Abstract
Description
Technical Field
[0001] This utility model relates to the field of fermentation technology, and in particular to a small-scale fermentation tank. Background Technology
[0002] Small-scale fermentation equipment is a necessary condition for carrying out fermentation product research and development and pilot-scale experiments. However, because the fermentation process is relatively complex, including multiple steps such as enzymatic hydrolysis, fermentation, and sterilization, a complete fermentation system requires a lot of auxiliary facilities and equipment.
[0003] Currently, small-scale fermentation equipment requires the discharge of the solid-liquid mixture after fermentation, followed by separation, which involves a large amount of work. Utility Model Content
[0004] The purpose of this invention is to provide a small-scale fermentation tank to alleviate the technical problem of the large workload involved in discharging and separating the solid-liquid mixture after fermentation.
[0005] This utility model provides a small-scale fermentation tank, including a fermentation tank body, and a fermentation chamber is provided inside the fermentation tank body; a discharge pipe is provided at the lower end of the fermentation tank body, and the discharge pipe is connected to the fermentation chamber;
[0006] A first discharge pipe is provided on the side wall of the main body of the fermentation tank, and one end of the first discharge pipe is connected to the fermentation chamber, and the other end is connected to the discharge pipe.
[0007] In an optional embodiment, the fermenter body has a jacket, and a first injection pipe communicating with the jacket is provided on the fermenter body.
[0008] In an optional embodiment, a first discharge pipe is provided at the lower end of the fermenter body, and the first discharge pipe is connected to the jacket.
[0009] In an optional embodiment, a fermentation tank cover is bolted to the upper end of the fermentation tank body; a drive motor is provided at the upper end of the fermentation tank cover; and a stirring rod is provided inside the fermentation tank body, extending from the upper end of the fermentation tank cover and connected to the drive motor.
[0010] In an optional embodiment, the fermenter lid is provided with a first injection port, which is used for injecting raw materials.
[0011] In an optional embodiment, the fermenter lid is provided with an observation port.
[0012] In an optional embodiment, the fermenter lid is provided with a light-filling port.
[0013] In an optional embodiment, a level gauge is provided on one side of the fermenter body, with one end of the level gauge connected to the upper end of the fermenter body and the other end connected to the discharge pipe.
[0014] The small-scale fermenter provided by this utility model has a first discharge pipe on its main body. One end of the first discharge pipe is connected to the fermentation chamber, and the other end is connected to the discharge pipe. After fermentation is completed in the main body of the fermenter, the fermentation liquid in the main body of the fermenter is discharged through the first discharge pipe. This can reduce the amount of liquid in the main body of the fermenter. After most of the liquid in the main body of the fermenter is discharged, the solid-liquid mixture in the fermenter is discharged from the discharge pipe. This can reduce the amount of solid-liquid mixture to be processed and improve the processing efficiency. Attached Figure Description

[0023] Example
[0024] Reference Figure 1 This utility model provides a small-scale fermentation tank, including a fermentation tank body 100, and a fermentation chamber 300 is provided inside the fermentation tank body 100; a discharge pipe 600 is provided at the lower end of the fermentation tank body 100, and the discharge pipe 600 is connected to the fermentation chamber 300.
[0025] A first discharge pipe 140 is provided on the side wall of the fermentation tank body 100, and one end of the first discharge pipe 140 is connected to the fermentation chamber 300, and the other end is connected to the discharge pipe 600.
[0026] In some embodiments, one end of the first discharge pipe 140 provided on the fermenter body 100 of the pilot fermenter is connected to the fermentation chamber 300, and the other end is connected to the discharge pipe 600. Since the volume of the fermenter body 100 is fixed, the amount of raw materials to be added is fixed. That is, after the raw materials are fermented, the height of the solid is within a certain range, and the connection between the first discharge pipe 140 and the fermentation chamber 300 is located above the solid. When it is necessary to discharge the liquid in the fermenter body 100, most of the liquid in the fermenter body 100 is discharged through the first discharge pipe 140. The liquid discharged from the first discharge pipe 140 does not need to be filtered or otherwise processed.
[0027] The solid-liquid mixture in the fermentation chamber 300 is discharged from the discharge pipe 600, and the solid-liquid mixture discharged from the discharge pipe 600 is then processed. Since most of the liquid is discharged from the first discharge pipe 140, the amount of solid-liquid mixture that needs to be processed is reduced, and the processing efficiency is improved.
[0028] In an optional embodiment, the fermenter body 100 has a jacket 200, and a first injection pipe 400 communicating with the jacket 200 is provided on the fermenter body 100.
[0029] In an optional embodiment, a first discharge pipe 500 is provided at the lower end of the fermenter body 100, and the first discharge pipe 500 is connected to the jacket 200.
[0030] In some embodiments, the fermentation tube body has a jacket 200, and a first injection pipe 400 and a first discharge pipe 500 are provided on the fermentation tank body 100. The height of the first injection pipe 400 is higher than that of the first discharge pipe 500, and the connection between the first discharge pipe 500 and the jacket 200 is located at the lowest end of the jacket 200.
[0031] The first injection pipe 400 is used to inject water into the jacket 200, and the first discharge pipe 500 is used to discharge the water from the jacket 200. An electric heating system and a temperature control system are provided on the fermentation tank body 100. The temperature of the raw materials in the fermentation chamber 300 is controlled by the electric heating system and the temperature control system so that they can ferment within a suitable temperature range.
[0032] When it is necessary to lower the temperature inside the fermenter, the water inside the jacket 200 is discharged through the first discharge pipe 500, and cold water is added through the first injection pipe 400 to regulate the temperature of the water inside the jacket.
[0033] In an optional embodiment, a fermentation tank cover 700 is bolted to the upper end of the fermentation tank body 100; a drive motor 120 is provided at the upper end of the fermentation tank cover 700; and a stirring rod 130 is provided inside the fermentation tank body 100, the stirring rod 130 extending from the upper end of the fermentation tank cover 700 and connected to the drive motor 120.
[0034] In an optional embodiment, the fermenter cover 700 is provided with a first injection port 800, which is used for injecting raw materials.
[0035] In an optional embodiment, the fermenter lid 700 is provided with an observation port 900.
[0036] In an optional embodiment, the fermenter lid 700 is provided with a supplementary light port 110.
[0037] In an optional embodiment, a level gauge 150 is provided on one side of the fermenter body 100. One end of the level gauge 150 is connected to the upper end of the fermenter body 100, and the other end is connected to the discharge pipe 600.
[0038] In some embodiments, a fermentation tank cover 700 is provided at the upper end of the fermentation tank body 100. The fermentation tank cover 700 is detachably connected to the fermentation tank body 100. Generally, the fermentation tank cover 700 is fixed to the fermentation tank body 100 by bolts.
[0039] The fermentation tank cover 700 is provided with a first injection port 800, an observation port 900 and a supplementary light port 110; the raw material is added into the fermentation tank body 100 from the first main inlet, the interior of the fermentation tank body 100 is illuminated by the supplementary light port 110 and observed through the observation port 900.
[0040] A transparent glass plate is installed at the observation port 900, through which the condition inside the fermentation tank body 100 can be observed.
[0041] The level gauge 150 is used to determine the liquid level inside the fermenter body 100. One end of the level gauge 150 is connected to the discharge pipe 600, and the other end is connected to the upper end of the fermenter body 100. The liquid inside the fermenter body 100 enters the level gauge 150 from the discharge pipe 600, and the height of the liquid in the level gauge 150 is the same as the liquid level inside the fermenter body 100.
[0042] During fruit juice fermentation, raw materials are injected through the first injection port 800. During enzymatic hydrolysis, water or oil is injected through the first injection pipe 400. The water or oil is heated by an electric heating system, and the internal temperature is controlled by a built-in temperature probe and an external temperature control system to provide suitable temperature conditions for enzymatic hydrolysis. Simultaneously, the drive motor 120 is activated during enzymatic hydrolysis, causing the stirring rod 130 to rotate. After enzymatic hydrolysis, the electric heating system continues to operate, and the temperature control system further raises the temperature to achieve enzyme inactivation and initial sterilization of the raw materials.
[0043] Before fermentation, hot water in jacket 200 is discharged through first discharge pipe 500 and flowing cold water is injected through first injection pipe 400. At the same time, stirring is turned on to make the liquid temperature in fermentation tank body 100 drop rapidly.
[0044] After the temperature drops, the temperature is controlled to the fermentation temperature by the temperature control system. The inoculum is then introduced through the first inlet 800. Stirring is started to ensure even distribution of the inoculum, then stopped. The temperature maintenance system remains on and maintains the temperature. During fermentation, the supplemental lighting port 110 can be opened to illuminate the interior of the fermentation tank 100, and observation can be conducted through the observation port 900. After fermentation, the temperature is controlled to the sterilization temperature by the temperature control system, and stirring is activated to sterilize the fermented product.
[0045] During fruit wine fermentation (requiring enzymatic hydrolysis): Raw materials are injected through the first injection port 800. During enzymatic hydrolysis, water or oil is injected through the first injection pipe 400. The water or oil is heated by an electric heating system, and the internal temperature is controlled by a built-in temperature probe and an external temperature control system to provide suitable temperature conditions for enzymatic hydrolysis. The stirring system is activated simultaneously during enzymatic hydrolysis. After enzymatic hydrolysis and before fermentation, hot water in the jacket 200 is drained through the first discharge pipe 500, and flowing cold water is injected through the first injection pipe 400. Simultaneously, the stirring is activated to rapidly lower the liquid temperature in the fermentation tank. Once the temperature has dropped, the temperature is controlled to the fermentation temperature by the temperature control system. Inoculum, sugar, and sulfur are then added through the first injection port 800. Stirring is activated to ensure even distribution of the inoculum, then stopped. The temperature control system remains on to maintain the temperature. During fermentation, the supplemental lighting port 110 can be opened to illuminate the interior of the fermentation tank 100, and observation can be performed through the observation port 900. After fermentation, the product is discharged through the first discharge pipe 140.
[0046] The small-scale fermenter provided by this utility model has a first discharge pipe 140 on the fermenter body 100. One end of the first discharge pipe 140 is connected to the fermentation chamber 300, and the other end is connected to the discharge pipe 600. After fermentation is completed in the fermenter body 100, the fermentation liquid in the fermenter body 100 is discharged through the first discharge pipe 140. This can reduce the amount of liquid in the fermenter body 100. After most of the liquid in the fermenter body 100 is discharged, the solid-liquid mixture in the fermenter is discharged from the discharge pipe 600. This can reduce the amount of solid-liquid mixture to be processed and improve the processing efficiency.
