Abstract
Description
Technical Field
[0001] This utility model relates to the field of fruit deep processing technology, specifically to a freeze-dried fruit powder production device. Background Technology
[0002] Freeze-dried fruit powder is a powdered food product made from fresh fruit using freeze-drying technology. Under low temperature and low pressure, the water in the fruit is directly sublimated from a solid state to a gaseous state, thus removing moisture and preserving the fruit's nutrients, color, and flavor to the maximum extent. To prepare freeze-dried fruit powder, the fruit is first crushed or made into a pulp, then placed in a cold storage to freeze the internal moisture into ice, and finally fed into a fruit and vegetable freeze dryer for freeze-drying.
[0003] The entire freeze-drying process generally involves laying the material in a tray and then placing the tray on a tray rack. When the tray is transferred from the cold storage to the freeze dryer, there are two main methods in the existing technology: (1) Use a trolley to push the tray rack in the cold storage to the side of the freeze dryer, turn on the freeze dryer, and manually move the tray to the tray rack in the freeze dryer. This method is relatively labor-intensive; (2) Lay hanging rails in the cold storage, freeze dryer and workshop, and the top of the tray rack is suspended on the hanging rails by pulleys. When transferring, the tray rack can be pushed from the cold storage to the freeze dryer as a whole. This method has a long hanging rail laying distance and relatively high construction cost.
[0004] To balance ease of transfer and cost-effectiveness, the applicant designed a rapid loading device. Its main structure consists of rollers at the four corners of a pallet frame and multiple pairs of clamping wheels at the center of the bottom. The entire pallet frame rests on a trolley, which has a central guide rail corresponding to the clamping wheels, side guide rails corresponding to the bottom rollers, and a removable locking mechanism on the bottom frame of the pallet frame. To integrate this rapid loading device, corresponding modifications to the internal structure of the freeze dryer are required.
[0005] In order to solve the above problems, people have been seeking an ideal technological solution. Summary of the Invention
[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a freeze-dried fruit powder production device that can work in conjunction with the fast feeding device in the prior art, thereby balancing the convenience of transfer and economy.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a freeze-dried fruit powder production device, comprising a cylindrical horizontal freeze-drying chamber and a negative pressure pipe connected to the horizontal freeze-drying chamber. The inner wall of the horizontal freeze-drying chamber is provided with clamping guide rails extending along the axial direction and four corner guide rails. The clamping guide rails are located at the bottom center of the horizontal freeze-drying chamber, and clamping wheel guide surfaces are provided on both side walls of the clamping guide rails. The guide surfaces of the four corner guide rails are all planar and have a centrally symmetrical structure. The guide surfaces of the two upper corner guide rails face directly downwards, and the guide surfaces of the two lower corner guide rails face directly upwards. A chamber door space is provided at the opening of the horizontal freeze-drying chamber by the clamping guide rails and the four corner guide rails.
[0008] Based on the above, the clamping guide rail is arranged such that the two side walls of one end near the opening of the horizontal freeze-drying chamber converge towards the middle to form an inlet narrow head.
[0009] Based on the above, each corner guide rail is inclined outward at the end closest to the horizontal freeze-drying chamber opening to form an inlet slope.
[0010] Based on the above, it also includes two purging pipes, which are arranged on both sides of the inner wall of the horizontal freeze-drying chamber. The air inlet of the purging pipe is connected to an external blowing device. Several nozzles are arranged on the pipe wall of the purging pipe, and the nozzles are arranged facing the guide surfaces of the two corner guide rails below.
[0011] Based on the above, several of the nozzles are inclined toward the opening of the horizontal freeze-drying chamber.
[0012] This utility model has substantial features and advancements compared to existing technologies. Specifically, it can be used in conjunction with the quick loading device described in the prior art. The clamping guide rail can connect with the middle guide rail on the trolley, and the two lower corner guide rails connect with the side guide rails on the trolley. This allows the pallet frame to be pushed in and out of the horizontal freeze-drying chamber as a whole. After entering the chamber, the clamping guide rail supports the clamping wheels at the bottom of the pallet frame, controlling the pallet frame to be centered horizontally. The four corner guide rails support the rollers at the four corners of the pallet frame, controlling the pallet frame to be centered vertically. It can cooperate with the quick loading device described in the prior art, thus combining the advantages of convenient transfer and economy.
[0013] Furthermore, the inclusion of the narrow guide head and the inclined guide surface reduces the accuracy requirements for docking with the pallet rack, making operation easier for staff.
[0014] Furthermore, the blowing pipe facilitates the blowing of the two lower corner guide rails, preventing powder and other debris from falling onto the guide rail surface and affecting the smooth sliding of the pallet frame; the nozzle is tilted towards the opening of the horizontal freeze-drying chamber, which can gradually blow powder and other debris out of the opening, eliminating the need for manual cleaning inside the chamber.

[0020] The technical solution of this utility model will be further described in detail below through specific embodiments. Example 1
[0021] like Figure 1-3 As shown, a freeze-dried fruit powder production device includes a cylindrical horizontal freeze-drying chamber 1 and a negative pressure pipe 2 connected to the horizontal freeze-drying chamber 1. The inner wall of the horizontal freeze-drying chamber 1 is provided with clamping guide rails 3 extending along the axial direction and four corner guide rails 4. The clamping guide rails 3 are located at the bottom center of the horizontal freeze-drying chamber 1, and clamping wheel guide surfaces are provided on both side walls of the clamping guide rails 3. The guide surfaces of the four corner guide rails 4 are all planar and have a centrally symmetrical structure. The guide surfaces of the two upper corner guide rails 4 face directly downwards, and the guide surfaces of the two lower corner guide rails 4 face directly upwards. A chamber door space is provided at the opening of the horizontal freeze-drying chamber 1 by the clamping guide rails 3 and the four corner guide rails 4 for closing the chamber door.
[0022] Working principle:
[0023] This freeze-dried fruit powder production device is used in conjunction with the quick feeding device described in the background technology. The clamping guide rail 3 can be connected to the middle guide rail on the trolley, and the two lower corner guide rails 4 are connected to the side guide rails on the trolley. This allows the pallet frame 5 to be pushed in and out of the horizontal freeze-drying chamber 1 as a whole. After entering the chamber, the clamping wheels 6 at the bottom of the pallet frame 5 clamp the clamping wheel guide surfaces on both sides of the clamping guide rail 3, controlling the pallet frame 5 to be centered left and right. The rollers 7 at the four corners of the pallet frame 5 contact the guide surfaces of the four corner guide rails 4, controlling the pallet frame 5 to be centered up and down.
[0024] To facilitate alignment, the two side walls of the clamping guide rail 3 near the opening of the horizontal freeze-drying chamber 1 converge towards the middle to form an inlet narrow head 31. The corner guide rail 4 near the opening of the horizontal freeze-drying chamber 1 is inclined outward to form an inlet slope 41. The inlet narrow head 31 and the inlet slope 41 can guide the pallet rack 5 into the area to automatically align, reduce the accuracy requirements for docking with the pallet rack, and make it easier for operators to operate. Example 2
[0025] like Figure 4 As shown, the freeze-dried fruit powder production device also includes two purging pipes 8, which are arranged on both sides of the inner wall of the horizontal freeze-drying chamber 1. The air inlet of the purging pipe 8 can pass through the side wall of the cylinder or the closed end and be connected to an external blowing device. The purging pipe 8 extends along the axial direction of the horizontal freeze-drying chamber 1. Several nozzles 9 are arranged on the pipe wall of the purging pipe 8, and the nozzles 9 are arranged facing the guide surfaces of the two lower corner guide rails 4. The nozzles 9 are used to purge the two lower corner guide rails 4 to prevent powder and other debris from falling onto the guide rail surface and affecting the smooth sliding of the tray frame 5.
[0026] To further reduce the amount of manual cleaning, several of the nozzles 9 are inclined toward the opening of the horizontal freeze-drying chamber 1. By controlling the airflow, powder and other impurities can be gradually blown out of the opening, eliminating the need for manual cleaning inside the chamber.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
