Description

Technical Field

[0001] This invention relates to the field of food fermentation and storage technology, specifically to a packaging tank for fermenting food raw materials and its usage method. Background Technology

[0002] In the food processing industry, the fermentation of granular raw materials (such as soybeans, broad beans, chili peppers, and diced radishes) is a core process that determines the flavor and quality of many products, such as pickled products, fermented condiments, and fermented soy products. As a key piece of equipment suitable for small-batch, multi-category fermentation operations, the packaging tank is widely used in small and medium-sized food processing plants and laboratory research and development scenarios due to its advantages of independent temperature control and easy batch management. Its performance stability directly affects the controllability of the fermentation process and the qualification rate of the final product.

[0003] These types of dispensing tanks are mostly light-proof tanks. For the fermentation process of granular raw materials, monitoring the state of the material at the bottom of the tank is crucial. Since these dispensing tanks are mostly designed to be light-proof, to facilitate observation of the bottom material, existing dispensing tanks generally have a transparent observation window at the bottom of the tank. This allows operators to directly observe the state of the bottom material without opening the tank, thereby ensuring the continuity of the fermentation process and the stability of the anaerobic environment. However, the bottom material is prone to problems such as sedimentation and accumulation, local microbial imbalance, and enrichment and precipitation of fermentation products (such as organic acids, amino acids, etc.). If these conditions are not detected and adjusted in time, they can easily lead to the failure of fermentation of the entire batch of material.

[0004] In actual fermentation operations, the monitoring effect of transparent observation windows often fails to meet process requirements. Specifically, during the fermentation stage of granular raw materials, microbial metabolism continuously generates a large amount of water vapor. The fermentation environment inside the tank usually needs to be maintained within a specific temperature and humidity range. When this water vapor comes into contact with the relatively cool inner surface of the observation window, it will quickly condense into tiny water droplets and adhere to the surface. Subsequently, it will gradually gather into water mist or even a continuous water film. Such water mist or water film will severely obstruct the observation view, making it impossible for operators to clearly identify the morphology of the bacterial film of the granular raw materials at the bottom of the tank. Consequently, it is impossible to accurately judge the fermentation process and adjust the process parameters in a timely manner. If the tank lid is opened to obtain a clear view, it will disrupt the anaerobic fermentation environment inside the tank, which will not only introduce the risk of contamination by miscellaneous bacteria but also cause sudden changes in temperature and humidity inside the tank. This will seriously affect fermentation efficiency and process stability, ultimately reducing the uniformity of product quality.

[0005] Therefore, in response to the above problems, a packaging tank for fermenting food raw materials and its usage method are proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a packaging container for fermenting food raw materials and a method for using it, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A dispensing tank for fermenting food raw materials and its method of use are disclosed. The tank includes a tank body with operating extension mechanisms installed on both sides of the bottom front face of the tank body. An observation component is installed at the center of the bottom front face of the tank body, and the observation component is connected to the operating extension mechanisms. The operating extension mechanism includes a protective tube, with a sealing glove glued to one end of the inner side of the protective tube. A finger sleeve assembly is integrally formed on the outer side of the sealing glove. The observation component includes an observation cover, with a vent pipe fixed through the top of the observation cover. An observation cap assembly is fixed to the front of the observation cover. A protruding boss is fixed at the center of the bottom inner side of the observation cover, and a material observation element is secured inside the boss, extending to the bottom of the observation cover. A folded tube is fixed through the top of the vent pipe, with a water collection cylinder fixed through the top of the folded tube, and a buffer airbag is fixedly connected to the top of the folded tube.

[0009] As a further optimization of the present invention, the back of the observation cover includes a first arc-shaped inclined region and a second arc-shaped inclined region. The first arc-shaped inclined region is located at the top of the back of the observation cover, and its inclination angle relative to the horizontal plane is 60°-65°. The second arc-shaped inclined region is located at the bottom of the back of the observation cover, and its inclination angle relative to the horizontal plane is 10°-15°, and it is smoothly connected to the first arc-shaped inclined region. A water guide groove is provided at the front of the inner side of the observation cover.

[0010] As a further optimization of the present invention, the finger sleeve assembly includes a finger sleeve body, the inner side of the finger sleeve body has a cavity structure, a contact ring is installed at the front end of the finger sleeve body, and a plurality of wiper blades arranged in a circular array are integrally formed on the inner side of the finger sleeve body.

[0011] As a further optimization of the present invention, the wiper blade is parallel to the finger sleeve body, and an arc-shaped groove is formed at the center of the wiper blade.

[0012] As a further optimization of the present invention, the observation cover assembly includes a cover body, an observation glass is embedded in the front of the inner side of the cover body, a magnifying lens is integrally formed at the bottom of the observation glass, a fixing seat is fixed at the top of the rear side of the inner side of the cover body, two supporting inclined plates are installed below the fixing seat, and multiple finger sleeve grooves for cooperating with the finger sleeve assembly are opened at the rear of the supporting inclined plates.

[0013] As a further optimization of the present invention, a water storage cylinder is threadedly connected to the center of the bottom end of the cover, and the inner side of the water storage cylinder is connected to the water receiving groove inside the cover.

[0014] As a further optimization of the present invention, the front of the supporting inclined plate is in contact with the back of the observation glass, the two supporting inclined plates are symmetrically distributed from left to right, the supporting inclined plate has an inclined structure, its cross-section is an isosceles trapezoidal structure, and its bottom end is fixedly connected to the cover.

[0015] As a further optimization of the present invention, the position of the water guiding channel corresponds to the position of the water receiving channel, and the bottom end of the inner side of the water guiding channel and the bottom end of the inner side of the water receiving channel are connected by an inclined structure.

[0016] As a further optimization of the present invention, the material observation device includes a chuck, observation slots are provided on both sides of the chuck, an air nozzle is integrally formed at the center of the top of the chuck, a material passage pipe is fixed at the center of the bottom of the chuck, and a material collection bowl is fixed at the bottom of the material passage pipe, the lower surface of the material collection bowl is hemispherical.

[0017] A method for using a dispensing container for fermenting food ingredients:

[0018] Step 1: Raw material filling operation. Open the tank inlet and fill the tank with granular fermentation raw materials. After the raw materials come into contact with the back of the observation cover, they will slide naturally along the first arc-shaped inclined area at 60°-65° and the second arc-shaped inclined area at 10°-15°, gradually covering the back of the observation cover. After filling is completed, seal the inlet.

[0019] Step 2: During fermentation, the operator observes the state of the material at the bottom of the tank through the observation glass of the observation cover assembly. With the help of the integrated magnifying lens, the morphology of the granular material and the growth of the bacterial film can be clearly observed. The tank can be opened directly to achieve intuitive monitoring, avoiding damage to the fermentation environment. The operator can check whether there are problems such as sedimentation and accumulation or local color abnormalities in the material. If the field of vision is clear, the status can be recorded directly. If water vapor is found to be obstructing the surface of the observation glass or observation cover, the operator will proceed to the water vapor cleaning stage.

[0020] Step 3: Moisture Removal Operation Stage. Pass your palm through the protective tube of the operating insertion mechanism and into the sealed glove. Fit your fingers into the finger sleeve body of the finger sleeve assembly. The contact ring fits against the tip of your finger to provide support. The gas pressure generated by fermentation inside the tank acts on the buffer airbag through the vent tube, causing the airbag to expand and balance the internal and external pressures. This prevents the hand from being unable to fit smoothly due to pressure differences. Slowly push your hand to insert the finger sleeve assembly into the space between the observation hood and the observation cover assembly. Use the squeegee blades in the circular array on the inner side of the finger sleeve body to scrape away moisture by moving them against the inner side of the observation hood and the back of the observation glass. The arc groove in the center of the squeegee blades adapts to the curved surface of the observation hood to ensure thorough cleaning. At the same time, the finger sleeve groove provides guidance for the movement of the finger sleeve assembly and avoids interference with the support plate.

[0021] Step 4: Liquid collection and treatment stage. After the scraped water vapor condenses into droplets, it slides down the water guide groove inside the observation cover. Because the bottom of the water guide groove and the water receiving groove are connected by an inclined structure, the liquid flows smoothly into the water receiving groove. The liquid in the water receiving groove eventually flows into the threaded water storage cylinder. At the same time, the water vapor condensed on the wall of the bend tube slides down along the bend structure and flows into the water collection cylinder at the top. Periodically unscrew the water storage cylinder and the water collection cylinder, pour out the liquid, and then reset them.

[0022] Step 5: Carefully examine the details of the bacterial film growth at the protrusion through the observation slots on both sides of the chuck of the material observation piece. If further confirmation is needed, gently pull the chuck to move the chuck and the feed tube slightly up and down. With the support of the hemispherical collection bowl at the bottom, observe the state of the material. Move the finger sleeve assembly to the finger sleeve groove and use the groove wall to scrape off the residual liquid attached to the scraper blade of the finger sleeve assembly. Then slowly withdraw your hand, and the sealing glove will automatically reset.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. This invention addresses the core problem of existing fermentation dispensing tanks' observation windows being easily blocked by moisture by the combination of the operating insertion mechanism and the observation components. Through the cooperation of the sealed gloves and finger sleeve components of the operating insertion mechanism, condensed moisture on the observation cover and observation glass surface can be precisely scraped off with the help of a scraper without opening the tank. At the same time, the water guide trough, water receiving trough, and water storage cylinder form a complete liquid collection system, preventing liquid backflow and contaminating the material, ensuring a continuously clear observation field, and effectively avoiding the problem of traditional open-lid observation disrupting the anaerobic fermentation environment.

[0025] 2. Improved accuracy and ease of operation in monitoring the fermentation process. The magnifying lens of the observation cap assembly can clearly capture the fine details such as the bacterial film of the material. The material observation piece, through the observation groove and the controllable flipping structure, enables a comprehensive exploration of the local details and internal state of the material at the protrusion. During the adjustment process, the finger sleeve groove provides guidance for operation, and the air nozzle can easily control the flipping of the material. The overall structure is adapted to the needs of lightweight operation and reduces the monitoring difficulty for operators.

[0026] 3. This solution ensures a stable fermentation environment and product quality through multi-structure collaborative design. The double-arc inclined area of ​​the observation hood guides the raw materials to be evenly covered, avoiding accumulation and obstruction. The supporting inclined plate forms a stable support structure to resist the influence of changes in gas pressure inside the tank on the observation components, providing reliable data support for precise process control and effectively improving the quality uniformity and pass rate of small-batch, multi-category fermented products.

[0044] Please see Figures 1-11 The present invention provides a technical solution:

[0045] A dispensing tank for fermenting food raw materials and its usage method include a tank body 1. Operating extension mechanisms 2 are installed on both sides of the bottom front face of the tank body 1. An observation component 3 is installed at the center of the bottom front face of the tank body 1, and the observation component 3 is connected to the operating extension mechanisms 2. The operating extension mechanism 2 includes a protective tube 21. A sealing glove 22 made of rubber material is glued and fixed to one end of the inner side of the protective tube 21. A finger sleeve assembly 23 is integrally formed on the outer side of the sealing glove 22. The observation component 3 includes an observation cover 30. A vent pipe 32 is fixed through the top of the observation cover 30. An observation cover assembly 34 is fixed to the front of the observation cover 30. A protruding boss 35 is fixed at the center of the bottom inner side of the observation cover 30. A material observation element 36 is clamped inside the boss 35 and extends to the bottom of the observation cover 30. A folded tube 37 is fixed through the top of the vent pipe 32. A water collection cylinder 38 is fixed through the top of the folded tube 37, and a buffer airbag 39 is fixedly connected to the top of the folded tube 37.

[0046] As a further implementation of this solution, the back of the observation cover 30 includes a first arc-shaped inclined area and a second arc-shaped inclined area. The first arc-shaped inclined area is located at the top of the back of the observation cover 30, with an inclination angle of 60°-65° relative to the horizontal plane. The second arc-shaped inclined area is located at the bottom of the back of the observation cover 30, with an inclination angle of 10°-15° relative to the horizontal plane, and is smoothly connected to the first arc-shaped inclined area. A water guide groove 31 is provided at the front of the inner side of the observation cover 30. The raw materials are guided to slide down naturally and completely cover the back of the observation cover 30 through the first arc-shaped inclined area and the second arc-shaped inclined area. At the same time, the water guide groove 31 provides a channel for water vapor accumulation, solving the problem that fermentation water vapor cannot be discharged after condensation.

[0047] As a further implementation of this solution, the finger sleeve assembly 23 includes a finger sleeve body 231. The inner side of the finger sleeve body 231 has a hollow structure. A contact ring 232 is installed at the front end of the finger sleeve body 231. Multiple wiper blades 233 arranged in a circular array are integrally formed on the inner side of the finger sleeve body 231. The hollow structure of the finger sleeve body 231 is adapted to finger operation. The contact ring 232 improves the stability of operation. The circular array of wiper blades 233 can cover the surface of the observation cover 30 and the observation glass 342 in all directions.

[0048] As a further implementation of this solution, the wiper blade 233 and the finger sleeve body 231 are parallel to each other. An arc-shaped groove is provided at the center of the wiper blade 233. The arc-shaped groove facilitates the bending of the wiper blade 233 during wear and makes it easy for the finger sleeve body 231 to flip.

[0049] As a further implementation of this solution, the observation cover assembly 34 includes a cover body 341, an observation glass 342 is embedded in the front of the inner side of the cover body 341, a magnifying lens 343 is integrally formed at the bottom of the observation glass 342, a fixing seat 344 is fixed at the top of the rear of the inner side of the cover body 341, two supporting inclined plates 345 are installed below the fixing seat 344, and multiple finger sleeve grooves 346 are opened at the rear of the supporting inclined plates 345 for cooperating with the finger sleeve assembly 23. The magnifying lens 343 can clearly observe the fine state of the material and bacterial film, and the groove wall of the finger sleeve groove 346 is used to scrape off the residual liquid attached to the scraper blade 233 of the finger sleeve assembly 23 to ensure the subsequent use effect of the scraper blade 233.

[0050] As a further implementation of this scheme, a water storage cylinder 348 is threadedly connected to the center of the bottom end of the cover 341. The inner side of the water storage cylinder 348 is connected to the water receiving trough 347 inside the cover 341. The water receiving trough 347 collects the water vapor and liquid that is scraped off. The water storage cylinder 348 is detachably collected through the threaded connection, which is convenient for regular cleaning of the liquid and avoids the liquid flowing back and contaminating the fermentation material.

[0051] As a further implementation of this solution, the front of the support inclined plate 345 is attached to the back of the observation glass 342. The two support inclined plates 345 are symmetrically distributed from left to right. The support inclined plate 345 has an inclined structure and its cross-section is an isosceles trapezoidal structure. The bottom end is fixedly connected to the cover 341. The symmetrically distributed support inclined plates 345 form a stable triangular support structure, which enhances the overall structural strength of the observation cover assembly 34 and prevents the cover 341 from deforming due to changes in gas pressure inside the tank 1 during fermentation. At the same time, attaching to the back of the observation glass 342 can help disperse pressure, protect the observation glass 342 from cracking, and ensure the continuous and stable observation function.

[0052] As a further implementation of this solution, the position of the water guide trough 31 corresponds to the position of the water receiving trough 347. The bottom of the inner side of the water guide trough 31 and the bottom of the inner side of the water receiving trough 347 are connected by an inclined structure. The corresponding connection design of the water guide trough 31 and the water receiving trough 347, together with the inclined structure, realizes the smooth flow of the accumulated liquid and avoids the accumulation of liquid at the connection point.

[0053] As a further implementation of this solution, the material observation component 36 includes a chuck 361, with observation slots on both sides of the chuck 361. An air nozzle 362 is integrally formed at the center of the top of the chuck 361, and a feed pipe 363 is fixed at the center of the bottom of the chuck 361. A collection bowl 364 is fixed at the bottom of the feed pipe 363, and the lower surface of the collection bowl 364 has a hemispherical structure. With the help of the observation slots on both sides of the chuck 361 in the material observation component 36, the local details of the material at the protrusion 35 can be accurately observed. The air nozzle 362 can be used to easily control the chuck 361 to drive the feed pipe 363 and the collection bowl 364 to move slightly up and down, so as to achieve non-destructive turning of the material and solve the problem that the existing observation method cannot fully explore the growth status of the bacterial film inside the material.

[0054] Work process: Raw material filling operation: Open the feed port of tank 1 and fill the tank with granular fermentation raw materials such as soybeans and peppers. After the raw materials come into contact with the back of the observation cover 30, they will slide naturally along the first arc-shaped inclined area of ​​60°-65° and the second arc-shaped inclined area of ​​10°-15°, gradually covering the back of the observation cover 30. After filling is completed, seal the feed port to ensure an anaerobic fermentation environment inside the tank.

[0055] During fermentation, the operator can check the status of the material at the bottom of the tank through the observation glass 342 of the observation cover assembly 34. With the help of the integrated magnifying lens 343, the morphology of the granular material and the growth of the bacterial film can be clearly observed. The tank body 1 can be opened directly to achieve intuitive monitoring, avoiding damage to the fermentation environment. The operator can check whether there are problems such as sedimentation and accumulation or local color abnormalities in the material. If the field of vision is clear, the status can be recorded directly. If water vapor is found to be obstructing the surface of the observation glass 342 or the observation cover 30, the operator will proceed to the water vapor cleaning stage.

[0056] During the water vapor cleaning operation, the palm is passed through the protective tube 21 of the operating insertion mechanism 2 and inserted into the sealed glove 22, so that the fingers are fitted into the finger sleeve body 231 of the finger sleeve assembly 23. The contact ring 232 fits against the front end of the finger to provide support. The gas pressure generated by fermentation in the tank acts on the buffer air bag 39 through the vent pipe 32, causing the air bag to expand and balance the internal and external pressure, avoiding the inability of the hand to be inserted smoothly due to pressure difference. The hand is slowly pushed so that the finger sleeve assembly 23 is inserted into the space between the observation cover 30 and the observation cap assembly 34. The water scraper 233 with the circular array on the inner side of the finger sleeve body 231 is used to scrape away water vapor by moving against the inner side of the observation cover 30 and the back of the observation glass 342. The arc groove in the center of the water scraper 233 is adapted to the curved surface of the observation cover 30 to ensure cleaning without dead corners. At the same time, the finger sleeve groove 346 provides guidance for the movement of the finger sleeve assembly 23 to avoid interference with the support inclined plate 345.

[0057] During the liquid collection and treatment stage, the scraped water vapor condenses into droplets and slides down the water guide groove 31 inside the observation cover 30. Because the bottom of the water guide groove 31 and the water receiving groove 347 are connected by an inclined structure, the liquid flows smoothly into the water receiving groove 347. The liquid in the water receiving groove 347 eventually flows into the threaded water storage cylinder 348. At the same time, the water vapor condensed on the wall of the folded tube 37 slides down along the bent structure and flows into the water collection cylinder 38 at the top. The water storage cylinder 348 and the water collection cylinder 38 are unscrewed periodically, the liquid is poured out and then reset to prevent the liquid from flowing back and contaminating the materials.

[0058] By carefully examining the microbial film growth details of the material at the protrusion 35 through the observation slots on both sides of the chuck 361 of the material observation piece 36, if further confirmation is needed, gently pull the air nozzle 362 at the top of the chuck 361 to move the chuck 361 and the feed tube 363 slightly up and down. With the support of the hemispherical collection bowl 364 at the bottom, the material is slightly turned over to observe the material state more closely. Move the finger sleeve assembly 23 to the finger sleeve groove 346 and use the groove wall to scrape off the residual liquid attached to the scraper blade 233 of the finger sleeve assembly 23 to ensure the subsequent use effect of the scraper blade 233. Then slowly withdraw your hand, and the sealing glove 22 will automatically reset.

After the raw materials come into contact with the back of the observation cover (30), they will slide down naturally along the first arc-shaped inclined area and the second arc-shaped inclined area, gradually covering the back of the observation cover (30). After filling is completed, seal the feed port. Step 2: During fermentation, the operator observes the state of the material at the bottom of the tank through the observation glass (342) of the observation cover assembly (34). With the help of the integrated magnifying lens (343), the operator can clearly observe the morphology of the granular material and the growth of the bacterial film. The tank (1) can be opened without opening it, thus achieving intuitive monitoring and avoiding damage to the fermentation environment. The operator can confirm whether there are problems such as sedimentation and accumulation or local color abnormalities in the material through observation. If the field of vision is clear, the status can be recorded directly. If water vapor is found to be obstructed on the surface of the observation glass (342) or the observation cover (30), the operator will proceed to the water vapor cleaning stage. Step 3: During the water vapor removal operation, pass your palm through the protective tube (21) of the operating insertion mechanism (2) and into the sealed glove (22). Place your fingers into the finger sleeve body (231) of the finger sleeve assembly (23). The contact ring (232) provides support to the fingertips. The gas pressure generated during fermentation inside the tank acts on the buffer airbag (39) through the vent pipe (32), causing the airbag to expand and balance the internal and external pressures. This prevents the hand from being unable to smoothly insert due to pressure differences. Slowly push your hand to allow the finger sleeve assembly to... The component (23) extends into the space between the observation cover (30) and the observation cover assembly (34). Using the circular array of wiper blades (233) on the inner side of the finger sleeve body (231), it moves to wipe away water vapor against the inner side of the observation cover (30) and the back of the observation glass (342). The arc groove in the center of the wiper blade (233) is adapted to the curved surface of the observation cover (30) to ensure cleaning without dead corners. At the same time, the finger sleeve groove (346) provides guidance for the movement of the finger sleeve assembly (23) to avoid interference with the support inclined plate (345). Step 4: Liquid collection and treatment stage. After the scraped water vapor condenses into droplets, it slides down the water guide groove (31) on the inner side of the observation cover (30). Since the bottom of the water guide groove (31) and the water receiving groove (347) are connected by an inclined structure, the liquid flows smoothly into the water receiving groove (347). The liquid in the water receiving groove (347) eventually flows into the threaded water storage cylinder (348). At the same time, the water vapor condensed on the wall of the folded tube (37) slides down along the bent structure and flows into the water collection cylinder (38) at the top. Periodically unscrew the water storage cylinder (348) and the water collection cylinder (38), pour out the liquid and reset them. Step 5: Carefully examine the details of the bacterial film growth at the protrusion (35) through the observation slots on both sides of the chuck (361) of the material observation piece (36). If further confirmation is needed, gently pull the air nozzle (362) at the top of the chuck (361) to move the chuck (361) and the feed tube (363) slightly up and down. With the support of the hemispherical collection bowl (364) at the bottom, observe the state of the material. Move the finger sleeve assembly (23) to the finger sleeve groove (346) and use the groove wall to scrape off the residual liquid attached to the scraper (233) of the finger sleeve assembly (23). Then slowly withdraw your hand, and the sealing glove (22) will automatically reset.
