[0002] Fruit and vegetable-based gel materials have good flavor, bright colors, and rich nutritional value. They are widely used as 3D printing inks and can be used to customize various printed products with novel shapes and rich nutrition.

[0003] Fruit and vegetable-based gel materials are usually homogenized with fruit and vegetable juice or fruit and vegetable paste and a certain ratio of starch or colloid.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described 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, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0033] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0034] Figure 1 1 is a schematic diagram of a storage and printing work cabin for fruit and vegetable based gel materials based on a fresh-keeping database provided by an embodiment of the present invention. Figure 1 As shown, the device includes: a working cabin 110, an environmental sensing component 120, a control system 130, a plurality of functional modules 140 and a printing module 150;

[0035] The working cabin 110 includes multiple sealed doors and visual windows, which are convenient for equipment installation and timely observation and intervention of the printing process. Figure 2 As shown, Figure 21 is a schematic diagram of the appearance of a storage and printing work cabin for fruit and vegetable-based gel materials based on a fresh-keeping database provided by an embodiment of the present invention. Optionally, the work cabin body 110 can be composed of stainless steel, plywood and polyurethane, and the visualization window is made of hollow glass with a light strip embedded therein, so that the situation in the cabin can be observed without opening the cabin door, and a complete viewing angle is provided with bright lighting.

[0036] The environmental sensor component 120 is used to collect environmental data in the working cabin and send the environmental data to the control system; wherein the environmental sensor component 120 includes one or more of a temperature and humidity sensor, an oxygen concentration sensor, a carbon dioxide concentration sensor, an ethylene concentration sensor, and an ozone concentration sensor. In this embodiment, environmental data can be collected by the above sensors and sent to the control system to control the operation of the corresponding functional modules. The environmental data includes but is not limited to temperature, humidity, oxygen concentration, etc.

[0037] The control system 120 includes a central control unit and a detection unit corresponding to the functional module. The control system 130 is used to receive the environmental data. In each of the detection units, the environmental data is detected based on the preset judgment logic and the preservation parameters of the fruit and vegetable-based gel material, and a control request for the functional module corresponding to the detection unit is generated, and the control request is sent to the functional module 140 corresponding to the detection unit. Among them, the preservation parameters include but are not limited to temperature, humidity, gas conditioning parameters, etc., which are not limited here. The preset judgment logic is the logic for judging whether the functional module corresponding to the detection unit is started and operated. The judgment logic of the detection unit corresponding to different functional modules is different, which is set by those skilled in the art according to the needs, and is not limited here. It can be understood that the preset judgment logic is set based on the insurance parameter. For example, assuming that the suitable temperature of the fruit and vegetable gel material is 8°C, if the temperature in the working cabin is greater than 8°C, a refrigeration request is generated and sent to the refrigeration module.

[0038] It can be understood that the control requests generated by different detection units are different. For example, the detection unit corresponding to the refrigeration module can generate a refrigeration request, the detection unit corresponding to the gas conditioning module can generate a nitrogen production and oxygen reduction request or an ethylene removal request, the detection unit corresponding to the humidification module can generate a humidification request, and the detection unit corresponding to the ozone sterilization module can generate an ozone sterilization request, etc., and examples will not be given one by one here.

[0039] In some embodiments, optionally, the control system 120 is loaded with a fruit and vegetable based gel material preservation database, and the fruit and vegetable based gel material preservation database is used to store the preservation parameters of the fruit and vegetable based gel material.

[0040] In this embodiment, a single factor test was conducted by storing starch gel materials from different fruit and vegetable sources in a working cabin. The experimental process is as follows: Figure 3 As shown, the storage environment temperature conditions (1°C, 4°C, 8°C, 12°C, room temperature), humidity conditions (95%, 90%, 85%, no humidification), and oxygen concentration conditions (3%, 5%, 10%, 15%, normal oxygen) are adjusted in turn. The changes in pH, hardness, and color of the fruit and vegetable gel materials during storage, as well as the retention of moisture content, vitamin C content, and polyphenol content are used as the basis for judgment to determine the parameters of temperature, humidity, and oxygen concentration suitable for storage. Compared with the unregulated normal temperature and normal oxygen printing environment, the quality fidelity of the material can be improved by more than 20% after multi-environmental factor regulation. Some experimental results are shown in Table 1. The application of this database is convenient for users to refer to. Just select the storage fruit and vegetable base category on the operation screen to automatically load the appropriate environmental parameters. The printed products are temporarily stored in the working cabin and will not deteriorate in a short time, which is conducive to continuing subsequent packaging and other processes.

[0043] The functional module 140 includes an air conditioning module 141 , a refrigeration module 142 , a humidification module 143 , an ozone sterilization module 144 and an alarm module 145 .

[0044] The gas conditioning module 141 is connected to the working cabin 110 through a pipeline. The gas conditioning module includes a nitrogen generator and an ethylene removal unit, which are respectively used to respond to the control request and control the oxygen content and ethylene content in the working cabin. In this embodiment, when the detection unit corresponding to the gas conditioning module 141 detects that the oxygen content in the working cabin exceeds the set value, a nitrogen generation and oxygen reduction request is issued. In response to the nitrogen generation and oxygen reduction request, the nitrogen generator is turned on to reduce oxygen until the target set value is reached, and the nitrogen generator stops working. When the detection unit corresponding to the gas conditioning module 141 detects that the ethylene content in the working cabin exceeds the set value, an ethylene removal request is issued. In response to the ethylene removal request, the ethylene removal unit works regularly according to the program setting time. It should be noted that the oxygen concentration in the working cabin can be adjusted in the range of 3% to 21%, and the control accuracy is ±0.5%.

[0045] The refrigeration module 142 includes a compression condensing unit and an evaporation unit, which are used to control the temperature in the working cabin in response to the control request; wherein the compression condensing unit is arranged outside the working cabin, and the evaporation unit is arranged inside the working cabin; specifically, the compression condensing unit is composed of a compressor, an oil-gas separator, a condenser, a drying filter, a liquid indicator, a gas-liquid separator and pipelines, and the evaporation unit is composed of an evaporation coil, a cooling fan, a throttle valve and a solenoid valve. In this embodiment, when the detection unit corresponding to the refrigeration module 142 detects that the temperature collected in the working cabin is not within the target temperature range, a refrigeration request is issued, and in response to the refrigeration request, the refrigeration module 142 is started to operate for cooling. It should be noted that the temperature can be adjusted in the range of -3°C to 18°C, and the temperature control accuracy is ±0.5°C.

[0046] The humidification module 143 is arranged in the working cabin, and is used to control the humidity in the working cabin in response to the control request; specifically, the humidification module 143 is composed of a water tank, a liquid level gauge, a solenoid valve, a deflector, a high-frequency water mist oscillator and a water pump. In this embodiment, the humidification module has an automatic water replenishment function, and no manual water addition is required. The humidification module is internally provided with three water level monitorings: high, medium and low. When the detection unit corresponding to the humidification module 143 detects that the water level is lower than the low liquid level, a water replenishment request is issued, and the water replenishment solenoid valve is opened for automatic water replenishment; when the water level is detected to exceed the medium liquid level, a water replenishment stop request is issued, and the water replenishment solenoid valve is closed; when it is detected that the liquid level is too high due to a failure of the solenoid valve, a high water level alarm is issued. It should be noted that the humidity range is adjustable from 60% to 100%, and the control accuracy is ±5%.

[0047] The ozone sterilization module 144 is arranged in the working cabin, and is used to respond to the control request and perform ozone sterilization in the working cabin according to the pre-set ozone sterilization parameters; specifically, the ozone sterilization module 144 is composed of an ozone generator box, an ozone detector box, an ozone plate, a circuit and an electrochemical ozone sensor. In this embodiment, in response to the ozone sterilization request issued by the corresponding detection unit of the ozone sterilization module 144, ozone sterilization can be performed in the working cabin according to the pre-set ozone sterilization parameters. Among them, the ozone sterilization parameters include the start time, end time and sterilization duration of ozone sterilization.

[0048] The alarm module 145 is used to respond to the control request and send out an alarm signal. Specifically, the alarm module 145 is composed of a buzzer, an alarm indicator and a safety alarm system. In this embodiment, in order to ensure that abnormalities in the submodules of the equipment can be discovered in time, a safety alarm system is set on the electrical control box. Once a fault occurs, the system will send out an alarm signal and automatically stop the operation of the corresponding submodule. In addition to the equipment failure alarm, when the detection unit corresponding to the alarm module 145 detects that the oxygen concentration is not within the preset safety limit range, the working cabin door is locked by the solenoid valve and cannot be opened, and there will also be a door opening alarm prompt on the operation interface. Among them, the preset safety limit range is set by a technician in this field and is not limited here.

[0049] It is understood that in any case, the system will automatically shut down when the working cabin door is opened, which is controlled by the door limit switch.

[0050] The printing module 150 is arranged in the working cabin, and is used for 3D printing of fruit and vegetable based gel materials; specifically, the printing module 150 is composed of a printer, a dual nozzle robotic arm, an air pump and an air pressure controller, and the printing module 150 is connected to an external computer, and the printing module 150 is used to respond to the control operation of the external computer, adjust the operating parameters of the printing module, and control the printing process of the printing module based on the operating parameters. After printing is completed, the conveyor belt is automatically controlled to rotate, the product is transported forward, and the next product is printed.

[0051] Based on the above embodiment, optionally, the control system and the environmental sensing component and the multiple functional modules are connected via Ethernet or optical fiber. Through network transmission, the problems of large number of cable laying and complicated wiring harnesses, long signal transmission distance, low accuracy of collected data and poor electromagnetic compatibility caused by the previous integrated control method are greatly reduced.

[0052] The technical solution of this embodiment is that the storage and printing work cabin for fruit and vegetable-based gel materials based on the preservation database provided by the present invention integrates refrigeration, gas conditioning, ethylene removal, humidification, and ozone sterilization, which can provide a comprehensive storage and printing space for fruit and vegetable-based gel materials, improve the situation that the materials are easy to brown and corrupt, and at the same time, the device can integrate the preservation of materials, product printing and storage, and promote the continuous, industrialized and large-scale development of 3D printing. Compared with room temperature storage, after regulating multiple environmental factors and storing at the optimal temperature, humidity, and oxygen concentration for the same time, the retention rate of pigments, vitamin C, polyphenols, flavonoids and other components of fruit and vegetable materials can be improved, and the quality fidelity of the materials can be effectively improved.
