Abstract
Description
Technical Field
[0001] This utility model belongs to the field of diglyceride oil production technology, specifically relating to a high-efficiency and energy-saving complete set of equipment for diglyceride oil production. Background Technology
[0002] In my country, the commonly used production method for diglyceride oil involves enzymatic catalysis of triglycerides in vegetable oils followed by molecular distillation refining. For the catalytic process to occur, the vegetable oil and immobilized enzyme need to be thoroughly mixed and contacted in a reaction vessel. Currently, mechanical stirring is generally used to agitate the vegetable oil and immobilized enzyme. However, the strong shear force of mechanical stirring can easily cause the enzyme preparation to detach from the carrier or damage the structure of the enzyme carrier, reducing the utilization rate of the immobilized enzyme and significantly increasing production costs. Furthermore, the reaction rate within the reaction vessel is relatively low, and the heat energy generated during the production process is not recycled, resulting in energy waste. Therefore, overcoming these technical problems and shortcomings is a key issue that needs to be addressed. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-efficiency and energy-saving complete set of equipment for the production of diglyceride oil.
[0004] The purpose of this utility model is achieved as follows:
[0005] A high-efficiency and energy-saving complete set of equipment for the production of diglyceride oil includes a crude vegetable oil storage tank, a reaction vessel, an immobilized enzyme preparation tank, a filter, a heavy phase temporary storage tank, a crude diglyceride oil temporary storage tank, a pre-refining tank, a molecular distillation unit, a post-refining tank, and a finished diglyceride oil tank.
[0006] The outlet of the crude vegetable oil storage tank is connected to the vegetable oil inlet pipe at the top of the reactor, and the outlet of the immobilized enzyme preparation tank is connected to the enzyme injection port at the top of the reactor.
[0007] The reactor is equipped with an internal heating mechanism and an internal cooling mechanism in the middle. The internal cooling mechanism is located inside the internal heating mechanism. The lower part of the reactor has a conical structure. A pneumatic stirring mechanism is installed in the lower part of the reactor. The heavy phase outlet at the bottom of the reactor is connected to the inlet pipe of the heavy phase storage tank. The light phase outlet at the bottom of the reactor is connected to the inlet pipe of the filter. The filtrate outlet of the filter is connected to the inlet pipe of the crude glycerol oil storage tank. The filter cake outlet of the filter is connected to the immobilized enzyme preparation tank.
[0008] The discharge port of the crude glycerol oil storage tank is connected to the crude oil inlet pipe at the top of the refining tank. The refining tank is equipped with a heat exchange mechanism. The crude oil outlet at the bottom of the refining tank is connected to the feed inlet pipe of the molecular distillation unit.
[0009] The discharge port of the molecular distillation unit is connected to the inlet pipe of the refined post tank, the discharge port of the refined post tank is connected to the hot diglyceride oil inlet pipe of the refined pre tank, and the diglyceride oil outlet of the refined pre tank is connected to the inlet pipe of the diglyceride oil finished product tank.
[0010] Furthermore, the internal heating mechanism includes an internal heating coil fixed in the middle of the reactor. The upper end of the internal heating coil is connected to the steam heating inlet of the internal heating coil, and the lower end of the internal heating coil is connected to the drainage mechanism of the internal heating coil. The material in the reactor can be heated by the heating steam in the internal heating coil, which can improve the reaction rate.
[0011] Furthermore, the internal cooling mechanism includes an internal cooling coil fixed in the middle of the reactor. The internal cooling coil is located inside the internal heating coil. The lower end of the internal cooling coil is connected to the cooling water inlet, and the upper end of the internal cooling coil is connected to the cooling water outlet. After the material in the reactor has reacted completely, the material is cooled by the cooling water in the internal cooling coil, so that the material in the reactor remains still and stratifies.
[0012] Furthermore, a jacket is fitted around the middle of the outer side of the reactor. A jacket heating inlet is provided on the upper left side of the jacket, and the lower right side of the jacket is connected to the jacket drainage mechanism through a pipe. The heating steam inside the jacket is used to heat and keep the material inside the reactor warm, which can further improve the reaction rate.
[0013] Furthermore, the pneumatic stirring mechanism includes a pneumatic stirring coil laid in the lower part of the reactor. The inlet of the pneumatic stirring coil is connected to a gas inlet, which is connected to a nitrogen pipeline. The lower end of the wall of the pneumatic stirring coil is provided with a diamond-shaped gas outlet, which allows for efficient pneumatic stirring of the materials in the reactor using nitrogen.
[0014] Furthermore, the top of the reactor is provided with a vacuum port and an air vent.
[0015] Furthermore, the heat exchange mechanism includes a heat exchange coil. The lower end of the heat exchange coil is connected to the hot diglyceride oil inlet, and the upper end of the heat exchange coil is connected to the diglyceride oil outlet. The high-temperature diglyceride oil in the refined tank enters the heat exchange coil and exchanges heat with the crude diglyceride oil that needs to be refined in the pre-refining tank, which can save energy.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. The reactor of this utility model is equipped with an internal heating coil and an internal cooling coil in the middle of the interior, and a jacket is fitted on the middle of the outer side of the reactor. The heating steam in the internal heating coil heats the material in the reactor, and the heating steam in the jacket further heats and keeps the material in the reactor warm, which can effectively improve the reaction rate. After the material has reacted completely, the cooling water in the internal cooling coil cools the material, so that the material in the reactor settles and separates into layers, which facilitates the subsequent processing steps.
[0018] 2. The lower part of the reaction vessel of this utility model is equipped with a pneumatic stirring coil. Nitrogen gas is introduced into the pneumatic stirring coil to efficiently stir the materials in the reaction vessel. The diamond-shaped air outlet at the lower end of the pneumatic stirring coil allows the nitrogen gas to form irregular bubbles in the materials, achieving bottom-up turbulence of the materials. This ensures that the immobilized enzymes and vegetable oils in the materials are fully and efficiently mixed. Since non-powered pneumatic stirring is used, the shear force of mechanical stirring is avoided from damaging the immobilized enzymes, allowing the immobilized enzymes to be reused. Therefore, while achieving efficient mixing between materials, the service life of the immobilized enzymes can be extended, which can significantly save production costs.
[0019] 3. The pre-refining tank of this utility model is equipped with a heat exchange coil. The high-temperature diglyceride oil in the post-refining tank enters the heat exchange coil and exchanges heat with the crude diglyceride oil to be refined in the pre-refining tank. The finished diglyceride oil, cooled by heat exchange, enters the finished diglyceride oil tank for storage. The crude diglyceride oil, heated by heat exchange, enters the molecular distillation unit for distillation and refining. Through heat exchange, the heat energy can be reused, achieving the effect of energy saving. Attached Figure Description

[0042] The working principle of this utility model is as follows:
[0043] First, the vegetable oil in the crude vegetable oil storage tank 1 and the immobilized enzyme in the immobilized enzyme preparation tank 3 are added to the reaction vessel 2. Nitrogen gas is introduced into the pneumatic stirring coil 209. The nitrogen gas forms irregular bubbles in the material, which agitates the material from bottom to top, so that the immobilized enzyme and vegetable oil in the material are fully and efficiently mixed. Heating steam is introduced into the internal heating coil 217 and the jacket 215 to heat the material in the reaction vessel 2, increase the reaction rate, and generate crude diglyceride oil through catalytic reaction.
[0044] Then, after the material in the reactor 2 has reacted completely, cooling water is introduced into the internal cooling coil 206 to cool the material in the reactor 2. After cooling, the material settles and separates into layers. The heavy phase enters the heavy phase storage tank 4 through the heavy phase outlet 211 for temporary storage, and the light phase enters the filter 5 through the light phase outlet 212.
[0045] Then, filter 5 filters the immobilized enzyme in the light phase. The filtered immobilized enzyme enters the immobilized enzyme preparation tank 3 through the filter cake outlet for recycling. The filtered filtrate enters the crude glycerol oil temporary storage tank 6 through the filtrate outlet for storage.
[0046] Subsequently, the crude diglyceride oil enters the pre-refining tank 7 through the crude oil inlet 705. The pre-refining tank 7 temporarily buffers the crude diglyceride oil. The crude diglyceride oil then enters the molecular distillation unit 8 through the crude oil outlet 703 for molecular distillation refining. The distilled diglyceride oil is at a high temperature, and the hot diglyceride oil enters the post-refining tank 9 for buffering and temporary storage.
[0047] Finally, the buffered hot diglyceride oil enters the heat exchange coil 701 in the refining tank 7 through the hot diglyceride oil inlet 702, where it exchanges heat with the crude oil in the refining tank 7, preheating the crude oil. The preheated crude oil then enters the molecular distillation unit 8, and the finished diglyceride oil after heat exchange is stored in the finished diglyceride oil tank 10. This allows for the secondary utilization of heat energy, saving energy and reducing production costs.
