Embodiment 1

[0015] Example 1 Roll grinding method of peanuts

[0016] Now the peanuts are pre-crushed to 20-60 mesh and then roller milled. The roller mill has 2-5 rollers, arrangement: vertical, roller spacing: 0-1mm, particle size: 5-60um , Focus on 20~30um; adjust the pressure between the rollers to be 30~50MPa to control the particle size; roller arc: adjust the roller according to the hardness of different materials, the ability of the roller to resist bending deformation, the roller pressure and the size of the feed particle size, etc. The arc and middle height, the middle height range is between tens of microns to a few millimeters; cooling water is turned on during grinding to prevent the roller temperature from being too high and affecting the material properties. For the pretreated peanut grinding material, the oil was extracted by water enzymatic method, and the oil extraction rate was 91.5%.

Embodiment 2

[0017] Example 2 Roll grinding method of camellia seed

[0018] The oil tea seeds are hulled, pre-crushed to 20-60 mesh, and then roll milled. The number of rollers of the roller mill is 2 to 5 rollers, arrangement: vertical, roller spacing: 0 to 1mm, particle size: 5 ~60um, concentrated at 20~30um; adjust the pressure between the rollers to be 45~65MPa to control the particle size; roller arc: adjust the hardness of different materials, the ability of the roller to resist bending deformation, the roller pressure and the size of the feed particle size, etc. The radius of the roller is between tens of microns and a few millimeters. To facilitate feeding and increase productivity, the roller can be atomized before feeding to make the smooth surface of the roller become rough; grinding Turn on the cooling water at times to prevent the roller temperature from being too high and affecting the material properties. For the pretreated oil-tea camellia seed grinding material, the oil ext...

Embodiment 3

[0019] Example 3 Roll grinding method of walnut

[0020] The walnuts are pre-crushed to 20-60 mesh and then roll milled. The roller mill has 2 to 5 rollers. Arrangement: vertical, roller spacing: 0 to 1mm, particle size: 5 to 60um, concentrated Adjust the pressure between the rollers to 40~60MPa at 20~30um to control the particle size; roller arc: adjust the roller arc and medium height according to the hardness of different materials, the ability of the roller to resist bending deformation, the roller pressure and the size of the feed particle size, etc. , The mid-high range is between tens of microns to a few millimeters; cooling water is turned on during grinding to prevent the roller temperature from being too high and affecting the material properties.

[0021] For the walnut grinding material after pretreatment, the oil was extracted by enzymatic method, and the oil extraction rate was 92.3%.

Abstract

The invention provides an oil plant pre-treatment method applicable to aqueous phase process oil extraction. Oil plants are pretreated by adopting an improved roller type grinding technology, and the improvement ways comprise: mutually extruding the oil plants by utilizing surfaces of multiple rollers; adjusting space between rollers and number of the rollers according to granularity required by different oil plants for extruding in different degrees; adjusting radian and medium height of each roller according to hardness of different materials, bending deformation resistance of each roller, rolling pressure and feeding grain size, wherein the medium height ranges from dozens of microns to several millimeters; guaranteeing uniform grain size in axial discharging; regulating pressure between rollers to be 10-80MPa for controlling the grain size; arranging the rollers in a vertical type (triangle shape), and atomizing the surface of each roller, so that smooth surface of each roller is changed into a rough surface; and promoting feeding, and improving capacity. The oil plant pre-treatment method applicable to the aqueous phase process oil extraction has the advantages that the problems that an oil plant pre-treatment technology is difficult and oil extraction rate is limited in an aqueous phase oil extraction technology are solved, the oil extraction rate is greatly increased and the industrialization development of the oil plant pre-treatment method applicable to the aqueous phase process oil extraction is further promoted.

Description

Technical field [0001] The invention belongs to the technical field of oil processing, and in particular relates to an oil pretreatment method suitable for water phase extraction of oil. Background technique [0002] Vegetable oil is an important source of human oil and vegetable protein. However, in the existing processing technology of oils and fats in my country, such as pressing, leaching or a combination of the two, the processing conditions are often severe, which destroys proteins and other nutrients, and reduces the utilization rate of oil resources or the economics of the processing technology. At the same time, the oil extraction process and the supporting refining process based on leaching solvents have potential safety and environmental pollution risks, and the problem of low comprehensive efficiency of resource utilization is very prominent. [0003] As a new type of oil extraction method, the aqueous phase method such as water generation method and water enzyme metho...
