The Vertical Cooker is a specialized heating and conditioning equipment widely used in oilseed pretreatment lines. It is mainly applied before mechanical pressing or solvent extraction to adjust the temperature and moisture content of oil-bearing materials. By steaming and conditioning the flakes or crushed oilseeds, the vertical cooker softens the cellular structure, making oil release easier and improving the efficiency of the subsequent oil extraction process.

Technical Parameters of Vertical Cooker

Vertical Cooker Features

Multi-layer vertical structure with steam heating sections, ensuring gradual and even cooking.

Equipped with automatic temperature and moisture control system.

Robust construction with long service life and easy maintenance.

Continuous feeding and discharging system for stable operation.

Can be integrated with oil pressing or solvent extraction production lines.

Applications in Oilseed Processing

The vertical cooker is installed after flaking or crushing machines and before oil pressing or solvent extraction equipment. It plays a vital role in processing oil-bearing materials such as soybean, rapeseed, cottonseed, sunflower seed, peanut, sesame, corn germ, and rice bran.

This equipment is essential when:

1. Preparing for Solvent Extraction – Proper heating ensures better solvent penetration and reduces residual oil in meal.
2. Preparing for Mechanical Pressing – Cooking increases plasticity of flakes, reduces resistance, and improves pressing efficiency.
3. Processing High-Fiber or Difficult Seeds – Materials like cottonseed and sunflower seed require precise conditioning to achieve high oil yield.

Why Use a Vertical Cooker?

1、Enhanced Oil Yield – Cooking destroys oilseed cell walls, enabling more complete oil release.

2、Moisture and Temperature Control – Ensures optimal conditions for pressing and extraction.

3、Improved Meal Quality – Prevents overcooking and ensures consistent protein quality in meal for feed use.

4、Energy Efficiency – Vertical design allows continuous cooking with less steam consumption.

5、Adaptability – Suitable for a wide variety of oilseeds and different processing scales.
