The invention discloses a device and a method for detecting the squeezing performance of a vegetable oil material. The device comprises a base, wherein an outer barrel and an inner barrel are coaxially sleeved on the base; an annular space is formed between the outer barrel and the inner barrel; a loading piston structure is arranged inside the annular space; holes which are uniformly and densely distributed are formed in the wall of the outer barrel; and the detecting method comprises the step of recording the oil outlet pressure and strain at the time when oil outlet points are detected in the holes by a thin oil-absorbing sheet. According to the device and the method disclosed by the invention, a squeezing process of a spiral oil press or a hydraulic oil press is accurately simulated to research a stress and strain relationship of different squeezed oil materials under different pressures, to represent the characteristics of different oil materials, particularly volume pressure infiltration characteristic associated with oil squeezing, so that relative feasibility of various alternative pretreatment schemes is estimated before squeezing the oil materials, and basic data is provided for researching and developing a novel spiral oil press.
Description
technical field [0001] The invention relates to a technology for detecting the pressing performance of vegetable oil, in particular to a device for detecting the pressing performance of vegetable oil and a detection method thereof. Background technique [0002] The most commonly used method of extracting oil from oily plant seeds (ie oil plants) is mechanical pressing, and commonly used oil pressing equipment includes screw presses and hydraulic oil presses. During mechanical pressing, the oil can be directly cold-pressed without any pretreatment, or can be pressed after a certain pretreatment before pressing, such as crushing, flaking, steaming and conditioning, etc., no matter which method, Squeezable fluid separation is essentially achieved through gradual compression and deformation of granular oil particles under the action of external pressure. Oil in oilseeds is usually dispersed in different positions in oilseed kernel cells in the form of tiny oil droplets, togethe...
