Description

Technical Field

[0001] This utility model relates to the field of acetic acid processing technology, specifically an integrated acetic acid fumigation machine. Background Technology

[0002] Solid-state fermented vinegar involves a wider variety of microorganisms, resulting in a better flavor and the production of more health-beneficial substances such as ligustrazine, flavonoids, and organic acids. Therefore, solid-state fermented vinegar is becoming increasingly popular.

[0003] In the traditional solid-state vinegar brewing industry, the three processes of fermentation, fumigation, and vinegar extraction are completed using separate equipment: fermentation tanks, fumigation tanks, and vinegar extraction tanks, respectively. Conveying equipment is required between these three stages, increasing the possibility of contamination during transport and causing significant evaporation and waste of acetic acid. To address these issues, integrated fumigation and extraction machines have been developed. However, existing machines primarily rely on stirring to agitate the raw materials, resulting in poor fermentation uniformity. Furthermore, when draining the vinegar after extraction, the vinegar residue easily clogs the filter plates, hindering the smooth flow of the vinegar. Improvements are needed. Utility Model Content

[0004] The technical problem this invention aims to solve is that the existing acetic acid fumigation and rinsing integrated machine has poor uniformity of vinegar mash fermentation, and the vinegar residue is very easy to clog the filter plate, resulting in poor vinegar discharge.

[0005] To solve the above problems, the technical solution of this utility model is as follows: an integrated acetic acid fumigation machine, including a frame, a tank body rotatably mounted on the top of the frame, the tank body being a horizontal cylindrical shape with an inner cylinder inside, a material inlet / outlet at the top, a liquid outlet at the bottom, and a manhole at the right end, a sealing cap at the material inlet / outlet, and an end cap at the manhole, a cavity between the inner cylinder and the tank body, with an inlet pipe and a return pipe respectively at both ends of the cavity, a spray pipe penetrating the left end of the tank body, the spray pipe extending to the right end of the inner cylinder, and having several spray holes on its surface, multiple sets of guide strips fixed to the inner wall of the inner cylinder, each set of guide strips being arranged in a figure-eight shape, a filter cylinder installed in the liquid outlet, the top of the filter cylinder located inside the inner cylinder, the bottom extending to the outside of the tank body, a liquid outlet pipe at the bottom of the filter cylinder, a rotating shaft penetrating through the middle, a scraper mounted on the top of the rotating shaft, and a handwheel mounted on the bottom.

[0006] Furthermore, support roller tracks are installed on the outer sides of both ends of the tank, and support rollers for supporting the tank are installed on the frame. An external gear ring is also installed on the outer side of one end of the tank, and a motor is installed on the frame. A gear that meshes with the external gear ring is installed on the output shaft of the motor.

[0007] Furthermore, the centerlines of both the inlet pipe and the return pipe coincide with the centerline of the tank.

[0008] Furthermore, a positioning plate for fixing the spray pipe is installed inside the right end of the inner cylinder.

[0009] Furthermore, the filter cylinder is formed by welding a small cylinder and a large cylinder together, and filter holes are provided on the top surface and upper side surface of the small cylinder.

[0010] Furthermore, the scraper has an L-shaped structure and is attached to the outer surface of the filter cartridge.

[0011] Furthermore, solenoid valves are installed on the inlet pipe and the return pipe, and a valve is installed on the drain pipe.

[0012] The advantages of this invention compared to existing technologies are as follows: This invention uses the forward and reverse rotation of the motor in conjunction with the guide strip to achieve the reciprocating tumbling of materials inside the tank, thereby improving the uniformity of vinegar mash fermentation; by rotating the shaft with the handwheel, the shaft drives the scraper to rotate, which can prevent vinegar residue from clogging the surface of the filter cylinder and ensure smooth discharge of vinegar liquid.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 3 As shown, an integrated acetic acid fumigation machine includes a frame 1, a tank 2 rotatably mounted on the top of the frame 1, the tank 2 being a horizontal cylindrical shape with an inner cylinder 3 inside, a material inlet / outlet at the top, a liquid outlet at the bottom, a manhole at the right end, a sealing cap 4 at the material inlet / outlet, and an end cap 5 at the manhole. Support roller tracks 15 are mounted on the outer sides of both ends of the tank 2, and support rollers 16 for supporting the tank 2 are mounted on the frame 1. An external gear ring 17 is also mounted on the outer side of one end of the tank 2. A motor 18 is mounted on the frame 1, and a gear 19 meshing with the external gear ring 17 is mounted on the output shaft of the motor 18. Multiple sets of guide strips 9 are fixedly connected to the inner wall of the inner cylinder 3, each set of guide strips 9 being arranged in a V-shape.

[0021] The motor 18 drives the outer gear ring 17 and the tank 2 to rotate through the gear 19. When the motor 18 rotates in the forward direction, the vinegar mash can move towards the middle of the inner cylinder 3 under the action of the guide bar 9. When the motor 18 rotates in the reverse direction, the vinegar mash can move towards both ends of the inner cylinder 3 under the action of the guide bar 9. This can realize the reciprocating turning of the material inside the tank 2 and improve the uniformity of the vinegar mash fermentation.

[0022] A cavity is provided between the inner cylinder 3 and the tank body 2. Several connecting blocks are provided inside the cavity, which are connected to the outer wall of the inner cylinder 3 and the inner wall of the tank body 2. An inlet pipe 6 and a return pipe 7 are provided at both ends of the cavity. The center lines of the inlet pipe 6 and the return pipe 7 coincide with the center line of the tank body 2. A drain pipe is also provided at the bottom of the cavity.

[0023] The inlet pipe 6 and the return pipe 7 are connected to an external steam heating system via a rotary joint. The inner cylinder 3 is heated by steam, thereby enabling the fermentation of the vinegar mash.

[0024] like Figures 3 to 5As shown, a spray pipe 8 is installed through the left end of the tank body 2. The spray pipe 8 extends to the right end of the inner cylinder 3, and the surface of the spray pipe 8 is provided with several spray holes. A positioning plate 20 for fixing the spray pipe 8 is installed inside the right end of the inner cylinder 3. A filter cylinder 10 is installed in the drain port. The filter cylinder 10 is formed by welding a small cylinder and a large cylinder. Filter holes are opened on the top surface and upper side of the small cylinder. The top of the filter cylinder 10 is located inside the inner cylinder 3, and the bottom extends to the outside of the tank body 2. A drain pipe 11 is provided at the bottom of the filter cylinder 10. A rotating shaft 12 is installed through the middle. A scraper 13 is installed on the top of the rotating shaft 12, and a handwheel 14 is installed on the bottom. The scraper 13 has an L-shaped structure and is attached to the outer surface of the filter cylinder 10.

[0025] After the fermentation process is complete, rotate the drain port to the bottom of tank 1 and connect the spray pipe 8 to the water supply pipe to perform vinegar rinsing. Open the valve on the drain pipe 11 to drain the vinegar. Rotate the shaft 12 via handwheel 14. The shaft 12 drives the scraper 13 to rotate, preventing vinegar residue from clogging the surface of the filter cylinder 10 and ensuring smooth vinegar discharge. After the vinegar is discharged, rotate the inlet and outlet ports to the bottom of tank 1 and open the sealing cover 4 to drain the vinegar residue.

[0026] In practical use, temperature and pressure sensors and humidity sensors are installed in the inner cylinder 3 to monitor the environment inside the inner cylinder 3. The device is connected to the PLC control system. After the raw materials undergo pre-treatment such as crushing, moistening, liquefaction, saccharification, and alcoholic fermentation, they enter the mixing stage. The mixed material is then added to the tank 1 for acetic acid fermentation. During this process, the PLC control system uses the data monitored by the sensors to link the rotation and start / stop of the tank 2, achieving automated control. The inlet pipe 6 and return pipe 7 are connected to the external steam heating system through a rotary joint. The inner cylinder 3 is heated by steam, thereby achieving the smoking of the vinegar mash. The spray pipe 8 is connected to the water supply pipe to perform vinegar rinsing. Opening the valve on the drain pipe 11 allows the vinegar to be discharged. The handwheel 14 rotates the shaft 12, which drives the scraper 13 to rotate, preventing the vinegar residue from clogging the surface of the filter cylinder 10 and ensuring smooth discharge of the vinegar liquid. After the vinegar liquid is discharged, the motor 18 rotates in the forward direction to move the vinegar residue to the middle of the inner cylinder 3, and then the discharge port is rotated to the bottom of the tank body 1. The sealing cover 4 can be opened to discharge the vinegar residue.
