Problems solved by technology

In the current technology, the switching of multiple pipelines inside the puree machine is realized through the rotary valve: firstly, the stepping motor is used to drive the rotary valve to rotate, and then the position sensor is used to detect the fixed rotation position, and the rotary valve is controlled to switch to the set position. Pipeline, the control method is relatively simple, when the sensor failure or detection failure cannot be found in time, it is easy to cause the risk of pipeline leakage or even scald customers
[0004] (2) In the current technology, when the internal rotary valve of the raw pulp machine is switched, the rotation of the rotary valve is simply controlled according to the set program, and the action of the rotary valve cannot be controlled in real time in combination with the actual situation in the pulping process to adapt to the pulping of the raw pulp machine Environmental changes ensure the reliability of the puree machine system, especially in order to better enhance the user experience and realize multi-functions in the current puree machine, some of them have a steam system. When steam is generated or steam is heated, if the valve is turned If the action is not timely or the action is too fast, the steam in the pipeline will not be discharged, forming a large internal pressure of the pipeline, which will reduce the service life of the pipeline in the slightest, and directly burst the pipeline in severe cases, posing a great safety risk
[0005] (3) At present, multiple pipelines in the puree machine system can be connected to each other through the rotary valve. When the rotary valve operates, it will inevitably pass through other pipelines and cause some non-purpose pipelines to be connected for a short time. If the rotary valve operates at an appropriate time and the action direction cannot adapt to the pulping environment of the original pulp machine in real time, which will cause the slurry to overflow or flow through other pipelines, which will not only cause the pipeline to be dirty, but also affect the pulping effect
[0006] (4) At present, the action of the rotary valve inside the raw pulp machine system is generally set in advance, which cannot guarantee the safe and reliable switching of the pipeline, and at the same time, the action of the rotary valve will be in place as soon as possible, shorten the action time of the rotary valve, and reduce the pulping cycle

Embodiment 1

[0048] A method for controlling a rotary valve of a food processing machine, such as figure 1 As shown, the rotary valve of the food processor includes: an up rotary valve and a down rotary valve. Switching between pulp mouth and pulp cup and waste water box, such as figure 2 As shown, the control method includes S101-S102:

[0049] S101. Detect the current state of the food processing machine; wherein, the current state includes a standby state and a working state.

[0050] In the embodiment of the present invention, in order to automatically determine the best action path according to the different states of the food processor, and to control the rotary valve of the food processor accordingly, to ensure safe and reliable switching of the pipeline, the action time of the rotary valve is shortened, and the In the pulping cycle, the current state of the food processor can be detected first to judge the switching working environment of the rotary valve.

[0051] In the embod...

Embodiment 2

[0076] In this embodiment, on the basis of the first embodiment, the stroke of the rotary valve is further limited.

[0077] Optionally, the method further includes: changing the position of the up-rotation valve according to the shortest stroke.

[0078] In the embodiment of the present invention, when the up-rotation valve is switched, the minimum action stroke can be selected to switch the up-rotation valve.

[0079] Optionally, the water inlet, sealing port, slurry discharge port and additional port are sorted counterclockwise;

[0080] Such as image 3 As shown, changing the position of the upturn valve according to the shortest stroke can include:

[0081] When the two ports that need to be converted are adjacent, without going through other ports, directly rotate clockwise or counterclockwise to turn the up-rotating valve to the target port position;

[0082] When the two openings that need to be converted are diagonal openings, the diagonal opening includes: the rel...

Embodiment 3

[0087]On the basis of the first embodiment, this embodiment provides a material detection embodiment scheme.

[0088] Optionally, the first water intake is the maximum pulping capacity;

[0089] Detecting whether there is material in the cup includes: based on the first water intake, detecting the motor current when the motor is working, and judging whether there is material in the cup according to the magnitude of the motor current.

[0090] In the embodiment of the present invention, the water intake of steam is the maximum capacity of pulping, which ensures that the water level in the cup is controlled at a fixed position regardless of whether it is due to the user adding water by mistake or the last round of abnormal power failure, so as to ensure a constant amount of material.
