In automation solutions on the spiral quick-frozen food

In automation in the food spiral quick-freezing machine solution reached the dentsu co. , LTD. Wang hao welcome to e exhibition hall 8 meat processing machinery/preservation equipment exhibition hall cutting machine, meat grinder, meat cutting machine, frozen machine, quick-freezing machine,. 。 。 Abstract: this paper mainly introduces in industrial automation products, especially DOP - B series touch screen of the application of new products in spiral quick-freezing machine solution, and the process implementation of spiral quick-freezing machine. Key words: machine PLC controller HMI 1 introduction originated in the United States of quick-frozen food in recent years, international growth rate as high as 20%, 30%. Quick-frozen food will become the world's fastest growing food, its sales in the developed countries will account for 60% of all food - 70%, had become processed foods instead of canned food monopoly of the first. At present, the existing production of quick-frozen food companies have nearly 200, more than 300 varieties, annual production capacity of 10 million tons. Quick-frozen convenient food exports more than Italy in the world first. China's frozen food cold chain from the manufacturer to the store and home has been formed, so with the improvement of people's living standard, to food hygiene, nutrition, the pursuit of fresh and convenience, etc, and quick-frozen food in an increasing share of international trade, quick-frozen food promising prospects. Frozen food is to the pretreatment of food, in 30 minutes pass - quickly 1℃— - 5 ℃ maximum ice area, then below - 18 ℃ under the environment of storage and transportation of food. Frozen food in our country appear on the market only ten years, but was regarded as the food industry for its rapid development trend of round of the rising sun. 2 sets of mechanical and electronic platform based control system for the spiral quick-freezing machine with compact structure, the advantages of wide scope of frozen goods and widely used in the industries of frozen. Spiral quick-freezing machine is frozen chicken, dumplings, dumplings, Fried food, flour products, such as shrimp, fish, meat and poultry products, aquatic products and the mainstream of small food packaging equipment. But how can you make the spiral quick-freezing machine ensure quick-frozen food technology to realize in the process of normal use, avoid too long when frozen, avoid frost crack problems is the key to the spiral quick-frozen food quick-freezing machine problem. 2. 1 PLC controller host chooses in DVP14SS11R2 PLC control center, as the control center of spiral quick-freezing machine, program control and communication of the command to send, peripheral switch signal acquisition and executive device control commands sent, formula of data storage, and other functions. Power supply module is chosen in DVPPS01, provide stable DC24V power supply for control system. PLC controller extension module selection in two DVP16SP11R acquisition DI/DO control signal. 2. 2 the man-machine interface man-machine interface of DOP - choose one B07 touch-screen, provide a good and friendly man-machine interface, can be the machine speed and the parameters of the formula through man-machine interface, the fault information, fan, water pump control, etc. 2. 3 temperature control temperature control in temperature control module DVP04TC - S, working temperature, the acquisition spiral quick-freezing machine can correct control system to produce high quality products, the collection of accurate temperature is critical. 2. Variable frequency drive variable frequency drive selection table 4 VFDS - 2 M055 frequency converter, a frequency conversion VFDS - M drive belts, another frequency VFDS - M to adjust conveyor belt balance, speed, balance, and other functions. Based on the electrical machinery platform spiral quick-freezing machine control system configuration framework is shown in figure 1. Figure 1 control system configuration 3 3 main function design. 1 automatic/manual control mode selection by the touch screen select automatic or manual control mode, as shown in figure 2. Figure 2 control mode selection can run automatically by selecting the corresponding set of parameters for automatic control operation, set up in a 'frozen temperature', and at the same time the 'speed' will be displayed in the 'speed of wimbledon belt' one. Will 'not wimbledon speed' and 'feed temperature' set after press 'start' to start the equipment, as shown in figure 3. Figure 3 automatic operating mode 3. 2 HMI recipe management because inevitably due to environment temperature, load, production efficiency and so on comprehensive factor changes, but the food in different temperature of frozen time is nonlinear relationship, so through the powerful formula in HMI function - different products in different temperature Speed setting, as shown in figure 4. Figure 4 HMI recipe management 4 conclusion project testing and trial production proved that in building automation control system platform can perfect, efficient, high quality to produce all kinds of packaging, including frozen chicken, dumplings, dumplings, Fried food, flour products, such as shrimp, fish, meat and poultry products, aquatic products such as food packaging. And with the electronic control system of high efficiency, mature, the application of high value in automation solutions, will provide more help for food machinery of upgrading, make greater contribution to society.
