Description

TECHNICAL FIELD

[0001] The utility model relates to a bean vermicelli equipment, specifically is a rubbing type pea peeling device. BACKGROUND

[0002] In the process of the vigorous development of bean vermicelli industry, as one of the core raw materials, the peeling operation in the pretreatment stage of pea is crucial. The epidermis of pea is rich in various components, among which the fiber material will form a physical barrier during starch extraction, hindering the effective dissolution of starch molecules, resulting in a decrease in starch yield; the presence of impurities not only interferes with the purity of starch, but also may cause chemical reactions in subsequent processing, affecting the quality stability of bean vermicelli; and the pigment will make the color of bean vermicelli dark and uneven, seriously weakening the market competitiveness of the product. Therefore, efficient and accurate peeling of peas is the key to obtaining high-quality bean vermicelli.

[0003] The Chinese utility model patent with publication number CN 216363609U discloses a pea peeling and separating device, which realizes pea rubbing and peeling by the rotating movement of the peeling roller in the machine cylinder, thereby improving the peeling efficiency to a certain extent. However, there are still some defects: since the gap between the peeling roller and the machine cylinder is set as a fixed value, when facing the significant difference in the size of pea particles, the device cannot flexibly adjust the size and range of the peeling force. In actual production, when dealing with smaller pea particles, the gap cannot be reduced, and the extrusion force of the peeling roller and the machine cylinder on the peas is relatively large, resulting in damage to the pea petals and destruction of the starch structure, which not only reduces the starch extraction rate, but also may cause small particles produced by the broken pea petals to mix into the starch, affecting the purity and quality of the starch. When facing larger pea particles, the fixed larger gap cannot ensure that the peeling roller is in full contact with the surface of the peas, so that the pea epidermis is not completely removed, and the residual epidermis continues to have a negative impact in the subsequent starch processing link, such as causing uneven starch gelatinization, breaking during the bean vermicelli forming process, etc., ultimately leading to difficulty in ensuring product consistency, seriously restricting the scale production and product quality improvement of bean vermicelli production enterprises, and becoming a key technical problem that needs to be broken through in the industry. UTILITY MODEL CONTENTS

[0004] In view of the above defects or one of the defects in the prior art, the utility model discloses a rubbing type pea peeling device, and the technical scheme adopted is:

[0005] A rubbing type pea peeling device, which includes a machine cylinder and a peeling roller located in the machine cylinder. Unlike the prior art, a plurality of flexible rubbing sheets are uniformly fixed on the roller body of the peeling roller in the circumferential direction by rivets and pressure strips. Under the action of centrifugal force, the flexible rubbing sheets abut against the inner wall of the machine cylinder with peas in between.

[0006] Further, a plurality of ribs are evenly arranged on the inner wall of the barrel abutting the flexible kneading sheet.

[0007] Further, the ribs gradually protrude from the top to the bottom of the inner wall of the barrel.

[0008] Further, the peeling roller and the upper section of the barrel corresponding to the peeling roller are in the shape of a circular truncated cone with the upper section smaller than the lower section.

[0009] Further, a collecting hopper is fixed below the peeling roller in the barrel, the upper edge of the collecting hopper is close to but does not contact the lower end of the peeling roller, and the lower end of the collecting hopper is connected to a bean skin output pipe penetrating through the barrel.

[0010] Further, the outer end of the bean skin output pipe is connected to a cyclone separator, the lower part of the cyclone separator is provided with a bean skin outlet, and the upper part is connected to a bag dust collector and an air suction machine.

[0011] Further, the barrel below the collecting hopper gradually narrows to form a bean paste outlet.

[0012] Further, the upper end surface of the roller body of the peeling roller is in the shape of a circular cone, which is suitable for the scattered peas to fall into the gap between the barrel and the peeling roller.

[0013] Further, the roller body of the peeling roller is a hollow shell-shaped body, the roller shaft is fixed to the upper and lower ends of the roller body and extends upward through the gap penetrating the barrel, the upper part of the barrel is fixed with a roller shaft fixing seat, the upper part of the roller shaft fixing seat is fixed with a motor and a hopper, the roller shaft is connected to the output shaft of the motor through a spline, and the roller shaft is connected to the roller shaft fixing seat through two groups of two back-to-back conical roller bearings.

[0014] Further, the roller shaft and the roller shaft fixing seat are sealed by a rubber sealing ring.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] It has better adaptability in processing different size pea particles. When encountering smaller particle peas, the characteristic that the flexible kneading sheet abuts against the inner wall of the barrel under the action of centrifugal force makes it impossible to generate excessive extrusion force due to fixed gap during the peeling process, effectively avoiding damage to the pea petals and destruction of the starch structure, thereby ensuring the starch extraction rate and purity; for larger particle peas, the flexible kneading sheet can better adhere to the surface of the pea, ensuring more thorough peeling and reducing the adverse effects of skin residues on subsequent starch processing links, improving product consistency, helping the vermicelli production enterprise to realize large-scale production and product quality improvement, and effectively solving a series of problems caused by the fixed gap between the peeling roller and the barrel in the prior art. Compared with simple rubbing of the peeling roller and the barrel, the setting of the flexible kneading sheet increases the contact area and friction force with the peas, further improving the peeling efficiency and quality, and providing more reliable protection for obtaining high-quality pea raw materials required for high-quality vermicelli.

[0026] like Figures 1-6 As shown, a pea peeling device includes a barrel 1 and a peeling roller 2 located inside the barrel 1. The peeling roller 2 and the upper section of the barrel 1 corresponding to the peeling roller 2 are truncated cone-shaped, with the upper section smaller than the lower section. Multiple flexible rubbing blades 23 are evenly fixed along the circumferential direction of the roller body 20 of the peeling roller 2 by rivets 21 and pressure strips 22. Under the action of centrifugal force, the flexible rubbing blades 23 abut against the inner wall of the barrel 1, separating the peas. Multiple ribs 11 are evenly arranged on the inner wall of the barrel 1 where the peas abut against the flexible rubbing blades 23, and the ribs 11 gradually protrude from the inner wall of the barrel 1 from top to bottom. A collecting hopper 3 is fixed inside the barrel 1, below the peeling roller 2. The upper edge of the collecting hopper 3 is close to but does not contact the lower end of the peeling roller 2, and does not exceed the circumferential outer edge of the peeling roller 2. The lower end of the collecting hopper 3 is connected to a sealed pea peel output pipe 4 that extends out of the barrel 1. The outer end of the bean curd skin output pipe 4 is connected to a cyclone separator. The lower part of the cyclone separator has a bean curd skin outlet, and the upper part is connected to a bag filter and an exhaust fan. The machine cylinder 1 below the collection hopper 3 gradually narrows to form a bean curd skin outlet 12. The upper end face of the peeling roller 20 is conical, which is suitable for the pea raw material to fall into the gap between the machine cylinder 1 and the peeling roller 2. The roller body 20 of the peeling roller 2 is a hollow shell. The roller shaft 24 is fixed to the upper and lower ends of the roller body 20 and extends upward through the gap to pass through the machine cylinder 1. The roller shaft fixing seat 5 is fixed above the machine cylinder 1. The motor 6 and the hopper 7 are fixed above the roller shaft fixing seat 5. The roller shaft 24 is connected to the output shaft of the motor 6 through a spline. The roller shaft 24 and the roller shaft fixing seat 5 are rotated through two sets of two back-to-back tapered roller bearings 8. The roller shaft 24 and the roller shaft fixing seat 5 are sealed by a rubber sealing ring 9.

[0027] In the production process of vermicelli, the pea raw material usually needs to go through a specific pretreatment process to better adapt to the subsequent peeling and processing procedures. For the pea raw material used in the device, the appropriate pretreatment method is acid slurry soaking.

[0028] The acid slurry soaked pea has many advantages. First, the acidic components in the acid slurry can moderately corrode the pea epidermis, making the epidermal structure loose, and more easily falling off under the rubbing action of the subsequent peeling device, thereby effectively improving the peeling efficiency and effect. Second, after soaking in acid slurry, the internal organization of the pea absorbs some water and becomes relatively soft, which can reduce the probability of damage to the bean due to mechanical external force during the peeling process, helping to maintain the integrity of the pea bean, thereby ensuring the starch extraction rate and quality. In addition, microorganisms and enzymes and other substances contained in the acid slurry may trigger some biochemical reactions during the soaking process, further decomposing some impurities and pigments in the pea epidermis, not only reducing the adverse effects of epidermal residues on subsequent processing, but also making the extracted starch whiter and purer in quality, laying a good foundation for producing high-quality vermicelli.

[0029] In actual operation, the peas are soaked in an appropriate amount of acid slurry solution, and the soaking time can be reasonably adjusted according to factors such as pea variety, acid slurry concentration, and environmental temperature, to ensure that the peas fully absorb the acid slurry components and the epidermis reaches an appropriate treatment state before being fed into the pea peeling device for peeling treatment.

[0030] After the motor 6 is started, the spline drives the roller shaft 24 to rotate, and then the peeling roller 2 rotates at high speed in the cylinder 1. The pea raw material falls from the hopper 7 into the gap between the cylinder 1 and the peeling roller 2, and under the action of the centrifugal force generated by the rotation of the peeling roller 2, the flexible rubbing sheet 23 abuts against the pea and the inner wall of the cylinder 1, and at the same time, the ribs 11 on the inner wall of the cylinder 1 also play a role in assisting the rubbing of the pea, so that the pea epidermis falls off during the rubbing process. The peeled peas fall into the collecting hopper 3 under the action of gravity, and the collecting hopper 3 collects the peeled peas and makes them discharge from the bean outlet 12; while the bean skin falls off and enters the bean skin output pipe 4 through the collecting hopper 3, and then is separated by the cyclone separator, and the bean skin is discharged from the lower bean skin outlet, and the bag dust collector and air extractor connected to the upper part of the cyclone separator can further process the dust and other impurities generated during the separation process.

[0031] The pea peeling device of the present embodiment has the following excellent technical effects:

[0032] 1. Good adaptability and high efficiency of peeling: the upper section of the peeling roller 2 and the machine cylinder 1 is a circular truncated cone with small upper and large lower, and the peeling roller 2 is provided with a flexible kneading sheet 23, which can adapt to different sizes of pea particles. When processing peas of different sizes, the flexible kneading sheet 23 can adjust the contact force and manner according to the shape and size of the pea particles, compared with the traditional fixed gap peeling device, which avoids the adverse effects of improper gap on the pea petals and peeling effect, and improves the peeling efficiency and quality.

[0033] 2. Effective separation and environmental protection treatment: the setting of the collection hopper 3, the bean skin output pipe 4 and the cyclone separator and other structures realizes the effective separation of the peeled peas and bean skins, and the cyclone separator cooperates with the bag dust collector and the air suction machine to treat the dust and other matters in the bean skin discharge process, reduces environmental pollution and ensures the cleanliness of the working environment.

[0034] 3. Stable support and sealing guarantee: the roller shaft 24 and the roller shaft fixed seat 5 are connected through 2 groups of back-to-back conical roller bearings 8, each group has 2, which can not only bear larger radial load, but also effectively cope with axial force, ensuring the stability of the peeling roller 2 during high-speed rotation; the rubber sealing ring 9 between the roller shaft 24 and the roller shaft fixed seat 5 can prevent dust, impurities and other matters from entering the bearing part, prolong the service life of the equipment and ensure the stable operation of the equipment.

[0035] The above only describes the preferred embodiments of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
