Description

Technical Field

[0001] The utility model relates to the technical field of extraction, in particular to a device for extracting perilla seed oil based on a water-enzyme method. Background Art

[0002] Perilla is a traditional oil crop in my country. The dried and mature fruit of perilla is called perilla seed, which is rich in perilla seed oil. At the same time, perilla leaves also contain a large number of oil cells, which can be used as raw materials for oil extraction. Perilla seed oil has the effects of preventing cardiovascular diseases, anti-oxidation, inhibiting cancer cell proliferation, improving cognition and memory, anti-bacterial and anti-inflammatory, anti-allergic, preventing and treating non-alcoholic fatty liver, and affecting bone metabolism. It is one of the vegetable oils with the highest α-linolenic acid content found in seed oils. It has huge market development potential in the food, medicine and other industries. With the continuous advancement and development of the big health industry, perilla seed oil series products are gradually penetrating into our lives.

[0003] At present, the water-enzyme method is basically used to extract perilla seed oil on the market. The water-enzyme method mainly uses enzymes (protease, amylase, pectinase, vitamin enzyme, etc.) to degrade plant cell walls to release oil based on mechanical crushing. As an emerging "green and environmentally friendly" oil extraction technology, it can efficiently recover other valuable components in oil while extracting oil. It is called "a full utilization technology of oil resources" by the oil science community. However, when the existing oil-water enzyme treatment device extracts oil, it is difficult to continuously provide an extraction environment with suitable temperature and pressure due to the lack of temperature and pressure control devices. The enzyme cannot play its role to the maximum extent, which is not conducive to the rapid production of perilla seed oil. In addition, the existing equipment simply relies on stirring to mix the raw materials, which is difficult to further improve the oil yield, and nutrients are not easy to seep out, affecting the yield and quality of perilla seed oil.

The bottom of the reaction tank 1 is provided with a first discharge port 11, the lower end of the oil-residue separation system 7 is provided with a second discharge port 74, and the centrifuge 9 is provided with a third discharge port 91. During the process of extracting perilla seed oil, the material can flow from the first discharge port 11, the second discharge port 74 and the third discharge port 91 in sequence, and finally flow to the oil storage tank 8. An upper cover 12 is provided above the reaction tank 1, and an ultrasonic rod 2 is provided in the middle of the upper cover 12 and toward the reaction tank 1. A temperature sensor (not shown in the figure) and a pressure sensor (not shown in the figure) are also provided in the reaction tank 1. The control system 3 and The ultrasonic rod 2, the temperature sensor and the pressure sensor are connected to control the ultrasonic frequency, temperature and pressure in the reaction tank 1. Specifically, the temperature in the reaction tank 1 can be set to 55°C. The oil-residue separation system 7 includes a separation tank 71, which is arranged below the reaction tank 1 and communicated with the first discharge port 11. The separation tank 71 is provided with a first filter plate 72 and a second filter plate 73. The first filter plate 72 and the second filter plate 73 form a "<" shape. The first filter plate 72 is provided with a plurality of through holes (not shown in the figure), the lowest point of which is connected to the discharge port 75 of the separation tank 71, and the lowest point of the second filter plate 73 is connected to the second discharge port 74. The device maintains an environment more suitable for the perilla seed oil and nutrients to seep out. The ultrasonic frequency, temperature and pressure in the reaction tank 1 can be adjusted as the extraction proceeds, and the residue generated during the extraction process can be discharged freely. The extracted perilla seed oil flows toward the second discharge port 74 along the second filter plate 73, without the need for manual slag discharge, and can effectively reduce mechanical impurities in the oil. Specifically, the first filter plate 72 may be inclined at 10° to the bottom surface of the reaction tank 1 , and the second filter plate 73 may be inclined at 170° to the bottom surface of the separation tank 71 .

[0029] Specifically, the side wall and the bottom of the reaction tank 1 are provided with a jacket 4. Specifically, the heating jacket provides heat to the reaction tank 1. The control system 3 adjusts the temperature of the jacket 4 according to the feedback of the temperature sensor, so that the reaction tank 1 maintains a temperature suitable for the perilla seed oil and nutrients to seep out, thereby increasing the extraction amount of the perilla seed oil.

[0030] Specifically, the reaction tank 1 includes a straight tank body 13 and a conical tank body 14, the conical tank body 14 is arranged below the straight tank body 13, and the first discharge port 11 is arranged at the bottom of the conical tank body 14. The lower part of the reaction tank 1 is arranged as the conical tank body 14, so that the residue generated during the extraction process enters the first discharge port 11 more smoothly, avoiding the residue being left in the reaction tank 1 and affecting the quality of the perilla seed oil.

[0031] Specifically, the control system 3 is arranged at or away from the straight tank body 13.

Perilla seed oil will float on the surface of the non-oil substance. Therefore, the fourth discharge port 92 is provided below the third discharge port 91, and the non-oil substance enters the liquid storage tank through the fourth discharge port 92. The non-oil substance can be used for other purposes to avoid pollution and waste.

[0035] The oil storage tank 8 and the liquid storage tank 11 are provided with a visual window 81 and a scale line 82 to observe the storage situation and avoid overflow.

[0036] The working principle of the above equipment is as follows: the preliminarily crushed perilla seeds are added into the reaction tank 1 through the feed port 6 of the upper cover 12, and the aqueous enzyme extract is added into the reaction tank 1 from the automatic liquid feeder 5. The temperature and pressure in the reaction tank 1 are controlled by the control system 3. The perilla seeds and the aqueous enzyme extract are evenly mixed through the cavitation effect of the ultrasonic rod 2. The extraction time can be 3.5 hours. During the extraction process, the residue is discharged into the fermentation tank 10 along with the first filter plate 72, and the oil flows from the through hole of the first filter plate 72 to the second filter plate 73, and flows into the centrifuge 9 through the second discharge port 74. The separation of oil and non-oil components is completed in the centrifuge 9. Finally, the perilla seed oil is collected into the oil storage tank 8, and the non-oil components are collected into the liquid storage tank 11.
