Furthermore, the technical features involved in the different embodiments of this application described below may be combined with each other as long as they do not conflict with each other.

[0024] Firstly, please refer to Figure 1 and Figure 2 This application provides a storage system, which includes a membrane component 001 and an environmental control component. The membrane component 001 includes a ground membrane 102 and a top membrane 101, which are detachably and sealed together, forming a storage space for accommodating stored items 200. The environmental control component includes an air conditioning unit 007, a controlled atmosphere unit 009, and a ventilation unit 008, all of which are connected to the storage space. The air conditioning unit 007 controls the temperature within the storage space, the controlled atmosphere unit 009 controls the concentration of inert gas within the storage space, and the ventilation unit 008 controls the uniformity of the gas within the storage space.

[0025] Please refer to Figure 3 The edges of the mulch film 102 and the top film 101 can be connected by an airtight zipper to achieve a detachable and sealed connection, enhancing the airtightness of the storage space. The stored items 200 can be grains, cash crops, agricultural by-products, medicinal herbs, etc.

[0026] The membrane component 001 encloses and forms a storage space with good sealing performance, effectively preventing the intrusion of animals, such as rodents and pests. This eliminates the need for chemical fumigation to kill insects or poison other animals, improving the protective capabilities and environmental friendliness of the storage system. It also eliminates the need for traditional physical rodent-proofing devices such as metal mesh, reducing rodent-proofing costs.

[0027] Due to the excellent sealing of the storage space, its moisture-proof and damp-proof performance is enhanced, improving the proactive control of mold growth. The air conditioning unit 007 facilitates the regulation of temperature and humidity within the storage space, mitigating the problem of condensation, heat generation, and mold growth in the stored item 200 due to the influence of external hot and humid air. It facilitates the application of physical storage technologies such as controlled atmosphere storage, lowering the barrier to entry for green storage technologies. For example, the controlled atmosphere unit 009 can regulate the concentration of inert gases within the storage space, reducing oxygen concentration and improving the storage effect of the stored item 200. The high barrier properties of the membrane component 001 physically isolate moisture and most oxygen, and combined with the low-oxygen environment maintained by the controlled atmosphere unit 009 using inert gases such as nitrogen, significantly improve the problem of mold growth in the stored item 200.

[0028] The temperature and inert gas concentration within the containment space can be regulated by the air conditioning unit 007 and the controlled atmosphere unit 009. It can also be used to kill pests and rodents without the need for chemical agents, thus improving environmental friendliness.

[0029] The membrane module 001 features a detachable connection between the ground membrane 102 and the roof membrane 101. It is understood that the ground membrane 102 and the roof membrane 101 are flexible, foldable, and lightweight, enabling the storage system to be quickly deployed, disassembled, and moved, thus improving flexibility. The flexible membrane module 001 is lightweight and easy to fold, and when paired with installation-free air conditioning units 007, controlled atmosphere units 009, and ventilation units 008, it significantly reduces the difficulty and cost of transportation, installation, and disassembly, making it suitable for various storage scenarios.

[0030] For the aforementioned air conditioning unit 007, an integrated multi-functional unit can be adopted, such as one equipped with cooling, dehumidification, and negative pressure functions. Air conditioning unit 007 can also be equipped with long-lasting, slow-release solid alkali granules for purifying circulating gas; a low-leakage, full-return air design can be adopted to reduce cooling loss and energy consumption.

[0031] For the aforementioned controlled atmosphere unit 009, the inert gas can be nitrogen, carbon dioxide, or other inert gases. Taking nitrogen as an example, if a membrane separation nitrogen generator is used, a high concentration of nitrogen is introduced into the containment space through pipelines, creating a low-oxygen environment within the containment space. For example, if the target nitrogen concentration is greater than 98%, the oxygen concentration will be less than 2%. The membrane module or controlled atmosphere unit 009 may be equipped with a breather valve or a safety pressure relief valve to mitigate the problem of damage to the membrane module 001 caused by temperature changes or overpressure or negative pressure during the filling process.

[0032] For the aforementioned ventilation unit 008, a small, low-volume circulating fan can be used. The circulating fan is used to promote uniform distribution of temperature, humidity, and gas within the storage space and the contents 200, and to improve the problem of localized condensation.

[0033] In some embodiments, please refer to Figure 1 and Figure 2 The storage system also includes tension straps 002, which are located on the outside of the top membrane 101, with both ends of the tension straps 002 connected to the ground on both sides of the top membrane 101. This restricts the shape of the membrane assembly 001, improving the problem of excessive expansion of the membrane assembly 001 after inflation, which leads to excessive space occupation and easy damage. Optionally, the membrane assembly 001 expands into a long strip shape, with multiple tension straps 002 arranged along the length of the membrane assembly 001. Optionally, the top membrane 101 is provided with waist buckles to define the position of the tension straps 002. Optionally, anchors 015 are provided on the ground, and the tension straps 002 are connected to the anchors 015. Optionally, the tension straps 002 include high-strength fiber braided strips with high tensile strength.

[0034] It should be noted that, in the embodiments of this application, the inner side of the membrane assembly 001 refers to the side of the membrane assembly 001 facing the center of the accommodating space, and the outer side of the membrane assembly 001 refers to the side of the membrane assembly 001 away from the accommodating space.

[0035] In some embodiments, please refer to Figure 1 The membrane assembly 001 also includes a flexible curtain door 003. The top membrane 101 has an opening, and the flexible curtain door 003 is used to open or seal the opening, thereby facilitating staff access to and from the accommodating space. The edges of the flexible curtain door 003 and the top membrane 101 can be connected by an airtight zipper to achieve a detachable and sealed connection.

[0036] In some embodiments, please refer to Figure 1 The top membrane 101 is provided with an observation window 004. The observation window 004 can be made of a transparent membrane material with high light transmittance and is welded to the top membrane 101 by high-frequency heat sealing, or it can be bonded with adhesive. Optionally, there are multiple observation windows 004, which are arranged at intervals along the length of the membrane material assembly 001.

[0037] In some embodiments, please refer to Figure 1 The top membrane 101 is equipped with a wind rope fixing ring 005. The wind rope fixing ring 005 can be connected to the ground via wind ropes, for example, to the ground anchor 015, to enhance wind resistance.

[0038] In some embodiments, please refer to Figure 3 The membrane material assembly 001 includes a sealing structure 006, which includes a curtain body and a curtain fixing piece. One of the curtain body and the curtain fixing piece is sealed to the top membrane 101, and the other is sealed to the ground membrane 102. The curtain body and the curtain fixing piece are detachably sealed to form a sealing cavity on the outside or inside of the connection between the ground membrane 102 and the top membrane 101. For example, the curtain body located outside the connection between the mulch film 102 and the roof film 101 is the outer curtain body 1021, and the curtain fixing piece is the outer curtain fixing piece 1012. The outer curtain body 1021 and the outer curtain fixing piece 1012 enclose a sealed cavity outside the connection between the mulch film 102 and the roof film 101. Alternatively, the curtain body located inside the connection between the mulch film 102 and the roof film 101 is the inner curtain body 1011, and the curtain fixing piece is the inner curtain fixing piece 1022. The inner and outer curtain bodies 1021 and the inner curtain fixing piece 1022 enclose a sealed cavity inside the connection between the mulch film 102 and the roof film 101. The curtain body and the curtain fixing piece can be connected to the roof film 101 and the mulch film 102 by high-frequency heat welding or bonding for a sealed connection. The curtain body and the curtain fixing piece can be connected by Velcro, airtight zippers, or self-sealing strips with concave and convex ribs. A double-layer seal is achieved by forming a sealed cavity on the outside or inside of the connection between the mulch film 102 and the top film 101, thereby enhancing the airtightness of the accommodating space. Optionally, the outer curtain body 1021 is connected to the mulch film 102, and the outer curtain fixing piece 1012 is connected to the top film 101. Optionally, the inner curtain body 1011 is connected to the top film 101, and the inner curtain fixing piece 1022 is connected to the bottom film.

[0039] In some embodiments, please refer to Figure 3 The membrane assembly 001 includes two sealing structures 006, which are respectively located on the inner and outer sides of the connection between the ground membrane 102 and the top membrane 101, so as to form a sealed cavity on both the outer and inner sides of the connection between the ground membrane 102 and the top membrane 101. This achieves a triple seal, further enhancing the sealing performance of the accommodating space.

[0040] In some embodiments, the aforementioned sealing structure 006 is also provided between the flexible curtain door 003 and the top membrane 101, for example, on the inner or outer side of the connection between the flexible curtain door 003 and the top membrane 101, to enhance the sealing of the accommodating space. Optionally, the sealing structure 006 is provided on both the inner and outer sides of the connection between the flexible curtain door 003 and the top membrane 101.

[0041] In some embodiments, please refer to Figure 4 At least one of the mulch film 102 and the roof film 101 includes a composite membrane layer, which includes an intermediate layer 103 and an outer layer 104. The intermediate layer 103 forms a sealed accommodating space, and the outer layer 104 is located on the side of the intermediate layer 103 opposite to the accommodating space. The outer layer 104 has a repellent material. For example, the mulch film 102 and the roof film 101 are cut from the composite membrane layer. The intermediate layer 103 may be made of a material with extremely low permeability to oxygen and water vapor, such as EVOH (ethylene-vinyl alcohol copolymer), aluminized film, aluminum foil, or high-performance barrier nylon, to improve the sealing and moisture-proof properties of the accommodating space. The outer layer 104 may be made of a high-strength, weather-resistant polymer, such as modified PVC (polyvinyl chloride), TPU (thermoplastic polyurethane elastomer), or high-strength polyester. The outer layer 104 contains repellent substances added to or incorporated into its surface or near-surface area. These repellent substances include, but are not limited to, capsaicin compounds, menthol, camphor, or other food-grade repellents that produce strong olfactory and gustatory discomfort in rodents but are safe for humans and environmentally friendly. The repellent substances can be encapsulated in microcapsules and mixed into the outer layer 104, mixed in liquid form with the raw materials of the outer layer 104, or fixed to the surface of the outer layer 104 using molecular grafting technology.

[0042] When rodents attempt to gnaw on the composite membrane layer, their mouths and noses directly contact the repellent substance on the outer layer 104, producing a strong pungent, cooling, or other uncomfortable sensation, thus voluntarily abandoning the gnawing behavior. This forms a proactive repellent protection based on biological behavior, achieving active rodent control rather than simply relying on the material's physical puncture resistance. This improves the problem of rodents repeatedly and tentatively gnawing on the composite membrane layer, protecting the integrity of the membrane component 001. Furthermore, the repellent substance is located on the outer layer 104, not in contact with the stored item 200, making it safe and environmentally friendly.

[0043] The outer 104 layer contains repellent material, and the low-temperature, low-oxygen environment within the containment space forms a dual active protection system, enhancing the effectiveness against insects and rodents.

[0044] In some embodiments, please refer to Figure 4 The composite membrane layer also includes an inner layer 105, which is located on the side of the intermediate layer 103 facing the accommodating space. The inner layer 105 is made of food-grade material. The inner layer 105 can be made of a food-grade, odorless and tasteless polymer that meets food-grade safety standards, such as PE (polyethylene) or PP (polypropylene), to isolate the intermediate layer 103 and the outer layer 104 from the item to be stored 200, thereby improving the safety of the item to be stored 200.

[0045] In one embodiment, the flexible curtain door 003 includes a composite film layer. For example, the flexible curtain door 003 is cut from a composite film layer.

[0046] In one embodiment, the water vapor transmission rate (WVTR) of the composite membrane is less than 3 g / (m²). 2 *24h) (Environmental conditions: 38 degrees Celsius, 90% humidity), Oxygen Transmission Rate (OTR) less than 1 cm. 3 / (m 2 *24h*0.1MPa) (Environmental conditions: 23 degrees Celsius and 0% humidity) gives membrane component 001 excellent moisture-proof and oxygen-barrier capabilities and airtightness.

[0047] In some embodiments, the composite film layer is a co-extruded, laminated, or coated composite structure. For example, the outer layer 104 and the inner layer 105 are coated layers, respectively applied to the two sides of the middle layer; or, the outer layer 104, the middle layer 103, and the inner layer 105 are all thin films, joined together by extrusion; or, during the production of the composite film layer, the outlets of the outer layer 104, the middle layer 103, and the inner layer 105 are close to each other, and the outer layer 104, the middle layer 103, and the inner layer 105 are all in a molten state and in contact when they are extruded from the outlets, so that they bond together to form a composite film layer after cooling.

[0048] In some embodiments, please refer to Figure 5The storage system also includes an auxiliary support assembly 014, which includes an inflatable frame. The inflatable frame supports the top membrane 101 after inflation and moves the top membrane 101 above the item to be stored 200. Exemplarily, the inflatable frame includes a U-shaped crossbeam after inflation, which can be an air rib. After deflation, the inflatable frame flattens. The top membrane 101 is placed on top of the inflatable frame, and the frame expands the top membrane 101 during inflation, causing it to arch. Moving the inflatable frame then moves the top membrane 101 above the item to be stored 200. The inflatable frame assists in supporting the formation of the top membrane 101, improving friction between the top membrane 101 and the item to be stored 200. After the membrane assembly 001 is inflated and formed, the inflatable frame can be deflated and removed. The auxiliary support assembly 014 can be used by multiple membrane assemblies 001. Optionally, the bottom of the inflatable frame is provided with a hanging ring 1401 for fixing the top membrane 101, thereby improving the problem of the top membrane 101 slipping off during the inflation of the inflatable frame. In some other embodiments, the auxiliary support assembly 014 includes a metal frame that can be quickly deployed and supported to arch the top membrane 101.

[0049] In some embodiments, please refer to Figure 6 The storage system also includes an insulation component, which comprises an insulation layer 012 and an insulation cover 010. The insulation layer 012 is disposed between the ground film 102 and the ground, and the insulation cover 010 and the insulation layer 012 enclose an insulation space. The membrane component 001 is disposed within the insulation space. By setting up the insulation component, the insulation effect of the storage space is enhanced. The insulation cover 010 can be made of materials with low thermal conductivity, such as chemical fiber quilts, rubber and plastic cotton, aluminum-coated XPE (chemically cross-linked polyethylene foam), or bubble aluminum film. The insulation layer 012 can be made of aluminum-coated XPE, or it can be made of load-bearing materials with good modified atmosphere insulation performance, such as rock wool board, polyurethane board, and extruded board. The insulation layer 012 and the insulation cover 010 do not need to be connected; for example, the edge of the insulation cover 010 can be pressed against the insulation layer 012 by gravity; or they can be simply connected, for example, by strapping.

[0050] In some embodiments, please refer to Figure 6 The storage system further includes an insulation component, which includes a floor 011 positioned between the stored item 200 and the ground film 102. The floor 011 supports the stored item 200, mitigating the problem of scratching the ground film 102 during transport, and can also elevate the stored item 200, reducing the risk of moisture absorption. The floor 011 can be made of non-slip, wear-resistant, and environmentally friendly materials, such as high-strength plastics, specifically PVC, TPU, and EVA (ethylene-vinyl acetate copolymer or resin).

[0051] In some embodiments, please refer to Figure 6 The storage system also includes a waterproof layer 013, which is disposed between the ground and the insulation layer 012. The waterproof layer 013 can be a cement layer or a rubber layer laid on the ground, making the ground structure more stable, less prone to mud formation, and helping to keep the environment of the membrane component 001 clean and tidy. The waterproof layer 013 can also have thermal insulation properties, reducing heat exchange between the ground and the membrane component 001, for example, by using foamed concrete to lay the cement layer.

[0052] In some embodiments, please refer to Figure 7 The storage system also includes a control component 016, which includes a control center 0161, sensors 0162, and a communication module 0163. Sensors 0162 are communicatively connected to the control center 0161, and the communication module 0163 connects the control center 0161 to a cloud platform or user terminal. Sensors 0162 may include sensors for temperature, humidity, oxygen concentration, carbon dioxide concentration, and pressure. The control center 0161 acquires data from the sensors 0162. Since the control center 0161 is connected to the cloud platform or user terminal, it can monitor the relevant information of the stored item 200 in real time through the cloud platform or user terminal. The communication module 0163 can be a Wi-Fi or 5G module. The cloud platform can be a monitoring website, a central control center 0161, etc.; the user terminal can be a smartphone, personal computer, tablet, etc. For example, please refer to [link to example]. Figure 2 The containment space is equipped with a temperature and humidity sensor 903, an air pressure sensor 904, and an oxygen concentration sensor 905.

[0053] It enables airtightness monitoring and alarm: the air pressure sensor 904 periodically and automatically monitors the air pressure in the containment space. When the air pressure drops beyond the expected level, it is determined that the containment space has poor sealing, and the control component 016 can issue a warning to the cloud platform and user terminal. Optionally, the control component 016 is a "Boku Cloud Control Platform".

[0054] In some embodiments, please refer to Figure 7 The control component 016 also includes a valve 0164, which is communicatively connected to the control center 0161. At least one valve 0164 is used to control the opening degree between the controlled atmosphere unit 009 and the accommodating space, and at least one valve 0164 is used to control the opening degree between the ventilation unit 008 and the accommodating space. For example, please refer to... Figure 2 A first air volume control valve 801 is installed between the ventilation unit 008 and the accommodating space; a controlled atmosphere unit 009 is connected to the accommodating space through an air duct 902, and a second air volume control valve 901 is installed between the controlled atmosphere unit 009 and the air duct 902. This controls the exhaust volume of the ventilation unit 008 and the controlled atmosphere unit 009.

[0055] In some embodiments, the control center 0161 is communicatively connected to the air conditioning unit 007, the controlled atmosphere unit 009, and the ventilation unit 008. The control center 0161 is used to control the air conditioning unit 007, the controlled atmosphere unit 009, and the ventilation unit 008. The control center 0161 can control the start / stop and operating modes of the air conditioning unit 007, the controlled atmosphere unit 009, and the ventilation unit 008.

[0056] Intelligent atmosphere control is achieved: real-time monitoring of oxygen concentration in the containment space. When the oxygen concentration is higher than the preset oxygen concentration (such as 3% or 2.5%), the atmosphere control unit 009 is automatically started to supplement inert gas and maintain an inert gas environment for a long time.

[0057] It enables comprehensive monitoring of grain conditions: by comprehensively analyzing temperature, humidity, and gas concentration data, it can provide early warnings of abnormal heating risks. For example, if some temperature and humidity sensors (903) detect a temperature greater than 100 degrees Celsius and a high oxygen concentration, they will determine that there is a risk of combustion and manual intervention is required.

[0058] It enables remote panoramic management and control: temperature and humidity data, gas concentration data, the operating status of air conditioning unit 007, controlled atmosphere unit 009, and air exchanger unit 008, and the opening degree of the first air volume control valve 801 and the second air volume control valve 901 can all be monitored and controlled in real time. Furthermore, it can automatically generate a full-cycle digital archive based on the monitored data, facilitating the analysis of the storage process.

[0059] By intelligently adjusting the controlled atmosphere environment through the control component 016, the storage status can be made controllable, significantly reducing the management intensity and the requirements for management expertise.

[0060] Secondly, embodiments of this application provide a storage method, which is applied to a storage system, and the method includes: S1: Set up a waterproof layer 013 in the target area, and then lay an insulation layer 012, a ground membrane 102 and a floor 011 on top of the waterproof layer 013.

[0061] The target area can be inside a building, such as a warehouse, or outdoors. The waterproof layer 013 can be a cement or rubber layer laid on the ground, making the ground structure more stable. A cement layer made of foamed concrete can be used, which has thermal insulation properties and reduces heat exchange between the ground and the membrane component 001. After the waterproof layer 013 is laid, the ground membrane 102 and the floor 011 are laid in sequence. The floor 011 can be a modular floor.

[0062] S2: Place the item to be stored, 200, on floor 011.

[0063] The item to be stored 200 is moved onto floor 011 using tools such as a forklift. The dimensions of the stacked item 200 must be smaller than the dimensions of the space occupied by the auxiliary support assembly 014.

[0064] S3: Place the auxiliary support component 014 on the ground, lay the top membrane 101 on top of the auxiliary support component 014, and let the auxiliary support component 014 expand to support the top membrane 101.

[0065] First, lay the inflatable frame of the auxiliary support component 014 flat on the ground, such as on the horizontal side of the floor 011. Then, lay the top membrane 101 on top of the inflatable frame. The hanging ring 1401 at the bottom of the inflatable frame is connected to the top membrane 101. After the inflatable frame is inflated, it becomes an arch shape, thereby supporting the top membrane 101.

[0066] S4: Move the auxiliary support component 014 above the mulch film 102, seal the mulch film 102 and the top film 101 to enclose and form a storage space, and place the stored item 200 in the storage space.

[0067] After the top membrane 101 is inflated, the inflatable frame can be moved to place the top membrane 101 above the item to be stored 200. Tighten the airtight zipper between the ground membrane 102 and the top membrane 101 to connect the curtain body and the curtain fixing piece.

[0068] S5: A tensioning strap 002 is installed on the outside of the top membrane 101. The two ends of the tensioning strap 002 are connected to the ground on both sides of the top membrane 101. An insulation cover 010 is laid on the outside of the top membrane 101.

[0069] The tensioning strap 002 is wrapped around the top membrane 101, and its two ends are connected to two anchors 015 to connect the tensioning strap 002 to the ground. An insulation cover 010 is laid on top of the top membrane 101. The edge of the insulation cover 010 can be pressed against the ground or the insulation layer 012 by gravity to insulate the accommodating space.

[0070] S6: Place air conditioning unit 007, controlled atmosphere unit 009 and ventilation unit 008 on the ground, and connect them to the accommodating space.

[0071] Place or fix the air conditioning unit 007, the controlled atmosphere unit 009, and the ventilation unit 008 on the ground or the waterproof layer 013, connect the air conditioning unit 007 and the ventilation unit 008 to the accommodating space, and connect the controlled atmosphere unit 009 to the accommodating space through the air duct 902.

[0072] S7: Control the air conditioning unit 007 to inflate the accommodating space and retract and remove the auxiliary support component 014.

[0073] After the accommodating space is inflated, the top membrane 101 bulges upward under the action of the air pressure inside the accommodating space, that is, the membrane material component 001 expands due to the internal air pressure. At this time, the inflatable frame can be deflated, contracted, and removed.

[0074] During the process, air tightness testing can be performed. For example, the air pressure in the containment space can be increased to 250 Pa, and the half-life can be monitored. If the half-life is shorter than the preset time, the air tightness is judged to be poor; otherwise, the air tightness meets the requirements.

[0075] S8: Controls the operation of the controlled atmosphere unit 009 and the ventilation unit 008 to regulate the concentration and uniformity of the inert gas in the containment space.

[0076] Controlled atmosphere unit 009 introduces an inert gas, such as nitrogen, into the containment space to reduce the oxygen concentration until it falls below 2%. Ventilation unit 008 can accelerate the flow of gas within the containment space, improving the uniformity of the gas flow.

[0077] S9: Start control component 016, monitor oxygen concentration in the storage space, and when the oxygen concentration is higher than the preset oxygen concentration, control the controlled atmosphere unit 009 to replenish inert gas in the storage space; monitor the temperature of more than 200 places of the stored items, and when the temperature difference is greater than the preset temperature difference, control the ventilation unit 008 to work; record controlled atmosphere data and temperature data.

[0078] The oxygen concentration in the storage space is detected by oxygen concentration sensor 905. When the oxygen concentration is higher than the preset oxygen concentration, such as 3% or 2.5%, the controlled atmosphere unit 009 is activated to supplement inert gas and maintain an inert gas environment in the long term. The temperature and humidity in the storage space are detected by temperature and humidity sensors 903. Multiple temperature and humidity sensors 903 can be installed within the item to be stored 200 to monitor the temperature and humidity at multiple points within the item. When the temperature difference in the item to be stored 200 is large, such as when the range of multiple temperature data exceeds the preset temperature difference, the ventilation unit 008 is activated to increase gas flow and make the temperature of the item to be stored 200 more uniform. When the humidity in the item to be stored 200 is high, the air conditioning unit 007 can be activated to dehumidify.

[0079] S10: After storage, remove the stored item 200 and store the membrane component 001, insulation component and environmental control component.

[0080] When control component 016 is working, it records various data in real time, such as temperature and humidity data, gas concentration data, the operating status of air conditioning unit 007, controlled atmosphere unit 009, and ventilation unit 008, and the opening degree of the first air volume control valve 801 and the second air volume control valve 901. Based on the monitored data, it can automatically generate a full-cycle digital archive, facilitating the analysis of the storage process.

[0081] After inspection and cleaning, membrane component 001 can be folded and stored, and the storage system can be transferred to the next location for reuse.

[0082] The embodiments of this application have a variety of green grain storage methods, such as intelligent temperature control, long-term slow-release preservation, controlled atmosphere storage, low-temperature storage, and physical control of rodents, insects and mold. They have the advantages of rapid deployment and flexible relocation, do not require traditional infrastructure, are suitable for small-scale storage needs with high standards of flexibility and preservation, and can also achieve unattended operation, reducing maintenance costs.
