Description

Technical Field

[0001] The invention relates to the technical field of natural fermentation of prepared dishes, in particular to a device for processing natural fermentation of prepared dishes by microorganisms. Background Art

[0002] Pre-prepared meals, also known as pre-prepared conditioned foods, are high in oil and salt, which is not good for health if eaten for a long time. They generally refer to semi-finished or finished products made from various agricultural, livestock, poultry, and aquatic products as raw materials, with seasonings and other auxiliary materials, and processed through pre-selection, modulation and other processes. Usually, pre-prepared meals need to be stored or transported under cold chain conditions for consumers or processors in the catering industry to simply heat or cook before consumption.

[0003] Fermentation tank refers to the device used for microbial fermentation in industry. Its main body is generally a main cylinder made of stainless steel plate, with a volume ranging from 1m3 to hundreds of m3. In design and processing, attention should be paid to tight and reasonable structure, ability to withstand steam sterilization, certain operational flexibility, minimum internal accessories (avoid dead corners), strong material and energy transfer performance, and certain adjustments for easy cleaning and reduced pollution, suitable for the production of a variety of products and reduced energy consumption.

[0004] In the production and processing of predictable dishes, cutting and fermentation of raw materials are essential processing steps; and in the existing fermentation processing equipment, a motor drives an internal stirring rod to stir and mix the dishes and fermentation liquid during the fermentation process. The dishes in the fermentation liquid are easily destroyed and inconsistent with the expected taste. In addition, manual preparation of side dishes is required during the production after fermentation, and the side dishes cannot be cut while fermenting, resulting in low work efficiency and waste of manpower.

[0005] In order to solve the above technical problems, a person skilled in the art has disclosed a patent for a natural fermentation process of pre-prepared dishes using microorganisms and a processing equipment thereof, and its publication number is: CN117603781 A; its technical solution includes a bottom plate, a pre-prepared dish fermentation mechanism, a rotating material pouring structure, and a prepared dish cutting mechanism. Through the cooperation between the cam and the pad, the cam on its outer surface is driven to rotate while the limit rod rotates. One side of the raised part of the cam was originally tightly attached to the right side of the pad through the force of the push rod. Since the outer surface of the pad is made of elastic rubber material, the pad has good seismic resistance and can reduce the impact and vibration caused by earthquakes or mechanical vibrations. Therefore, when the cam is attached to the pad by the force, the vibration and noise of the fermentation furnace itself are effectively reduced when the drive motor is working, ensuring the stability of the fermentation furnace itself when the knife disc cuts the dishes. After the fermentation furnace rotates, the pad also effectively buffers the fermentation furnace to prevent damage to components caused by excessive gravity of the fermentation furnace.

[0006] However, the following problems still exist in the actual use of the above patents:

[0007] 1. During the implementation of the above patent, the transmission structure between the pre-prepared food fermentation mechanism and the prepared food cutting mechanism is relatively complicated, and the transmission parts are easily damaged during the connection and transmission process, which increases the failure rate of the equipment;

[0008] 2. During the implementation of the above patent, the transmission frequency and transmission strength between the pre-prepared food fermentation mechanism and the prepared food cutting mechanism are both relatively low, and the cutting strength and efficiency of the prepared food cutting mechanism cannot be guaranteed;

[0009] Therefore, those skilled in the art need a pre-prepared food microbial natural fermentation processing equipment that can better ensure the linkage efficiency of fermentation mixing and food preparation and cutting. Summary of the invention

[0049] A natural fermentation process of microorganisms for preparing prepared dishes, comprising the following steps:

[0050] S1. Fermentation preparation: Before the pre-prepared dishes are subjected to natural microbial fermentation, the fresh vegetables to be fermented are first washed, then placed in an oven at a temperature of 45-55° C. to dry until the moisture content is 60-70%, then taken out and cooled to room temperature for later use;

[0051] S2, pour and crush: after the dishes are ready, open the feed cover 22 and pour the dried dishes into the filter screen 24 from the feed port, add the Aspergillus oryzae spore suspension after all are poured in, then turn on the drive motor 27 to make several knife discs 212 cut the dishes, and mix them with the Aspergillus oryzae spore suspension while cutting;

[0052] S3, preparing dishes: when the fermentation liquid and the dish pieces are mixed in the furnace, the servo cylinder 31 drives the push rod 32 to repeatedly extend and retract to drive the fermentation furnace 21 to shake to promote the complete fermentation of the fermentation liquid and the dishes in the furnace, and at the same time, the cam 311 swings and drives the rocker 44 to rotate, so that the cutter in the chassis 46 rotates, and the staff puts the dishes prepared together with the pre-prepared dishes into the feed port 47 for cutting and standby, and waits for the fermentation of the fermentation liquid to be completed before making them;

[0053] S4, fermentation and sterilization: After the dishes are completely crushed and mixed, the heat pipe starts to heat up and use the heat pipe to control the temperature in the furnace at 30-35°C for natural fermentation for 24-36 hours to make a fermentation liquid. After the fermentation liquid is made, the heat pipe is controlled to rise to 120-130°C for 30 minutes to sterilize the fermentation liquid in the furnace;

[0054] S5. Discharging and unloading: After the processing is completed, the fermentation liquid is discharged through the conduit connected to the liquid outlet flange 23 at the bottom. After the fermentation liquid is discharged, the servo cylinder 31 is controlled to drive the top rod 32 to retract, so that the fermentation furnace 21 rotates 180° around the limit rod 39 as the center, so that the feed port faces the bottom plate 1, and after placing a slag receiving box above the bottom plate 1, the feed cover 22 is opened to pour out the vegetable slag inside the filter screen 24, and the water in the furnace is drained and rinsed to clean the fermentation furnace through the pipe connected to the liquid outlet flange 23.

[0055] The working principle of the technical solution of this application is as follows:

[0056] First, before the pre-prepared dishes are fermented, for example, amaranth stems or sauerkraut, the staff first washes the fresh vegetables to be fermented, then places them in an oven at a temperature of 45-55° C. and dries them to a water content of 60-70%, takes them out and cools them to room temperature, opens the feed cover 22, pours the dishes from the feed port into the filter screen 24, and adds an appropriate amount of Aspergillus oryzae spore suspension at the same time. Aspergillus oryzae is a common fungus that is widely used in fermentation and food industries, such as making products such as soy sauce, monosodium glutamate and yogurt. Aspergillus oryzae spore suspension is usually obtained by culturing Aspergillus oryzae spores. This suspension contains a large amount of Aspergillus oryzae spores and can be used in the fermentation process in the food industry. Aspergillus oryzae spore suspension can be added to food raw materials. Amaranth stems, sauerkraut and other foods are fermented by microorganisms, which not only increases the taste and flavor of the food, It also improves the nutritional value and increases the content of vitamins and probiotics. After the feeding is completed, the feed cover 22 is closed and the drive motor 27 is turned on. The drive motor 27 drives the rotating shaft 210 to rotate through the transmission shaft 28. When the rotating shaft 210 rotates, the vegetables are minced through a number of knife discs arranged on its outer surface and the vegetables are completely mixed with the Aspergillus oryzae spore suspension. Since the servo cylinder 31 is arranged below the fermentation furnace 21 and is affected by gravity, a bearing 29 is arranged for connection. The shaft seal 29 can prevent liquid or gas from flowing out or entering the gap between the transmission shaft 28 and the equipment, which helps to maintain the normal operation of the equipment and prevent leakage, and the shaft seal 29 can provide lubrication and reduce friction, thereby reducing the wear between the transmission shaft 28 and the sealing area, which helps to extend the service life of the equipment and reduce the frequency of maintenance and replacement of parts.

[0057] Secondly, after the food is completely minced and mixed, the heat pipe starts to heat up and work. The heat pipe is used to control the temperature in the furnace at 30-35°C for natural fermentation for 24-36 hours. During the fermentation, the servo cylinder 31 is controlled to drive the push rod 32 to move up and down. When the push rod 32 is driven to retract, the rotating plate 34 is pulled back. The fixed plate 36 is driven to rise through the movable installation of the rotating plate 34 and the buckle 35. Since the outer surface of the second connecting rod 37 fixedly installed on the inner surface of the fixed plate 36 is movably installed with a movable rod 38, the fixed plate 36 is moved upward. When the fermentation furnace 21 is ascending, the bottom of the fermentation furnace 21 is driven to rotate by the movable rod 38. When the fermentation furnace rotates, it rotates with the limit rod 39 as the center point. The fermentation furnace 21 is controlled to rotate by the continuous contraction of the top rod 32, so that the internal dishes are fully mixed during the fermentation process. While the fermentation furnace 21 rotates, the cam 311 is also driven to perform repeated lifting and lowering in the vertical Huacao. At this time, the driving rod 31 performs the lifting action with the incomplete gear 42. The incomplete gear 42 drives the driving gear 43 and the driving shaft 45 to rotate through the meshing gear teeth during the lifting process. The driving shaft 45 drives the linkage bevel gear 411 to rotate by driving the bevel gear 410 at the same time. The outer surfaces of the driving bevel gear 410 and the linkage bevel gear 411 are both provided with rotors 412, and a plurality of cutters 413 are cross-arranged on the outer walls of the two rotors, so that when the fermentation furnace 21 is driven to shake, the staff puts the dishes made with the fermentation liquid into the chassis through the feed inlet 47, and pre-cuts the dishes through the cross-arranged cutters 413. After cutting, the dishes fall from the discharge port into the vegetable basket prepared in advance and placed above the placement plate for standby use. After completion, the heat pipe rises to 120-130℃ for 30 minutes to sterilize the fermentation liquid in the furnace. After heat sterilization, the microorganisms in the fermentation liquid are completely killed, which can prevent the microorganisms from reproducing and fermenting. This can significantly extend the shelf life of the fermentation liquid and keep it stable during long-term storage and sales. In addition, the Aspergillus oryzae spore suspension will accumulate higher acidity and active substances such as ethanol during the fermentation process. Heat sterilization can stop the metabolic activity of the microorganisms and avoid further fermentation process to maintain the stability and quality of the fermentation liquid.

[0058] Finally, the liquid outlet flange 23 is connected to the liquid outlet pipe so that the fermented fermented liquid in the fermentation furnace 21 can be completely poured into the container, and the filter screen 24 is fixedly installed at the internal feed port of the fermentation furnace 21. It does not need secondary filtration and the design of the liquid outlet filter screen and can be used directly anywhere. After the fermented liquid is completely discharged, the servo cylinder 31 is controlled to drive the push rod 32 to be completely retracted. When the push rod 32 is fully retracted, the fixed plate 36 drives the fermentation furnace 21 to rotate 180° counterclockwise with the limit rod 39 as the center. After the fermentation furnace 21 rotates 180°, the feed cover 22 is directly below and facing the bottom plate 1. When the limit rod 39 rotates, the cam 311 on its outer surface will not rotate with it. Since the outer surface of the pad 312 is made of elastic rubber material, the pad 312 has good seismic resistance and can reduce the impact and vibration caused by earthquakes or mechanical vibrations. The cam 311 is subjected to the force to adhere to the pad 312, which effectively reduces the vibration and noise of the fermentation furnace 21 itself when the drive motor 27 is working, thereby ensuring the stability of the fermentation furnace 21 itself when the knife disc 212 cuts the food. After the fermentation furnace 21 rotates 180°, the pad 312 also effectively buffers the fermentation furnace to prevent the excessive gravity of the fermentation furnace from causing damage to the components. After the rotation of the fermentation furnace 21 is completed, a slag receiving bucket is placed above the bottom plate 1, and the feed cover 22 is opened to pour out the food residue in the filter screen 24. At the same time, the water pipe can be connected through the liquid outlet flange 23 to drain and clean the inside, thereby ensuring that the food residue in the filter screen 24 is completely poured out of the fermentation furnace and kept clean.

[0059] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present invention and fall within the protection scope of the present invention.
