Description

Technical Field

[0001] The utility model relates to the technical field of nut processing, in particular to a thin-shell pecan pretreatment device. Background Art

[0002] Thin-shell pecans are a popular variety of nuts. Their fruits are not only nutritious, but also have a strong milky flavor and a mellow and crispy taste. The pretreatment of thin-shell pecans usually includes picking, shelling, cleaning, screening, de-astringency and drying. Among them, drying is an important step, using a drying device to remove excess water from the fruit for easy storage and subsequent processing.

[0003] After the thin-shell pecans are pre-treated and cleaned, they are dried by a drying device. Impurities such as empty seeds, shriveled grains and debris will remain on the thin-shell pecans taken out after cleaning. The adhesion of these impurities not only leads to a decrease in drying efficiency during drying, but also affects the subsequent processing of the pecans after drying. Therefore, improvements are now made to the thin-shell pecan pre-treatment device. Utility Model Content

[0004] The utility model aims to propose a thin-shell pecan pretreatment device in order to solve the problem that the existing pecan has low drying efficiency due to the adhesion of impurities in the pretreatment and drying process, which affects the subsequent processing.

[0009] As a further description of the above technical solution: the oven mechanism includes a drying oven, a heating component is arranged on the drying oven through a cover plate, and a notch is opened in the middle position of the cover plate.

[0010] As a further description of the above technical solution: the heating component includes a mounting base fixed to the lower side of the cover plate, an electric heating tube is arranged inside the mounting base, a protective net is arranged at the bottom of the mounting base, and a wiring socket is arranged at one end of the mounting base.

[0012] The driving assembly comprises a pair of bracket plates fixed on the side surfaces of the cover plate, a screw rod arranged along the length direction of the slot is rotatably connected between the pair of bracket plates through a motor, and a sliding seat matching the screw rod is arranged on the screw rod.

[0013] As a further description of the above technical solution: the bottom end of the turning fork is located in the drying box near the bottom of the drying box, and the spacing size of the fork teeth of the turning fork is larger than the particle size of the pecan.

[0014] As a further description of the above technical solution: the filter assembly includes an installation box connected to the air inlet of the induced draft fan through a through opening, a safety net is provided on one end of the installation box away from the through opening, and a filter net is provided in the middle of the interior of the installation box.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Reference Figure 1-Figure 6 The present embodiment provides a thin-shell pecan pretreatment device, comprising an oven mechanism 1 for drying pecans, a turning mechanism 2 for turning the pecans in the oven mechanism 1, and a dust removal mechanism 3, the dust removal mechanism 3 comprising an axial flow fan 31 and an induced draft fan 32 symmetrically arranged along the length direction of the oven mechanism 1, the axial flow fan 31 and the induced draft fan 32 form an axial flow airflow in the oven mechanism 1, and a filter component 33 for filtering residual debris on the pecans is arranged at the air inlet position of the induced draft fan 32.

[0029] In the utility model, the cleaned pecans are placed in the oven mechanism 1 for heating and drying. During the drying process, the turning mechanism 2 continuously turns the pecans in the oven mechanism 1 to ensure that the heat can fully act on the pecans. At the same time, the axial flow fan 31 and the induced draft fan 32 generate axial flow airflow in the oven mechanism 1. The axial flow airflow can accelerate the flow speed of the air on the surface of the pecans, further improving the drying speed. Moreover, with the flow of the axial flow airflow, the impurities remaining on the surface of the pecans will be drawn into the filter component 33 of the induced draft fan 32, thereby removing the impurities remaining on the pecans, greatly improving the drying efficiency of the pecans.

[0030] Specifically, refer to Figure 2The oven mechanism 1 includes a drying box 11, on which a heating assembly 14 is provided through a cover plate 12, and a notch 13 is provided in the middle of the cover plate 12. When the pecans are dried, the pecans are poured into the drying box 11, and then the cover plate 12 is covered, and the heating assembly 14 is used for heating and drying. The notch 13 can ensure that the turning mechanism 2 can extend into the drying box 11, so that the pecans in the drying box 11 are turned during the drying process.

[0031] Among them, refer to Figure 3 The heating assembly 14 includes a mounting seat 141 fixed to the lower side of the cover plate 12, an electric heating pipe 142 is arranged inside the mounting seat 141, a protective net 143 is arranged at the bottom of the mounting seat 141, and a wiring seat 144 is arranged at one end of the mounting seat 141. The wiring seat 144 allows the electric heating pipe 142 to be connected to an external power supply. When the pecans are dried, the electric heating pipe 142 is started to heat and dry, and the protective net 143 can prevent the pecans from hitting the electric heating pipe 142 during the turning process, thereby protecting the electric heating pipe 142.

[0032] Specifically, refer to Figure 1 and Figure 4 The turning mechanism 2 includes a driving assembly, and a turning fork 25 extending into the drying box 11 is provided on the output end of the driving assembly; the turning fork 25 is moved by the driving assembly, so that the piled pecans can be turned when the pecans are dried, ensuring that the heat can fully act on the pecans and improving the drying efficiency.

[0033] The driving assembly includes a pair of bracket plates 21 fixed to the upper side of the cover plate 12, and a screw rod 23 arranged along the length direction of the slot 13 is rotatably connected between the pair of bracket plates 21 through a motor 22, and a slide seat 24 matching the screw rod 23 is provided on the screw rod 23. The motor 22, the screw rod 23 and the slide seat 24 form an electric screw structure, so that the turning fork 25 can reciprocate in the drying box 11, and then the material can be turned continuously, effectively improving the drying efficiency.

[0034] The bottom end of the turning fork 25 is located in the drying box 11 near the bottom of the drying box 11, and the spacing of the tines of the turning fork 25 is larger than the particle size of the pecan. The turning fork 25 near the bottom of the drying box 11 can ensure that the pecans accumulated in the drying box 11 are fully turned over, and the pecans are continuously turned over as the turning fork 25 moves. The spacing of the tines of the turning fork 25 ensures that the pecans can pass through the tines, thereby achieving better turning.

[0035] Specifically, refer to Figure 5 and Figure 6The filter assembly 33 includes an installation box 331 connected to the air inlet of the induced draft fan 32 through a through hole 334. A safety net 332 is provided at one end of the installation box 331 away from the through hole 334, and a filter net 333 is provided in the middle of the installation box 331. The axial flow fan 31 blows air to the induced draft fan 32, and the induced draft fan 32 simultaneously extracts air, thereby generating an axial flow airflow in the drying box 11, further sucking the residual impurities attached to the pecans into the installation box 331, and filtering them through the filter net 333. The aperture of the safety net 332 is smaller than the particle size of the pecans and larger than the aperture of the filter net 333, so that the safety net 332 can shield the pecans without affecting the impurities from entering the installation box 331.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
