addressing these challenges, DEMARKhas perfected its core filling technologies while also making targeted improvements to equipment design.

With 30 years of deep commitment to the liquid packaging industry, DEMARK understands the challenges of edible oil packaging. Our technical team has developed tailored solutions, resulting in a blow-fill-cap machine that exceeds expectations in terms of production efficiency, cleanliness, durability, and energy efficiency.

Our recommended products

Automatic Servo Blowing Machine(TP-series)

The machine use continuous rotation system with multiple safety protection devices to ensure the high speed preform feeding.

The preform feeding without turning device,simple structure,convenient maintance, reduce cost of spare part change.

The heating pitch between the preforms is small,effectively using the heating space of the lamp tube,and improving the heating efficiency,saving energy by variable pitch structure.

The water runs directly through the heating channel with air cooling system to protect preform neck from deformation.

Optimize oven air draft and preform surface cooling.Reversible heating box make it more easy to change lamp.

Mould closing adopts CAM linkage,no chain plate pin shaft small size, long service life.

The stepping servo motor ensure high-speed operation and accurate positioning.

Servo motor is used to drive the stretching and blowing station,equipped with high speed precision blowing valve set to achieve high production requirements.

Stainless steel pipe make the air blowing more clean without pollution.

High pressure recycle system reduce power consumption.

Multiple direction positioned for the auto loader make it more flexibly for installation.

The machine is designed to be compact in size.effectively reducing floor space.
