Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a vacuum drying device for food production. Background Technology

[0002] As an important part of convenient catering, Chinese fast food's core lies in achieving rapid meal preparation while maintaining traditional flavor through standardized processes. Vacuum drying technology, due to its low-temperature and low-oxygen characteristics, effectively avoids nutrient loss and flavor degradation caused by high temperatures, making it a key processing method for Chinese fast food ingredients.

[0003] The food vacuum low-temperature drying equipment with publication number CN209197311U includes a base plate. Its features include: a motor fixed to the upper side of the base plate; the motor's shaft fixedly connected to one end of a connecting block; a first round shaft fixed to the other end of the connecting block; the other end of the first round shaft hinged to one end of a connecting plate; the other end of the connecting plate fixedly connected to one end of a second round shaft; the other end of the second round shaft hinged to the middle of a triangular connecting plate; a third round shaft hinged to the upper end of the triangular connecting plate; and the other end of the third round shaft fixedly connected to the upper end of a column. This equipment minimizes damage to heat-sensitive substances, has lower costs, and provides low resistance and uniform heating under vacuum conditions.

[0004] While this device utilizes a triangular connecting plate to drive the drying chamber in a reciprocating oscillation, causing the food to tumble repeatedly within the chamber and thus achieving low-temperature drying, its integrated chamber structure limits the heat-exposed area of ​​the food. This results in uneven heat exchange, low drying efficiency, and a tendency for localized overheating or moisture residue due to material accumulation, affecting the quality and shelf life of the finished product. Furthermore, the integrated chamber structure makes cleaning and maintenance difficult and time-consuming, especially when loading and unloading materials. Therefore, those skilled in the art require a vacuum drying device for food production to address the problems described in the background section. Summary of the Invention

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figures 1-5As shown, this utility model provides a technical solution: a vacuum drying equipment for food production, including a base 1 for support, two first guide rails 2 fixedly connected to one side of the upper end of the base 1, a box 3 for providing a drying environment slidably connected to the upper end of the two first guide rails 2, a plurality of carrying components 4 for layering food are installed inside the box 3, the plurality of carrying components 4 are arranged in an upper and lower array, a swing component 5 for driving the box 3 to move back and forth is installed on one side of the upper end of the base 1, a vacuum component 6 for drawing the box 3 to a vacuum state is installed on one side of the upper end of the base 1, and a heating component 7 for drying is installed inside the box 3.

[0022] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, the loading component 4 includes a second guide rail 401. Two second guide rails 401 are provided and are symmetrically arranged. The two second guide rails 401 are respectively fixedly connected to the inner walls of both sides of the box 3. The upper outer sides of the two second guide rails 401 are slidably connected to a tray 402. The bottom of the inner wall of the tray 402 has multiple rows of ventilation holes 403. Two limiting components for preventing the tray 402 from moving are installed inside the tray 402. The two limiting components are symmetrically arranged.

[0023] Furthermore, a sealing door is hinged to one side of the box 3, which can cover the opening of the box 3 and keep the inside of the box 3 sealed. By placing food inside the tray 402 and then inserting the tray 402 into the corresponding second guide rail 401, the food can be placed in layers inside the box 3. Placing the food in layers can avoid uneven heat exchange caused by food accumulation, expand the heating area of ​​the food, ensure that each layer of food is heated evenly, and significantly improve drying efficiency.

[0024] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, the limiting component includes a sliding cavity 404 and a limiting groove 405. The sliding cavity 404 is opened inside the tray 402, and the limiting groove 405 is opened on the inner wall of one side of the box 3. Multiple springs 406 are fixedly connected to the inner wall of the sliding cavity 404, and a moving block 407 is slidably connected to the inner wall of the sliding cavity 404. The front ends of the multiple springs 406 are fixedly connected to one side of the moving block 407. A limiting rod 408 is fixedly connected to the side of the moving block 407 away from the springs 406. The limiting rod 408 passes through the tray 402, and the limiting rod 408 and the limiting groove 405 are engaged. A toggle opening 409 is opened on the inner wall of one side of the sliding cavity 404. The toggle opening 409 communicates with the outside and is connected to the outside. A toggle block 410 is slidably connected inside the toggle opening 409, and one end of the toggle block 410 is fixedly connected to one side of the moving block 407.

[0025] Furthermore, when placing the tray 402, the user squeezes the two actuating blocks 410, causing the two moving blocks 407 to move closer together. The spring 406 inside the sliding cavity 404 contracts, and the front ends of the limiting rods 408 on both sides of the tray 402 temporarily retract into the tray 402. When the tray 402 is fully pushed into the box 3, the front ends of the limiting rods 408 on both sides are respectively aligned with the two limiting grooves 405. At this time, the actuating blocks 410 are released, and the springs 406 return to their original position, allowing the front ends of the limiting rods 408 to slide into the limiting grooves 405. The limiting rods 408, in conjunction with the limiting grooves 405, can fix the tray 402, making it easy for the user to quickly fix and remove the tray 402, saving time and simplifying the process of placing and removing food. It also ensures the stability of the tray 402 within the box 3, preventing the tray 402 from shaking or tipping over during the drying process, effectively preventing material spillage, and ensuring that the food is layered and heated evenly, thus improving drying efficiency and equipment reliability.

[0026] As one implementation method in this embodiment, please refer to Figure 4 As shown, the swing assembly 5 includes a motor 501 and a first connecting rod 502. The motor 501 is fixedly installed on one side of the upper end of the base 1. The first connecting rod 502 is rotatably connected to the lower side wall of the housing 3 near the motor 501. The output end of the motor 501 is fixedly connected to a second connecting rod 503. One side of the second connecting rod 503 is hinged to the side wall of the first connecting rod 502.

[0027] Furthermore, during the drying process, the motor 501 starts working, the second connecting rod 503 rotates, and the second connecting rod 503 drives the first connecting rod 502 to swing. One end of the first connecting rod 502 swings back and forth on one side of the box 3, which in turn drives the box 3 to slide back and forth outside the first guide rail 2, so that the food in the tray 402 can be shaken, thereby continuously adjusting the position of the food in the tray 402, ensuring that the food is heated evenly, accelerating the evaporation of moisture on the surface of the food and preventing the food from sticking together, and further improving the drying efficiency and quality consistency.

[0028] As one implementation method in this embodiment, please refer to Figure 4 As shown, the air extraction assembly 6 includes a vacuum pump 601 and an air extraction pipe 602. The vacuum pump 601 is fixedly installed on one side of the upper end of the base 1. The air extraction pipe 602 passes through the housing 3, and the input end of the air extraction pipe 602 is connected to the inside of the housing 3. The air extraction end of the vacuum pump 601 is connected to a connecting hose 603, and the input end of the connecting hose 603 is connected to the output end of the air extraction pipe 602.

[0029] Furthermore, after the food placed in the tray 402 is placed into the box 3, the air inside the box 3 is continuously extracted by the vacuum pump 601 through the air extraction pipe 602 and the connecting hose 603 to form a low-pressure vacuum environment. By reducing the air pressure inside the box 3, the moisture evaporates quickly at a low temperature, avoiding the destruction of food nutrition and flavor by high temperature. This can significantly shorten the drying time, improve drying uniformity, and reduce energy consumption. At the same time, the vacuum environment inhibits oxidation and microbial growth, effectively maintaining the color, taste and shelf life of the food.

[0030] As one implementation method in this embodiment, please refer to Figures 4-5 As shown, the heating assembly 7 includes a heating chamber 701 and a temperature sensor 702. The heating chamber 701 is located inside the housing 3, and the temperature sensor 702 is installed on the outside of the housing 3. The detection end of the temperature sensor 702 is located inside the housing 3. Multiple heating rods 703 arranged in an array are installed inside the heating chamber 701.

[0031] Furthermore, the heating rods 703 arranged in an array within the heating chamber 701 uniformly heat the interior of the chamber 3, and the temperature sensor 702 monitors and adjusts the temperature inside the chamber in real time, efficiently evaporating food moisture under low-temperature conditions and avoiding damage to the nutritional components and flavor of the food by high temperatures.

[0032] Working principle: By placing food inside the tray 402 and then inserting the tray 402 into the corresponding second guide rails 401, the food can be layered inside the box 3. Layering the food avoids uneven heat exchange caused by food accumulation, increases the heating area of ​​the food, ensures uniform heating of each layer of food, and significantly improves drying efficiency. When placing the tray 402, the user squeezes the two actuating blocks 410, causing the two moving blocks 407 to move closer together. The spring 406 inside the sliding cavity 404 contracts, and the front ends of the limiting rods 408 on both sides of the tray 402 temporarily retract into the tray 402. When the tray 402 is fully pushed into the box 3... After entering the interior, the front ends of the limiting rods 408 on both sides are aligned with the two limiting grooves 405. When released, the spring 406 returns to its original position using the toggle block 410, allowing the front ends of the limiting rods 408 to slide into the limiting grooves 405. The limiting rods 408, in conjunction with the limiting grooves 405, can fix the tray 402, facilitating quick fixing and disassembly of the tray 402 by the user, saving time and simplifying the process of placing and removing food. It also ensures the stability of the tray 402 within the housing 3, preventing the tray 402 from shaking or tipping over during the drying process, effectively preventing material spillage, and ensuring that the food is evenly heated in layers, thus improving drying efficiency and equipment reliability.
