Problems solved by technology

At present, the usual method for temperature detection is to record the temperature values ​​of the temperature sensor set in the cooking equipment at the start time point and the end time point, and directly calculate the difference between these two temperature values. Since the slurry is a large The temperature sensor can only detect the temperature of one point in the slurry. Obviously, this temperature detection method cannot accurately detect the temperature of the slurry. It is urgent for relevant technical personnel to develop a method that can accurately detect the temperature.

Embodiment 1

[0040] A method for detecting the temperature of slurry in cooking equipment. One or more temperature sensors are installed in the cooking device, and the temperature sensor is in direct contact with the slurry in the cooking equipment to detect the temperature of the slurry; figure 1 As shown, the method includes steps S101-S105:

[0041] S101. Heat the slurry to a preset first temperature T1 with a preset first power P1.

[0042] In the embodiment of the present invention, in order to accurately detect the temperature of the slurry in the cooking device, one or more temperature sensors need to be set in the cooking device in advance, and in order to accurately detect the temperature of the slurry, the temperature sensor needs to be able to communicate with the cooking device when it is set. direct contact with the slurry. Such as figure 2 As shown, it is a simple schematic diagram of the structure of the soybean milk machine, which includes a machine head 1 and a cup body...

Embodiment 2

[0074] The difference between this embodiment and the first embodiment is that the third temperature T3 may be the boiling point temperature of the slurry or the anti-overflow temperature.

[0075] Optionally, the third temperature T3 includes: a slurry boiling point temperature and an anti-overflow temperature.

[0076] In the embodiment of the present invention, when the third temperature T3 includes the slurry boiling point temperature and the anti-overflow temperature, the temperature measurement can have a standard according to the boiling point temperature and the anti-overflow temperature, which increases the accuracy of the temperature measurement, and the third temperature The temperature T3 is set higher, which can shorten the pulping cycle.

[0077] Optionally, when the third temperature T3 is the anti-overflow temperature: t=t-Δt, Δt is the time from the foaming of the slurry to the foam contacting the anti-overflow electrode; wherein, Δt=k*P+n; k , n is a constan...

Embodiment 3

[0081] The difference between this embodiment and the first embodiment is that the compensation of the temperature of the circuit board inside the head of the cooking device, the temperature of the motor and / or the temperature of the lower cover of the head of the cooking device to the calculation of the slurry quality is added.

[0082] Optionally, the energy conservation law includes: P*η*t=C*m*ΔT+ΔC;

[0083] Among them, P is the heating power within the temperature change ΔT time, η is the heating efficiency, m is the mass of the slurry, t is the heating time, C is the specific heat capacity of water, and ΔC is the mass compensation amount.

[0084] In the embodiment of the present invention, in addition to the energy absorbed by the slurry during heating, the heat absorption and heat dissipation of other components such as the head part will affect the measurement of m, so ΔC is added in the calculation of the slurry quality, that is, other components in the cooking equipm...

Abstract

The invention discloses a temperature detection method for thick liquid in cooking equipment. One or multiple temperature sensor(s) is / are installed in the cooking equipment, make(s) direct contact with the thick liquid in the cooking equipment, and is / are used to detec the temperature of the thick liquid. The method comprises that the thick liquid is heated to a preset first temperature T1 in a preset first power P1; the thick liquid is stirred for multiple times, and then a second temperature T2 of the thick liquid is detected; the thick liquid is heated to a preset third temperature T3 in a second power P2; the thick liquid is stirred for multiple times, and then a fourth temperature T4 of the thick liquid is detected; and time that the thick liquid is heated from the second temperature T2 to the third temperature T3 serves as heating time t, a temperature difference between the fourth temperature T4 and the second temperature T2 serves as a temperature rise value deltaT within the heating time t, and deltaT serves as a calculation parameter which is used to calculate the weight of the thick liquid via the law of conservation of energy.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of cooking equipment control, in particular to a method for detecting slurry temperature in cooking equipment. Background technique [0002] In the pulping process using cooking equipment, if cooking is carried out according to the amount of material and water consumption specified in the manual, the cooking equipment will heat the slurry to the preset temperature according to the preset time, according to the law of energy conservation (machine calorific value *Absorption efficiency = heat absorbed by the slurry), the slurry will also absorb a certain amount of heat according to the pre-calculated value; but if the amount of material added is reduced, the time for the cooking equipment to heat the slurry to the preset temperature will be reduced, and the heat absorbed by the slurry will also be reduced. will decrease; similarly, if the amount of material added increases, the time for t...
