China Drying Network China Agricultural Mechanization Science Research Institute's 2011 agricultural science and technology achievement conversion project “Hot Air Microwave Vacuum Combined Drying Technology and Equipment Pilot Test†achieved initial results. The project adopted microwave drying chamber and vacuum chamber integrated design, square microwave drying chamber structure, tank insulation and rapid exhaust vacuum system, tray in and out of materials and plastic chain plate conveyor device, breaking the microwave energy matching between the unit segments The technology, its matured continuous microwave vacuum drying equipment is highly reliable and compatible, which increases the production capacity. The results of the project were tested and demonstrated by Mudanjiang Kangwei Food Co., Ltd. The hot air microwave vacuum combination drying technology for apple, carrot and shiitake was obtained, and the above-mentioned hot air microwave vacuum combination drying process for fruit and vegetable, equipment and engineering was completed. integrated. The project has developed 1 new equipment, established 1 pilot line, developed 3 new technologies, applied for 1 invention patent, and realized sales revenue of 1.5539 million yuan, tax revenue of 107,100 yuan, net profit of 327,400 yuan, with good economic benefits. And promote the application prospects.
Modular type
Asphalt Mixing Plant
1, mixing purely modular design, transportation, installation quick and
easy, large waste, spillage separation, novel and unique structure.
2, the dispenser ring belt feeder, frequency control, height adjustable,
unique structure for easy replacement of the belt, the feed more smoothly,
reducing the power consumption and with no warning lights, convenient for
customers.
3, efficient insulation of the drying drum, the special form of leaves and
curtains to make the heat exchange more fully, coupled with efficient
energy-saving imported burners, heavy, diesel dual-use, saving energy
consumption.
4, Vibrating Screen using vibrating body external linear closed structure,
high screening efficiency, easy maintenance, replacement screen, imported
bearing shaft more reliable.
5, the hot aggregate bin equipped with continuous level device, the
operator can be clear at a glance, and the aggregate used in the measurement of
the second measurement of the door, greatly improving the measurement accuracy.
Special structure of the material door, not easy to card material, work more
reliable .
6, Adopt European technology to design mixing main engine, double-decelerate
motor, high-speed end synchronization. Said good asphalt, the pump is directly
sprayed into the mixing pot, the powder is sprinkled into the mixing pot by
spiral to make the mixing more uniform and rapid. There are wood fiber add
interface and the old material regeneration entrance.
7, the dust removal system uses imported Nordex bags, the concentration of
dust emitted to the atmosphere less than 50mg / Nm3, fully meet the national
environmental requirements. Blowing down the dust, the powder into the
recycling powder cans, re-use, to avoid secondary pollution.
8, the control system uses today's leading industrial automation SIEMENS
overall solution, the use of PROFIBUS field bus to form a large distributed
automation system, in the mode of operation, the use of dual-industry computer
hot backup, dynamic display, no buttons, By the mouse to complete a variety of
operations, real-time fault monitoring and control, with parameter settings,
data management, fault diagnosis and other functions. Accurate measurement can
be achieved automatically, semi-manual and manual control, stable and reliable
performance.
