Description

Technical Field

[0001] This utility model relates to the field of vegetable production equipment technology, specifically to an energy-saving frostbitten vegetable machine. Background Technology

[0002] Vegetables, especially leafy greens, taste better after being exposed to frost. Frost-bitten vegetables need to be cooled down from 15 degrees Celsius. Vegetables grown under natural conditions can only produce better-tasting frost-bitten vegetables in the cold climate of the north, which limits their production area and increases transportation costs.

[0003] Chinese Patent Publication No. CN113207501A, published on August 6, 2021, discloses an invention entitled "An Organic Vegetable Production System." This application discloses an organic vegetable production system including a cabinet with a door made of transparent glass on the front. The cabinet includes a frame, with transparent glass installed on each surface of the frame. A rotating shaft is rotatably mounted inside the cabinet, connected to a geared motor via a transmission device. The geared motor is fixedly mounted inside the cabinet. Several planting units are fixedly mounted on the rotating shaft. Each planting unit includes a support and a main planting tray. The support is conical with its base facing upwards, and a convex reflective lens corresponding to its shape is provided on its outer surface. The support is fixedly mounted on the rotating shaft, and the main planting tray is fixedly mounted on the support. Although this organic vegetable production system can artificially grow organic vegetables indoors, it cannot cultivate frost-damaged vegetables, resulting in a poorer taste. Utility Model Content

[0004] The purpose of this invention is to solve the above problems and provide an energy-saving frost-damaged vegetable machine. By setting up a pre-cooling zone, several low-temperature zones and frost-damaged zones, it enables large-scale artificial cultivation of frost-damaged vegetables, reduces energy consumption, lowers costs, and improves the taste and quality of vegetables.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an energy-saving frost-damaged vegetable machine, comprising a refrigeration unit and a cabinet, wherein the cabinet is equipped with a vegetable channel, which consists of several low-temperature zones and frost-damaged zones connected in sequence; adjacent zones are separated by insulating partitions, which are movable; a conveying mechanism is provided at the bottom of the several low-temperature zones and frost-damaged zones. By setting up a pre-cooling zone, several low-temperature zones, and frost-damaged zones, the temperature from noon to night in northern regions is simulated. The vegetables pass through the pre-cooling zone, several low-temperature zones, and frost-damaged zones in sequence via the conveying mechanism, thus simulating frost treatment on the artificially modularly grown vegetables before harvesting, resulting in better taste.

[0006] Preferably, the vegetable aisle has an inlet insulated door at one end of the pre-cooling zone and an outlet insulated door at one end of the frost-prone zone. By installing insulated doors, heat exchange between the inside and outside of the cabinet can be reduced, thus improving energy efficiency.

[0007] Preferably, the inner wall of the cabinet is equipped with an insulation layer, and several slide rails are provided on the inner wall of the cabinet at the corresponding positions of the insulation partitions. The insulation partitions are slidably installed in the slide rails. The slide rails allow the insulation partitions to move freely, ensuring different temperatures in each temperature control zone while allowing vegetables to move within the vegetable aisle.

[0008] Preferably, the inlet and outlet insulated doors are located at the same end of the cabinet, the pre-cooling zone and several low-temperature zones are on one side of the cabinet, and the frost-prone zone is on the other side. This layout optimizes the flow path of vegetables, utilizes cabinet space more efficiently, and increases processing capacity.

[0009] Preferably, the conveying mechanism includes a longitudinal conveyor and a transverse conveyor. Longitudinal conveyors are installed at the bottom of the pre-cooling zone, several low-temperature zones, and the frost-affected zone, while transverse conveyors are installed at the bottom of the end low-temperature zone and the frost-affected zone. This conveying structure enables the movement of vegetables within the vegetable channel.

[0010] Preferably, transport racks can be placed on the upper surfaces of the longitudinal and transverse conveyors, and several vegetable planting trays are placed on the transport racks. Placing transport racks on the conveyors can increase the loading capacity of vegetables and improve processing efficiency. At the same time, the design of the transport racks can protect the vegetables from damage during transportation and maintain their integrity.

[0011] Preferably, the temperature of the pre-cooling zone is 10-15 degrees Celsius, the temperature of the frost-affected zone is -3 to -5 degrees Celsius, and the temperature of several low-temperature zones decreases sequentially. Ultraviolet lamps are installed on the inner walls of the pre-cooling zone and an adjacent low-temperature zone. Precise temperature control can simulate the frost process under natural conditions, improving the taste and nutritional value of vegetables. The ultraviolet lamps can also disinfect the vegetables, improving food safety.

[0012] Preferably, the top of the pre-cooling zone, several low-temperature zones, and the frost-covering zone are each equipped with a cold air nozzle, which is connected to the refrigeration equipment via a cold air pipe. The cold air nozzle configuration allows for precise temperature control of each zone, ensuring the frost-covering effect.

[0013] Preferably, the longitudinal conveyor has a notch, the transverse conveyor is installed inside the notch, and the bottom of the transverse conveyor is equipped with a lifting mechanism.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] As people's living standards improve, their demands for the taste and nutritional value of food are also increasing. Vegetables, as an indispensable part of daily diet, directly impact consumers' health and quality of life through their taste and nutritional value. Traditional vegetable cultivation methods are often limited by climate conditions, especially in northern regions where low temperatures and frost can enhance the taste and nutritional value of vegetables. However, natural frost treatment is not only limited by region and season but also inefficient, making it difficult to meet the needs of large-scale production. Therefore, this invention proposes an energy-saving frost-treated vegetable machine, designed to simulate the frost process in a natural environment to treat artificially modularly cultivated vegetables, thereby improving their taste and nutritional value.

[0027] like Figure 1 and Figure 2 As shown, an energy-saving frost-treated vegetable machine consists of a cabinet 1. Cabinet 1 is made of robust and durable materials to ensure stability during prolonged operation. Inside cabinet 1 is a vegetable channel, the core component for simulating frost treatment of vegetables. This channel comprises a pre-cooling zone 3, several low-temperature zones 5, and a frost-treated zone 4, connected sequentially. These zones together form a U-shaped structure, allowing the vegetables 8 to flow smoothly within the channel while receiving temperature treatment at different stages. The pre-cooling zone 3 and the several low-temperature zones 5 are located on one side of cabinet 1, while the frost-treated zone 4 is located on the other side. This layout not only optimizes the space utilization within cabinet 1 but also makes the flow path of the vegetables 8 more rational, improving processing efficiency. The pre-cooling zone 3 and the frost-affected zone 4 are both located at one end inside the cabinet 1. These zones are isolated from each other by movable insulation partitions 2. The insulation partitions 2 also isolate the pre-cooling zone 3 from adjacent low-temperature zones 5, from several low-temperature zones 5, and from the end low-temperature zone 5 to the frost-affected zone 4, ensuring precise temperature control in each zone. The movable insulation partitions 2 allow the vegetables 8 to move between different zones while maintaining the temperature of each temperature control zone. Conveying mechanisms are installed at the bottom of the pre-cooling zone 3, several low-temperature zones 5, and the frost-affected zone 4. These conveying mechanisms consist of longitudinal conveyors 15 and transverse conveyors 16. The pre-cooling zone 3 and several low-temperature zones 5 each have a longitudinal conveyor 15 at their bottom, while the end low-temperature zone 5 and the frost-affected zone 4 have a transverse conveyor 16 at their bottom. This composite conveying mechanism design allows the vegetables 8 to move flexibly within the vegetable flow channel, sequentially passing through the pre-cooling zone 3, several low-temperature zones 5, and the frost-affected zone 4, completing the simulated frost treatment.

[0028] like Figure 2 and Figure 3As shown, the design of the vegetable aisle fully considers the flow path of vegetables 8 and space utilization to achieve high-efficiency processing capacity. An inlet insulated door 10 is provided at one end of the pre-cooling zone 3 of the vegetable aisle, and an outlet insulated door 11 is provided at one end of the frost-affected zone 4. The inlet insulated door 10 and the outlet insulated door 11 are located on the same surface of the cabinet 1. The design of these insulated doors can effectively reduce heat exchange between the inside and outside of the cabinet 1, improving energy efficiency. The passageway contains a pre-cooling zone 3, several low-temperature zones 5, and a frost-affected zone 4 arranged sequentially. In this embodiment, two low-temperature zones 5 are selected: Low-temperature zone one and Low-temperature zone two. The temperature of the pre-cooling zone 3 is controlled at 10-15 degrees Celsius, and the temperature of the frost-affected zone 4 is controlled at -3 to -5 degrees Celsius. The temperatures of the several low-temperature zones 5 decrease sequentially. In this embodiment, the temperature of the pre-cooling zone 3 is preferably 15 degrees Celsius to simulate the midday temperature in northern regions, the temperature of low-temperature zone one is preferably 10 degrees Celsius to simulate the afternoon temperature in northern regions, the temperature of low-temperature zone two is preferably 5 degrees Celsius to simulate the evening temperature in northern regions, and the temperature of frost-affected zone 4 is preferably -5 degrees Celsius to simulate the nighttime temperature in northern regions. Vegetables 8 are placed on the transport rack 6 and pass through the pre-cooling zone 3, low-temperature zone one, low-temperature zone two, and frost-affected zone 4 sequentially via the horizontal conveyor 16 and the vertical conveyor 15. After the vegetables 8 are pushed into the pre-cooling zone 3, the inlet insulation door 10 is closed to prevent cold air from escaping. In this embodiment, it is preferred to refrigerate for one hour to gradually lower the temperature to 15 degrees Celsius, preparing for subsequent cooling. One hour later, the insulation partition 2 between the pre-cooling zone 3 and the adjacent low-temperature zone 1 is opened, and the vegetables 8 enter the low-temperature zone 1 through the longitudinal conveyor 15 at the bottom. Because the insulation partition 2 is open, they slide to the frost zone 4 via the slide rail. At this time, the temperature of the pre-cooling zone 3 and the low-temperature zone 1 is between 10 degrees Celsius and 15 degrees Celsius. The insulation partition 2 between the pre-cooling zone 3 and the adjacent low-temperature zone 1 is closed, and the temperature in the low-temperature zone 1 is controlled by the control system to gradually lower the temperature in the low-temperature zone 1 to 10 degrees Celsius. In this embodiment, it is preferred to refrigerate for one hour and then repeatedly open the inlet insulation door 10 to put in new vegetables 8 into the low-temperature zone 1. Since the temperature in the low-temperature zone 1 is below 15 degrees Celsius at this time, putting in new vegetables 8 will save some energy. One hour later, the insulation partition 2 between low-temperature zone one and the adjacent low-temperature zone two is opened, and the vegetables 8 slide to the frost-affected zone 4 via the slide rail. The vegetables 8 enter the low-temperature zone two via the longitudinal conveyor 15 at the bottom. Because the insulation partition 2 is open, the temperature of low-temperature zone one and low-temperature zone two is between 5 degrees Celsius and 10 degrees Celsius. The insulation partition 2 between low-temperature zone one and the adjacent low-temperature zone two is then closed, and the temperature in low-temperature zone two is controlled by the control system to gradually lower the temperature in low-temperature zone two to 5 degrees Celsius. In this embodiment, it is preferred to refrigerate for one hour.Because the frost-affected zone 4 contains three transport racks 6, and the temperature requirement is consistent, the movement of the two insulation partitions 2 mentioned above has no effect on it. After one hour, the insulation partition 2 between the low-temperature zone 2 and the frost-affected zone 4 is opened, and the vegetables slide between the two refrigeration devices 20 via a slide rail. The vegetables 8 enter the frost-affected zone 4 through the horizontal conveyor 16 and lifting mechanism 19 at the bottom. Because the insulation partition 2 is open, the temperature of the low-temperature zone 2 and the frost-affected zone 4 is between 5 degrees Celsius and 10 degrees Celsius. The insulation partition 2 between the low-temperature zone 2 and the adjacent frost-affected zone 4 is then closed. The temperature in the frost-affected zone 4 is controlled by the control system, so that the temperature in the frost-affected zone 4 gradually decreases to -5 degrees Celsius. In this embodiment, refrigeration is preferably carried out for three hours. This precise temperature control can simulate the frost process under natural conditions, improving the taste and nutritional value of the vegetables 8. In addition, ultraviolet lamps 14 are installed on the inner walls of the pre-cooling zone 3 and the adjacent low-temperature zone 1, which are used to disinfect the vegetables 8 and improve food safety.

[0029] like Figure 1 and Figure 2 As shown, to ensure independent temperature control in each temperature-controlled zone, the inner wall of cabinet 1 is equipped with an insulation layer 9. The frost-affected zone 4, pre-cooling zone 3, and low-temperature zone 1 are also equipped with insulation layers 9. Several sliding rails are provided at corresponding positions on the insulation partitions 2 of the inner wall of cabinet 1, allowing the insulation partitions 2 to slide within them. The insulation layer 9 also has partition grooves at corresponding positions, allowing the insulation partitions 2 to be placed within these grooves. This design not only improves the insulation performance of cabinet 1 but also allows the insulation partitions 2 to move freely as needed to adapt to the processing requirements of different vegetables 8.

[0030] like Figure 4 , Figure 5 and Figure 6 As shown, the conveying mechanism includes two longitudinal conveyors 15 and a transverse conveyor 16. One longitudinal conveyor 15 is located at the bottom of the pre-cooling zone 3, the first low-temperature zone, and the second low-temperature zone. The other longitudinal conveyor 15 is located at the bottom of the frost-affected zone 4. The transverse conveyor 16 is located at the bottom of the end of the second low-temperature zone and the frost-affected zone 4. The longitudinal conveyor 15 includes two parallel conveyor belts 17. The transverse conveyor 16 and the longitudinal conveyor 15 are connected at one end of the second low-temperature zone. The conveyor belt 17 of the transverse conveyor 16 has a notch 18. The longitudinal conveyor 15 is located in the notch 18. The bottom of the transverse conveyor 16 is provided with a lifting mechanism 19. In this embodiment, the lifting mechanism 19 is preferably a hydraulic cylinder. This composite conveying mechanism design allows the vegetables 8 to move flexibly in the vegetable channel, improving processing efficiency and flexibility.

[0031] like Figure 1As shown, a transport rack 6 can be placed on the upper surface of the longitudinal conveyor 15 and the transverse conveyor 16. The transport rack 6 includes a base 12 and several shelves 13 placed on the base 12. Vegetable planting trays 7 are placed on the shelves 13. The height of the vegetables 8 and the vegetable planting trays 7 must not exceed the distance between the shelves 13, and a certain gap must be maintained to ensure the frost protection effect of the vegetables 8. The height of the transport rack 6 is less than the height of each temperature control zone. This design can increase the loading capacity of vegetables 8 and improve processing efficiency. At the same time, the design of the transport rack 6 can protect the vegetables 8 from damage during transportation and maintain the integrity of the vegetables 8.

[0032] like Figure 1 As shown, the top of the pre-cooling zone 3, several low-temperature zones 5, and the frost zone 4 are respectively equipped with cold air nozzles 22, which are connected to the refrigeration equipment 20 through cold air pipes 21. In this embodiment, there are two refrigeration equipment 20, which are respectively set on one side of the insulation zone 2 and the frost zone 4. The temperature of each temperature control zone is precisely controlled by the control system. Each temperature control zone is equipped with a thermometer for frequency conversion temperature adjustment. This design can accurately control the temperature of each area to ensure the frost effect.

[0033] Work process.

[0034] 1. Vegetable loading.

[0035] like Figure 7 As shown, the vegetable planting tray 7 is placed on the transport rack 6, the inlet insulation door 10 is opened, and then the transport rack 6 is placed on the longitudinal conveyor 15 of the pre-cooling zone 3.

[0036] 2. Pre-cooling treatment.

[0037] After vegetables 8 enter the pre-cooling zone 3, the inlet insulation door 10 is closed. In the pre-cooling zone 3 and an adjacent low-temperature zone, ultraviolet lamps 14 disinfect vegetables 8. The temperature of the pre-cooling zone 3 is gradually reduced to 15 degrees Celsius by the control system of the refrigeration equipment 20, simulating the midday temperature in northern regions, and refrigeration is carried out for one hour.

[0038] 3. Low-temperature treatment.

[0039] like Figure 8 As shown, after one hour of pre-cooling in the pre-cooling zone 3, the insulation partition 2 between the pre-cooling zone 3 and the adjacent low-temperature zone 5 is opened. After the vegetables 8 enter the low-temperature zone 1 via the longitudinal conveyor, the insulation partition 2 is closed. The temperature of the low-temperature zone 1 is gradually reduced to 10 degrees Celsius by the control system of the refrigeration equipment 20, simulating the afternoon temperature in the northern region, and refrigeration is carried out for one hour.

[0040] After one hour of pre-cooling in low-temperature zone one, the insulation partition 2 between low-temperature zone one and low-temperature zone two is opened. After the vegetables 8 enter low-temperature zone two through the longitudinal conveyor, the insulation partition 2 is closed. The temperature of low-temperature zone two is gradually reduced to 5 degrees Celsius by the control system of refrigeration equipment 20, simulating the temperature of northern regions in the evening, and refrigeration is carried out for one hour.

[0041] 4. Frostbite treatment.

[0042] like Figure 9 As shown, after one hour of cooling in the low-temperature zone 2, the vegetable transport rack 6 enters the frost zone 4 via the horizontal transport machine and the lifting mechanism 19. The temperature in this zone is controlled between -3 and -5 degrees Celsius to simulate the frost environment of northern nighttime temperatures, and the cooling lasts for three hours.

[0043] 5. Vegetable exports.

[0044] After undergoing a complete simulated frost treatment, vegetables 8 leave the energy-saving frost-beaten vegetable machine via longitudinal conveyor 15 and outlet insulated door 11.

[0045] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
