Description

Technical Field

[0001] This invention relates to the field of food pickling technology, and in particular to a rapid fermentation device. Background Technology

[0002] Pickling vegetables is a time-honored method of vegetable processing. Due to its simplicity, low cost, ease of preservation, and unique color, aroma, and flavor that cannot be replaced by other processed products, pickled vegetables are very popular with consumers. The fermentation process for pickled vegetables is generally dominated by lactic acid fermentation, accompanied by small amounts of alcoholic fermentation and trace amounts of acetic acid fermentation.

[0003] Currently, in the process of pickling and fermenting vegetables, the vegetables are first coated with a prepared sauce, then placed in a fermentation device and sealed, and finally pickled and fermented at a certain temperature for a certain period of time to obtain pickled vegetables with unique flavor.

[0004] To improve fermentation efficiency, existing fermentation devices often pack a large quantity of vegetables at once. During prolonged static fermentation, the fermentation liquid tends to separate into layers, with higher concentrations at the bottom and lower concentrations at the top. This results in differences in flavor between the two layers, affecting the overall taste. Furthermore, the tightly packed vegetables hinder the even distribution of the fermentation liquid, further reducing the stability of the pickled vegetable's flavor during fermentation. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art by proposing a rapid fermentation device to improve the taste stability of pickled and fermented vegetables.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A rapid fermentation apparatus, comprising: Box; A cover plate, which is located on the top of the box; Multiple water outlet pipes are evenly distributed at the bottom of the cover plate, and each water outlet pipe has multiple water outlet holes on its side wall. Each water outlet pipe can be inserted into the upper layer of vegetables. A return pipe is installed on the cover plate, and one end of the return pipe is connected to each outlet pipe; The circulation pipe is located at the bottom of the box. The circulating pump has its suction port connected to the circulating pipe and its discharge port connected to the return pipe to draw juice from the bottom of the tank and deliver it to each outlet pipe. The heating element is horizontally positioned at the bottom of the cover plate and is connected to the return pipe.

[0008] Furthermore, the heating mechanism includes a sealing head and a heating rod. One end of the heating tube extends to the outside of the cover plate, and the sealing head is located at the end of the heating tube located outside the cover plate. The heating rod is located on one side of the sealing head, and a power cord is provided on the other side of the sealing head. The power cord is connected to the heating rod.

[0009] Furthermore, a protective net is provided on one side of the sealing head, the protective net is located outside the heating rod, and a temperature sensor is provided inside the protective net.

[0010] Furthermore, the heating tube is equipped with a filter screen inside. The filter screen is cylindrical and fits against the inner wall of the heating tube.

[0011] Furthermore, a sealing ring is provided at the bottom of the cover plate, and a fixing plate is fixedly connected to the bottom of the sealing ring, with the lower surface of the sealing ring fitting against the edge of the fixing plate.

[0023] Reference Figure 1-5 A rapid fermentation device is used for pickling and fermenting vegetables to improve the stability of the pickled flavor.

[0024] The rapid fermentation device includes a box 1, a cover plate 7, a reflux pipe 8, a circulation pipe 9, and a circulation pump; The bottom of the box 1 is equipped with a filter plate 3. One end of the circulation pipe 9 is connected to the bottom of the box 1 and communicates with the bottom of the filter plate 3. One end of the return pipe 8 is connected to the bottom space of the cover plate 7. The suction port of the circulation pump is connected to the circulation pipe 9 and the discharge port is connected to the return pipe 8.

[0025] During fermentation, vegetables to be fermented are first placed inside the container 1, with a layer of pickling ingredients containing probiotics sprinkled on each layer of vegetables. Once the container 1 is full, the cover 7 is placed on top. The device is then pushed into the fermentation chamber, and the temperature is adjusted to maintain it at 38℃±2℃ to ensure effective probiotic fermentation. During fermentation, a circulation pump is connected to the circulation pipe 9 and the return pipe 8. The circulation pump extracts the fermentation juice from the bottom of the container 1 and transports it to the top of the container 1 through the return pipe 8, allowing the juice to flow through each layer of vegetables again, ensuring thorough mixing of the probiotics and vegetables, and guaranteeing the effective fermentation.

[0026] In some embodiments, the filter plate 3 is provided with a plurality of filter holes spaced apart. The filter holes can filter the juice and prevent vegetable scraps in the juice from entering the circulation pipe 9 and causing blockage of the return channel.

[0027] It should be noted that the filter plate 3 is at a certain distance from the bottom inner wall of the box 1 to ensure the circulation of fermentation juice.

[0028] It also includes a fixing plate 6, which is located below the cover plate 7. Multiple water outlet pipes 5 are arranged at intervals on the bottom of the fixing plate 6, and multiple water outlet holes 501 are arranged at intervals on the side wall of each water outlet pipe 5.

[0029] After the cover plate 7 is placed on top, the fixing plate 6 is pressed down on the vegetables, and each water outlet pipe 5 is inserted into the vegetables. At this time, when the circulation pump is used for circulation, the fermentation juice comes to the fixing plate 6 through the return pipe 8, and then enters each water outlet pipe 5. It then enters the vegetables evenly through the water outlet holes 501 on each water outlet pipe 5, thereby further mixing the probiotics with the vegetables and improving the probiotic fermentation effect.

[0030] In some embodiments, each water outlet pipe 5 is arranged vertically and has a conical bottom to facilitate its insertion into the vegetables and allow the fermentation juice to enter the upper layers of vegetables.

[0031] In some embodiments, a sealing ring 701 is provided at the bottom of the cover plate 7, and a fixing plate 6 is fixedly connected to the bottom of the sealing ring 701. The lower surface of the sealing ring 701 is in contact with the edge of the fixing plate 6 to ensure that the juice output from the return pipe 8 enters each water outlet pipe 5 through the fixing plate 6 and avoids overflow.

[0032] In some embodiments, a heating tube 11 is also included. The heating tube 11 is arranged horizontally at the bottom of the cover plate 7 and is connected to the return pipe 8. The heating tube 11 is provided with a heating mechanism inside and a water outlet 1101 is provided at the bottom.

[0033] The juice in the reflux pipe 8 enters the heating pipe 11, where it is heated by the heating mechanism. It is then discharged through the outlet 1101 and finally flows through the fixing plate 6 into each outlet pipe 5. The juice is heated by the heating mechanism, ensuring that the fermentation temperature inside the chamber 1 is consistently maintained at 38℃±2℃. Compared to existing methods of maintaining the fermentation temperature of the chamber 1 with external heating, this rapid fermentation device more accurately controls the fermentation temperature inside the chamber 1, improving the fermentation effect.

[0034] In some embodiments, a filter screen 13 is provided inside the heating tube 11. The filter screen 13 is cylindrical and fits against the inner wall of the heating tube 11. Juice will pass through the filter screen at the outlet 1101 and be discharged, thereby preventing juice from clogging the outlet hole 501 of the outlet tube 5.

[0035] It should be noted that the top of the filter screen 13 is provided with a round opening that is compatible with the return pipe 8, so that juice can easily enter the interior of the cylindrical filter screen 13 through the return pipe 8.

[0036] In some embodiments, the heating mechanism includes a sealing head 12 and a heating rod 14. One end of the heating tube 11 extends to the outside of the cover plate 7, and the sealing head 12 is disposed at the end of the heating tube 11 located outside the cover plate 7. The heating rod 14 is disposed on one side of the sealing head 12, and a power cord 1401 is provided on the other side of the sealing head 12. The power cord 1401 is connected to the heating rod 14.

[0037] The heating rod 14 can be inserted horizontally into the heating tube 11 through the sealing head 12 to heat the inside of the heating tube 11. The sealing head 12 can also be removed to facilitate the inspection and replacement of the heating rod 14. In addition, removing the sealing head 12 also makes it convenient to disassemble, clean and replace the filter screen 13.

[0038] In some embodiments, a protective net 1201 is provided on one side of the sealing head 12. The protective net 1201 is located outside the heating rod 14, thereby protecting the heating rod 14 and preventing debris from the juice from adhering to the surface of the heating rod 14.

[0039] In some embodiments, a temperature sensor is provided inside the protective net 1201 to detect the temperature of the juice during fermentation.

[0040] In some embodiments, the top of the housing 1 is provided with a sealing groove 2, which is U-shaped, and a water outlet pipe 201 and a water inlet pipe 202 are provided on the sealing groove 2.

[0041] Water can be injected into the sealed groove 2 through the water injection pipe 202. After the cover plate 7 is put on, the four edges of the cover plate 7 can be inserted into the sealed groove 2, thereby sealing the inside of the box 1. The water inside the sealed groove 2 can be released through the water drain pipe 201, making it convenient to take out the vegetables after fermentation.

[0042] In some embodiments, a protrusion is provided on one side of the sealing groove 2, and the upper end of the water injection pipe 202 extends into the interior of the protrusion and is higher than the inner bottom surface of the protrusion of the sealing groove 2.

[0043] Since the upper end of the water injection pipe 202 is higher than the inner bottom surface of the protrusion, water is prevented from flowing out in reverse through the water injection pipe 202 after water is injected into the sealing groove 2. The protrusion also makes it convenient for staff to observe the water injection situation, judge the amount of water injected in time, and avoid overflow.

[0044] In some embodiments, the circulation pipe 9 is provided with a drain outlet 10, through which the juice produced after fermentation can be conveniently discharged.

[0045] In some embodiments, since the vegetables are relatively loose and take up a lot of space when they are placed in layers inside the box 1, in order to improve space utilization and make it easier to pickle more vegetables at once; The rapid fermentation device also includes a pressure plate 4, which is a frame-shaped, hollow structure. When vegetables are placed inside the chamber 1, the pressure plate 4 can be pressed down using external equipment or heavy objects, thereby pressing down layers of vegetables to ensure that there are enough vegetables inside the chamber 1 and improving the fermentation efficiency.

[0046] In some embodiments, a reinforcing rod 101 is provided in the middle of the outer side of the box body 1. The reinforcing rod 101 is square in shape and is welded to the outer wall of the box body 1. It can provide a fastening force to the side wall of the box body 1 and prevent the side wall of the box body 1 from expanding and deforming when the pressure plate 4 presses down the layers of vegetables.

[0047] In some embodiments, the bottom of the housing 1 is provided with a plurality of support rods 102, which can support and fix the bottom wall of the housing 1, thereby improving the stability of the housing 1.

[0048] In some embodiments, the bottom of the box 1 is provided with casters 103, which facilitates pushing the box 1 and thus makes it easy to transport vegetables to different processing lines.

[0049] The working principle of this rapid fermentation device is as follows: Washed vegetables are layered inside the container 1, with a layer of pickling ingredients containing probiotics added after each layer. Once the container 1 is full, a pressure plate 4 is placed on top of the vegetables. External equipment or a heavy object is then used to press down the pressure plate 4, ensuring sufficient vegetables are placed inside the container 1. Next, the cover plate 7 is placed on top, with its four edges inserted into the sealing groove 2. Water is then injected into the sealing groove 2 through the water injection pipe 202, submerging the edges of the cover plate 7 and sealing the inside of the container 1. The sealed container 1 is then pushed into the fermentation chamber, and the temperature is adjusted to maintain 38℃±2℃ to ensure effective probiotic fermentation.

[0050] During the fermentation process, the fermentation juice at the bottom of the chamber 1 is extracted by a circulation pump and transported to the top of the chamber 1 through the return pipe 8. Then it enters each water outlet pipe 5. Since each water outlet pipe 5 is evenly inserted into the upper layers of vegetables, the fermentation juice enters the upper layers of vegetables evenly through the water outlet holes 501 on each water outlet pipe 5, so that the probiotics and vegetables are further mixed, and the probiotic fermentation effect is improved.

[0051] Furthermore, during the fermentation juice reflux process, the juice in the reflux pipe 8 enters the interior of the heating pipe 11, where it is heated by the heating rod 14. It is then discharged through the outlet 1101 and finally flows into each outlet pipe 5 through the fixing plate 6. The juice is heated by the heating rod 14, thus ensuring that the fermentation temperature inside the chamber 1 is consistently maintained at 38℃±2℃. Compared to existing methods of maintaining the fermentation temperature of the chamber 1 through external heating, this rapid fermentation device more accurately controls the fermentation temperature inside the chamber 1, improving the fermentation effect.

[0052] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
