Description

Technical Field

[0001] This utility model relates to the field of freeze-dried fruit foods, and in particular to a vacuum freeze dryer for processing freeze-dried fruit foods. Background Technology

[0002] Freeze-dried fruits are made by freezing fresh fruits at low temperatures and then dehydrating and drying them in a vacuum environment. Through freeze-drying technology, the water in the fruit sublimates and is removed, preserving its natural color, nutrients, and flavor, resulting in a crisp and light texture. The finished product can be stored for a long time without preservatives, and after rehydration, it is almost in the same state as fresh fruit, making it easy to carry. It is commonly used as a snack, in baking, or as a meal replacement, aligning with healthy eating trends.

[0003] Heating and drying is a key step in the processing of freeze-dried fruit products. However, the heating trays for most freeze-dried fruit products are difficult to disassemble and reassemble quickly. After long-term use, the trays are prone to leaving behind fruit pulp fragments after heating. If they are not removed and cleaned in time, it will affect the quality of subsequent products. In addition, the electrical control boxes of some devices are set in a relatively fixed position and are difficult to move flexibly, which leads to inconvenience in maintenance and reduces the practicality of the device.

[0004] Therefore, those skilled in the art have provided a vacuum freeze dryer for processing freeze-dried fruit foods to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a vacuum freeze dryer for processing fruit freeze-dried foods. The device completes the initial installation and positioning by sliding the tray into the drying chamber so that the middle part of one end face of the mounting plate is aligned with the axis of the hook rod on the fixing part. Then, the sliding rod is pushed so that the hook rod at one end passes through the through groove on the mounting plate. Then, it is twisted 90 degrees and pulled back so that it is engaged with the slot. Finally, the fixing bolt is twisted so that its lower end passes through the middle of the upper end face of the fixing part and engages with the middle of one side of the outer wall of the sliding rod. This facilitates the disassembly and maintenance of the tray and improves the practicality of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A vacuum freeze dryer for processing freeze-dried fruit foods includes a box body, a box door, a drying chamber, an electric heating plate, a tray, a placement chamber, and an electrical control box. Multiple quick disassembly and assembly mechanisms are fixedly connected to one side of the inner wall of the box body, and convenient maintenance mechanisms are fixedly connected to both sides of the lower end of one side of the box body. The quick assembly / disassembly mechanism includes multiple fixing parts. Each fixing part has a slot on both sides of one end face. A fixing bolt is threaded to the middle of the upper end face of the fixing part. A sliding rod is slidably connected to the middle of one end face of the fixing part. A hook rod is rotatably connected to one end of the sliding rod. Mounting plates are fixedly connected to both ends of one end face of the tray. A through groove is opened in the middle of one end face of the mounting plate. Slots are opened on both sides of one end face of the mounting plate. Through the above technical solution, the device completes the initial installation and positioning by sliding the tray into the drying chamber so that the middle part of one end face of the mounting plate is aligned with the axis of the hook rod on the fixing part. Then, the sliding rod is pushed so that the hook rod at one end passes through the through groove on the mounting plate. Then, the hook rod is twisted 90 degrees and pulled back so that it is engaged with the slot. Finally, the fixing bolt is twisted so that its lower end passes through the middle of the upper end face of the fixing part and engages with the middle of the outer wall of the sliding rod. This facilitates the disassembly and maintenance of the tray and improves the practicality of the device.

[0007] Furthermore, the convenient maintenance mechanism includes two connecting parts. A knob is rotatably connected to the middle of one side end face of the connecting part. A locking rod is fixedly connected to one end of the outer wall of the knob. A locking ring is fixedly connected to one end of the locking rod. A sliding groove is opened in the middle of one side end face of the connecting part. A spring is fixedly connected to one end of the outer wall of the sliding groove. A locking block is fixedly connected to one end of the spring. A plug-in groove is opened at one end of one side end face of the connecting part. Hook blocks are fixedly connected to both sides of the lower end of one side end face of the electrical control box. Through the above technical solution, the device slides the repaired electrical control box into the placement chamber at the lower end of the box to complete the initial docking of its upper hook block with the upper insertion slot of the connecting part. Then, the knob is turned to rotate the connecting rod and the retaining ring at a certain angle until one end of the retaining ring passes through one end of the side face of the insertion slot and forms a locking connection with one end of the side face of the hook block. At the same time, the retaining block loses the obstruction of the retaining ring and uses the elasticity of the spring to pop out part of the sliding groove, thereby blocking one end of the retaining rod and preventing the retaining ring from reversing. The electrical control box can be removed from the box for maintenance and repair at any time, which improves the practicality of the device.

[0008] Furthermore, a drying chamber is provided at the upper end of one side face of the box, and multiple electric heating plates are provided on the inner wall of the drying chamber; Through the above technical solution, the drying chamber is used to hold trays and uses electric heating plates to allow the fruits placed inside to lose moisture at high temperatures.

[0009] Furthermore, the inner wall of the drying chamber is slidably connected to multiple trays, and a placement chamber is opened at the lower part of one side end face of the box body. An electrical control box is slidably connected to the bottom surface of the inner wall of the placement chamber. With the above technical solution, the tray is used to hold the fruit, and the storage room is used to store the electrical control box so that it can be easily pulled out for inspection and maintenance at any time.

[0010] Furthermore, the lower end of the fixing bolt passes through the middle of the upper end face of the fixing part and forms a locking connection with the middle of one side of the outer wall of the slide rod, and one end of the hook rod forms a locking connection with the bayonet. Through the above technical solution, the fixing bolt can use the fixing part as a fixing fulcrum to lock the slide rod, preventing the hook rod from detaching from the mounting plate as the slide rod slides. The locking slot is used to store the hook rod during non-fixed periods, avoiding excessive extension of the hook rod that would affect the sliding of the tray into the drying chamber.

[0011] Furthermore, one end of the hook rod passes through the middle of one end face of the mounting plate and engages with the slot; Through the above technical solution, the hook rod passes through the mounting plate to initially make contact with the pallet, and then engages with the slot on the mounting plate to completely fix it to the pallet.

[0012] Furthermore, the locking block forms a sliding connection with one side of the outer wall of the slide groove, and one end of the locking ring passes through one end of one side face of the insertion groove and forms a locking connection with one end of one side face of the hook block; Through the above technical solution, the locking block can slide smoothly out of the slide groove, and the locking ring is restricted by the inner wall of the slide groove to prevent the locking ring from separating from the hook block.

[0013] This utility model has the following beneficial effects: 1. This utility model proposes a vacuum freeze dryer for processing freeze-dried fruit foods. The device completes the initial installation and positioning by sliding the tray into the drying chamber so that the middle part of one end face of the mounting plate is aligned with the axis of the hook rod on the fixing part. Then, the sliding rod is pushed so that the hook rod at one end passes through the through groove on the mounting plate. Then, the hook rod is twisted 90 degrees and pulled back so that it is engaged with the slot. Finally, the fixing bolt is twisted so that its lower end passes through the middle of the upper end face of the fixing part and engages with the middle of the outer wall of the sliding rod. This facilitates the disassembly and maintenance of the tray and improves the practicality of the device.

[0014] 2. This utility model proposes a vacuum freeze dryer for processing freeze-dried fruit foods. The device achieves initial docking between the hook block and the insertion slot on the connecting part by sliding the repaired electrical control box into the placement chamber at the lower end of the box. Then, the knob is turned to rotate the connecting rod and the retaining ring by a certain angle until one end of the retaining ring passes through one end of the insertion slot and forms a locking connection with one end of the hook block. At the same time, the block loses the obstruction of the retaining ring and is partially ejected from the sliding groove by the elasticity of the spring, thereby blocking one end of the rod and preventing the retaining ring from reversing. The electrical control box can be removed from the box for maintenance and repair at any time, which improves the practicality of the device. Attached Figure Description
