Description

Technical Field

[0001] The utility model belongs to the technical field of material component extraction, and particularly relates to an aroma recovery device with single-effect concentration. Background Technique

[0002] Some plants are deeply loved by people because of their unique fragrance. It is very necessary to extract and retain these aromas. Whether the existing methods for extracting and concentrating the aroma in the feed liquid adopt single-effect evaporation concentration or multi-effect evaporation concentration, finally the extracted aroma concentrated liquids are combined together. However, within a certain period of time when the concentrated feed liquid just starts to evaporate and vaporize, there will be top note components, and then when the evaporation continues, its top note components may gradually decrease or even disappear. How to separate the top note components from the residual note components has become a difficult problem to solve at present. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an aroma recovery device with single-effect concentration. By setting a three-way discharge valve at the outlet of the cooler and connecting different receiving tanks, and installing a switching valve on the inlet pipeline of the receiving tank, and then controlling the opening and closing of the three-way discharge valve and the switching valve according to the evaporation temperature and time, so that the top note liquid and the residual note liquid enter different receiving tanks, and the top note components and the residual note components are separated.

[0004] To solve the above technical problem, the utility model provides an aroma recovery device with single-effect concentration, which includes a heater, an evaporator, a cooler, a first receiving tank and a second receiving tank. The top of the heater is connected to the evaporator, and the evaporator is connected to the air inlet of the cooler. A feed control valve is arranged at the feed inlet of the heater, and a temperature sensor is arranged inside the heater. The temperature sensor is connected to a temperature controller. A three-way discharge valve is arranged at the liquid outlet of the cooler. The three-way discharge valve communicates with the inner cavity of the cooler, a first pipeline and a second pipeline respectively. The first pipeline is connected to the inlet of the first receiving tank, and a first switching valve is arranged on the first pipeline. The second pipeline is connected to the inlet of the second receiving tank, and a second switching valve is arranged on the second pipeline. The feed control valve, the time controller, the temperature controller, the three-way discharge valve, the first switching valve and the second switching valve are all connected to a PLC controller, and the PLC controller is also connected to the time controller.

[0005] When the plant concentrate enters the heater and evaporator for heating and evaporation, top note components will be generated. The PLC controls the opening of the first switching valve and the three-way discharge valve. The vaporized steam enters the cooler for condensation and cooling, and then enters the first receiving tank through the three-way discharge valve and the first switching valve, and thus a top note liquid with sufficient top note aroma can be obtained. When the set time is reached, the PLC controls the opening of the second switching valve and the three-way discharge valve. The steam continues to enter the cooler for condensation and cooling, and enters the second receiving tank through the three-way discharge valve and the second switching valve, thereby separating the top note liquid and the residual note liquid. When new feed liquid needs to be added to the heater, the PLC controls the simultaneous opening of the feed control valve, the three-way discharge valve and the first switching valve. After the feeding is completed, the feed control valve is closed, and the three-way discharge valve and the first switching valve continue to be opened until the set time, so that the top note liquid with sufficient top note aroma enters the first receiving tank.

[0006] As a further description of the above technical solution:

[0007] The first receiving tank is also connected to the vacuum pipeline through the third switching valve, and the second receiving tank is connected to the vacuum pipeline through the fourth switching valve. The vacuum pipeline is connected to the vacuum system, and the third switching valve and the fourth switching valve are also connected to the PLC controller. The third switching valve and the fourth switching valve open and close respectively in coordination with the opening and closing of the first switching valve and the second switching valve, so that the inside of the single-effect concentrator is always under high vacuum conditions, which can reduce the concentration and evaporation temperature.

[0008] As a further description of the above technical solution:

[0009] The cooler consists of a condensation tank and a cooling tank. The liquid outlet of the condensation tank is connected to the liquid inlet of the cooling tank. A cooling water jacket is provided outside the tank body of the condensation tank, and an S-shaped cooling water pipe is provided inside the tank body of the cooling tank. The cooling water outlet of the condensation tank is connected to the cooling water inlet of the cooling tank. The vaporized substance containing aroma components is first condensed into a high-temperature aroma liquid by the condenser, and then flows into the cooling tank for further cooling to a lower temperature, and then enters the receiving tank for storage. The condensation tank only has an interlayer cooling outside the tank body, which can make the condensed liquid fall quickly and effectively reduce wall hanging; the cooling tank adopts an S-shaped cooling water pipe to achieve the purpose of rapid cooling.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0011] By setting a three-way discharge valve at the outlet of the cooler and connecting it to the first receiving tank and the second receiving tank respectively, setting a first switching valve on the inlet pipeline of the first receiving tank, setting a second switching valve on the inlet pipeline of the second receiving tank, and then automatically controlling the opening and closing of each valve by the PLC according to the evaporation temperature and time, so that the top note liquid and the residual note liquid enter the first receiving tank and the second receiving tank respectively, and the purpose of separating the top note components and the residual note components is achieved.

A feed control valve 11 is provided at the feed inlet of the heater 10. A temperature sensor and a pressure sensor are provided inside the heater 10. The temperature sensor is connected to a temperature controller, and the pressure sensor is connected to a pressure controller. The top of the heater 10 is connected to the air inlet of the evaporator 20. The bottom of the evaporator 20 is connected to the bottom of the heater 10 through a discharge pipe. The evaporator 20 is connected to the cooler. The cooler consists of a condensation tank 41 and a cooling tank 42.

An S-shaped cooling water pipe 43 is provided inside the tank body of the cooling tank 42. The condensation tank 41 condenses the gas inside it to liquefy it into an aroma liquid containing aroma components. At this time, the temperature of the aroma liquid is still relatively high and needs to be further cooled. The high-temperature aroma liquid directly enters the cooling tank 42 for cooling. The setting of the S-shaped cooling water pipe 43 can increase the contact surface between the aroma liquid and the cooling water to achieve the purpose of rapid cooling. A three-way discharge valve 50 is provided at the liquid outlet of the cooling tank 42. The three-way discharge valve 50 communicates with the inner cavity of the cooler 42, a first pipe and a second pipe respectively. The first pipe is connected to the inlet of the first receiving tank 61, and a first switch valve 51 is provided on the first pipe. The second pipe is connected to the inlet of the second receiving tank 62, and a second switch valve 52 is provided on the second pipe. The first receiving tank 61 is also connected to the vacuum pipe through a third switch valve 53. The second receiving tank 62 is connected to the vacuum pipe through a fourth switch valve 54.

The PLC controller is also connected to the time controller and the pressure controller.

[0017] When the concentrated liquid enters the heater 10 and the evaporator 20 and starts to evaporate and vaporize in the evaporator 20, top note components will be generated. The PLC controls to open the first switching valve 51, the third switching valve 53 and the three-way discharge valve 50. After the vaporized steam enters the cooler for condensation and cooling under vacuum conditions, it enters the first receiving tank 61 through the three-way discharge valve 50 and the first switching valve 51, and thus top note liquid with sufficient top note aroma can be obtained. When the set time is reached, the PLC controls to open the fourth switching valve 54, the second switching valve 52 and the three-way discharge valve 50. After the steam enters the cooler for condensation and cooling under vacuum conditions, it enters the second receiving tank 62 through the three-way discharge valve 50 and the second switching valve 52, thereby separating the top note liquid and the residual note liquid. When new feed liquid needs to be added to the heater 10, the PLC controls the feed control valve 11, the three-way discharge valve 50 and the first switching valve 51 to be opened simultaneously. After the feeding is completed, the feed control valve 11 is closed, and the three-way discharge valve 50 and the first switching valve 51 remain open for the set time to allow the top note liquid with sufficient top note aroma to enter the first receiving tank 61.
