Description
Technical Field
The invention belongs to the technical field of crystallization equipment, and particularly relates to a nervonic acid grease spin crystallization device and a method thereof.
Background
Nervonic acid is a core natural component of brain nerve fibers and nerve cells. The lack of nervonic acid can cause cerebral diseases such as cerebral apoplexy sequela, senile dementia, cerebral palsy, cerebral atrophy, hypomnesis, insomnia, amnesia and the like. The refined Acer Truncatum Bunge seed oil contains unsaturated fatty acids such as nervonic acid, linolenic acid, oleic acid and linoleic acid, wherein the total unsaturated fatty acids account for 98% of the total amount, and contains 5.6% of nervonic acid, 18.6% of linolenic acid, 22.8% of oleic acid and 34.3% of linoleic acid. Because the crystallization points of the fatty acids are different, the crystallization point of the nervonic acid is 42 ℃, the crystallization point of the linolenic acid is-12 ℃, the crystallization point of the oleic acid is 13.4 ℃, the crystallization point of the linoleic acid is-5 ℃, and the high-melting-point oil is crystallized into solid to be separated out by adopting a freezing crystallization mode, and then the nervonic acid and other oils are separated by adopting a filtering method. The core equipment of the extraction process is a crystallization tank. In the prior art, mechanical stirring is generally adopted to enable grease in a crystallization tank to flow and exchange heat, and the larger shearing force generated by the contact part of a paddle and the grease during rotation of the mechanical stirring can damage crystal lattices of crystals, so that the stability of the crystals in the grease crystallization process is affected, the crystals are too small, and the load of a subsequent filtering process is increased. The cooling effect at the middle part of the tank body is not obvious because the temperature near the side wall of the crystallization tank can be obviously reduced, so that the cooling is not uniform enough, and the stirring speed is required to be increased to solve the problem, but the faster the stirring speed is, the larger the generated shearing force is, and the finer and smaller the formed crystals are. How to solve the contradiction is a current urgent need to deal with.

The power device drives the transmission toothed ring to rotate, the transmission toothed ring drives the crystallization tank to spin, the bearing snap ring is used for fixing the upper and lower positions of the crystallization tank, cooling liquid is injected into a cavity formed between the crystallization tank and the cooling tank, so that the crystallization tank is cooled from the outside, and the cooling liquid is injected into the cooling coil, so that the crystallization tank is cooled from the inside, and the purposes of rapid cooling and uniform cooling are achieved. After the crystallization tank spins, the flow baffle drives grease to flow mildly in the crystallization tank, the exposed end surface of the flow baffle is an arc surface, the interference on the formed crystals is small, and the continuous growth of the crystals can be ensured. The mechanical seal moving ring is arranged below the tank cover, and the static ring is arranged above the tank cover, so that the tank cover is kept motionless, and the connection of a pipeline penetrating through the tank cover is facilitated. The material pipe outer joint is a quick joint, and is connected with the feeding pipe to serve as the feeding pipe, and is connected with the discharging pipe to serve as the discharging pipe.
Further, at least one baffle plate spirally rises from the bottom of the crystallization tank to the top of the crystallization tank.

When the crystallization tank is assembled, the crystallization tank is sleeved in the cooling tank, the neck part extends out, then the bearing snap ring is sleeved and fixed, and then the transmission gear ring is sleeved and fixed, so that the installation is completed. When discharging, the material pipe is moved upwards, clear liquid is extracted, the material pipe is gradually moved downwards, and when white crystals are observed from the sight glass, the storage tank connected with the material pipe is converted, so that the load intensity of the subsequent separation process can be effectively reduced.
Further, a temperature sensor is arranged in the crystallization tank.
Further provides a spin crystallization method of the nervonic acid grease, which comprises the following steps:
1) Injecting refined Acer truncatum seed oil into a crystallization tank through a material pipe;
2) Starting a cooling liquid circulating device, wherein the circulating speed is 500 liters/hour;
3) Starting a power device to spin the crystallization tank at a rotating speed of 10-30 rpm;
4) When the temperature in the crystallization tank is reduced to-3 ℃, controlling the temperature of the cooling liquid to keep the temperature in the crystallization tank between-3 ℃ and-4 ℃ for 1-3 hours;
5) And (3) extracting the grease with crystallization from the crystallization tank, and entering the next working procedure to finish the spin crystallization process of the nervonic acid grease.
Further, if the filter screen cylinder is not arranged, after the heat preservation in the step 5) is finished, adjusting a power device to enable the rotating speed of the crystallization tank to reach 100-120 r/min; after the highest rotating speed reaches 5-10 minutes, the material pipe is moved upwards, the pipe orifice reaches 1-2 cm below the liquid level, liquid grease starts to be pumped into the grease tank, the material pipe is moved downwards along with the liquid level, the pipe orifice of the material pipe is always kept 1-2 cm below the liquid level, and the pumping is stopped until white crystals are observed in the sight glass; closing the power device, inserting the material pipe into the bottommost part of the crystallization tank, and extracting the crystallization mixed liquid to the finished product tank to finish the spin crystallization process of the nervonic acid grease. After heat preservation is finished, the nervonic acid is fully cooled to form crystals, the rotation speed of a crystallization tank is increased, the crystals are concentrated to the wall of the tank under the action of centrifugal force, at the moment, a material pipe is inserted into the position 1-2 cm below the liquid level to start extraction, the downward moving speed of the material pipe is calculated according to the extraction flow and the volume of the tank body, the pipe orifice of the material pipe is always kept 1-2 cm below the liquid level, at the moment, liquid grease is extracted until the material pipe moves to a certain depth, crystals are extracted together with the liquid grease, and the crystals are observed by a sight glass to be converted to a finished product tank to be received. Thus, the total separation amount of the subsequent separation process can be reduced, and the workload can be reduced.
And further, if the heat preservation in the step 5) is finished when the filter screen cylinder is arranged, the power device is closed, the crystallization mixed liquid is extracted from the first material pipe to the finished product tank, the liquid grease is extracted from the second material pipe to the grease tank, the first material pipe and the second material pipe are extracted simultaneously, and the extraction speed is adjusted to ensure that the liquid level in the filter screen cylinder is always consistent with the liquid level outside the filter screen cylinder. After the filter screen cylinder is arranged, crystals are concentrated towards the tank wall under the action of centrifugal force and then carried into the filter screen cylinder by the baffle plate which rises spirally, the crystals continuously gather and grow in the filter screen cylinder, and finally most of the crystals are trapped in the filter screen cylinder. The first material pipe and the second material pipe are extracted simultaneously, and the extraction amount is calculated according to the size of the tank body and the size of the filter screen cylinder, so that the liquid level in the filter screen cylinder is always basically consistent with the liquid level outside the filter screen cylinder. Thus, the total separation amount of the subsequent separation process can be reduced, and the workload can be reduced.
