Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically to a paste-like food cooking device. Background Technology

[0002] The cooking process of paste-like foods involves complex heat and mass transfer, phase change reactions, and dynamic evolution of rheological properties. Its process control must consider multiple factors, including temperature gradients, viscosity changes, and mixing uniformity. However, traditional cooking equipment has significant technical deficiencies in monitoring and controlling key parameters: existing equipment generally lacks the ability to monitor material viscosity in real time, relying on manual experience to judge the final product state. This results in process parameters failing to accurately respond to changes in material properties, leading to poor batch-to-batch quality consistency and shortened product shelf life. Furthermore, the fixed-speed design of the stirring mechanism cannot adapt to the dynamic changes in material viscosity from low to high during cooking, resulting in a contradiction between redundant energy consumption in the low-viscosity stage and uneven mixing in the high-viscosity stage, directly affecting product quality and energy efficiency. Utility Model Content

[0003] In view of the problems and shortcomings of the existing technology, this utility model provides a paste-like food cooking device.

[0004] The technical solution of this utility model is as follows:

[0005] A paste-like food cooking device includes a pot body, a support frame, a steam conveying component, a stirring mechanism, and a drive motor. The stirring mechanism includes a stirring shaft and an arc-shaped stirring frame, and the stirring shaft is driven by the drive motor.

[0006] It also includes a concentration detection module and a control system; the concentration detection module is used to detect the viscosity of the material in the pot in real time and feed it back to the control system; the control system dynamically adjusts the speed of the drive motor according to the viscosity data of the food being cooked; the concentration detection module includes a torque sensor, which is integrated between the stirring shaft and the drive motor and is connected to the intelligent control module to indirectly calculate the viscosity of the material by obtaining the stirring resistance torque.

[0007] The bottom of the stirring mechanism is equipped with an arc-shaped scraper that fits against the bottom of the inner pot body to prevent material from settling.

[0008] The control system includes a PLC controller and a frequency converter. The PLC controller receives signals from the concentration detection module and outputs control commands to the frequency converter, which adjusts the speed of the drive motor.

[0009] The control system is also equipped with an alarm module, which triggers an audible and visual alarm when the viscosity is detected to exceed a set threshold.

[0010] The concentration detection module also includes an ultrasonic sensor, which is fixed to the top edge of the pot body by a mounting plate, with the probe facing into the pot body, and calculates the viscosity of the material by the sound wave attenuation rate.

[0011] The drive motor is a variable frequency motor with a speed adjustment range of 20-150 rpm.

[0012] The drive motor speed is set as follows: 30-50 rpm for viscosity < 500 cP, 50-80 rpm for viscosity 500-2000 cP, and 80-120 rpm for viscosity > 2000 cP.

[0013] The pot body has a double-layer structure, with a steam chamber formed between the inner and outer pot bodies, and the steam conveying component is connected to the steam chamber.

[0014] The arc of the scraper matches the bottom of the inner pot body, and its edge is coated with a wear-resistant ceramic coating.

[0015] The arc-shaped stirring frame is equipped with detachable shovels, which are evenly distributed along both sides of the arc-shaped frame. The detachable shovels are composed of several sub-shovels, which are detachably fixed to the arc-shaped stirring frame by bolts.

[0016] The steam delivery assembly includes a steam input pipe, a solenoid valve, and a temperature sensor. The temperature sensor is connected to the control system to achieve closed-loop control of temperature and steam flow.

[0017] The beneficial effects of this utility model are:

[0018] This invention significantly improves the process stability and equipment reliability of the cooking process through viscosity dynamic sensing and intelligent adaptation of stirring parameters. Based on the material viscosity data monitored in real time by the torque sensor, the control system can automatically adjust the stirring speed. In the low viscosity stage, a low speed is used to reduce energy consumption, and in the high viscosity stage, the speed is increased to enhance the mixing effect, avoiding material splashing caused by local overheating due to insufficient stirring or excessive stirring.

[0019] Combined with the synchronous rotation design of the bottom arc-shaped scraper, it effectively inhibits the formation of deposits on the bottom of the pot, significantly reduces the deposit thickness, and brings the probability of scorching to near zero. At the same time, it reduces the frequency of cleaning and extends the service life of the equipment. Attached Figure Description

[0024] The technical means adopted to achieve the intended purpose of this utility model will be further described below with reference to the accompanying drawings of the embodiments of this utility model.

[0025] Example

[0026] See Figure 1 and Figure 2 The paste-like food cooking device of this utility model mainly consists of four parts: pot body 2, stirring system, heating system and control system.

[0027] The pot body 2 adopts a double-layer structure design. The inner pot body is used to hold materials, and a sealed steam chamber is formed between the outer and inner pot bodies. The steam delivery component supplies heating steam to the steam chamber through a steam input pipe, and the steam flow rate is controlled by a solenoid valve. A temperature sensor is installed at the bottom of the pot body to monitor the material temperature in real time and feed it back to the control system.

[0028] The mixing system includes a mixing mechanism 3 and a drive motor 4. The mixing mechanism 3 includes a mixing shaft 31, an arc-shaped mixing frame 32, and detachable scrapers 33. The drive motor 4 is a variable frequency motor, and its speed can be adjusted within the range of 20-150 rpm. The mixing shaft 31 transmits power to the arc-shaped mixing frame 32, on which the detachable scrapers 33 are mounted. The scrapers consist of several sub-scrapers, which are fixed to the arc-shaped mixing frame 32 with bolts for easy replacement and maintenance. The bottom of the mixing mechanism 3 is specially designed with an arc-shaped scraper whose curvature perfectly matches the bottom of the pot body 2, and its edge is coated with a wear-resistant ceramic coating to effectively prevent material deposition.

[0029] See Figure 1 The concentration detection module uses a torque sensor 5, installed between the stirring shaft 31 and the drive motor 4. The sensor monitors changes in the stirring resistance torque in real time and transmits the data to the control system. The system converts the resistance torque into a material viscosity value according to a preset algorithm. (See also...) Figure 2 As a supplement, the device can also be equipped with an ultrasonic sensor 6, which is fixed to the top edge of the pot body 2 by a mounting plate, with the probe facing the inside of the pot body 2. The viscosity of the material is calculated by the sound wave attenuation rate and verified with the data of the torque sensor 5.

[0030] The control system, centered on a PLC controller, receives signals from the concentration detection module and temperature sensor, and calculates the optimal stirring speed and heating parameters using a built-in control algorithm. The control system outputs commands to the frequency converter to adjust the drive motor speed; simultaneously, it controls the solenoid valve to regulate the steam flow. The system also includes an alarm module; when abnormal conditions such as excessively high viscosity or abnormal temperature are detected, an audible and visual alarm is triggered to alert the operator.

[0031] The working principle of the device is as follows: First, the raw materials are added to the pot 2, and the heating system is started. As the temperature rises, the material begins the cooking process. The torque sensor 5 monitors the changes in stirring resistance in real time, and the control system dynamically adjusts the stirring speed according to the viscosity data. In the early stage of cooking when the material is relatively thin, a lower speed of 30-50 rpm is used. As the viscosity increases, the speed is gradually increased to 50-80 rpm, and the highest speed of 80-120 rpm is used in the later stage when the viscosity is the highest. The arc-shaped scraper rotates with the stirring mechanism 3, continuously scraping off the material deposited at the bottom of the pot. When the predetermined cooking degree is reached, the system issues a completion signal, and the operator can proceed to the next step.

Within the scope of knowledge possessed by those skilled in the art, all variations, equivalent substitutions, and improvements made without departing from the concept of the present invention should be included within the protection scope of the present invention.
