Description

Technical Field

[0001] The invention belongs to the field of flash tanks, and in particular relates to a syrup deodorizing flash tank for liquid cod liver oil and a deodorizing process. Background Art

[0002] Liquid cod liver oil is fat extracted from the livers of sharks, cod, etc. It is a yellow transparent liquid at room temperature. It is mainly composed of fatty acid glycerides with a high degree of unsaturation, in addition to a small amount of phospholipids and unsaponifiable matter. It is rich in vitamin A and vitamin D, and is often used to prevent and treat night blindness, corneal softening, rickets and osteomalacia. It also has a protective effect on epidermal tissues such as the upper mucosa of the respiratory tract. Ordinary liquid cod liver oil generally has a fishy smell, so it is usually necessary to add sweeteners such as starch syrup to the cod liver oil to remove the odor of the cod liver oil and improve the taste and aroma of the cod liver oil.

[0003] Flash liquefaction is an important process in the production of starch sugar, which directly affects the quality and yield of the final product. It uses amylase to convert starch into dextrin and oligosaccharides to increase the solubility of starch. This process is called "starch liquefaction" and is one of the main processes in the manufacturing process of starch sugar products. In the prior art, when the starch syrup is liquefied and flashed by a flash tank, the starch slurry is sprayed into the flash tank, and the temperature is flashed and cooled in the flash tank. After the high-pressure starch slurry enters the flash tank, the slurry is converted into steam and liquefied liquid due to the sudden decrease in pressure, wherein the liquefied liquid is discharged from the bottom of the flash tank and the steam is discharged from the top of the flash tank. However, during the flash evaporation process, part of the liquefied liquid will be entrained in the steam and discharged from the tank body, thereby reducing the yield of the liquefied liquid. At the same time, the starch slurry is sprayed into the flash tank at high pressure, which will cause impact vibration between the starch slurry and the flash tank, which will not only cause noise pollution, but also affect the service life of the flash tank.

[0015] The specific steps are as follows: Firstly, water and amylase are added into starch, and the mixture is stirred evenly to prepare starch slurry; The starch slurry is pumped into the tank body with a high pressure pump, so that the starch slurry enters the hydraulic rotary injection assembly through the feed port and the guide pipe in sequence. At this time, the hydraulic rotary injection assembly can start to rotate under the driving force of the hydraulic pressure when the starch slurry is fed, and the starch slurry is uniformly injected into the tank body during rotation, so as to flash the starch slurry to obtain steam and liquefied liquid, wherein the liquefied liquid falls into the lower end of the tank body and is discharged from the liquid outlet, the steam floats in the tank body, and the entrained liquefied liquid is filtered out by the gas-liquid separation filter to obtain dry steam, and finally the dry steam is discharged from the steam outlet; When the hydraulic rotary jet assembly rotates under the hydraulic drive of the starch slurry, the transmission assembly drives the reciprocating lifting assembly to move up and down reciprocatingly, so that the reciprocating lifting assembly reciprocatingly impacts and vibrates the gas-liquid separation filter screen, so as to shake off the liquefied liquid intercepted and filtered on the gas-liquid separation filter screen; liquefying the liquefied liquid obtained by flash evaporation in a laminar flow, adding saccharifying enzyme to the liquefied liquid to obtain an initial syrup, centrifuging the initial syrup, collecting the clear liquid, and subjecting the clear liquid to ion exchange to obtain a crude syrup, and evaporating and concentrating the crude syrup to obtain a deodorized syrup; Finally, the deodorizing syrup is added into the liquid cod liver oil and stirred thoroughly to remove the odor in the liquid cod liver oil.

[0016] The present invention has the following beneficial effects: 1.

By converting the hydraulic impact force during the starch slurry feeding into the rotational force of the hydraulic rotary jet assembly, the starch slurry sprayed into the tank body under high pressure can be buffered, and the starch slurry sprayed into the tank body under high pressure can be prevented from causing impact vibration between the starch slurry and the tank body, thereby generating noise pollution and damaging the tank body due to impact, which is beneficial to improving the service life of the flash tank. At the same time, through the rotational jetting of the hydraulic rotary jet assembly, the starch slurry can be more evenly distributed in the tank body, thereby improving the flash evaporation effect of the flash tank.

[0018] 3. In the present invention, the gas-liquid separation filter is installed on the inner wall of the tank body through an elastic support component, and when the hydraulic rotary injection component rotates under the hydraulic drive of the starch slurry, it can drive the reciprocating lifting component to move back and forth through the transmission component, so that the reciprocating lifting component can reciprocately impact and vibrate the gas-liquid separation filter, thereby vibrating and shaking off the liquefied liquid intercepted and filtered on the gas-liquid separation filter, preventing the liquefied liquid from continuously adhering to the gas-liquid separation filter and causing the gas-liquid separation filter to be blocked, thereby ensuring that the gas-liquid separation filter can work continuously and stably.

The reciprocating lifting component is connected to the hydraulic rotary injection component through the transmission component, so that when the hydraulic rotary injection component rotates under the hydraulic drive of the starch slurry, the reciprocating lifting component can be driven to move back and forth through the transmission component, so that the reciprocating lifting component can reciprocately impact and vibrate the gas-liquid separation filter 31; Specifically, when the flash tank is used, the prepared starch slurry is first pumped into the tank body 1 under high pressure, so that the starch slurry enters the hydraulic rotary injection assembly through the feed port 11 and the guide pipe 21 in turn. At this time, the hydraulic rotary injection assembly can start to rotate driven by the hydraulic pressure when the starch slurry is fed, and the starch slurry is uniformly injected into the tank body 1 during rotation, so as to flash the starch slurry to obtain steam and liquefied liquid, wherein the liquefied liquid falls into the lower end of the tank body 1 and is discharged from the liquid outlet 13, the steam floats in the tank body 1, and the entrained liquefied liquid is filtered out by the gas-liquid separation filter 31 to obtain dry steam, and finally the dry steam is discharged from the steam outlet 12; and when the hydraulic rotary injection assembly rotates under the hydraulic drive of the starch slurry, the reciprocating lifting assembly is driven to lift and lower reciprocately through the transmission assembly, so that the reciprocating lifting assembly reciprocatingly impacts and vibrates the gas-liquid separation filter 31, so as to vibrate and throw off the liquefied liquid intercepted and filtered on the gas-liquid separation filter 31; Among them, the steam generated by flash evaporation is filtered through the gas-liquid separation filter 31 to intercept and filter the liquefied liquid entrained in the steam, preventing the liquefied liquid from being discharged to the outside of the tank body 1 with the steam, which can improve the yield of the liquefied liquid and reduce the cost of removing the odor of liquid cod liver oil; by converting the hydraulic impact force when the starch slurry is fed into the feed into the rotational force of the hydraulic rotary injection assembly, the starch slurry injected into the tank body 1 at high pressure can be buffered, preventing the starch slurry from being injected into the tank body 1 at high pressure, causing impact vibration between the starch slurry and the tank body 1 and generating noise The pollution and impact damage to the tank body 1 are beneficial to prolonging the service life of the flash tank. At the same time, the rotary spraying of the hydraulic rotary spraying assembly can make the starch slurry more evenly distributed in the tank body 1, thereby improving the flash evaporation effect of the starch slurry; the reciprocating impact and vibration of the gas-liquid separation filter 31 by the reciprocating lifting assembly can vibrate and shake off the liquefied liquid intercepted and filtered on the gas-liquid separation filter 31, preventing the liquefied liquid from continuously adhering to the gas-liquid separation filter 31 and causing the gas-liquid separation filter 31 to be blocked, thereby ensuring that the gas-liquid separation filter 31 works continuously and stably. Embodiment 2

At this time, the liquid distribution pipe 23 rotates in a circular motion with the rotary joint 22 as a fulcrum under the recoil effect of the starch slurry sprayed out from the injection port 24, and drives the rotary joint 22 to rotate, thereby converting part of the hydraulic impact force of the starch slurry into the rotational mechanical motion of the rotary joint 22 and the liquid distribution pipe 23, so as to reduce the hydraulic impact force of the starch slurry during feeding. At the same time, the starch slurry is evenly distributed in the tank body 1 through the circularly moving liquid distribution pipe 23, so as to improve the uniformity of the starch slurry feeding and the flash evaporation effect.

[0027] Furthermore, a positioning shaft 26 is fixedly installed on the top of the rotary joint 22, and a bracket 25 is rotatably installed on the outer ring of the positioning shaft 26.

The rotary joint 22 is limited by the bracket 25 and the positioning shaft 26, which can improve the stability of the rotary joint 22 and the liquid distribution pipe 23 during rotation, and prevent the rotary joint 22 and the liquid distribution pipe 23 from being damaged by impact due to high-speed rotation.

The support ring frame 32 is fixedly mounted on the inner wall of the tank body 1. A plurality of connecting shafts 34 distributed in a circumference are fixedly mounted on the top surface of the support ring frame 32. The outer frame 33 is fixedly mounted on the outer ring of the gas-liquid separation filter 31. The inner ring of the outer frame 33 is also fixedly mounted with a support plate 37 supported on the bottom surface of the gas-liquid separation filter 31. Multiple connecting shafts 34 are slidably plugged into the outer frame 33, and a top plate 35 is fixedly installed on the top of the connecting shaft 34. The upper end of the connecting shaft 34 is movably sleeved with a pressure spring 36 that abuts between the top plate 35 and the top surface of the outer frame 33, and the lower end of the connecting shaft 34 is movably sleeved with a support spring 38 that abuts between the bottom surface of the outer frame 33 and the support ring frame 32.

[0029] When the hydraulic rotary injection assembly rotates under the action of the hydraulic pressure during starch slurry feeding, the hydraulic rotary injection assembly drives the active bevel gear 41 to rotate synchronously through the positioning shaft 26, and the active bevel gear 41 rotates to mesh with the driven bevel gear 42 to rotate, thereby driving the transmission shaft 48 and the eccentric wheel 44 to rotate, and the eccentric wheel 44 rotates through the circumferential slideway 414 and the guide shaft 415 to drive the lifting push rod 45 to reciprocate along the lifting guide rail 43. When the lifting push rod 45 moves up to the highest point, the top of the lifting guide rail 43 contacts the gas-liquid separation filter. The support plate 37 at the bottom end of the net 31 is used to impact and vibrate the support plate 37, the gas-liquid separation filter net 31 and the outer frame 33 upward, and when the lifting top rod 45 moves downward and separates from the support plate 37, the support plate 37, the gas-liquid separation filter net 31 and the outer frame 33 continue to vibrate under the elastic action of the pressure spring 36 and the support spring 38, so that the liquefied liquid filtered and intercepted by the gas-liquid separation filter net 31 is thrown off by the vibration, and the pressure spring 36 and the support spring 38 can provide buffering when the lifting top rod 45 moves upward to impact the support plate 37, so as to prevent the lifting top rod 45 and the support plate 37 from being damaged by the impact.

When the eccentricity of the eccentric wheel 44 is larger, the eccentric wheel 44 can drive the lifting top when rotating. The rod 45 moves upward to a higher position, thereby increasing the amplitude of impact vibration on the gas-liquid separation filter 31. Correspondingly, the smaller the eccentricity of the eccentric wheel 44 is, the lower the height to which the lifting push rod 45 can be driven to move upward when the eccentric wheel 44 rotates. At this time, the amplitude of impact vibration of the lifting push rod 45 on the gas-liquid separation filter 31 is reduced. Therefore, by adjusting the eccentricity of the eccentric wheel 44, the amplitude of the gas-liquid separation filter 31 can be changed, which is beneficial to improving the vibration and separation effect of the gas-liquid separation filter 31 on the liquefied liquid.

The support plate 37 is used to impact and vibrate the support plate 37, the gas-liquid separation filter 31 and the outer frame 33 upwards, and at the same time, the buffer spring 417 buffers the elastic end 46 and the support plate 37. Through the double buffering of the elastic end 46 and the buffer spring 417, the instantaneous impact force when the reciprocating lifting component and the gas-liquid separation filter 31 impact can be effectively reduced, thereby preventing the reciprocating lifting component and the gas-liquid separation filter 31 from being damaged by the impact force, which is beneficial to improving the service life of the reciprocating lifting component and the gas-liquid separation filter 31.
