Production equipment and method of high-concentration coffee liquid

Abstract

The invention discloses production equipment for high-concentration coffee liquid. The equipment comprises a soaking tank bracket, wherein a soaking tank is mounted at the upper end of the soaking tank bracket; a stirring device is mounted on the inner side of the soaking tank; a weighing conveying belt is arranged above the soaking tank; and a grinding machine is arranged above the weighing conveying belt. According to the production equipment and method of the high-concentration coffee liquid, the technological process is simplified, the technological cost is reduced, and the loss of materials in the complicated technological process is reduced. The equipment not only can obtain the highest dissolution rate so as to obtain the highest yield, but also can obtain high-concentration coffee liquid without concentration, and the dissolution rate of effective components is higher than 90%, the concentration (TDS concentration) of a high-concentration coffee solution is larger than 16%, the water content of coffee grounds is smaller than 10%, the yield exceeds 25% and is far higher than the current yield of 10-15%; moreover, the original components and fragrance in coffee are fully reserved, especially rich lipid substances are obtained, and the taste of coffee products is more mellow.

Description

technical field [0001] The invention relates to the field of coffee production, in particular to a production equipment and method for high-concentration coffee liquid. Background technique [0002] The production equipment of high-concentration coffee solution is the production equipment of coffee deep processing, which is used in the production of high-concentration coffee solution. [0003] The existing high-concentration coffee liquid is concentrated from low-concentration coffee liquid. The coffee concentrate is obtained by traditional brewing method to obtain low-concentration coffee liquid containing dregs. After filtering or centrifuging for solid-liquid separation, a low-concentration coffee solution is obtained. Evaporation, vacuum concentration or freeze concentration are then used to gradually concentrate the lower concentration coffee solution into a higher concentration coffee liquid. The process of concentrating a low-concentration coffee solution into a high...

AI Technical Summary

Problems solved by technology

The process of concentrating a low-concentration coffee solution into a high-concentration coffee solution is complicated, the process consumption and workload are large, and the yield is low (the yield of soluble solids is about 10%-12%), and the lipids in coffee are effective. Most of the ingredients are not separated out, and the separated part is also lost during the concentration process, so that the coffee brewed with the coffee concentrate, or the instant coffee produced with the coffee concentrate, almost completely loses the flavor of the coffee. and taste

In order to meet the market demand, manufacturers can only add flavoring agents or spices in the production process to prepare a taste acceptable to the market. The espresso liquid produced in this way loses the original flavor of coffee due to the lack of active ingredients in coffee. The products produced by adding, blending, etc. are of poor quality and are widely criticized. Therefore, the industry needs a convenient production equipment that can produce high-concentration coffee liquid without concentration.
