Description

Technical Field

[0001] This utility model relates to the field of liquor fermentation technology, and in particular to a solid-state fermentation reaction chamber. Background Technology

[0002] Solid-state fermentation refers to the process of using grains such as sorghum and wheat as raw materials, adding yeast composed of microorganisms such as yeast, mold and bacteria, and converting the starch in the grains into alcohol and flavor substances through saccharification and fermentation.

[0003] Solid-state fermentation is generally carried out in solid-state fermentation tanks for baijiu (Chinese liquor). Fermentation raw materials sprinkled with yeast are placed in the fermentation tank for fermentation. However, conventional fermentation tanks do not have temperature control functions. If the temperature is too low, the activity of microorganisms will be low and their reproduction rate will be slow, resulting in slow saccharification and thus affecting the fermentation process. Furthermore, as fermentation progresses, the temperature of the fermentation system will rise, and if the temperature is too high, it will lead to spoilage and reduce the quality of fermentation.

[0027] The above description of the main component symbols, together with the accompanying drawings and specific embodiments, provides a further detailed explanation of this utility model. Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. Additional aspects and advantages of this utility model will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the utility model. It should be understood that the following description is merely illustrative and not intended to limit the utility model.

[0029] The specific embodiments of this utility model are described in detail below.

[0030] Please see Figure 1-3 This embodiment provides a solid-state fermentation reaction chamber, including a chamber body 1 containing raw materials for baijiu fermentation, a chamber cover 2, a guide pipe 3 fixedly installed on the chamber cover 2, a water pump 4 installed outside the chamber body 1, an enzyme container 11 located inside the chamber body 1, a positioning column 10 fixedly installed through the center of the chamber cover 2, a one-way valve plate 12 installed at the bottom of the enzyme container 11, and a pipeline assembly for connecting the guide pipe 3, the water pump 4 and the positioning column 10.

[0031] The storage cover 2 is detachably mounted on the storage tank 1, and a sealing gasket is wrapped around the storage cover 2. When the storage cover 2 is placed on the storage tank 1, the sealing gasket fills the gap between the storage tank 1 and the storage cover 2. In this embodiment, a rubber sealing gasket is used. On the one hand, it seals the gap between the storage tank 1 and the storage cover 2, creating a sealed solid-state fermentation environment and preventing the loss of aroma. On the other hand, the sealing gasket acts as a damping agent under elastic compression, facilitating the installation and removal of the storage cover 2. That is, the storage cover 2 can be removed simply by applying a certain upward force on both sides of the storage cover 2.

[0032] The guide pipe 3 is located inside the chamber 1. The guide pipe 3 has an inlet pipe, a bend, and an outlet pipe. The bend is a structure of multiple U-shaped pipes connected end-to-end, and it is submerged in the fermentation raw materials. The bend is located between the inlet and outlet pipes, and below the enzyme container 11. Both the inlet and outlet pipes are vertically fixed and pass through the chamber cover 2, with the inlet pipe located on the opposite side of the outlet pipe. A temperature probe is installed on the inner wall of the chamber 1, with its measuring end extending into the fermentation raw materials.

[0033] In this embodiment, the water pump 4 and the guide pipe 3 work together to provide temperature control for the reaction chamber, maintaining the fermentation temperature between 20 and 30°C to prevent spoilage and improve fermentation quality. Temperature control is based on the values ​​detected by a WG22701 temperature probe. Specifically, when the temperature is below 20°C, hot water is introduced into the guide pipe 3; conversely, when the temperature is above 30°C, cold water is introduced. After adjustment, the material is stirred manually to ensure uniform temperature. The curved section is submerged in the liquor fermentation raw materials, establishing a heat conduction control system within them. Compared to directly adding water to the fermentation raw materials, the guide pipe 3 in this embodiment only serves a heat transfer function and has no impact on the fermentation raw materials. Furthermore, the guide pipe 3, fixed to the chamber cover 2, can also act as a stirrer with manual assistance to mix the fermentation raw materials, achieving better fermentation.

[0034] The piping assembly includes a water supply pipe I5 threadedly connected to the inlet pipe, a water supply pipe II6 threadedly connected between the outlet pipe and the inlet of the water pump 4, a tee fitting 7 fixedly installed at the outlet of the water pump 4, and water pipes a8 and b9 mounted on the tee fitting 7. The outlet end of water pipe b9 is threadedly connected to the positioning post 10 and communicates with the channel. Water supply pipes I5, II6, a8, and b9 are all rubber hoses, and water pipes a8 and b9 are each fitted with a water-stop clamp. In this embodiment, the water pipes a8 and b9 can be used flexibly by means of a water stop clamp. When the water stop clamp is on water pipe b9 and the water stop clamp on water pipe a8 is removed, the temperature control function is executed. It should be noted that, under the aforementioned working state, the water delivered along water pipe a8 can be collected in a container for recycling. When the water stop clamp is on water pipe a8 and the water stop clamp on water pipe b9 is removed, the water addition operation after saccharification is executed.

[0035] A channel is formed through the positioning column 10. An enzyme container 11 is screwed onto the end of the positioning column 10. The enzyme container 11 contains lipase, cellulase, and protease. In this embodiment, lipase, cellulase, and protease are added to the solid-state fermentation system based on the enzyme container 11, so that the protein, fat, and cellulose in the raw materials can be rapidly decomposed and transformed into substances that are more easily utilized by microorganisms, thereby promoting the fermentation process. Specifically, cellulase causes the cellulose in the raw materials to be quickly separated into usable nutrients to accelerate the growth and reproduction of yeast. Protease decomposes protein into amino acids so that yeast can use amino acids to produce alcohol, helping the wine to ferment better. Lipase catalyzes the reaction of free organic acids in the mash with ethanol to produce fatty acid esters, making the aroma of the liquor more intense and the taste more mellow.

[0036] A spring is fixedly connected between the corresponding side of the one-way valve plate 12 and the enzyme container 11, and the opening and closing angle range of the one-way valve plate 12 is 0°~45°. In this embodiment, when no water is added, that is, during saccharification, the angle between the one-way valve plate 12 and the enzyme container 11 is 0°. At this time, the enzyme in the enzyme container 11 will not enter the solid-state fermentation system. When water is added after saccharification, the water at a certain flow rate carries the enzyme to open the one-way valve plate 12 and enter the fermentation system. When water is stopped, the one-way valve plate 12 automatically resets under the rebound action of the spring.

[0037] Considering the potential for premature yeast death due to excessively high starch content after grain saccharification, this embodiment employs a structure consisting of water pipe b9, positioning column 10, and enzyme container 11. Water is added without opening the lid, preventing the loss of aroma. Water is added at a grain-to-water ratio of 1:1.2–1.5. This serves two purposes: firstly, diluting the mash to allow for prolonged yeast fermentation; and secondly, introducing enzymes into the fermentation system. It should be noted that the added water is sourced from the water used to cool the fermentation system.

[0038] In summary, the reaction chamber of this embodiment has the following advantages compared with conventional solid-state fermentation tanks for baijiu: it establishes a multi-enzyme synergistic fermentation system, improves the efficiency of raw material decomposition and promotes the release of flavor precursors, and the fermentation temperature is controllable and temperature regulation does not affect the fermentation process, thus improving the fermentation quality.

[0039] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
