Description

Technical Field

[0001] The utility model relates to the technical field of spice extraction equipment, in particular to an extraction device with easy material separation. Background Art

[0002] Natural spices have become a hot spot in the research and development of spices because they are derived from nature, have a harmonious proportion of ingredients, have realistic aromas, and are green and healthy. At present, among the methods for preparing natural spices from natural plants, the most widely used industrial method is still the solvent extraction method. Its main principle is to select a suitable solvent for extraction based on the solubility of various target components in natural plants in different solvents. Commonly used solvent extraction methods include immersion, percolation, decoction, reflux extraction, and continuous extraction. According to the extraction temperature (or whether it is heated), they can be divided into hot extraction and cold extraction.

[0003] In the prior art, the solvent extraction method for preparing natural spices generally uses a solvent to soak natural plants for a certain period of time (heating or not, reflux or not), and then the extraction is completed; then the extract is filtered and collected, and the material residue is discarded or used for other purposes. In the prior art, either a filter is set at the discharge port of the extraction device. Since the diameter of the discharge port is relatively small, a large amount of material accumulation on the filter will cause the discharge speed to become slower and slower; or all the materials and solutions are released first and then filtered. At this time, on the one hand, a turnover container with the same volume as the extraction device is required, and on the other hand, an additional process will be added when filtering, making the entire filtering process complicated.

[0004] Natural plant materials have strong solvent absorption characteristics, especially after long-term solvent immersion, they will absorb more solvent. Therefore, no matter which of the above filtration methods is used, since the filtration is carried out under normal pressure, a large amount of extract will be absorbed in the material, resulting in incomplete collection of the extract, low extraction efficiency, low material utilization, and great waste.

[0025] In this embodiment, the extraction mechanism 2 includes a retractable filter 21, a retractable assembly 22, a rotating assembly 23 and a sleeve 24. The retractable assembly 22 is connected to the retractable filter 21 for controlling the switching between the retracted state and the expanded state of the retractable filter 21. The rotating assembly 23 is connected to the retractable filter 21 for controlling the rotation of the retractable filter 21 in the container 1. The sleeve 24 extends into the container 1 and wraps the structure of the retractable assembly 22 and the rotating assembly 23 located in the container 1 therein.

[0026] In this embodiment, the retractable filter screen 21 is composed of a plurality of fan-shaped petal-like blades 211 and a central disk 212. The fan-shaped petal-like blades 211 are preferably made of hard stainless steel. The plurality of fan-shaped petal-like blades 211 are arranged along the outer circumference of the central disk 212 to form a petal-like structure. The central disk 212 and the fan-shaped petal-like blades 211 are both provided with a plurality of filter holes 213. The central disk 212 is also provided with a plurality of outlets 214 that can be opened downward. The connection between the outlet 214 that can be opened downward and the central disk 212 is similar to a loose-leaf, and one end of the outlet 214 is connected to the central disk 212 in the form of a loose-leaf; the buckle at the bottom of the central disk 212 clamps the outlet 214 during extraction; after the extraction is completed, the buckle is opened, and the outlet 214 automatically opens downward to discharge the material.

[0027] In this embodiment, the retractable assembly 22 includes a rope 221 and a rope retractable unit 222. One end of the rope 221 passes through the retractable openings on the outer periphery of several fan-shaped petal-shaped blades 211 in sequence, and the other end of the rope 221 passes through the container 1 and is connected to the rope retractable unit 222 located outside the container 1.

[0028] In this embodiment, the rotating assembly 23 includes a motor 231 located outside the container 1 and a rotating shaft 232 extending into the container 1 and connected to the middle of the retractable filter 21 .

[0029] In this embodiment, before the extraction begins, the fan-shaped petal blades 211 of the retractable filter 21 are in an open state, and the downwardly openable outlets 214 on the central disk 212 are all closed, and the retractable filter 21 plays the role of carrying natural materials; after the extraction is completed, the ropes 221 connected to the outer periphery of the fan-shaped petal blades 211 of the retractable filter 21 gradually shrink the ropes 221 through the rope retraction unit 222, so that the fan-shaped petal blades 211 shrink and gather toward the center, and first squeeze out the extract absorbed by the natural plant material; then start the motor 231, and the retractable filter 21 after shrinking further spins out the extract in the natural plant material under the action of centrifugal force, so that the extract absorbed in the natural plant material can be fully collected by first squeezing and then spinning, thereby improving the utilization rate and extraction efficiency of natural raw materials. After the extrusion and drying are completed and the extract is completely collected, the discharge pipe 3 (including the filter 4 and the valve 5 arranged in sequence in the discharge pipe 3) is disassembled as a whole, and the buckle of the fixed outlet 214 on the central disk 212 is opened from the discharge port at the bottom of the container 1. The outlet 214 opens downward, and the extracted residue falls downward at this time, and is discharged through the discharge port.

[0030] The specific operation process of the material easy-to-separate extraction device of the utility model is as follows:

[0031] Add the natural plant raw material into the retractable filter screen 21 (the fan-shaped petal-shaped blades 211 are in an open state at this time) in the container 1 through the feeding port 11, add the extraction solvent, and close the feeding port 11. Extract the natural plant according to the set extraction temperature and extraction time. After the extraction is completed, open the valve 5 and collect the extract flowing out of the discharge pipe 3. When the feed liquid no longer flows out in a linear shape, turn on the switch of the rope retracting unit 222, gradually retract the rope 221, and gradually retract the fan-shaped petal-shaped blades 211 of the retractable filter screen 21. When the extruded extract no longer flows out in a linear shape, turn off the switch of the rope retracting unit 222 and let it stand for 3-5 minutes. Then turn on the control switch of the motor 231, and the retractable filter screen 21 in the retracted state rotates at a high speed. When there is no obvious extract thrown out, it can be stopped. During this period, continue to collect the extract flowing out of the discharge pipe 3.
