Description

Technical Field

[0001] This invention relates to the field of vegetable oil processing technology, specifically to an apparatus and process for enzymatic degumming of vegetable oil. Background Technology

[0002] The gums in vegetable oils are mainly phospholipids. In the refining and processing of vegetable oils, phospholipids are an impurity that needs to be removed. Before the oil is decolorized, the phosphorus content is generally required to be below 30 mg / kg, preferably below 10 mg / kg. The process of removing phospholipids is usually called "degumming".

[0003] Existing enzymatic degumming methods for vegetable oils typically involve mixing an enzyme-containing aqueous solution with vegetable oil, followed by sedimentation and degumming after stirring and mixing.

[0004] However, in the process of adding the enzyme-containing aqueous solution to vegetable oil, the phospholipase and water need to be mixed in the outside environment first to obtain the enzyme-containing aqueous solution. When the enzyme-containing aqueous solution is injected into the vegetable oil through the pipeline, the enzyme-containing aqueous solution is prone to local high concentration. Therefore, a long stirring and mixing time is required to ensure that the enzyme-containing aqueous solution is fully mixed with the vegetable oil. Therefore, we propose an enzymatic degumming device and process for vegetable oil. Summary of the Invention

[0026] A process for enzymatic degumming of vegetable oils, the process comprising the following steps:

[0027] Step 1: First, add untreated vegetable oil into the degumming tank through the oil inlet, and at the same time add water and phospholipase into the enzymatic tank through the feed inlet;

[0028] Step 2: The medium flowing into the inlet pipe is heated by an external heat source. After heating, the medium enters the second heating tube inside the enzymatic tank through the inlet pipe. The tube wall of the second heating tube transfers heat to the outside, heating the water and phospholipase inside the enzymatic tank. The medium inside the second heating tube then enters the first heating tube through the connecting pipe. The tube wall of the first heating tube transfers heat to the outside, heating the vegetable oil inside the degumming tank. Finally, the medium flows to the return pipe and then to the external heat source for heating, forming a circulation pipeline to achieve effective heating.

[0029] Step 3: Turn on the drive motor. The drive shaft of the drive motor drives the first stirring rod to rotate. At the same time, through the transmission relationship between the first pulley, the second pulley and the transmission belt, the second stirring rod is driven to rotate. This causes the second stirring rod to stir the heated water and phospholipase, accelerate the rapid mixing of water and phospholipase and form an enzyme-containing aqueous solution. Then, the enzyme-containing aqueous solution is driven into the degumming tank through the booster pump and the delivery pipe.

[0030] Step 4: After the enzyme-containing aqueous solution inside the delivery pipe enters the degumming tank, it directly enters the annular tube. When the first stirring rod rotates, multiple transmission bars on the outside of the first stirring rod drive the annular seat and sealing ring to move in a circular motion on the inner wall of the annular groove and sealing groove. The water storage seat below the annular seat also moves in a circular motion. The enzyme-containing aqueous solution inside the annular tube enters the water storage seat directly through the through hole and is then sprayed outward by the nozzle at the bottom of the water storage seat. At the same time, during the movement of the water storage seat, the outer toothed ring at its top meshes with the inner toothed ring fixed on the inner surface of the transmission ring, causing the limiting frame to rotate relative to the mounting ring and the water storage seat. This causes the water storage seat and the nozzle at its bottom to rotate. The multiple nozzles at the bottom of the annular tube rotate on their own axis while revolving around the central axis, so that the enzyme-containing aqueous solution is sprayed into the vegetable oil more evenly.

[0031] Step 5: The first stirring rod rapidly mixes the heated enzyme-containing aqueous solution and vegetable oil. After mixing, the mixture is allowed to settle until sedimentation is complete. Then, the supernatant is discharged through the oil outlet, and the slag is discharged into the slag box through the slag discharge outlet.

[0032] This invention discloses an apparatus and process for enzymatic degumming of vegetable oils, which has the following beneficial effects:

[0033] 1. In use, the enzymatic degumming device for vegetable oil uses a first heating tube and a second heating tube to heat the inside of the degumming tank and the enzymatic tank using an internal high-temperature medium. The first stirring rod and the second stirring rod are driven by a drive mechanism to rotate. The second stirring rod mixes the phospholipase and water inside the enzymatic tank. The delivery pipe transports the uniformly mixed enzyme-containing aqueous solution inside the enzymatic tank to the degumming tank. After entering the degumming tank, the enzyme-containing aqueous solution directly enters the inside of the annular tube. Multiple nozzles rotate on their own axis while revolving around the first stirring rod and the rotating component, so that the enzyme-containing aqueous solution is sprayed into the vegetable oil relatively evenly.

[0034] 2. In this enzymatic degumming device for vegetable oil, the drive shaft of the drive motor drives the first stirring rod to rotate, and at the same time, through the transmission relationship of the first pulley, the second pulley and the transmission belt, the second stirring rod drives the second stirring rod to rotate, so that the second stirring rod stirs the heated water and phospholipase, accelerates the rapid mixing of water and phospholipase and forms an enzyme-containing aqueous solution, and then the enzyme-containing aqueous solution is driven into the degumming tank through the booster pump and the delivery pipe.

[0035] 3. The enzymatic degumming device for vegetable oil utilizes an external heat source to heat the medium flowing into the inlet pipe. The heated medium then enters the second heating tube inside the enzymatic tank through the inlet pipe. The tube wall of the second heating tube transfers heat to the outside, heating the water and phospholipase inside the enzymatic tank. The medium inside the second heating tube then enters the first heating tube through a connecting pipe. The tube wall of the first heating tube then transfers heat to the outside, heating the vegetable oil inside the degumming tank. Finally, the medium flows to the return pipe and then to the external heat source for heating, forming a circulation pipeline to achieve effective heating. Attached Figure Description

[0070] A process for enzymatic degumming of vegetable oils, comprising the following steps:

[0071] Step 1: First, add untreated vegetable oil into the degumming tank 1 through the oil inlet 104, and at the same time add water and phospholipase into the enzymatic tank 2 through the feed inlet 205.

[0072] Step 2: The medium flowing into the inlet pipe 206 is heated by an external heat source. After heating, the medium enters the second heating pipe 201 inside the enzymatic tank 2 through the inlet pipe 206. The wall of the second heating pipe 201 transfers heat to the outside to heat the water and phospholipase inside the enzymatic tank 2. Then, the medium inside the second heating pipe 201 enters the first heating pipe 101 through the connecting pipe 102. The wall of the first heating pipe 101 transfers heat to the outside to heat the vegetable oil inside the degumming tank 1. Finally, the medium flows to the return pipe 108 and then to the external heat source for heating to form a circulation pipeline, achieving an effective heating effect.

[0073] Step 3: Turn on the drive motor 401. The drive shaft 402 of the drive motor 401 drives the first stirring rod 103 to rotate. At the same time, through the transmission relationship of the first pulley 403, the second pulley 404 and the transmission belt 405, the second stirring rod 203 is driven to rotate. This causes the second stirring rod 203 to stir the heated water and phospholipase, accelerate the rapid mixing of water and phospholipase and form an enzyme-containing aqueous solution. Then, the enzyme-containing aqueous solution is driven into the degumming tank 1 through the booster pump 204 and the delivery pipe 202.

[0074] Step 4: The enzyme-containing aqueous solution inside the delivery pipe 202 enters the degumming tank 1 and then directly enters the annular pipe 3. When the first stirring rod 103 rotates, the multiple transmission bars 505 on the outside of the first stirring rod 103 drive the annular seat 502 and the sealing ring 503 to perform circular motion on the inner walls of the annular groove 5 and the sealing groove 501. The water storage seat 504 below the annular seat 502 also performs circular motion. The enzyme-containing aqueous solution inside the annular pipe 3 enters the water storage seat 504 directly through the through hole 509, and then... The nozzle 301 at the bottom of the water reservoir 504 sprays outwards. At the same time, during the movement of the water reservoir 504, the outer toothed ring 512 at its top meshes with the inner toothed ring 511 fixed on the inner surface of the transmission ring 510, causing the limiting frame 508 to rotate relative to the mounting ring 506 and the water reservoir 504. This causes the water reservoir 504 and the nozzle 301 at its bottom to rotate. As a result, the multiple nozzles 301 at the bottom of the annular tube 3 revolve around the central axis and rotate on their own axis, so that the enzyme-containing aqueous solution is sprayed into the vegetable oil more evenly.

[0075] Step 5: The first stirring rod 103 rapidly mixes the heated enzyme-containing aqueous solution and vegetable oil. After the mixing is completed, the mixture is allowed to settle until the sedimentation is complete. Then, the supernatant is discharged through the oil outlet 105, and the slag is discharged into the slag box 107 through the slag discharge outlet 106.

The connecting pipe (102) is set in two sections, and the two sections of the connecting pipe (102) are respectively connected to the inlet and outlet of the booster pump (204). The top of the second stirring rod (203) passes through the top of the enzyme tank (2) and extends upward through the fixed sleeve (207). The second stirring rod (203) is rotatably connected to the inner wall of the fixed sleeve (207). The top of the enzyme tank (2) is equipped with a feed inlet (205).

4. The apparatus for enzymatic degumming of vegetable oil according to claim 1, characterized in that, The outer peripheral wall of the drive shaft (402) and the outer peripheral wall of the top end of the second stirring rod (203) are respectively fixedly sleeved with the first pulley (403) and the second pulley (404), and the transmission belt (405) is connected between the first pulley (403) and the second pulley (404).

5. A process for enzymatic degumming of vegetable oil, based on the apparatus for enzymatic degumming of vegetable oil according to any one of claims 1-4, characterized in that, The process includes the following steps: Step 1: First, add untreated vegetable oil into the degumming tank (1) through the oil inlet (104), and at the same time add water and phospholipase into the enzymatic tank (2) through the feed inlet (205); Step 2: The medium flowing into the inlet pipe (206) is heated by an external heating source. After heating, the medium enters the second heating pipe (201) inside the enzymatic tank (2) through the inlet pipe (206). The pipe wall of the second heating pipe (201) transfers heat to the outside to heat the water and phospholipase inside the enzymatic tank (2). Then, the medium inside the second heating pipe (201) enters the first heating pipe (101) through the connecting pipe (102). The pipe wall of the first heating pipe (101) transfers heat to the outside to heat the vegetable oil inside the degumming tank (1). Finally, the medium flows to the return pipe (108) and then flows to the external heating source through the return pipe (108) to form a circulation pipeline, thus achieving an effective heating effect. Step 3: Turn on the drive motor (401). The drive shaft (402) of the drive motor (401) drives the first stirring rod (103) to rotate. At the same time, through the transmission relationship of the first pulley (403), the second pulley (404) and the transmission belt (405), the second stirring rod (203) is driven to rotate. This causes the second stirring rod (203) to stir the heated water and phospholipase, accelerate the rapid mixing of water and phospholipase and form an enzyme-containing aqueous solution. Then, the enzyme-containing aqueous solution is driven into the degumming tank (1) through the booster pump (204) and the delivery pipe (202). Step 4: The enzyme-containing aqueous solution inside the delivery pipe (202) enters the degumming tank (1) and then directly enters the annular pipe (3). When the first stirring rod (103) rotates, multiple transmission bars (505) on the outside of the first stirring rod (103) drive the annular seat (502) and the sealing ring (503) to perform circular motion on the inner walls of the annular groove (5) and the sealing groove (501). The water storage seat (504) below the annular seat (502) also performs circular motion. The enzyme-containing aqueous solution inside the annular pipe (3) enters the water storage seat (504) directly through the through hole (509). Then, the spray is sprayed outward from the nozzle (301) at the bottom of the water reservoir (504). At the same time, during the movement of the water reservoir (504), the outer toothed ring (512) at its top meshes with the inner toothed ring (511) fixed on the inner surface of the transmission ring (510), which causes the limiting frame (508) to rotate relative to the mounting ring (506) and the water reservoir (504), thereby causing the water reservoir (504) and the nozzle (301) at its bottom to rotate. Then, the multiple nozzles (301) at the bottom of the annular tube (3) rotate while revolving, so that the enzyme-containing aqueous solution is sprayed into the vegetable oil more evenly. Step 5: The first stirring rod (103) rapidly mixes the heated enzyme-containing aqueous solution and vegetable oil. After the mixing is completed, the mixture is allowed to settle until the sedimentation is complete. Then, the supernatant is discharged through the oil outlet (105), and the slag is discharged into the slag box (107) through the slag discharge port (106).
