Description

Technical Field

[0001] This disclosure pertains to the field of low-temperature cryogenic storage, specifically relating to a cryopreservation machine. Background Technology

[0002] Low-temperature freezing storage technology is widely used for long-term preservation of food, biological samples, and other fields. It is especially effective for perishable fruits such as lychees, as rapid freezing and a stable low-temperature environment can effectively extend their shelf life. Existing freezing equipment usually immerses the material directly in a coolant to achieve rapid cooling, but the process of removing the material, especially for loosely placed materials such as lychees, is inconvenient and inefficient.

[0003] Specifically, when lychees are placed into the freezing machine in a loose state, they need to be scooped out one by one from the coolant when they are taken out. This is not only cumbersome, but also causes the coolant to be stirred up during the scooping process, resulting in collisions between lychees or between lychees and the inner wall of the container, causing mechanical damage and affecting product quality. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this disclosure is to provide a freezing machine that solves the problems of low operating efficiency caused by the need to scoop out scattered materials one by one from the coolant, and mechanical damage caused by materials colliding with each other or hitting the inner wall of the container due to fluid disturbance.

[0005] The objective of this disclosure can be achieved through the following technical solutions: A cryogenic chamber includes: a cryogenic chamber for storing coolant and a support component; The inner side of the freezing chamber is provided with a support for holding materials, and the side wall of the support is provided with a filter hole for the coolant to flow out. The sidewall of the bearing member is slidably provided with a closing component; The closing component has a closed state and an open state by sliding relative to the carrier; In the closed state, the closing assembly and the carrier together form a heat-insulating cavity that can reduce heat exchange between the inside and outside of the carrier; When in the open state, the closing assembly, in conjunction with the carrier and the filter hole, allows only the coolant inside the cavity to flow out.

[0006] In some disclosures, the closure assembly includes a sealing plate, the inner bottom surface of the cryosleep chamber is fixed with the sealing plate, and the position of the sealing plate corresponds to the position of the carrier. The side wall of the carrier is fixed with a first guide rail adapted to the sealing plate, and the inner side of the first guide rail is provided with a guide groove. The carrier is slidably connected to the sealing plate through the first guide rail.

[0007] In some disclosures, the sidewall of the sealing plate is watertightly fitted with the guide groove.

[0008] In some disclosures, when the upper end face of the sealing plate is in contact with the upper end of the guide groove, the sealing plate blocks the outside of the filter hole, and the carrier is in a closed state; when the upper end face of the sealing plate is located at the lower end of the guide groove, the filter hole is completely exposed.

[0009] In some disclosures, the diameter of the filter pores is smaller than the diameter of the lychee.

[0010] In some disclosures, a support plate is slidably provided on the outer wall of the sealing plate, and a first limiting block is fixed at the upper end of the support plate. A second guide rail is fixed on the bottom surface of the first guide rail, and the second guide rail is perpendicular to the first guide rail. The first limiting block passes through the second guide rail.

[0011] In some disclosures, the first limiting block is disposed through the second guide rail, and a second limiting block is fixed at one end of the first limiting block that passes through the second guide rail, and the width of the second limiting block is greater than the width of the second guide rail.

[0012] In some disclosures, the sealing plate, the sidewalls of the bearing member, and the bottom plate are all heat-insulating sandwich panels.

[0013] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows: A fixed connection refers to a connection in which parts or components are fixed in place and there is no relative movement between them; A rotating connection is a connection between parts that allows the parts to rotate relative to each other. Threaded connections are a type of detachable fixed connection with advantages such as simple structure, reliable connection, and convenient assembly and disassembly. They are widely used in mechanical engineering and connection structure fields. A sliding connection is a connection between parts that allows the parts to slide against each other.

[0014] The beneficial effects of this disclosure are: 1. By lifting and removing the carrier and the material together, and filtering out the coolant during the removal process, it helps to solve the inconvenience of picking up scattered lychees in the liquid. Furthermore, by separating the coolant from the lychees, it helps to reduce the situation where the lychees collide with each other or with the inner wall of the carrier due to the agitation of the fluid. 2. The carrier and the closing assembly together form a heat-insulating cavity that reduces the mixing of coolant inside and outside the carrier. When the freezer faces a sudden power outage or equipment movement, the heat-insulating cavity helps to slow down the mixing rate of the internal and external coolant, thereby delaying the rise in the temperature of the coolant around the lychee and providing a longer low-temperature environment for the lychee in the event of a sudden power outage.

[0018] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0019] Please refer to Figures 1 to 6 A cryopreservation machine includes: a cryopreservation chamber 1 for storing coolant and a support member 2; The inner side of the freezing chamber 1 is provided with a support member 2 for holding materials, and the side wall of the support member 2 is provided with a filter hole 21 for the coolant to flow out. The side wall of the support member 2 is slidably provided with a closing component 3; The closing component 3 has a closed state and an open state by sliding relative to the carrier 2; In the closed state, the closing component 3 and the carrier 2 together form a heat-insulating cavity 22 that can reduce heat exchange between the inside and outside of the carrier 2; When in the open state, the closing component 3 cooperates with the carrier 2 and the filter hole 21, allowing only the coolant inside the receiving cavity to flow out.

[0020] When in use, the carrier 2 is filled with loose lychees. Then, when the carrier 2 is placed in the frozen chamber 1 in a closed state, coolant is added to the frozen chamber 1 so that the coolant completely covers the carrier 2. At this time, the coolant in the frozen chamber 1 is divided into two parts by the carrier 2 and the closing component. One part is located in the heat insulation cavity 22 inside the carrier 2 and the closing component 3, and the other part is located between the outer wall of the carrier 2 and the frozen chamber 1. When it is necessary to remove the lychees, since they are in a scattered state, scooping them out will disturb their position within the support member 2. In this case, move the support member 2 upwards as a whole until it is removed from the freezing chamber 1. Please refer to [reference needed]. Figure 6 During this process, the closing component 3 and the carrier 2 gradually change from the closed state to the open state. The coolant in the carrier 2 flows out through the filter hole 21 into the freezing chamber 1. After all the coolant in the insulation chamber 22 has flowed out, the lychees are scattered in the carrier 2, so that the loose lychees can be taken out. When taking out the lychees in this state, since there is no interference from other coolant, the staff can reduce the disturbance to the position of the other lychees by handling them gently.

[0021] Meanwhile, the support component 2 is equipped with a heat insulation cavity 22. When the freezing machine suddenly loses power, it separates the coolant around the lychee from the coolant in the other cold areas. When the freezing machine moves due to a change in position, the support component 2 and the closing component 3 prevent the coolant in the heat insulation cavity 22 from mixing with the coolant outside, thereby reducing the temperature rise of the coolant around the lychee. This helps to maintain the temperature of the coolant around the lychee and the lychee itself for a short time during a power outage, which helps to reduce the deterioration of the lychee due to its rapid temperature rise.

[0022] The insulation chamber 22 opens and closes in conjunction with the carrier 2 and the closing assembly 3, allowing the coolant within the insulation chamber 22 to be reset each time lychees are removed. Specifically, when the closing assembly 3 opens to remove processed lychees, the partially heated coolant in the insulation chamber 22 is discharged; when the closing assembly 3 closes to receive a new batch of lychees, the insulation chamber 22 is refilled with fresh, temperature-controlled coolant from the main body of the freezing chamber 1. This "resetting" mechanism helps reduce the cross-influence of the "thermal history" remaining from the previous batch of materials on the next batch, thereby improving the uniformity and stability of product quality.

[0023] Please refer to Figures 2 to 4The closing component 3 includes a sealing plate 31. The sealing plate 31 is fixed on the inner bottom surface of the cryopreservation chamber 1, and the position of the sealing plate 31 corresponds to the position of the support member 2. The side wall of the support member 2 is fixed with a first guide rail 32 that is adapted to the sealing plate 31, and a guide groove 33 is opened on the inner side of the first guide rail 32. The support member 2 is slidably connected to the sealing plate 31 through the first guide rail 32. In use, multiple first guide rails 32 are fixed to the side wall of the carrier 2, and the side wall of the sealing plate 31 of the first guide rail 32 is slidably installed in the guide groove 33 of the first guide rail 32. The first guide rail 32 restricts the movement path of the carrier 2, so that the closing component 3 closes from bottom to top on the outside of the carrier 2 with filter holes 21 during the sliding of the carrier 2 along the first guide rail 32, thereby blocking the filter holes 21 and forming a sealed space with closed sides and bottom inside the carrier 2, thereby separating the coolant inside the carrier 2 from the coolant outside the carrier 2.

[0024] The cooperation between the first guide rail 32 and the sealing plate 31 can guide the carrier 2 to move accurately to the side wall of the cryosleep chamber 1.

[0025] Meanwhile, the side wall of the sealing plate 31 and the guide groove 33 are watertight, which can improve the sealing performance of the connection between the closing assembly 3 and the carrier 2 in the insulation cavity 22.

[0026] Please refer to Figures 1 to 2 When the upper end face of the sealing plate 31 is in contact with the upper end of the guide groove 33, the sealing plate 31 blocks the outside of the filter hole 21, and the carrier 2 is in a closed state; when the upper end face of the sealing plate 31 is located at the lower end of the guide groove 33, the filter hole 21 is completely exposed.

[0027] The sealing plate 31 is fixed in the freezing chamber 1 beforehand, and the inner wall of the guide groove 33 is used to fit with the sealing plate 31 to restrict the position of the carrier 2 in the freezing chamber 1, which helps to improve the stability of the carrier 2. When the freezing machine moves, the cooperation between the sealing plate 31 and the guide groove 33 restricts the movement of the carrier 2, which helps to reduce the situation of lychees hitting the inner wall of the carrier 2.

[0028] Meanwhile, since the sealing plate 31 is fixed inside the freezing chamber 1, when the carrier 2 is taken out upward, the filter hole 21 on the upper side of the carrier 2 is separated from the sealing plate 31 first. At this time, the coolant flows out from the upper filter hole 21 first. When the sealing plate 31 moves to the end of the guide groove 33, the filter hole 21 is fully opened, thereby filtering out the coolant in the carrier 2. In some embodiments, the filter hole 21 and the closing component 3 are disposed directly below the support member 2. When the support member 2 is lifted upward, the liquid loss rate inside the support member 2 can be accelerated compared to the filter hole 21 being opened on the side wall of the support member 2. When the filter hole 21 is opened on the side wall, the filter hole 21 is exposed from top to bottom, which is conducive to the coolant in the support member 2 flowing out from top to bottom and generating laminar flow. Compared with the case where the filter hole 21 is opened on the bottom surface of the support member 2, the coolant flows out more slowly and steadily, which is conducive to further reducing the disturbance to the position of the lychee when the water flows out.

[0029] Please refer to Figure 2 The diameter of the filter hole 21 is smaller than the diameter of the lychee; to prevent the lychee from flowing out of the filter hole 21.

[0030] Please refer to Figures 3 to 5 A support plate 4 is slidably provided on the outer wall of the sealing plate 31, and a first limiting block 41 is fixed at the upper end of the support plate 4. A second guide rail 5 is fixed on the bottom surface of the first guide rail 32, and the second guide rail 5 is perpendicular to the first guide rail 32. The first limiting block 41 is provided through the second guide rail 5.

[0031] The support plate 4 can slide vertically along the outer wall of the sealing plate 31. When the second guide rail 5 moves to the upper end of the sealing plate 31, the sealing plate 31 disengages from the first guide rail 32. At this time, the restriction of the sealing plate 31 on the first guide rail 32 in the horizontal direction disappears. The carrier 2 is then dragged horizontally, and the first limiting block 41 slides towards the second guide rail 5, thereby restricting the lateral movement trajectory of the carrier 2. Then, the side of the carrier 2 away from the sealing plate 31 is placed on the outer wall of the freezing chamber 1. At this time, the force points on the bottom surface of the carrier 2 are the sealing plate 31 and the freezing chamber frame, respectively, so as to temporarily fix the carrier 2, which facilitates the drainage of water in the carrier 2 back into the freezing chamber and also facilitates the removal of lychees in the carrier 2.

[0032] Please refer to Figure 5 The first limiting block 41 is set through the second guide rail 5, and the first limiting block 41 is fixed to the second limiting block 42 at one end through the second guide rail 5, and the width of the second limiting block 42 is greater than the width of the second guide rail 5.

[0033] The second limiting block 42 fixes the support plate 4 and the second guide rail 5 in the vertical direction. When the second guide rail 5 moves upward, the second limiting block 42 abuts against the second guide rail 5 and pushes the second limiting block 42 to move upward. The limiting block makes the support plate 4 move up and down with the support frame. When the support member 2 moves horizontally, the first limiting block 41 is transported to the working position.

[0034] To facilitate sealing the upper end of the freezing chamber 1 with the sealing cap, the height of the support member 2 is usually lower than the height of the outer wall frame of the freezing chamber 1. The support plate 4 slides upward along the sealing plate 31 and stops at the upper end of the sealing plate 31 to compensate for the height difference between the upper end face of the outer wall frame of the freezing chamber 1 and the upper end face of the sealing plate 31. This allows the support frame to be temporarily stopped outside the freezing chamber 1 without human support, which makes it easier to put in and take out lychees.

[0035] The side walls and bottom plate of the sealing plate 31, the bearing member 2, and the sealing plate are all heat-insulating sandwich panels.

[0036] The heat-insulating sandwich panel is a vacuum heat-insulating panel, a sandwich panel filled with foam insulation material, or an aerogel composite material panel.

[0037] It can reduce the agitation of coolant around the lychee while also reducing the temperature transfer of coolant inside and outside the cavity.
