Description

Technical Field

[0001] The invention relates to the field of food processing, and in particular to a preparation method of hemp seed oil microcapsule powder and application thereof. Background Art

[0002] Hemp seed oil microcapsule powder refers to a microencapsulated powder product made from hemp seed oil (i.e. hemp seed oil). This product is usually made by encapsulating hemp seed oil in tiny vesicles (microcapsules) through microencapsulation technology, and then making it into powder form to increase its stability and ease of use.

[0003] Specifically, the characteristics of hemp seed oil microencapsulated powder may include:

[0004] Microencapsulation technology: Microencapsulation is a technology that encapsulates liquid or solid active ingredients in tiny vesicles. For hemp seed oil microencapsulation powder, this technology can effectively protect the nutrients in the oil from external factors such as oxidation, light or heat, and extend its stability and shelf life.

[0005] Easy to carry and store: The microencapsulated powder form makes hemp seed oil easier to carry and store, which is more convenient than the liquid form, and is especially suitable for use during travel or daily life.

[0006] Nutrient retention: Microencapsulation technology can retain the nutrients in hemp seed oil, such as rich Omega-3, Omega-6 fatty acids, vitamins and antioxidants, thereby ensuring that its nutritional value is not lost during the preparation process.

[0007] The production of hemp seed oil microcapsule powder requires multiple steps. The main materials are hemp seed oil and wall materials. The raw material of hemp seed oil is hemp seed. Hemp seed needs to go through multiple procedures to be prepared into hemp seed oil. Among them, cleaning and drying is a very important step, which directly affects the quality of hemp seed oil.

[0008] In the traditional hemp seed drying process, in order to save costs, the sun is directly used. However, this method will cause the dried hemp seeds to contain a large amount of impurities, which need to be further cleaned. When mechanical equipment is used for cleaning, most of the hemp seeds will be placed directly in the drying box to form a pile. This will cause the hemp seeds on the outside and inside to dry at different speeds, and it is also impossible to clean the impurities contained in the hemp seeds, and a separate cleaning process needs to be carried out later. Summary of the invention

The present invention uses an exhaust fan, which can continuously exhaust air through the first filter cover and the second filter cover, so that suction can be generated, thereby adsorbing impurities in the fallen hemp seeds, and accelerating the flow of air can accelerate the drying of the hemp seeds. Hot air can also be introduced for drying, and impurities will enter the first filter cover instead of passing through the second filter cover, so that impurities can be effectively collected. Due to the effect of wind force, the first auger and the second auger can be operated to transport the hemp seeds, so that the hemp seeds can be circulated and dried. After each circulated transportation of the hemp seeds, they will fall in a dispersed manner, which is not only more conducive to drying, but also better for collecting impurities therein.

In this way, the cleaning ring can effectively clean the through holes on the inner wall of the second auger during the operation of the second auger to avoid blockage.

[0038] 3. By adjusting the direction of the exhaust fan, the exhaust fan can draw wind in different directions, so that the exhaust fan can drive the first drive box to rotate, the first drive box can rotate the first reciprocating screw, and the first reciprocating screw will drive the cleaning ring to move up and down, thereby effectively cleaning the surface of the first filter cover to avoid clogging and affecting its use.

[0039] 4. By setting the rotating plate, the descending speed of the hemp seeds can be slowed down, so that they can be dried more fully. The second driving box operated by the wind power of the exhaust fan can effectively drive the sliding frame to move up and down. The sliding frame moves up and down, which can act on the rotating plate, so that the rotating plate can be tilted and instantly flipped upward, so that the falling hemp seeds can be effectively thrown out, which not only increases the residence time of the hemp seeds, but also makes the piles of hemp seeds scattered, which can be better mixed and dried.
