Description

TECHNICAL FIELD

[0001] The utility model relates to a popcorn processing technical field especially is popcorn quantitative sub -packaging anti -blocking device. BACKGROUND

[0002] The sub -packaging equipment generally comprises an upper hopper and a bottom tapered shrink structure, and the popcorn has physical properties such as light weight, irregular shape, sugar coating or grease coating on the surface, etc., in actual production, when the material is guided to the discharge port through the inclined wall surface of the tapered structure, arch-shaped accumulation is easily formed in the transition area of the cone and the discharge port, leading to material flow interruption or intermittent blockage, this phenomenon is called "arching" or "arch effect".

[0003] The arching problem is mainly caused by the breaking of the mechanical balance in the material flow process. The lateral stress is generated by the mutual extrusion of popcorn particles during the downward process, and the meshing effect between particles and the friction force with the tapered wall gradually increase. Especially at the junction of the lower end of the cone and the discharge port, the sudden reduction of the cross-sectional size aggravates the interlocking jamming of the particles, at this time, the material self-gravity cannot overcome the friction resistance and the shear stress formed between the particles, leading to the change of dynamic flow into static accumulation.

[0004] The existing solutions usually use mechanical vibration to apply external force to destroy the arch structure, or add a rotating lever to stir the material. However, such solutions have obvious defects, mechanical vibration can easily cause popcorn to break, affecting product quality, built-in stirring device increases the complexity of the equipment, and the driving parts directly contact with the material, which may introduce lubricating oil pollution risk, difficult to meet the food-grade hygiene requirements, and the energy consumption is high, long-term operation increases the production cost.

[0005] Some improved solutions alleviate arching by optimizing the geometric parameters of the cone, such as increasing the taper angle to reduce the contact time of the material with the wall, or using a parabolic transition curve to reduce local resistance. However, a too large taper angle will lead to a decrease in the utilization rate of the hopper volume, and the actual processing of the curved structure is difficult to accurately control the curvature of the inner wall, which may instead cause new stagnation points due to sudden changes in local curvature. In addition, there is a scheme of coating low-friction coefficient material on the inner wall of the cone, but the sugar attached to the surface of the popcorn is easy to adhere when the temperature and humidity change, and the coating will gradually weaken its friction reduction effect after long-term use.

[0006] Therefore, the existing technology has not fundamentally solved the arching problem in the tapered sub -packaging structure of popcorn, and an innovative scheme that takes into account the simplicity of the structure, the safety and stability of the operation is urgently needed.

After reaching the rated amount, the first gate valve 3 is closed, and then the second gate valve 4 is opened to let it fall into the dispensing cup below. In this dispensing structure, the cone-shaped converging end at the bottom of the hopper 1 is prone to arching due to its gradually shrinking size. Therefore, an anti-arching device is set at this change point to achieve a better arch-breaking effect.

[0036] In the preferred embodiment, the first electric push rod 5 and the second electric push rod 6 are symmetrically arranged on one side of the first slide valve 3 and the second slide valve 4, respectively.

[0051] The gas flow in each fan-shaped area flows along the surface of the guide plate 15 towards the center of the chamber, and continues to move in the circumferential direction under the influence of rotational flow inertia. The rotational flow is divided into a plurality of fan-shaped areas when it hits the guide plate 15. At the gap at the end of the guide plate 15, a low-pressure area is generated due to the centrifugal effect, accelerating the movement of the gas flow towards the exhaust port. The gas flow enters the converging area around the gas injection pipe 12 from the gap of the guide plate 15, and is finally discharged through the exhaust port.

[0052] The above-mentioned embodiments are only preferred technical solutions of the present application, and should not be regarded as limiting the present application, and the protection scope of the present application should be the technical solutions recited in the claims, including the equivalent replacement solutions of the technical features recited in the claims as the protection scope.
