Coffee high-temperature processing pre-fermentation device

Abstract

The invention discloses a coffee high-temperature processing pre-fermentation device. The coffee high-temperature processing pre-fermentation device is characterized by comprising an outer barrel wall, a discharging port, a control part, a feeding port sealing door, a water inlet, an exhaust fan, an exhaust pipe, a support, an inner barrel wall, a motor, a stirring rod, a spraying head, a microprocessor chip, a microcomputer timer, a storage, a PH measuring instrument, a temperature sensor, a humidity sensor and a carbon dioxide measuring instrument. The device can automatically monitor and adjust the temperature and humidity and can also monitor the PH value of coffee beans in the fermentation process in real time so that the fermentation process and quality can be controlled in real time; due to the fact that carbon dioxide can be generated in the coffee fermentation process, fermentation can be affected by excessive carbon dioxide, and explosion hidden danger can be caused when a large amount of carbon dioxide is gathered in a tank, a carbon dioxide concentration detection device is designed for the device; and when the carbon dioxide is excessive, the carbon dioxide can be discharged.

Description

technical field [0001] The invention belongs to the technical field of coffee fermentation, and in particular relates to a coffee high-temperature processing pre-fermentation device. Background technique [0002] The excellent geography and climatic environment of Yunnan are suitable for the growth of arabica coffee, and have formed the unique flavor of Yunnan arabica coffee "thick but not bitter, fragrant but not strong, slightly fruity", which is very popular in the international coffee market; After harvesting, the primary processing should be started immediately; in my country, the primary processing of coffee includes natural fermentation method, mechanical method, and solarization method (drying method). In places where water is scarce, mechanical method is used; Primary processing equipment and technology, but these equipment and technology can not be well integrated with arabica coffee grown in Yunnan Province; fermentation is a complex biochemical reaction; coffee bea...

AI Technical Summary

Problems solved by technology

[0004] The currently used coffee pre-fermentation device is not suitable for the wet fermentation of Yunnan arabica coffee. The main problems are: 1. The temperature and humidity cannot be automatically adjusted; 2. The pH value of the coffee beans in the fermentation tank cannot be monitored in real time during the fermentation process. , to control the fermentation quality in real time; 3. It is impossible to discharge carbon dioxide during the fermentation process; 4. It is impossible to stir the coffee beans at regular intervals to make them ferment evenly
