Description

Technical Field

[0001] The invention relates to the technical field of extracting linolenic acid from hemp seeds, in particular to a preparation process and a method for extracting linolenic acid from hemp seeds. Background Art

[0002] Linolenic acid is a polyunsaturated fatty acid that belongs to the ω-3 series of fatty acids. Linolenic acid is one of the essential fatty acids for the human body, but the human body cannot synthesize it and must be obtained from food. Hemp seeds are a natural source of linolenic acid.

[0003] Patent number CN 218306295 U is a kind of ultrasonic extraction equipment for preparing ganoderma lucidum polysaccharide, belonging to the technical field of beauty cosmetics production equipment. The equipment includes a box, an isolation screen, a water spray pipe, a pressure pump and an ultrasonic extractor. When adding ganoderma lucidum powder and water for ultrasonic extraction, the pressure pump is started, and the ganoderma lucidum powder on the isolation screen is sprayed with normal temperature or low temperature water through the water spray pipe, so that the ganoderma lucidum powder accumulated at the bottom moves upward. After multiple spraying, the negative effect of ganoderma lucidum powder accumulation on ultrasonic extraction can be reduced. At the same time, the spraying of normal temperature water or low temperature water can reduce the degradation effect of ganoderma lucidum polysaccharide caused by the thermal effect of ultrasonic extraction. The extraction equipment solves the problem of insufficient extraction.

[0004] Although the above invention patent solves the problem of insufficient extraction, the patent does not have the function of cleaning the hemp seed particles on the filter plate after extracting linolenic acid, does not have the function of facilitating the removal of the filter plate for cleaning, and does not have the function of recycling the hemp seed particles for re-extraction. During use, if the hemp seed waste after extraction cannot be cleaned out in time, manual cleaning will be more troublesome, which will affect the preparation equipment from continuing to extract the next batch of linolenic acid, making the work efficiency of the preparation equipment poor. If it is not convenient to remove the filter plate for cleaning, it may require professionals to disassemble it. The convenience of the equipment is poor. When the linolenic acid in the hemp seed is soaked and extracted, the linolenic acid in the hemp seed may not be fully extracted. If the extraction cannot be cyclically extracted, the linolenic acid in the hemp seed cannot be completely extracted, resulting in low yield and waste of resources. The use effect of the equipment is poor, and it does not have the function of fully mixing the hemp seed particles and the extract. During use, if the extract and the hemp seed particles cannot be stirred, the hemp seed particles and the extract will be unevenly contacted, and the linolenic acid cannot be effectively dissolved from the hemp seed, thereby reducing the extraction efficiency and yield.

The preparation equipment for extracting linolenic acid from seed of hemp according to claim 1, characterized in that: The stirring mechanism (3) comprises a second motor support (301), the top of the extraction tank (1) is fixedly connected to the second motor support (301), the inner side of the second motor support (301) is fixedly connected to a second motor (302), the output shaft of the second motor (302) is fixedly connected to a second motor shaft (303) via a coupling, and the outer wall of the second motor shaft (303) is fixedly connected to a stirring blade (304).

8. The method for preparing the equipment for extracting linolenic acid from hemp seeds according to any one of claims 1 to 7, characterized in that: The following steps are involved: Step S1, opening the cover plate (4) through the second handle (5), then adding the crushed hemp seed particles and water into the extraction tank (1), the hemp seed particles will fall onto the filter plate (6), and then the hemp seed particles and the extract need to be stirred so that the linolenic acid in the hemp seed can be more effectively dissolved in the extract; Step S2, starting the second motor (302), causing the second motor (302) to start rotating, the second motor (302) driving the second motor shaft (303) to start rotating, the second motor shaft (303) driving the stirring blade (304) to start rotating, so that the stirring blade (304) stirs the hemp seed particles and the water, thereby completing the stirring work; Step S3, during stirring, the extraction tank (1) will vibrate. During the vibration, the damping plate (17) moves in the chute (15) through the action of the damping spring (16), thereby damping the extraction tank (1), and the linolenic acid in the hemp seed particles is dissolved into the water through stirring; Step S4, starting the water pump (8), the water pump (8) discharges the water containing linolenic acid into the extraction box (9) through the water extraction pipe (7), when the water is drained, the hemp seed particles can be blocked on the filter plate (6) by filtering through the filter plate (6), at this time, the hemp seed particles need to be cyclically extracted to extract the linolenic acid in the hemp seed, and the hemp seed particles are rolled to the side with the extraction pipe (211) by tilting the filter plate (6); Step S5, starting the first motor (206), so that the first motor (206) starts to rotate, the first motor (206) drives the first motor shaft (207) to start rotating, the first motor shaft (207) drives the gear (208) to start rotating, the gear (208) drives the gear (208) to start moving through the rack (202) on the fixed block (201), the gear (208) drives the connecting rod (209) to start moving, the connecting rod (209) drives the push plate (210) to start moving, the push plate (210) slides on the slide rail (204) through the first motor bracket (205), so that the push plate (210) can move more steadily and smoothly, so that the push plate (210) pushes the hemp seed particles on the filter plate (6) to the extraction pipe (211); Step S6, starting the pump body (212), the pump body (212) extracts the hemp seeds on the filter plate (6) through the extraction pipe (211), and then discharges them into the extraction tank (1) again through the extraction pipe (211); Step S7, adding water in a good proportion, stirring through the stirring mechanism (3), performing cyclic extraction on the hemp seed, and also discharging the obtained mixed solution into the extraction box (9) through the water extraction pipe (7), thereby completing the cyclic extraction work; Step S8, separating water from linolenic acid by extraction in an extraction box (9) to obtain linolenic acid; Step S9, start the extraction pump (11), and the extraction pump (11) discharges the linolenic acid in the extraction box (9) through the discharge pipe (10), thereby completing the preparation work.
