[0002] A large amount of distiller's grains will be produced during the production process of liquor brewing. The distiller's grains are rich in nutrients, containing a large amount of crude protein, crude fat, cellulose, vitamins, organic acids, beneficial trace elements and yeast, etc., and can be used as functional feed to feed livestock and poultry.
[0003] However, the distiller's grains produced by brewing are easy to rot, easy to deteriorate, difficult to store, and have poor palatability. Therefore, the distiller's grains produced by brewing cannot be directly used as feed for livestock and poultry. Usually, fresh distiller's grains need to be further processed before they can be fed as feed.
[0004] In the process of processing distiller's grains into feed, the processed distiller's grains need to be subjected to secondary fermentation. The secondary fermentation is usually carried out in a shallow disc. If the amount of distiller's grains to be processed is large, the distiller's grains fermentation will occupy a larger area.

[0028] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.
[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.
[0030] A novel distiller's grains feed production system disclosed in the embodiment of the present application is described in detail in detail. Figure 1 , comprising a screw extruder 1, a drying chamber 2 and a fermentation chamber 3 which are arranged in sequence, wherein the screw extruder 1 is used to separate the solid and liquid of the original distiller's grains, and then the original distiller's grains after solid-liquid separation are dried in the drying chamber 2 to further reduce the moisture content, and finally the dried distiller's grains are placed in the fermentation chamber 3 for secondary fermentation to form feed.
[0031] In a preferred embodiment, referring to Figure 2 The screw extruder 1 is tilted, and the feed port of the screw extruder 1 is higher than the discharge port, and the tilt angle is preferably not less than 15°. According to the above arrangement, on the one hand, the extruded water can flow out from the bottom wall of the screw extruder 1 and be collected, and on the other hand, the original lees is dehydrated under the dual pressure of the pressure of the screw extruder 1 and its own gravity, with a higher dehydration rate and better dehydration effect.
[0032] Further, see Figure 1The screw extruder 1 also includes a liquid discharge port, through which the filtrate after the solid-liquid separation of the original lees by the screw extruder 1 can be discharged. A filtrate drying device 4 is provided at the liquid discharge port, and the water content of the filtrate is reduced and a concentrated liquid is formed by low-temperature evaporation technology, namely, MVR technology. The filtrate drying device 4 is also connected to a condensate collection unit 5 and a concentrated liquid collection unit 6. The concentrated liquid formed during the filtrate drying process enters the concentrated liquid collection unit 6 for collection, and the evaporated liquid enters the condensate collection unit 5.
[0033] Among them, the liquid in the condensate collection unit 5 is subsequently treated by an integrated low-concentration wastewater treatment device, and the UASB+AO+MBR process is used for wastewater treatment. The treated wastewater meets the discharge standards. The methane gas generated during the treatment can be burned in a boiler to produce steam or hot water, which is used to maintain the temperature of the subsequent fermentation chamber 3 for secondary fermentation of the wine lees on the one hand, and on the other hand for use by other heat-requiring units in the factory.
[0034] Further, see Figure 2 The drying chamber 2 is horizontally placed at the discharge port of the screw extruder 1. The drying chamber 2 includes a drying channel 21 and a drying belt 22 arranged in the drying channel 21. The drying belt 22 can be a conveyor belt. The wine lees are transported to the drying belt 22 after being processed by the screw extruder 1 and move along with the drying belt 22. A blasting device is provided on the side wall of the drying channel 21. The blasting device is used to blow air into the drying channel 21 to dry the wine lees. The blasting device is a prior art and will not be described in detail again.
[0035] Among them, the drying channel 21 at least includes a first drying section, a second drying section and a third drying section which are arranged in sequence. The first drying section, the second drying section and the third drying section are respectively controlled by independent control systems, which can control the opening and closing and the ventilation volume independently, so that the drying chamber 2 can control the drying degree of the wine lees by adjusting the running speed of the drying belt 22, the air output of the blowing device, and the number of opened drying sections, so that the wine lees can be dried according to the fermentation requirements.
[0036] Reference Figure 2 The fermentation chamber 3 is arranged at the discharge port of the drying chamber 2, and the fermentation chamber 3 includes a stirring chamber 31 and a screw elevator 32. The lees discharged from the drying chamber 2 first enters the stirring chamber 31 for pretreatment, and then is transported to the screw elevator 32 for secondary fermentation.
[0037] Specifically, refer to Figure 2A plurality of fermentation containers 33 can be placed on the spiral elevator 32. A plurality of card blocks 321 are fixed on the conveyor belt of the spiral elevator 32. At the same time, a card slot is formed at the bottom of each fermentation container 33. By inserting a card block 321 into a card slot of a fermentation container 33, the positions of the fermentation container 33 and the spiral elevator 32 can be relatively fixed, so that the spiral elevator 32 can stably transport the fermentation container 33.
[0038] By providing the spiral elevator 32, multiple fermentation containers 33 can be placed on the spiral elevator 32 for fermentation, thereby increasing the fermentation volume. At the same time, the spiral elevator 32 extends in the height direction and does not occupy much horizontal space, thereby saving space occupied by the wine lees processing site.
[0039] The production staff controls the temperature and humidity inside the spiral elevator 32 so that the environment can meet the fermentation requirements, that is, the lees in all the fermentation containers 33 on the spiral elevator 32 can be fermented; the running speed of the spiral elevator 32 is further controlled so that the fermentation is completed when the fermentation container 33 is transported from the bottom of the spiral elevator 32 to the top of the spiral elevator 32, which is more convenient.
[0040] Furthermore, before the lees enter the spiral elevator 32 for secondary fermentation, materials such as detoxification agents, compound nutrients and fermentation strains need to be added to the lees to meet the fermentation requirements. Adding and mixing materials in the stirring chamber 31 can fully mix the lees and the materials required for fermentation, thereby improving the fermentation quality.
[0041] Reference Figure 2 A lifting platform 311 and a stirring device 7 are provided in the stirring chamber 31, and the lifting platform 311 can be moved from top to bottom to the first position, the second position and the third position to stay; on the other hand, a delivery port 312 is opened on the side wall of the stirring chamber 31, and the fermentation container 33 can be transported from the delivery port 312 to the stirring chamber 31, and the delivery port 312 corresponds to the height surface of the second position, and the discharge port of the drying chamber 2 is also set corresponding to the second position.
[0042] Specifically, refer to Figure 2 After the lifting platform 311 is moved to the second position, the fermentation container 33 is delivered from the delivery port 312 until the fermentation container 33 is located on the lifting platform 311 . At this time, the material discharged from the discharge port of the drying chamber 2 is discharged into the fermentation container 33 .
[0043] Reference Figure 2After the wine lees in the fermentation container 33 are loaded to the set position, the lifting platform 311 can be lifted to the first position, and the stirring device 7 is arranged corresponding to the first position. The stirring device 7 includes a driving source 72, a fixed shaft 73 and a stirring rod 71 arranged in sequence from top to bottom. The driving source 72 is used to drive the stirring rod 71 to rotate. A plurality of feeding pipes 8 are fixed around the fixed shaft 73. Fermentation materials can be added to the fermentation container 33 through the feeding pipes 8. One of the feeding pipes 8 is connected to the concentrated liquid collection unit 6, so that the concentrated liquid can be used as a fermentation material to assist the fermentation of wine lees.
[0044] Reference Figure 2 When the lifting platform 311 is located at the first position, the stirring rod 71 extends into the fermentation container 33 for stirring, and at the same time, the discharge ports of the multiple feeding pipes 8 are located in the fermentation container 33 to reduce the occurrence of splashing out of the fermentation container 33 during the feeding process.
[0045] Reference Figure 2 When the stirring device 7 completes stirring, the lifting platform 311 moves to the third position, which corresponds to the feed port of the spiral elevator 32. A robotic arm is provided at the third position, which can move the fermentation container 33 onto the spiral elevator 32 and plug the card block 321 on the spiral elevator 32 into the card slot of the fermentation container 33. The robotic arm is a prior art and will not be discussed in detail here.
[0046] When the culture dish is moved to the spiral elevator 32, secondary fermentation can be carried out. The novel distiller's grains feed production system of the present application not only reduces the site occupation, but also has fine management throughout the process, facilitates the control of the fermentation environment and distiller's grains treatment, and can improve the fermentation quality.
[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
