Description

Technical Field

[0001] This application relates to the technical field of freeze-drying processing of double-petaled roses, and in particular to a freeze-drying production system and process for freeze-dried double-petaled roses. Background Technology

[0002] Currently, double-petaled roses refer to a type of rose with more petals inside the flower, making the flower appear fuller and thicker. These roses typically have a rich fragrance and a full bloom, giving a luxurious and elegant feel. Different varieties of double-petaled roses have their own unique colors, shapes, and fragrances. Roses are rich in anthocyanins; however, free anthocyanins are extremely rare under natural conditions, mainly existing in the form of glycosides. Anthocyanins often form anthocyanin glycosides with one or more glucose, rhamnose, galactose, arabinose, etc., through glycosidic bonds. These glycosides have the properties of being used both as food and medicine. These plants or foods not only provide nutrition and satisfy people's appetites but also possess certain medicinal effects. Anthocyanins, due to their unique functionalities, are used to scavenge free radicals in the human body, promote lutein production, and have anti-tumor, anti-cancer, anti-inflammatory, lipid peroxidation and platelet aggregation inhibition, prevent diabetes, aid weight loss, and protect eyesight. Moreover, as a natural pigment, anthocyanins are safe, non-toxic, and have many health benefits for the human body, and have been applied in the food, health products, cosmetics, and pharmaceutical industries.

[0003] Freeze-drying technology for roses can effectively preserve the shape of the rose petals and lock in the nutrients within the rose petals to the maximum extent, preventing nutrient loss. However, existing freeze-drying technologies for roses are relatively slow, requiring more than twelve hours to complete the process. Due to the long time from raw material to the end of freeze-drying, the rose petals lose nutrients and discolor, seriously affecting the yield and quality of freeze-dried roses. Summary of the Invention

[0004] In order to reduce the loss of nutrients in roses and improve the quality of freeze-dried roses, this application provides a freeze-drying production system and process for freeze-dried double-petal roses.

[0005] Firstly, this application provides a freeze-drying production system for freeze-dried double-petaled roses, which adopts the following technical solution:

[0006] A freeze-drying production system for freeze-dried double-petaled roses includes a frame, a feeding mechanism, a freeze dryer, and a packaging chamber. The feeding mechanism, freeze dryer, and packaging chamber are all mounted on the frame. A tunnel-type quick-freezing machine is mounted on the frame and located at the feed end of the freeze dryer. The feeding mechanism conveys the double-petaled roses to the tunnel-type quick-freezing machine for quick freezing, then they enter the freeze dryer for vacuum drying, and finally the freeze-dried double-petaled roses are conveyed to the packaging chamber for packaging.

[0007] By adopting the above technical solution, when freeze-drying double-petal roses, the roses are placed on the feeding mechanism by manual feeding. The feeding mechanism transports the double-petal roses to the tunnel-type quick-freezing machine for rapid freezing, shortening the freezing time and reducing the loss of nutrients and discoloration of the petals. Then, they are transported to the freeze dryer for vacuum drying to remove ice crystals. After freeze-drying, the double-petal roses are destemmed and then packaged in the packaging room. Through the above settings, the quality of freeze-dried roses is improved, and the freeze-drying efficiency is also increased.

[0008] Optionally, the feeding mechanism includes a feeding platform, a feeding tray, and a conveying assembly. The feeding platform and the conveying assembly are both mounted on the frame. The feeding platform is located on both sides of the conveying assembly. The feeding tray is placed on the feeding platform for manual feeding. The feeding tray has multiple flower insertion holes.

[0009] By adopting the above technical solution, when feeding double-petaled roses, workers insert the cleaned roses one by one into the flower holes, and then transport the feeding tray from the feeding platform to the conveying component. The conveying component transports the roses to the tunnel-type quick-freezing machine for quick freezing, followed by freeze-drying and stem removal, and then packaging. The feeding mechanism has a simple structure, and the manual feeding method reduces the obstruction between double-petaled roses, allowing each rose to be separated, which facilitates the freeze-drying process and improves the quality of freeze-dried roses.

[0010] Optionally, the packaging chamber is provided with a stem-removing mechanism, which includes a fixing frame, stem-removing straight blades, and a drive assembly. The fixing frame is mounted on the machine frame, and multiple stem-removing straight blades are slidably mounted on the fixing frame. The multiple stem-removing straight blades are grouped in pairs, with the two stem-removing straight blades in each group corresponding to a row of flower insertion holes and located on both sides of them. The drive assembly is mounted on the fixing frame and drives the two stem-removing straight blades in each group to move closer to each other.

[0011] By adopting the above technical solution, after the double-petal roses are freeze-dried, the feeding tray is conveyed to the stem removal mechanism by the conveying component. The drive component drives the stem removal blades to move in opposite directions, and the stem removal blades separate the roses from the stems. The staff picks out the roses for packaging. The stem removal mechanism makes the removal of the stems convenient and simple, reduces manual cutting, improves work efficiency, and improves the quality of freeze-dried roses.

[0012] Optionally, the driving assembly includes a driving cylinder, insert blocks, a return spring, and a guide rod. The guide rod is mounted on the fixed frame, and multiple stem-removing straight blades slide on the guide rod. The driving cylinder is mounted on the fixed frame, and multiple insert blocks slide on the fixed frame. The insert blocks move closer to or away from the stem-removing straight blades via the driving cylinder. The insert blocks can be inserted between two adjacent groups of stem-removing straight blades, and drive the two stem-removing straight blades in each group to move closer to each other. A return spring is provided between the two stem-removing straight blades in each group, and the return spring drives the two stem-removing straight blades in the same group to move away from each other.

[0013] By adopting the above technical solution, when the feeding tray moves to the stem removal mechanism, the drive cylinder is activated. The drive cylinder drives the insert block to slide, and the insert block moves towards the stem removal blade, causing the two stem removal blades in each group to move closer to each other, so that the stem removal blades can cut the stems of the roses. The drive component has a simple structure, is easy to operate, and quickly resets after cutting, which facilitates the cutting of roses on the next tray, improves work efficiency, improves cutting quality, and improves the quality of freeze-dried roses.

[0014] Optionally, the stem-removing mechanism is provided in multiple sets and operates alternately; the stem-removing straight blade is provided with multiple blocking strips, and the blocking strips on adjacent stem-removing straight blades are staggered.

[0015] By adopting the above technical solution, after one set of stem-removing mechanisms has finished removing the stems, the barrier strips block the roses, reducing the number of roses falling. Then another set of stem-removing mechanisms works, while the previous set of stem-removing mechanisms transports the roses to one side, where workers can remove them for packaging. Through the above setup, the number of roses falling can be reduced, damage to the roses can be minimized, and the alternating operation facilitates the collection of roses.

[0016] Optionally, the frame is provided with a sorting mechanism, which is located on one side of the stem removal mechanism. The sorting mechanism includes a connecting frame, stem removal pins, and a first lifting assembly. The connecting frame slides vertically on the frame via the first lifting assembly. The connecting frame is provided with a plurality of stem removal pins, each corresponding to a flower insertion hole.

[0017] By adopting the above technical solution, after the flower stems are cut, some flower stems fall into the flower holes and cannot be removed. The first lifting component drives the connecting frame to rise, and the connecting frame drives the stem removal pin to insert into the flower hole and push out the flower stem, thus completing the removal of flower stems from the feeding tray. Then, the feeding tray can be transported to the feeding platform for rose insertion. The set sorting mechanism reduces the degree of manual intervention, while quickly completing the removal of flower stems, improving work efficiency and reducing the manual tray cleaning cost.

[0018] Optionally, the sorting mechanism further includes an adsorption component and a second lifting component. The adsorption component slides vertically onto the frame via the second lifting component. The adsorption component is used to adsorb the feeding tray, and the second lifting component drives the feeding tray toward the stem-removing needle.

[0019] By adopting the above technical solution, when removing flower stems, the second lifting component drives the adsorption component to descend, and the adsorption component drives the feeding tray to descend. The stem removal pin moves closer to the feeding tray, inserts into the flower insertion hole, and pushes out the flower stem. The adsorption component and the second lifting component improve the efficiency of flower stem removal, while fixing the feeding tray and reducing its movement during the flower stem removal process. This maintains the efficiency of flower stem removal, facilitates the subsequent insertion and feeding of roses, and improves the efficiency of freeze-dried roses.

[0020] Optionally, the sorting mechanism further includes a fan, a nozzle, and a collection hopper. The fan is mounted on the frame and located on one side of the feeding tray. The nozzle is located at the air outlet of the fan and faces the feeding tray. The collection hopper is mounted on the frame and located on the opposite side of the fan, and is used to collect the blown-down rose stems.

[0021] By adopting the above technical solution, after the flower stem is pushed out, the blower is started. The blower blows the flower stem on the feeding tray through the air nozzle, so that the flower stem enters the collection hopper. Through the above settings, the collection of flower stems becomes simple, the chance of flower stems scattering everywhere is reduced, and environmental hygiene is improved.

[0022] Optionally, the sorting mechanism further includes a side-shifting conveyor belt, which is disposed on the frame and located on both sides of the connecting frame. The side-shifting conveyor belt is used to transport the falling loading pallet to one side.

[0023] By adopting the above technical solution, after the flower stems fall, the side-shifting conveyor belt moves the feeding tray to one side, where workers collect and sort them for the next step of inserting roses. The side-shifting conveyor belt reduces the accumulation of the feeding tray at the stem removal mechanism, thus reducing the impact on the stem removal work.

[0024] Secondly, this application provides a freeze-drying production process for freeze-dried double-petaled roses, which adopts the following technical solution:

[0025] A freeze-drying production process for freeze-dried double-petaled roses includes the following steps:

[0026] S1. Preparation: Clean the roses and arrange them on a plate manually;

[0027] S2. Quick freeze drying: Place the tray into a tunnel-type quick freezer for quick freezing and preservation.

[0028] S3. Vacuum drying: The quick-frozen roses are sent into a freeze dryer for vacuum drying to remove ice crystals.

[0029] S4. Stem removal and packaging: Remove the stems from the freeze-dried double roses and then package them.

[0030] By adopting the above technical solution, in the freeze-drying of double-petaled roses, the roses are first cleaned to remove dirt, then placed on a tray and conveyed into a tunnel-type quick-freezing machine for quick freezing. The quick-frozen roses are then conveyed into a freeze dryer for vacuum drying to remove ice crystals. They are then conveyed to one side for stem removal, and finally, the stem-removed double-petaled roses are packaged. Through these steps, rapid freeze-drying of double-petaled roses is achieved, effectively reducing nutrient loss, preserving flower color, and improving the quality of freeze-dried roses.

[0031] In summary, this application includes the following beneficial technical effects:

[0032] 1. During the freeze-drying of double-petaled roses, the roses are placed on a feeding mechanism by manual feeding. The feeding mechanism then transports the double-petaled roses to a tunnel-type quick-freezing machine for rapid freezing, shortening the freezing time and reducing the loss of nutrients and discoloration of the petals. The roses are then transported to a freeze dryer for vacuum drying to remove ice crystals. After freeze-drying, the double-petaled roses are destemmed and packaged in a packaging room. This process improves both the quality and efficiency of the freeze-dried roses.

[0033] 2. During the stem removal process, the second lifting component lowers the adsorption component, which in turn lowers the feeding tray. The stem removal pin moves closer to the feeding tray, inserts into the flower insertion hole, and pushes out the flower stem. The adsorption component and the second lifting component improve the stem removal efficiency and fix the feeding tray, reducing its movement during stem removal. This maintains the stem removal efficiency, facilitates subsequent rose insertion, and improves the efficiency of freeze-dried roses.

[0034] 3. When freeze-drying double-petal roses, the roses are first cleaned to remove dirt, then placed on a tray and conveyed into a tunnel-type quick-freezing machine for quick freezing. The quick-frozen roses are then conveyed into a freeze dryer for vacuum drying to remove ice crystals. Afterward, the stems are removed, and the stem-removed double-petal roses are packaged. These steps achieve rapid freeze-drying of double-petal roses, effectively reducing nutrient loss, preserving flower color, and improving the quality of the freeze-dried roses.

The feeding conveyor belt 752 is located on the side of the discharge side conveyor roller group 232 of the freeze dryer 300 away from the freeze dryer 300, and it moves vertically via the second cylinders 751. An adsorption assembly 740, which is an electromagnet, is provided on the side of the feeding conveyor belts 752 that are close to each other. Four electromagnets are provided. The frame 100 is equipped with a first... A lifting assembly 730 includes a first cylinder, which can be multiple. A connecting frame 710 is fixedly connected to the piston rod of the first cylinder. The connecting frame 710 is located between two feeding conveyor belts 752. Multiple rows of stem-removing pins 720 are fixedly connected to the connecting frame 710. The stem-removing pins 720 correspond to the flower holes 223. The end of the stem-removing pin 720 away from the connecting frame 710 is pointed. After the flower stem is removed, the second cylinder 751 drives the feeding tray 220 on the feeding conveyor belt 752 to descend. The stem-removing straight knife 620 drives the petals to separate from the feeding tray 220. When the feeding tray 220 descends, the first cylinder drives the stem-removing pins 720 on the connecting frame 710 to insert into the flower holes 223, so that the flower stem is separated from the feeding tray 220.

[0053] To facilitate the collection of the feeding tray 220 separated from the flower stem, two side-shifting conveyor belts 770 are fixedly connected to the frame 100.

Then, the feeding tray 220 is placed on the conveyor belt 231, which transports the feeding tray 220 to the conveyor roller group 232. The conveyor roller group 232 transports the feeding tray 220 to the tunnel-type quick-freezing machine 500 for quick-freezing. After quick-freezing, the feeding tray 220 slides out of the tunnel-type quick-freezing machine 500 and is transported to the freeze dryer 300 by the conveyor roller group 232. The feeding tray 220 is placed into the freeze dryer 300 by manual or automatic means. Then, after vacuum drying in the freeze dryer 300, the feeding tray 220 in the freeze dryer 300 is transported to the packaging room 400.

Then, the drive cylinder 631 is activated, which drives the insert block 632 on the connecting rod 635 to move closer to the fixed frame 610. The insert block 632 drives the two stem-removing straight knives 620 to move closer to each other, separating the flower stem from the flower. Then, the second cylinder 751 drives the feeding tray 220 to move down, and the rotating plate 900 drives the stem-removing straight knife 620 to rotate above the collection hopper 650 on one side. The workers can then remove the flowers for packaging or sweep them into the collection hopper 650 for freeze-dried rose packaging.

[0057] During the descent of the feeding tray 220, the electromagnet is activated, attracting the feeding tray 220 and activating the first cylinder. The first cylinder drives the connecting frame 710 to rise, and the connecting frame 710 drives the stem removal pin 720 to insert into the flower insertion hole 223 and push out the flower stem. Then, the blower 761 is activated, and the blower 761 blows the flower stem into the receiving hopper 763 through the nozzle 762. Then, the electromagnet is turned off, and the first cylinder drives the stem removal pin 720 to separate from the feeding tray 220. Then, the side conveyor belt 770 is activated, and the side conveyor belt 770 transports the feeding tray 220 to the guide plate 780. Then, the guide plate 780 slides to one side.
