Oilseed steam cooker

The process of transforming the raw material of oil-bearing into cooked material after wetting, steaming and frying is called steaming and frying. Steaming and frying is a very important process in the production of oil extraction.

The purpose is to change the micro-ecology, chemical composition and physical state of the material through the effects of temperature and moisture, so as to increase the oil extraction rate and improve the quality of oil and cake. Steaming and frying completely destroys the oil cells, denatures the protein, aggregates the oil, reduces the viscosity and surface tension of the oil, adjusts the elasticity and plasticity of the material, and inactivates the enzymes.

Types of Steaming and Stir-frying

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 oilseed steam cooker:

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.
