Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of filtering equipment, in particular to a kind of fruit juice beverage processing filter residue device. BACKGROUND

[0002] Fruit juice drink is a kind of common drink, its production process is a comprehensive process, covering multiple links from raw material selection to finished product packaging, generally including raw material preparation (cleaning, peeling and pitting), chopping and juicing, filtering and clarification, blending, homogenization and degassing, sterilization, filling. In the filtering and clarification process, filtering equipment will be used to filter the fiber and solid residue in fruit and vegetable juice. Common filter screens include nylon bag filter screens and stainless steel wire filter screens. As the filtering time increases, the residual filter residue on the filter screen will accumulate more and more, so the water permeability of the filter screen will gradually decrease. Therefore, to avoid the filter screen being clogged by filter residue too quickly, the existing filtering process is divided into multiple filtering steps, i.e., multiple layers of filter screens are provided, and the mesh size of the filter screens increases successively. This effectively increases the filtering time of each filter screen. However, this also requires regular replacement of the multi-sided filter screen of the filtering equipment, and the equipment needs to be temporarily stopped during replacement. Therefore, it has a certain impact on production efficiency. SUMMARY

[0003] The utility model provides a kind of fruit juice beverage processing filter residue device;Solve the problem that the filter screen needs to be replaced regularly in the fruit juice beverage production filtering process in prior art, which affects production efficiency.

[0005] The utility model generally needs to be installed in dustless workshop, avoids the dust in air to cause the pollution to fruit juice. The utility model discloses the filtering principle is: the fresh squeezed fruit juice of waiting for filtering flows into the filter cylinder in the feed pipe, the motor is reduced after the decelerator deceleration, drives the filter cylinder slow uniform speed rotation, the annular filter screen in the filter cylinder is used for filtering, and filtrate flows into the filtrate collection tank below along gravity. Since the annular filter screen is in the rotating state, therefore the filter residue on the annular filter screen will rotate synchronously, and the scraper on the filter residue removal mechanism is attached with the upper inner wall of the annular filter screen, therefore the filter residue attached on the annular filter screen will be scraped by the scraper, and the filter residue on the scraper will fall into the filter residue flow guide groove below under the action of gravity after accumulating to a certain degree, and the filter residue flow guide groove is inclined, therefore these filter residues will flow to the outside along the filter residue flow guide groove, and the utility model discloses the annular filter screen has self-cleaning effect, has the advantage that long time does not need to replace or clean the filter screen, and the use is more convenient.

[0006] Further, the filter residue removal mechanism further comprises a flow guide tile for preventing overflow, which is fixed to the upper side of the filter residue flow guide groove, is arranged on the upper half side of the opening, has a semicircular conical surface structure, and has an outer arc surface upward. The vertical projection of the flow guide tile covers the width of the filter residue flow guide groove. During the rotation of the filter cylinder, the fruit juice remaining in the filter cylinder will fall or flow under gravity. The opening is arranged on the outer baffle, and the fruit juice can easily overflow from the opening to the outside, which can pollute the equipment. Therefore, the flow guide tile is arranged on the upper half side of the opening to guide the fruit juice dripping from the opening to flow back into the filter cylinder, so as to keep the equipment clean.

[0007] Further, a vertical T-shaped sliding groove is arranged on the second fixing seat, the root of the mounting arm is in sliding fit with the T-shaped sliding groove, a screw rod is vertically fixed to the root of the mounting arm upward, an end cover is fixed to the upper end of the second fixing seat, the screw rod penetrates through the end cover, and an adjusting nut is arranged on the upper side of the end cover and is screwed on the screw rod. In this way, the overall height of the mounting arm can be finely adjusted by rotating the adjusting nut, so as to finely adjust the height of the scraper and adjust the effect of scraping the filter residue.

[0008] Further, the scraper is made of flexible silica gel material, and only needs to ensure that the scraper is in abutment with the annular filter screen at a certain angle during installation, and the scraper as a whole needs to be deformed. In this way, the scraper can be completely in abutment with the annular filter screen, and the assembly difficulty between the scraper and the annular filter screen is reduced.

[0009] Therefore, the utility model has the following characteristics compared with prior art: 1. The annular filter screen of the utility model has rotation effect, and the scraper on the filter residue removing mechanism is attached to the upper inner wall of the annular filter screen, so that the filter residue attached to the annular filter screen is scraped off by the scraper and collected by the filter residue flow guide groove, so that the annular filter screen in the utility model has self-cleaning effect, and has the advantage of long-time non-stop replacement or cleaning of filter screen; 2. The utility model sets up flow guide tile on the upper half of the opening to guide the juice dripping from the opening to flow back into the filtering drum, so as to keep the equipment clean.

[0018] See Figure 1 And Figure 3 The filter residue removal mechanism further includes a flow guide tile 470 fixed to the upper side of the filter residue flow guide groove to prevent overflow, the flow guide tile is arranged on the upper half side of the opening, has a semicircular conical surface structure, the outer arc surface faces upward, and the vertical projection of the flow guide tile covers the width of the filter residue flow guide groove. During the rotation of the filter drum, the juice remaining in the inside of the filter drum falls or flows under the action of gravity, the opening is arranged on the outer baffle, and the juice easily overflows from the opening to the outside, which pollutes the equipment. Therefore, the flow guide tile is arranged on the upper half side of the opening in the embodiment to guide the juice dripping from the opening to flow back into the filter drum, so as to keep the equipment clean.

[0019] See Figure 4 The second fixing base is provided with a vertical T-shaped sliding groove 411, the root of the mounting arm is in sliding fit with the T-shaped sliding groove, the root of the mounting arm is vertically fixed upward with a screw rod 421, the upper end of the second fixing base is fixed with an end cover 412, the screw rod penetrates through the end cover, and the upper side of the end cover is further provided with an adjusting nut 422 which is screwed on the screw rod. In this way, the overall height of the mounting arm can be finely adjusted by rotating the adjusting nut, and the height of the scraper is adjusted, so as to adjust the effect of scraping the filter residue.

[0020] See Figure 1 The end of the feeding pipe is provided with a shunt pipe 210, and the bottom of the shunt pipe is uniformly provided with a plurality of shunt holes 211.

[0021] See Figure 1 The lower end of the filter residue guide groove is provided with a filter residue collecting groove 480 for temporarily collecting filter residue, so that the filter residue can be conveniently collected and treated.

[0022] The scraper is made of flexible silica gel sheet material, and only needs to ensure that the scraper is in abutment with the annular filter screen at a certain oblique angle during installation, and the scraper needs to be deformed. In this way, the scraper can be completely in abutment with the annular filter screen, and the assembly difficulty between the scraper and the annular filter screen is reduced.
