Description

Technical Field

[0001] The utility model belongs to the technical field of centrifugal devices, and particularly relates to a fish oil centrifugal extraction device. Background Art

[0002] Fish oil is sought after because it contains a large amount of nutrients that are beneficial to the human body. Before squeezing fish oil, the fish meat or fish fat needs to be cut into pieces or crushed and put into a cooking tank, and then an appropriate amount of water is added to the cooking tank, and the water and raw materials are heated to boiling to soften the raw materials. After squeezing the raw materials after steaming, a mixed liquid of water and fish oil can be obtained. Since fish meat or fish fat itself contains a large amount of water, adding water during the steaming process increases the water content of the raw materials after steaming, so that the mixed liquid after squeezing contains a large amount of water, so it is necessary to extract fish oil from the mixed liquid to obtain high-purity fish oil. Based on the high density of water and the low density of fish oil, it can be considered to use a centrifugal device to centrifuge the mixed liquid obtained by squeezing. When the mixed liquid is centrifuged, the water with high density will flow to the periphery of the centrifugal device, and the fish oil will be retained in the middle of the centrifugal device, but at this time, because the fish oil is in a fluid state, the fish oil cannot be effectively taken out of the centrifugal device.

[0018] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0019] See also Figures 1 to 2 The utility model provides a fish oil centrifugal extraction device, including a centrifugal cylinder 21 and a cooling device. A centrifugal stirring mechanism is arranged in the centrifugal cylinder 21. A translation mechanism is fixedly arranged above the centrifugal cylinder 21. The translation mechanism is connected with a lifting mechanism. The lifting mechanism is connected with a top cover 22 matched with the centrifugal cylinder 21. A hot air blower 15 and a hollow shaft 13 are fixedly arranged on the upper and lower surfaces of the top cover 22 respectively. A plurality of nozzles 12 are evenly spaced on the hollow shaft 13. The hot air blower 15 is connected to the hollow shaft 13. A drain cylinder 16 is fixedly connected to the lower end of the hollow shaft 13. After the top cover 22 is covered on the centrifugal cylinder 21 by the lifting mechanism, the drain cylinder 16 is located in the middle of the centrifugal cylinder 21. The cooling device is used to cool the inside of the centrifugal cylinder 21.

[0020] During centrifugal extraction, the utility model puts the mixed liquid of water and fish oil into the centrifugal cylinder 21, and the lifting mechanism drives the top cover 22 to descend, and the top cover 22 drives the drain cylinder 16 to descend into the middle of the centrifugal cylinder 21 through the hollow shaft 13, so that the top cover 22 covers the centrifugal cylinder 21, and prevents the mixed liquid from splashing out of the centrifugal cylinder 21 during centrifugation. At the same time, the top cover 22 can be used to press the centrifugal cylinder 21 on the ground to prevent the centrifugal cylinder 21 from shaking during centrifugation. The mixed liquid in the centrifugal cylinder 21 is centrifuged by the centrifugal stirring mechanism, so that the fish oil is concentrated in the middle of the centrifugal cylinder 21, and the water flows to the periphery of the centrifugal cylinder 21. The centrifugal cylinder 21 is cooled by the cooling device, and the centrifugal cylinder 21 cools the mixed liquid, so that the fish oil solidifies into blocks and is located in the drain cylinder 16 in the middle of the centrifugal device. In the cylinder 16, the water is in a fluid state and is located around the centrifugal device.

The drain cylinder 16 takes the solidified fish oil out of the centrifugal device, and the water in the drain cylinder 16 will flow out through the holes on the drain cylinder 16. Since most of the fish oil is a hydride of stearic acid, the density of most of the solidified fish oil is lower than that of water and will be retained in the centrifugal cylinder 21; when the drain cylinder 16 is raised above the centrifugal cylinder 21, the translation mechanism drives the drain cylinder 16 to translate, and after the drain cylinder 16 moves the solidified fish oil to one side of the centrifugal cylinder 21, the hot air blower 15 is started, and the hot air blower 15 conveys hot air to the hollow shaft 13. The hot air blows toward the fish oil through multiple nozzles 12, so that the fish oil is dissolved and flows out from the drain cylinder 16, which is convenient for discharge.
