Example Embodiment

[0038] The technical solutions of the present invention will be further described in detail below through the accompanying drawings and embodiments.

[0039] In the present invention, the existing pulse step heating method can be changed to the segmented pulse step heating method, and different heating coefficients are used in different time periods.

[0040] Such as figure 2 Shown is a schematic flow diagram of an embodiment of the method for controlling the temperature of the feeding tank of the present invention. In this embodiment, the temperature control process of the feeding tank includes:

[0041] Step 101: At each pulse heating in the process of pulse heating the feeding tank according to the preset period, the controller receives the real-time temperature detection value corresponding to this pulse heating sent by the temperature sensor;

[0042] Step 102: The controller determines the corresponding heating coefficient according to the value range of the difference between ...

Abstract

The invention relates to a feeding tank temperature control method and system. The method includes the steps that in each time of pulse heating in the process of pulse heating on a feeding tank according to a preset period, a controller receives a real-time temperature detection value sent by a temperature sensor and corresponding to the time of pulse heating; the controller determines corresponding heating coefficients according to numerical ranges where difference values between a process set value and the real-time temperature detection values are in, wherein the numerical range where a smaller difference value is in corresponds to a smaller heating coefficient, and the numerical range where a larger difference value is in corresponds to a larger heating coefficient; the controller calculates the heating temperature adopted in a next time of pulse heating according to the difference values and the corresponding heating coefficients, and the next time of pulse heating is carried out according to the heating temperature. The feeding tank temperature control method and system can overcome shortcomings existing in impulse type step-by-step heating in the prior art, improve feed liquid heating efficiency and enhance heating effects.

Description

technical field [0001] The invention relates to the field of tobacco processing, in particular to a method and system for controlling the temperature of a feeding tank. Background technique [0002] Feeding is an important part of the tobacco production process, and one of the important process indicators is the temperature of the feed liquid, which is related to the quality of tobacco products. The control of the feed liquid temperature is affected by various factors in the production process, such as uneven stirring of the feed liquid, temperature changes in the workshop, poor drainage of condensed water, unstable heating steam pressure, etc., resulting in large changes in the feed liquid temperature control curve, which is difficult Meet the technical requirements (for example, the process requires about 50°C), which will greatly affect the taste and quality of the tobacco leaves. [0003] The existing temperature control method of the feeding tank adopts the pulse-type ...
