It integrates electronic technology, mechanical technology and extraction technology, and realizes the control of the entire process of brewing coffee, from grinding, pressing, filling, brewing to removing residues. Coffee extraction is a key link in the coffee making process, which involves extracting soluble substances in coffee powder into water to form coffee liquid. The system that integrates coffee liquid extraction and processing refers to equipment or devices that can complete a series of operations such as coffee extraction, filtration, coffee grounds collection and processing. There is a great demand in the market, but the traditional system still has the following shortcomings in actual use: (1) During the preparation of cold brew coffee, long-term extraction and storage lead to abnormal microbial indicators in the coffee liquid in the coffee machine, thus affecting the taste of the coffee liquid and even causing effects on the drinker's health.

[0003] (2) In the process of preparing traditional cold brew coffee, the temperature of the coffee liquid after extraction will be higher than the normal temperature, which will affect the taste of the coffee liquid after it is taken out to a certain extent.

[0004] (3) In the traditional cold brew coffee machine system, the coffee liquid and the coffee liquid stored in the coffee machine are discharged through the same outlet, which is prone to the hazard of bacterial cross-infection between the food pipeline and the waste liquid pipeline. Therefore, the outlet and pipeline must be cleaned separately after each discharge, which is time-consuming and labor-intensive. Summary of the invention

In this embodiment, the first direction is a direction perpendicular to the operation panel 9.

[0043] Accordingly, the present invention also provides a processing method, which is applied to the above-mentioned system for preparing an extracting solution, and the processing method includes the following parts: Specifically, in this embodiment, the processing method has three different processing modes, including the following parts: Circulation treatment, the circulation treatment includes the following steps: under the action of the controller 8, the first ball valve 308 is adjusted to make only the third branch pipe 3013 and the fourth branch pipe 3014 connected.

After the water inlet is completed, the solenoid valve 7 is adjusted to keep only the first branch pipe 3011 and the fifth branch pipe 3015 connected, and the circulation extraction is performed under the action of the pump 4, the refrigerator 5 and the sterilizer 6. The coffee liquid flows through the first branch pipe 3011, flows through the second branch pipe 3012 through the pump machine 4, flows through the third branch pipe 3013 through the refrigerator 5, flows through the fourth branch pipe 3014 and is sterilized in the sterilizer 6, flows into the tube body 11021 through the conversion part 12, flows into the liquid storage barrel 10 through the orifice 110211, and flows into the fifth branch pipe 3015 through the conversion part 12. The fifth branch pipe 3015 is connected with the first branch pipe 3011, thereby forming a cycle. After multiple comparative tests, under the same conditions of controlling raw materials, time, water volume, etc., the extraction rate is compared. The circulation treatment and extraction liquid structure provided by the system of the present invention can obtain a higher extraction rate for the produced coffee liquid. The higher the extraction rate, the more coffee flavor substances are extracted. For the same coffee powder, the higher the extraction rate, the higher the yield rate, as shown in Table 2 below: Table 2

[0045] When coffee liquid flows in from the fifth branch pipe 3015, it is discharged from the first branch pipe 3011, the second branch pipe 3012, the third branch pipe 3013, the sixth branch pipe 3021 and the seventh branch pipe 3022 in sequence under the action of the pump 4 and the refrigerator 5.

[0046] Drainage treatment: The drainage treatment includes the following steps: under the action of the controller 8, the first ball valve 308 is adjusted so that only the third branch pipe 3013 and the sixth branch pipe 3021 are connected, and the second ball valve 309 is adjusted so that only the sixth branch pipe 3021 and the drainage pipe 303 are connected.

[0047] When coffee liquid flows in from the fifth branch pipe 3015, waste liquid is discharged in sequence through the first branch pipe 3011, the second branch pipe 3012, the third branch pipe 3013, the sixth branch pipe 3021 and the drain pipe 303 under the action of the pump 4 and the refrigerator 5.

[0048] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
