15kw Tunnel Microwave Sterilizing and Drying Machine for Food

Brief Introduction:
WMG series microwave sterilizing & drying machine is a multi-pipe tunnel mode, which can be divided into horizontal Model WMG, vertical Model LWMG and track-type Model GWMG etc. It adopts our companys many patent technologies, such as PLC controlling system, upending and stirring mechanism, and anti-sliding mechanism etc. Over 90% surfaces of the machine are made of stainless steel. Its core electronic components are imported with original packing. The machine is mainly composed of electric-heating pre-heated oven, microwave heater, microwave suppresser, blower and dehumidifier monitoring system, mechanical drive mechanism, and pioneer PLC automatic control. Microwave heater consists of several units of heating boxes. The whole machine adopts modular design, resulting in convenient cleaning, installation, disassembly, inspection and repair.

 

Characteristics:
Magnetron is made by Japan Panasonic Company and it can be divided into water cooling and air cooling. In addition, microwave transformer can adopt such two kinds of structures too, resulting in easy maintenance and low failure rate. There are several microwave feed in entrances in every unit of heating box and mutual interference between them is extremely slight thanks to the advanced design. Microwave signal generator is constituted by several independent power control circuits. Every magnetron is controlled independently by an overload current safeguard and it can work separately according to the clients need. There is a microwave suppresser installed at the entrance of the machine, ensuring the leakage of microwave conforms to the national safety standard. Teflon closely-woven conveying belt with guide rail is adopted, which is safe, nontoxic and works steadily. The speed adjustment of conveying belt is speed control by frequency variation. Transducer is produced by Japan Panasonic Company and it has precise control and stable performance. On the top of every unit of heating box there is a fume capture arm and flange connecting is left, which can be accompanied with clients own ventilator and xerantic system. As a result, water vapor discharged by materials of heating box can be vented in time, ensuring well drying effect.

 

Besides, heating boxes are equipped with infrared radiation thermometer imported from the United States, which is noted for precise measurement and stable capacity. Utilizing this function, the machine can realize automatic adjustment of temperature and thereby precisely control the quality of products. The machines core components are all made of famous foreign companies with reliable quality and long life, such as Siemens, Mitsubishi and ABB etc. Furthermore, by adopting the agreed standard of microwave industry, some large-scale, mini-type, widening, multilayer and heightening etc. form of equipments can be customized according to the clients requirements

 

Main Technical Parameters:

 Agricultural machinery parts investment casting is one branch of Alloy Steel Precision Casting, which is widely used in agricultural machinery markets. Casting of agricultural machinery parts adopts lost wax casting, also called investment casting. 

 In wax pattern process,we mix stearic acid and paraffin wax. In wax pattern making, as you know, it is better than polyethylene, and the wax deformation is small. In dipping slurry process,most of the suppliers adopt water glass technics in domestic area,but we adopt compound technics or silica sol technics.

 In shell making,we adopt automatic sand-covering production line, which was invented under the guidance of our general manager.The indoor temperature was controlled by air-conditions,keeping the temperature at  24℃±1℃, which can make the castings much more stable,the internal tissues much more well-proportioned.

 In dewaxing process,about 95% of the castings suppliers adopt the original water dewaxing technics,but we using the advanced steam dewaxing technics,which we are very proud of.This can effectively avoid the air-hole and sand-hole,making the casting look much nicer.

 In smelt process,we use middle frequency furnace,avoiding the emergence of the oxide; in molten steel control part,we use Germany-imported direct reading spectrometer machine,assuring its quality before the molten steel out of the furnace.During this process we use ERP production and management software to get the feedback information.

 In heat treatment process,we use electric furnace,and adopt double-temperature control in order to heat the products equally.As a result, the products will have great metallurgical structure.

 Our tolerance can reach at the grade of 5-7 according to our country`s tolerance standard.

 In machining process,we have 12 CNC machining centers and some other machines, so we can make further machining if the customers need.

 Our Agricultural Machinery Parts casting has quality assurance in accordance with ISO9001: 2008, strict material inspection and exact dimension control, with 100% quality control. OEM order is welcome. The investment cast of  agricultural machinery parts can be made completely based on your specifications such as drawing, design, sample etc.
