In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, but the present application may be practiced in other ways other than those described herein, and persons skilled in the art will readily appreciate that the present application is not limited to the specific embodiments disclosed below.
In the following detailed description of the embodiments of the present application, reference is made to the accompanying drawings, which form a part hereof, and in which are shown by way of illustration only, and in which is shown by way of illustration only, and in which the scope of the application is not limited for ease of illustration. In addition, the three-dimensional dimensions of length, width and depth should be included in actual fabrication.
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
A first embodiment of the application provides a fish oil winterization, fractionation and crystallization reactor, as shown in fig. 1, the main body of which comprises an input assembly 100, a control assembly 200 and an output assembly 300, wherein the input assembly 100 comprises a nitrogen inlet 101, and the nitrogen inlet 101 is connected with a nitrogen replacement coil 102 inside the reactor. Nitrogen is introduced into the reaction tank through the nitrogen inlet 101, and the introduced nitrogen "replaces" the gas (e.g., oxygen) in the reaction tank, and the "replaced" gas is discharged from the gas outlet 301 of the output assembly 300 and the breather valve 400 connected thereto. Here, the meaning of "displacing" a gas is as follows: the fish oil is placed in an environment (for example, in air or a bottle tank) for a long time, oxidation occurs, and the oxygen in the environment can be replaced by introducing nitrogen into the reaction tank and discharged from the gas outlet 301. Referring to the schematic diagram of the cross-sectional view of the nitrogen-substituted coil 102 shown in fig. 2, the nitrogen-substituted coil 102 is fixed by a collar 102a and a baffle 102b, and a right-angle side of the triangular block 102c is connected to the collar 102a and a right-angle side is connected to the baffle 102b. Holes 102d are formed in the upper side and the lower side of the nitrogen replacement coil 102, nitrogen in the nitrogen replacement coil 102 is scattered into the reaction tank through the holes 102c to replace gas, so that an anaerobic environment for fish oil processing and storage is ensured, and residual volatile substances can be replaced to the outside of the tank through the gas outlet 301 and the breather valve 400 by nitrogen, thereby being beneficial to product quality. As shown in the overall structure schematic diagram of the breather valve 400 in fig. 3, the breather valve 400 comprises a valve cover 401 and a valve body 402, the valve cover 401 is covered on the valve body 402, a negative pressure valve disc 403 and a positive pressure valve disc 404 are arranged in the valve body 402, a rain nozzle 405 is arranged outside the valve body 402, the breather valve 400 uses the weights of the negative pressure valve disc 403 and the positive pressure valve disc 404 to control the positive pressure of exhaust and negative pressure of suction of a storage tank, when a medium is pumped out of the tank to enable the pressure of an upper gas space in the tank to be reduced, when the negative pressure is operated by the breather valve 400, the atmosphere outside the tank is pushed out of the negative pressure valve disc 403, external gas enters the tank, the pressure in the tank is not reduced any more, and the pressure in the tank and the pressure outside the tank are balanced, so that the safety of the storage tank is protected. When the pressure of the medium in the tank is within the control operation pressure range of the breather valve 400, the breather valve 400 does not work, and the tightness of the oil tank is maintained; when medium is replenished into the tank to raise the pressure in the upper gas space in the tank to the positive pressure for the operation of the breather valve 400, the positive pressure valve disc 404 is pushed open, and gas escapes from the outlet of the breather valve 400, so that the pressure in the tank does not increase continuously.
Preferably, the output assembly 300 of the reaction tank further comprises an overflow port 302 for recirculating excess or excess liquid back into the fish oil tank to be fractionated. Specifically, the overflow port 302 is arranged below the nitrogen inlet 101, when the liquid introduced into the reaction tank is excessive or redundant, the redundant or excessive liquid is returned to the fish oil storage tank to be separated through the overflow port 302, so that the recycling is realized, and the resource is saved.
