Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as figure 1 Shown, the processing method of the Zanthoxylum bungeanum seed oil in the embodiment, comprises the following steps:

[0022] Step 1: crush the dried pepper seeds into granular materials; use material sorting machinery to sort out the black seed shells and white kernels in the granular materials, squeeze the kernel particles and collect them to obtain the pepper kernel hairs Oil;

[0023] Step 2: Alkali refining process: Add a mixture of ethanol-sodium hydroxide aqueous solution that is 1-2 times the weight of crude oil to the crude oil, stir at 25-60°C for 1-3h, then stand still for 1-3h, and stratification occurs. Separate the upper oil phase;

[0024] Step 3: heating the oil phase to 40°C-60°C for dehydration, then decolorizing with diatomaceous earth, filtering, and deodorizing to obtain Zanthoxylum bungeanum seed...

Abstract

The invention discloses a processing method of prickly ash seed kernel oil. The method comprises the following steps of: step 1, crushing dried prickly ash seeds into a particle material, sorting out black seed shells and white seed kernels from the particle material by adopting a material sorting machine, and squeezing seed kernel particles and collecting prickly ash seed kernel oil; step 2, adding ethyl alcohol-sodium hydroxide solution mixed liquid which is 1-2 times of the weight of crude oil into crude oil, stirring for 1-3 hours at a temperature 25-60 DEG C, then standing for 1-3 hours, layering, and separating out an oil phase on the upper layer; and step 3, heating the oil phase to 40-60 DEG C, dehydrating, then decolorizing by usingkieselguhr, filtering and deodorizing, thereby obtaining the prickly ash seed kernel oil. The processing method is capable of separating out shells and internal kernels of prickly ash seeds, respectively squeezing and soaking to obtain edible prickly ash kernel oil and prickly ash seed husk oil. The method is low in cost, high in operability and high in oil yield; the obtained prickly ash seed kernel oil is low in gelatine and waxiness contents and low in solvent residual.

Description

technical field [0001] The invention relates to the field of oil processing, in particular to a method for processing prickly ash seed oil. Background technique [0002] Zanthoxylum bungeanum seeds are the leftovers from the production of Zanthoxylum bungeanum, which is 20% more than the peel in theory, and the actual annual output is equal to that of Zanthoxylum bungeanum. In the past, people mostly used Zanthoxylum bungeanum seeds as fertilizer or discarded them, and some units also used traditional oil-making techniques to extract Zanthoxylum bungeanum oil. However, the simple processed Zanthoxylum bungeanum seed oil is tan or black, with an acid value as high as 38-65 (KOH) / (mg / g), easy to crystallize, has a pungent smell, poor taste, cannot be eaten, and can only be processed by chemical methods Into high acid value industrial oil, its price and sales are restricted. In the past, the whole seed was directly crushed and extracted to obtain the mixed oil of skin oil and...
