Description

Technical Field

[0001] The invention relates to the technical field of fruit juice impurity removal, and in particular to a fruit juice impurity removal device. Background Art

[0002] To make juice, you need to first clean the fruit, remove the skin and core, cut the fruit, crush, squeeze and filter the fruit, and then adjust water or sugar and other condiments in the juice according to the needs of the product formula. Finally, sterilize and package it. When the fruit is crushed and squeezed, the pulp will be broken. After the juice in the pulp is squeezed out, the peel fragments, protein, pectin, cellulose and other debris in the pulp will be mixed in the juice, making the juice turbid and affecting the taste of the juice, so the impurities in the juice need to be filtered.

[0003] In the existing juice removal, a juice vibrating screen is mostly used for vibrating and filtering the juice. A plurality of screens are arranged on the juice vibrating screen. The juice passes through a plurality of screens with successively increasing precisions in turn to filter out impurities in the juice. At the same time, under the vibration of the vibrating screen, the impurities move on the screen along the inner wall of the vibrating screen and are automatically discharged at the discharge port, so that continuous filtering can be performed. However, when dealing with different juices, due to the different fruit raw materials or different preparation processes, the amount of impurities of various sizes in the juice will be different. When the juice vibrating screen vibrates, the vibration amplitudes of different layers of the screens are different, so that when filtering different types of juices, the impurities in the juice may be blocked at a certain layer of the screen. Therefore, in order to adjust the vibration amplitudes of different layers on the vibrating screen when filtering different types of juices and perform targeted vibration screening of the juice, we propose a juice impurity removal device.

[0014] The working principle and beneficial effects of the present invention are:

[0015] 1. In the present invention, by setting an adjustment plate 1 and an adjustment plate 2, and by adjusting the position of the connection plate 1, the vibration amplitudes of multiple screens can be made different. When the connection member 1 is set on the upper part of the adjustment plate 1, the vibration amplitude of the screen close to the motor is higher. When the connection member 1 is set at the lower part of the adjustment plate 1, the vibration amplitude of the screen far away from the motor is higher. Due to the different pass rates of the screens in each layer, residues of different sizes can be targetedly screened and filtered with greater intensity. When adjusting the connection member 1, since the base cannot contact the base, otherwise it will cause the base to collide with the base when vibrating. The height of the base can be adjusted by adjusting the position height of the connection member 2 on the adjustment plate 2 to avoid contact between the base and the base. At the same time, by adjusting the position of the screw rod 1 fixed on the strip groove, the sliding stretching distance of the pull rod in the sliding frame can be adjusted, and the degree of extrusion of the spring can be adjusted at the same time. When the screw rod 1 is fixed at a position far away from the connection member 2, the distance that the pull rod extends out of the sliding frame is longer, and the distance between the connection member 1 and the connection member 2 is longer. When the base vibrates, the spring can buffer the sliding of the pull rod in the sliding frame;

[0016] 2. In the present invention, by providing an annular track and a scraping brush, after the residual material baffle rotates, the scraping brush is vibrated on the screen frame and can rotate together with the impurities on the screen on the annular track. The scraping brush scrapes the impurities on the screen surface while moving along the annular track, and then the residual material baffle rotates in the opposite direction and contacts the screen through the reversal of gear 2. When the scraping brush rotates one circle and drives the impurities to the discharge frame, the scraping brush contacts the residual material baffle and stops moving.

[0017] 3. In the present invention, by setting a lifting connection mechanism, the vibration amplitude of different positions of the multi-layer screen can be controlled by adjusting the connection position with the adjustment plate, so as to carry out targeted vibration screening of different juices. By setting a cleaning mechanism, the scraping brush can automatically rotate under the action of vibration through the vibration of the screen frame itself to clean the surface of the screen, thereby reducing the use of mechanical devices, lowering maintenance costs and failure rates.
