Embodiment Construction

[0048] In order to facilitate the understanding of those skilled in the art, the specific implementation steps of the present invention will be further described below in conjunction with the drawings and embodiments.

[0049] The specific implementation of the present invention can be divided into four steps: measurement system construction, sensor information processing, determination of index reference range and quality evaluation information feedback. figure 1 It is a diagram of specific implementation steps.

[0050] The first step is to build the measurement system, and install weighing modules, thermal resistors, thermocouples, pressure gauges, and visual sensors on ordinary coffee machines. The weighing module is used to measure the weight of the coffee liquid flowing from the coffee machine; the thermal resistance is used to measure the boiler temperature; the thermocouple is used to measure the temperature of the coffee liquid at the outlet of the coffee machine; the...

Abstract

The invention discloses a soft-measurement method of quality of espresso coffee. A sensing information measurement system is built on a coffee machine. The sensing information measurement system includes a weighing module, a thermal resistor, a thermocouple, a pressure gauge and a vision sensor. The thermal resistor is used to measure temperature of an outer wall of a boiler. The thermocouple is used to measure temperature of coffee liquid of an outlet of the coffee machine. The pressure gauge measures pressure of the outlet of the pump. The visual sensor is used to obtain color information ofthe coffee liquid of the outlet. Sensor information is processed, and indexes of average boiler temperature, average outlet temperature, time in which the outlet temperature reaches a stable state, water discharging time, brewing-boiling duration, average pressure, an average flow rate, time in which a flow rate reaches a stable state, coffee outlet color changes and the like are calculated. Upper / lower-limit reference ranges of the indexes are determined through historical statistics of the coffee sensor information and a coffee extraction process mechanism. A priori statistical knowledge iscombined for soft measurements on the quality of the espresso coffee, and arbitrariness and empirical dependence of human tasting are eliminated.

Description

technical field [0001] The invention belongs to the technical field of coffee machines, in particular to a soft measuring method for the quality of espresso coffee. Background technique [0002] China's coffee market has gradually expanded in recent years. Among them, espresso is a kind of high-pressure extracted coffee, which means that hot water flows through the roasted and ground coffee under a pressure of about 9bar, and the coffee powder is washed and dissolved by mechanical washing. The substances in the coffee are extracted into hot water to form an espresso drink. [0003] The coffee machine has been continuously improved for nearly a century, and the production process and mechanical design have been very mature. Coffee machines generally include water tanks, boilers, pumps, brewing heads, powder bowls and other parts. The cold water in the water tank is drawn into the boiler under the action of the pump for heating. When the coffee machine is working, the pump ...
