Description

Technical Field

[0001] The present application relates to the field of food fermentation, and in particular to a fermentation device for making hot seeds. Background Art

[0002] In the fermented food industry, especially in the production of bread, steamed buns and other pasta products, hot seed, as an important yeast fermentation starter, plays a vital role in product quality. The fermentation tank is the main equipment for hot seed fermentation. The fermentation tank transfers the heat of the steam layer on the tank wall to the hot seed inside by contact heat transfer to heat the hot seed, and then uses a stirring paddle to rotate and stir to meet the temperature requirements for hot seed cultivation.

[0003] In the actual production process, in order to increase the cultivation amount of the hot seeds in a single fermentation tank, it is usually necessary to increase the diameter of the fermentation tank to increase the volume of the fermentation tank. As the volume increases, the hot seeds in the middle of the fermentation tank are heated unevenly. Although the stirring paddle can stir the hot seeds, due to the large amount of hot seeds in the fermentation tank, it is still difficult to achieve uniform heating. Therefore, there is still room for improvement. Summary of the invention

[0005] The present application provides a fermentation device for making hot seeds using the following technical solution: A fermentation device for making scalded seeds, comprising a tank body for accommodating scalded seeds, a heating component located outside the tank body, a stirring shaft connected to the tank body for vertical rotation, stirring rods radially arranged on the outer periphery of the stirring shaft, and a driving member for driving the stirring rods to rotate, the tank wall of the tank body is provided with an interlayer, the heating component is used to pass a heating medium into the interlayer, a through pipe is provided between the stirring shaft and a plurality of stirring rods, one end of the through pipe is connected to the interior of the interlayer, and the other end of the through pipe passes through the interior of the stirring shaft and the interior of a plurality of stirring rods and passes out of the tank body.

[0006] By adopting the above technical scheme, the stirring shaft and the stirring rod are connected by a through pipe, and one end of the through pipe is connected to the inside of the tank wall interlayer of the stirring tank, and the other end is connected to the outside of the tank body. When the heating component introduces the heating medium into the interlayer of the stirring tank, the heating medium fills the entire interlayer and flows through the stirring shaft and a plurality of stirring rods through the through pipe. The interlayer heats the hot seeds on the inner and outer sides of the tank body, and the stirring shaft and the stirring rod heat the hot seeds at the center axis position of the tank body.

In addition, the interlayers are distributed in the tank bottom structure and the tank wall structure and are interconnected, wherein the serpentine tube is connected to the interlayer at the tank wall structure, and the through pipe is connected to the interlayer at the tank bottom structure, which is beneficial for the flow channel of the heating medium to be connected after the tank body is assembled, and is beneficial for the stable flow of the heating medium.

[0017] Preferably, a heat supply inlet connected to the heating component is provided outside the tank body, and the end of the serpentine tube located outside the tank body and the end of the through pipe located outside the tank body are both connected to the heating component. The heating component passes the heating medium into the interlayer through the heat supply inlet, and the heating medium in the interlayer is discharged from the tank body through the serpentine tube and the through pipe and refluxes into the heating component.

[0018] By adopting the above technical solution, the heating inlet is used as the inlet for the heating medium to enter the interlayer, and the through pipe and one end of the serpentine pipe outside the tank body are used as the outlet for the heating medium to discharge out of the tank body and are connected to the heating component, thereby forming a circulating heating pipeline, realizing the recycling of heat energy, and helping to reduce energy consumption.

When the stirring rod 6 is installed to the corresponding position of the stirring shaft 5, the through pipe 7 at the stirring rod 6 is docked and connected with the through pipe 7 inside the stirring rod 6. The lower end of the through pipe 7 at the stirring shaft 5 extends to the inside of the interlayer 3 at the tank bottom structure 21, thereby achieving communication with the inside of the interlayer 3. The upper end of the stirring shaft 5 and the upper end of the through pipe 7 inside the stirring shaft 5 both penetrate the tank top structure 23, so that the through pipe 7 is connected to the outside of the tank body 2.
