[0002] Konjac is an important agricultural economic crop, rich in konjac glucomannan, with good health function and broad application prospect.In the processing of konjac, konjac material has high moisture content and high viscosity, which needs to be transported and preliminarily dehydrated.Currently, the transportation of konjac material mainly relies on manual handling or simple belt conveyor, which not only has high labor intensity and low efficiency, but also easily causes material loss and quality decline.Some existing mechanical conveying devices such as screw conveyor and vibrating conveyor can realize automatic conveying, but for konjac material with high viscosity, they are prone to blockage or material adhesion on the conveying parts, resulting in frequent equipment downtime and cleaning, affecting production efficiency.Meanwhile, these devices often cannot realize the dual functions of material conveying and preliminary dehydration, increasing processing procedures and energy consumption.Therefore, it is urgent to develop a high-efficiency, stable and adaptable conveying device specially for the characteristics of konjac material to improve the automation level and production efficiency of konjac processing.

[0003] In summary, the existing konjac material conveying device has the technical problems of uneven extrusion, easy adhesion of material on the surface of conveying parts, low conveying efficiency and high energy consumption, resulting in high material loss, poor dehydration effect and low production efficiency in the processing of konjac.

[0010] The beneficial effects of the above improvement scheme are: by setting a plurality of grooves on the surface of the first extruding roller and corresponding protrusions on the surface of the second extruding roller, and making them mesh with each other during rotation, the extrusion effect on the konjak material is significantly enhanced. This structural design not only increases the contact area of the material, but also generates shear force on the konjak material during meshing, which promotes water analysis, prevents the material from sliding during extrusion, and ensures the continuity and stability of conveying.

[0011] Further, the material guide plate is made of stainless steel material, and the upper surface of the material guide plate has a plurality of parallel guide ribs, which are arranged along the material flow direction, for guiding the konjac material to smoothly enter the extrusion channel.

[0012] Further, the material guide plate is connected with the conveying frame body through a support rod, one end of the support rod is connected with the conveying frame body through a hinge, for adjusting the inclination angle of the material guide plate.

[0013] The beneficial effects of the above improvement scheme are: the material guide plate is made of stainless steel material and the guide ribs are arranged on the surface, which effectively guides the konjac material to smoothly enter the extrusion channel. At the same time, through the design of the support rod and the hinge connection, the inclination angle of the material guide plate can be adjusted, which is suitable for konjac materials with different flowability, prevents material accumulation or too fast sliding, ensures the uniformity and continuity of material conveying, and improves the working efficiency of the whole device.

[0014] Further, the outlet end of the extrusion channel is provided with a material receiving device, which includes a material receiving hopper and a chute; the material receiving hopper is fixed at the lower part of the conveying frame body, and the bottom of the material receiving hopper is connected with the chute, and the chute and the material receiving hopper form a continuous downward sliding channel for receiving and conveying the konjac material after extrusion treatment.

[0017] The beneficial effects of the above improvement scheme are: by arranging four height-adjustable support feet at the bottom of the base, the installation problem of the device on uneven ground is solved. The support feet adopt the structure of external threaded rod and locking nut, which can independently adjust the height of each support point, ensure that the whole device maintains a horizontal state, avoid uneven distribution of materials and uneven extrusion caused by inclination, and also reduce the vibration of the equipment during operation, prolong the service life of the equipment.

[0018] Further, the diameter ratio of the first extrusion roller and the second extrusion roller is 3:2, the diameter of the first extrusion roller is larger than that of the second extrusion roller, for increasing the extrusion area and extrusion intensity of the konjac material.

[0019] The beneficial effect of the above improvement scheme is that by designing the diameter ratio of the first extrusion roller and the second extrusion roller as 3:2, the diameter of the first extrusion roller is larger than that of the second extrusion roller, which increases the extrusion area and extrusion intensity of the konjac material. This diameter difference design makes the material subjected to uneven linear speed when passing through the extrusion area, generating additional shear force and friction, which is beneficial to destroy the cell structure of the konjac material, promote water analysis, improve dehydration effect and conveying efficiency.

[0020] Further, the cross section of the groove is a V-shaped structure, the opening angle of the V-shaped structure is 60 degrees to 90 degrees, the cross section of the protrusion is a triangular structure matching the V-shaped structure, and the gap between the groove and the protrusion is 0.5mm to 2mm.

[0022] Further, the surface of the first extrusion roller and the second extrusion roller is coated with an anti-sticking layer made of food-grade polytetrafluoroethylene material, and the thickness of the anti-sticking layer is 0.3mm to 0.8mm.

[0023] The beneficial effect of the above improvement scheme is that by coating the first extrusion roller and the second extrusion roller with a food-grade polytetrafluoroethylene anti-sticking layer, the problem of konjac material adhering to the roller surface is effectively solved. This anti-sticking design not only ensures food safety, but also reduces material loss during conveying, avoids frequent cleaning and maintenance of the roller surface due to material adhesion, improves the continuous working capacity and production efficiency of the equipment, and prolongs the service life of the extrusion roller.

[0024] Further, the number of grooves is 8 to 12, the grooves are equally distributed along the circumferential direction on the surface of the first extrusion roller, the number of protrusions is the same as that of the grooves, and the protrusions are equally distributed along the circumferential direction on the surface of the second extrusion roller.

[0025] The beneficial effects of the improved scheme are: by designing the number of grooves and protrusions to be 8-12 and equidistantly distributing them on the surface of the extrusion roller in the circumferential direction, the multi-point uniform extrusion of the konjac material is realized. This distribution design makes the extrusion force uniformly act on the material, avoids the situation of local excessive extrusion or insufficient extrusion, improves the uniformity and consistency of the material processing, and also makes the stress of the extrusion roller more balanced, reduces the wear and energy consumption of the equipment.

[0026] Compared with the prior art, the beneficial effects of the double-roller extrusion type konjac material conveying device provided by the utility model are: the double-roller extrusion type konjac material conveying device of the utility model solves the problems existing in the prior art by optimizing the structural design and material selection.
