Description

Technical Field

[0001] The invention belongs to the technical field of edible fungus strain cultivation, and in particular relates to a liquid strain cultivation device suitable for edible fungi. Background Art

[0002] Edible fungi strains are mycelium that are purely cultured using suitable culture media as carriers. They are the "seeds" in edible fungi production. Their quality directly affects the success or failure and efficiency of edible fungi production. Edible fungi strains are divided into solid strains and liquid strains based on their physical properties. Liquid strains have significant advantages over solid strains, such as short production cycle, convenient inoculation, fast fermentation, consistent fungus age, and easy mechanized operation. They are the future development trend of edible fungi strain cultivation.

[0003] In the prior art (the patent application with publication number CN208624261 U and patent name of edible fungus liquid strain culture device), the problems of incomplete sterilization and formation of dead corners were solved by improving the fermentation tank structure. In the process of implementing the technical solution, it was found that there were at least the following problems in the prior art.

[0004] At present, when culturing liquid strains of edible fungi, most of them adopt simple canning structures for packaging and culturing, which results in insufficient blending of the liquid strains of edible fungi and the added culture solution, causing insufficient nutrient supply to the liquid strains and a relatively dispersed distribution in the culture solution, which directly affects the ball formation effect of the liquid strains and reduces the culture rate of the liquid strains. In addition, when gas is injected into the liquid strains and the culture solution, the cultivation temperature requirements are not taken into account, and the temperature of the injected gas is not adaptively controlled, resulting in low precision in controlling the cultivation temperature of the liquid strains and reducing the success rate of the liquid strains.

[0038] The present invention is specifically described below in conjunction with the accompanying drawings and specific embodiments:

[0039] like Figure 1-Figure 13 As shown, a liquid strain culture device suitable for edible fungi of the present invention comprises a fixed box 1, both sides of the fixed box 1 are fixedly connected with cylinder barrels 2, and the other two sides of the fixed box 1 are fixedly connected with protective covers 3 through brackets, wherein the front of one set of protective covers 3 is fixedly connected with a PLC controller;

[0040] The fixed box 1 is provided with a shaking component 4 for blending the liquid strain and the culture solution, and the shaking component 4 includes a servo motor 41 fixed at the bottom center of the fixed box 1 and used as a unified driving source, and a support seat 46 is slidably connected to the fixed box 1, and the top of the support seat 46 is fixedly connected with a culture tank 47 for shaking and blending the liquid strain and the culture solution. The liquid strain and the culture solution filled in the four groups of culture tanks 47 are fully shaken and blended, so that the liquid strain can fully absorb nutrients, promote the formation of a large number of bacterial balls, and improve the culture rate of the liquid strain;

[0041] The cylinder barrel 2 is provided with a supply component 5 and a temperature control component 6 for regulating the temperature of the liquid bacteria and culture solution in the culture tank 47, and the supply component 5 includes a small integrated cold and hot machine 51 fixed at the top center of the support seat 46, and provides a cold and hot source supply to the liquid bacteria and culture solution in the culture tank 47, and conducts heating or cooling treatment on the liquid bacteria and culture solution in the four groups of culture tanks 47, so as to achieve precise temperature control effect and further improve the success rate of liquid bacteria culture.

[0042] like Figure 5-Figure 10As shown, the shaking component 4 also includes a swing arm 42 fixed on the output shaft of the servo motor 41. First, the servo motor 41 as a unified driving source drives the swing arm 42 to rotate, and one side of the swing arm 42 is slidably connected to a swing frame 43 through a convex head, and both sides of the swing frame 43 are fixedly connected to a limited slider 44, and a limited slide groove slidably matched with the limited slider 44 is opened on the side of the fixed box 1 close to the protective cover 3, and the outer side of the limited slider 44 is fixedly connected with a bent arm 45 fixedly matched with a supporting seat 46. The swing arm 42 drives the bent arms 45 on the two groups of limited sliders 44 through the swing frame 43 to achieve a horizontal back and forth displacement effect, and the two groups of bent arms 45 then drive the four groups of culture tanks 47 symmetrically distributed through the supporting seat 46 to shake synchronously horizontally, so that the liquid strains and culture fluid filled in the four groups of culture tanks 47 are fully shaken and blended, so that the liquid strains can fully absorb nutrients, promote the formation of a large number of bacterial balls, and improve the culture rate of the liquid strains;

[0043] Slide rail grooves 8 are provided on both sides of the top of the fixed box 1, and the inner cavity of the slide rail grooves 8 is slidably connected to a slide rail bar 9 fixedly matched with the support seat 46, which plays a role of sliding support for the support seat 46 that moves back and forth horizontally, thereby improving the stability and smoothness of the displacement of the support seat 46. The culture tanks 47 are distributed in an axially symmetrical and equidistant state along the central axis of the support seat 46, thereby improving the rationality of the distribution of the culture tanks 47 to prevent the support seat 46 from tilting and getting stuck due to the incorrect distribution position of the culture tanks 47. The bottom end of the outer side of the culture tank 47 is connected to a discharge pipe, and the top end of the outer side of the culture tank 47 is connected to a filling pipe, which is convenient for adding liquid bacteria and culture fluid into the culture tank 47, and can also discharge the liquid bacteria that have been cultured in the culture tank 47.

[0044] The supply assembly 5 also includes a three-way joint 52 connected to the top of the small integrated cold and hot machine 51, and both ends of the three-way joint 52 are connected to a delivery pipe 53, and the end of the delivery pipe 53 is connected to a four-way valve 54 connected and matched with the cylinder barrel 2. The small integrated cold and hot machine 51 provides a cold source or a hot source, and the three-way joint 52 and the delivery pipe 53 respectively supply the two cold sources or the hot sources to the two groups of four-way valves 54, and the centers of both sides of the swing frame 43 are fixedly connected with push rods 55, and the push rods 55 are connected to the cylinder barrel 2. The outer side is fixedly connected with a piston 56 that cooperates with the cylinder barrel 2 to do work. The swing frame 43 that moves back and forth horizontally drives the pistons 56 on the two push rods 55 to perform alternate reciprocating work in the two groups of cylinder barrels 2, generating a pressurized gas source in the two groups of cylinder barrels 2, and supplying it to the two groups of four-way valves 54 to form a pressurized cold source or a pressurized heat source. Both ends of the four-way valve 54 are connected with a pressurizing pipe 57, and then the four pressurizing pipes 57 are used to transport the pressurized cold source or the pressurized heat source formed in the four-way valve 54 in different areas.

[0045] A temperature sensor 10 is embedded in the bottom end of the four-way valve 54 to monitor the temperature of the pressurized cold source or pressurized heat source passing through the four-way valve 54 in real time to ensure that the temperature meets the cultivation requirement of the current liquid bacteria species, and the delivery pipe 53 and the boosting pipe 57 are both telescopic pipe styles that can be extended and retracted back and forth, which is convenient for the delivery pipe 53 and the boosting pipe 57 to follow the culture tank 47 in a horizontal back and forth displacement state to be extended and retracted without affecting its delivery work, and the delivery pipe 53, the boosting pipe 57, the discharge pipe and the filling pipe are all connected with a one-way valve, and the one-way valve is electrically controlled, which is convenient for automatic opening and closing control of the delivery pipe 53, the boosting pipe 57, the discharge pipe and the filling pipe.

[0046] The temperature control component 6 includes a three-way pipe 61 connected to the end of the boosting pipe 57, and the inner end of the three-way pipe 61 is connected to a delivery head 62 fixedly matched with the culture tank 47. The boosting cold source or the boosting heat source in the four boosting pipes 57 reaches the cavity 11 in the four groups of culture tanks 47 through the delivery heads 62 on the four three-way pipes 61, and the periphery of the liquid bacteria and culture solution in the four groups of culture tanks 47 is insulated to extend the heating and cooling time of the liquid bacteria and culture solution. The top of the three-way pipe 61 is connected to a bend pipe 63, and the end of the bend pipe 63 is connected to a rotating head 64, which rotates The inner cavity of the rotating head 64 is rotatably connected with a connecting head 65, and the bottom end of the connecting head 65 is connected with an air distribution rack 66 that rotates with the culture tank 47. The bottom end of the air distribution rack 66 is connected with a conduction pipe 67. The pressurized cold source or pressurization in the four three-way pipes 61 is also supplied to the conduction pipes 67 of the four groups of air distribution racks 66 by the rotating heads 64 and the connecting heads 65 on the four curved pipes 63. Then, the liquid strains and culture fluids in the four groups of culture tanks 47 are heated or cooled by conduction through the four groups of conduction pipes 67, so as to achieve a precise temperature control effect and further improve the success rate of liquid strain cultivation.

[0047] The inner cavity of the culture tank 47 is provided with a cavity 11 which is connected and cooperated with the delivery head 62, so as to facilitate the injection of a pressurized heat source or a pressurized cold source into the cavity 11, and to perform long-term temperature control on the liquid bacteria and culture solution in the culture tank 47 from the periphery, and the cavity 11 is not connected with the discharge pipe, the filling pipe and the air distribution rack 66, so as to prevent the pressurized heat source or the pressurized cold source in the cavity 11 from leaking into the discharge pipe, the filling pipe and the air distribution rack 66. The air distribution rack 66 and the conduction pipe 67 are distributed in a triangular equidistant state along the central axis of the connecting head 65, and the conduction pipe 67 adopts a thin-walled hollow design, which is conducive to the conduction of the pressurized heat source or the pressurized cold source through the conduction pipe 67 to the liquid bacteria and culture solution area in the culture tank 47, so as to perform sufficient and effective conduction heating or cooling treatment on them.

[0048] like Figure 10-12As shown, during the period of shaking and blending the liquid bacteria and the culture solution, a large number of bubbles will be generated, and the generation of dense bubbles not only occupies the blending space of the liquid bacteria and the culture solution, but also affects the nutrient uptake effect of the liquid bacteria, and does not have the function of stirring and defoaming. A defoaming component 7 is provided in the culture tank 47, and the defoaming component 7 includes an embedded cover 71 fixed to the bottom of the inner cavity of the culture tank 47, and a rack plate 72 is fixedly connected to the bottom of the inner side of the protective cover 3, and both sides of the rack plate 72 are meshed with a circular gear 73. When the circular gear 73 on the outer side of the culture tank 47 follows the horizontal displacement, since the rack plate 72 in the protective cover 3 is in a fixed state, the circular gear 73 in the water level displacement state rotates forward and reverse on the rack plate 72 at a frequency;

[0049] The inner cavity of the circular gear 73 is fixedly connected to a main bevel gear 74 that rotates with the culture tank 47 and the embedded cover 71 through a fixing rod, and the bottom of the main bevel gear 74 is meshed with a secondary bevel gear 75. The inner cavity of the secondary bevel gear 75 is fixedly connected to a stirring rack 76 that rotates with the embedded cover 71. The circular gear 73 drives the main bevel gear 74 to rotate in the forward and reverse directions with a frequency. The main bevel gear 74 drives the stirring rack 76 to rotate in the forward and reverse directions with the secondary bevel gear 75, so as to stir the liquid bacteria and culture solution in the culture tank 47 in the horizontal shaking state so that they are fully blended with each other. The stirring rack 76 is fixedly connected to the conduction tube 67 through a support rod. The stirring blades of the stirring rack 76 are arrayed with defoaming holes 77. At the same time, the rotating stirring rack 76 also uses the defoaming holes 77 to break and defoam the bubbles generated in the liquid bacteria and culture solution in the shaking and stirring states, which is beneficial to the full blending of the liquid bacteria and the culture solution, and also enhances the nutrient intake effect of the liquid bacteria.

[0050] The working principle of a liquid strain culture device suitable for edible fungi is as follows: first, the servo motor 41 is controlled to start and drive the swing arm 42 to rotate, the convex head on the swing arm 42 drives the swing frame 43 to adjust the horizontal back and forth displacement, and the swing frame 43 drives two groups of limit sliders 44 to slide horizontally back and forth in the limit slide groove, and the two groups of slide rail grooves 8 and the slide rail bars 9 cooperate with the support seat 46 to slide and support, and then the two groups of limit sliders 44 drive the four groups of culture tanks 47 axially symmetrically distributed on the support seat 46 through the two groups of bent arms 45 to perform synchronous horizontal shaking motion, so as to shake and blend the liquid strains and culture fluid filled in the four groups of culture tanks 47;

[0051] At the same time, according to the current cultivation temperature requirement of the liquid strain, the small integrated cold and hot machine 51 is controlled to start in advance and supply the generated cold source or heat source into the two groups of four-way valves 54 through the two delivery pipes 53 on the three-way joint 52, and the temperature sensor 10 monitors the temperature of the cold source or heat source supplied into the two groups of four-way valves 54, and while the swing frame 43 is adjusted to move back and forth horizontally, it also drives the pistons 56 on the two push rods 55 to work alternately in the two groups of cylinder barrels 2, and generates a pressurized gas source in the two groups of cylinder barrels 2 and supplies it into the two groups of four-way valves 54, and merges with the cold source or heat source supplied into the two groups of four-way valves 54 to form a pressurized cold source or a pressurized heat source, and then supplies the pressurized cold source or the pressurized heat source into the four pressurizing pipes 57 through the two groups of four-way valves 54;

[0052] At the same time, the pressurized cold source or pressurized heat source in the four pressurized pipes 57 reaches the cavity 11 in the four groups of culture tanks 47 through the four three-way pipes 61 and the four groups of conveying heads 62, and the liquid strains and culture fluids filled in the four groups of culture tanks 47 are heated or cooled for a long time from the periphery of the four groups of culture tanks 47, and the pressurized cold source or pressurized heat source in the four three-way pipes 61 also reaches the conduction pipe 67 at the bottom of the four groups of air distribution racks 66 through the four bent pipes 63 in turn through the four groups of rotating heads 64 and the connecting head 65. Since the conduction pipe 67 adopts a thin-walled hollow design, the four-way pressurized cold source or pressurized heat source supplied therein is also conducted to the liquid strains and culture fluids in the four groups of culture tanks 47 in a shaking state through the four groups of conduction pipes 67, and the liquid strains and culture fluids in the four groups of culture tanks 47 are heated or cooled to the predetermined requirements accordingly;

[0053] At the same time, the four groups of culture tanks 47 in horizontal shaking motion also drive the four groups of circular gears 73 to move horizontally. Since the rack plates 72 in the two groups of protective covers 3 are in a fixed state, the four groups of circular gears 73 in the horizontal displacement state rotate forward and reverse at a frequency on the two groups of rack plates 72. The four groups of circular gears 73 drive the four groups of main bevel gears 74 in the embedded covers 71 to rotate forward and reverse at a frequency. The four groups of main bevel gears 74 drive the stirring racks 76 on the four groups of secondary bevel gears 75 to rotate in the four groups of culture tanks 47, and stir the liquid bacteria and culture solution in the four groups of culture tanks 47 in the shaking state again. At the same time, the four groups of stirring racks 76 in the rotating state also break and defoam the dense bubbles generated in the liquid bacteria and the culture solution through the defoaming holes 77 until the liquid bacteria and the culture solution are fully blended. After standing and waiting for a certain period of time, the cultivation of the liquid bacteria in the four groups of culture tanks 47 is completed.

[0054] It should be noted that the specific model specifications of the servo motor 41 and the small integrated cold and hot machine 51 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be repeated in detail.

[0055] The power supply circuits of the servo motor 41 , the small integrated cooling and heating machine 51 , the temperature sensor 10 , and various valves are clear to those skilled in the art and will not be described in detail herein.

[0056] It is to be understood that the present invention is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention.
