Description

Technical Field

[0001] The present invention relates to the technical field of botanical pesticides, and in particular to an industrialized continuous low-carbon production system and process for botanical pesticide raw materials. Background Art

[0002] While the use of chemical pesticides ensures increased production and harvests of grain, vegetables, and fruits, they also pose significant risks and hazards to organisms and the environment, directly endangering human health and lifespan. Biopesticides, particularly botanical pesticides, offer advantages such as low toxicity, low risk of resistance, natural degradation, relative safety for humans and animals, minimal damage to natural enemies of pests, low residue levels, the ability to maintain high agricultural product quality, and sustainable raw material production. They have become a major alternative to chemical pesticides and a growing trend in global agriculture. However, traditional prescription botanical pesticides also suffer from shortcomings such as slow onset of efficacy, short residual duration, complex formulations, difficulty in standardization, and seasonal plant collection. These challenges particularly concern the streamlining, standardization, and efficiency of production processes.

[0003] The traditional production process for prescription botanical pesticides involves compounding (based on the formula of the dried herbal remedy), soaking in water, boiling, filtering, and concentration. These processes generally lack precise control over the active ingredients. Furthermore, Chinese herbal medicines are susceptible to biochemical changes during harvesting and drying, particularly during sun-drying and air-drying. This leads to a loss of active ingredients, particularly inactivation of active substances and decay, which reduces yield. Furthermore, during high-temperature boiling, a significant amount of active substances is decomposed and lost. This not only reduces efficacy, but also consumes significant energy during the drying, boiling, and concentration processes, limiting production capacity. The drying and boiling processes significantly reduce the active ingredients in the formulation due to factors such as enzymatic degradation, photodegradation, thermal degradation, and low extraction yields (dregs).

[0004] Therefore, the above-mentioned process, which was derived from traditional Chinese medicine decoction, has problems such as difficulty in controlling the efficacy of the medicine, high cost, and high energy consumption. It can no longer meet the needs of the development of botanical pesticides. It is urgent to provide a botanical pesticide production process that is suitable for large-scale, industrialized, standardized, low-carbon and efficient production and has a high content of effective ingredients. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide an industrialized continuous low-carbon production system and process for plant-based pesticide raw materials. Through freezing wall breaking, fresh squeezing and room temperature concentration processes, the effective ingredients and their activity in the plants are effectively retained, and large-scale low-carbon continuous production is achieved.

[0006] The technical solution of the present invention is:

[0007] On the one hand, the present invention provides an industrialized continuous low-carbon production system for plant-based pesticide raw materials, including A and B production lines arranged in parallel and facing each other, and both A and B production lines include a cleaning machine, a shredder, a pre-cooling heat exchange device, a freezing and wall-breaking device, a slow revival heat exchange device, a primary pressing device, a humidifying and stirring device and a secondary pressing device connected in sequence through a conveyor; the pre-cooling heat exchange device of production line A and the slow revival heat exchange device of production line B, as well as the slow revival heat exchange device of production line A and the pre-cooling heat exchange device of production line B are respectively connected with hot and cold convection air ducts to realize hot and cold air convection; the secondary pressing devices of production lines A and B are also connected in sequence with a solid material drying device and a wall-breaking grinder through conveyors, and the liquid material outlets of the primary pressing devices and the secondary pressing devices of production lines A and B are connected in sequence with an ultrafiltration device, a macromolecular filtration and concentration device and a raw material tank through pipelines.

[0008] Preferably, the pre-cooling heat exchange device, freezing wall breaking device, slow thawing heat exchange device and solid material drying device all include a multi-layer mesh belt conveyor, and a protective sealing mechanism is provided on the outside of the multi-layer mesh belt conveyor, and hot and cold convection air ducts are connected between the pre-cooling heat exchange device and the protective sealing mechanism of the slow thawing heat exchange device; the protective sealing mechanism of the freezing wall breaking device is also connected to a refrigerator through a pipeline; a heat recovery air duct is connected between the refrigerator and the protective sealing mechanism of the solid material drying device, and a heat pump is provided on the heat recovery air duct.

[0009] Preferably, the enclosure sealing mechanism includes sealing plates arranged around and on the top of the multi-layer mesh belt conveyor, a feed port is provided on the top sealing plate, and a discharge port is provided on one of the surrounding sealing plates.

[0010] Preferably, both the primary pressing device and the secondary pressing device are screw presses.

[0011] Preferably, the humidifying and stirring device includes an auger, which is provided with a feed inlet, a water inlet and a discharge port, and the water inlet is connected to a liquid storage tank through a pipeline.

[0012] Preferably, a dispersion tank 1 is connected between the ultrafiltration device and the macromolecular filtration and concentration device, and a dispersion tank 2 is connected between the macromolecular filtration and concentration device and the raw material tank. The dispersion tank 1 and the dispersion tank 2 are respectively connected to a nitrogen filling pipe and a drug dosing pipe.

[0013] Preferably, a coarse filtration device is connected between the first-stage pressing device, the second-stage pressing device and the ultrafiltration device through a pipeline. The ultrafiltration device uses silicon carbide or ceramic organic hollow fiber with a permeability of less than 0.2um. The macromolecular filtration and concentration device uses DTR0 with an interception pore size of ≤0.4nm.

[0014] On the other hand, the present invention also provides a process for the industrialized continuous low-carbon production of botanical pesticide raw materials by the above-mentioned production system. The A and B production lines run simultaneously in opposite directions, and the materials are successively cleaned, chopped, pre-cooled and heat-exchanged, frozen and broken, slowly thawed and heat-exchanged, first-stage pressed, solid material humidified and stirred, and second-stage pressed. The solid material after the second-stage pressed is successively dried and ground to obtain solid raw materials; the liquid materials produced by the first-stage pressing and the second-stage pressing are successively ultrafiltered and molecularly filtered and concentrated to obtain liquid raw materials.

[0015] Preferably, when the solid material is humidified and stirred, the highly soluble small molecular cluster water treated by the overflow of the strong magnetically coupled terahertz material is used to dissolve and absorb the effective components in the solid material.

[0016] Preferably, the freezing wall breaking temperature is -3~-10°C, and the ultrafiltration and molecular filtration concentration temperature is -3~30°C.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In short, the present invention effectively retains the effective ingredients and their activity in plants through freeze-breaking, fresh squeezing and room temperature concentration processes, and realizes large-scale low-carbon continuous production through the production system of the present invention. The method of the present invention of first preparing monomer raw materials and then compounding can more accurately obtain the required effective ingredients from the production process, and is easy to prepare special medicines with precise effects on certain pests and diseases during compounding. It overcomes the problem that when the raw materials are first compounded and mixed before application, the efficiency is high against a certain pest and disease, but low against another pest and disease, and is ineffective against some pests and diseases, which brings waste of resources to downstream applications. The present invention can be widely used in industries such as botanical pesticides, health products, and foods, especially in the processing of some plant raw materials with high hardness and high fiber content.

[0019] 2. Freeze-wall breaking and fresh squeezing are important processing steps of the present invention. The materials processed in the present invention are freshly harvested roots, stems, leaves, branches, flowers, fruits, and seeds of Chinese herbal medicines, woody or herbaceous plants rich in insecticides, bactericides, and virus-inactivating substances. After freeze-wall breaking, they are freshly squeezed to obtain alkaloids, glycosides, toxic proteins, volatile essential oils, tannins, organic acids, phenols, esters, aldehydes, amines, and the like in the Chinese herbal medicines. The slow freezing (i.e., pre-cooling and freeze-wall breaking) of the fresh materials by the present invention causes ice crystals to form in the intercellular spaces. The cell walls are destroyed by the ice crystals, causing the continuous outflow of intracellular water and the rapid death of cell tissue, locking in the effective ingredients and preventing metabolic and biochemical loss. In addition, the present invention also improves the permeability between the cell tissue of the medicinal material and the juice on the surface of the body through slow freezing, significantly increasing the juice extraction rate.

[0020] 3. This invention utilizes a three-step process: pre-cooling and heat exchange → freezing and cell wall breaking → slow thawing and heat exchange. This scientifically and ingeniously achieves slow freezing and cell wall breaking, effectively increasing juice yield, achieving energy conservation and low carbon emissions, and significantly reducing cold energy consumption. Furthermore, this invention performs macromolecular separation, filtration, and concentration on the squeezed liquid material at room temperature (or low temperature). This not only preserves the active ingredients of the medicinal solution, but also offers significant advantages over distillation, with higher efficiency, lower energy consumption, and lower costs.

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0028] Example 1

[0029] like Figure 1-2 As shown, this embodiment provides an industrialized continuous low-carbon production system for botanical pesticide raw materials, including A and B production lines arranged in parallel and facing each other, and both A and B production lines include a cleaning machine 1, a chopper 2, a pre-cooling heat exchange device 3, a freezing wall breaking device 4, a slow thawing heat exchange device 5, a primary pressing device 6, a humidifying and stirring device 7, and a secondary pressing device 8, which are sequentially connected through a conveyor 19 (such as an auger screw elevator). Figure 4 As shown, the secondary pressing device 8 is also connected to the solid material drying device 10 and the wall-breaking mill 11 in sequence through the conveyor 19, as shown in FIG. Figure 3 As shown, the liquid material outlets of the first-stage pressing device 6 and the second-stage pressing device 8 are connected to the ultrafiltration device 12, the macromolecular filtration and concentration device 13 and the raw material tank 14 in sequence through pipelines. The production system of the present invention sequentially washes the fresh plant products → chops → pre-cooling and heat exchange → freezing and breaking the wall → slow thawing and heat exchange → first-stage pressing residue liquid separation → humidification and stirring → second-stage pressing residue liquid separation, and then performs liquid material ultrafiltration → macromolecular filtration separation and concentration to obtain plant-derived pesticide monomer raw materials, which can be subsequently compounded into a special medicine for certain diseases and insect pests; and the solid material after the second-stage pressing is dried and ground into powder, which can be compounded with the powder raw material. After freezing and breaking the wall, the starch in the medicinal material solidifies, the protein denatures, and most of the sugar remains in the medicinal residue. Therefore, the processed powder contains more organic fertilizer components, which better plays the role of both medicine and fertilizer.

[0030] Specifically, the pre-cooling heat exchange device 3, the freezing wall breaking device 4, the slow thawing heat exchange device 5 and the solid material drying device 10 all include a multi-layer mesh belt conveyor 2001, wherein Figure 1As shown, the pre-cooling heat exchange device 3, the freezing wall breaking device 4 and the thawing and recovering heat exchange device 5 all adopt five-layer mesh belt conveyors 19, and the solid material drying device 10 adopts three-layer mesh belt conveyors 19, and the mesh belt material can adopt stainless steel or engineering plastic, such as SUS304, ABS engineering plastic and the like. The multi-layer mesh belt conveyor 2001 is externally provided with an enclosure sealing mechanism 2002, and the enclosure sealing mechanism 2002 comprises sealing plates arranged around and on the top of the multi-layer mesh belt conveyor 2001, the sealing plate on the top is provided with a feeding port, and one of the sealing plates around is provided with a discharging port. In order to further reduce the heat exchange between the inside and outside of the enclosure sealing mechanism 2002, heat insulation curtains can be arranged at the feeding port and the discharging port of the sealing plate.

[0031] The size of the space surrounded by the enclosure sealing mechanism 2002 is 102m*3m*6m, and the sealing plate can adopt a PU stainless steel sandwich composite plate with a thickness of 1mm+100mm+1mm. In the multi-layer mesh belt conveyor 2001, the single-layer specification is 100m*2.6m, the thickness of the material running on the mesh belt can be 30-250mm, and in the A or B production line, the weight of the material on the mesh belt is between 30-500kg / m, and the transmission running speed is 1-10m / min.

[0032] As shown in the figure, Figure 1 The freezing wall breaking device 4 is connected with a refrigeration machine 401 through a pipeline, and the power of the refrigeration machine 401 is designed according to the required cold energy of the material processing amount per unit time and the environmental working temperature. The temperature of the enclosure space of the freezing wall breaking device 4 is-3--10℃, and assuming that the freezing wall breaking temperature is-5℃, when the running speed of the multi-layer mesh belt conveyor 2001 is 3m / min, the residence time of the material in each interval of pre-cooling, freezing wall breaking and thawing and recovering is about 166min, that is, the time of pre-cooling and freezing wall breaking is about 332min (5.53h) in total. When the running speed of the multi-layer mesh belt conveyor 2001 is 3m / min, the thickness of the material is 10cm, and the weight of the material on the mesh belt is 200kg / m, the single-line yield of the A or B production line is 0.6T / min, and the A and B production lines can process fresh materials 72T / h, which is suitable for seasonal large-scale acquisition of tobacco straw, potato stems and the like for fresh processing.

[0033] In the present application, as shown in the figure, Figure 1As shown, the pre-cooling heat exchange device 3 of production line A and the slow thawing heat exchange device 5 of production line B, as well as the slow thawing heat exchange device 5 of production line A and the pre-cooling heat exchange device 3 of production line B are respectively connected with hot and cold convection air ducts 9, and the hot and cold convection air ducts 9 are connected between the pre-cooling heat exchange device 3 and the slow thawing heat exchange device 5 of the pre-cooling heat exchange device 3, so that the hot air in the enclosure space of the pre-cooling heat exchange device 3 of production line A can be used in the slow thawing heat exchange device 5 in production line B to thaw and thaw the materials, so that cold energy is saved; similarly, the cold air formed in the thawing process of the slow thawing heat exchange device 5 of production line B can be used for heat exchange with the normal temperature materials in the pre-cooling heat exchange device 3 of production line A to pre-cool the normal temperature materials, which just cooperates with the subsequent freezing wall breaking device 4 to achieve the slow freezing and wall breaking effect, avoiding the problem that the wall breaking effect cannot be achieved due to quick freezing.

[0034] Specifically, if Figure 2 As shown, the humidifying and stirring device 7 used in this embodiment includes an auger 701, which is provided with a feed port, a water inlet and a discharge port. The water inlet is connected to a liquid storage tank 702 through a pipe, and a valve is provided on the pipe. The solid material separated by the primary squeezing enters the auger 701 through the feed port, is mixed with the "small molecular cluster water" in the liquid storage tank 702, and then enters the secondary squeezing device 8 for a second squeezing out of the effective components therein. The addition amount of "small molecular cluster water" is 50-80% of the solid material.

[0035] Furthermore, a key process of this invention is concentration. The most common traditional concentration method is distillation. Traditionally, evaporating one ton of water theoretically requires 540,000 kcal of heat. Considering the heat efficiency, this is typically calculated at 600,000 kcal, equivalent to 720 kWh. At 1 yuan per kWh, evaporation and concentration costs 720 yuan per ton of water. The costs of MSF (Multi-Stage Flash Distillation) and MED (Mid-Temperature Multi-Effect Distillation) are likely lower. This not only consumes more energy, but also causes degradation and loss of liquid materials at high temperatures.

[0036] The present invention utilizes a molecular separation method for concentration. After two molecular separations, the ultrafiltration device 12 can utilize silicon carbide or ceramic organic hollow fibers with a permeability of less than 0.2 μm. The macromolecular filtration and concentration device 13 utilizes a DTR0 filter with an interception pore size of ≤0.4 nm, allowing only water molecules between 0.28 and 0.39 μm to pass through. The water that passes through is collected in a recovery tank 21 for reuse. The present invention utilizes room temperature (or low temperature) concentration, preserving many of the required active ingredients and their activity. In the ultrafiltration device 12, the pump pressure is 15 bar, the flow rate is 70 T / h, and the filter material used is silicon carbide with a pore size of 0.1 μm, resulting in a filtration area of ​​4 × 8 m2. 2 The interception rate of liquid materials such as walnut peel, stemona root, and sophora flavescens is between 10% and 15%, and the passing rate is between 90% and 85%.

[0037] Macromolecule filtration and concentration device 13 uses DT component 90bar×9.4m 2 ×30 (units), with a membrane pore size of 0.4nm, using a 9.5MPd plunger pump, a flow rate of 60 tonnes / hour, an interception rate of 20-25%, a pass rate of 75-80%, and effluent COD <5mg / L. The macromolecular concentrate from the primary separation is mixed with the macromolecular concentrate from the secondary separation. Assuming an interception rate of 10% for the ultrafiltration device 12 and a 30% interception rate for the macromolecular filtration and concentration device 13, 25 tonnes / hour of botanical pesticide concentrate can be produced. For example, the tobacco straw concentrate can achieve a nicotine content of ≥0.28%, fully meeting the required specifications for biopesticides.

[0038] When separating and concentrating the squeezed liquid material, Figure 3 As shown, depending on the type of material, dispersion tank 15 can be connected between ultrafiltration device 12 and macromolecular filtration and concentration device 13, and dispersion tank 2 16 can be connected between macromolecular filtration and concentration device 13 and raw material tank 14. Dispersion tank 15 and dispersion tank 2 are respectively connected to nitrogen filling pipe 1701 and chemical dosing pipe 1801. Nitrogen filling pipe 1701 is connected to nitrogen storage tank 1702, and chemical dosing pipe 1801 is connected to chemical storage tank 1802. Depending on the type of material, different chemical agents can be added to dispersion tank 15 and dispersion tank 2 16. For example, inorganic acids, organic acids, or alkaline substances can be added to form salts, which then precipitate and extract a high concentration of a single active ingredient. Adding chemical and concentrating liquid materials under nitrogen filling conditions can extract a single active ingredient, resulting in a higher content of the active ingredient.

[0039] In addition, a coarse filtration device (such as a DN2000×6000 quartz sand filter) can be connected between the first-stage pressing device 6, the second-stage pressing device 8 and the ultrafiltration device 12 through a pipeline. The squeezed liquid material first passes through the coarse filtration device to filter out solid impurities therein, and then enters the subsequent ultrafiltration device 12 for separation and concentration.

[0040] The residue squeezed out after the secondary pressing process enters the multi-layer mesh belt conveyor 2001 of the solid material drying device 10 for drying. After drying, the moisture content is ≤14%. It then enters the wall-breaking mill 11 and is ground into a 100-300 mesh powder. Fermentation with bacterial strains can be added as needed, which not only has a certain effect on root pests and diseases but also has a high fertilizer effect. For example, tobacco contains approximately 10% crude protein, monosaccharides, starch, and fat, making it highly effective as a fertilizer.

[0041] The heat source of the solid material drying device 10 in the application can be a heat pump or a clean solar energy source, a heat recovery air conveying pipe is connected between the refrigerating machine 401 and the enclosure sealing mechanism 2002 of the solid material drying device 10, and a heat pump 1001 is arranged on the heat recovery air conveying pipe, so that the hot air discharged from the refrigerating machine 401 is conveyed into the enclosure sealing mechanism 2002 of the solid material drying device 10 through the heat pump 1001, and is used for heating and drying the solid material, thereby fully embodying the energy-saving and low-carbon design.

[0042] In the industrialized continuous low-carbon production process of the plant source pesticide raw material of the application, the processing process is divided into two solid-liquid processing routes, liquid agents and powders are finally prepared, and almost all effective components are retained, and there is almost no waste, and the so-called waste of effective components is organic matter contained in the discharged water. The liquid agent can be used as a pesticide raw material, and the powder formed after the drug residue after solid-liquid separation is dried and ground can be used as a raw material of an organic pesticide fertilizer, and can be used in base fertilizer after compounding, thereby realizing the dual effects of pesticide and fertilizer.

[0043] Example 2

[0044] In the broken wall fresh squeezing process of the application, fresh squeezing is an important process. Common squeezing devices include reciprocating squeezing machines, stick squeezing machines and belt filter squeezing machines, but they are not suitable for squeezing of materials with high hardness and many fibers, such as tobacco straw, sophora flavescens and fish poison root branches and leaves, and the liquid yield is extremely low or even no water can be squeezed out. The first-stage squeezing device 6 and the second-stage squeezing device 8 of the application both adopt screw squeezing machines, which are the only squeezing mode with continuous operation, large extrusion force and high liquid yield among all the squeezing modes at present. The frequency conversion motor of the two screw squeezing machines in the embodiment has a rated power of 200 kW, and the extrusion screw has a specification of ∮400mm*3600mm. For processing and squeezing of high-fiber and hard plant roots such as tobacco straw roots, sophora flavescens and fish poison roots, the squeezing capacity is greater than or equal to 1T / min, and the liquid yield is higher than that of reciprocating squeezing machines, stick squeezing machines and belt filter squeezing machines.

[0045] For example, fresh tobacco straw (containing part of defective tobacco leaves), the liquid yield of the fresh tobacco straw squeezed by the screw squeezing machine at room temperature is 28-30%, the liquid yield of the fresh tobacco straw squeezed by the reciprocating squeezing machine is 13%, and the liquid yield of the fresh tobacco straw squeezed by the screw squeezing machine after the pre-cooling heat exchange, frozen broken wall and slow recovery heat exchange process of the application is 73-81%.

[0046] The liquid yield of sophora flavescens squeezed by the reciprocating squeezing machine at room temperature is less than 3%, the liquid yield of sophora flavescens squeezed by the screw squeezing machine is less than 9%, and the liquid yield of sophora flavescens squeezed by the screw squeezing machine after the pre-cooling heat exchange, frozen broken wall and slow recovery heat exchange process of the application is 67%.

[0047] At room temperature, the liquid yield of the poisonous fish vine after being squeezed by a reciprocating press is less than 2%, and the liquid yield after being squeezed by a screw press is less than 7%. However, after the pre-cooling heat exchange, freezing wall breaking, and slow thawing heat exchange steps of the present invention, the liquid yield after being squeezed by a screw press in the first stage is 51%, and the liquid yield after being squeezed in the second stage is 79%.

[0048] In addition, in order to squeeze out more effective ingredients during the secondary squeezing, the present invention first uses high-solubility "small molecular cluster water" treated with strong magnetic coupling terahertz material to humidify and stir the solid material squeezed out of the first stage, quickly dissolving and absorbing the effective ingredients in the solid material to facilitate subsequent secondary squeezing, and the squeezing effect is much higher than that of ordinary water. Among them, "small molecular cluster water" is ordinary pure water that is first magnetized and then subjected to a frequency of 10 12 The terahertz electromagnetic wave of HZ irradiates water, breaking the approximately 10 hydrogen bonds of the longer and larger water molecule clusters into 5-6.

[0049] Ordinary pure water was used to mix and humidify the solid tobacco straw material after the first-stage pressing. The nicotine content in the liquid material after the second-stage pressing was tested to be 180 mg / L. When an equal amount of the above-mentioned highly soluble "small molecular cluster water" was used, the nicotine content in the liquid material after the second-stage pressing was tested to be 670 mg / L, which is 3.7 times that of ordinary pure water.

[0050] Example 3

[0051] After sampling and testing, after the tobacco straw was treated by the process of Example 1 of the present invention, the nicotine content in the liquid material was 0.11%, accounting for 89% of the total nicotine content in the tobacco straw, and the nicotine in the solid material (i.e., the medicinal residue) accounted for 11% of the total nicotine content in the tobacco straw; the nutrients such as starch and protein in the liquid material accounted for 9% of the total nutrients in the tobacco straw, and the nutrients in the medicinal residue accounted for 91% of the total nutrients in the tobacco straw.

[0052] After the Sophora flavescens is treated by the process of the present invention, the total alkali content in the liquid material is 0.17%, accounting for 89% of the total alkali content in the Sophora flavescens, and the total alkali content in the medicinal residue accounts for 11% of the total alkali content in the Sophora flavescens; the nutrients in the liquid material account for 8% of the total nutrients in the Sophora flavescens, and the nutrients in the medicinal residue account for 92% of the total nutrients in the Sophora flavescens.

[0053] After the ichthyophthirius is treated by the process of the present invention, the rotenone in the liquid material accounts for 86% of the total rotenone in the ichthyophthirius, and the rotenone in the medicinal residue accounts for 14% of the total rotenone in the ichthyophthirius; the nutritional components in the liquid material account for 92% of the total nutritional components in the ichthyophthirius, and the nutritional components in the medicinal residue account for 8% of the total nutritional components in the ichthyophthirius.

[0054] In summary, the industrial continuous low-carbon production equipment and process of botanical pesticide raw materials of the present invention fully embodies energy saving, low carbon, continuous and efficient production, and the juice and residue are fully utilized after separation during squeezing, retaining all the nutritional activity of the botanical medicinal materials, without generating three wastes, and being environmentally friendly, providing new equipment and processes for the industrial large-scale continuous production of botanical pesticides and Chinese herbal medicine preparations.
