Definitions
- the invention relates to a method of manufacturing objects from vegetable raw material. It aims to make objects such as containers, packaging, panels or plates, in particular for the construction or furnishings, which, while benefiting from durability and stability compatible with their function, are biodegradable, compostable and recyclable.
- biodegradable is meant that said object is likely to be degraded at least for the most part by microorganisms natural when put in the right conditions, without release of toxic products for the ecosystem, and at the scale of a few weeks to months.
- compostable is meant an object which, divided, homogenized and mixed with organic matter and / or soil, provides a nutritious non-toxic substrate for plants.
- recyclable is meant an object whose material can be reused to form an object of the same range.
- the present invention proposes to overcome the disadvantages of known methods and to indicate a new method allowing to make a biodegradable, compostable and recyclable object in remarkable saving conditions.
- Another object of the invention is to manufacture an object which has good flexural strength compatible with uses in construction, furniture, packaging, packaging ...
- the manufacturing process according to the invention consists in (a) using a sunflower or rapeseed meal having a content weight by oil of less than 20% and a protein content by weight greater than 15%, hydrated so as to present a weight rate of hydration substantially between 5% and 55%, (b) press forming said cake in a shape adapted to that of the desired object and (c) to produce a heat treatment or drying treatment to ensure stiffening of the shaped object.
- “Sunflower or rapeseed meal” means usual way the solid residue from oil extraction from sunflower seeds or whole or shelled rapeseed, whatever the means of extraction (pressing, solvent extraction ...), this oil extraction can be total or partial but lowering the oil content by weight of the product below a threshold generally around 20%; the meal may or may not have been the subject of a preliminary partial extraction of protein, its protein content by weight however, remaining above 15%. (All weight contents are expressed as a percentage relative to the weight of dry matter; the rate of hydration is expressed in relation to the total matter).
- the method of the invention can be implemented by operating thermoforming of the cake, consisting of bringing it, during pressing, to a temperature substantially between 130 ° C and 200 ° C.
- thermoforming is carried out at a pressure substantially between 15 and 25 megapascals. A such thermoforming process is faster than forming cold (discussed later) and leads to better mechanical resistance.
- oil cake sunflower or rapeseed is preferably subjected to a treatment mechanics of division and homogenization to give it a distribution particle size such that the median diameter of the particles D50 is substantially between 0.1 mm and 1 mm.
- median diameter D50 we means a diameter such that 50% of the particles by weight pass through a sieve vibrating with a mesh side equal to said diameter. (All measures particle size are carried out on the dry matter).
- thermoforming sunflower meal or rapeseed meal panels usable in the construction, mainly consisting of plant fibers linked by proteins, having a flexural strength substantially between 10 and 25 megapascals.
- the meal previously subjected to a mechanical division treatment and homogenization to give it a particle size distribution such as median particle diameter D50 is less than 1mm, is hydrated, by a addition of water, at a hydration rate substantially between 25% and 50% in order to obtain a plastic paste which is then cold formed by pressing before being dried until hardening.
- the forming pressure can advantageously be adjusted between 1 and 5 megapascals.
- the residual oil from the oil cake has an unfavorable effect on the forming and qualities of objects obtained, and an oil cake is advantageously used at least partially deoiled, with an oil content by weight of less than 10%.
- an oil-depleted oil cake from the crushing of sunflower or rapeseed. (We generally mean by "exhausted cake in oil "a cake containing at most 2% oil). We limit or delete thus the hydrophobic repulsive forces which tend to oppose fiber / protein association.
- the meal can in particular be divided and homogenized, and possibly at least partially de-oiled, by passing through a twin-screw device comprising, from upstream to downstream, shearing means, means crushing, means for withdrawing the liquid phase, at least one module not inverted to achieve axial compression of the solid materials, and a solids outlet, said twin-screw device being furthermore equipped with means water injection to adjust the hydration rate of the meal.
- a twin-screw device comprising, from upstream to downstream, shearing means, means crushing, means for withdrawing the liquid phase, at least one module not inverted to achieve axial compression of the solid materials, and a solids outlet, said twin-screw device being furthermore equipped with means water injection to adjust the hydration rate of the meal.
- Such treatment refines the texture of the meal and allows the association of fibers and proteins to be generated under optimal conditions during forming.
- Sunflower or rapeseed meal may if necessary be enriched with vegetable fibers in order to further lower the cost price of objects obtained.
- This method of implementation which makes it possible to value stocks existing low-value vegetable fibers (straw, sunflower shell) will be especially used when using a meal containing all its proteins original (without partial extraction) or when the object sought is not submitted to severe mechanical strength requirements.
- the method of the invention makes it possible to manufacture objects of very diverse type: flat objects such as panels, plates, supports, spacers ..., hollow objects such as containers, packaging ...
- the twin-screw device shown diagrammatically in Figures 1 and 2 is used to carry out the prior preparation of the cakes in Example 1; these measures is obtained from modules sold by the company "CLEXTRAL" (registered trademark) under the general reference "BC45".
- Each module includes a double-walled tubular enclosure 1 and 2 which allows thermal regulation from the heart of the enclosure where the active organs are housed.
- Some modules are type comprising two identical co-penetrating screws, others of the type comprising shear mixers composed of two-lobed discs.
- the various modules are rotated in synchronism by an electric motor 3 allowing obtain a speed of rotation of its output shaft which can reach 700tr / min. In the examples, the speed of rotation chosen is 100 rpm.
- the conventional type mold shown diagrammatically in FIG. 3 is intended to carry out a cold forming as described in Example 1.
- This mold comprises, on the one hand, a hollow form 17, in the frustoconical example, fixed on a press plate 18 and having a removable bottom 19 to facilitate the demoulding, on the other hand, a conjugate counterform 20 fixed on the other plate 21 of the press. Correct positioning of the form and counter-form is ensured by a centering pin 22. Molding and demolding are carried out cold.
- the conventional type mold shown diagrammatically in FIG. 4 is intended to carry out a thermoforming as described in Example 2, in order to obtain a hollow object of the same shape as in Example 1.
- This mold is similar to that of Figure 3, except that the inner wall of the hollow form is equipped with a grid 23 for evacuating steam and the bottom of a frit 24 connected to a duct 25 steam outlet. These forms and counter-forms are arranged in a heating press (not shown).
- a weak play about 1 mm is preserved above the hollow form to allow steam evacuation.
- the conventional type mold shown diagrammatically in FIG. 5 is intended to carry out thermoforming of a panel as described in Example 3.
- This mold comprises, first of all, a form 26 combined with that of the panels desired, the bottom of which consists of a removable base 27 fitted with a sinter 28 connected to a water vapor discharge duct 29.
