Description

Technical Field

[0001] The invention relates to the technical field of vinegar koji purification and fermentation equipment, and in particular to vinegar koji quantitative purification, refining and fermentation equipment and a method. Background Art

[0002] With the continuous development of the food industry, the requirements for quality control and product purity in the food processing process are becoming increasingly stringent, especially in the traditional brewing field, such as the production of vinegar koji. The effective removal of solid impurities in the fermentation liquid has always been a key challenge to improving product quality. The common vinegar koji quantitative purification and refining fermentation equipment on the market is often difficult to completely separate solid impurities when processing the fermentation liquid. This problem directly affects the purification effect of the fermentation liquid, and then affects the taste and quality of the final product. Therefore, we propose a vinegar koji quantitative purification and refining fermentation equipment and method.

[0003] The prior art also has the following defects during use:

[0004] The prior art equipment for quantitative purification, refining and fermentation of vinegar koji usually relies on traditional filtering methods, such as screen filtration or precipitation methods, but these methods are inefficient in removing tiny particles and are prone to clogging, resulting in slow filtration speed and even frequent shutdowns for cleaning. These methods often fail to completely remove soluble solids or colloidal particles, thereby affecting the purity of the fermentation liquid and the taste and safety of subsequent products. The presence of solid impurities has a significant negative impact on the quality of the fermentation liquid. Solid impurities can serve as carriers of microbial contamination, increasing the risk of contamination during the fermentation process, which not only affects the flavor of the product, but may also lead to food safety issues. Secondly, the presence of impurities will reduce the fermentation efficiency, because solid impurities occupy the space of the liquid medium, reducing the opportunity for microorganisms to contact nutrients. In addition, solid impurities will also affect the appearance and texture of the product.

[0005] In view of this, we propose a vinegar koji quantitative purification, refining and fermentation equipment and method to solve the existing problems. Summary of the invention

The separation cylinder 403 can provide a mounting position for the surrounding components, and the separation cylinder 403 is driven to rotate by the motor 304, and the centrifugal force is used to promote the fermentation liquid to be separated and thrown out from the side of the separation cylinder 403, thereby efficiently separating the fermentation liquid from the solid impurities, and ensuring the purification effect of the fermentation liquid.

Under normal conditions, a thrust is applied to the permeable membrane 407 in the direction of the center of the separation cylinder 403. In the separation process, when the permeable membrane 407 is subjected to the centrifugal force and the thrust applied by the fermentation liquid, the corrugated permeable membrane 407 is unfolded in a direction deviating from the center of the circle, thereby expanding the contact area between the permeable membrane 407 and the fermentation liquid and improving the separation efficiency of the fermentation liquid. When the separation cylinder 403 stops rotating, the support frame 408 applies a thrust toward the center of the circle to the permeable membrane 407, so that the permeable membrane 407 is unfolded toward the inside of the separation cylinder 403, and the solid impurities attached to the inside of the permeable membrane 407 are peeled off, so that the solid impurities fall into the separation cylinder 403 for centralized treatment.It also avoids the situation where solid impurities adhere to the surface of the permeable membrane 407 and cause the permeable membrane 407 to be blocked, thereby ensuring the subsequent separation effect of the permeable membrane 407 on the fermentation liquid, enabling the device to efficiently and continuously purify the fermentation liquid, reducing the frequency of device shutdown maintenance, and improving the overall working efficiency of the device.

The support seat 303 can support the separation box 3 to ensure the installation stability of the separation box 3 and its top components.

[0053] Furthermore, a method for using a vinegar koji quantitative purification, refining and fermentation device is provided, and the steps are as follows:

[0054] In the first step, the processed raw materials and fermentation liquid enter the separation box 3 through the discharge valve 102 and are injected into the interior of the separation cylinder 403. The motor 304 is powered on to rotate and drives the separation cylinder 403 and its surrounding components to rotate. Under the influence of centrifugal force, the fermentation liquid passes through the plurality of discharge holes 404 and enters the interior of the card slot 406.

[0055] In the second step, the fermentation liquid passes through the permeable membrane 407 and then is discharged from the separation cylinder 403, guided downward by the inner wall of the heat-conducting cylinder 306, and is discharged through the discharge valve 302 at the bottom of the separation box 3;

[0056] In the third step, after centrifugal separation, the solid residue adheres to the inner side of the permeable membrane 407. After the permeable membrane 407 loses the thrust exerted by the fermentation liquid, it returns to its original state under the influence of the elastic force exerted by the support frame 408, so that the solid residue attached to the inner side is peeled off, and the solid residue is concentrated inside the separation cylinder 403 for centralized treatment, thereby completing the quantitative purification, refining and fermentation of the vinegar koji.

[0057] Working principle: After the device is inspected and confirmed to be correct, the discharge valve 102 is closed, and the raw materials are put into the tank body 1 from the opening on the top of the tank body 1, and the sealing cover 104 is closed to keep the inside of the tank body 1 sealed. Air is supplied to the inside of the tank body 1 and exhaust gas is discharged through the ventilator and the exhaust pipe to promote the fermentation of the raw materials inside the tank body 1 to form fermentation liquid and solid impurities. After the drive motor 604 is powered on, it rotates to drive the drive shaft 6 and the mounting plate 603 to rotate, so that the stirring paddle 601 is suspended in the fermentation liquid near the liquid surface and rotates to stir the fermentation liquid. The fermented fermentation liquid and solid impurities enter the interior of the separation box 3 through the discharge valve 102, and then enter the separation cylinder 403;

[0058] When the separation assembly 4 starts to separate the fermentation liquid, the motor 304 is powered on to rotate and the separation cylinder 403 is driven to rotate at a high speed. The fermentation liquid enters the card slot 406 by centrifugal force, and then is separated by the permeable membrane 407. The pure fermentation liquid is thrown out of the separation cylinder 403 and falls to the bottom of the separation box 3 for collection. The solid impurities are retained in the separation cylinder 403 for centralized treatment. The purified fermentation liquid is taken out of the separation box 3 through the discharge valve 302, and the fermentation and purification of the fermentation liquid are completed.

[0059] When the separation component 4 rotates, the fermentation liquid is affected by the centrifugal force, pushing the permeable membrane 407 to expand in the direction away from the center of the separation cylinder 403, thereby expanding the contact area between the permeable membrane 407 and the fermentation liquid and improving the separation efficiency of the fermentation liquid. When the separation cylinder 403 stops rotating, the support frame 408 applies a thrust toward the center of the separation cylinder 403 to the permeable membrane 407, so that the permeable membrane 407 expands toward the inside of the separation cylinder 403, peeling off the solid impurities attached to the inside of the permeable membrane 407, and causing the solid impurities to fall into the separation cylinder 403 for centralized treatment.

[0060] The above-mentioned specific embodiments are only several preferred embodiments of the present invention.
