Description

Technical Field

[0001] The utility model relates to a natural flavor extraction device, in particular to a leaching device for crushed materials. Background Art

[0002] Solvent extraction is one of the most common methods for obtaining natural spices. Solvent extraction of materials in an extraction tank has the advantages of simple method, low equipment requirements, low technical difficulty, and easy cost control.

[0003] In industrial production, materials used for extraction are usually in the form of powder. Ordinary dry materials are easier to transport and store than wet materials such as fresh leaves and flowers. Before the extraction operation, the dry materials are crushed and then extracted to fully obtain the aroma components of the raw materials and improve the extraction efficiency. In addition, some materials, including tea leaves and waste cigarettes, exist in the form of powder. These powdered materials face many operational difficulties during the extraction process. One of the biggest problems is that the feeding and discharging time before and after the extraction is too long.

[0004] For the extraction of materials in a crushed state, the mixing process of the feed and liquid is slow when feeding, and sometimes the setting requires the feed and liquid to be fed alternately for multiple times, and the feeding time is lengthy. Moreover, this type of extraction usually adopts a relatively high material-liquid ratio (often the feed and liquid just cover the surface of the material after being put in), and the mechanical stirring resistance is too large and easy to be damaged, so there is a problem of uneven natural mixing of the material and the solvent or "solvent short circuit" during discharge. In addition, after the extraction of the crushed state is completed, the material is usually discharged naturally by gravity, and the filtration effect of the crushed material itself can be used to obtain the clear liquid of the material. However, this process is often time-consuming and inefficient. Even with physical stirring and pressurization operations, it is difficult to shorten the discharge time. The reason is that the lower end size of the ordinary vertical extraction tank is limited, and the separation area of ​​the material and liquid is insufficient. Therefore, in actual production, it is often necessary to use extrusion, centrifugation and other means to process the wet material to obtain the material liquid, which increases the cost and energy consumption. The use of a horizontal extraction tank can increase the separation area of ​​the material and liquid, which can alleviate these difficulties to a certain extent, but the effect is limited, and there are problems such as increased difficulty in operation, large floor space and insufficient space utilization. Therefore, the market needs new devices to improve production efficiency. Summary of the invention

DETAILED DESCRIPTION

[0015] The embodiments of the present utility model are further described below in conjunction with the accompanying drawings.

[0016] Embodiment 1

[0017] See also Figure 1-2 , this embodiment is composed of a tank body 1, an upper cover 2, and a lower cover 3. It is characterized in that the tank body 1 is connected to the upper cover 2 by a hinge. The tank body 1 is connected to the lower cover 3 through a cover opening device 13. The cover opening device 13 is a hydraulic pneumatic switch to control the opening and closing of the lower cover. An upper cover sealing buckle 10 and a lower cover sealing buckle 11 are respectively provided between the tank body 1 and the upper cover 2 and the lower cover 3. The upper cover and the lower cover opening are respectively provided with sealing rings. The upper cover 2 is provided with a feed port 8, an air flow valve 6, and a pressure gauge installation port 15. The air flow valve 6 on the upper cover 2 can increase the air pressure in the upper space when the extract is released by connecting to an external air pump, thereby further improving the liquid discharge speed. The upper cover 2 is provided with an upper cover handle 9. The interior of the lower cover 3 is a liquid storage chamber 12, the top of the lower cover 3 is provided with a stainless steel mesh surface, and the bottom of the lower cover 3 is provided with a number of support legs 5 and a liquid outlet valve 7. A thermometer installation port 14 is provided on the outer wall of the tank body 1. A drainage device 4 is provided in the tank body 1, a bracket 16 is provided at the bottom of the drainage device 4, and a plurality of drainage chambers 17 are fixed through a fixing port 18 on the bracket 16. The drainage chamber 17 is a 300-500 mesh stainless steel mesh structure, and the fixing port 18 of the bracket 16 is provided with a thread, and the drainage chamber 17 is fixed through the thread on the fixing port 18.

[0018] When in use, the leaching material and the solvent are put into the equipment of this embodiment, and the leaching is carried out using an extraction tank equipped with a drainage chamber 17. In the drainage device, the mesh structure of the drainage chamber 17 can effectively isolate the material. Compared with the ordinary leaching tank, the presence of the drainage chamber 17 increases the activity space of the solvent, so that the mixing time of the feed and liquid is shorter and more sufficient when feeding. During the discharge process, the presence of the drainage device 4 increases the contact area between the feed and the liquid by several times, and because the drainage chamber 17 has a certain height, the time for the upper part of the feed to flow out of the material is shortened, so the discharge speed is greatly improved, and the amount of feed and liquid obtained is also increased. Combined with means such as upper end pressurization, the separation of the feed and liquid can be further promoted, and the efficiency improvement effect is better.

[0019] The upper cover 2 is opened and closed manually by the handle 9. The upper cover 2 can keep the upper end of the extraction tank sealed by the sealing buckle 10. The lower cover 3 is opened and closed by the cover opening assembly 13. The bottom liquid outlet of the lower cover 3 is provided with a liquid outlet valve 7 to control the release of the liquid. The bracket 16 in the drainage device 4 plays a supporting and fixing role. Several threaded fixing ports 18 are distributed in the middle of the bracket. In this embodiment, there are seven. The fixing ports 18 are used to fix the drainage chamber 17. Each drainage chamber 17 can be disassembled and assembled separately. The drainage chamber 17 is a 300-500 mesh stainless steel structure. In this embodiment, it is a 500 mesh stainless steel structure.

[0020] Before the leaching operation, the drainage chamber 17 is installed first, the crushed material is put into the tank body by opening the upper cover 2, and the leaching solvent is put into the tank body 1 through the feed port 8. The air flow valve 6 is used to adjust the tank body air pressure during the leaching process. After the feeding is completed, the leaching is carried out. When the leaching is completed, the discharge port is connected to the receiving bucket by a pipeline, and after the air flow valve 6 is opened, the liquid outlet valve 7 is controlled to release the liquid. In the later stage of discharging, the air pump can be connected to the air flow valve 6 for pressurization to further increase the discharging speed.

[0021] In this embodiment, the present device and the same extraction tank without drainage equipment were used for leaching. Both were put into 60kg of jasmine tea and 200kg of water. After leaching at room temperature for 1 hour, the liquid was naturally discharged. Among them, the feeding time of the present embodiment device was about 20 minutes, and the liquid was released in 1.5 hours, and 125kg of jasmine tea clear liquid was obtained; the feeding time of the comparative device was more than 30 minutes, and the liquid was released after 4 hours, and 116kg of jasmine tea clear liquid was obtained. After testing, the two had the same composition.

[0022] Embodiment 2

[0023] The same as in Example 1, except that in this embodiment, the present device is used for leaching, 60 kg of the same jasmine tea in powder form and 200 kg of water as in Example 1 are added, and after leaching at room temperature for 1 hour, the liquid is naturally discharged for 30 minutes, and then the upper air flow valve 6 is connected to the air pump to pressurize to about 0.2 MPa to assist in discharging. The liquid is discharged 0.5 hours after the start of pressurization, and the total discharge time is 1 hour, and 139 kg of jasmine tea clear liquid is obtained. After testing, its composition is the same as the clear liquid in the previous embodiment.
