Description

Technical Field

[0001] The invention relates to the technical field of fruit and vegetable pressing, and in particular to a fruit and vegetable belt pressing device. Background Art

[0002] In the food processing industry, the production of fruit and vegetable juice is an important field. In order to improve the yield and quality of fruit and vegetable juice, efficient pressing equipment is needed to fully extract the juice from fruits and vegetables.

[0003] The belt press is gradually developed on the basis of traditional pressing technology. Early fruit and vegetable pressing mainly relied on simple mechanical squeezing or manual operation, which was inefficient and labor-intensive. With the continuous advancement of industrial technology, in order to meet the needs of large-scale fruit and vegetable processing, the belt press came into being. It draws on the principle of belt conveyor, through two endless filter belts wrapped around a series of rollers arranged in sequence and of different sizes, and uses the squeezing and shearing action between the filter belts to squeeze fruits and vegetables.

[0004] At present, due to the limited tensile capacity of the filter cloth, the material is squeezed under insufficient pressure, resulting in unsatisfactory squeezing and dehydration effects, and a large amount of liquid remains in the material. For example, in some fruit and vegetable processing with high dehydration requirements, production requirements cannot be met, affecting product quality and subsequent processing. At the same time, it is difficult for easy-flowing slurry to enter the equipment for squeezing. For some fruit and vegetable materials with high water content and strong fluidity, pretreatment is required before use, which increases the complexity and cost of production.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Summary of the invention

[0006] In view of the problems in the related art, the purpose of the present invention is to provide a fruit and vegetable belt pressing device to overcome the above-mentioned technical problems existing in the existing related art.

[0007] The technical solution of the present invention is achieved in this way:

[0008] A fruit and vegetable belt pressing device comprises: a frame, wherein an upper pressing wheel group and a lower pressing wheel group are respectively provided in the frame, and a pressing roller and a limiting roller are provided between the upper pressing wheel group and the lower pressing wheel group, wherein;

[0009] The upper pressing wheel group, the pressing roller and the limiting roller sleeve are provided with an upper filter press belt, and the lower pressing wheel group, the pressing roller and the limiting roller sleeve are provided with a lower filter press belt. The upper filter press belt and the lower filter press belt are located between the pressing rollers to form an extrusion chamber. A transmission shaft is provided in the upper filter press belt, and the transmission shaft is fixedly connected to a driving motor arranged on one side of the frame. A transmission gear is provided at the end of the transmission shaft. A linkage shaft is provided in the lower filter press belt, and a linkage gear is provided at the end of the linkage shaft. The transmission gear is meshed with the linkage gear, and a first material tray is provided at the bottom end of the pressing roller.

[0011] Furthermore, the third roller is movably connected to the frame, and the third roller is used to adjust the tightness of the upper filter press belt.

[0012] Furthermore, the lower pressure wheel group includes: a first material roller, a support wheel group and a second material roller, and the lower pressure filter belt is sequentially wound around the first material roller, the pressure roller, the limiting roller, the upper and lower material wheel groups, the transmission shaft, the linkage shaft, the support wheel group and the second material roller.

[0013] Furthermore, the first material roller is movably connected to the frame, and the first material roller is used to adjust the tightness of the lower filter belt.

[0014] Furthermore, a feeding platform is provided on one side of the frame, and the feeding platform is located at the top of the lower filter belt.

[0015] Furthermore, the transmission shaft and the linkage shaft are respectively located on one side of the frame, the transmission shaft is located at the top end of the linkage shaft, and the frame is provided with a blanking plate on one side of the transmission shaft.

[0016] Furthermore, the frame is provided with a second material tray at the bottom end of the first material tray.

[0017] Beneficial effects of the present invention:

[0018] The present invention conveys fruits and vegetables to the feeding platform through a conveyor belt, and a driving motor drives a transmission shaft to cooperate with a transmission gear and a linkage gear to drive the linkage shaft to rotate, so that the fruits and vegetables in the feeding platform are conveyed inward through the lower filter belt and the upper filter belt, and squeezed by a pressure roller and a limiting roller, so that the fruit and vegetable juice flows into the first material tray, and the waste residue is squeezed again by the upper and lower material wheel group after passing through the limiting roller, and the liquid flows into the first material tray, and the remaining material is discharged through the lower plate on one side of the upper and lower material wheel group. Not only can the water be removed quickly, but also a large amount of water in the fruits and vegetables can be squeezed out quickly by using the pressure of the upper and lower filter belts. For fruits such as apples, grapes, etc., and vegetables such as carrots, cabbage, etc., their water content can be effectively reduced, so as to prepare for subsequent processing such as making preserved fruits, dehydrated vegetables, etc. At the same time, the squeezing stability is improved, and the squeezing effect is good through multiple squeezing, and the fruits and vegetables can be fully squeezed, and the liquid content remaining in the fruits and vegetables is small.

A first material tray 14 is provided at the bottom of the pressing roller 4.

[0032] In addition, the upper pressing wheel group 2 includes: a first roller 21, a second roller 22, a third roller 23, a fourth roller 24 and an upper and lower material wheel group 25. The upper filter belt 6 is wound around the first roller 21, the second roller 22, the third roller 23, the fourth roller 24, the pressing roller 4, the limiting roller 5, the upper and lower material wheel group 25 and the transmission shaft 9 in sequence.

[0033] The third roller 23 is movably connected to the frame 1 , and the third roller 23 is used to adjust the tightness of the upper filter press belt 6 .

[0034] In this technical solution, the upper filter press belt 6 is sequentially wound through the first roller 21, the second roller 22, the third roller 23, the fourth roller 24, the pressure roller 4, the limit roller 5, the upper and lower material wheel group 25 and the transmission shaft 9, and the drive motor 10 drives the transmission shaft 9, so that the upper filter press belt 6 is transported to the side of the pressure roller 4 through the first roller 21, and cooperates with the pressure roller 4 to squeeze the fruits and vegetables.

[0035] At the same time, the movable connection of the third roller 23 facilitates the position adjustment of the third roller 23 , thereby adjusting the tightness of the upper filter press belt 6 .

[0036] In addition, the lower pressing wheel group 3 includes: a first material roller 31, a supporting wheel group 32 and a second material roller 33.
