Description

Technical Field

[0001] The utility model relates to the technical field of fruit and vegetable freeze-drying, in particular to fruit and vegetable freeze-drying equipment based on FD freeze-drying technology. Background Art

[0002] Fruit and vegetable freeze-drying equipment is a kind of equipment specially used for processing fruits, vegetables and other foods. It removes moisture from fruits and vegetables through freeze-drying technology, thereby extending the shelf life and maintaining the nutritional content and taste of the food.

[0003] After searching, it was found that when using fruit and vegetable freeze-drying equipment, most fruits and vegetables are placed on multiple groups of trays, and then placed one by one in the freeze-drying chamber for freeze-drying. However, there are certain defects in actual use. When taking the trays out of the freeze-drying chamber one by one, the operator usually needs to wear thick cold-proof gloves, which will reduce the flexibility of operation, make it difficult to accurately control the movement of the trays, and increase the difficulty of operation. Therefore, it is necessary to redesign a fruit and vegetable freeze-drying equipment based on FD freeze-drying technology to address the above problems. Utility Model Content

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a fruit and vegetable freeze-drying equipment based on FD freeze-drying technology.

The outer walls of the sealed door panels are fixedly connected to multiple sets of trays and a single set of bottom plates. The inner wall of the freeze-drying chamber is fixedly connected to a sleeve. A connecting rod is slidably connected to the sleeve. A push plate is fixedly connected to the end of the connecting rod. The outer wall of the push plate is in contact with the side walls of the multiple sets of trays. An ejection mechanism for pushing the trays to slide outward is installed in the sleeve. A rotation groove is provided at the bottom of the freeze-drying chamber. A limiting mechanism for limiting the position of the multiple sets of trays is installed in the rotation groove.

[0007] Preferably, the ejection mechanism includes a slide plate slidably connected to the sleeve, a spring is fixedly connected to the inner wall of the sleeve, and the other end of the spring is fixedly connected to the slide plate.

[0020] 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.

[0021] Reference Figure 1-4A fruit and vegetable freeze-drying equipment based on FD freeze-drying technology includes a freeze-drying bin 1 and two sets of sealed door panels 4. The outer wall of the freeze-drying bin 1 is provided with two sets of freeze-drying chambers 2. The inner walls of the two sets of sealed door panels 4 are in contact with the outer wall of the freeze-drying bin 1. The outer wall of the sealed door panel 4 is fixedly connected to multiple sets of trays 5 and a single set of bottom plates 6. The inner wall of the freeze-drying chamber 2 is fixedly connected to a sleeve 10. A connecting rod 15 is slidably connected in the sleeve 10. A push plate 14 is fixedly connected to the end of the connecting rod 15. The outer wall of the push plate 14 is in contact with the side walls of the multiple sets of trays 5. An ejection mechanism that pushes the trays 5 to slide outward is installed in the sleeve 10. A rotating groove is provided at the bottom of the freeze-drying chamber 2. A limiting mechanism for limiting the position of multiple groups of trays 5 is installed in the rotating groove, and the ejection mechanism includes a slide plate 12 slidably connected to the sleeve 10, and a spring 11 is fixedly connected to the inner wall of the sleeve 10, and the other end of the spring 11 is fixedly connected to the slide plate 12; with the help of the sliding of the sealing door panel 4, multiple groups of trays 5 can be placed inside the freeze-drying chamber 2 at one time. During the sliding process of the tray 5, the spring 11 in the sleeve 10 is compressed. When the tray 5 is taken out, the spring 11 is reset, driving the multiple groups of trays 5 to slide outward a distance, thereby reducing the need for heavy protective equipment and increasing the flexibility of operation.

[0022] The limiting mechanism includes a rotating shaft 8 rotatably connected in the rotating groove, a slot 7 is provided at the bottom of the base plate 6, a blocking block 9 is fixedly connected to the outer wall of the rotating shaft 8, the outer wall of the blocking block 9 contacts the inner wall of the slot 7, the outer wall of the freeze-drying chamber 1 is rotatably connected to the turning handle 3, the turning handle 3 is coaxially fixedly connected to the rotating shaft 8, a limiting ring 13 is fixedly connected at the mouth of the sleeve 10, the inner diameter of the limiting ring 13 is smaller than the diameter of the slide 12, the side wall of the slide 12 contacts the inner wall of the sleeve 10, and the outer wall of the blocking block 9 is fan-shaped.

[0023] In the present invention, when the device is used specifically: the operator places the pre-processed fruits and vegetables on multiple trays 5, and slides multiple groups of trays 5 into the freeze-drying chamber 2 at one time by sliding the sealing door panel 4. During the sliding process, the side wall of the tray 5 contacts the push plate 14, and the push plate 14 compresses the spring 11 in the sleeve 10 to store elastic potential energy and prepare for the reset action of the tray 5. When the tray 5 slides to the specified position, the handle 3 is turned to insert the card block 9 into the card slot 7 of the bottom plate 6, locking the position of the tray 5 to prevent the tray 5 from accidentally moving or sliding during the freeze-drying process.

[0024] After the set time, the freeze-drying process is completed, and the operator turns the handle 3 to release the lock of the card block 9 on the card slot 7, unlocking the tray 5. The spring 11 has been compressed when the tray 5 slides in, and the restoring force of the spring 11 pushes the tray 5 to slide outward through the slide plate 12, so that the multiple groups of trays 5 are automatically pushed outward and exposed outside the freeze-drying chamber 2. At this time, the operator does not need to go deep into the freeze-drying chamber 2, but only needs to grab the tray 5 that has slid out partially, and can easily take out multiple groups of trays 5 at the same time, reducing manual handling and dependence on heavy cold-proof gloves, and improving the flexibility and convenience of operation.

[0025] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
