The initial mass of the preparation is 500g, the real-time mass is 400g, then:

water loss rate = (500-400)/500 × 100% =20%.

S343: and acquiring a preset water loss rate of the preparation and a preset total preparation time corresponding to the preset water loss rate.

The preset water loss rate of the preparation is determined according to the type of the preparation, and the total preset preparation time corresponding to the preset water loss rate is determined according to the temperature and the humidity of the preparation environment of the preparation, the initial mass of the preparation and the preset water loss rate.

For example, if the preset total preparation time of the preparation is 18 hours and the preparation time is 6 hours, then:

remaining preparation time length =18h-6h =12h

the remaining preparation process specific gravity = remaining preparation time length/preset total preparation time length × 100%

For example, if the remaining preparation time of the preparation is 12 hours and the preset total preparation time is 18 hours, then:

For example, if the predetermined water loss rate of the preparation is 60% and the water loss rate is 20%, then:

the remaining preparation process specific gravity = (60% -20%)/60% × 100% =67%

S346: and when the first difference value of the preset water loss rate and the water loss rate of the preparation is within a first preset range, and/or when the preparation time length of the preparation is not less than the total preset preparation time length, prompting a preparation completion result of the preparation.

Wherein the first preset range is a fault tolerance range which does not affect the preparation quality of the preparation, such as-2% -2%.

Optionally, the preparation completion result of the preparation can be prompted by a progress bar flashing or voice mode.

Since the water loss rate and the preparation time length of the preparation are obtained by calculating the interval set time, the water loss rate may not be the preset water loss rate, and the preparation time length may not be the preset total preparation time length, whether the preparation of the preparation is finished is judged by judging whether a first difference value between the preset water loss rate and the water loss rate of the preparation is within a first preset range or not and/or whether the preparation time length of the preparation is not less than the preset total preparation time length or not.
