Description

Field of invention [001] This descriptive report refers to a utility model patent that relates generally to the field of fruit pulping machines, intended to facilitate the process of separating the seeds and pulp of fruits, particularly drupes, preferably açaí. Fundamentals of innovation [002] In the field of fruit pulpers, preferably of açaí (Euterpe oleracea Mart.), which is an Amazonian palm tree, açaí is “(...) a food rich in proteins; fiber; lipids; minerals, such as manganese, copper, boron and chromium, and in vitamin E, a natural antioxidant that acts in the elimination of free radicals” (CARVALHO, Ana Vânia. Nutritional aspects. Embrapa, 2021. Available at: https://www.embrapa.br/agencia-de-informacao-tecnolo-gica/cultivos/acai/pos-producao/processamento/aspectos-nutricio- nais#:~:text=Esse%20aumento%20pode%20ser%20atribu%C3%ADdo,na%20eli- mina%C3%A7%C3%A3o%20dos%20radicais%20livres. Accessed on: 08/08/2024.). where açaí is a drupe comprising an outer layer, a fleshy layer, and a hard shell layer that surrounds a seed. [003] The addition of water to the pulping process of drupes, preferably açaí, has problems with regard to the physical properties of the product, since the addition of water in the process dilutes the tannic acid in the pulp, which results in the acceleration of the oxidation of the pulp, giving it a brown color characteristic. [004] The machine of the present invention has a wide advantage because, by not using liquids in the pulping process, it eliminates the need for subsequent processes; in which the liquids used in this procedure, in other techniques, need to be subsequently removed from the final product. In addition, other techniques process the pulp together with the pit of the fruit, for example, by beating, also requiring prior softening of the fruit to be pulped. [005] The machine, according to the present innovation, separates the pit from the drupe with the tangential force of the external and internal cones applied to the drupe. Therefore, without the need for prior softening of the drupe or the beating of the pit with the pulp. In this way, the present innovation guarantees speed in the drupe pulping process by up to 80% compared with other processes. Description of the drawings [006] Figure 1 shows a perspective view of the machine (1) for de-pulping açaí. [007] Figures 2 and 2A show a front view and a side view of the machine (1) for pulping açaí. [008] Figure 3 shows a perspective view of the feeder module (3) comprising the feeder screw (3a) and a feeder motor (3b). [009] Figure 4 shows a perspective view of an outer cone (4), comprising an outer cone casing (4a) and an outer cone motor (4b). [010] Figure 5 shows a perspective view of an inner cone (5), comprising an inner cone casing (5c), an inner cone shaft (5b) and an inner cone motor (5a). [011] Figure 6 shows a perspective view of the structure (E) of the machine (1), wherein the structure (E) comprises a feed funnel (2), a fixed structure (6), an outlet nozzle (7) and guides (8). [012] Figure 7 shows a perspective view of a mobile group (9), comprising a mobile group drive (9a), a mobile group structure (9b) and mobile group guides (9c). Detailed description of the invention [013] According to the present innovation, Figure 1 shows a perspective view of the machine (1), preferably for pulping açaí, in which, according to the present innovation, the drupe is inserted into the feeder module (3) entering a feed funnel (2) and passing through the feed screw (3a), which are coupled to a fixed structure (6), in which, as it passes through the outer (4) and inner (5) cones, the drupe, with the pressure of the coaxial movement of the parts, is forced into a rotary and compressive movement, applied by the tangential force of the inner (5) and outer (4) cones to the drupe, and undergoes the pulping process, being then directed to the outlet nozzle (7). The inner cone (5) performs only rotation, while the outer cone (4), which is fixed to the moving group, can both rotate and move axially. [014] Also according to the present innovation, the pressure of the axial movement of the inner (5) and outer (4) cones is activated by an external force, preferably a pneumatic external force. [015] Also according to the present innovation, Figures 2 and 2A show a front view and a side view of the machine (1) for depulping açaí, in which in view 2A a better arrangement between the outer cone (4) and inner cone (5) can be observed, both having a relative movement to each other to add to the tangential force that will depulp the drupe. [016] In Figure 3, according to the innovation, a perspective view of the feeder module (3) is presented, comprising a feeder screw (3a) and a feed motor (3b), both of which are arranged in the fixed structure (6) and connected by guides (8) to the structure (E) of the machine (1), the rotary movement of the same being made with the aid of a transmission chain (10) connected to a flange (11) fixed to t
