Problems solved by technology

However, because the shell content of passionflower seeds is as high as 60%, the shell is hard, and the shell and kernel are tightly combined together, so it cannot be shelled
As a result, the pressure in the press chamber of the 95-type oil press machine was too high, and the load increased, so that the oil could not be pressed

Embodiment 1

[0015] (1) Wash 100kg of fresh fruit seeds, dry them naturally until the water content is 8%, and obtain 75kg of dried fruit seeds

[0016] (2) Dried passionflower seeds are crushed to 5-10 mesh, weigh 8kg of material and put it into a cloth bag, put it into the barrel of the cylinder type rapid hydraulic oil press, close the movable top, and start pressing.

[0017] (3) When the pressure reaches 15MPa, the oil starts to flow out, and when the oil reaches 50MPa, the oil can be completely discharged, and the load can be unloaded. After the pressure gauge returns to 0, pull the movable top, put the manual valve at the rising position, and the piston will rise to push the top of the cake Out of the barrel.

[0018] (4) After the cake is released, place the manual valve in the down position, the piston will go down to the bottom when you hear the sound of the overflow valve, and then it will fall to the bottom, place the manual valve in the middle position, reload, pressurize, oil...

Embodiment 2

[0021] (1) 100kg of fresh fruit seeds are washed, and naturally air-dried to a moisture content of 9%, to obtain 78kg of dried fruit seeds.

[0022] (2) Dried passionflower seeds are crushed to 5-10 mesh, weigh 8kg of material and put it into a cloth bag, put it into the barrel of the cylinder type rapid hydraulic oil press, close the movable top, and start pressing.

[0023] (3) When the pressure reaches 16MPa, the oil starts to come out, and when it reaches 50MPa, the oil comes out completely, and the load can be unloaded. After the pressure gauge returns to 0, pull the movable top, put the manual valve in the rising position, and the piston will rise to top the cake. Out of the barrel.

[0024] (4) After the cake is released, place the manual valve in the down position, the piston will go down to the bottom when you hear the sound of the overflow valve, and then it will fall to the bottom, place the manual valve in the middle position, reload, pressurize, oil out, and mater...

Embodiment 3

[0027] (1) Wash 100kg of fresh fruit seeds, dry them naturally until the water content is 7%, and obtain 72kg of dried fruit seeds

[0028] (2) Dried passionflower seeds are crushed to 5-10 meshes, weighed 8kg and put them into a cloth bag, and then put them into the cylinder of a cylinder-type rapid hydraulic oil press, close the movable top, and start pressing.

[0029] (3) When the pressure reaches 15.5MPa, the oil starts to flow out, and when the oil reaches 50MPa, the oil can be unloaded. After the pressure gauge returns to 0, pull the movable upper top, put the manual valve at the rising position, and the piston rises to release the cake. Eject the barrel.

[0030] (4) After the cake is released, place the manual valve in the down position, and the piston will go down to the bottom when you hear the sound of the overflow valve, and then it will fall to the bottom. Place the manual valve in the middle position, reload, pressurize, oil out, and material out, complete Oil ...

Abstract

The invention relates to a method and a process for extracting passionflower seed oil by a cold pressing process. The method comprises the following main processes: naturally airing passionflower seeds till the water content is 7 to 10 percent, crushing the passionflower seeds to 5 to 10 meshes, charging 6 to 9 kilograms of crushed passionflower seeds into a cloth bag, feeding the cloth bag into a cylindrical quick hydraulic oil press charging barrel, and pressing the passionflower seeds under the pressure of 15 to 50MPa to obtain cold pressed crude oil and oil cakes respectively, wherein the oil yield is 13 to 18 percent. The method has the advantages of simple process flow, easy operation and environmental protection; the pressing is performed at normal temperature by selecting the cold pressing method so that thermosensitive substances in the oil are not destroyed and the nutritional components therein are integrally kept; and the passionflower seed oil for medicinal and food use is obtained by further low-temperature refining.

Description

Technical field: [0001] The invention relates to a method and a process for extracting passion flower seed oil by adopting a cold pressing process. Background technique: [0002] Passiflora is a perennial evergreen vine of the Passiflora family Passiflora, and its fruit is a typical tropical and subtropical berry. Passion fruit is rich in nutrition, contains a lot of vitamins and minerals, and also contains sugars and 17 kinds of amino acids. Passion fruit juice has a unique fragrance, a mellow taste, and is rich in various nutrients, so it is an ideal high-end beverage. [0003] Passiflora fruit contains 34% fruit juice, 55% peel and 11% seeds, and 21%-25% oil in the seeds. The fatty acid composition of passionflower seed oil is mainly unsaturated fat linoleic acid and oleic acid. The content of unsaturated fatty acid is more than 80%, especially the essential fatty acid of human body—the content of linoleic acid is as high as more than 72%. Linoleic acid is the main comp...
