DESCRIPTION

of the patent for industrial invention entitled ?UNITA? OF GROWTH OF SEEDS?

FIELD OF TECHNIQUE

The present invention relates to the sector of cultivation of vegetable products, preferably in the agri-food sector.

In particular, the present invention ? relating to the growth of seeds for the cultivation of vegetable products. Pi? in particular, the present invention ? relating to the growth of seeds for the cultivation of edible vegetable products.

DESCRIPTION OF THE STATE OF THE ART

Techniques are known and widely used which provide for the cultivation of vegetables and/or vegetables to guarantee their supply in every season, for example the known techniques of cultivation in greenhouses.

more and more Soilless indoor cultivation techniques are also widespread, for example in the home, which are particularly practical for the end user.

Some techniques of this type, including crops known as hydroponic crops or aeroponic crops, use particular equipment, or enhancers, which define a controlled environment for the cultivation of plant products.

In these known systems, the seeds of the product to be grown are preferably placed on a growing substrate inside suitable containers which are sealed so as to provide a unit/package which the user can subsequently open and advantageously insert inside the designated enhancer.

The substrate comprises, for example, a loam or a matrix of natural and biodegradable fibers which is suitably irrigated and possibly added with fertilizers and/or the biological manures necessary for the plant product to germinate and ripen.

In other cases, the unit/package is simply opened and left in the open air to allow the plant product to sprout and ripen with the addition of water. A first problem related to known systems? the possibility? that the substrate is affected by any contaminants present in the environment, for example bacteria, spores or single contaminating cells during the sprouting or maturation of the plant product.

There? prevents healthy growth of the plant product.

Another drawback associated with systems of the known type? relating to the conservation of seeds inside the units? from the moment of their packaging to the moment of their use by the user.

DETAILED DESCRIPTION OF PREFERRED SHAPES

CARRIED OUT OF THE PRESENT INVENTION

While the present invention is described below with reference to preferred embodiments thereof shown in the drawings, the present invention is not limited to the embodiments described below and shown in the tables. On the contrary, the embodiments described and represented clarify some aspects of the present invention, the object of which is defined by the claims.

The present invention is? proved to be particularly advantageous with reference to the use of the unit? of growth of the invention for the germination and growth of an edible vegetable product in an edible substrate in such a way that the vegetable product and the substrate can be harvested and eaten directly, effectively constituting a portion of food.

With reference to figure 1 ? shown a unit? growth tube 10 according to a preferred embodiment of the invention.

The unit growth plate 10 according to the invention allows the cultivation of vegetable products P on a cultivation substrate 12, as illustrated for example in figure 2 in which the vegetable products P are shown in an advanced phase of growth after germination and extracted from the unit? of growth 10 or as illustrated in figure 4 in which the vegetable products P are shown in an advanced phase of growth still inside the unit? of growth 10.

Preferably, the unit? of growth 10 according to the invention allows the cultivation of edible/edible vegetable products P, such as for example vegetables, mushrooms, and more? preferably also the substrate 12 ? edible, as better described below.

In the case of use of an edible substrate, advantageously, following the germination and growth of the vegetable product P, the product P and the substrate can be collected and eaten directly, effectively constituting a portion of food.

In general, however, by vegetable products P we mean any vegetable for edible and/or ornamental use, therefore not only products such as vegetables, mushrooms, but also flowers, ornamental plants, etc.

The unit growth tube 10 according to the preferred embodiment of the invention preferably comprises a casing 20 which defines a closed internal volume V, at least one cultivation substrate 12 received in this closed internal volume V and seeds S associated with the cultivation substrate 12, such as shown in figure 3.

The cultivation substrate 12 with relative seeds S according to the preferred embodiment shown and described? preferably consisting of one or more? substantially truncated cone-shaped substrates each comprising corresponding seeds S.

In embodiment variants, however, the number of substrates may be different, at least one substrate, as well as the shape of the substrate(s).

The casing 20 preferably comprises a first part 22, or lower part, suitably shaped to receive the growing substrates 12. Therefore, the lower part 22 preferably comprises more than one part; seats 24 suitable for receiving the corresponding substrates 12.

Pi? preferably, the lower part 22 comprises more? seats 24 of substantially frusto-conical shape suitable for receiving the corresponding frusto-conical substrates 12.

In embodiment variants, obviously, the number and/or shape of these seats could be different according to the shape of the corresponding substrates to be received.

The lower part 22 preferably has an opening 26 which, in the illustrated embodiment, substantially affects the entire upper area of the lower part 22.

The lower part 22 is therefore open at the top to favor the introduction of the substrates 12 with the respective seeds S.

The casing 20 then preferably comprises a second part 30 for closing said opening 26. This second part 30 preferably comprises a closing film 30. The lower part 22 preferably has an edge 28 which peripherally delimits the opening 26 and which favors the application of the sealing film 30, for example by gluing or heat sealing depending on the material used to make the two parts 22, 30.

In a preferred embodiment, the two parts 22, 30 are made of amorphous polyethylene terephthalate (APET).

In embodiment variants, other materials may be used, such as for example PP, PE, PA, PET, PEHD and CPLA or combinations thereof.

Furthermore, preferably, the lower part 22 and/or the second closure part 30 are at least partially transparent. The casing 20 according to the invention ? preferably shaped to allow the permeation of air from the external environment towards the internal volume V and to prevent the passage from the external environment towards the internal volume V of contaminating elements present in the air.

According to one aspect of the present invention, therefore, the casing 20 comprises a permeation zone 60 suitable for allowing the permeation of air from the external environment towards the internal volume V and suitable for preventing the passage from the external environment towards the internal volume V of contaminating elements present in the air and/or on the surfaces adjacent to the permeation zone 60.

By contaminating elements we mean those biological elements which, when in direct contact with vegetable products, are harmful to the sprouting and/or growth of vegetable products.

The contaminating elements include one or more? of elements of the group comprising: bacteria and their spores, fungi and their spores, molds and their spores, yeasts.

According to the preferred embodiment illustrated and described, the permeation zone 60 is preferably made in the second part 30.

The permeation zone 60 ? preferably defined by a plurality? of holes 64, or micro-holes, defined directly on the second part 30 of the casing 20.

Preferably, these holes 64 have a diameter of between 50 and 150 microns, more preferably between 80 and 120 microns, even more? preferably a value equal to 100 microns.

In embodiment variants, the permeation zone can be made differently. For example, as shown in the alternative embodiment of figure 11, the permeation zone 260 can be defined by a hole 262 made in the second part 230 of the casing 220 and a filter 264 closing this hole 262.

According to an advantageous aspect of the invention, preferably, the preparation of the unit? 10 allows the atmosphere of the internal volume V to be kept protected from the external environment.

The unit of growth 10 cos? prepared allows to keep the seeds S and/or the substrate 12 in a protected environment.

The protected atmosphere is maintained inside the casing 20 thanks to the characteristics of the materials which make up the various parts of the casing 20, and in particular to the characteristics of the permeation zone 60 as stated above.

Once the preparation of the unit? of growth 10 with seed S and substrate 12, the phases of sprouting and growth of the plant products P can begin.

Inside the envelope 20, the vegetable product P can grow until they reach full maturity, as shown in figure 4.

During the growth, preferably, the gaseous exchange between the external environment and the internal volume V, thanks to the presence of the micro-holes 64 and the respective filtering function, takes place in a controlled way, protecting the internal volume V from any contaminants present in the environment, for example, it prevents the passage of bacteria and their spores, fungi and their spores, molds and their spores, yeasts in quantity? such as to be harmful to vegetable products P. The seeds S, therefore, germinate and grow inside the internal volume V in a protected atmosphere.

When is the plant growth cycle? completed, for example in the condition shown in figure 4, you can? remove the sealing film 30 and take, for consumption, the substrate 12 with the overgrown vegetable product P, as shown in figure 2.

In a preferred embodiment, when it is decided to use the unit? of growth 10, the? unit? ? preferably placed in a controlled environment, for example at a controlled temperature, from 18 to 28°C, and exposed to sunlight and/or artificial light. The partial transparency of the lower part 22 and/or of the second closure part 30 favors this phase with exposure to light.

Preferably, before its use, the unit? 10 of growth is kept at a controlled temperature between 1 and 4 ?C which substantially prevents the germination of the seeds S.

In a mode? preferred, the conservation phase and the subsequent phases of sprouting and growth are managed by a producer/grower who subsequently makes the unit available 10 of growth with the mature vegetable product P to the consumer.

The task of the consumer will be that of removing the sealing film 30 and removing, for consumption, the substrate 12 with the vegetable product P grown above.

In the following and by way of example are schematically described the phases of preparation of the unit? growth tube 10 up to its use according to a preferred embodiment of the invention:

- positioning of the substrates 12 inside the first part 22 of the casing 20;

- sowing of the substrates 12 with seeds S;

- closure of the envelope 20 by applying on the first part 22 the closure film 30 provided with a permeation zone 60;

- conservation of the unit? 10 before its use, preferably keeping the unit? 10 at a controlled temperature of 1 to 4 ?C.

In a preferred embodiment, before positioning the substrates 12 inside the first part 22 of the casing 20, the first part 22 is advantageously sterilized, for example by chemical (hydrogen peroxide) or physical (treatment with ozone ) or thermal (steam sterilization).

In a preferred embodiment, before sowing the seeds S are advantageously sterilized, for example by ozone or with a sodium hypochlorite solution or with a hydrogen peroxide solution.

These sterilization operations make it possible to minimize the presence of bacteria, spores or other biological contaminants.

In a preferred embodiment, the substrate 12 used for the unit? of growth 10 ? a pre-hydrated substrate. Preferably, the substrate 12 comprises an amount of water suitable for guaranteeing the germination and/or growth of the plant product P.

Advantageously, the use of a pre-hydrated substrate allows the germination and/or autonomous growth of the plant product P inside the unit. 10 without the need for further operations.

In a preferred embodiment, the edible substrate has the consistency of a gel. In this case, preferably, the quantity? of water ? present in a percentage by weight with respect to the weight of the edible substrate higher than 90%.

The edible substrate can however, have different consistencies and include, for example, elements in suspension and/or solid parts in variable percentages.

The quantity? of water will be in general preferably present in a percentage by weight with respect to the weight of the edible substrate greater than 30%.

For the realization of the edible substrate 12 one or more are preferably used of the following components, or an appropriate combination thereof:

- a natural thickener, preferably a compound of natural substances derived from cellulosic polysaccharides extracted from fruit peels and various vegetables and/or agar-agar;

- a natural food preservative, preferably essential oils, for example: oregano oil, rosemary oil, thyme oil;

- a chemical food preservative, preferably potassium sorbate;

- protein hydrolysates;

- a natural food preservative, preferably essential oils, for example: oregano oil, rosemary oil, thyme oil;

- a chemical food preservative, preferably potassium sorbate;

- protein hydrolysates;

- natural food flavourings, preferably dry extract of vegetable parts;

- food supplements, for health and/or sport, preferably vitamins and/or mineral salts.

With reference to figures 5 to 10 ? shown and described a constructional variant of the unit? of growth 110 according to the invention. Component parts corresponding or equivalent to the first embodiment are identified by the same reference numerals.

This embodiment differs from the previous embodiment in that the permeation zone 60 is associated with removable sealing means 70. The sealing means 70 is adapted to be arranged on the permeation zone 60 in a first sealing configuration, as shown in figure 5, able to make the permeation zone 60 effectively also impermeable towards the internal volume V and in a second configuration, when removed, suitable to allow the permeation of air from the external environment towards the internal volume V, as shown in figures 8 and 9.

The sealing means 70 preferably comprise a laminar element 70, or seal 70, applied to the casing 20, more preferably applied to the second part 30 (closure film 30) of the casing 20. The laminar element 70 has the part 70a facing the closure film 30 of the adhesive type so to be applied and subsequently removed by the user.

The laminar element 70 ? also made of a material suitable for making the permeation zone 60 impermeable towards the internal volume V. The laminar element 70 ? preferably made of PP, PE, PA, PET, PEHD and CPLA or combinations thereof.

When the unit? of growth 1 10 is prepared, cos? as shown in figure 5 , the sealing means 70 is in its first sealing configuration. Therefore, in this configuration, the envelope 20 as a whole defines a barrier suitable for making the internal volume V waterproof from the external environment and in particular a barrier for the cultivation substrate 12 and the relative seeds S.

According to one aspect of the invention, preferably, the preparation of the unit? 1 10 allows you to keep the atmosphere of the internal volume V protected from the external environment.

The unit of growth 1 10 cos? prepared allows to keep the seeds S and/or the substrate 12 in a protected environment.

The protected atmosphere is maintained inside the casing 20 thanks to the characteristics of the materials which make up the various parts of the casing 20, as mentioned above.

To use the unit? of growth 110 the seal 70 is removed, as shown for example in figures 8 and 9.

The removal of the seal 70 allows the exchange of air between the external environment and the internal volume V through the filter 64 and the seeds S receive the supply of oxygen sufficient to start the metabolic processes of growth.

Inside the envelope 20, the vegetable product P can therefore grow until preferably reaching full maturity, as shown in figure 10.

When is the plant growth cycle? completed, can you? remove the sealing film 30 and take, for consumption, the substrate 12 with the vegetable product P grown above.

Preferably, the gaseous exchange between the external environment and the internal volume V, thanks to the presence of the filter 64 and the respective filtering function, takes place in a controlled way, protecting the internal volume V from any contaminants present in the environment, for example it prevents the passage of bacteria and their spores, fungi and their spores, molds and their spores, yeasts in quantity? such as to be harmful to vegetable products P. The seeds S, therefore, germinate and grow inside the internal volume V in a protected atmosphere. In a preferred embodiment, when it is decided to use the unit? of growth 110, the unit? ? possibly placed in a controlled environment, for example at a controlled temperature, from 18 to 28°C, and exposed to sunlight and/or artificial light.

Advantageously, at the time of the subsequent use of the unit? 10 with the removal of the seal 70, the gaseous exchange between the external environment and the internal volume V is favored through the filter 64.

In a mode? preferred, the preparation of the unit? of growth 110 ? managed by the producer/grower who subsequently makes the unit available? 1 10 to a consumer.

The user/consumer then removes the seal 70 to complete the subsequent stages of sprouting and growth and obtain the desired mature vegetable product P.

In the following and by way of example are schematically described the phases that go from the preparation of the unit? of growth 1 10 up to its use according to a preferred embodiment of the invention:

- positioning of the substrates 12 inside the first part 22 of the casing 20;

- sowing of substrates with seeds S;

- closure of the wrapper 20 by applying on the first part 22 the closure film 30 provided with a permeation zone 60 and a seal 70;

- conservation of the unit? 1 10 before its use, preferably keeping the unit? 1 10 at a controlled temperature of 1 to 4 ?C;

- use of the unit? 1 10 by removing the seal 70. The removal of the seal 70 initiates the germination process of the seeds S and the subsequent germination and growth of the plant product P in a protected atmosphere.

As previously stated, in a preferred embodiment, before positioning the substrates 50 inside the first part 22 of the casing 20, the first part 22 is advantageously sterilized, for example by chemical (hydrogen peroxide) or physical ( treatment with ozone) or thermal (sterilization with steam).

In a preferred embodiment, before sowing the seeds S are advantageously sterilized, for example by ozone or with a sodium hypochlorite solution or with a hydrogen peroxide solution.

These sterilization operations make it possible to minimize the presence of bacteria, spores or other biological contaminants.

In a preferred embodiment, the substrate 12 used for the unit? of growth 1 10 ? a pre-hydrated substrate. Preferably, the substrate 12 comprises an amount of water suitable for guaranteeing the germination and/or growth of the plant product P.

Advantageously, the use of a pre-hydrated substrate allows the germination and/or autonomous growth of the plant product P inside the unit. 110 without the need for further operations.

In a preferred embodiment, the edible substrate has the consistency of a gel. In this case, preferably, the quantity? of water ? present in a percentage by weight with respect to the weight of the edible substrate higher than 90%.

The edible substrate can however, have different consistencies and include, for example, elements in suspension and/or solid parts in variable percentages.

The quantity? of water will be in general preferably present in a percentage by weight with respect to the weight of the edible substrate greater than 30%.

For the realization of the edible substrate, one or more? components, as described above.

A particular advantageous use of the substrate according to the invention refers to the cultivation of so-called microgreens, for example bay leaf, microgreen, sprouts etc.

The germination and/or growth of the product? guaranteed, preferably, by the quantity? of water which pre-hydrates the substrate. The plant product P preferably takes nourishment from the composition of the seed from which it sprouts. In the event that the substrate contains vegetable protein hydrolysates, as mentioned above, the germination and/or growth of the plants? further favored.

As mentioned, thanks to the presence of the edible substrate following the autonomous germination and growth of the vegetable product P, the product and the substrate can be collected and eaten directly, effectively constituting a portion of food.

The components used for the substrate, such as for example protein hydrolysates or food flavorings or food supplements, also make it possible to give each dose of food a particular characteristic in terms of taste and/or properties? nutrients and at the same time provide a completely natural genuine and healthy food.

With reference to figure 1 1 ? shown another embodiment of the unit? of growth 210 according to the invention. Component parts corresponding or equivalent to the first embodiment are identified by the same reference numerals.

This embodiment differs from the embodiment shown in Figures 1 to 5 in that the permeation zone 260 is not? defined by microholes but ? defined by a hole 262 made in the second part 230 of the casing 220 and a filter 264 closing this hole 262.

? it is evident that also for this embodiment it will be possible provide for the use of sealing means, similarly to what was previously described.

From what was said? it is clear that the growth system according to the invention allows to achieve the intended purposes.

In particular, ? It is clear that the proposed solution guarantees the optimal conservation of seeds from the moment of its packaging and the optimal growth of the plant product, both by the producer and by a possible final user/consumer.

Although the invention has been described with reference to the accompanying drawings, it may undergo modifications in the manufacturing phase, all falling within the same inventive concept expressed by the claims set out below and therefore protected by the present patent.
