Product Description

3. Microwave overview
Microwaves are electromagnetic waves with frequencies ranging from 300MHz to 300GHz. By water molecules in the heating medium is a polar molecule, polar water molecules in the fast development of the high frequency electromagnetic field under the action of the polar orientation will change with the external electric field, resulting in the movement of molecules and mutual friction effect is also called heating effect. Microwave heating mainly causes the water molecule to cause strong polarity oscillation, friction and heat generation under the action of the microwave alternating electromagnetic field, so as to achieve the purpose of drying material. This process and have an effect on organisms, rupturing the capacitive structure of cell membrane, or between cellular and molecular hydrogen bond relaxation and other damage, the most basic unit cell bacteria living environment destruction and death, so as to achieve the purpose of sterilization. Therefore, microwave heating technology is generally applied to water containing medium. Basically, plants and animals are the media containing moisture, so microwave heating technology should be used in food and medicine (especially Chinese herbal medicine) processing industry. Of course, in the chemical industry, metallurgy and other industries also have its application. Now, microwave heating, as a new technology, has been paid great attention and applied in various fields.
4. Advantages of microwave heating technology
4.1 heat quickly
Microwave heating, unlike traditional heating methods, does not require heat conduction and can achieve heating temperatures in a very short period of time.
4.2 heat evenly
No matter the shape of each part of the object, the electromagnetic wave (microwave) can be absorbed at the same time in the object to produce heat energy. Unlike traditional heating methods, the phenomenon of defocus occurs.
4.3 energy efficient
Because of the moisture content of the material to easily absorb microwave heating, so in addition to a small amount of transmission loss, almost no other loss, so high thermal efficiency, energy saving. It saves more than 1/3 energy by far infrared heating.
4.4 mildew proof, antiseptic and fresh keeping
Microwave heating has thermal and biological effects and can be sterilized and mold at lower temperatures. Because the heating speed is fast and the time is short, the activity of the material and the vitamins, the original color and the nutrients in the food can be preserved to the utmost extent.
4.5 easy to control
Immediate heating and termination can be achieved only if microwave power is controlled.
4.6 safe and harmless
Because the microwave is controlled in the container made of metal and in the waveguide, the microwave leakage is effectively prevented. No radiation hazards and harmful gas emissions, no waste heat and dust pollution, that is, no pollution of food, nor pollution of the environment.

5. Equipment structure features
This equipment is a tunnel type microwave drying equipment. It is composed of microwave heater, microwave generator, microwave suppressor, mechanical transmission mechanism, cooling system and control operation system. The main components of the equipment are made of stainless steel and conform to the GMP standard of pharmaceutical equipment. The whole machine adopts modular design, and it is convenient to wash, assemble, disassemble and overhaul.
5.1 microwave heater is composed of a plurality of unit heating boxes, each of which is composed of a plurality of magnetron combinations. Magnetron for Samsung Corp production, the use of cooling water jacket cooling, long life; the use of microwave switching power supply, easy maintenance and low failure rate. Each unit heating box has a plurality of microwave input energy feeding ports, and the advanced design makes the interference between the feed energy ports extremely small. The microwave generator is composed of multiple independent control circuits, each equipped with a magnetron current overload protection device correspondingly, its characteristic is the power to choose flexible, uniform heating, easy to operate, can work separately according to the needs of users.
5.2 in the import and export of equipment are equipped with microwave suppressors, to ensure that microwave leakage in line with national safety standards.
5.3 transmission mechanism adopts Teflon chain conveyor belt, its speed regulation is stepless variable frequency speed regulation, frequency converter for Taiwan Delta company production, accurate control, stable performance.
5.4 the cooling system is the cooling of each heating element. The microwave tube is water-cooled, the electric controller is air-cooled, and the microwave switch power supply is air cooled. The cooling effect is good, and the service life of the microwave tube and the electrical component can be prolonged.
5.5 the machine by a unified control console, using delta Matsushita man-machine interface, PLC control, simple operation, easy to use; the main heating box is equipped with infrared radiation thermometer, temperature measurement accuracy, stable performance, can set the temperature control points, using this function can realize the automatic temperature control, can accurately control the quality of products set current; monitoring; magnetron device provided with a door automatically cut off to ensure safety.

7. Control system instructions
7.1 main control components
This system adopts a color touch screen as man-machine interface; the FP sigma series programmable controller (PLC) as the control unit; Taiwan Delta B series inverter; automatic adjustment of German imports of infrared thermometer temperature and power system.
7.2 system functions and advantages
7.2.1 this system adopts PLC control, and the system reliability is fully guaranteed. PLC speed can be complex mathematical model, to realize the automatic adjustment system of temperature memory power; on the production process of the same material, just a set of process parameters, can be continuous or interval of production, convenient operation, improve production efficiency. Microwave tubes can be selected according to the power requirements, turn work, and extend the service life. Also according to the location of the material, automatically switch the corresponding microwave heating group, without the use of false load, convenient operation, reduce pollution.
7.2.2 touch screen can display: the total power of the system, set the various process parameters, can also operate, including microwave heating group switch, conveyor belt speed on the touch screen operation is completed, convenient, intuitive and reliable. The touch screen not only controls the work of the heating box of each group, but also outputs the alarm signal of high temperature.
7.2.3 PLC can control the microwave heating group according to the temperature. The automation of the system is improved. Each switch of the microwave heating box can be completed separately on the touch screen, which is convenient and safe, and can ensure the stable performance, long service life and low failure rate of the system.
7.2.4 The speed of conveyor belt is controlled by frequency converter, and the line speed can be set on the touch screen, so that the belt can realize stepless speed regulation.
