Description

Technical Field

[0001] This invention relates to the field of fermentation equipment technology, and in particular to a fermentation equipment specifically for animal feed. Background Technology

[0002] In existing technologies, when conducting small-scale mixed fermentation, it is necessary to manually put the raw materials and inoculum into a small fermentation tank and stir them manually to achieve mixing. This method has poor sealing performance, is time-consuming and labor-intensive, and has poor mixing effect. After sealing, it relies solely on the natural reaction of the raw materials and inoculum for fermentation, resulting in a long fermentation cycle and low production efficiency. After fermentation, it is also necessary to disassemble the relevant parts for manual cleaning, which is not only cumbersome and incomplete, but also easily leaves fermentation material that affects the purity of subsequent fermentation and increases maintenance costs.

[0003] Existing technologies for fermentation production lack targeted gas production control mechanisms, resulting in the inability to timely release carbon dioxide produced during fermentation. This can easily damage the fermentation tank due to excessive internal pressure and lead to waste due to direct gas loss. When partially removing material, opening the discharge valve at the bottom of the fermentation tank and then sealing it allows external gases to seep in, which can cause the growth of unwanted microorganisms and shorten the shelf life of the remaining fermented material. Relying solely on the weight of the material for complete removal results in low discharge efficiency. Furthermore, the fermented material adhering to the circular cap after removal requires manual removal and cleaning, making the process cumbersome, time-consuming, and labor-intensive.

[0004] To address the above problems, a special fermentation equipment for animal feed is proposed. Summary of the Invention

[0007] More preferably, it also includes a water delivery trough, a water delivery valve, a first water delivery pipe, elastic elements, a plug, and a plug plate; a water delivery trough is provided inside the mixing cylinder; a water delivery valve is fixedly connected to the upper part of the mixing cylinder; a first water delivery pipe is fixedly connected to each mixing blade; several elastic elements are fixedly connected to each mixing blade; a plug is fixedly connected to each elastic element; a plug plate is fixedly connected to each plug, and the plug plate is connected to the mixing blade.

[0008] More preferably, it also includes a square through groove, a diversion groove, a second water supply pipe, a water outlet, and a permeable membrane; each stirring blade has several square through grooves; each stirring blade has a diversion groove for diverting water from the first water supply pipe; a second water supply pipe is fixedly connected to the upper and lower sides of each stirring blade; each stirring blade has several water outlets, and each water outlet is located on the upper side of the square through groove and connected to the second water supply pipe; a permeable membrane is fixedly connected to the bottom of each water outlet.

[0009] More preferably, the bottom of the fermentation tank is designed to be an inverted cone shape.

[0010] More preferably, a groove is provided on the rotating shaft.

[0011] A more preferable option is to flare the outlet.

[0012] More preferably, the stirring blades are angled.

[0013] More preferably, the device includes a third driving component, a circular pressure cap, a vent, a breathable membrane, a limit detection frame, a gas tank, a suction pipe, and an electrically controlled valve; two third driving components are symmetrically fixed to the upper side of the circular pressure cap; a circular pressure cap is slidably connected inside the fermenter and connected to the output end of the third driving component; three vents are opened circumferentially inside the circular pressure cap; a breathable membrane is fixed to the bottom of each vent; a limit detection frame for limiting the circular pressure cap and detecting the gas inside the fermenter is fixed to the bottom of the circular pressure cap; a gas tank is fixed to the upper side of the circular pressure cap; a suction pipe is fixed to the bottom of the gas tank; and an electrically controlled valve for controlling the opening and closing of the suction pipe is fixed to the suction pipe.

[0014] More preferably, a first scraper is fixedly attached to the upper side of each stirring blade; and a second scraper is fixedly attached to the side of each stirring blade away from the rotating shaft.

[0015] More preferably, the circular cap fits tightly against the inner wall of the fermenter.

[0016] Compared with the prior art, the present invention has the following advantages: The present invention realizes the replacement of manual stirring by the rotation and reciprocating motion of the stirring blades, so as to achieve uniform mixing of raw materials and inoculum, shorten the fermentation cycle and improve production efficiency; during cleaning, there is no need to disassemble the fermentation tank. The stirring blades and the inner wall of the fermentation tank are quickly cleaned by water flushing and the cooperation of the first scraper and the second scraper, avoiding residue and reducing maintenance costs. Moreover, the mixing and cleaning are automated, reducing manual intervention and adapting to large-scale production.

[0017] By using a third driving component to push the circular pressure cap downwards in conjunction with the limit detection frame, electrically controlled valve, and gas tank, carbon dioxide produced during fermentation can be discharged and stored in a timely manner, preventing damage to the equipment due to excessive gas pressure inside the tank and enabling secondary utilization of gas. After partial material removal, the circular pressure cap squeezes out the infiltrated external gas, preventing the growth of contaminating bacteria and extending the storage period of the remaining fermentation material. When removing all material, the circular pressure cap moves downwards to press the material, improving discharge efficiency. The first scraper of the stirring blade rotates and scrapes off the fermentation material adhering to the circular pressure cap, allowing for cleaning without disassembly, simplifying the process, improving cleaning efficiency, and reducing overall labor costs and operational complexity.

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0021] Example 1: A special fermentation device for animal feed, such as Figures 1-5 As shown, it includes a fixed frame 1, a fermentation tank 2, and a round cover 3; the fermentation tank 2 is fixedly connected to the fixed frame 1; the round cover 3 is installed on the fermentation tank 2; a discharge valve 4 is fixedly connected to the bottom of the fermentation tank 2; several bolts 2001 are arranged circumferentially on the upper side of the fermentation tank 2, and each bolt 2001 is connected to the round cover 3, which can fix the round cover 3 on the fermentation tank 2 to prevent external gas from entering the tank and causing the fermentation process to be disrupted; It also includes a first drive component 101, a rotating shaft 102, a stirring cylinder 103, stirring blades 105, and a second drive component 109; the first drive component 101 is installed on the round cover 3; the first drive component 101 is a motor; the output end of the first drive component 101 is fixedly connected to the rotating shaft 102, and the bottom of the rotating shaft 102 is screwed to the inner wall of the fermentation tank 2; the stirring cylinder 103 is slidably connected to the rotating shaft 102; four stirring blades 105 are fixedly connected to the stirring cylinder 103 circumferentially, which can be used to stir the fermentation material, so that the inoculum and raw materials can be further mixed; the second drive component 109 is fixedly connected inside the round cover 3, the second drive component 109 is an electric push rod, and the second drive component 109 is connected to the stirring cylinder 103, which can be used to push the stirring cylinder 103 to move up and down.

[0022] It also includes a water delivery trough 10301, a water delivery valve 104, a first water delivery pipe 10503, elastic elements 106, plugs 107, and blocking plates 108; the water delivery trough 10301 is opened inside the stirring cylinder 103; the water delivery valve 104 is fixedly connected to the upper part of the stirring cylinder 103; the first water delivery pipe 10503 is fixedly connected to each stirring blade 105; several elastic elements 106 are fixedly connected to each stirring blade 105; the elastic elements 106 are springs; a plug 107 is fixedly connected to each elastic element 106; a blocking plate 108 is fixedly connected to each plug 107, and the blocking plate 108 is connected to the stirring blade 105, and the blocking plate 108 can block the first water delivery pipe 10503.

[0023] It also includes a square through-channel 10504, a diversion channel 10505, a second water supply pipe 10506, a water outlet 10507, and a permeable membrane 10508; each stirring blade 105 has several square through-channels 10504, which can reduce stirring resistance, thereby allowing the raw materials and inoculum to be further mixed; each stirring blade 105 has a diversion channel 10505; the upper and lower sides of each stirring blade 105 are fixedly connected to the second water supply pipe 10506; each stirring blade 105 has several water outlets 10507, and each water outlet 10507 is located on the upper side of the square through-channel 10504 and connected to the second water supply pipe 10506; the bottom of each water outlet 10507 is fixedly connected to a permeable membrane 10508, which allows the water in the water outlet 10507 to flow out without allowing external mixing materials to enter the water outlet 10507.

[0024] The bottom of fermentation tank 2 is designed in an inverted cone shape, which makes it easier to remove the material after fermentation and improves work efficiency.

[0025] The rotating shaft 102 is provided with a sliding groove, which can be matched with the stirring cylinder 103, so that the stirring cylinder 103 can move up and down along the rotating shaft 102.

[0026] The outlet 10507 is flared to allow water in the second water pipe 10506 to be further diffused onto the square channel 10504, thereby cleaning the square channel 10504.

[0027] The stirring blades 105 are angled, which reduces resistance during stirring and facilitates the mixing of raw materials and microorganisms.

[0028] In existing mixed fermentation technology, raw materials and inoculum need to be manually placed into a small fermentation tank and stirred to achieve mixing. This method of stirring by workers is time-consuming and labor-intensive, and the mixing effect is poor. Using plastic film or other equipment to seal the small fermentation tank results in poor sealing. After sealing, relying solely on natural reaction for fermentation leads to a long cycle and low efficiency. After fermentation, the parts need to be disassembled and cleaned manually, which is cumbersome and the cleaning is not thorough. Fermentation residue can easily remain, affecting the purity of subsequent processes and increasing equipment maintenance costs.

[0029] To address the aforementioned issues, existing technologies typically employ manual mixing when mixing raw materials and inoculum. This method is time-consuming, labor-intensive, and fails to ensure effective mixing of the raw materials and inoculum. After placing the raw materials and inoculum into the fermentation tank 2 and installing the relevant components, the round cover 3 is placed on top and secured to the upper part of the fermentation tank 2 with bolts 2001. Then, the first drive unit 101 is activated to control the rotation speed of the rotating shaft 102, while the second drive unit 109 is activated to push the stirring cylinder 103 downwards. When the stirring cylinder 103 moves downwards and contacts the stirring blades 105, the stirring blades 105 mix the inoculum and raw materials. As the stirring blades 105 reciprocate up and down at the bottom, the inoculum and raw materials in the upper and lower parts are further mixed, thereby shortening the fermentation cycle and improving production efficiency.

[0030] When fermentation is complete and the fermentation tank 2 needs to be cleaned with water, the existing technology requires disassembling the entire tank and then cleaning the interior, which is a cumbersome process. After connecting the water inlet pipe to the water supply valve 104, the water supply valve 104 is opened, and water enters the water supply trough 10301, then disperses into the surrounding stirring blades 105. The water is then transported to the other side of the stirring blades 105 through the first water supply pipe 10503. The water then impacts the plug 107, compressing the elastic element 106, and the water enters the diversion trough 10505, and then enters the second diversion trough located on the upper and lower sides of the stirring blades 105. The second water supply pipe 10506 then sprays water from the outlet 10507 to clean the square channel 10504, thereby improving cleaning efficiency. When the plug 107 moves, since the plug plate 108 is connected to the plug 107, the plug plate 108 will also move away from the rotating shaft 102 along with the plug 107, so that water can flow to the inner wall of the fermentation tank 2. At the same time as water is supplied, the stirring blade 105 will also rotate, so that the second scraper 10502 can scrape off the fermentation material adhering to the inner wall of the fermentation tank 2, thereby cleaning the inner wall of the fermentation tank 2 and improving cleaning efficiency.

[0031] Example 2: Based on Example 1, such as Figure 6 As shown, it includes a third driving component 201, a circular pressure cap 202, a vent 20201, a breathable membrane 20202, a limit detection frame 203, a gas tank 204, a suction pipe 205, and an electrically controlled valve 206; two third driving components 201 are symmetrically fixed to the upper side of the circular cap 3; the third driving component 201 is an electric push rod; the circular pressure cap 202 is slidably connected inside the fermenter 2 and is connected to the output end of the third driving component 201; the circular pressure cap 202 has an inner circumferential opening. There are three vents 20201; each vent 20201 has a breathable membrane 20202 fixed to its bottom, which allows gas from the bottom of the circular cap 202 to enter the top, while preventing fermentation material from the bottom from entering the top; a limit detection frame 203 is fixed to the bottom of the circular cap 3; a gas tank 204 is fixed to the upper side of the circular cap 3; a suction pipe 205 is fixed to the bottom of the gas tank 204, which can extract gas from the fermentation tank 2; an electric control valve 206 is fixed to the suction pipe 205.

[0032] Each stirring blade 105 is fixedly connected to the upper side of a first scraper 10501; each stirring blade 105 is fixedly connected to the side away from the rotating shaft 102 by a second scraper 10502; the first scraper 10501 and the second scraper 10502 can scrape off the fermentation material adhering to the circular pressure cap 202 and the inner wall of the fermentation tank 2.

[0033] The circular cap 202 fits tightly against the inner wall of the fermentation tank 2, preventing the fermentation material at the bottom from entering the upper part of the circular cap 202 from the contact area between the circular cap 202 and the inner wall of the fermentation tank 2.

[0034] Furthermore, during fermentation production, there is no specific gas production control mechanism. The carbon dioxide gas produced during fermentation cannot be discharged in time, which can easily damage the fermentation tank 2 due to excessive gas pressure inside the tank, and the gas is directly lost, resulting in waste. When partially removing material, the discharge valve 4 at the bottom of the fermentation tank 2 is opened to remove the material and then closed. The seeping external gas will cause the growth of miscellaneous bacteria and shorten the storage period of the remaining fermented material. When removing all the material, the material is discharged by its own weight, which is inefficient. After removing the material, the fermented material adhering to the circular cap 202 needs to be manually removed and cleaned, which is a cumbersome, time-consuming and labor-intensive process.

[0035] To address the aforementioned issues, after a period of fermentation, the internal microbial fermentation will produce a significant amount of carbon dioxide gas, leading to increased internal pressure. If left uncontrolled, this could damage fermenter 2. In this case, the third drive unit 201 can be activated, pushing the circular pressure cap 202 downwards. During this movement, gas between the circular pressure cap 202 and the raw material will enter through the vent 20201 above the circular pressure cap 202. At this point, the detection module installed in the limit detection frame 203 will detect the gas. If it contains a large amount of carbon dioxide gas produced during fermentation, a signal will be sent to the electrically controlled valve 206. The electrically controlled valve 206 will then open, drawing the gas through the extraction pipe 205 into the gas tank 204 for storage. This gas can be purified and reused later, while also preventing the internal gas pressure of fermenter 2 from increasing and causing damage.

[0036] After fermentation is complete, staff need to remove a portion of the fermented material for use. They open the discharge valve 4 located at the bottom of fermentation tank 2, remove the material, and then close the valve again to seal and store the remaining fermented material. During the material removal process, external gas will inevitably seep in. The entry of external gas into fermentation tank 2 will cause the growth of internal bacteria, thereby reducing the storage period. At this time, the circular pressure cap 202 can be moved down to squeeze the remaining fermented material, thereby pressing the gas present in the fermented material to the top of the circular pressure cap 202, and then drawing it out into the gas tank 204. This can prevent the excessive growth of internal bacteria from shortening the storage period of the remaining fermented material.

[0037] When all the material needs to be removed, the circular pressure cap 202 can be moved down to press the material while the discharge valve 4 is opened, which can improve the discharge efficiency. After the material is pressed, some fermented material will inevitably stick to the circular pressure cap 202. In the existing technology, the circular pressure cap 202 generally needs to be removed and then cleaned by the staff, which is a cumbersome and inefficient process. At this time, the stirring blade 105 can be controlled to approach the circular pressure cap 202. After the first scraper 10501 contacts the circular pressure cap 202, the stirring blade 105 rotates and the first scraper 10501 will scrape off the fermented material sticking to the circular pressure cap 202, thereby improving the cleaning efficiency.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
