Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable beverage processing technology, and in particular to a homogenizing and anti-oxidation mixing tank for high dietary fiber fruit and vegetable pulp. Background Technology

[0002] High-fiber fruit and vegetable juice is a beverage made by processing vegetables and fruits rich in dietary fiber. Its core feature is the retention or enhancement of natural dietary fiber content. It uses high-fiber fruits and vegetables such as apples, pears, carrots, celery, citrus fruits, and dragon fruit as raw materials. Through processes such as crushing and homogenization, it retains water-soluble fiber (such as pectin) and insoluble fiber (such as cellulose) in the pulp and pulp. Some products may have additional functional fibers (such as inulin). The pulp needs to be homogenized and stirred during the processing of fruit and vegetable juice.

[0003] Compared with existing technologies, the existing fruit and vegetable pulp homogenizing mixing tanks rely solely on sealing or vacuum treatment to prevent oxidation. However, vacuum can easily cause the pulp bubbles to expand, affecting the homogenization effect. Negative pressure can also damage the physical state of the pulp, affecting the homogenization quality of the fruit and vegetable pulp. Furthermore, most existing fruit and vegetable pulp mixing tanks use single-speed mixing, which can easily lead to fiber stratification or excessive shearing, damaging the structure and affecting the processing quality of fruit and vegetable juice. Therefore, we propose a high-dietary-fiber fruit and vegetable pulp homogenizing and anti-oxidation mixing tank to solve the above problems. Utility Model Content

[0032] Specifically, the second stirring mechanism includes a servo motor B310, which is fixed to the bottom of the mounting tank 100 by bolts. The output end of the servo motor B310 is provided with a drive shaft B320, and the output end of the drive shaft B320 is provided with a stirring blade B330.

[0037] Working Principle: During use, the operation of the mixing tank is controlled by the control panel 120. Fruit and vegetable pulp is injected into the installation tank 100 through the feed pipe 131. The servo motor A210 drives the drive shaft A220 to rotate at high speed, which in turn drives the mixing blades A230 to rotate. The mixing blades A230 perform high-speed shearing of the fruit and vegetable pulp, instantly breaking down the fiber clumps and achieving homogenization. The servo motor B310 drives the drive shaft B320 to rotate at low speed, which in turn drives multiple mixing blades B330 to rotate. The mixing blades B330 propel the broken fruit and vegetable pulp in a circulating manner, preventing fiber sedimentation and avoiding mixing blind spots. The air inlet 430 connects to external inert gas, which enters the jet vent 450 through the inflation pipe 440 and... Inert gas is released into the installation tank 100 through the jet trough 450. The inert gas concentration inside the inflation pipe 440 is monitored in real time by the inert gas concentration detector 470, and the start and stop of the external inert gas supply device are controlled. This reduces the oxygen content inside the installation tank 100, reduces the risk of oxidation of the fruit and vegetable pulp, and avoids the damage to the physical state of the fruit and vegetable pulp caused by negative pressure. The inert gas released into the installation tank 100 gathers at the top of the installation tank 100 and enters the installation box 520 through the connecting groove 530. The inert gas is filtered by the filter block 540 and then enters the collection box 420 through the exhaust pipe 550, realizing the recycling of inert gas and reducing the consumption of inert gas during anti-oxidation operations. When the discharge operation is required, the control valve 620 is opened, and the fruit and vegetable pulp is discharged through the installation pipe 610 and the discharge pipe 630.
