The embryo is processed by adding water (wetting), heating (steaming), drying (frying), etc., and the process of changing from “raw embryo” to “cooked embryo” is called “steaming and frying”. It is a very important process of in the production of pressing oil. The effect and quality of steaming and frying will directly affect the oil extraction rate and the quality of oil and meal.best cold pressed oil for cooking
The role of steaming:
First, it can make the oil more fully prepared;
The second is to reduce the power consumption of oil extraction;
The third is to facilitate the preparation of better quality oil.
It is also three items of condensing oil, adjusting structure and improving oil quality.
The oil exists inside the oilseed cells. In order to make the oil more easily produced, many fine droplets of oil in a dispersed state in the cells must first be condensed into large oil droplets, so that the oil can be sufficient and the oil extraction can be improved.best oil mill
To achieve oil coagulation, it is necessary to fully destroy the oilseed cells and fully denature the protein. The high-humidity, high-temperature steaming and frying process of oilseeds can meet this requirement.oil cold press machine for home
The action of heat and mechanical agitation reduces the viscosity of the oil and the surface bonding force between the oil and the material embryo, making it easier for the fine particles of oil to flow out and separate, and gather into large oil droplets, commonly known as “oil leakage”. copra oil mill
The more complete the protein denaturation, the higher the oil extraction rate. However, protein denaturation cannot exceed the limit. If the steaming and frying temperature is too high (higher than 130 degrees), the coking of the material embryo will reduce the utilization value and oil yield of the cake.hydraulic oil press
