Abstract
Description
Technical Field
[0001] This utility model relates to the field of food processing technology, specifically to a high-efficiency evaporator for food processing. Background Technology
[0002] Evaporators play an important role in food concentration processing and are widely used in the processing of concentrated fruit juices, dairy products, sauces and other food raw materials. They evaporate the water in food by heating, thereby increasing the product concentration and taste.
[0003] Existing food concentration evaporators typically heat the medium only on the outer periphery of the container, and the steam generated cannot be directly reused in the medium, resulting in low heating efficiency in the central area of the container. Therefore, a high-efficiency evaporator for food processing is proposed. Utility Model Content
[0004] To address the problems in the existing technology, this utility model provides a high-efficiency evaporator for food processing, which provides a set of evaporators with high heat transfer efficiency for the concentration processing of food. The steam generated by heating is passed through a stainless steel jacket to better heat the medium located in the middle of the tank, so as to compensate for the situation where the heating medium cannot directly heat the middle area of the tank, thereby improving the heating efficiency. Furthermore, the heating and concentration medium in the tank is stirred by stirring blades, which improves the uniformity of the concentration of the heating and concentration medium.
[0005] The technical solution adopted by this utility model to solve its technical problem is a high-efficiency evaporator for food processing, including a tank, a vacuum pump, stirring blades and a stainless steel jacket. The stainless steel jacket is located at the center of the tank, the vacuum pump is located on one side of the tank, the top of the tank is covered with a tank cover, a feed valve is provided on one side of the top of the tank cover, and a motor is installed on the top of the tank cover. The drive end of the motor is installed with a shaft through the tank cover. The stirring blades are located at the bottom of the stainless steel jacket, and the shaft is installed and connected to the stirring blades through the stainless steel jacket.
[0006] By adopting the above technical solution, an evaporator with high heat transfer efficiency is provided for the concentration processing of food through a component consisting of a tank, a vacuum pump, stirring blades, and a stainless steel jacket. The steam generated by the heated medium in the tank passes through the stainless steel jacket located in the middle of the tank before being discharged to the outside. This allows the steam generated by heating to better heat the medium in the middle of the tank through the stainless steel jacket, thus compensating for the situation where the heating medium cannot directly heat the middle area of the tank, resulting in better heating efficiency. The stirring blades also stir the heated and concentrated medium in the tank, resulting in better uniformity of the concentration of the heated and concentrated medium.
[0007] Specifically, the stainless steel jacket has a rod hole at its center for the shaft to pass through, and the top and bottom of the rod hole are sealed to the shaft by sealing rings. The inner cavity of the stainless steel jacket has a steam flow chamber for steam transportation.
[0008] Specifically, a support pipe is connected to the outer periphery of the top of the stainless steel jacket. The end of the support pipe away from the stainless steel jacket is fixedly connected to the tank body. The support pipe communicates with the steam flow chamber, and a steam inlet is opened at the top of the support pipe.
[0009] By adopting the above technical solution, the steam generated by the heated medium inside the tank enters the steam flow chamber through the steam inlet of the support pipe, and the heat of the steam is conducted to the central area of the tank by the stainless steel jacket, thereby ensuring that the heat in the central position of the tank remains at a high temperature.
[0010] Specifically, a steam vent pipe is connected to the bottom of one side of the stainless steel jacket. The steam vent pipe is connected to the steam flow chamber. The end of the steam vent pipe away from the stainless steel jacket passes through the tank body and is fitted with a flange joint. The air inlet end of the vacuum pump is connected to the flange joint. The contact surface between the steam vent pipe and the tank body is welded and sealed.
[0011] By adopting the above technical solution, the air in the steam flow chamber is discharged through the exhaust pipe by the vacuum pump to the flange joint, and the tank is kept in a certain vacuum state to reduce the boiling point of the heated medium and improve the evaporation efficiency.
[0012] Specifically, the tank body includes a jacket, and a lower ball valve and an upper ball valve are respectively provided at the top and bottom of both sides of the jacket, and a drain ball valve is connected to the bottom of the jacket.
[0013] By adopting the above technical solution, the medium in the tank is discharged to the outside by opening the drain ball valve.
[0014] The beneficial effects of this utility model are as follows: The assembly, consisting of a tank, a vacuum pump, stirring blades, and a stainless steel jacket, provides a high-efficiency evaporator for food concentration processing. The steam generated by the heated medium in the tank passes through the stainless steel jacket located in the middle of the tank before being discharged externally. This allows the steam generated by heating to better heat the medium in the middle of the tank, enabling secondary utilization of the evaporated steam. This compensates for the inability of the heating medium to directly heat the central area of the tank, resulting in better heating efficiency. Furthermore, the stirring blades agitate the heated and concentrated medium within the tank, improving the uniformity of the concentration. This solves the problem of low heating efficiency in the central area of the container in existing food concentration evaporators, where the heating location is mostly on the outer periphery of the container and the evaporated steam cannot be directly reused.

Detailed Implementation
[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] like Figure 1-4 As shown, the present invention discloses a high-efficiency evaporator for food processing, comprising a tank body 1, a vacuum pump 3, a stirring blade 6, and a stainless steel jacket 7. The stainless steel jacket 7 is located at the center of the tank body 1, the vacuum pump 3 is located on one side of the tank body 1, the top of the tank body 1 is covered with a tank cover 2, a feed valve 21 is provided on one side of the top of the tank cover 2, and a motor 4 is installed on the top of the tank cover 2. The drive end of the motor 4 passes through the tank cover 2 and is mounted with a shaft 5. The stirring blade 6 is located at the bottom of the stainless steel jacket 7, and the shaft 5 passes through the stainless steel jacket 7 and is connected to the stirring blade 6.
[0023] In use, the tank 1, vacuum pump 3, stirring blades 6, and stainless steel jacket 7 provide a high-efficiency evaporator for food concentration processing. The steam generated by the heated medium in the tank 1 passes through the stainless steel jacket 7 located in the middle of the tank 1 before being discharged to the outside. This allows the steam generated by heating to better heat the medium in the middle of the tank 1 through the stainless steel jacket 7, realizing the secondary utilization of the steam generated by heating and evaporation. This compensates for the situation where the heating medium cannot directly heat the middle area of the tank 1, resulting in better heating efficiency. The stirring blades 6 also stir the heated and concentrated medium in the tank 1, making the concentration of the heated and concentrated medium more uniform.
[0024] The present invention also includes a rod hole 71 provided at the center of the stainless steel jacket 7 for the shaft 5 to pass through, the top and bottom of the rod hole 71 being sealed to the shaft 5 by a sealing ring, and a steam flow chamber 72 for steam transportation being provided in the inner cavity of the stainless steel jacket 7.
[0025] The present invention also includes a support pipe 73 connected to the outer periphery of the top of the stainless steel jacket 7. The end of the support pipe 73 away from the stainless steel jacket 7 is fixedly connected to the tank body 1. The support pipe 73 communicates with the steam flow chamber 72. A steam inlet 74 is opened at the top of the support pipe 73.
[0026] During use, the steam generated by the heated medium inside the tank 1 enters the steam flow chamber 72 through the steam inlet 74 of the support pipe 73. The stainless steel jacket 7 conducts the heat of the steam to the central area of the tank 1, thereby ensuring that the heat in the central area of the tank 1 remains at a high temperature.
[0027] The present invention also includes a steam exhaust pipe 75 connected to the bottom of one side of the stainless steel jacket 7, the steam exhaust pipe 75 communicating with the steam flow chamber 72, the end of the steam exhaust pipe 75 away from the stainless steel jacket 7 passing through the tank body 1 and equipped with a flange joint 76, the air inlet end of the vacuum pump 3 being connected to the flange joint 76, and the contact surface between the steam exhaust pipe 75 and the tank body 1 being welded and sealed.
[0028] When in use, the vacuum pump 3 is turned on to draw air from the flange joint 76, so that the air in the steam flow chamber 72 is discharged through the exhaust pipe 75. At the same time, the tank 1 is kept in a certain vacuum state to reduce the boiling point of the heated medium and improve the evaporation efficiency.
[0029] The present invention also includes a jacket 11, wherein a lower ball valve 12 and an upper ball valve 13 are respectively provided at the top and bottom of both sides of the jacket 11, and a drain ball valve 14 is connected to the bottom of the jacket 11.
[0030] When in use, personnel can open the drain ball valve 14 to discharge the concentrated medium in tank 1 to the outside.
[0031] In use, the required concentrated and evaporated food raw materials are injected into the jacket 11 and stainless steel jacket 7 through the feed valve 21. The heat exhaust end of the external heating device is connected to the lower ball valve 12, and the upper ball valve 13 is connected to the heat recovery end of the heating device. The heating device can be a hot oil heater or a steam heater. The power supply components in the work area provide power to the electrical mechanism of this application. During the evaporation process, the external heating medium enters the inner wall of the jacket 11 through the lower ball valve 12, causing the jacket 11 to heat the food raw materials. At the same time, the motor 4 drives the shaft 5 to rotate the stirring blades 6, which improves the heating uniformity. The vacuum pump 3 evacuates air from the flange joint 76. The food ingredients inside the tank 1 are heated under a certain vacuum negative pressure environment to lower the boiling point. After the food ingredients are heated and evaporated, the steam generated by evaporation enters the steam flow chamber 72 through the steam inlet 74 of the support pipe 73. The stainless steel jacket 7 conducts the heat of the steam to the central area of the tank 1, thereby ensuring that the heat in the central area of the tank 1 is kept at a high temperature. This allows for the secondary utilization of the steam generated by heating and evaporation, making up for the situation where the heating medium cannot directly heat the central area of the tank 1, thus improving the heating efficiency. After the food is concentrated and evaporated, the personnel open the drain ball valve 14 to discharge the concentrated medium in the tank 1 to the outside, completing the efficient evaporation operation of the food.
