Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing, and the structure and principle of this device are very clear to those skilled in the art. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0015] The present invention is a method of processing coffee fruit at low temperature, which must be carried out in a special / constant temperature and humidity space, and the constant temperature and humidity environment in the entire low temperature room can be simply passed through some existing commercial refrigerators and Humidity machine to meet the required setting standards, the low temperature treatment method shall not exceed 4 degrees Celsius, including freezing treatment. After the fruit is picked, it is sent to the low-temperature room on the same day, and the fruit is placed on a special display rack with breathable mate...

Abstract

The present invention relates to a coffee processing technical field and specifically to a raw coffee fruit low temperature and freezing processing method including a temperature and humidity constant space. The concrete steps are as follows: the raw coffee fruits are pickled, the pickled raw coffee fruits are sent into the temperature and humidity constant space, the raw coffee fruits are placed in display shelves, breathable materials are spread on the display shelves, and the temperature of the temperature and humidity constant space is maintained below 4 DEG C; Under low temperatures, the moisture of the raw fruits is evaporated, which requires 2 weeks to 2 months. Then the raw fruits are washed with water and the fruit pulps of the washed raw fruits are removed, the treated raw fruits are sun-dried for 7-14 days until the water content decreases to 15%. In freezing conditions, the moisture of the raw fruits is evaporated, which needs 1-2 months. Then the water evaporated raw fruits are sun-dried for 2 weeks to 1 month until the moisture is lowered to a water content of 15%. By using low temperature or freezing methods to process the raw fruits, the problem that the coffee is short in production and supply in a non-production period is solved, and the produced raw coffee fruit passes the standards of the Specialty Coffee Association of America (SCAA) in mouthfeel and taste, and thus may be referred to specialty coffee.

Description

[technical field] [0001] The invention relates to the technical field of coffee processing, in particular to a method for low-temperature freezing processing of coffee fruit. [Background technique] [0002] Coffee is grown in tropical regions between 24 degrees north latitude and 25 degrees south latitude. Coffee beans are divided into two categories, Arabica and Robusta. Arabica coffee beans are produced at an altitude of more than 800 meters, and Robusta coffee beans are produced at an altitude of less than 800 meters. Generally, the picking frequency is 1-2 times a year, and a picking season lasts for 3-5 months, so in general It is said that there will be a non-picking season for 3-4 months, which will lead to a decline in supply. For example, in the coffee-producing region of Aceh in Indonesia, the coffee picking season is divided into a large production period (May to September) and a small production period (November to January), so coffee production is almost at a s...
