A high-efficiency fractionation device for peppermint essential oil

Abstract

This utility model relates to the field of essential oil fractionation technology, specifically disclosing a high-efficiency peppermint essential oil fractionation device, including a fractionation tank. A vibration scraping mechanism is provided at the top of the fractionation tank, and a heat recovery mechanism is provided on one side of the vibration scraping mechanism. The vibration scraping mechanism includes a placement bucket and a sliding scraper that slides around the inner wall of the placement bucket. The placement bucket is located at the top of the fractionation tank, and a cleaning component is provided between the placement bucket and the sliding scraper for scraping off peppermint residue remaining on the inner wall after fractionation. As the sliding scraper slides along the inner wall of the placement bucket, the rounded corner at the bottom of the sliding scraper contacts the tops of distributed limiting posts, causing the rounded corner on one side of the bottom of the sliding scraper to pass along the tops of the distributed limiting posts. This causes the sliding scraper to vibrate upon resetting, dislodging the peppermint adhering to the surface of the sliding scraper, effectively reducing the amount of peppermint residue remaining on the scraper surface, thus improving the cleaning speed.

Description

Technical Field

[0001] This utility model relates to the field of essential oil fractionation technology, specifically to a high-efficiency fractionation device for peppermint essential oil. Background Technology

[0002] Peppermint extracts, obtained through water distillation or subcritical low-temperature extraction, have a refreshing and cool flavor that invigorates the mind and body. They are highly effective in soothing the throat, eliminating bad breath, and have a unique therapeutic effect on calming the mind and body. Peppermint is one of the ten essential oils that beginners and those new to essential oils should always have.

[0003] Chinese patent CN217077520U discloses a high-efficiency fractionation device for peppermint essential oil. When peppermint is firmly confined in a container consisting of a storage cylinder and a positioning cylinder, water can freely enter and exit the storage mechanism through a vent hole. The peppermint is firmly confined inside the storage mechanism. When the staff removes the storage mechanism, there will be no large amount of peppermint residue left inside the fractionation tank. This not only reduces the difficulty of cleaning the fractionation tank for the staff, but also shortens the downtime of the fractionation tank, thereby accelerating the fractionation efficiency of peppermint essential oil.

[0004] When the above-mentioned high-efficiency fractionation device for peppermint essential oil is used, fresh leaves are directly fractionated. The moisture content of fresh peppermint leaves is >85%. Under the action of high-temperature steam, the cell walls break down and release pectin-like substances, causing the raw material to gelatinize and stick to the wall. The residue is not completely removed and may be mixed into the new peppermint oil in the next fractionation process, resulting in a decline in product quality and possibly affecting its purity and characteristics. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency fractionation device for peppermint essential oil to solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a fractionating tank, characterized in that: a vibration scraping mechanism is provided at the top of the fractionating tank, and a heat recovery mechanism is provided on one side of the vibration scraping mechanism; the vibration scraping mechanism includes a placement bucket and a sliding scraper that slides around the inner wall of the placement bucket; the placement bucket is located at the top of the fractionating tank; a cleaning component is provided between the placement bucket and the sliding scraper for scraping off the mint residue remaining on the inner wall after fractionation; the heat recovery mechanism includes a nozzle and a corrugated pipe fixedly connected to one end of the nozzle; the nozzle is slidably connected to the inner wall of the placement bucket; and a rinsing component is provided at one end of the corrugated pipe for collecting the heat emitted during fractionation.

[0007] Preferably, the cleaning component includes a sleeve that is slidably connected to the inner wall of the placement bucket. A folding spring is fixedly installed inside the sleeve. One end of the sliding scraper is slidably connected inside the sleeve. One end of the folding spring is fixedly installed to the top of the sliding scraper. Limiting grooves are provided on both sides of the sliding scraper. The inner wall of the sleeve slides within the limiting grooves.

[0008] Preferably, the inner wall of the placement bucket is surrounded by limit posts, a gear ring is fixedly connected to one side of the sleeve, a drive gear is meshed on one side of the gear ring, a motor is fixedly connected to the upper surface of the drive gear, and the motor is fixedly installed on the outer wall of the placement bucket.

[0009] Preferably, the flushing assembly includes a guide pipe, one end of which is fixedly connected to the bottom end of a corrugated pipe, and the other end of which is fixedly connected to a water storage tank, with a connecting pipe fixedly connected inside the water storage tank.

[0010] Preferably, the lower surface of the water storage tank is fixedly connected to the top of the fractionation tank, fins are installed around the connecting pipe, and an inclined plate is fixedly connected to the top of the connecting pipe.

[0011] Preferably, a filter plate is fixedly connected to one end of the inclined plate, a one-way valve is fixedly installed on the inclined plate, and a cylinder is fixedly connected to one end of the nozzle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. As the sliding scraper slides along the inner wall of the container, the rounded corner at the bottom of the scraper contacts the top of the distributed limit posts. This causes the rounded corner on one side of the bottom of the scraper to pass along the top of the distributed limit posts, resulting in vibration when the scraper returns to its original position. This shakes off the mint adhering to the surface of the scraper, effectively reducing the amount of mint residue left on the scraper surface and avoiding wasting time on manual cleaning. This not only improves the cleaning speed but also ensures a more thorough cleaning effect.

[0014] 2. The heat from the steam is transferred to the water in the storage tank through the fins distributed on the connecting pipe, thus heating the water in the storage tank. The nozzle inside the placement tank is pushed out by the output end of the cylinder to clean the inner wall of the placement tank again. By recovering the waste heat from the steam to heat the water, the demand for new heat sources can be reduced, thereby reducing energy consumption and improving the overall energy utilization rate.

The inner wall of the sleeve 203 slides within the limiting grooves 205 on the sliding scraper 202 to prevent the sliding scraper 202 from falling out of the sleeve 203.

[0027] Furthermore, a limit post 206 is installed around the inner wall of the placement bucket 201. A gear ring 207 is fixedly connected to one side of the sleeve 203. A drive gear 208 is meshed on one side of the gear ring 207. A motor 209 is fixedly connected to the upper surface of the drive gear 208. The motor 209 is fixedly installed on the outer wall of the placement bucket 201. The top cover of the placement bucket 201 is connected to the upper surface of the gear ring 207. A lifting bracket is connected between the top cover and the body of the placement bucket 201. The motor 209 is fixedly connected to the outer wall of the top cover. A control valve is installed in the exhaust pipe on the upper surface of the top.

[0028] Furthermore, the flushing assembly includes a guide pipe 303, one end of which is fixedly connected to the bottom end of the corrugated pipe 302, and the other end of which is fixedly connected to a water storage tank 304. A connecting pipe 305 is fixedly connected inside the water storage tank 304. The connecting pipe 305 is located at the center of the water storage tank 304 and is connected to the fractionation tank 100 below. A cover plate is provided on the upper surface of the water storage tank 304.

[0029] Furthermore, the lower surface of the water storage tank 304 is fixedly connected to the top of the fractionation tank 100, fins 306 are installed around the connecting pipe 305, and an inclined plate 307 is fixedly connected to the top of the connecting pipe 305. A slope is provided at the inclined plate 307, and a switchable partition is provided at one end of the filter plate 308 of the inclined plate 307.

[0030] Furthermore, a filter plate 308 is fixedly connected to one end of the inclined plate 307, a one-way valve 309 is fixedly installed on the inclined plate 307, a cylinder 310 is fixedly connected to one end of the nozzle 301, the cylinder 310 is installed on the support plate, and the bottom end of the support plate is fixedly connected to the upper surface of the fractionation tank 100.

[0031] Working principle: Initially, the nozzles 301 in the placement tank 201 are all in the retracted state, the sliding scraper 202 is in contact with the inner wall of the placement tank 201, the bottom end of the sliding scraper 202 is in the middle position of the two limiting posts 206, and the folding spring 204 between the sleeve 203 and the sliding scraper 202 has not yet been compressed. By putting the mint into the placement tank 201, the steam in the fractionation tank 100 enters the placement tank 201 through the connecting pipe 305 to fractionate the mint. Through the fins 306 distributed on the connecting pipe 305, the heat in the steam is transferred to the water in the water storage tank 304 to heat the water in the water storage tank 304.

[0032] The output of the motor 209 drives the drive gear 208 to rotate. The drive gear 208 drives the gear ring 207 meshing on one side to rotate on the placement bucket 201. The sleeve 203 fixed to the inner wall of the gear ring 207 will also rotate along the inner wall of the placement bucket 201, driving the sliding scraper 202 sleeved inside the sleeve 203 to slide and scrape along the inner wall of the placement bucket 201.

[0033] As the sliding scraper 202 slides along the inner wall of the placement bucket 201, the rounded corner at the bottom of the sliding scraper 202 contacts the top of the distributed limiting posts 206, causing the rounded corner on one side of the bottom of the sliding scraper 202 to pass along the top of the distributed limiting posts 206. During this process, the sliding scraper 202 slides inside the sleeve 203 and squeezes the folded spring sheet 204 between the sleeve 203 and the sliding scraper 202, causing the sliding scraper 202 to rise along the inner wall of the placement bucket 201. When the sliding scraper 202 passes the limiting post 206, the compressed folded spring sheet 204 will push the sliding scraper 202 to slide downward, causing the sliding scraper 202 to vibrate when it resets, shaking off the mint adhering to the surface of the sliding scraper 202.

[0034] After the sliding scraper 202 has finished scraping the mint off the inner wall of the placement bucket 201, the output of the motor 209 stops working. The output of the cylinder 310 pushes the nozzle 301 in the placement bucket 201 to extend. The hot water in the water storage tank 304 is transported to the nozzle 301 through the guide pipe 303. The nozzle 301 sprays the hot water evenly into the placement bucket 201, cleaning the inner wall of the placement bucket 201 again. The water carries the mint from the bottom of the placement bucket 201 into the inclined plate 307. The inclined plate 307 collects the mint and water onto the filter plate 308 at one end. The filter plate 308 intercepts the mint in the water, allowing the water to flow through the filter plate 308 into the water storage tank 304 below, where the water source can be recycled.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
