[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] See also Figure 1-2 , the utility model provides a technical solution:
[0020] The utility model provides a solid-state fermentation device for producing liquor, comprising: a tank body 1 and a fermentation tank 7. A feed inlet 3 is provided at the top edge of the tank body 1. A water wall 101 surrounds the interior of the tank body 1. A control panel 4 is provided on the exterior of the tank body 1. After the raw pulp enters the tank body 1, the water wall 101 surrounds the interior of the tank body 1 and begins to heat up via the control panel 4, steaming the grains and gelatinizing their starch, facilitating subsequent saccharification and fermentation. The control panel 4 precisely controls the temperature inside the tank body 1 to ensure that the grains are thoroughly cooked but not overly gelatinized.
[0021] Furthermore, a motor 2 is installed at the top center of the tank body 1. The output shaft of the motor 2 is coaxially connected to a stirring paddle 102. The spacing of the stirring blades on the stirring paddle 102 decreases from large to small from top to bottom to accommodate the stirring of materials of different densities. When the raw pulp is added, the solids settle to the bottom of the tank body 1. The tight stirring blades at the bottom can better crush large particles of solids, while squeezing smaller solids to flow upward, allowing the stirring blades above to stir them a second time. During the next process, a saccharification and fermentation agent is added from the feed port 3 to convert starch into fermentable sugars. At the same time, the temperature, humidity and time of saccharification are strictly controlled by the control panel.
[0022] Furthermore, the bottom of the tank body 1 is connected to a filter chamber 6, and a first closed baffle 601 is inserted between the tank body 1 and the filter chamber 6. When the raw pulp in the tank body 1 is crushed, the first baffle 601 is removed, allowing the raw pulp to flow into the filter chamber 6. The raw pulp flowing into the tank body 1 passes through the first filter 604 and the second filter 605 in sequence. The first filter 601 is made of bamboo and can filter larger solids. The second filter 602 is a tightly packed composite mesh that can filter small sediments. The mesh size of the lower filter is smaller than that of the upper filter. After the raw pulp is stirred and crushed, it passes through two layers of filter screens and can be filtered into raw pulp of different concentrations. After the filtration is completed, the second closed baffle 602 and the third closed baffle 603 are inserted in sequence to ensure that the concentration of the raw pulp in each layer is not mixed. It is also possible to replace the filter screens of different materials and sizes according to the different raw pulp to produce a variety of flavors of liquor.
[0023] Furthermore, a water pump 5 connects the filtration chamber 6 to the fermentation tank 7 via a first pipe 8, a second pipe 9, and a third pipe 10. The bottom of the fermentation tank 7 is equipped with a base 701, which increases its height and stability. A discharge pipe 702 is located on the side. Each of the three pipes connected to the water pump 5 has an independent control button. The first pipe 8 extracts the crushed raw pulp, the second pipe 9 extracts the raw pulp after filtering through the first filter 601, and the third pipe 10 extracts the raw pulp after filtering through the second filter 602. By operating the water pump buttons, the raw pulp ratio in the fermentation tank 7 can be controlled, enriching the microbial species during the fermentation process and adding a richer taste to the baijiu. Finally, the raw pulp is allowed to rest in the fermentation tank 7, and the valve 703 on the discharge pipe 702 is opened, delivering it to the discharge tank 11. By optimizing the brewing equipment and adopting a novel heating and cooling system, the brewing cycle can be significantly shortened and the yield can be increased. Advanced filtering devices can filter out and absorb foreign and unpleasant odors in the baijiu, enhancing the taste. Furthermore, variable control can be used to brew baijiu with different flavors.
[0024] The crushing efficiency is improved, the raw material temperature and the liquid-solid ratio in the fermentation tank can be effectively controlled, the saccharification efficiency is increased, and the wine quality of the entire cellar is improved.
[0025] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
