Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of algae oil DHA processing, in particular to solvent-free DHA algae oil extraction, decolorization and deodorization equipment. Background Art
[0002] DHA's important physiological functions in the central nervous system, cardiovascular system and visual nervous system have been widely recognized by society. Many countries in the world have stipulated that DHA can be used as a nutritional enhancer and food additive. At present, DHA has been used in infant food, dairy products, beverages, soy milk and edible oils, etc. The market demand is huge, so the production of DHA contains huge business opportunities.
[0003] The main sources of DHA are fish oil and algae oil. Fish oil has a strong fishy smell and high EPA content, which makes it difficult to add to food. The consumer group is also limited, and fish oil resources are limited. Large-scale, high-density culture of microalgae heterotrophic fermentation can solve the above problems. Crypthecodinium cohnii is a high-yield strain that produces DHA, and its fatty acid composition is simple, with less EPA and no fishy smell, which has a very broad application prospect.
[0004] During the extraction and refining process of algae oil DHA, some pigments, oxidation products, impurities and odors may remain. These substances will affect the quality and taste of algae oil DHA, so decolorization and deodorization treatment is required. Through decolorization treatment, the pigment substances in algae oil DHA can be removed to make its color lighter and more transparent. The deodorization treatment is to eliminate the odor and bad smell that may exist in algae oil DHA, improve its taste and quality, and in order to facilitate the subsequent decolorization and deodorization treatment after the extraction of DHA in algae oil, we proposed a solvent-free DHA algae oil extraction, decolorization and deodorization equipment.

[0023] See also Figure 1-3 A solvent-free DHA algae oil extraction, decolorization and deodorization device comprises an evaporating bottle 1, a support frame 2 for supporting the evaporating bottle 1 is placed at the bottom of the evaporating bottle 1, a heat conducting plate 3 for absorbing heat is fixedly installed at the bottom of the evaporating bottle 1, and a conical diffusion tube 4 is fixedly installed on the top of the evaporating bottle 1, and also comprises:
[0024] Adsorber 5, which is fixedly mounted on the top of the diffusion tube 4, and is used to absorb pigments and odors, thereby achieving the effect of decolorization and deodorization;
[0025] The collector 6 is fixedly mounted on the top of the adsorber 5 and is used to collect the condensed waste liquid, thereby preventing the steam from carrying impurities and falling into the evaporation flask 1 after condensation.
[0026] Furthermore, an oil guide tube 7 for guiding out the algae oil is fixedly installed on one side of the evaporating bottle 1, and an oil injection tube 8 for injecting algae oil and water is fixedly installed on the other top of the evaporating bottle 1.

[0027] Furthermore, a plurality of flame strips 9 are fixedly installed at equal intervals on the bottom of the heat conducting plate 3. The flame strips 9 can guide the diffusion of the bottom heating flame, so that the evaporating flask 1 is heated more evenly. In addition, the heat conducting plate 3 can prevent overheating caused by direct contact between the flame and the evaporating flask 1.
[0028] Furthermore, a filter 10 for permeating steam is fixedly installed on the top and bottom of the adsorber 5, and an adsorption layer 11 for adsorbing pigments and odors is fixedly installed inside the adsorber 5. The adsorption layer 11 is composed of a mixture of activated carbon and bentonite. The setting of the filter 10 facilitates the steam carrying pigments and odors to enter the adsorber 5, and then adsorb them through the adsorption layer 11, thereby achieving the effect of decolorization and deodorization. The adsorption layer 11 is composed of activated carbon and bentonite. The role of bentonite in activated carbon is to increase its pore structure and adsorption performance, and can adsorb pollutants such as organic matter and heavy metals. At the same time, it can also increase the specific surface area of activated carbon, improve its adsorption capacity and efficiency, and can effectively remove odors and pigments contained in steam, which is more practical.
[0029] Furthermore, the collector 6 includes a sleeve tube 12, a conical sleeve 13 and a collecting basket 14. The sleeve tube 12 is sleeved on the top of the adsorber 5. The conical sleeve 13 is fixedly installed on the top of the sleeve tube 12. The collecting basket 14 for collecting condensed water is fixedly installed on the bottom of the conical sleeve 13.
[0030] Furthermore, a downwardly recessed condensation groove 15 is provided at the top of the conical sleeve 13, and a plurality of diversion grooves 16 for diversion are equidistantly provided at the bottom of the conical sleeve 13. Through the arrangement of the collector 6, the sleeve pipe 12 is firstly placed as a whole on the top of the adsorber 5. After the steam enters the collector 6 through the adsorption of the adsorber 5, ice cubes can be placed in the condensation groove 15 provided at the top of the conical sleeve 13, thereby improving the condensation efficiency. After that, the steam will condense and liquefy when it contacts the conical sleeve 13, and the condensed water will fall into the collecting basket 14 along the plurality of diversion grooves 16 provided at the bottom of the conical sleeve 13, thereby preventing the liquefied condensed water from falling back into the evaporating bottle 1 and affecting the processing effect.
[0031] When in use, firstly, the algae oil to be processed is injected into the evaporating bottle 1 through the oil injection pipe 8, and then the purified water is injected, and then the oil guide pipe 7 and the oil injection pipe 8 are both sealed, and the evaporating bottle 1 can be heated as a whole through the heat conducting plate 3. The flame strips 9 are provided to guide the diffusion of the bottom heating flame, so that the evaporating bottle 1 is heated more evenly, and the heat conducting plate 3 is provided to avoid overheating caused by direct contact between the flame and the evaporating bottle 1, and then the steam carrying the pigment and the odor will enter the interior of the adsorber 5, and then it will be adsorbed by the adsorption layer 11, so as to achieve the effect of decolorization and deodorization, and the adsorption layer 11 is composed of activated carbon and bentonite as a whole. The role of bentonite in the activated carbon is to increase its pore structure and adsorption performance, and can adsorb pollutants such as organic matter and heavy metals. The steam can enter the sleeve pipe 12 and contact the bottom surface of the conical sleeve 13. The ice placed in the condensation groove 15 opened at the top of the conical sleeve 13 absorbs the heat of the steam, thereby liquefying it into water, and making it fall into the collection basket 14 along the several guide grooves 16 opened at the bottom of the conical sleeve 13, so as to avoid the condensed water after liquefaction falling into the evaporation bottle 1 again and affecting the processing effect. After the processing is completed, the oil inside can be led out through the oil guide pipe 7 to complete the processing. The new type can effectively remove the pigment and odor contained in the algae oil through the mutual cooperation between the upper structures when in use, so as to improve the taste and quality of the algae oil, and is more practical.
