Description

Technical Field

[0001] The utility model relates to the technical field of coffee fermentation, in particular to a coffee bean fermentation storage device. Background Art

[0002] In my country, the primary processing of coffee includes natural fermentation, mechanical method, and sun drying (drying method). In water-scarce areas, mechanical method is used. Some companies have introduced primary processing equipment and technology from Brazil, Colombia and other countries, but these equipment and technology cannot be well integrated with the small-grain coffee grown in Yunnan Province. Fermentation is a complex biochemical reaction. The improvement in the quality of coffee beans through wet fermentation is closely related to material transformation. The synthesis and transformation of organic acids are the most important components of material metabolism. Studies have found that there are 6 main organic acids that affect the sourness of coffee fermentation, namely malic acid, citric acid, lactic acid, acetic acid, succinic acid and oxalic acid. The production of propionic acid and butyric acid is a manifestation of excessive fermentation, which will reduce the quality of coffee and make the coffee too sour and bitter.

[0003] After searching, it was found that the application number is CN202011134826.9, and the name is a high-temperature processing pre-fermentation device for coffee. The application pointed out that the currently used coffee pre-fermentation device cannot automatically adjust the temperature and humidity, cannot monitor the pH value of the coffee beans in the fermentation tank in real time during the fermentation process, cannot control the fermentation quality in real time, cannot discharge the carbon dioxide in the fermentation process, and cannot stir the coffee beans at regular intervals to make it ferment evenly. The humidity is adjusted by the spray head, the temperature is adjusted by ventilation, the carbon dioxide is discharged by ventilation, and the stirring is performed by the stirring rod to improve the uniformity of fermentation. However, during ventilation, the application allows miscellaneous bacteria in the outside air to enter the fermentation barrel, contaminating the fermentation bacteria and affecting the fermentation process. It is not safe and reliable enough, and further improvements can be made.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0029] According to an embodiment of the present invention, a coffee bean fermentation storage device is provided.

[0030] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. Figure 1-4As shown, a coffee bean fermentation and storage device according to an embodiment of the present invention includes a fermentation tank 1 and a driving motor 2. A spiral tube 3 is fixedly installed on the inner wall of the fermentation tank 1. The spiral tube 3 is a copper tube, and the two ends of the spiral tube 3 are respectively connected with an inlet pipe 4 and a drain pipe 5. The driving motor 2 is fixedly installed on the top surface of the fermentation tank 1, and a stirring paddle 6 is installed on the output end of the driving motor 2. The stirring paddle 6 passes through the top surface of the fermentation tank 1 and is rotatably connected to the top surface of the fermentation tank 1 through a sealed bearing to reduce air leakage. The stirring paddle 6 is located on the inner side of the spiral tube 3. The inlet pipe 4 and the drain pipe 5 are both connected to an industrial chiller, which is not shown in the figure. A negative ion air purifier 8 is fixedly installed on the surface of one side of the fermentation tank 1 through a cantilever 7. It is a common air sterilization and purification equipment and will not be described in detail here. The output end of the negative ion air purifier 8 is connected to the inside of the fermentation tank 1 through an air inlet pipe 9. A gas concentration detector 11 and a temperature and humidity changer are respectively installed on the top surface of the fermentation tank 1 on one side of the driving motor 2. The transmitter 12 and the pressure relief valve 13 are both common equipment in this field. The temperature and humidity transmitter 12 detects the temperature inside the fermentation tank 1. When the fermentation temperature is high, the industrial chiller starts and injects cold water into the spiral tube 3. The temperature of the coffee bean fermentation raw materials is reduced through the spiral tube 3, eliminating the problem of ventilation and heat dissipation that easily causes water loss, resulting in reduced humidity and invasion of external bacteria, thereby improving the safety of temperature control and the convenience of use. At the same time, the gas concentration detector 11 detects the carbon dioxide concentration inside the fermentation tank 1. When the concentration is too high, the negative ion air purifier 8 is started, and the outside air is discharged into the fermentation tank 1 after purification. The air sterilized and purified by the negative ion air purifier 8 dilutes the carbon dioxide concentration inside the fermentation tank 1 to avoid excessive concentration affecting the fermentation process. At the same time, the pressure relief valve 13 is used to relieve pressure to avoid excessive pressure inside the fermentation tank 1, facilitating ventilation while ensuring the safety of fermentation, thereby improving the safety of the overall fermentation work and improving the fermentation efficiency.

[0031] In one embodiment, a humidifier 14 is installed on one side of the fermentation tank 1, and the output end of the humidifier 14 is connected to the interior of the fermentation tank 1 through an air pipe 15. Sterile water is added to the inside of the humidifier 14. When the humidity inside the fermentation tank 1 is low, the humidifier 14 processes the sterile water into water mist, which is input into the interior of the fermentation tank 1 through the air pipe 15 to increase the humidity. The water mist can evenly and stably increase the humidity, and the work efficiency is higher. At the same time, sterile water also avoids the growth of miscellaneous bacteria, further improving the safety of fermentation.

[0032] In one embodiment, a controller 18 is fixedly installed on the front facade of the fermentation tank 1, and the output end of the controller 18 is electrically connected to the input end of the drive motor 2 and the input end of the negative ion air purifier 8. This is a common control structure in the art and will not be described in detail here.

[0033] In one embodiment, a discharge pipe 16 is connected to the bottom of the fermentation tank 1, and a gate valve 17 is installed on the surface of the discharge pipe 16 to facilitate discharge.

[0034] In one embodiment, the water inlet pipe 4 is connected to the water outlet of the industrial chiller, and the drain pipe 5 is connected to the water inlet of the industrial chiller. This is a common cooling structure and will not be described in detail here.

[0035] In one embodiment, the output end of the temperature and humidity transmitter 12 is electrically connected to the input end of the industrial chiller and the humidifier 14 respectively, so as to facilitate automatic control of temperature and humidity.

[0036] In one embodiment, a feed pipe 10 is connected to the top surface of the fermentation tank 1, and a sealing cover is spirally sleeved on the top of the feed pipe 10. The feed pipe 10 is convenient for loading coffee bean fermentation raw materials, and the sealing cover is used to close the feed pipe 10.

[0037] In one embodiment, the pressure relief valve 13 is connected to the fermentation tank 1, and the temperature and humidity transmitter 12 probe is inserted into the coffee bean fermentation raw material to facilitate the detection of temperature and humidity.

[0038] Working principle:

[0039] The spiral tube 3 is connected to the industrial chiller through the water inlet pipe 4 and the drain pipe 5, and the temperature and humidity transmitter 12 detects the temperature inside the fermentation tank 1. When the fermentation temperature is high, the industrial chiller starts and injects cold water into the spiral tube 3. The temperature of the coffee bean fermentation raw material is lowered through the spiral tube 3, eliminating the problem of ventilation and heat dissipation that easily causes water loss, resulting in reduced humidity and invasion of external bacteria, thereby improving the safety of temperature control and the convenience of use. At the same time, the gas concentration detector 11 detects the carbon dioxide concentration inside the fermentation tank 1. When the concentration is too high, the negative ion air purifier 8 is started, and the external air is discharged into the fermentation tank 1 after purification, and is sterilized by the negative ion air purifier 8. The purified air dilutes the carbon dioxide concentration inside the fermentation tank 1 to prevent excessive concentration from affecting the fermentation process. At the same time, the pressure relief valve 13 is used to relieve pressure to prevent the internal pressure of the fermentation tank 1 from being too high, which facilitates ventilation while ensuring the safety of fermentation, thereby improving the safety of the overall fermentation work and improving the fermentation efficiency. At the same time, sterile water is added to the humidifier 14. When the humidity inside the fermentation tank 1 is low, the humidifier 14 processes the sterile water into water mist and inputs it into the fermentation tank 1 through the air pipe 15 to increase the humidity. The water mist can evenly and stably increase the humidity, and the working efficiency is higher. At the same time, sterile water also prevents the growth of miscellaneous bacteria, further improving the safety of fermentation.
