Description

Technical Field

[0001] This utility model relates to the field of pear juice production technology, specifically to a juicing device for pear juice production. Background Technology

[0002] In the industrial production of pear juice, belt juicers are widely used due to their strong continuous operation capability and large processing capacity. Their working principle involves using a filter belt to enclose crushed pear pulp, and then separating the juice from the pulp through the progressive compression of multiple layers of pressure rollers. However, existing technologies have the following problems:

[0003] Because pear pulp has thin cell walls, excessive compression can easily cause the pulp to break, allowing a large amount of turbidity, such as cell fragments and pectin, to seep into the juice, reducing clarity and increasing subsequent filtration time. On the other hand, reducing the pressure results in insufficient juice yield and waste of raw materials. Existing equipment lacks a precise pressure gradient control mechanism for pear raw materials, making it difficult to achieve both high extraction rate and low turbidity. At the same time, the high viscosity of pear pomace easily adheres to the filter screen pores, especially in the low-pressure pre-pressing section. Existing equipment mostly uses single-mesh filter belts, which easily cause the filter belts to become clogged. Frequent shutdowns to wash the filter belts severely restrict the efficiency of continuous production. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 , Figure 2As shown, this utility model provides a juicing device for pear juice production, including a base frame 1. A pressing and juicing mechanism 2 and a cleaning mechanism 6 are arranged on the top of the base frame 1. A feeding mechanism 3 is arranged above the cleaning mechanism 6. A slag-cleaning mechanism 4 and a collecting mechanism 5 are arranged on the front side of the base frame 1, with the collecting mechanism 5 located below the slag-cleaning mechanism 4. The pressing and juicing mechanism 2 includes two fixed supports 21 on the left and right sides. An extension plate 22 is fixedly installed on the front side of each of the two fixed supports 21. Three hanging plates 23 are fixedly installed at the bottom end of each of the two extension plates 22. A pressure roller 25 is movably installed between the opposite faces of the two hanging plates 23 on the left and right sides. A servo motor 24 is fixedly installed on the right side of each of the three hanging plates 23 on the right side. The output shafts of the three servo motors 24 pass through the space between the two hanging plates 23 on the left and right sides and are fixedly connected to the right end of the pressure roller 25. A pear juice collecting funnel 11 is fixedly installed on the top of the base frame 1. The collecting funnel 11 is located at the bottom of the three pressure rollers 25. The right side of the pear juice collecting funnel 11 is fixedly connected to a conveying pipe 12 that passes through the bottom of its inner cavity. A silicone plate is fixedly installed on the front side of the fixed bracket 21 below the last pressure roller 25. The feeding mechanism 3 includes two L-shaped brackets 31. A filter belt drive wheel 32 is set between the horizontally opposite faces of the two L-shaped brackets 31. A filter belt is driven on the outer wall of the filter belt drive wheel 32. A drive wheel is set at the top of the opposite faces of the two fixed brackets 21. A pressing filter belt is set on the outer wall of the drive wheel. The pressing filter belt and the filter belt both pass through the bottom of the three pressure rollers 25, and the pressing filter belt is located above the filter belt. The top of the two L-shaped brackets 31 is respectively equipped with a feeding box 33 and a flat roller 34. The feeding box 33 is located behind the flat roller 34. A feeding pipe for dropping pear pieces is fixedly connected through the top of the feeding box 33. The feeding box 33 and the flat roller 34 are both located above the filter belt.

[0025] Pre-treated pear pieces enter the feeding box 33 through the feeding pipe. The spreading roller 34 evenly spreads the pear pieces on the lower filter belt. The filter belt has a low mesh size to ensure the juice permeability. The upper pressing filter belt adopts a high mesh size filter screen design, which can cover the pear pieces and form a sandwich structure to enter the pressing area to prevent the pulp from shifting. The last side pressure roller 25 lightly presses the broken pear pulp at a pressure of 0.2-0.5MPa to release free juice and avoid excessive cell wall rupture that would cause turbidity. The middle pressure roller 25 moderately increases the pressure to 0.8-1.2MPa to extract deep juice. The foremost side pressure roller 25 applies strong pressure of 1.5-2.0MPa to squeeze out the residual juice and improve the juice yield. The squeezed juice penetrates the double-layer filter belt and flows into the pear juice collection funnel 11. The silicone plate behind the last roller scrapes off the residual juice from the filter belt and flows into the conveying pipe 12 for output through the funnel.

[0026] like Figure 3 , Figure 4As shown, the slag cleaning mechanism 4 includes a slag cleaning box 41, which is fixedly installed on the front side of the base frame 1.

A water supply pipe 44 is fixedly connected to the rear side of each water spray box 43, which passes through its inner cavity, and can be connected to an external water supply. The rear ends of the two water spray boxes 43 both pass through the inner cavity of the slag cleaning box 41 and are evenly fixedly connected with several water spray heads 45. A motor-driven cleaning roller 46 is arranged between the left and right sides of the inner wall of the slag cleaning box 41. The two cleaning rollers 46 are respectively located on the two guide rollers. Between 42 and the water spray box 43, two cleaning rollers 46 are fixedly installed on the outer walls of each of the two cleaning rollers 46. The two cleaning rollers 47 are respectively attached to the filter belt and the pressing filter belt. The collection mechanism 5 includes a pear pulp collection box 51. The top opening of the pear pulp collection box 51 is located directly below the cleaning box 41. A filter plate 54 is fixedly installed in the inner cavity of the pear pulp collection box 51.

The pear pulp collection drawer 53 is slidably connected to the pull hole 52. A stainless steel filter plate is fixedly installed at the bottom of the inner ring of the pear pulp collection drawer 53. A sewage pipe 55 is fixedly connected to the lower front side of the pear pulp collection box 51, which passes through the inner cavity below the filter plate 54.

[0027] The pressed residue enters the cleaning box 41 along with the filter belt. The upper and lower guide rollers 42 separate the filter belt from the pressing filter belt. The water spray head 45 washes the filter belt pores with water pressure of 15-20MPa. The brush deeply cleans the blockage. The cleaning roller 46 drives the cleaning brush 47 to rotate at high speed to peel off the adhering pectin. The pear residue falls into the collection mechanism below. The cleaned filter belt returns to the feeding area for recycling. After the pear residue falls into the pear residue collection drawer 53, its bottom stainless steel filter plate can be drained a second time. The residual juice penetrates the filter plate 54 and is discharged through the drain pipe 55. Pull out the pear residue collection drawer 53 to take out the dry residue, which can be used for feed or fertilizer recycling.

[0028] like Figure 5 As shown, the cleaning mechanism 6 includes a vertical plate 61. A servo motor 62 is fixedly installed on the right side of the vertical plate 61. The output shaft of the servo motor 62 passes through to the left side of the vertical plate 61 and a rotating roller 63 is fixedly installed thereon. A brush 64 is fixedly installed on the outer wall of the rotating roller 63. The bottom of the brush 64 is in contact with the surface of the filter belt. A water supply pipe 65 is fixedly installed behind the left side of the vertical plate 61. Several high-pressure nozzles 66 are evenly fixedly connected to the side of the water supply pipe 65 near the rotating roller 63. The right end of the water supply pipe 65 passes through to the right side of the vertical plate 61 and is fixedly connected to an inlet pipe 67. The inlet pipe 67 is connected to a water supply pipe for water supply. A sewage collection box 13 and a debris collection plate 14 are fixedly installed at the bottom of the base frame 1. The sewage collection box 13 is located below the water supply pipe 65 and the rotating roller 63, and the debris collection plate 14 is located below the filter belt.

[0029] After returning, the filter belt can be scraped by the rotating brush 64 included in the cleaning mechanism 6 to remove deep impurities, and the high-pressure nozzle 66 washes it simultaneously. The wastewater flows into the wastewater collection box 13, and the filter belt before reaching the cleaning structure can have residual small debris fall into the debris collection plate 14 for easy cleaning and to effectively ensure continuous production.

[0030] The working principle of this pear juice production juicing equipment will be explained in detail below.

[0031] like Figure 1-5 As shown, the pre-treated pear pieces enter the feeding box 33 through the feeding pipe. The spreading roller 34 evenly spreads the pear pieces on the lower filter belt. The filter belt has a low mesh size to ensure the juice permeability. The upper pressing filter belt uses a high mesh size filter screen design to cover the pear pieces, forming a sandwich structure to enter the pressing zone and prevent the pulp from shifting. The last side pressure roller 25 lightly presses the broken pear pulp at a pressure of 0.2-0.5MPa to release free juice and avoid excessive cell wall rupture leading to turbidity. The middle pressure roller 25 moderately increases the pressure to 0.8-1.2MPa to extract deeper juice. The foremost side pressure roller 25 applies strong pressure of 1.5-2.0MPa to squeeze out the residual juice and improve the juice yield. The extracted juice penetrates the double-layer filter belt and flows into the pear juice collection funnel 11. The silicone plate behind the last roller scrapes off the residual juice from the filter belt and flows into the conveying pipe 12 for output through the funnel. The pressed residue enters the slag cleaning box 41 with the filter belt. Guide roller 42 separates the filter belt from the pressing filter belt. Water spray head 45 rinses the filter belt pores with 15-20MPa water pressure. Brushes deeply clean blockages. Sweeping roller 46 drives the slag cleaning brush 47 to rotate at high speed, peeling off the adhering pectin. Pear pulp falls into the collection mechanism below. The cleaned filter belt returns to the feeding area for recycling. After the pear pulp falls into the pear pulp collection drawer 53, its bottom stainless steel filter plate can be drained a second time. The residual juice penetrates the filter plate 54 and is discharged through the drain pipe 55. Pull out the pear pulp collection drawer 53 to take out the dry pulp, which can be used for feed or fertilizer recycling. The returned filter belt can be scraped by the rotating brush 64 included in the cleaning mechanism 6 to remove deep impurities from the filter belt. High-pressure spray head 66 washes simultaneously. Wastewater flows into the wastewater collection box 13. The filter belt before reaching the cleaning structure allows residual small pieces to fall into the piece collection plate 14 for easy cleaning and effectively ensure continuous production.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
