Description

Technical Field

[0001] The invention relates to the technical field of microbial fermentation, and in particular to a tank-type kimchi fermentation water recycling treatment device and a recycling method. Background Art

[0002] Sichuan pickles are vegetable products made from fresh vegetables, which are salted and fermented with lactic acid bacteria. They taste salty and sour, and are crisp, refreshing, appetizing and refreshing. The fermentation process of Sichuan pickles is mainly carried out under the dominance of lactic acid bacteria, but because yeasts such as Pichia membrane-fungus and Saccharomyces cerevisiae are inevitably attached to the raw materials, the presence of these yeasts has a negative effect, such as causing pickle biochemistry and producing unpleasant sour and smelly odors, which seriously affects the quality of pickles, causing the quality of pickles to deteriorate, and a large number of products to be discarded, causing serious economic losses to pickle production companies. Secondly, the carefully maintained pickle water has an excellent flavor, is rich in pectin, dietary fiber, etc., and is rich in nutrients, but these good pickle waters are generally treated as wastewater in industrial production. First of all, the pickle water contains a large number of microorganisms, and direct discharge will cause water pollution to a certain extent, and the salt content in the pickle water is relatively high. Secondly, direct discharge will lead to waste of water resources, etc. Summary of the invention

[0003] The present invention provides a tank-type fermented kimchi water recycling treatment device and recycling method to solve the above-mentioned deficiencies of the prior art, can recycle and reuse the kimchi water, and reduce environmental pollution and waste of production materials caused by direct discharge of the kimchi water.

[0004] In order to achieve the purpose of the present invention, the following technologies are proposed: On the one hand, a tank-type fermented kimchi water recycling treatment device is proposed, including a treatment tank, which is connected to an ultrasonic sterilizer through a pipeline. After high-frequency ultrasonic treatment, the microorganisms therein die due to the cavitation effect of the ultrasonic wave causing the cell membrane of the yeast to be perforated. The ultrasonic sterilizer is connected to an ultraviolet sterilizer through a pipeline, and the ultraviolet sterilizer is connected to a temporary storage tank through a pipeline. The treatment tank is used for filtering and settling operations of kimchi water, the ultrasonic sterilizer and the ultraviolet sterilizer are used for sterilizing kimchi water, and the storage tank is used for storing kimchi water. The treatment device can filter the larger vegetables remaining in the kimchi water through the treatment tank, and further treat the solids remaining in the kimchi water by static sedimentation. The two filtering methods reduce the content of solids in the kimchi water, thereby avoiding the impact on the quality of kimchi when the kimchi water is reused. The ultrasonic sterilizer and the ultraviolet sterilizer can effectively kill the miscellaneous bacteria such as yeast in the kimchi, thereby avoiding the impact of yeast on the quality of kimchi when it is reused. The above device basically solves the adverse effects caused by the discharge of kimchi water.

[0005] The processing tank includes a middle tank body, and a plurality of mounting parts are welded on the outer wall of the middle tank body, and supporting legs are welded on the mounting parts. The lower end of the middle tank body is connected to a liquid outlet pipe, and the liquid outlet pipe is arranged at the lower end. Firstly, it is convenient to discharge all the supernatant liquid, thereby increasing the recyclable amount of the treated kimchi water, and secondly, it can avoid the impurity content in the kimchi water during discharge, thereby improving the quality of the kimchi water during reuse. A transparent plate is arranged on the middle tank body, and the transparent plate is convenient for the operator to observe the clarity of the supernatant liquid, so as to reasonably control the timing of supernatant liquid discharge.

[0006] Considering that kimchi water contains a large amount of leaves and rhizomes of some vegetables that are difficult to remove when it is reused, and these have a common feature that they are large in size. If conventional filtering components such as the common disc filtering components on the market are used, these substances are likely to cause clogging of the filtering components, resulting in reduced filtering capacity and filtering efficiency. In addition, it is inconvenient to clean such solids, which further reduces the filtering capacity. Based on existing or common filtering components, this solution hereby installs a filter tank at the upper end of the middle tank body through bolts, and an installation ring is installed at the upper end of the filter tank through bolts. A conical ring is provided on the inner periphery of the installation ring, and the lower end of the conical ring is a small end. A plurality of holes are provided on the conical ring. The lower end of the conical ring is open, and the diameter of the upper end of the conical ring is larger than the diameter of the lower end of the conical ring. The lower end of the conical ring is formed with an upturned edge, and the cross section of the upturned edge is an L-shaped structure. A conical bucket is placed on the upturned edge, and the lower end of the conical bucket is a small end. The conical bucket is opened. A filtering hole is provided, and a placing ring is provided at the upper end of the conical bucket. The outer circumference of the placing ring is a conical structure, and the outer circumference of the placing ring is in contact with the inner circumference of the conical ring, and the upward edge is passed through the placing ring. A connecting rod is provided at the lower end of the conical bucket, and a buckle cover is provided at the upper end of the connecting rod. A lower extending ring is provided on the lower wall of the buckle cover, and a connecting protruding rod is provided at the upper end of the buckle cover. A pull ring is provided on the connecting protruding rod. The conical bucket plays a filtering role. Secondly, in the filtering process, due to the limitations of the conical ring and the conical bucket structure, solids are gathered in the conical bucket. After gathering for a period of time, they can be removed through the pull ring, thereby achieving the purpose of conveniently handling the filtered material.

[0007] An end ring is installed on the upper end of the filter tank by bolts, and the end ring is located above the installation ring. The lower extension ring is inserted into the end ring, and the buckle cover is placed on the end ring. An annular part is installed on the end ring by bolts, and the annular part is connected with a liquid inlet pipe. A feed hole is provided on the end ring and directly below the annular part, and a guide cone ring is provided on the lower wall of the end ring. The opening size of the lower end of the guide cone ring is larger than the opening size of the upper end, and the guide cone ring is located directly below the feed hole. The arrangement of the buckle cover and the lower extension ring can prevent impurities from entering the filter tank, and the arranged guide cone ring can make the kimchi water flow downward from the inner periphery of the conical ring, thereby improving the filtration efficiency and effect.

[0008] Taking into account that the kimchi water in the lower tank body is likely to become turbid when the supernatant or sediment is discharged, and then when the supernatant is extracted, the impurity content in the kimchi water will increase, thereby affecting the quality of the kimchi, a lower tank body is installed at the lower end of the middle tank body by bolts, and a plurality of lugs are welded on the outer periphery of the lower tank body, and a pair of sealing seats are symmetrically provided on the outer periphery of the lower tank body, and a rotating shaft is rotatably provided on the sealing seat, and a mounting plate is welded between the rotating shafts, and an inner disk is mounted on the mounting plate by screws, and the inner disk is located inside the lower tank body, and one of the rotating shafts is connected to a servo motor, and the servo motor is installed on the sealing seat, and a sealing ring is provided on the outer periphery of the inner disk, and a lower convex ring is formed on the lower wall of the inner disk, and the outer periphery of the lower convex ring is a conical structure, and the lower end of the outer periphery of the lower convex ring is a small end, through the inner disk, when it is in a vertical state, the solids in the kimchi water will settle downward. When the kimchi water or sediment is discharged, the inner plate is adjusted to a horizontal posture. In this posture, when the supernatant is discharged, the sediment can be prevented from being drawn out due to extraction and other reasons, thereby affecting the quality of the kimchi water. By separating the kimchi water backward, the sediment can be prevented from contaminating the supernatant.

[0009] In order to improve the sealing effect of the inner disk, an inner ring is welded on the inner periphery of the lower tank body, and a plurality of vertical rods are passed through the inner ring. A limit nut is provided at the lower end of the vertical rod, and the limit nut is located below the inner ring. A sealing ring is provided at the upper end of the vertical rod. An embedded ring groove is provided on the upper wall of the sealing ring. The outer peripheral side of the embedded ring groove is a conical structure. A sealing rubber ring is provided on the outer periphery of the sealing ring. The outer periphery of the sealing rubber ring abuts against the inner periphery of the lower tank body. A spring is sleeved on the vertical rod. The spring is located between the sealing ring and the inner ring. When the sealing ring seals the inner disk, the lower convex ring is passed through the embedded ring groove. When the inner disk rotates, the sealing ring will rotate downward due to the pushing effect of the inner disk. When the inner disk is in a horizontal posture, the inner disk and the lower tank body can be further sealed by the sealing ring, thereby improving the separation and sealing effect.

[0010] Considering the problem that the sediment after sedimentation is inconvenient to discharge, and it is easy to cause pollution to the supernatant during discharge, an inner extension ring is welded on the lower wall of the inner ring, and an outer convex edge is formed at the lower end of the outer periphery of the lower tank body, and a sealing ring groove is provided on the lower wall of the outer convex edge, and the outer periphery of the sealing ring groove is a conical structure. A sedimentation lower tank is provided at the lower end of the lower tank body, and the lower end of the sedimentation lower tank is an arc-shaped structure. A pair of rotating shafts are symmetrically provided on the outer periphery of the sedimentation lower tank, and a sealing inner ring is provided on the inner periphery of the upper end of the sedimentation lower tank. The lower end of the inner extension ring abuts against the upper end of the sealing inner ring. A sealing end ring is formed on the upper end face of the sedimentation lower tank, and a sealing convex ring is formed on the upper wall of the sealing end ring. The sealing convex ring is inserted into the sealing ring groove. The above structural design improves the sealing effect of the lower tank body and the sedimentation lower tank.

[0011] The rotating shaft sleeve is provided with a lower extension arm, a rectangular frame is installed on the upper end of the lower extension arm, and lower extension rods are installed at the four corners of the rectangular frame. The lower end of the lower extension rod is sleeved with a sleeve, and a movable base is installed at the lower end of the sleeve. A plurality of universal wheels are installed at the lower end of the movable base. The universal wheels are used to facilitate the transfer of sediment. In order to enable the sedimentation tank to be lifted and lowered, the lower extension rods and sleeves are sleeved together.

[0012] A pair of connecting horizontal plates are welded to the upper end of the sleeve, and waist-shaped holes are opened on the connecting horizontal plates. A moving rod is passed through the waist-shaped holes, and a moving plate is provided on the moving rod. A limiting plug rod is welded to the lower end of the moving plate, and the limiting plug rod is passed through the sleeve and the lower extension rod. The problem of the limiting plug rod being pulled out and left behind can be avoided by connecting the horizontal plates, and the limiting plug rod is passed through the sleeve and the lower extension rod to lock the limiting plug rod and the sleeve.

[0013] The cam is secured to the bottom of the turret and has a nut on its outer end for locking the turret in place when the turret is in a locked position.

[0014] In order to lock the state of the lower tank during the sedimentation process, and to improve the sealing effect between the lower tank and the lower end of the lower tank body, a rotating connecting plate is hinged on the lug through a hinge shaft, a concave piece is welded on the other end of the rotating connecting plate, a lower extending convex plate is welded on the lower end of the concave piece, a connecting shaft is provided at the lower end of the lower extending convex plate, an end nut is provided at the outer end of the connecting shaft, a rotating top plate is rotatably provided on the connecting shaft, the end nut is located on the outer side of the rotating top plate, a handle rod is provided at the lower end of the rotating top plate, an upper push rod is rotatably provided at the upper end of the rotating top plate, an outer end of the upper push rod is provided with an outer nut, the outer nut is located on the outer side of the rotating top plate, and the concave piece is sleeved on the rectangular frame. The outer periphery of the upper push rod acts on the lower wall of the rectangular frame, and a concave plug rod is inserted on the outer side of the concave piece, and the concave plug rod is located on the outer side of the rectangular frame. The concave plug rod not only limits the concave member, but also constrains the rotation of the rotating top plate. The setting of the rotating top plate can make the sedimentation lower tank move upward when it rotates, thereby improving the sealing effect between the sedimentation lower tank and the lower tank body.

[0015] The ultraviolet sterilizer comprises an outer shell, a plurality of ultraviolet lamp tubes are arranged inside the outer shell, a quartz tube is arranged inside the outer shell, and the quartz tube is in a spiral structure. The spiral structure prolongs the killing effect of ultraviolet light on yeast.

[0016] A stirrer is arranged in the temporary storage tank, and a plurality of feeding ports are opened at the upper end thereof, and a liquid discharge pipe is connected to the lower end of the temporary storage tank.

[0017] On the other hand, a method for recycling tank-type fermented kimchi water is proposed, which uses a tank-type fermented kimchi water recycling treatment device to treat and reuse the tank-type fermented kimchi water, including the steps of: Step 1, pre-treatment of kimchi water, passing the collected kimchi water into a filter tank in the processing tank to filter out impurities through the filter tank, and letting the kimchi water entering the middle tank body, the lower tank body and the sedimentation tank stand for more than 1 hour; Step 2, separation of kimchi water and sediment, starting the servo motor to separate the sediment from the supernatant through the inner plate, and continuing the sedimentation for more than one hour; Step 3, processing the kimchi water, pumping out the supernatant through a peristaltic pump, passing through an ultrasonic sterilizer and an ultraviolet sterilizer in sequence during the pumping, so as to sterilize the supernatant through the ultrasonic sterilizer and the ultraviolet sterilizer, and pumping the obtained supernatant into a temporary storage tank for standby use; Step 4, treatment of the precipitate, after the supernatant is extracted, the connection between the settling lower tank and the lower tank body is disconnected, and the obtained precipitate is transferred to the precipitate stacking place; Step 5, preparation of kimchi water, injecting sterile alkali solution into the temporary storage tank, and stirring the kimchi water with an agitator at a speed of rpm to make the pH value of the kimchi water in the temporary storage tank between .-.; Step 6, fermentation of vegetables, pump the kimchi water in the temporary storage tank into the vegetable fermentation tank, and when injecting, prepare the kimchi water according to the volume ratio of kimchi water to water: the salinity of the prepared kimchi water used for fermentation is .%, and put the pickled vegetables and auxiliary materials in turn to ferment the vegetables at a temperature of ℃.

[0018] The advantages of the above technical solution are: The present invention can realize the reuse of kimchi mother water.

[0049] The tank-type fermented kimchi water recycling treatment device proposed in this embodiment undergoes the following steps when treating kimchi water: Step a, recovering the kimchi water removed from the vegetables, wherein the kimchi water contains a large amount of kimchi residues and solid impurities.

[0050] Step b, the recovered kimchi water enters the annular member 106 through the liquid inlet pipe 107, and flows downward along the upper end of the conical ring 108 through the feed hole and under the guidance of the guide cone ring 111. During the flow, part of the kimchi water will flow downward through the holes to the middle tank body 100 and the parts below, and part of the kimchi water will also enter the middle tank body 100 and the parts below through the filter holes, and the filtered solids with a larger volume will move to the conical bucket 116 under the flushing action of the kimchi water.

[0051] If there are too many impurities to be filtered, the conical bucket 116 is pulled upwards by the pull ring 115, and then the impurities therein are poured into a recovery container. Of course, the injection of kimchi water needs to be stopped during the treatment process. When the solids in the conical bucket are discharged, they are placed on the conical ring 108 again.

[0052] Step c, the kimchi water entering the middle tank body 100 and the parts below will undergo sedimentation for at least 2 hours. During the sedimentation process, it is necessary to ensure that the inner plate 122 is in a vertical posture. During the sedimentation process, the impurities in the kimchi water will be precipitated into the sedimentation lower tank 137. During the sedimentation process, the operator will always monitor the turbidity of the supernatant until the turbidity of the supernatant does not change for a period of time.

[0053] Step d, start the servo motor 121 to make the inner disk 122 in a horizontal position, and after rotation, the spring 133 will act on the sealing ring 127, so that the sealing ring 127 is under the action of the spring 133, and the lower convex ring 125 is inserted into the embedded ring groove 128, so that the inner disk 122 seals the lower tank body 118.

[0054] Step e, and sedimentation is performed again.

When the supernatant passes through the ultrasonic sterilizer 2 and the ultraviolet sterilizer 3, the yeast therein is basically processed.

[0060] Example 4 A method for recycling tank-type fermented kimchi water, comprising the steps of: Step 01, fermentation of vegetables, prepare fermentation water with clean water and kimchi fermentation agent, and add the pickled vegetables and auxiliary materials in turn to ferment the vegetables at a temperature of 25°C.

[0061] The vegetables used in the above-mentioned embodiments 2 to 4 are radishes and the like, and the auxiliary materials used are condiments such as peppers and peppercorns, and the pickled vegetables and auxiliary materials mentioned above vary depending on the specific circumstances, and this type of pickling technology is a conventional technology, so it will not be described in detail here.

[0062] In order to verify whether the ultrasonic sterilizer 2 and the ultraviolet sterilizer 3 can achieve the sterilization effect, the total number of lactic acid bacteria and yeast colonies in the kimchi water before and after sterilization was measured. The results are shown in the following table: Table 1 Changes in the total number of lactic acid bacteria and yeast colonies in kimchi water before and after sterilization CFU / mL before sterilization CFU / mL after sterilization Number of lactic acid bacteria in kimchi water <![CDATA[9.8×10 7 ]]> 0 Yeast count in kimchi water <![CDATA[4.85×10 6 ]]> 11 It can be seen that the number of lactic acid bacteria and yeast in kimchi water can be effectively reduced through sterilization operation.

[0063] Table 2 Lactic acid bacteria, yeast, total acid and bag swelling of kimchi after 2 days of fermentation under different treatments Sensory evaluation results: The kimchi prepared in Example 3 has a good flavor, moderate acidity, and a good overall evaluation. Example 1 is second, and the kimchi in Example 4 has a poor flavor and an unpleasant odor. At the same time, the bag expansion experiment shows that the fermentation of yeast in Example 4 produces gas with a bad odor, which affects the overall flavor of the kimchi. Although yeast is inevitably present on the surface of vegetables, which is inevitable in kimchi production, the overall results show that sterilized kimchi water helps reduce the number of yeasts in kimchi water, shortens the bag expansion time, and improves the flavor of kimchi.

[0064] In order to further verify whether this scheme is applicable to a variety of kimchi, sterilized kimchi water was used as fermentation water and cowpea was used as the fermentation object. The results are as follows: Table 3 Total acid, yeast, lactic acid bacteria, sensory and bag swelling of sterilized kimchi soaked cowpea for 3 days From the comprehensive implementation results, this process can shorten the fermentation time and significantly reduce the number of bad yeasts in kimchi compared with traditional fermentation. It can also prolong the bag swelling time of kimchi, and the kimchi has moderate acidity, good flavor, and good overall quality. At the same time, this method can also make comprehensive use of kimchi water, reduce environmental pollution, save water, and reduce energy consumption.
