Description

Technical Field

[0001] The invention belongs to the technical field of liquor brewing, and relates to a system device for steaming raw materials for brewing liquor. Background Art

[0002] In the winemaking process, the cooking of raw materials is a key link. In the traditional winemaking process, natural cooling is usually used to cool down the raw materials after cooking. This method is slow and time-consuming, which seriously affects production efficiency. At the same time, a large amount of heat generated during the cooking process is wasted and cannot be effectively recycled, resulting in a huge waste of energy.

[0003] With the continuous development of the brewing industry, the requirements for production efficiency and energy utilization are getting higher and higher. The traditional cooling method and heat waste problem have become the bottleneck restricting the development of the brewing industry.

[0004] The prior art scheme discloses a process for refining fine liquor, including raw material and auxiliary material proportioning, raw material and auxiliary material crushing, a steaming and moistening process, a grain steaming and fermentation process and a negative pressure condensation process. The liquor can be made by adopting negative pressure condensation, the air pressure of the system is controlled by a vacuum pump, and negative pressure distillation is adopted at room temperature to avoid the destruction of volatile flavor substances by high temperature, thereby increasing the alcohol content of the original liquor, reducing the loss of flavor components, and improving the flavor of the liquor.

[0005] However, the existing technology still has problems such as the inability to recycle heat, waste of water resources, the presence of impurity gases, and a certain impact on the quality of brewed products. Therefore, it is urgent to design a system device for steaming brewing raw materials to overcome the defects of the existing technology and meet practical application needs. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a system device for cooking brewing raw materials. In the present invention, a system device for rapid cooling and heat recovery based on vacuum extraction during the cooking of brewing raw materials is designed, and vacuum extraction technology is utilized to achieve efficient cooling during the cooking of brewing raw materials, and heat and steam resources are recycled and utilized, thereby saving water resources and improving the efficiency of brewing production and the level of energy utilization.

[0007] To achieve this object, the present invention adopts the following technical solutions:

[0008] The present invention provides a system device for steaming raw materials for brewing wine, the system device comprising a steamer, the steamer is provided with a steam outlet, the steamer is connected to a vacuum extraction device and a heat recovery device in sequence through pipelines via the steam outlet; the liquid inlet end of the heat recovery device is connected to a circulating water return buffer tank through a pipeline, and the gas outlet end of the heat recovery device is connected to a steam exhaust treatment device through a pipeline.

[0009] In the present invention, by designing a system device for rapid cooling and heat recovery based on vacuum extraction during the cooking process of brewing raw materials, vacuum extraction technology is used to achieve efficient cooling during the cooking process of brewing raw materials, and heat and steam resources are recycled and utilized, thereby saving water resources and improving the efficiency of brewing production and the level of energy utilization.

[0010] It should be noted that the present invention does not specifically limit the specific structures and models of the steam retort, vacuum extraction device, heat recovery device, circulating water return buffer tank and exhaust steam treatment device, and those skilled in the art can make adaptive adjustments according to actual conditions.

[0011] It should be noted that in the present invention, after the brewing raw materials are steamed, the vacuum extraction device quickly reduces the pressure in the steamer by generating negative pressure, so that the materials in the steamer can be cooled quickly, greatly shortening the production cycle; compared with the traditional natural cooling method, vacuum extraction can reduce the temperature to an appropriate range in a shorter time, thereby improving production efficiency; the heat recovery device recovers the heat and condensed water released during the cooling of the hot steam, which are used in other production links or provided to other equipment requiring heat sources, thereby realizing efficient use of energy; when the system recovers heat, the recovered hot water or steam condensed water needs to have a stable storage The circulating return water buffer tank receives and stores the return water, which plays a role in buffering water flow fluctuations and ensuring the stability of the system operation. According to the needs of the system, the return water can be transported to the required place at a relatively stable pressure and flow rate, such as for preheating brewing raw materials, cleaning equipment, etc., thereby improving the overall efficiency of the system and ensuring the normal operation of each link. In the process of return water, some impurities and sediments may be carried. The return water buffer tank plays a certain separation role, so that the impurities are settled at the bottom of the tank, which is convenient for regular cleaning and discharge. This helps to protect other equipment in the system and prevent impurities from damaging it or affecting its performance.

[0012] As a preferred technical solution of the present invention, the system device also includes a control device, and the steam retort, the vacuum extraction device, the heat recovery device, the circulating water return buffer tank and the exhaust steam treatment device are respectively connected to the control device by wireless connection or wired connection.

[0013] It should be noted that the control device, as the trusted operation of the entire system device, can be in the form of a computer terminal, which can monitor and adjust the entire system in real time according to preset parameters, coordinate the operation of various devices, ensure that they can work together according to the predetermined procedures, and ensure the stable operation and efficient operation of the system. The control device can accurately adjust the operating parameters of the vacuum pump, such as vacuum speed, pressure, etc., to achieve precise control of the pressure in the steamer, which is crucial to the rapid cooling process and ensures that the material can reach the required temperature within the appropriate time.

[0014] As a preferred technical solution of the present invention, the vacuum extraction device includes a vacuum pump, and the vacuum pump is used to extract the steam in the steamer.

[0016] It should be noted that the extraction power of the vacuum pump in the present invention is 7.5kW to 8kW because it meets the process standards within this range and does not cause waste of resources; if the extraction power is too large, it will cause waste of resources, and if the extraction power is too small, steam cannot be effectively extracted.

[0017] As a preferred technical solution of the present invention, the heat recovery device includes a condenser, the liquid inlet end of the condenser is connected to the liquid outlet end of the circulating return water buffer tank, and the liquid outlet end of the condenser is used to recover the condensing medium.

[0018] It should be noted that the present invention does not specifically limit the specific model and structure of the condenser, and those skilled in the art can make adaptive adjustments according to actual conditions; wherein, the condenser can be a direct current condenser or a serpentine condenser, and the liquid at the liquid outlet of the condenser can be circulated to the hot water treatment device for further heating and recovery, and the condensing medium can be water.

[0019] As a preferred technical solution of the present invention, the temperature of the condensing medium in the condenser is 30°C to 35°C, for example, it can be 30°C, 30.5°C, 31°C, 31.5°C, 32°C, 32.5°C, 33°C, 33.5°C, 34°C, 34.5°C, 35°C, etc., but is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable.

[0020] It should be noted that the temperature of the condensing medium in the condenser tube in the present invention is 35°C to 40°C because the condensing medium after distillation can continue to be used and the condensing effect of the heat recovery device is the best; if the temperature is too high, the condensation effect will deteriorate and water and heat resources cannot be effectively recovered; if the temperature is too low, it will cause excessive material stress and affect the life of the machine.

[0021] As a preferred technical solution of the present invention, a cavity is provided on the outer surface of the condenser, a steam inlet is provided at one end of the cavity, and an air outlet and a liquid outlet are provided at the other end, the steam inlet is used for connecting the vacuum extraction device through a pipeline; the air outlet is used for connecting the exhaust steam treatment device, and the liquid outlet is used for discharging condensed waste water.

[0022] As a preferred technical solution of the present invention, the liquid outlet temperature of the liquid outlet of the cavity is 85°C to 95°C, for example, it can be 85°C, 86°C, 87°C, 88°C, 89°C, 90°C, 91°C, 92°C, 93°C, 94°C, 95°C, etc., but is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable.

[0023] As a preferred technical solution of the present invention, the circulating water return buffer tank pipeline is connected to a circulating water device.

The circulating water device can automatically input hot water or cold water into the circulating return water buffer tank according to the liquid temperature in the circulating return water buffer tank, adjust the liquid temperature in the circulating return water buffer tank, and keep its liquid temperature stable.

[0025] As a preferred technical solution of the present invention, the exhaust steam treatment device includes a washing tower and a circulating pump connected to the gas outlet of the washing tower by a pipeline. The washing tower is used to flush and purify the non-condensable gas treated by the heat recovery device, and the circulating pump is used to circulate and extract the non-condensable gas in the washing tower.

[0026] It should be noted that the exhaust steam in the present invention is directly discharged into the atmosphere, which will not only cause heat waste, but also may have a certain impact on the environment. The exhaust steam treatment device treats the exhaust steam, and leaves the recycled water resources through washing to reduce the emission of pollutants therein, such as removing the odor and harmful substances in the water vapor, reducing the pollution to the environment, and ensuring that the exhaust gas meets the national standards. Among them, the exhaust steam refers to the used steam discharged from the steamer and other equipment, and the non-condensable gas refers to the non-condensable gas generated after condensation and flushing of the exhaust steam treatment device.

[0027] Exemplarily, the workflow of the system device for brewing raw materials of the present invention includes:

[0028] After the brewing raw materials are steamed, the vacuum extraction device is started to extract the hot steam in the steamer to reduce the temperature of the brewing raw materials in the steamer; the heat recovery device collects the heat of the extracted steam and initially recovers and reuses water resources; the circulating return water buffer tank further recovers water resources, and the exhaust steam treatment device treats and absorbs the exhaust gas and recovers and reuses water resources.
