Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of functional sugar production and processing, and specifically relates to a low-temperature evaporation system in functional sugar production. Background Technique
[0002] In modern industrial production, evaporation technology is widely used in various institutions. Especially in the sugar processing process, the evaporator has the characteristics of short material residence time, low resistance, and high heat transfer efficiency. Especially the short residence time is particularly important for sugar production. It can not only achieve the purpose of low-temperature evaporation of syrup but also avoid coloring of syrup at high temperatures. In the current technology, generally, the evaporator uses the circulating water in the cooling tower to cool the condenser to achieve the system vacuum degree, so that the material is evaporated at a low temperature. However, due to different properties of some sugars, they are still prone to coloring even under such conditions. This requires a lower boiling point to evaporate the material. How to reduce the boiling point of the material in the evaporation system is a technical problem faced currently. Content of the Utility Model
[0003] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a low-temperature evaporation system in functional sugar production to solve the problems put forward in the above background technique.
[0004] To achieve the above purpose, the utility model adopts the following technical scheme: A low-temperature evaporation system in functional sugar production, including an evaporation device. The secondary gas discharge port of the evaporation device is connected to the intake port of the first vacuum pump through a pipeline. An air storage tank is arranged on the pipeline between the evaporation device and the first vacuum pump. The exhaust port of the first vacuum pump is connected to the intake port of the condenser through a pipeline. The discharge port of the condenser is connected to the receiving port of the steam-water separator through a pipeline. The exhaust port of the steam-water separator is connected to the second vacuum pump through a pipeline. The liquid discharge port of the steam-water separator is connected to the condensate tank through a pipeline. The condenser is connected to the refrigeration unit through a pipeline, and a cold air unit is arranged in the installation channel of the condenser.
[0005] Preferably, the first vacuum pump is a Roots vacuum pump.
[0006] Preferably, the second vacuum pump is a slide valve type vacuum pump.
[0007] Preferably, the condenser is a steam condenser.
[0008] Preferably, the steam-water separator is a centrifugal type steam-water separator.
[0009] Preferably, the evaporation device is a triple-effect evaporator device.
[0010] Preferably, the cooling cold water generated by the refrigeration unit is not higher than 7°C.
[0011] Preferably, the air supply direction of the air cooler unit is opposite to the flow direction of the steam in the condenser.
[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:
[0013] The present utility model provides a low-temperature evaporation system in the production of functional sugars. The secondary gas in the evaporation device is extracted by a vacuum pump, and the condenser is cooled by the cooling water generated by the air cooler unit and the refrigeration unit, which improves the cooling effect of the condenser, increases the heat exchange capacity of the condenser, enables more waste gas to be condensed, and more waste gas discharged will reduce the internal pressure of the evaporation device, lowering the boiling point of the material, ensuring that the material can evaporate at a lower temperature. At the same time, the evaporation at a lower temperature can also prevent the syrup from coloring at high temperatures, greatly improving the sensory properties of the product and increasing the added value of the product.

However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.
[0019] The attached drawing shows a specific embodiment of the present utility model. This embodiment aims to provide a low-temperature evaporation system in sugar production, including an evaporation device 1. The secondary gas discharge port of the evaporation device 1 is connected to the intake port of a first vacuum pump 3 through a pipeline to accelerate the discharge of secondary gas. An air storage tank 2 is arranged on the pipeline between the evaporation device 1 and the first vacuum pump 3 to store the extracted secondary gas. The exhaust port of the first vacuum pump 3 is connected to the intake port of a condenser 5 through a pipeline to introduce the extracted secondary gas into the condenser 5 for condensation. The discharge port of the condenser 5 is connected to the receiving port of a steam-water separator 7 through a pipeline to introduce the condensed liquid and non-condensable gas into the steam-water separator 7. The exhaust port of the steam-water separator 7 is connected to a second vacuum pump 9 through a pipeline to evacuate the non-condensable gas through the second vacuum pump 9 to ensure the system vacuum degree. The drain port of the steam-water separator 7 is connected to a condensate tank 8 through a pipeline to introduce the condensed water into the condensate tank 8 for reuse. The condenser 5 is connected to a refrigeration unit 4 through a pipeline, and a cold air unit 6 is arranged in the installation channel of the condenser 5 to cool down the condenser 5 through the refrigeration unit 4 and the cold air unit 6 to improve the heat exchange capacity of the condenser 5.
[0020] In order to better accelerate the discharge of secondary gas, a Roots vacuum pump is selected for the first vacuum pump 3.
[0021] In order to better evacuate the non-condensable gas, a sliding vane vacuum pump is selected for the second vacuum pump 9.
[0022] In order to improve the condensation effect and accelerate the condensation of secondary gas, a steam condenser is selected for the condenser 5.
[0023] In order to better and faster separate the condensed water and non-condensable gas, a centrifugal steam-water separator is selected for the steam-water separator 7.
[0024] In order to improve the utilization rate of the evaporation system, the evaporation device 1 is a triple-effect evaporator device.
[0025] In order to increase the heat transfer effect of the condenser 5 and accelerate the cooling of the cold medium in the condenser 5, the cooling cold water generated by the refrigeration unit 4 is not higher than 7°C.
[0026] In order to better cool down the condenser 5, the air supply direction of the cold air unit 6 is set opposite to the flow direction of the steam in the condenser 5.
[0027] The principle of the present utility model is as follows: Fresh steam enters the evaporation device 1 for an evaporation reaction. The secondary gas after the reaction is discharged through the secondary gas exhaust port of the evaporation device 1 and enters the condenser 5 through the air storage tank 2 under the action of the first vacuum pump 3. The condenser 5 condenses the secondary gas. During the condensation process, the cold air unit 6 and the refrigeration unit 4 continuously generate cold air and cold water to continuously cool the condenser 5 itself and the cold medium of the condenser 5, improving the condensation effect of the condenser 5, accelerating the condensation of the secondary gas, enabling it to be discharged faster, reducing the air pressure in the evaporation device 1, thereby reducing the boiling point of the syrup, enabling it to evaporate at a lower boiling point, and also avoiding the coloring of the syrup at high temperatures. The condensed condensate and non-condensable gas enter the steam-water separator 7, and the condensate and non-condensable gas are separated through the steam-water separator 7. The separated condensate enters the condensate tank 8 for subsequent reuse, and the separated non-condensable gas is discharged through the second vacuum pump 9 to ensure the vacuum degree of the system.
