Embodiment 1

[0037] Such as figure 1As shown, a oozing device provides a oozing device, including a pretreatment system and a leaching device 3 connected by a belt conveyor, and the high-end output port of the leaching device 3 is facing the input of the waste meal water recovery system The outlet of the low end of the exudator is connected with the input port of the exudate juice treatment system; the low end of the exudator is provided with a vegetable feeding bucket 34, and the high end of the exudator is respectively provided with a water inlet 36 and a water inlet 35.

[0038] The pretreatment system includes a shredder 11, a first blancher 12 and a courgette pump (not shown in the figure) which are sequentially connected by a conveyor belt of a belt conveyor.

[0039] The waste meal water recycling system includes a screw conveyor 41, a press machine 42, a curved screen 43, a meal pressing water tank 44 and a third scalding device 14 which are connected successively by the conveyor b...

Embodiment 2

[0047] This embodiment is except following feature, and other is all identical with embodiment 1:

[0048] Four groups of plate-type submerged ultrasonic extraction devices are continuously installed in the middle of the tank bottom (third and fourth sections) in the Dds double-helix chute continuous exfiltration device, and the spacing is equal and evenly distributed to achieve the effect of enhancing the balance of exudation efficiency.

[0049] In this embodiment, the first section and the second section at the lower end of the Dds double-helix chute continuous oozer are heated with exhaust steam, and the air intake mode is air intake from both sides; The third and fourth sections are heated with evaporating three-effect gas. Heat the vegetable-water mixture to the required temperature (about 70°C in the first section of the Dds double-helix chute-type continuous oozer, and about 50°C in the end section of the Dds double-helix chute-type continuous oozer), ultrasonic freque...

Embodiment 3

[0051] This embodiment is except following feature, and other is all identical with embodiment 1:

[0052] Five groups of plate-type submerged ultrasonic extraction devices are continuously installed in the middle of the tank bottom (third and fourth sections) of the Dds double-helix chute continuous exfiltration device, and the spacing is equal and evenly distributed to achieve the effect of enhancing the balance of exudation efficiency.

[0053] In this embodiment, the first section and the second section at the lower end of the Dds double-helix chute continuous oozer are heated with exhaust steam, and the air intake mode is air intake from both sides; The third and fourth sections are heated with evaporating three-effect gas. Heat the vegetable-water mixture to the required temperature (about 70°C in the first section of the Dds double-helix chute-type continuous oozer, and about 50°C in the end section of the Dds double-helix chute-type continuous oozer), ultrasonic freque...

Abstract

The invention discloses a low-frequency high-energy ultrasonic-coupled fluidized beet-exudating method and device. Three or more large-amplitude ultrasound transducers are assembled into a group and sealed inside a box body to manufacture a plate-type immersed ultrasonic extracting device, wherein the plate-type immersed ultrasonic extracting device resonates at the same frequency to form a single-sided radiator so as to achieve a quick and efficient exudating process. The method and the device can shorten the exudating time and reduce the water consumption and the workload of an evaporating working section, thus reducing the coal consumption and the steam consumption and achieving aims of saving energy, protecting environment and improving the production efficiency.

Description

technical field [0001] The invention relates to the technical field of beet sugar production, in particular to a low-frequency high-energy ultrasonic coupling fluidized exudation method and device for beets. Background technique [0002] The exudation process is one of the most important processes in the beet sugar production process: the beet shredded cells are fully broken, and then fully contacted and mixed with high-temperature water or dilute sugar juice, and the sucrose in the beet is divided into Extract as much as possible, and leave non-sugar as much as possible in the waste cabbage to obtain high-purity leaching juice. [0003] In the above process, the main factors affecting the exudation efficiency are: the quality of shredded vegetables, exudation temperature, exudation time, juice extraction rate, exudation water, microorganisms, uniformity of exudation operation, etc. At present, the national sugar beet sugar industry generally adopts continuous leaching devi...
