Description

Technical Field

[0001] This utility model relates to the field of fruit wine fermentation technology, and specifically discloses a fruit wine fermentation cooling device. Background Technology

[0002] Papaya, also known as sour papaya, is a fruit rich in nutrients and with a unique flavor, often used to make fruit wine. Temperature control is one of the key factors in the fermentation process of papaya fruit wine. A suitable fermentation temperature ensures yeast activity, promotes a smooth fermentation process, and thus improves the quality and yield of the fruit wine.

[0003] Current fruit wine fermentation cooling devices using Duoyi fruit for making fruit wine mostly employ a single refrigeration mode (such as jacketed water cooling or external condenser) during fermentation and cooling, resulting in coarse temperature control. Due to the high sugar content and intense heat generation during fermentation of Duoyi fruit, traditional cooling methods are difficult to achieve precise temperature control, which can easily lead to over-fermentation or the growth of miscellaneous bacteria. Therefore, improvements are needed. Utility Model Content

[0004] This invention proposes a fruit wine fermentation cooling device. This device significantly improves cooling efficiency through dual high-efficiency cooling of water and cold air, and precise temperature control, effectively preventing the growth of miscellaneous bacteria and ensuring the quality of fruit wine fermentation.

The first baffle plate and the second baffle plate are fixedly installed at the top and bottom of the cooling box, respectively.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figure 1-4 A fruit wine fermentation cooling device includes a base plate 1, a fermentation tank 2 disposed above the base plate 1, a feed pipe 203 with a sealing cover disposed on the top of the fermentation tank 2, an exhaust pipe 204 with an exhaust valve disposed on the top of the fermentation tank 2, a cooling chamber 3 disposed between the inner and outer walls of the fermentation tank 2, a serpentine cooling pipe 4 disposed inside the cooling chamber 3, the two ends of the cooling pipe 4 passing through the cooling chamber 3 and extending to the outside of the fermentation tank 2, the cooling pipe 4 including a water cooling pipe 401, and a cold air pipe 402 that can be introduced into the water cooling pipe 401;

[0024] A cooling box 6 is provided on the outside of the fermenter 2 to provide cold air to the cold air pipe 402. The top of the cooling box 6 is connected to the air inlet pipe 601. A fan 603 is fixedly installed inside the air inlet pipe 601. A filter screen 602 is detachably connected to the air inlet port of the fan 603. The cooling box 6 is arranged in sequence according to the direction of gas flow, including a first cooler 7, a first baffle plate 701, a second cooler 8, and a second baffle plate 801. The first baffle plate 701 and the second baffle plate 801 are fixedly installed at the top and bottom of the cooling box 6, respectively. The heat dissipation ends of the first cooler 7 and the second cooler 8 penetrate the bottom and top of the cooling box 6 and extend to the outside of the cooling box 6, respectively.

[0025] In this embodiment: During the fermentation process, two temperature sensors 205 on the inner wall of the fermentation tank 2 monitor the internal temperature in real time and transmit the data to the PLC touch screen all-in-one machine on the outer wall of the fermentation tank 2. By preset a suitable fermentation temperature range on the PLC touch screen all-in-one machine, when the monitored temperature exceeds the range, the start-up and shutdown and power of the chiller 5, water pump 501, fan 603, first cooler 7 and second cooler 8 are automatically controlled to precisely adjust the cooling intensity. During the cooling process, the chiller 5 produces low-temperature water, and the water pump 501 pumps the cold water into the water-cooled pipe 401 of the cooling pipe 4 through the water inlet pipe 502. After the cold water absorbs the heat of the fermentation tank 2 in the pipe, it flows back to the chiller 5 through the return water pipe 503 to cool down again, and the heat is carried away in a cycle.

[0026] The blower 603 draws outside air into the cooling box 6 through the air inlet pipe 601. The air is filtered sequentially through the filter screen 602 and then passes through the first cooler 7, the first baffle plate 701, the second cooler 8, and the second baffle plate 801, where it is gradually cooled. The cooled air enters the cold air pipe 402 through the connecting pipe 802, further reducing the temperature of the fermentation tank 2. The cold air is finally discharged through the air outlet pipe 403. The dual cooling method combining water cooling and cold air significantly improves the cooling efficiency, ensuring that fermentation takes place at a suitable temperature and effectively preventing yeast inactivation or the growth of miscellaneous bacteria.

[0027] As a technical optimization of this utility model, the end of the cooling box 6 away from the air inlet pipe 601 is connected to a connecting pipe 802, the other end of the connecting pipe 802 is connected to one end of the cooling pipe 402, the other end of the cooling pipe 402 is connected to an air outlet pipe 403 extending to the outside of the water cooling pipe 401, and a one-way valve 404 is provided on the outer wall of the air outlet pipe 403.

[0028] In this embodiment: the cold air from the cooling box 6 can be delivered to the cold air pipe 402 through the connecting pipe 802 to cool the fermentation tank 2. After the cold air completes the cooling task, it is discharged through the air outlet pipe 403. The one-way valve 404 on the outer wall of the air outlet pipe 403 ensures that the cold air can only be discharged in one direction, preventing outside air or water in the water cooling pipe 401 from flowing back into the cold air pipe 402, thus ensuring the stable operation of the cold air circulation system.

[0029] As a technical optimization of this utility model, a chiller 5 is provided below the cooling box 6, and a water pump 501 is provided on the outside of the chiller 5. The input end of the water pump 501 is connected to the outlet of the chiller 5 through a pipe, and the output end of the water pump 501 is connected to one end of the water cooling pipe 401 through the water inlet pipe 502. The other end of the water cooling pipe 401 is connected to the inlet of the chiller 5 through the return water pipe 503.

[0030] In this embodiment: the chiller 5 (a compression refrigeration unit) serves as the core refrigeration equipment. It cools the water through its own refrigeration system to produce a low-temperature coolant, which provides a cold source for the entire water cooling cycle. The water pump 501 is started, and the low-temperature coolant prepared by the chiller 5 is extracted using its own power. Under the pressure drive of the water pump 501, the coolant is transported along the water inlet pipe 502 to the water cooling pipe 401 of the cooling pipe 4.

[0031] As a technical optimization of this utility model, two temperature sensors 205 distributed vertically are fixedly installed on the inner wall of the fermenter 2.

[0032] In this embodiment: Temperature sensor 205 (PT100 platinum resistance temperature sensor) monitors the temperature of the fermentation broth in real time and feeds it back to the PLC touch screen all-in-one machine.

[0033] As a technical optimization of this utility model, a motor 201 is fixedly installed on the top of the fermentation tank 2, and the output end of the motor 201 passes through the top of the fermentation tank 2 and is fixedly installed with a stirring rod 202.

[0034] In this embodiment: starting the motor 201 can drive the stirring rod 202 to rotate and stir the fermentation liquid, causing the fermentation liquid to flow in different directions and speeds, forming a complex fluid movement trajectory, which promotes full mixing between different parts of the fermentation liquid. On the one hand, the regions with different concentrations and components in the Duoyiguo fermentation liquid are evenly distributed, ensuring that the fermentation substrate and yeast are in full contact, thus improving fermentation efficiency. On the other hand, during the cooling process, stirring can accelerate the heat exchange between the fermentation liquid and the wall of the fermentation tank 2, making the temperature distribution of the fermentation liquid more uniform, avoiding local overheating or undercooling, and preventing uneven temperature from affecting yeast activity or causing the growth of miscellaneous bacteria.

[0035] As a technical optimization of this utility model, a PLC touch screen all-in-one machine is installed on the outer wall of the fermentation tank 2.

[0036] In this embodiment, the PLC touch screen all-in-one machine (Siemens SIMATICHMIKTP700Basic) is electrically connected to the motor 201, two temperature sensors 205, exhaust valve, first cooler 7 (gas cooler semiconductor refrigeration AC-046), second cooler 8 (American TE Technology gas cooler semiconductor refrigeration AC-046), fan 603, and water pump 501, which facilitates the control of the operation of each component.

[0037] As a technical optimization of this utility model, the fermenter 2 is fixedly installed on the top of the base plate 1 by the support frame 101.

[0038] In this embodiment: the support frame 101 facilitates the fixing of the position of the fermentation tank 2.

[0039] The working principle and usage process of this utility model are as follows: When in use, the sealing cover is opened and the raw material of Duoyiguo is added into the fermentation tank 2 through the feed pipe 203. During the fermentation process, the motor 201 drives the stirring rod 202 to stir the fermentation liquid, so that the temperature distribution is uniform and the heat transfer is accelerated. The exhaust valve on the exhaust pipe 204 discharges the gas generated during fermentation. At the same time, the two temperature sensors 205 on the inner wall of the fermentation tank 2 monitor the internal temperature in real time and transmit the data to the PLC touch screen all-in-one machine on the outer wall of the fermentation tank 2. By preset a suitable fermentation temperature range on the PLC touch screen all-in-one machine, when the monitored temperature exceeds the range, the PLC touch screen all-in-one machine starts the chiller 5 to produce low-temperature water. The water pump 501 pumps the cold water into the water cooling pipe 401 of the cooling pipe 4 through the water inlet pipe 502. After the cold water absorbs the heat of the fermentation tank 2 in the pipe, it flows back to the chiller 5 through the return water pipe 503 to cool down again and circulate away the heat.

[0040] Meanwhile, the fan 603 draws outside air into the cooling box 6 through the air inlet pipe 601. The air is filtered sequentially through the filter screen 602 and then passes through the first cooler 7, the first baffle plate 701, the second cooler 8, and the second baffle plate 801, where it is gradually cooled. The cooled air enters the cold air pipe 402 through the connecting pipe 802, further reducing the temperature of the fermentation tank 2. The cold air is finally discharged through the air outlet pipe 403. The one-way valve 404 can prevent backflow of external airflow. Thus, by adopting a dual cooling method that combines water cooling and cold air, the cooling efficiency is greatly improved, ensuring that fermentation takes place at a suitable temperature.
