The elastic wear-resistant member 13 is attached to the inner wall of the ice discharge section cylinder 4 and the inner wall of the filter cylinder 5; the screw 6 is a three-head screw 6 The flushing 10 water inlet and the ice water outlet 3 are symmetrically arranged on both sides of the upper part of the washing filter cartridge; the negative pressure section cylinder 15 is a transparent visual cylinder; Isolated from Motor 1.
工作时，经过冷冻结晶后的果汁从洗滤筒的料液进口7进入，电机1带动螺杆6转动，浓缩的液体穿过过滤网筒5被抽液泵抽走，被截留在过滤网筒5内壁上的冰晶较轻，可以顺着螺杆6向上浮，同时螺杆4转动，会对冰晶产生较大的推进力，使得冰晶被螺杆6向上推进，液体出在负压段筒体15，冰晶上浮处于排冰段筒体4，使得液体在负压段筒体15被充分分离，在冰水排出腔14中，大量的冰晶被排冰刀9切碎，冲洗10水从冲洗10水进口被送入，对上部的冰晶冲刷，少量粘附在冰晶上的果汁被冲洗10后，在负压抽吸作用下，液体下行并不断冲刷接触到的冰晶，最后自身浓度提高后成为浓缩果汁，再从过滤网筒5穿过；在冰水排出腔14中，大量的冰晶被融化或从冰水出口3被冲走，在外部换热融化后，重新从冲洗10水进口流入，循环进行冰晶的洗涤，避免了水资源的浪费，同时由于负压段筒体15为透明可视的，能够很清晰当看清楚负压段筒体15的果汁浓缩程度。During operation, the juice after freezing and crystallization enters from the feed liquid inlet 7 of the washing filter cartridge, the motor 1 drives the screw 6 to rotate, and the concentrated liquid passes through the filter mesh cylinder 5 and is pumped away by the suction pump, and is trapped in the filter mesh cylinder 5. The ice crystals on the inner wall are relatively light and can float up along the screw 6. At the same time, the rotation of the screw 4 will generate a greater propulsion force on the ice crystals, so that the ice crystals are pushed upward by the screw 6, and the liquid flows out of the cylinder 15 in the negative pressure section, and the ice crystals float up. In the cylinder body 4 of the ice discharge section, the liquid is fully separated in the cylinder body 15 of the negative pressure section. In the ice water discharge chamber 14, a large number of ice crystals are chopped by the ice discharger 9, and the rinse 10 water is fed from the inlet of the rinse 10 water. , wash the upper ice crystals, after a small amount of juice adhering to the ice crystals is washed for 10, under the action of negative pressure suction, the liquid descends and continuously washes the ice crystals in contact, and finally its concentration increases to become concentrated juice, and then filtered from The mesh cylinder 5 passes through; in the ice water discharge chamber 14, a large number of ice crystals are melted or washed away from the ice water outlet 3. After the external heat exchange is melted, it flows in again from the washing water inlet 10, and the ice crystals are washed in a cycle. The waste of water resources is avoided, and at the same time, since the cylinder body 15 of the negative pressure section is transparent and visible, the degree of juice concentration of the cylinder body 15 of the negative pressure section can be clearly seen.
