Description

Technical Field

[0001] The present application relates to a solid-state distillation device, and more particularly to a hot-cold dual-air switching solid-state distillation device that dries an object by hot air or cools an object by cold air. Background Art

[0002] Solid-state fermentation of pure grains is a common traditional brewing process. For example, the brewing process of sorghum wine is roughly divided into three parts: koji making, brewing and packaging. The brewing process includes soaking, steaming, cooling, mixing koji, fermentation, distillation, cooling, re-mixing koji, re-fermentation and re-distillation.

[0003] The aforementioned distillation is a separation method that utilizes thermodynamics, utilizing the difference in boiling points of the components in a liquid or solid-liquid mixture to allow the low-boiling-point components to evaporate first and then condense. For example, a simple distillation method is commonly used to produce distilled liquor by collecting evaporated alcohol and condensing it. The conventional solid-state fermentation distillation method is to cool the fermented mash after solid-state fermentation distillation, and then perform solid-state fermentation and distillation for different times according to the conditions and requirements of fermentation distillation. Utility Model Content

[0004] Since the fermented mash undergoes multiple solid-state fermentation and distillation, when the water content of the fermented mash is too high, it will directly affect the operation and effect of the next round of distillation. Although it is generally handled by adding auxiliary materials, in the case where no auxiliary materials are used or no auxiliary materials can be added, the only way to reduce the amount collected during distillation is to reduce the water content of the fermented mash used in the next round, which ultimately leads to poor fermentation results in the next round. At the same time, if the water content of the distilled mash is high, it will cause poor operation and poor physical state when it is poured out and cooled, which will destroy the subsequent fermentation and distillation process.

[0005] In view of the above-mentioned deficiencies in the prior art, the applicant of this case believes that it is necessary to conceive a device that can effectively reduce the water content of the fermented mash and prevent damage to subsequent fermentation and distillation, thereby improving the effect of solid-state fermentation and distillation, so as to obtain an ideal collection quantity and quality.

[0006] In order to achieve the above-mentioned purpose, the present application provides a hot and cold dual-wind switching solid-state distillation equipment, including a distillation pot, a heating device, a condensing device, and an airflow conveying unit. The distillation pot includes a distillation pot body, a pot cover body covering the top side of the distillation pot body, and the pot cover body has an opening connected to the inside of the distillation pot body. The heating device is connected to the distillation pot body. The condensing device is connected to the rear end of the opening. The airflow conveying unit is connected to the distillation pot body and conveys hot air to the inside of the distillation pot body to air-dry the objects inside the distillation pot body, or conveys cold air to the inside of the distillation pot body to cool the objects.

[0007] Furthermore, the airflow conveying unit includes an airflow control valve arranged on the bottom side of the distillation pot body, a fan connected to the airflow control valve, a heater and a cooler connected to the fan, and a master controller connected to and controlling the fan, the heater and the cooler. The fan drives the airflow outside the distillation pot body to flow into the distillation pot body and is heated by the heater to generate the hot air, or cooled by the cooler to generate the cold air.

[0008] Furthermore, the airflow conveying unit includes an airflow control valve arranged on the bottom side of the distillation pot body, a first fan connected to the airflow control valve and connected to a heater, a second fan connected to the airflow control valve and connected to a cooler, and a master controller connected to and controlling the first fan, the heater, the second fan and the cooler. The first fan drives the airflow outside the distillation pot body to flow into the distillation pot body and is heated by the heater to generate the hot air, or the second fan drives the airflow outside the distillation pot body to flow into the distillation pot body and is cooled by the cooler to generate the cold air.

[0009] Furthermore, the heating device is a steam spraying device for spraying steam toward the interior of the distillation pot body.

[0010] Furthermore, the steam spraying device includes a pipeline arranged on the bottom side of the distillation pot body and having a nozzle, a steam generator connected to the pipeline and arranged on the outside of the distillation pot body, and a switch for operating the steam generator on and off.

[0011] Furthermore, a connecting pipe connected to the condensing device is arranged on the opening of the pot cover body, and the connecting pipe includes a swan neck arranged on the opening, and a Lynn arm arranged at one end of the swan neck and extending toward one side with a gradually decreasing height.

[0012] Furthermore, the condensing device includes a cooling pipe connected to the rear end of the Lynn arm, a condensing tube arranged in the cooling pipe and connected to the interior of the distillation pot body, and a cooling medium device connected to the cooling pipe. A cooling medium flow space is formed between the cooling pipe and the condensing tube for the cooling medium device to transport low-temperature medium for condensation and liquid extraction.

[0013] Furthermore, a pressure relief valve is arranged on the pot cover body.

[0014] Furthermore, a drainage valve offset from the airflow conveying unit is provided on the bottom side of the distillation pot body.

[0015] Furthermore, a retort plate fixing member for mounting a retort plate is arranged inside the main body of the distillation pot, and the retort plate is provided with a plurality of ventilation holes.

[0016] The present application sets an air flow conveying unit on the bottom side of the distillation pot. On the one hand, it can convey hot air into the distillation pot to prompt the objects in the distillation pot to discharge water to reduce their water content. On the other hand, it can cool down the objects by conveying cold air to reduce their temperature. The air-dried or cooled objects can be used for subsequent solid-state fermentation and distillation, ultimately obtaining the ideal amount and quality. BRIEF DESCRIPTION OF THE DRAWINGS
