Detailed ways

Embodiments of the invention are described in detail below. It is to be understood that the following description is only illustrative, and is not intended to limit the scope of the invention.

Referring to Figure 1, the liquid preparation apparatus includes a steam generator 1, a liquid storage container 2, and a material container 3.

The material container 3 is used to hold materials such as medicinal materials or ingredients.

The material container 3 is connected to the liquid storage container 2 for material and energy transfer with the liquid storage container 2. One form of connection of the material container 3 to the liquid storage container 2 is as follows: the material container 3 is placed in the liquid storage container 2, the material container 3 is provided with an opening 301 for opening the chamber 30 of the material container 3 with the liquid storage The chamber 20 of the container 2 is in communication such that the material container 3 can transfer material and energy to the liquid storage container 2 through the opening 301, including liquids, solids and gases, such as nutrients, steam, solvents and solutions. For the position of the opening 301, as long as the liquid storage container 2 and the material container 3 are subjected to material and energy transfer, for example, the substance in the liquid storage container 2 can enter the material container 3 through the opening 301, and the substance in the material container 3 can also It enters the liquid storage container 2 through the opening 301.

The steam generator 1 is used to supply steam to the material container 3. The steam generator 1 generates steam after it is operated, and the steam generator 1 delivers the steam to the material container 3 to distill the material to prepare a solution. One way in which the steam generator 1 supplies steam to the material container 3 is through a pipe.

Referring to Figures 1 and 17, the working process of the liquid preparation apparatus of the present invention and the liquid preparation method will be described below:

S200, distilling the material: placing the material in the material container 3, and then placing the material container 3 in the liquid storage container 2, the steam generator 1 starts to work, generates steam, and the steam enters the material container 3 to carry out the material. Distilling, the nutrient component is taken out of the material. Since the material container 3 is placed in the liquid storage container 2, the opening 301 of the material container 3 is in communication with the liquid storage container 2, and the nutrient component is directly dissolved in the liquid storage container 2. In the solution, at the same time, the steam contacts the solution in the liquid storage container 2, and the heat is transferred to the solution, and the temperature of the solution rises, so that the solution dissolves the nutrient component better.

S300, soaking the material: after the distillation is performed for a set period of time, the steam generator 1 stops generating steam, the material container 3 starts to cool, and the material container 3 generates a negative pressure. The opening 301 of the material container 3 is in communication with the liquid storage container 2. Under the action of the negative pressure, the solution in the liquid storage container 2 is quickly reversed to the material container 3 to form a high-pressure water column, and the material is impacted and stirred, and then The material is immersed so that more active ingredients of the material are dissolved in the solution.

After soaking for a set period of time, the steam generator 1 begins to generate steam again, and the steam enters the material container 3 to distill the material. After the distillation is completed, the steam generator 1 stops generating steam, and the solution in the liquid storage container 2 soaks the material. The distillation and soaking in such a plurality of cycles, such as two, three, four, five or six times, can complete the preparation of the liquid. Of course, according to actual needs, it is also possible to carry out only one distillation and soaking of the material, and the invention is not limited thereto.

Referring to FIG. 18, for some materials, such as Chinese medicine, step S100 is further included before step S200.

S100, infiltrating the material: before the material is distilled, some materials have a small amount of nutrients, such as protein and starch, which are soluble in water at low temperature and can not be separated in the material at high temperature, such as protein and starch. Removal, will be solidified on the surface of the material during the subsequent high-temperature distillation process, hinder the extraction of other nutrients, and infiltrate the material in advance to contact the part of the material with low-temperature water to dissolve the nutrients in the water to prevent This part of the material affects the expansion, and the material is infiltrated in advance to facilitate the expansion of the material. After the infiltration is completed, the water in the liquid storage container 2 dissolves the nutrient component of the material into a solution.

One way of achieving the infiltration is to place the material in the material container 3, inject a solvent such as water or an essence into the liquid storage container 2, and then place the material container 3 in the liquid storage container 2, in the liquid storage container 2 The water enters the material container 3 through the opening 301 of the material container 3 to come into contact with the material, thereby infiltrating the material.

According to the above, since the material container 3 is placed in the liquid storage container 2, the opening 301 of the material container 3 is in communication with the liquid storage container 2, that is, the material container 3 and the liquid storage container 2 are directly connected, and it is not necessary. By pipe connection, in the distillation, the nutrients are directly dissolved in the solution in the liquid storage container 2, without passing through the pipeline, so that the dissolution of nutrients is more timely and effective, thereby improving the efficiency of liquid preparation; No need for pipes, avoiding the accumulation of nutrients on the pipes and facilitating cleaning. The opening 301 of the material container 3 is in communication with the liquid storage container 2. When the chamber 30 of the material container 3 generates a negative pressure during the distillation, the liquid in the liquid storage container 2 is directly flowed back into the material container 3 without passing through the pipeline. Transmission, the liquid is less resistant, the flow rate is faster, and the material is impacted and stirred more quickly, which can better dissolve nutrients, improve the nutrient content of the solution, and improve the efficiency of liquid preparation. In addition, the steam in the material container 3 is also directly in contact with the solution in the liquid storage container 2, which reduces energy loss, makes full use of energy, makes the temperature of the solution rise faster, and also helps to improve the efficiency of liquid preparation.

The present invention is further described below:

Referring to FIG. 1, a liquid supply unit 6 for supplying liquid to at least one of the steam generator 1, the liquid storage container 2, and the material container 3 is further included.

The liquid supply unit 6 includes a liquid supply container 61, a flow rate sensor 62, and a switching valve 63. The liquid supply container 61, the flow rate sensor 62, and the switching valve 63 can form a main flow path 610, and the liquid in the liquid supply container 61 can flow to the steam through the main flow path 610. At least one of the generator 1, the liquid storage container 2, and the material container 3.

The flow sensor 62 is used to measure the flow rate of the liquid flowing out of the liquid supply container 61. If there is flow, the flow sensor 62 may display information, which may be a reading, a pointer rotation or a sound or the like.

The switching valve 63 is used to control the flow of the liquid in the liquid supply container 61. For example, the opening and closing valve 63 is opened, and the liquid in the liquid supply container 61 is discharged; the opening and closing valve 63 is closed, and the liquid stays in the liquid supply container 61.

Specifically, the main flow channel 610 can have different forms. For example, referring to FIG. 1, the liquid supply container 61 is first connected to the flow sensor 62, and then the flow sensor 62 is further connected to the switch valve 63, and the switch valve 63 is opened, if liquid flows out, The flow sensor 62 displays information; referring to Fig. 2, or the liquid supply container 61 is first connected to the switch valve 63, then the switch valve 63 is connected to the flow sensor 62, the switch valve 63 is opened, and if the liquid flows out, the flow sensor 62 displays information. .

According to the above, the flow of the liquid in the liquid supply container 61 is controlled by the opening and closing valve 63, and the flow rate of the liquid flowing out of the liquid supply container 61 is measured by the flow rate sensor 62, so that it is possible to know whether or not there is liquid in the liquid supply container 61. The distinction is whether the liquid supply unit 6 is faulty or the liquid in the liquid supply unit 6 has been used up, which is convenient to use.

Based on the above, the present invention is described in detail:

Referring to Fig. 3, the liquid supply unit 6 supplies liquid to the steam generator 1 and the material container 3, and the liquid supply container 61, the flow rate sensor 62, and the switching valve 63 are sequentially connected. The number of the liquid supply container 61 and the flow rate sensor 62 is one, and the number of the switching valves is two, which are the switching valve 63A and the switching valve 63B, respectively. The liquid supply container 61 is first connected to the flow rate sensor 62, and then the flow rate sensor 62 is again connected to the switching valve 63A and the switching valve 63B, respectively.

Referring to FIG. 3, the liquid supply container 61, the flow sensor 62, and the switching valve 63A form a first flow path 610A for supplying the liquid to the steam generator 1. The liquid supply container 61, the flow sensor 62, and the switching valve 63A may be connected by a pipe or may be directly connected together. The switch valve 63A can be connected to the steam generator 1 through a pipe to transport the liquid, or directly to the steam generator 1. For example, referring to FIG. 16, after the switch valve 63A is opened, the liquid flows under gravity to the switch valve. In the steam generator 1 below 63A, of course, the steam generator 1 is correspondingly provided with a valve through which the liquid flows into the steam generator 1 when the valve is opened.

Similarly, the liquid supply container 61, the flow sensor 62, and the switching valve 63B form a second flow path 610B for supplying liquid to the material container 3. The liquid supply container 61, the flow sensor 62, and the switching valve 63B may be connected by a pipe or may be directly connected together. The switch valve 63B can be connected to the material container 3 through a pipe to transport the liquid, or directly flow the liquid into the material container 3. For example, after the switch valve 63B is opened, the liquid flows under gravity to the material container 3 located below the switch valve 63B. .

Referring to FIG. 3, since the material container 3 is placed in the liquid storage container 2, the material container 3 is provided with an opening 301 which allows the chamber 30 of the material container 3 to communicate with the chamber 20 of the liquid storage container 2, thus When the liquid unit 6 adds liquid to the material container 3, the liquid in the material container 3 can flow into the liquid storage container 2 through the opening 301, thereby realizing the addition of liquid to the liquid storage container 2.

As described above, the liquid supply container 61, the flow rate sensor 62, and the switching valve 63 are sequentially connected. Thus, it is possible to know whether or not there is liquid in the liquid supply container 61 by the one flow rate sensor 62, which simplifies the structure and reduces the cost.

Referring to Figure 4, another form of connection of the material container 3 to the liquid storage container 2 is that the liquid storage container 2 is connected to the material container 3 through a pipe.

The liquid supply unit 6 supplies liquid to the steam generator 1, the liquid storage container 2, and the material container 3.

The liquid supply container 61 is first connected to the switching valve, and then the switching valve is connected to the flow sensor. Correspondingly, the number of the switching valves is three, which are the switching valve 63A, the switching valve 63B and the switching valve 63C; the number of the flow sensors is three, which are the flow sensor 62A, the flow sensor 62B and the flow sensor 62C, respectively.

The liquid supply container 61, the opening and closing valve 63A and the flow rate sensor 62A form a first flow path 610A for supplying liquid to the steam generator 1; the liquid supply container 61, the opening and closing valve 63B and the flow rate sensor 62B form a second flow path 610B for The liquid storage container 2 supplies the liquid; the liquid supply container 61, the opening and closing valve 63C, and the flow rate sensor 62C form a third flow path 610C for supplying the liquid to the material container 3.

The present invention has been described above, but the present invention may also have some modifications, such as:

Referring to Fig. 5, there is further included a liquid pump 64 disposed between the switching valve 63 and the liquid supply container 61 for pressurizing the liquid flowing out of the liquid supply container 61 to flow the liquid to a different place.

Based on the above, the present invention is further described:

Referring to Figure 6, there is further included a gas supply unit 7 for supplying gas to the material container 3. Since the material container 3 is in communication with the liquid storage container 2, the liquid in the material container 3 can be discharged into the liquid storage container 2 under the action of air pressure.

Due to the presence of the gas supply unit 7, correspondingly, the liquid preparation method can be realized as follows:

After the immersion is completed, gas is supplied to the material container 3 through the air supply unit 7 to discharge the liquid in the material container 3 to the liquid storage container 2 under the action of air pressure. The significance of this is that after the immersion is completed, the distillation needs to be continued, but at this time, the material is immersed in the liquid, and the liquid is discharged from the material container 3 through the gas supply unit 7, so that the material can be quickly exposed to the liquid surface and contact with the steam, and then distilled. . In addition, after the immersion is completed, the entire liquid preparation process is completed, and it is necessary to use the liquid in the material container 3, and the liquid is discharged from the material container 3 to the liquid storage container 2 through the air supply unit 7, which is convenient for use.

Specifically, referring to FIG. 6, the air supply unit 7 includes an air pump 71 and a check valve 72.

The check valve 72 is connected to the air pump 71. The air pump 71 is for generating a gas, and the check valve 72 is for preventing the gas from flowing back into the air pump 71. The air pump 71 delivers gas into the material container 3 through the one-way valve 72.

Referring to Figure 7, based on the steam generator 1 being able to supply steam to the material container 3, the gas supply unit 7 can also supply gas to the material container 3 via the steam generator 1. This is achieved in that the one-way valve 72 is hermetically connected to the steam generator 1 for conveying gas to the steam generator 1, which in turn delivers the gas to the material container 3.

Referring to Figure 7, a first switching valve 41 can also be provided, through which the steam generator 1 is hermetically connected to the material container 3. The first switching valve 41 is opened to deliver gas to the material container 3. Of course, the gas here includes the steam generated by the steam generator 1, and also the gas generated by the air pump 71.

Referring to Fig. 7, a cooling unit 8 for cooling the liquid in the liquid storage container 2 may also be provided. For example, after the liquid preparation is completed, the temperature of the liquid in the liquid storage container 2 is relatively high, and the liquid is cooled by the cooling unit 8 to conveniently use the liquid; when the immersion is performed, after the material container 3 is cooled, the liquid storage container 2 is The solution will be poured back into the material container 3 to soak the material, and the liquid in the liquid storage container 2 is cooled by the cooling unit 8. Due to the heat transfer, the cooling of the material container 3 can be accelerated to a certain extent, thereby accelerating the soaking. process.

The invention can also be implemented as follows:

Referring to Figure 8, the upper portion of the material container 3 is provided with a shower 31 for spraying liquid into the chamber 30 of the material container 3. The sprayer 31 sprays a liquid which is advantageous for preparing a solution, such as for cooling a material or for infiltrating a material, which may be water or an essence.

The shower 31 is connected to the liquid supply unit 6, and the liquid supplied from the liquid supply unit 6 is sprayed into the chamber 30 of the material container 3.

The shower 31 is provided, and step S300 is implemented as follows:

After the completion of the infiltration, the material is distilled. After the distillation is carried out for a period of time, the steam generator 1 stops supplying steam to the material container 3. Since there is no air in the material container 3, all of it is steam, and at this time, the material is passed through the shower 31. The steam in the container 3 is sprayed, and the steam in the material container 3 will be rapidly cooled in a moment after encountering the spray liquid, and at the same time, the solution in the liquid storage container 2 will also be quickly returned to the material container 3, When the solution reaches the material container 3, it will produce cold boiling. When it is boiled coldly, it will produce countless small bubbles in the solution of the material container 3. These small bubbles are very small in size, due to the existence of these very small small bubbles. Therefore, these small bubbles will easily enter the inside of the material immersed in the solution, and the small bubbles entering the inside of the material will burst inside, causing the effect of tearing the material to achieve a momentary or rapid expansion of the material.

The effect of generating cold boiling is that at the moment when the vacuum negative pressure is formed, the solution in the liquid storage container 2 is just returned to the material container 3, and at the moment of spraying, small bubbles are instantaneously generated, and then disappear instantly, and the cold boiling phenomenon occurs. End; it should be emphasized that the instant of spraying does not condense all the steam remaining in the material container 3, and will retain a part of it. It is this small part that causes the generation of small bubbles, which are not small bubbles. The air trapped in the liquid storage container 2 is not the air previously dissolved in the solution, and the small air bubbles are the residual steam in the material container 3. At the moment when the solution in the liquid storage container 2 flows back into the material container 3, the residual steam will not be diffused in the future, and will temporarily remain in the solution in contact with it instantaneously, and evenly distributed, the quantity is large, and the size is small, resulting in After the small bubbles come into contact with the solution, they will be condensed by the solution, so they will disappear instantly. It is this process that has an instant puffing effect on the material.

After the cold boiling, the spray has stopped at this time, since the negative pressure in the material container 3 is generated instantaneously, the solution in the liquid storage container 2 will continue to backflush back into the material container 3, in the process of backflow, A water column will be formed in the material container 3, and the generated water column will stir and churn the liquid retained in the material container 3, thereby impacting and tumbling the material in the material container 3 to agitate, and the rapid high pressure The impact type agitation is more balanced than the general agitation such as chopsticks and reamer, so as to achieve no-knife agitation of the material; plus the material has been expanded in a cold boiling for a moment, plus this rapid high-pressure impact type Stirring, the water-soluble, volatile and other nutrients in the material will dissolve.

During the whole process of preparing the liquid: the steam in the distillation will slowly condense and slowly puff the material, which is the initial stage of expansion; after the material is torn and expanded by cold boiling, the material is further Fluffy, this is the second stage of expansion; plus the backflushing water column formed by the negative pressure, the material's crack will further increase, which is the third stage of expansion; after the above expansion, the material is already fluffy, the crack is enlarged And increase, it will make it easier for the solution to enter the material to dissolve the water-soluble active ingredient. After the final immersion solution, all the solution in the material container 3 is discharged into the liquid storage container 2, and the solution in the liquid storage container 2 contains not only the volatile components in the extracted material but also the water-soluble components. .

Of course, the liquid preparation method can be carried out once or in a repeated process, and the expanded material is also very favorable for the steam to enter the material to take away the volatile components in the next distillation process, and become the mixed steam dissolved in the storage. It is also very effective for extracting volatile components in the solution in the liquid container 2.

The shower 31 is a shower head. Referring to FIG. 9, the shower 31 may be sprayed in the form of a drop umbrella type 311, a drop direct type 312, a drip type 313, and a mist 314. The water droplet umbrella type 311 has the best effect and the fastest speed. For water with relatively high water temperature, it can be sprayed in this way, followed by water drop straight type, mist type and dripping type. For the low water temperature, this can be used. The way to spray.

The liquid preparation device of the present invention will be further described below:

In order to reduce steam loss, the steam generator 1 is hermetically connected to the material container 3. Referring to Figure 1, one way for the steam generator 1 to supply steam to the material container 3 is through a pipe, in particular, the steam generator 1 is hermetically connected to the material container 3 through the first pipe 4. Referring to Fig. 1, a sealing cover 33 can also be provided on the top of the material container 3, so that the material container 3 can be opened from the top, and the first pipe 4 can also be hermetically connected to the sealing cover 33, of course, also in the material container 3. A bottom cover (not shown) is provided at the bottom to open the material container 3 from the bottom.

Referring to Figure 1, a first switching valve 41 is provided on the first conduit 4. During the distillation, the steam generator 1 generates steam, the first switching valve 41 is opened, and the steam in the steam generator 1 enters the material container 3 to distill the material. During the soaking process, the steam generator 1 stops generating steam, and the first switching valve 41 is closed, which can speed up the cooling rate of the chamber 30 of the material container 3 and generate a stronger negative pressure.

Referring to Figures 10 and 11, a first valve 5 is also included, with the steam generator 1 being connected to the material container 3 via a first valve 5. Referring to Figure 10, the side wall of the steam generator 1 is attached to the side wall of the material container 3, and the first valve 5 connects the steam generator 1 with the material container 3; referring to Fig. 11, or the first valve 5 is disposed at The side wall of the steam generator 1 is between the side wall of the material container 3. During the distillation, the first valve 5 is opened and the steam in the steam generator 1 enters the material container 3 to distill the material. During the soaking process, the first valve 5 is closed.

Referring to Fig. 12, the material container 3 is placed in the liquid storage container 2, for example, the material container 3 is placed in the liquid storage container 2 from the upper portion of the liquid storage container 2, in order to prevent the vapor inside the liquid storage container 2 from the liquid storage container 2 The upper portion of the liquid storage container 2 is provided with an end cap 21, and the end cap 21 of the liquid storage container 2 is connected to the side wall of the material container 3. Of course, the material container 3 can also be placed in the liquid storage container 2 from the side of the liquid storage container 2, and the end cover 21 is also disposed on the side of the liquid storage container 2, which is not limited thereto.

Referring to Figure 13, the opening 301 is disposed in the lower portion of the material container 3, such as at the lower side.

Referring to FIG. 1, the opening 301 can also be disposed at the bottom of the material container 3, so that all the liquid in the material container 3 can be discharged into the liquid storage container 2, so that the material in the distillation process is in full contact with the steam to ensure the distillation effect, and Making full use of the negative pressure in the soaking process, the solution in the liquid storage container 2 enters the material container 3 from the bottom of the material container 3, and the material is sufficiently impacted and stirred from the bottom.

Referring to Figure 14, the material container 3 is provided with a screen 32 which is located on one side of the opening 301 for preventing material from entering the liquid storage container 2.

The number of openings 301 may be plural, such as two, three, four or more, so that a plurality of high pressure water columns may be formed during the soaking process. At the same time, the size of the opening 301 is smaller than the size of the material for blocking the material from entering the liquid storage container 2, and opening a plurality of openings 301 to form a filter net, which simplifies the structure.
