Description

Technical Field

[0001] The present invention relates to the technical field of edible oil extraction, in particular to edible oil extraction equipment and a process thereof. Background Art

[0002] There are many methods for extracting tea oil, among which pressing is the most widely used method for tea oil, which can effectively ensure the aroma and nutritional components of tea oil. However, during the extraction process of tea oil, the pressing plate only acts on the linear movement of the pressed tea oil cake, so the tea oil can only flow naturally downward into the oil tank, which will cause most of the tea oil to remain on the pressing plate, and it takes more time to squeeze out the tea oil in the tea oil cake, which is not convenient for the extraction and collection of tea oil.

[0003] To this end, a Chinese patent with publication number "CN118909692B" announced "an edible oil extraction device and process thereof", whose main structure includes: a top frame, fixedly connected to the base, wherein an extraction barrel is rotatably mounted on the base, and stacked pressure plates are provided in the extraction barrel, and a driving part for driving the extraction barrel to rotate is provided on the base; a lifting device fixedly mounted on the top frame, wherein a pressure block facing the extraction barrel is rotatably mounted on the telescopic end of the lifting device; the edible oil extraction device and process thereof can make the tea oil on the pressure plate efficiently collected into the extraction barrel under the action of centrifugal force, and the tea oil in the tea oil cake will also be discharged more efficiently, thereby improving the extraction efficiency of the tea oil.

[0004] The power source of this edible oil extraction equipment comes from two points: first, hydraulic equipment is used to press the tea oil cake so that the tea oil can be squeezed out; second, a drive motor is used to drive the tea oil cake to rotate rapidly, so that the tea oil is thrown around under the action of centrifugal force, thereby improving the extraction efficiency of the tea oil. Since the two effects require two kinds of power, the effective utilization rate of kinetic energy is relatively low, resulting in increased use costs. In addition, the tea oil cakes are stacked vertically, and axial compression will result in a longer compression stroke, and a long compression stroke will lead to reduced extraction efficiency.
