Description

Novel coffee bean fermentation device

Technical Field

The utility model relates to a novel coffee bean fermentation device belongs to coffee bean processing equipment field.

Background

The outer surface of the fresh coffee beans is wrapped with the outer skin, the inner skin and the pulp, and the coffee beans in the fresh coffee beans can be obtained only by peeling, fermenting and cleaning after being picked. The purpose of the coffee bean fermentation is to separate the greasy mucilage that covers the endocarp. The coffee bean fermentation process is to store the coffee beans in the fermentation device for about 12-36 hours, the time being determined mainly by the ambient temperature, the thickness of the mucilage and the enzymes. After the process is finished, the greasy mucilage on the endocarp around the coffee beans is separated from the endocarp and falls off, so that the coffee beans are not sticky and smooth any more and have pebble-like hand feeling, but the greasy mucilage is still contacted with the endocarp and needs to be cleaned, stirred and separated subsequently, the difficulty of subsequent operation is increased, and the efficiency is reduced. Equipment cleanliness control is critical to prevent coffee beans from rotting throughout the fermentation process, as even if only one coffee bean is rotten, it may damage all of the coffee beans. The taste and quality of the coffee can be improved under a suitable fermentation environment, and the high-quality product rate of the coffee is determined by the cleaning efficiency and cleanness.

At present, coffee bean fermentation equipment consists of a simple fermentation tank, the fermentation tank is difficult to clean and remove impurities, the fermentation temperature is influenced by the environment and the weather, the temperature of the middle part in the fermentation tank is higher than the peripheral temperature, so that the fermentation is not uniform, the coffee bean fermentation is unstable, the fermentation time is not easy to determine, the phenomena of over-fermentation and under-fermentation often occur, and the coffee bean quality is seriously influenced. The fermentation liquor is inconvenient to supply, and the fermented fermentation liquor and the coffee beans are difficult to separate after fermentation. And the fermentation liquor in the fermentation tank and the coffee beans are difficult to be fully mixed, so that the fermentation efficiency is greatly reduced, and the fermentation time is prolonged. The existing fermentation mode is easy to breed bacteria due to the untight disinfection environment, so that the taste and the component retention of the coffee beans are influenced; the fermentation at normal temperature is easy to ferment and deteriorate due to the uncontrollable environment temperature change; the existing fermentation aims to remove outer pectin, the quality of coffee is improved by neglecting microbial beneficial bacteria generated in the fermentation process, and valuable components are lost.
