[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0039] In view of the problems mentioned in the above background technology, the embodiment of the utility model provides a yeast solid fermentation reactor to solve the above technical problems, and its technical solution is as follows:

[0040] A yeast solid fermentation reactor, comprising: a tank body 110, a discharging conveyor 130 and a fermentation liquid circulation spraying mechanism;

[0041] The discharge conveyor 130 is located at the bottom of the tank body 110, and the discharge port of the tank body 110 is connected to the top surface of the discharge conveyor 130;

[0042] The fermentation liquid circulation spraying mechanism includes a container 121, a circulation pump 122, a main pipeline 123, and a spray branch pipe 124; the container 121 is used to store the circulating fermentation liquid;

[0043] The container 121 is located at the bottom of the tank body 110 and is connected to the bottom surface of the body of the discharge conveyor 130 through a pipeline;

[0044] The spray branch pipe 124 is located in the tank body 110 and fixed to the top wall of the tank body 110. The bottom surface of the spray branch pipe 124 is provided with a plurality of fermentation liquid nozzles.

[0045] One end of the main pipeline 123 is connected to the bottom of the container 121 , and the other end extends upward into the tank body 110 and is connected to the spray branch pipe 124 ; the circulation pump 122 is connected in series to the main pipeline 123 .

[0046] After the material pre-treated by the front-end process is sent to the tank body 110 through the feeding equipment, during the fermentation process, the circulation pump 122 works to send the fermentation liquid in the container 121 to the spray branch pipe 124, and sprays it onto the surface of the material from the fermentation liquid nozzle on the spray branch pipe 124. The fermentation liquid gradually penetrates into the lower material from top to bottom, and flows out from the bottom of the tank body 110 and is recovered to the container 121 for the next circulation. The purpose of setting up the fermentation liquid circulation spraying mechanism is to recycle the yeast and reduce the temperature of the material in the tank.

[0047] It should be noted that, when necessary, the fermentation liquid can be heated or cooled in the container 121 so as to better adjust the material temperature through the circulation of the fermentation liquid.

[0048] In this embodiment, the upper part of the tank body 110 is a straight cylindrical structure, and the lower part is a conical structure; the discharge port of the tank body 110 is located at the bottom of the conical structure; the conical structure can be a single cone or multiple cones, and the multiple cones can be double cones, triple cones, quad cones, etc.; to prevent corrosion of materials, the tank wall is generally made of stainless steel plates or stainless steel composite steel plates, and other corrosion-resistant or thicker materials can also be used.

[0049] In this embodiment, a material distribution mechanism 140 is also included, and the material distribution mechanism 140 includes a reduction motor 141, a bearing seat 142, a main shaft 143 and a material distribution blade 144;

[0050] The bearing seat 142 is fixed to the top of the tank body 110;

[0051] The reduction motor 141 is arranged on the tank body 110, and the motor shaft of the reduction motor 141 is arranged to rotate vertically through the bearing seat 142;

[0053] The material distribution blade 144 is fixed on the main shaft 143; specifically, the material distribution blade 144 is in an arc-shaped scimitar shape.

[0054] After the material is delivered to the tank body 110 by the feeding equipment, the reduction motor 141 provides power and transmits it to the material leveling blade 144 through the shaft. The material leveling blade 144 rotates horizontally, and the material piled below the feed inlet is pushed to the lower material level during the rotation of the material leveling blade 144, finally achieving a relatively uniform material level.

[0055] In this embodiment, a gas explosion device is also included, which includes a central gas explosion mechanism 150 and a peripheral ring tube gas explosion mechanism 160; the central gas explosion mechanism 150 is located at the center position inside the tank body 110, and the peripheral ring tube gas explosion mechanism 160 is located inside the tank body 110 and is arranged around the central gas explosion mechanism 150.

[0056] The aeration device can provide a good aerobic environment for the fermentation of wine lees, and the evaporation of water will be accelerated during the aeration process, which plays a role in controlling the temperature and humidity of the material. At the same time, the aeration device not only supplies oxygen to the material when necessary, but also can be used to fluff up and break the arch and push the material downward during discharging, so as to avoid arching and reduce dead corners.

[0057] In this embodiment, the central aeration mechanism 150 includes a hollow shaft 151, a jacket layer 152 arranged on the outside of the hollow shaft 151, an aeration layer 153 located between the hollow shaft 151 and the jacket layer 152, and a central branch pipe 154 connected to the aeration layer 153 and extending to the outside of the jacket layer 152. A central nozzle 156 is arranged on the central branch pipe 154, and the central branch pipe 154 is preferably arranged to be inclined downward; a control valve is arranged between the central branch pipe 154 and the central nozzle 156.

When the temperature is low in winter, the material in the center of the tank can be heated up, and when the temperature is high, the material in the center of the tank can be cooled down.

[0059] In this embodiment, the peripheral annular tube explosion mechanism 160 includes an annular tube 161 arranged around the central explosion mechanism 150, a peripheral branch tube 162 connected to the annular tube 161, and a peripheral nozzle 164 arranged on the peripheral branch tube 162; a control valve 163 is arranged between the peripheral branch tube 162 and the peripheral nozzle 164.

[0064] The heat transfer medium is water or heat-conducting oil. When the temperature is low in winter, it can heat up the material in the tank. When the temperature is high, it can cool down the material in the tank, thereby regulating the temperature of the material.

[0065] In this embodiment, the discharge conveyor 130 is a screw conveyor, and a gate valve 131 is provided on the bottom surface of the screw conveyor body. The outlet of the gate valve 131 is connected to the container 121 through a pipeline; the screw conveyor preferably adopts a shafted double-screw conveying structure, and a single screw and a shaftless screw can also be considered. The screw conveyor conveys the reacted material out of the reactor and then enters the subsequent process equipment.

[0066] In this embodiment, a temperature sensor or an electronic thermometer is provided in the tank body 110; a material level meter is provided at the top of the tank body 110. The position and quantity of the temperature sensor or the electronic thermometer can be selected according to the needs, and the material level meter is preferably a radar or ultrasonic material level meter; the temperature sensor or the electronic thermometer and the material level meter are used to monitor the temperature and material level of the material.
