Oilseed steam cooker

The process in which oilseed flakes are treated through moisturizing, steaming, and frying to transform raw flakes into cooked flakes is called conditioning (or cooking). Conditioning is a crucial step in the oil pressing process.

Through the combined action of heat and moisture, the flakes undergo significant changes in their micro-ecology, chemical composition, and physical properties. This treatment enhances oil yield while improving the quality of both the extracted oil and the oil cake. During conditioning, oil-bearing cells are thoroughly destroyed, proteins are denatured, oils are released and aggregated, the viscosity and surface tension of the oil are reduced, the elasticity and plasticity of the flakes are adjusted, and enzyme activity is deactivated.

Types of steam cooker

Dry steaming and frying: Dry steaming and frying only heats and dries the material or oil without wetting it. This steaming and frying method is only used for steaming and frying special oils, such as frying sesame seeds when making small-milled sesame oil, frying peanut kernels when making strong-flavored peanut oil, etc.

Wet steaming and frying: Wet steaming and frying means spraying hot water or directly passing steam into the raw embryo after rolling and kneading to keep the oilseed at a certain humidity, and then steaming and frying the wet embryo to make the moisture, temperature and tissue properties of the cooked embryo after steaming and frying most suitable for the requirements of oil extraction. Wet steaming and frying is currently a commonly used steaming and frying method in oilseed production plants.

Steaming and frying is one of the important processes in the oil production process. Due to the effects of moisture and temperature, steaming and frying can greatly change the internal structure of oil, and these changes are not only conducive to the separation of oil from oil, but also conducive to accelerating the improvement of crude oil quality. Therefore, the quality of steaming and frying directly affects the smooth progress of the entire oil production process, the oil yield, and the quality of oil products and cakes. Steaming and frying equipment includes layered steaming and frying pans, hot air seed frying machines, etc.

Advantages of steaming and frying:

1. Allow the oil cells to absorb water and expand, thereby breaking the oil cell walls and opening the oil outlet channel;

2. Change the properties of protein in oil, separate oil from protein, and condense oil from tiny particles into larger oil droplets;

3. Change the plasticity of oil to meet the requirements of oil press for oil plasticity;

4. As the temperature rises, the viscosity of the oil decreases, which is more conducive to the release of the oil.
