Embodiment 2

[0056] The device for concentrating coffee stock solution in this embodiment is the same as that in Embodiment 1.

[0057] The production method of the coffee of the present embodiment, comprises the steps:

[0058] Step (1), roasting and grinding the green coffee beans to obtain ground coffee powder;

[0059] The green coffee beans are roasted, and the roasted Yunnan small-grain medium-roasted coffee beans are crushed into powder at normal temperature to obtain ground coffee powder.

[0060] Step (2), extracting ground coffee powder with cold water to obtain coffee slurry;

[0061] The ground coffee powder and water are contacted with water in the extraction tower according to the weight ratio of 1:3.3 to release the water-soluble substances.

[0062] Step (3), solid-liquid separation of the coffee pulp to obtain coffee grounds and coffee stock solution;

[0063] The coffee pulp is separated into coffee grounds and coffee liquid by high-speed centrifugation.

[0064] In s...

Abstract

The invention relates to a coffee stock solution concentration device and a production method of flash reduction coffee. The device comprises a freezing chamber, a refrigerating tank is arranged in refrigerating chamber; the freezing tank communicates with a steam conveying pipe and a coffee stock solution conveying pipe; a temperature sensor and a liquid level sensor are arranged in the freezingtank; the lower end of the freezing tank extends out of the freezing chamber; the bottom end of the freezing tank communicates with a liquid outlet funnel; a receiving container is arranged at the lower end of the liquid outlet funnel; the temperature sensor and the liquid level sensor are connected with a PLC; and a refrigerating device communicates with the freezing chamber. The concentration device is used for concentrating the coffee stock solution before freeze drying, so that the finally obtained flash reduction coffee powder is high in recovery degree, rich in fragrance and clear in soup color, original components, fragrance and flavor in coffee are fully reserved, and the original flavor of freshly ground coffee is perfectly recovered.

Description

technical field [0001] The invention relates to a concentrating device, in particular to a coffee stock solution concentrating device that maintains the original flavor of coffee, and also relates to a production method of flash-dissolved reduced coffee, which belongs to the field of coffee-like solid beverage processing. Background technique [0002] Coffee is usually sold in both roast and ground and instant coffee. [0003] Traditional coffee brewing is to use roasted coffee beans, grind them on site, and use a percolator to brew them. During the brewing process, they are filtered through filter materials such as filter paper (filter cloth) to filter out residues and obtain taste and flavor. Excellent freshly ground coffee. [0004] Instant coffee is to make the brewed coffee liquid into dry powder by spray drying or conventional low-temperature drying method, and obtain instant coffee that is ready to drink when drinking. [0005] Traditional freshly ground coffee has ...
