Description

Technical Field

[0001] The utility model relates to a low-temperature vacuum dehydration device, in particular to a low-temperature vacuum dehydration device for producing crisp fruits. Background Art

[0002] Fruit crisping involves crisping fruit. This process not only preserves the original color, aroma, and flavor, but also enhances rehydration and long-term shelf life. This method allows fruit products to be stored at room temperature for extended periods, facilitating transportation and sales, and increasing their market value and consumer acceptance.

[0003] Common crisping equipment includes vacuum freeze dryers, vacuum low-temperature fryers, and vacuum belt dehydrators. Vacuum freeze dryers produce crispy, dried fruits by directly sublimating the moisture from fruit at low temperatures. They are suitable for low-temperature vacuum dehydration of fruits, vegetables, and other ingredients. Vacuum low-temperature fryers and vacuum belt dehydrators are suitable for processes such as fruit and meat pressing and pure sweet potato drying.

[0004] When using a vacuum freeze dryer to crisp and dehydrate fruit, the operator places the pre-washed and cut fruit pieces on a plate, places the plate into the processing chamber of the vacuum freeze dryer, and starts the machine. The processing chamber is cooled and vacuumed using a low-temperature vacuum system module to dehydrate and dry the fruit pieces. After processing is complete, the operator removes the plate. The temperature of the inner wall of the processing chamber is relatively low, and the operator will inevitably come into contact with the inner wall when taking the plate, which can easily cause frostbite. The operator also needs to extend their arms into the processing chamber to facilitate taking or placing the plate. During this process, external contaminants may be brought into the processing chamber, making food safety accidents more likely to occur. Utility Model Content

[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0043] See also Figures 1 to 9 As an embodiment of the present invention, the low-temperature vacuum dehydration device for producing fruit crisps includes a chassis 1; and a first hinge block 101 and a low-temperature vacuum system module 102 fixedly mounted on the chassis 1;

[0044] A processing chamber 3 is fixedly installed in the chassis 1; a sealing door 2 is rotatably installed on the first hinge block 101; and multiple sets of storage plates 13 are provided in the processing chamber 3;

[0045] An auxiliary transport mechanism is provided on the chassis 1 ; when the sealed door 2 is rotated to open or close the chassis 1 , the auxiliary transport mechanism can drive the storage plate 13 to move outward or inward within the processing chamber 3 .

[0046] In this embodiment, the storage plate 13 is used to place fruit pieces; the fruit pieces are evenly spread on the storage plate 13, and then the storage plate 13 is placed in the processing chamber 3; the sealing door 2 is closed and the low-temperature vacuum system module 102 is started; the low-temperature vacuum system module 102 can evacuate the air in the processing chamber 3 and reduce the temperature in the processing chamber 3 to dehydrate and dry the fruit pieces.

[0047] Through the operation of the low-temperature vacuum system module 102, frozen crystals of water in fresh fruits and vegetables can be directly evaporated into water vapor under vacuum conditions for drying. This technology, performed at low temperatures, avoids thermal damage and oxidation of nutrients in fruits and vegetables, preserving the color, aroma, flavor, and heat-sensitive ingredients of the food to the greatest extent possible. It maintains their original properties, and the vacuum drying process, with minimal oxygen, protects easily oxidized substances.

[0048] After the dehydration of the fruit pieces is completed, an external force is applied to rotate the sealed door 2 away from the chassis 1 to open the processing chamber 3. During the rotation of the sealed door 2, the auxiliary transport mechanism is driven to move, and the auxiliary transport mechanism drives the storage plate 13 to move outward in the processing chamber 3, so that the storage plate 13 is partially exposed outside the processing chamber 3, making it convenient for the operator to carry the storage plate 13, thereby transporting the processed fruit pieces.

[0049] At the same time, when the placing plate 13 containing unprocessed fruit pieces is placed back into the processing chamber 3 for the next batch of dehydration processing, only part of the placing plate 13 needs to be extended into the processing chamber 3. After all the placing plates 13 are placed, the sealing door 2 rotates toward the chassis 1 when external force is applied to close the processing chamber 3. During the rotation, the auxiliary transport mechanism will drive the placing plate 13 to move inward in the processing chamber 3 so that the placing plate 13 can completely enter the processing chamber 3.

[0050] The processing chamber 3 is opened or closed by rotating the sealed door 2. During the rotation of the sealed door 2, the auxiliary transport mechanism drives the storage plate 13 to move outward and inward in the processing chamber 3, so as to facilitate the operator to transfer the fruit fragments, which can effectively improve the processing efficiency, and can prevent the low temperature inner wall of the processing chamber 3 from freezing to the operator after the low-temperature vacuum system module 102 is running, and can also effectively prevent the possibility of external pollutants entering the processing chamber 3 and contaminating the fruit.

[0051] As a further solution of the present invention, the auxiliary transport mechanism includes a second hinge block 4 fixedly mounted on the sealing door 2; a rotating rod 5 is rotatably mounted on the second hinge block 4; a protrusion 501 is fixedly mounted on the rotating rod 5; a slide plate 7 is slidably engaged with the processing chamber 3; a connecting rod 6 is fixedly mounted on the slide plate 7; a sliding groove 601 is provided on the connecting rod 6 for sliding engagement with the protrusion 501; a plurality of groups of push plates 8 cooperating with the storage plate 13 are provided in the processing chamber 3; a plurality of groups of push plates 8 are fixedly connected by a connecting plate 9; and one of the push plates 8 is fixedly connected to the slide plate 7.

[0052] In this embodiment, during the rotation of the sealed door 2, the rotating rod 5 rotates on the second hinge block 4. After the sealed door 2 rotates a certain angle, the rotating sealed door 2 drives the rotating rod 5 to rotate synchronously (with a different rotation center than the rotation on the second hinge block 4), thereby driving the protrusion 501 to rotate. The rotation of the protrusion 501 squeezes the connecting rod 6, driving the connecting rod 6 toward the sealed door 2. At the same time, the protrusion 501 slides in the sliding groove 601. The sliding plate 7 slides synchronously with the connecting rod 6, thereby driving the push plate 8 connected to it to move, and then driving all push plates 8 to move synchronously through the connecting plate 9. During the movement of the push plate 8, it will contact the storage plate 13, and after the contact, it will drive the storage plate 13 to move synchronously outward within the processing chamber 3. When the sealed door 2 is opened to a certain angle (which does not hinder the operator from taking the storage plate 13), part of the storage plate 13 is exposed outside the processing chamber 3, making it easier for the operator to take the storage plate 13 (through the exposed part). Since the operator does not come into contact with the processing chamber 3 during the taking process, frostbite can be effectively avoided, and external pollutants can also be effectively prevented from entering the processing chamber 3 and contaminating the fruit.

[0053] As a further solution of the present invention, the auxiliary transport mechanism also includes a column 901 slidably mounted on the connecting plate 9; a return spring 10 fixedly connected to the column 901 is fixedly mounted on the connecting plate 9; a lifting groove 902 is provided on the connecting plate 9; a cross bar 11 fixedly connected to the column 901 is slidably engaged in the lifting groove 902; a protruding column 1101 is fixedly mounted on the cross bar 11; a fixed plate 1301 cooperating with the protruding column 1101 is fixedly mounted on the storage plate 13; a fixed block 12 is fixedly mounted on the processing chamber 3; and a cooperating groove slidably cooperating with the column 901 is provided on the fixed block 12.

[0054] In this embodiment, during the process of opening the processing chamber 3, the connecting plate 9 will drive the column 901 to move synchronously, so that the column 901 slides in the matching groove. During the sliding process, the column 901 will move toward the bottom of the processing chamber 3 to drive the protruding column 1101 to move downward through the cross bar 11, so that the protruding column 1101 cannot cooperate with the fixed plate 1301.

[0055] The operator places the portion of the storage plate 13 refilled with fruit pieces into the processing chamber 3 and rotates the sealing door 2 to close the processing chamber 3; during the rotation of the sealing door 2, the rotating rod 5 will rotate on the second hinge block 4. After the sealing door 2 rotates to a certain angle, the sealing door 2 will drive the rotating rod 5 to rotate synchronously (different from the rotation center of the rotation on the second hinge block 4), thereby driving the protrusion 501 to rotate; when the protrusion 501 rotates, it will squeeze the connecting rod 6 and drive the connecting rod 6 to move away from the sealing door 2. At the same time, the protrusion 501 will slide in the slide groove 601; the slide plate 7 will slide synchronously with the connecting rod 6, thereby driving the push plate 8 connected to it to move, and driving all the push plates 8 to move synchronously through the connecting plate 9.

[0056] During the movement of the connecting plate 9 in the direction away from the sealing door 2, the column 901 will slide in the opposite direction in the mating groove. At this time, the elastic force of the return spring 10 will drive the column 901 to move toward the top of the processing chamber 3, so as to drive the cross bar 11 to slide upward on the lifting groove 902, thereby driving the protruding column 1101 to move upward. When the cross bar 11 reaches the end of the stroke, the protruding column 1101 can cooperate with the fixed plate 1301.

[0057] Continue to rotate the sealing door 2 to drive the protruding column 1101 to continue to move away from the sealing door 2 through the connecting plate 9. During the movement, the protruding column 1101 will conflict with the fixed plate 1301, and after the conflict, drive the fixed plate 1301 to move synchronously, thereby driving the storage plate 13 to move inward in the processing chamber 3; when the processing chamber 3 is closed, the storage plate 13 has all entered the processing chamber 3.

[0058] Since the operator does not come into contact with the processing chamber 3 during the placement process, the occurrence of frostbite can be effectively avoided, and external pollutants can be effectively prevented from entering the processing chamber 3 and contaminating the fruits.

[0059] As a further solution of the present invention, the mating groove includes a first straight groove 1201, an inclined groove 1202 and a second straight groove 1203; one end of the first straight groove 1201 is connected to the inclined groove 1202; the other end of the inclined groove 1202 is connected to one end of the second straight groove 1203.

[0060] In this embodiment, the horizontal height of the first straight groove 1201 is higher than the horizontal height of the second straight groove 1203 ; and the length of the second straight groove 1203 is very short.

[0061] When the sealed door 2 is rotated to open the processing chamber 3, the connecting plate 9 drives the column 901 toward the sealed door 2. The column 901 first slides in the first straight groove 1201, at which point the column 901 remains horizontal. As the column 901 slides in the inclined groove 1202, the squeeze of the inclined groove 1202 causes the column 901 to move toward the bottom of the processing chamber 3, driving the protruding column 1101 to move synchronously via the crossbar 11, while compressing the return spring 10. When the column 901 slides into the second straight groove 1203, the top surface of the protruding column 1101 is lower than the bottom surface of the fixed plate 1301. At this point, the protruding column 1101 is not obstructed when the storage plate 13 is removed or placed, making it easier for the operator to remove or place the storage plate 13. The column 901 remains horizontal while sliding in the second straight groove 1203.

[0062] After the storage plate 13 is re-placed (the fixed plate 1301 passes over the protruding column 1101, and the storage plate 13 conflicts with the push plate 8), when the sealing door 2 is rotated to close the processing chamber 3, the connecting plate 9 drives the column 901 to move away from the sealing door 2; the column 901 will first slide in the second straight groove 1203 toward the inclined groove 1202, at this time the horizontal height of the column 901 remains unchanged; then, the column 901 slides in the inclined groove 1202, and the elastic force of the reset spring 10 causes the column 901 to move toward the processing chamber 3. The top of the chamber 3 moves and always contacts the inclined groove 1202, thereby driving the protruding column 1101 to move synchronously; when the column 901 slides in the first straight groove 1201, the horizontal height of the column 901 remains unchanged; during this process, the horizontal height of the top of the protruding column 1101 is greater than the horizontal height of the bottom of the fixed plate 1301. It is estimated that the protruding column 1101 will contact the fixed plate 1301 and drive the fixed plate 1301 to move synchronously after the contact, so as to drive the storage plate 13 to move inward in the processing chamber 3.

[0063] As a further solution of the present invention, multiple groups of support plates 15 are fixed on the processing chamber 3; a guide rail 14 is provided on the support plate 15; a telescopic sleeve 1501 is fixedly installed on the support plate 15; a telescopic column 1401 slidingly engaged with the telescopic sleeve 1501 is fixedly installed on the guide rail 14; a buffer spring 16 is provided in the telescopic sleeve 1501; the two ends of the buffer spring 16 respectively contact the telescopic column 1401 and the support plate 15; a roller 1302 is rotatably installed on the storage plate 13 and rolls with the guide rail 14.

[0064] In this embodiment, the roller 1302 rolls on the guide rail 14 , which can reduce the resistance to the movement of the storage plate 13 .

[0065] When the roller 1302 contacts the guide rail 14, the gravity of the storage plate 13 drives the guide rail 14 toward the support plate 15. At this time, the telescopic column 1401 slides inward in the telescopic sleeve 1501, compressing the buffer spring 16. When the low-temperature vacuum system module 102 is in operation, the chassis 1 will vibrate at a high frequency and small amplitude. The elastic force of the buffer spring 16 can buffer and offset the vibration, thereby preventing the storage plate 13 from vibrating synchronously and causing the crisped fruit pieces to break.

[0066] As a further solution of the present invention, a first limit block 401 and a second limit block 402 are fixedly installed on the second hinge block 4; wherein, the first limit block 401 is arranged obliquely; and the second limit block 402 is perpendicular to the sealing door 2.

[0067] In this embodiment, when the sealed door 2 is rotated to open the processing chamber 3, the rotating rod 5 rotates on the second hinge block 4 toward the first limit block 401. During this process, the storage plate 13 does not move. When the rotating rod 5 contacts the first limit block 401, the rotating rod 5 will no longer be able to rotate with the second hinge block 4. At this time, the sealed door 2 drives the rotating rod 5 to rotate synchronously.

[0068] When the sealing door 2 is rotated to close the processing chamber 3, the rotating rod 5 separates from the first limit block 401 and rotates with the second hinge block 4. The rotating rod 5 rotates closer to the second limit block 402. During this process, the storage plate 13 does not move. When the rotating rod 5 contacts the second limit block 402, the rotating rod 5 will no longer be able to rotate with the second hinge block 4. At this time, the sealing door 2 drives the rotating rod 5 to rotate synchronously.

[0069] The first limiting block 401 limits the second limiting block 402 on the rotating rod 5 , so that the rotation angle of the sealing door 2 can be increased when the storage plate 13 is exposed outside the processing chamber 3 , making it easier for operators to take or place the storage plate 13 .

[0070] As a further solution of the present invention, a tempered glass 201 and a protective net 202 are fixedly mounted on the sealed door 2 .

[0071] In this embodiment, when processing fruit pieces, the progress of the fruit pieces becoming brittle is monitored through the tempered glass 201; the tempered glass 201 is protected by the protective net 202 to prevent the tempered glass 201 from being broken due to collision.

[0072] The above embodiments are exemplary rather than restrictive, so any technical solution of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention is included in the present invention.
