Embodiment Construction

[0015] The present invention will be further described in detail through specific embodiments below.

[0016] Before the present invention is discussed in detail, it is necessary to describe the existing coffee machine as follows:

[0017] Existing coffee machines include fully automatic coffee machines and semi-automatic coffee machines, and this automatic coffee machine also needs manual operation during use. The coffee machine used in the embodiment of the present invention is a semi-automatic coffee machine. Wherein, the semi-automatic coffee machine is equipped with a heating furnace, and the heating furnace is connected to the external brewing head. After the water is heated by the heating furnace, it can be output from the brewing head. The water inside is pressurized. The brewing head is also provided with a corresponding structure for extraction to extract the ground coffee.

[0018] Wherein, heaters such as heating rods are arranged in the heating furnace, and the...

Abstract

The invention provides an intermittent heating method for coffee brewing. The intermittent heating method includes following steps: acquiring water temperature in a heating furnace in real time; when a temperature difference between the water temperature and rated temperature reaches a first temperature difference value, driving a heater to continuously heat for first preset heating time, and stopping heating for first preset stopping time; judging whether the water temperature reaches the rated temperature or not; if not, lowering the first temperature difference value, shortening the first preset heating time and the first preset stopping time, and repeating the above steps until the water temperature reaches the rated temperature. By the intermittent heating method, the water temperature can be prevented from being too high or too low, so that constancy of the water temperature is controlled, fluctuation range of the water temperature is narrowed, and guaranteeing of taste of coffee after extraction is facilitated.

Description

technical field [0001] The application relates to the field of food technology, in particular to an intermittent heating method for brewing coffee. Background technique [0002] With the improvement of people's material living standards, more and more people are getting used to drinking coffee, but the taste of coffee often requires professional brewing methods. As a machine dedicated to brewing coffee, the coffee machine realizes the automatic control of the whole process of brewing coffee, such as grinding, pressing, filling, brewing, and removing residues, and is very convenient to use. [0003] Generally, before brewing coffee, the coffee machine needs to extract the coffee so as to refine the coffee and improve the taste of the coffee. However, in the existing method, the coffee is usually directly extracted, because the equipment requires that the water temperature be kept constant in the range of 89-92, but the extraction needs cold water to be injected into the boil...
