Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of food processing equipment for food that is both food and medicine, and in particular to a device for extracting Chinese herbal medicines in food processing that is both food and medicine. Background Technology
[0002] In the processing of food products that are both food and medicine, the extraction of effective components from traditional Chinese medicine is a key step. Common extraction devices often use overall heating and single stirring, which has some shortcomings in actual use. Different active components in medicinal materials often need to be dissolved better at specific temperatures, and overall high temperature can easily destroy some heat-sensitive components. Meanwhile, uniform stirring intensity is difficult to adapt to the mass transfer requirements of different temperature layers, affecting extraction efficiency. Although some devices have tried to improve heating or stirring methods, most of them have complex structures, insufficient temperature control accuracy, and the heat in different areas is easily affected by each other, resulting in limited actual effects.
[0003] Therefore, there is a need for an extraction device that can achieve precise zoned temperature control and match the mass transfer requirements at different temperatures. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies that employ overall heating and single stirring, where high overall temperature can easily destroy some heat-sensitive components. Therefore, this invention proposes a herbal extraction device for food processing that is both food and medicine.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A device for extracting Chinese herbal medicines in food processing, which is used to extract substances from Chinese herbal medicines after the cell walls are broken. The device includes a horizontal mounting platform on which an extraction tank is fixedly mounted by bolts. Gradient temperature control mechanism; the gradient temperature control mechanism is fixed inside the extraction tank and is used to match the mass transfer requirements of different temperature layers, so as to avoid component damage caused by overall high temperature and improve the extraction rate of target components.
[0006] Furthermore, the gradient temperature control mechanism includes a low-temperature cavity, a medium-temperature cavity, and a high-temperature cavity fixed from top to bottom on the inner wall of the extraction tank. A platinum resistance temperature sensor for monitoring temperature is fixed on the inner wall of the extraction tank, and a PID controller for signal transmission connection with the platinum resistance temperature sensor is fixed on the outer side of the extraction tank.
[0007] Furthermore, the low-temperature cavity and the medium-temperature cavity are respectively provided with heat-insulating baffles fixed to the inner wall of the extraction tank on the side where they are close to each other, and the medium-temperature cavity and the high-temperature cavity are respectively provided with heat-insulating baffles fixed to each other. A set of resistance heating wires are coiled inside the low-temperature cavity, the medium-temperature cavity and the high-temperature cavity as heat sources, and the outer sides of the low-temperature cavity, the medium-temperature cavity and the high-temperature cavity are filled with heat-insulating rock wool to reduce heat loss to the environment.
[0008] Furthermore, a drive motor is fixed to the top of the extraction tank via a flange, and a stirring shaft extending into the extraction tank is coaxially fixed to the bottom of the output shaft of the drive motor. Multiple sets of blades arranged longitudinally are fixed to the outside of the stirring shaft, and the inclination angle of the multiple sets of blades increases sequentially from top to bottom as they pass through the low-temperature cavity, the medium-temperature cavity, and the high-temperature cavity.
[0009] Furthermore, the bottom of the mounting platform is fixed with multiple support legs arranged in a matrix, and the same connecting rod is fixed on the side of two adjacent support legs that are close to each other.
[0010] Furthermore, a liquid pump is fixedly installed on the top of the mounting platform. The input end of the liquid pump is sealed and connected to a suction tube for extracting external solutions that have damaged the cell walls of Chinese herbal medicines. The output end of the liquid pump is sealed and connected to an inlet pipe that is sealed and connected to the inside of the extraction tank.
[0011] In this application, when the device is working, the herbal material that has undergone cell wall disruption is first sent into the extraction tank through the pump and the inlet pipe. The drive motor drives the stirring shaft to rotate, and the blades on the shaft at different inclination angles produce differentiated stirring effects. The resistance heating wires in the low temperature cavity, medium temperature cavity and high temperature cavity are heated respectively. The temperature is detected by the platinum resistance temperature sensor. The PID controller independently adjusts the temperature of each area to keep the upper part low temperature, the middle part medium temperature and the lower part high temperature. The heat insulation ring reduces heat transfer between areas and the heat insulation rock wool reduces heat loss. After extraction is completed, the extract is discharged through the bottom valve of the tank.
[0012] In this utility model, the herbal medicine extraction device for food processing that is both food and medicine uses a zoned temperature control method to allow the effective components with different boiling points and heat sensitivity in the medicinal materials to dissolve at their respective suitable temperatures, thus avoiding the destruction of active ingredients by high temperatures. Differential stirring design ensures suitable fluid motion at different temperature levels, improving mass transfer efficiency. Thermal insulation reduces thermal interference between zones, enhancing temperature control accuracy. The overall structure is simple and reliable, and operation and maintenance are convenient, effectively improving extraction efficiency and product quality. Attached Figure Description

[0020] The drive motor 7 is fixed to the top of the extraction tank 3 via a 316 stainless steel flange. The flange and the tank cover are sealed with a polytetrafluoroethylene-coated asbestos gasket. The motor output shaft is connected to the stirring shaft 12 via a stainless steel rigid coupling. The stirring shaft 12 is a solid 316 stainless steel shaft with a polished surface. Multiple sets of blades 13 are welded onto the stirring shaft 12. The blades 13 are stamped from 316 stainless steel plates. The upper blade 13 has an inclination angle of 30 degrees, the middle blade 13 has an inclination angle of 45 degrees, and the lower blade 13 has an inclination angle of 60 degrees. The segmented stirring matches the extraction requirements of different temperature layers. All welds are polished.
[0021] The pump 4 is a mechanically sealed stainless steel centrifugal pump, which is fixed on the mounting platform 1 by a stainless steel base. The pump input end is connected to the silicone suction pipe 5 by a quick-release clamp, and the output end is connected to the liquid inlet at the top of the extraction tank 3 by a stainless steel corrugated pipe.
