Description

Technical Field

[0001] The present application relates to the technical field of light-fragrance liquor preparation, and more specifically, to a liquor preparation device and a preparation process thereof based on light-fragrance liquor production. Background Art

[0002] Light-fragrance liquor occupies an important position in the liquor market with its unique brewing technology and flavor characteristics. The brewing technology of light-fragrance liquor includes raw material processing, koji making, mixed fermentation, distillation and blending.

[0003] The ceramic ground jar is a traditional fermentation container used for the mixed fermentation of light-fragrance liquor. It is usually buried underground with the mouth of the jar flush with the ground or slightly lower than the ground. This burial method creates a close heat exchange interface between the ground jar and the soil.

[0004] The traditional ground tank has limited insulation effect. In winter, the soil temperature is low. When the temperature of the mash in the ground tank rises, due to the low temperature of the soil, some of the heat will be transferred to the soil through the wall of the ground tank, thereby slowing down the rate of increase in the temperature of the mash. In summer, the soil temperature is high. At this time, if the temperature of the mash in the ground tank rises too quickly, the high temperature of the soil may aggravate this trend, making it easier for the temperature of the mash to exceed the suitable growth range of microorganisms. This makes it easy for the internal temperature of the ground tank to change due to changes in soil temperature when preparing light-fragrance liquor in traditional ground tanks, thereby affecting the fermentation effect of the wine.

[0005] In view of this, we propose a liquor preparation device and a preparation process based on the production of light-fragrance liquor. Summary of the invention

[0008] As an optional solution of the technical solution of this application document, the passive piston is located between the first thermal expansion and contraction layer and the first spring; One end of the heat-conducting tube seat away from the heat-conducting unit is connected to the outer heat-conducting air-permeable layer.

[0009] As an optional solution of the technical solution of the present application document, the heat introduction unit includes a heat-insulating substrate and a heat-insulating bottom support seat, and an elastic safety sac is connected between the heat-insulating substrate and the heat-insulating bottom support seat; A silicone thermal pad is connected to the other side of the thermal insulation base; A synchronous connecting rod is connected to the other side of the heat-insulating substrate, and an airflow reciprocating channel connected between the elastic insurance bag body and the inner cavity of the heat-conducting tube seat is arranged inside the synchronous connecting rod.

[0010] As an optional solution to the technical solution of the present application document, one end of the synchronous connecting rod away from the heat insulation substrate is sealed and penetrates the end of the heat-conducting tube seat, extends into the inner cavity of the heat-conducting tube seat, and is connected to the passive piston.

[0011] As an optional solution of the technical solution of this application document, the silicone thermally conductive gasket is arranged opposite to the inner thermally conductive breathable layer.

[0012] As an optional solution of the technical solution of this application document, the first thermosensitive expansion and contraction layer is located between the passive piston and the outer heat-conducting and breathable layer.

[0013] As an optional solution of the technical solution of this application document, the inner heat-conducting and breathable layer is sleeved and fixed on the outer periphery of the ground cylinder body; The heat output end of the electric heating belt is connected to the inner heat-conducting and breathable layer.

[0015] As an optional solution of the technical solution of the present application document, the cylinder head assembly includes a cylinder head body, and a non-contact temperature sensor is connected to the top wall of the inner cavity of the cylinder head body.

[0016] The technical solution of the present application provides a preparation process of a liquor preparation device based on the production of light-flavor liquor, comprising the following steps: S1. After placing the raw materials for brewing wine into the ground cylinder assembly, the cylinder cover assembly is closed on the end opening of the ground cylinder assembly; S2, burying the cylinder head assembly with the cover in the ground; S3. During the gradual fermentation of the raw materials inside the ground cylinder assembly, the soil temperature is sensed and monitored in real time through the heat-sensing tentacle structure between the outer heat-conducting and breathable layer and the inner heat-conducting and breathable layer in the heat source valve; S4. When the soil temperature is within the first preset temperature range, the geothermal heat energy triggers the heat-sensing tentacle structure to change from a contracted state to an extended state and contact the inner heat-conducting air-permeable layer, so that the geothermal heat can be continuously conducted to the ground cylinder body through the heat source valve, thereby maintaining the temperature of the mash in the ground cylinder assembly stable; S5. When the soil temperature is low, the heat-sensing tentacle structure is always in the initial contraction state and disconnected from the inner heat-conducting and breathable layer, cutting off the heat conduction between the cold source and the ground cylinder body in the ground cylinder assembly. When the soil temperature is higher than the first preset temperature range and within the second preset temperature range, the heat-sensing tentacle structure in the heat source valve member changes from the elongated state to the semi-contracted state, thereby cutting off the heat conduction between the soil and the ground cylinder body in the ground cylinder assembly again. S6. After the fermentation of the raw materials is completed, the lees are taken out from the inside of the ground tank assembly.

[0017] Beneficial effects: One or more technical solutions provided in the technical solution of the present application have at least the following technical effects or advantages: 1. When preparing light-fragrance liquor through the present device, the ground cylinder assembly buried underground can monitor and sense the soil temperature in real time. When the soil temperature is low in winter, the heat-sensing tentacle structure in the heat source valve component in the ground cylinder assembly is in a contracted state, cutting off the heat conduction between the cold source and the ground cylinder body in the ground cylinder assembly. When the soil temperature is high in summer, the heat-sensing tentacle structure in the heat source valve component will change from an extended state to a semi-contracted state, and then cut off the heat conduction between the soil and the ground cylinder body in the ground cylinder assembly again, thereby ensuring the thermal insulation effect of the present device in extreme environments, and then ensuring the fermentation effect during the preparation of light-fragrance liquor.

[0018] 2. The ceramic ground cylinder body has good air permeability. The central breathable insulation layer, the inner heat-conducting air-permeable layer and the outer heat-conducting air-permeable layer made of air-permeable materials in the heat source valve can ensure the thermal insulation effect of the ground cylinder body while enabling the microorganisms in the ground cylinder assembly to carry out necessary gas exchange with the external environment during the fermentation process, thereby creating a microenvironment suitable for the growth and fermentation of microorganisms. This air permeability helps the light-fragrance liquor to further form a unique aroma and taste during the fermentation process.

[0019] 3. During the gradual fermentation of the raw materials inside the ground cylinder assembly, the soil temperature is sensed and monitored in real time through the thermal tentacle structure between the outer heat-conducting and breathable layer and the inner heat-conducting and breathable layer in the heat source valve. When the soil temperature is within the first preset temperature range (that is, the phase change temperature range (20°C-35°C) of the first thermosensitive expansion layer (106)), the first thermosensitive expansion layer that expands due to heat drives the heat-conducting unit to contact the inner heat-conducting and breathable layer, thereby causing the geothermal heat energy to trigger the thermal tentacle structure to change from a contracted state to an extended state, allowing the geothermal heat to be continuously conducted to the ground cylinder body through the heat source valve, thereby maintaining the temperature of the mash in the ground cylinder assembly stable.

[0020] 4. Since the silicone thermally conductive gasket in the heat transfer unit is soft and elastic, this softness allows the silicone thermally conductive gasket to fit tightly on the curved surface of the inner heat-conductive breathable layer when the first thermally sensitive expansion layer expands due to heat and drives the silicone thermally conductive gasket in the heat transfer unit to contact the inner heat-conductive breathable layer, forming an effective heat conduction path, ensuring that the soil heat can be evenly and efficiently transferred to the main body of the ground cylinder.

[0021] 5. When the first thermosensitive expansion and contraction layer expands due to heat and drives the heat-conducting unit to move toward the inner heat-conducting breathable layer, the passive piston continuously squeezes the gas in the inner cavity of the heat-conducting tube seat into the elastic insurance sac through the airflow reciprocating channel. The expanded elastic insurance sac can press the aged and deformed silicone thermal gasket tightly against the surface of the inner heat-conducting breathable layer, so as to avoid the silicone thermal gasket being repeatedly squeezed and aged during the repeated expansion and contraction of the thermal tentacle structure, making it difficult to restore its shape, thereby reducing the fit between the thermal tentacle structure and the inner heat-conducting breathable layer, affecting the thermal conductivity of the heat source valve, and improving the thermal conduction stability of the thermal tentacle structure.

[0022] 6. When the soil temperature in summer is higher than the first preset temperature range (that is, the phase change temperature range of the first thermosensitive expansion layer (20℃-35℃)) and is within the second preset temperature range (that is, the phase change temperature range of the second thermosensitive expansion layer (35℃-50℃)), the first thermosensitive expansion layer is melted by heat, and the second thermosensitive expansion layer is gradually expanded by heat and drives the passive piston against the end of the counter-acting push rod to move in the opposite direction. The passive piston in the opposite direction presses the melted first thermosensitive expansion layer to cause the elastic pressure relief plate to undergo elastic deformation, and also continuously draws the gas inside the elastic insurance sac back into the inner cavity of the heat-conducting cylinder seat through the air flow reciprocating channel, so that the silicone thermally conductive gasket that moves synchronously with the passive piston loses contact with the inner heat-conducting breathable layer, so that the thermal tentacle structure that changes from an extended state to a semi-contracted state cuts off the heat conduction between the ground cylinder body and the soil in the ground cylinder assembly, thereby ensuring the thermal insulation effect of the ground cylinder assembly and preventing the high temperature of the soil in summer from affecting the temperature of the mash in the ground cylinder assembly.

The heat source valve member includes a central air-permeable heat-insulating layer 102. The central air-permeable heat-insulating layer 102 preferably has a microporous structure and is made of an aerogel material with certain air permeability.

The ceramic ground cylinder body 101 has good air permeability. The central breathable insulation layer 102, the inner heat-conducting breathable layer 104 and the outer heat-conducting breathable layer 103 made of breathable materials in the heat source valve can ensure the heat preservation and heat insulation effect of the ground cylinder body 101, and can also enable the microorganisms in the ground cylinder assembly 10 to exchange necessary gases with the external environment during the fermentation process, thereby creating a microenvironment suitable for the growth and fermentation of microorganisms. This air permeability helps the light-fragrance liquor to further form a unique aroma and taste during the fermentation process; The inner heat-conducting and breathable layer 104 is sleeved and fixed on the outer periphery of the ground cylinder body 101; A plurality of reserved openings are evenly provided on the central air-permeable heat-insulating layer 102, each of which is provided with a heat-sensing tentacle structure. A plurality of electric heating belts 117 are evenly connected to the central air-permeable heat-insulating layer 102, and the heat output end of the electric heating belt 117 is connected to the inner heat-conducting air-permeable layer 104; The thermal tentacle structure includes a heat-conducting tube seat 105, a heat-conducting unit is provided at the end of the heat-conducting tube seat 105, and an end of the heat-conducting tube seat 105 away from the heat-conducting unit is connected to the outer heat-conducting air-permeable layer 103; The inner cavity of the heat-conducting tube seat 105 is filled with a first heat-sensitive expansion and contraction layer 106, and the first heat-sensitive expansion and contraction layer 106 is composed of a temperature-sensitive paraffin material with a phase change temperature of 20°C-35°C; An inlet and an outlet are provided at the position corresponding to the position of the first thermal expansion and contraction layer 106 on the side wall of the thermal-conducting cartridge seat 105, and an elastic pressure relief sheet 118 is connected inside the inlet and an outlet is provided. A passive piston 111 is sealed and slidably provided in the inner cavity of the thermal-conducting cartridge seat 105, and a first spring connected between the passive piston 111 and the inner cavity end of the thermal-conducting cartridge seat 105 is also provided in the inner cavity of the thermal-conducting cartridge seat 105, the passive piston 111 is located between the first thermal expansion and contraction layer 106 and the first spring, and the first thermal expansion and contraction layer 106 is located between the passive piston 111 and the outer heat-conducting breathable layer 103; A straight groove is provided at the inner end of the heat-conducting tube seat 105, and a second heat-sensitive expansion and contraction layer 112 is filled in the straight groove.

A counter-acting push rod 113 is also sealed and slidably disposed in the straight groove, and an elastic reset member is disposed at the end of the counter-acting push rod 113; The elastic reset member includes a second spring 116 and a synchronous outer ring 115 sleeved on the outer periphery of the end of the counter-acting push rod 113; The second spring 116 is connected between the synchronous outer ring 115 and the inner end of the heat-conducting tube seat 105 .

[0036] When the device is used to prepare light-fragrance liquor, the ground cylinder assembly 10 buried underground can monitor and sense the soil temperature in real time. When the soil temperature is low in winter, the heat-sensing tentacle structure in the heat source valve component in the ground cylinder assembly 10 is in a contracted state, cutting off the heat conduction between the cold source and the ground cylinder body 101 in the ground cylinder assembly 10. When the soil temperature is high in summer, the heat-sensing tentacle structure in the heat source valve component will change from an extended state to a semi-contracted state, and then cut off the heat conduction between the soil and the ground cylinder body 101 in the ground cylinder assembly 10 again, thereby ensuring the thermal insulation effect of the device in extreme environments, and then ensuring the fermentation effect during the preparation of light-fragrance liquor.

[0037] During the gradual fermentation of the raw materials inside the ground cylinder assembly 10, the soil temperature is sensed and monitored in real time through the thermal tentacle structure between the outer heat-conducting and breathable layer 103 and the inner heat-conducting and breathable layer 104 in the heat source valve component. When the soil temperature is within the first preset temperature range (that is, the phase change temperature range (20°C-35°C) of the first thermosensitive expansion layer 106), the first thermosensitive expansion layer 106 that expands due to heat drives the heat-conducting unit to contact the inner heat-conducting and breathable layer 104, thereby causing the geothermal heat energy to trigger the thermal tentacle structure to change from a contracted state to an extended state, allowing the geothermal heat to be continuously conducted to the ground cylinder body 101 through the heat source valve component, thereby maintaining the temperature of the mash in the ground cylinder assembly 10 stable.

[0038] Reference Figures 4 to 6 , the embodiment of the present application provides a liquor preparation device based on the production of light-flavor liquor, the heat introduction unit includes a heat-insulating substrate 110 and a heat-insulating bottom support seat 108, and the heat-insulating substrate 110 and the heat-insulating bottom support seat 108 are both made of heat-insulating materials; An elastic safety bag 109 is connected between the heat-insulating substrate 110 and the heat-insulating bottom bracket 108; A silicone thermally conductive gasket 107 is connected to the other side of the thermally insulating base 108 , and the silicone thermally conductive gasket 107 is arranged opposite to the inner thermally conductive and breathable layer 104 ; A synchronous connecting rod 114 is connected to the other side of the insulation substrate 110. The interior of the synchronous connecting rod 114 is provided with a round-trip air flow channel connecting the elastic safety bag 109 and the inner cavity of the thermal tube seat 105. The end of the synchronous connecting rod 114 away from the insulation substrate 110 is sealed and passes through the end of the thermal tube seat 105, extends into the inner cavity of the thermal tube seat 105, and is connected to the passive piston 111.

[0039] Since the silicone thermally conductive gasket 107 in the heat transfer unit is soft and elastic, this softness allows the silicone thermally conductive gasket 107 to fit tightly onto the curved surface of the inner heat-conductive breathable layer 104 when the first thermosensitive expansion and contraction layer 106 expands due to heat and drives the silicone thermally conductive gasket 107 in the heat transfer unit to contact the inner heat-conductive breathable layer 104, thereby forming an effective heat conduction path, thereby ensuring that the soil heat can be evenly and efficiently transferred to the ground cylinder body 101.

[0040] When the first thermosensitive expansion and contraction layer 106 expands due to heat and drives the heat-conducting unit to move toward the inner heat-conducting breathable layer 104, the passive piston 111 continuously squeezes the gas in the inner cavity of the heat-conducting tube seat 105 into the elastic safety sac 109 through the airflow reciprocating channel. The expanded elastic safety sac 109 can press the aged and deformed silicone thermal gasket 107 tightly against the surface of the inner heat-conducting breathable layer 104, so as to prevent the silicone thermal gasket 107 from being repeatedly squeezed and aged during the repeated expansion and contraction of the thermal tentacle structure, making it difficult to restore its shape, thereby reducing the fit between the thermal tentacle structure and the inner heat-conducting breathable layer 104, thereby affecting the thermal conductivity of the heat source valve.

[0041] When the soil temperature in summer is higher than the first preset temperature range (that is, the phase change temperature range of the first thermosensitive expansion and contraction layer 106 (20°C-35°C)) and is within the second preset temperature range (that is, the phase change temperature range of the second thermosensitive expansion and contraction layer 112 (35°C-50°C)), the first thermosensitive expansion and contraction layer 106 is melted by heat, and the second thermosensitive expansion and contraction layer 112 is gradually expanded by heat and drives the passive piston 111 against the end of the counter-acting push rod 113 to move in the reverse direction. The passive piston 111 moving in the reverse direction presses the melted first thermosensitive expansion and contraction layer 106 to make the elastic pressure relief sheet During the elastic deformation of 118, the gas inside the elastic safety bag 109 is continuously drawn back into the inner cavity of the heat-conducting tube seat 105 through the reciprocating air flow channel, so that the silicone thermal gasket 107 that moves synchronously with the passive piston 111 loses contact with the inner heat-conducting breathable layer 104, and the heat-sensing tentacle structure that changes from an extended state to a semi-contracted state cuts off the heat conduction between the ground cylinder body 101 in the ground cylinder assembly 10 and the soil, thereby ensuring the thermal insulation effect of the ground cylinder assembly 10 and preventing the high temperature of the soil in summer from affecting the temperature of the mash in the ground cylinder assembly 10.

[0042] Reference Figure 1 and Figure 2 The embodiment of the present application provides a liquor preparation device based on light-fragrance liquor. The cylinder head assembly 20 includes a cylinder head body 201. A non-contact temperature sensor 202 is connected to the top wall of the inner cavity of the cylinder head body 201. The non-contact temperature sensor 202 is preferably an infrared temperature sensor.

[0043] The temperature of the raw materials being fermented in the ground cylinder assembly 10 is monitored in real time by the non-contact temperature sensor 202 in the cylinder cover assembly 20. The non-contact temperature sensor 202 transmits the detection result to the external main controller in real time. When it is cold in winter and the soil temperature is low, causing the temperature detected by the non-contact temperature sensor 202 to be lower than the first preset temperature range, the external main controller controls the electric heating belt 117 to turn on and heat the ground cylinder body 101 to a preset 30°C.

[0044] The present application embodiment provides a preparation process of a liquor preparation device based on the production of light-flavor liquor, comprising the following steps: S1, after the raw materials for brewing are placed in the ground cylinder assembly 10, the cylinder cover assembly 20 is covered on the end opening of the ground cylinder assembly 10; S2, after the covered cylinder head assembly 20 is buried underground, the temperature of the raw materials being fermented in the ground cylinder assembly 10 is monitored in real time by the non-contact temperature sensor 202 in the cylinder head assembly 20; S3, during the gradual fermentation of the raw materials inside the ground cylinder assembly 10, the soil temperature is sensed and monitored in real time through the heat-sensing tentacle structure between the outer heat-conducting and air-permeable layer 103 and the inner heat-conducting and air-permeable layer 104 in the heat source valve component; S4. When the soil temperature is within the first preset temperature range, the geothermal heat energy triggers the heat-sensing tentacle structure to change from a contracted state to an extended state and contact the inner heat-conducting air-permeable layer 104, so that the geothermal heat can be continuously conducted to the ground cylinder body 101 through the heat source valve, thereby maintaining the temperature of the fermented grains in the ground cylinder assembly 10 stable; S5. When the soil temperature is low, the heat-sensing tentacle structure is always in the initial contraction state and disconnected from the inner heat-conducting and breathable layer 104, cutting off the heat conduction between the cold source and the ground cylinder body 101 in the ground cylinder assembly 10. When the soil temperature is higher than the first preset temperature range and within the second preset temperature range, the heat-sensing tentacle structure in the heat source valve member changes from the elongated state to the semi-contracted state, thereby cutting off the heat conduction between the soil and the ground cylinder body 101 in the ground cylinder assembly 10 again. S6. After the fermentation of the raw materials is completed, the lees are taken out from the inside of the ground cylinder assembly 10.

10. A preparation process of a liquor preparation device based on the production of light-flavor liquor according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1, after placing raw materials for brewing wine into the interior of the ground cylinder assembly (10), the cylinder cover assembly (20) is closed on the end opening of the ground cylinder assembly (10); S2, burying the cylinder head assembly (20) covered underground; S3, during the gradual fermentation of the raw materials inside the ground cylinder assembly (10), the soil temperature is sensed and monitored in real time through the heat-sensing tentacle structure between the outer heat-conducting and breathable layer (103) and the inner heat-conducting and breathable layer (104) in the heat source valve component; S4. When the soil temperature is within a first preset temperature range, the geothermal heat energy triggers the heat-sensing tentacle structure to change from a contracted state to an extended state and contact the inner heat-conducting and breathable layer (104), so that the geothermal heat can be continuously conducted to the ground cylinder body (101) through the heat source valve component, thereby maintaining the temperature of the mash in the ground cylinder assembly (10) stable; S5.
