Description

Technical Field

[0001] This utility model belongs to the field of fruit juice production, and in particular relates to a double-effect concentration unit for fruit juice processing. Background Technology

[0002] Fruit juice is a liquid food obtained by pressing or blending fresh fruit. It retains the natural sugars, vitamins, minerals, and fiber of the fruit. Fruit juice is widely popular due to its rich nutritional value and delicious taste. It can be consumed alone as a beverage or used to make various drinks, desserts, and cooking seasonings. Double-effect evaporators are often used for fruit juice concentration. They utilize the principle of double-effect evaporation to efficiently increase the concentration of fruit juice while maintaining its original flavor and nutritional components. Double-effect evaporators achieve fruit juice concentration through two evaporation stages: a first-effect stage and a second-effect stage. In the first-effect stage, the fruit juice is heated and evaporated, and the resulting steam is used for heating in the second-effect stage. In this way, the thermal energy of the steam is fully utilized, thereby improving energy efficiency.

[0003] Comparing with Chinese Patent No. CN220676766U, a dual-effect concentrator for traditional Chinese medicine extract is disclosed, including a heater; there are two heaters, and the middle of each heater is connected to an evaporation chamber through a pipe two. The bottom of each evaporation chamber is connected to the bottom of the adjacent heater through a pipe one. The top wall of each evaporation chamber is provided with a hollow tube. The hollow tube on the left is connected to the heater on the right through a pipe three. The hollow tube on the right is connected to a condenser through a pipe four. A storage tank is provided at the lower end of the condenser.

[0004] In the aforementioned patent, the liquid to be concentrated is heated and then evaporated and concentrated inside the evaporation chamber. The evaporation area is the same as the cross-section of the evaporation chamber, resulting in a small evaporation area and a slow evaporation rate. Therefore, a new device needs to be designed.

An evaporator 104 is located on one side of the heater 101. A conveying pipe 103 is connected between the top of the heater 101 and the evaporator 104. A discharge pipe 105 is located at the bottom of the evaporator 104, and a steam outlet pipe 106 is located at the top of the evaporator 104. A gas-liquid separator 107 is installed on the steam outlet pipe 106. The concentration component on the side furthest from the condenser is a single-effect concentration component, and the concentration component on the other side is a double-effect concentration component. In use, the feed valve 102 is opened to feed the juice into the heater 101, and the juice is then... Hot steam is introduced into the evaporator to heat the fruit juice. After the fruit juice is heated and boils, it is sent into the evaporator 104 through the conveying pipe 103 for rapid evaporation and gas-liquid separation. The separated fruit juice is returned to the heater 101 through the discharge pipe 105 at the bottom of the evaporator 104 for circulating heating and concentration. At this time, the steam in the first-effect evaporator 104 enters the second-effect heater 101 through the steam outlet pipe 106 at the top to heat the fruit juice in the second-effect heater 101, achieving double-effect heating and concentration. When the steam passes through the steam outlet pipe 106, it will flow through the gas-liquid separator 107. The gas-liquid separator 107 separates the concentrated fruit juice contained in the steam through the internal filter element and returns it to the corresponding evaporator 104.

The steam in the double-effect evaporator 104 is discharged into the condenser 203 for cooling and is finally discharged from the exhaust pipe 204. The condensate generated by cooling flows into the water storage tank 201 for collection and is discharged through the drain pipe 202.

[0027] In this embodiment: the dispersing component includes a motor 301, a rotating shaft 302 is mounted on the motor 301, a conical block 307 is mounted at the bottom of the rotating shaft 302, and a fixing structure is mounted at the top of the rotating shaft 302.

The fixing structure includes a fixing disc 303, with ten fixing rods 304 evenly arranged around its circumference. The dispersing disc 305 is umbrella-shaped and made of 304 stainless steel. After the juice is heated and boils, it flows through the conveying pipe 1... 03 is fed into the evaporator 104 and falls onto the dispersing plate 305. At this time, the motor 301 drives the rotating shaft 302 to rotate under the support of the conical block 307. The rotating shaft 302 drives the dispersing plate 305 to rotate through the fixed plate 303 and the fixed rod 304, so that the juice is evenly distributed on the surface of the dispersing plate 305, increasing the evaporation area, evaporating quickly, and realizing gas-liquid separation. A central tube 306 is set in the center of the dispersing plate 305, so that the steam generated below the dispersing plate 305 can be discharged upward into the top of the evaporator 104 through the central tube 306.

[0028] Working principle: The concentration unit on the side away from the condenser 203 is a single-effect concentration unit, and the concentration unit on the other side is a double-effect concentration unit. During use, the feed valve 102 is opened to feed the juice into the heater 101, and hot steam is introduced into the heater 101 to heat the juice. After being heated, the juice boils and is sent to the evaporator 104 through the conveying pipe 103, falling onto the dispersing plate 305. At this time, the motor 301 drives the rotating shaft 302 to rotate under the support of the conical block 307. The rotating shaft 302, through the fixed plate 303 and the fixed rod 304, drives the dispersing plate 305 to rotate, so that the juice is evenly distributed on the surface of the dispersing plate 305, increasing the evaporation area, accelerating evaporation, and achieving gas-liquid separation. The separated juice returns to the heater 101 through the discharge pipe 105 at the bottom of the evaporator 104 for recirculation heating. Concentration; A central pipe 306 is provided at the center of the dispersion plate 305, so that the steam generated below the dispersion plate 305 can be discharged upward into the top of the evaporator 104 through the central pipe 306. At this time, the steam in the first-effect evaporator 104 enters the second-effect heater 101 through the steam outlet pipe 106 at the top, heating the juice in the second-effect heater 101 to achieve double-effect heating and concentration. The steam in the second-effect evaporator 104 is discharged into the condenser 203 for cooling, and finally discharged from the exhaust pipe 204. The condensate generated by cooling flows into the water storage tank 201 for collection and is discharged through the drain pipe 202. When the steam passes through the steam outlet pipe 106, it will flow through the gas-liquid separator 107. The gas-liquid separator 107 separates the concentrated juice contained in the steam through the internal filter element and returns it to the corresponding evaporator 104.
