Abstract

The invention relates to the technical field of coffee extraction equipment, and particularly relates to a solution low-temperature extraction device and an efficient extraction process thereof. The solution low-temperature extraction device comprises an extraction tank and a water inlet pipe. A water inlet pipe is communicated above the left end surface of the extraction tank; a stirring motor isfixedly connected on the upper end surface of the extraction tank; an adding device is fixedly connected on the right end surface of the extraction tank; the adding device comprises an adding hopperand a rotating cover, a rotating cover is rotatably connected on the left side of the upper end surface of the adding hopper, an air inlet pipe is communicated on the upper end surface of the rotatingcover, a first valve is fixedly connected on the outer side of the lower part of the adding hopper, and a quantitative rod is fixedly connected in the adding hopper. With the arrangement of the mainstirring shaft, the driven gear and the auxiliary stirring shaft, the stirring motor drives the main stirring shaft to rotate and the main stirring shaft drives the auxiliary stirring shaft to rotateso that irregular rotation of liquid in the extraction tank in forward and reverse directions is realized, sufficient and efficient mixing of the materials and the solution is guaranteed and normal operation of subsequent work is guaranteed.

Description

technical field [0001] The invention relates to the technical field of coffee extraction equipment, in particular to a solution low-temperature extraction device and an efficient extraction process thereof. Background technique [0002] Extraction refers to the transfer of a compound from one solvent to another by using the difference in solubility or distribution coefficient of the compound in two immiscible (or slightly soluble) solvents. After repeated extractions, the method of extracting most of the compounds and the way of coffee extraction have a great impact on the final quality of coffee. The extraction methods of each brewing equipment are different. Generally, the brewing of common equipment There are four methods: gravity, pressure, immersion, vacuum, etc. [0003] When coffee is extracted, it is necessary to mix the material with water first. Insufficient mixing will directly affect the subsequent extraction work and the quality of the coffee. The existing mixi...

Problems solved by technology

[0003] When coffee is extracted, it is necessary to mix the material with water first. Insufficient mixing will directly affect the subsequent extraction work and the quality of the coffee. The existing mixing generally uses a rotating device for stirring, while the existing stirring device generally It can only rotate in one direction, and the material and water source rotate in one direction due to inertia, which is not conducive to their full mixing. Therefore, a solution low-temperature extraction device and its high-efficiency extraction process are proposed to solve the above problems.
