Description

Technical Field

[0001] The utility model belongs to the technical field of plant extracts, in particular to vacuum concentration equipment for plant extracts. Background Art

[0002] Plant extracts refer to products that are made from plants as raw materials, and are subjected to physical and chemical extraction and separation processes according to the needs of the final product to obtain and concentrate one or more active ingredients in the plant without changing the structure of the active ingredients. The application range of plant extracts is very wide. In addition to the traditional use in Chinese medicine products, as people's trust and dependence on natural products gradually increase, a large part of plant extracts have been used in health care products and food ingredients. In the process of production and processing of plant extracts, the extract extracted by solvent needs to be concentrated to remove the solvent and other components in the solution, so as to facilitate the storage, transportation and further processing of plant extracts. When concentrating the solution, vacuum concentration equipment can greatly improve the concentration efficiency and reduce the labor intensity of the staff, but it still has the following disadvantages in actual use:

[0003] 1. The utility model with announcement number CN215782732U discloses a concentration device for plant extracts, and the membrane concentration device includes a raw material barrel, a feed pump and a membrane concentration component connected in sequence. The membrane concentration component includes a concentration membrane, a concentrate outlet and a dialysate outlet. The vacuum concentration device includes a frame and a vacuum tank. The outer wall of the vacuum tank is provided with a heating module. The vacuum tank is provided with an atomizing feeding group, a vacuum unit, a stirring group and a filter collector. The atomizing feeding group is connected to the discharge port of the membrane concentration device. The filter collector is provided with a first reflux pipe, and the reflux pipe is connected to the atomizing feeding group. Through the membrane concentration device, most of the water molecule solvent can be dialyzed out first, reducing the workload of subsequent vacuum concentration and improving the processing efficiency. However, during the processing, the structure of the membrane concentration device is usually more complicated, which increases the cost and maintenance expenses, and the area of ​​the dialysis membrane is usually more limited, so it takes a long time to analyze the water in the solution, prolonging the processing time, and the dialysis membrane is blocked after long-term use, which further leads to a decrease in processing efficiency;

[0004] 2. When vacuum concentration equipment is pre-treating plant extracts, it is usually difficult to accurately determine whether the treatment is completed, resulting in the actual pre-treatment time being longer than the required pre-treatment time. Plant extracts usually need to be vacuum concentrated at a certain temperature to ensure the concentration efficiency. Therefore, equipment is required to heat the plant extracts. During pre-treatment, the extracts are usually heated and evaporated to improve the processing efficiency, increasing production expenses. Utility Model Content

[0005] The utility model aims to provide a vacuum concentration device for plant extracts. Through a pretreatment box, a temperature control tank and a water pump, the utility model solves the problems that when the vacuum concentration device treats the solvent through a dialysis membrane, the dialysis membrane area is relatively limited, the treatment time is prolonged, and the dialysis membrane is easily clogged after long-term use, which reduces the treatment efficiency. It is difficult to accurately judge whether the treatment is completed during pretreatment, and the temperature of the extract needs to be controlled during both pretreatment and concentration treatment, which increases production expenses.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] The utility model is a vacuum concentration device for plant extract, comprising a pre-treatment box, a temperature control tank and a water pump, wherein a plurality of heating guide plates are fixedly connected inside the pre-treatment box, a weighing assembly is connected to the bottom of the pre-treatment box, a temperature control tank is arranged on one side of the pre-treatment box, a reflux pipe is welded through the top of the temperature control tank, an air intake pipe is welded through one end of the outer peripheral surface of the temperature control tank, a water pump is connected through the bottom of one end of the pre-treatment box, a spray pipe is arranged on the top of the water pump, a vacuum concentration tank is arranged on one side of the water pump, and the vacuum concentration tank is located inside the temperature control tank;

[0008] The guided extract can be heated by the heating guide plate to increase the volatilization rate of the solvent. The extract is guided by multiple guide plates, which can further increase the contact area between the solvent and the air and increase the volatilization rate of the solvent. The structure is simple and the operation is convenient. The treatment liquid in the pretreatment box can be weighed by the weighing component. When the weight does not change within a certain period of time, it is judged that the treatment of the extract is completed, which is convenient for accurately controlling the pretreatment time and improving the processing efficiency. The high-temperature air containing the evaporated solvent enters the temperature control tank through the air intake pipe, and the solvent is condensed through the reflux pipe, so that the solvent at a certain temperature falls to the inside of the temperature control tank to keep the vacuum concentration tank warm, so that the extract is concentrated at an appropriate temperature, reducing the amount of electricity required for heating, and facilitating the recovery of the solvent. The extract in the pretreatment box can be pumped into the spray pipe by a water pump, so that the extract circulates in the pretreatment tank, and the contact area with the air is increased by the guide plate for rapid volatilization. When the solvent in the extract is completely evaporated, the extract can be pumped into the vacuum concentration tank by the water pump, thereby improving the automation of the equipment.

[0009] Furthermore, a liquid inlet pipe is welded through the bottom of the pre-processing box, a control component is clamped and fixed on the top of the weighing component, and a plurality of guide frames are welded and fixed in the pre-processing box, and the guide frames are located on the top of the heating guide plate;

[0010] The equipment can be controlled by the control component to improve the convenience of use. The weight of the extract can be weighed by the weighing component. When the weight of the extract changes below a threshold within a certain period of time, the control component can control the water pump to pump the extract into a vacuum concentration tank for processing, thereby reducing the pre-processing time and improving production efficiency.

[0011] Furthermore, the other end of the air inlet pipe relative to the temperature control tank is connected to one end of the pre-treatment box, the air inlet pipe is located at one end of the heating guide plate, and a drainage pipe is welded to the bottom end of the outer peripheral surface of the temperature control tank;

[0012] The guide frame can guide the extract pumped to a high place by the water pump, so that the extract flows back to the bottom of the pretreatment box through multiple heating guide plates. The multiple heating guide plates can increase the contact area between the extract and the air, improve the volatilization efficiency, and heat the extract to further increase the volatilization speed. At the same time, the extract and the solvent can be heated to a high temperature, which is convenient for subsequent vacuum concentration treatment and improves production efficiency.

[0013] Furthermore, a plurality of heat dissipation fins are welded and fixed on the outer peripheral surface of the return pipe, a blower is inserted through one end of the return pipe and clamped, the blower is located at the other end of the return pipe relative to the temperature control tank, the blower is inserted through one end of the pre-treatment box and clamped, the blower is located at the other end of the pre-treatment box relative to the intake pipe;

[0014] The blower can drive the flow of air, and the fast-flowing air can further increase the volatilization rate of the solvent and improve the pre-treatment efficiency. The heat dissipation fins can cool the high-temperature air, causing the solvent to condense and flow back into the temperature control tank. The temperature control tank can collect the cooled solvent to facilitate subsequent solvent recovery and treatment. The vacuum concentration tank can also be insulated to reduce the heat required for heating the vacuum concentration tank and reduce production expenses.

[0015] Furthermore, a first connecting pipe is inserted through the top of the water pump, a second connecting pipe is inserted through one end of the outer circumference of the first connecting pipe, a solenoid valve is inserted through one end of the outer circumference of the second connecting pipe, the spray pipe is inserted through the top of the first connecting pipe, and the spray pipe is inserted through one end of the pre-treatment box;

[0016] The extract can be pumped to a high place by a water pump and guided by multiple heated guide plates, so that the extract circulates in the pretreatment tank and quickly evaporates by increasing the contact area with the air through the guide plates.

[0017] Furthermore, a liquid outlet pipe is inserted through the bottom end of the outer peripheral surface of the vacuum concentration tank, and the liquid outlet pipe is inserted through the outer peripheral surface of the temperature control tank, and the other end of the second connecting pipe relative to the first connecting pipe is inserted through the top of the outer peripheral surface of the vacuum concentration tank;

[0018] After the pretreatment is completed, by opening the solenoid valve, the water pump can pump the extract through the first connecting pipe and the second connecting pipe into the vacuum concentration tank for concentration treatment, thereby improving the automation level of the equipment.

[0019] The utility model has the following beneficial effects:

[0020] 1. The utility model solves the problem that the membrane concentration device can dialyze out most of the water molecule solvent first, reduce the workload of subsequent vacuum concentration, and improve processing efficiency by arranging a pretreatment box, a temperature control tank and a water pump. However, in the processing process, the structure of the membrane concentration device is usually more complicated, which increases costs and maintenance expenses, and the area of ​​the dialysis membrane is usually more limited, so it takes a long time to analyze the water in the solution, which prolongs the processing time, and the dialysis membrane is blocked after long-term use, which further leads to a decrease in processing efficiency. The extract in the pretreatment box is pumped to a high place by a water pump, and is heated and guided by multiple heating guide plates to increase the contact area between the extract and the air, improve the volatilization efficiency of the solvent, and further increase the volatilization speed of the solvent by the flow of air and the heating of the extract, thereby avoiding the problem of clogging of the dialysis membrane after long-term use.

[0021] 2. The utility model solves the problem that it is usually difficult to accurately judge whether the treatment is completed when the vacuum concentration equipment pre-treats the plant extract, resulting in the actual pre-treatment time being longer than the required pre-treatment time, and the plant extract usually needs to be vacuum concentrated at a certain temperature to ensure the concentration efficiency. Therefore, the equipment is required to heat the plant extract, and the pre-treatment usually involves heating and evaporating the extract to improve the treatment efficiency, which increases the production cost. The weight of the extract in the pre-treatment box can be weighed by a weighing component, and the extract can be pumped into the vacuum concentration tank by a water pump when the weight change is small, the extract and the solvent can be heated by a heating guide plate, and the vacuum concentration tank can be kept warm by the flowing hot air and the solvent collected in the temperature control tank, thereby reducing the amount of electricity consumed in heating the vacuum concentration tank and reducing production costs.

[0031] The extracted plant extract is poured into the pretreatment box 1, and the extract is pumped to a high place in the pretreatment box 1 by the water pump 3. The extract is guided by multiple heating guide plates 104 under the action of gravity to increase the contact area between the solvent and the air, and the extract is heated by the heating guide plates 104 to increase the volatilization rate of the solvent.
