Description

Technical Field

[0001] This application relates to the technical field of vacuum precooling of vegetables, and in particular to a vacuum precooling and freshness-locking device for vegetables. Background Technology

[0002] The vegetable vacuum precooling device is a specialized piece of equipment that utilizes the physical principle of low-temperature evaporation and heat absorption of water in a vacuum environment to rapidly cool fresh vegetables, inhibit physiological activities and microbial growth, thereby achieving the purpose of preservation. It creates a sealed vacuum space, reduces the ambient air pressure to lower the boiling point of water, and promotes the evaporation of water in the vegetables at low temperatures, absorbing heat and rapidly reducing the temperature of the vegetables to the target preservation temperature (usually 0-10℃). It is a key piece of equipment for achieving rapid precooling and extending shelf life in the post-harvest processing of vegetables.

[0003] Regarding the aforementioned technologies, the inventors have discovered the following defects: In the prior art, the moisture evaporated from the surface of vegetables during the pre-cooling process is prone to condense on the inner wall of the device. If it is not cleaned in time, it will lead to uneven humidity distribution in the chamber during subsequent pre-cooling, affecting the cooling efficiency and freshness-locking effect of the vegetables. At the same time, vegetable debris and impurities are easily attached to the inner wall of the device, which will also affect the preservation quality of the vegetables if not cleaned in time. Utility Model Content

[0005] This application provides a vegetable vacuum precooling and freshness-locking device, which adopts the following technical solution: it includes a box body, the front of the box body is rotatably connected to a box door via a rotating rod, the top of the box body is provided with a fixing groove, a hydraulic push rod is fixedly connected to the inner wall of the fixing groove, and a push rod is fixedly connected to the bottom output end of the hydraulic push rod; A connecting plate is fixedly connected to the bottom of the push rod, a connecting frame is fixedly connected to the bottom of the connecting plate, a scraper is fixedly connected to the right side of the connecting frame, a scraper is provided below the scraper, a cleaning roller is rotatably connected to the inner wall of the connecting frame, and a gear is fixedly connected to the back of the cleaning roller.

[0006] Optionally, the right side of the connecting frame away from scraper one is fixedly connected to the left side of scraper two, and the outer wall of the cleaning roller is in contact with the right side of the inner wall of the box.

[0007] Optionally, the right sides of both scraper one and scraper two are in contact with the right side of the inner wall of the box, and a fixing plate is fixedly connected to the inner wall of the box.

[0008] Optionally, a sliding groove is provided on the back of the fixing plate, and a rack is fixedly connected to the back of the fixing plate, with the left side of the rack meshing with the right side of the gear.

[0009] Optionally, a flow channel is fixedly connected to the right side of the inner wall of the box, a flow guide plate is fixedly connected to the inner wall of the flow channel, an arc-shaped flow channel is fixedly connected to the back of the flow channel, and an arc-shaped flow guide plate is fixedly connected to the inner wall of the arc-shaped flow channel.

[0010] Optionally, a connecting box is fixedly connected to the left side of the arc-shaped drainage channel, a connecting pipe is fixedly connected to the back of the connecting box, and a collection box is fixedly connected to the back of the connecting pipe. The number of drainage channels is two.

[0011] Optionally, the two drainage channels are symmetrically arranged with the push rod as the center. There are two arc-shaped drainage channels, and the right side of the arc-shaped drainage channel on the left side is fixedly connected to the left side of the connecting box.

[0012] In summary, this application includes the following beneficial technical effects: 1. When the connecting frame is driven to move downward by a hydraulic push rod with components such as scraper one, scraper two, and cleaning roller, scraper one and scraper two can scrape off impurities and condensed water attached to the inner wall. At the same time, the cleaning roller rotates under the meshing action of gear and rack, further cleaning the inner wall by rolling. This effectively avoids the residue of impurities and the growth of bacteria, and extends the service life of the device.

[0013] 2. This utility model incorporates components such as a drainage channel, an arc-shaped drainage channel, and a collection box. After the cleaning component scrapes the dirt or condensation on the inner wall downwards, it falls into the drainage channel. Since the drainage channel is angled downwards, it flows under the action of the guide plate, then enters the arc-shaped drainage channel through the arc-shaped guide plate, and finally flows into the collection box through the connecting box and connecting pipe. This avoids water residue in the box, facilitates collection, and also ensures the stability of the pre-cooling environment, improving the uniformity of vegetable cooling and the freshness-locking effect.

[0019] Please see Figure 4As shown, a flow channel 3 is fixedly connected to the right side of the inner wall of the box 1. The flow channel 3 is set at an angle downward so that the liquid can flow along this angle. A guide plate 31 is fixedly connected to the inner wall of the flow channel 3. The guide plate 31 can make the scraped liquid or dirt flow under its action. An arc-shaped flow channel 32 is fixedly connected to the back of the flow channel 3. The arc-shaped flow channel 32 is also set at an angle to facilitate the liquid to flow down. An arc-shaped guide plate 321 is fixedly connected to the inner wall of the arc-shaped flow channel 32.

[0020] Please see Figure 2 As shown, the right side of the connecting frame 21, away from scraper 1 211, is fixedly connected to the left side of scraper 212, and the outer wall of the cleaning roller 22 is in contact with the right side of the inner wall of the box 1.

[0021] Please see Figure 4 As shown, a connecting box 33 is fixedly connected to the left side of the arc-shaped drainage channel 32, a connecting pipe 34 is fixedly connected to the back of the connecting box 33, and a collection box 341 is fixedly connected to the back of the connecting pipe 34. The collection box 341 can collect liquid and dirt, and the collection box 341 can be disassembled from the connecting pipe 34. There are two drainage channels 3.

[0022] Please see Figure 2 As shown, scraper 1 211 and scraper 2 212 are both in contact with the right side of the inner wall of the box 1, and a fixing plate 23 is fixedly connected to the inner wall of the box 1.

[0023] Please see Figure 4 As shown, the two drainage channels 3 are symmetrically arranged with the push rod 121 as the center. There are two arc-shaped drainage channels 32. The two arc-shaped drainage channels 32 are symmetrically arranged. The right side of the arc-shaped drainage channel 32 on the left side is fixedly connected to the left side of the connecting box 33.

[0024] Please see Figure 3 As shown, a sliding groove 231 is provided on the back of the fixing plate 23.

When condensation or dirt appears on the inner wall of the box 1, the hydraulic push rod 12 in the fixed groove at the top of the box 1 can be activated, causing the push rod 121 at its output end to move downward, thereby driving the connecting plate 2 and the connecting frame 21 to move downward synchronously. During the downward movement of the connecting frame 21, the scraper 1 211 and scraper 212 on the left and right sides contact the left and right sides of the inner wall of the box 1, scraping away impurities, dirt and condensation on the inner wall. At the same time, the cleaning roller 22 on the inner wall of the connecting frame 21 moves downward with the connecting frame 21, and the gear 241 on its back moves downward. Engaging with the rack 24 on the back of the fixed plate 23, the cleaning roller 22 rotates during movement, rolling and cleaning the inner wall of the box 1 to ensure cleanliness and improve cleaning effect. The water generated during the pre-cooling process enters the diversion groove 3 under the action of gravity and scraper 1 211 and scraper 212. Since the diversion groove 3 is set at an angle downward, and under the action of the guide plate 31, it is guided to the connecting box 33 through the arc guide plate 321 in the arc diversion groove 32, and then collected into the collection box 341 through the connecting pipe 34, realizing the centralized treatment and collection of water. The entire device is set at an angle. After the pre-cooling and cleaning work is completed, the hydraulic push rod 12 drives the push rod 121, the connecting plate 2 and the connecting frame 21 to reset, waiting for the next operation.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
