preparation example Construction

[0030] A preparation method of dried Zanthoxylum bungeanum oil of the present invention adopts mass transfer extraction of particle interface material, grinds dried Zanthoxylum bungeanum raw material to D98=10-100 μm powder and mixes it with vegetable oil, and then applies 300,000-400,000 times / min to Zanthoxylum bungeanum powder and vegetable oil The shearing and extrusion force, followed by solid-liquid separation to obtain the finished Zanthoxylum bungeanum oil.

[0031] The principle of particle interface mass transfer extraction: the smaller the particle, the larger the surface area, and the greater the surface energy, the particle interface will adsorb molecular substances to form a stable structure. At this time, strong mechanical energy is used to break through the gap barrier between particles and molecular substances. Its substance moves from the particle interface to the solvent.

[0032] see figure 1 , the above method specifically includes the following steps:

...

Embodiment 1

[0045] Step 1, take 1kg of dried Zanthoxylum bungeanum, pulverize to the Zanthoxylum bungeanum powder that average particle size is D98=80 μm;

[0046] Step 2, adding Chinese prickly ash powder and 8 kg of vegetable oil preheated to 30°C or 100°C into a vibrating refiner (stick type);

[0047] Step 3, in a fully enclosed environment and under the protection of nitrogen, apply 300,000 times / minute shearing and squeezing force to the pepper powder and vegetable oil for extraction, which lasts for 26 minutes;

[0048] In step 4, the extracted Zanthoxylum bungeanum powder and vegetable oil are subjected to 2-3 phase solid-liquid separation by using a solid-liquid separator to obtain finished Zanthoxylum bungeanum oil and separation slag, wherein the separation slag is used for making carbon rods.

Embodiment 2

[0050] Step 1, take 1kg of dried Zanthoxylum bungeanum, pulverize to the Zanthoxylum bungeanum powder that average particle size is D98=50 μ m;

[0051] Step 2, add the Chinese prickly ash powder and 15kg of vegetable oil preheated to 40°C or 130°C into the vibrating refiner (stick type);

[0052] Step 3, in a fully enclosed environment and under the protection of argon, apply 350,000 times / minute shearing and squeezing force to the pepper powder and vegetable oil for extraction, which lasts for 18 minutes;

[0053] In step 4, the extracted Zanthoxylum bungeanum powder and the vegetable oil are subjected to 2-3 phase solid-liquid separation by using a solid-liquid separator to obtain the finished Zanthoxylum bungeanum oil and the separation slag, wherein the separation slag is used for papermaking.

Abstract

The invention discloses a preparation method of dry pricklyash peel oil. The preparation method comprises the steps of conducting mass-transfer extraction on particle interface materials, pulverizing dry pricklyash peel raw materials into powder with the diameter D98 ranging from 10 micrometers to 100 micrometers, mixing the power with plant oil, then applying shearing and extrusion force to the pricklyash peel powder and the plant oil with the frequency being 300-400 thousand cycles / minute, and then conducting solid-liquid separation, so that the finished pricklyash peel oil is obtained. By means of the preparation method of the dry pricklyash peel oil, the problem of oil oxidation caused by the oil temperature ranging from 140 DEG C to 180 DEG C in the traditional process is solved; the situation that cancerogen such as superoxide and dimer is generated due to the high temperature of the traditional extraction process is avoided; the dry pricklyash peel raw materials are pulverized into the power with the diameter D98 ranging from 10 micrometers to 100 micrometers, then extraction is conducted, stewed pricklyash peel is not generated, and the problem that stewed pricklyash peel is difficult to treat is solved; separation residues can be recycled, the environment cannot be polluted, and the extraction rate is high.

Description

technical field [0001] The application belongs to the technical field of condiment processing, in particular, it relates to a preparation method of dried prickly ash oil. Background technique [0002] Traditional pepper oil extraction methods include frying, ultrasonic extraction, and supercritical CO2 extraction. [0003] The frying method is as follows: put the pepper directly into the hot edible vegetable oil, cover and seal it, or put the pepper into a container, the oil outlet hole diameter of the container is smaller than the diameter of the pepper, and slowly pour the edible vegetable oil at 140-180°C into the container In the middle of frying, the fragrance is released, and the active ingredients are dissolved in the oil, and the pepper oil is obtained. Its disadvantages are: (1) The oil temperature is not easy to control. If the temperature is too high, the aroma and numbness components in the pepper are easily volatilized and decomposed and lost; (2) The active i...
