Embodiment 1

[0024] (1) Drying: Take 500kg of Jingzhou pecans and spread them on the mesh platform in the drying room. Slightly cracked, dried to a moisture content of 15%;

[0025] (2) Crushing: Use a crusher to crush the pecans, and then use a stainless steel screen to separate the larger walnut shells from the walnut kernels, and keep 15% of the smaller walnut shells in the walnut kernels;

[0026] (3) Steaming: put the separated walnut kernel and walnut shell mixed oil into a wooden steamer, the oil accounts for 75% of the whole mixture, and steam the walnut mixture for 8 minutes with atmospheric pressure steam, so that the moisture content of the oil is 12% ;

[0027] (4) Pressing: Use the oil bag of the hydraulic oil press to bag the steamed oil, drop the hydraulic column of the hydraulic oil press to the lowest position, and put the bagged oil into the press chamber of the hydraulic oil press In the process, close the safety cover, tighten the fixing screws, set the pressure of th...

Embodiment 2

[0039] The difference with embodiment 1 is:

[0040] (1) Drying: Take 1000kg of Jingzhou pecans and spread them on the mesh platform in the drying room. Slightly cracked, dried to a moisture content of 12%;

[0041] (2) Crushing: Use a crusher to crush the pecans, and then use a stainless steel screen to separate the larger walnut shells from the walnut kernels, and keep 18% of the smaller walnut shells in the walnut kernels;

[0042] (3) Steaming: put the separated walnut kernel and walnut shell mixed oil into a wooden steamer, the oil accounts for 80% of the whole mixture, steam the walnut mixture for 10 minutes with atmospheric pressure steam, so that the moisture content of the oil is 15% ;

[0043] (4) Pressing: Use the oil bag of the hydraulic oil press to bag the steamed oil, drop the hydraulic column of the hydraulic oil press to the lowest position, and put the bagged oil into the press chamber of the hydraulic oil press In the process, close the safety cover, tigh...

Abstract

The invention discloses a method for squeezing pecan oil. The method comprises the following steps: drying pecan till water content is 10-15%; using a crusher for crushing pecan, and then using a stainless steel screen for separating bigger pecan shells from pecan kernels, and reserving 15%-20% of smaller pecan shells in the pecan kernels; putting the mixed oil material of separated pecan kernelsand pecan shell into a wooden steamer, and utilizing vapor under normal pressure to steam the pecan mixture for 8-12 minutes till the water content of oil material is 12-18%; bagging the steamed oil material into an oil bag of a hydraulic oil press, putting the bagged oil material into a barrel of the hydraulic oil press, closing a safety cover, fastening a fixing screw and starting the machine for squeezing, thereby acquiring primary squeezed oil; refining the primary squeezed oil, thereby acquiring the refined pecan oil. The method disclosed by the invention has the advantages of high oil yield, high oil quality and less damage to nutrition.

Description

technical field [0001] The invention relates to hickory oil, in particular to a method for pressing hickory oil. Background technique [0002] Jingzhou is a national pecan cultivation and comprehensive processing demonstration area and a national pecan ecological origin protection demonstration area. As one of the "Three Treasures of Jingzhou" (red bayberry, poria cocos, and pecan), pecan has a history of more than 300 years. It is famous all over the country for its good benevolence, crisp texture, fragrance, heavy oil and delicious taste. It is known as the "Southern Hickory City"; the hickory nuts in Jingzhou County have good taste and affordable prices. Quality, it is the first choice for oil extraction, making cakes, and candies. It is not only delicious, but also has high nutritional value. At the same time, it is rich in natural VA, VD and other nutrients. The pecan oil sold on the market is known as oriental olive oil by the international market; the fatty acid cont...
