Project Brief:
Dehydrated vegetable special production line is in traditional mesh belt type drier dedicated research and development on the basis of the type dry production line, widely used in all kinds of regional and seasonal vegetables, fruit dehydration, drying cassava chips, garlic, pumpkins, and the Chinese wolfberry, tablets, carrots, konjac, mountain bamboo shoots, horseradish, onion, apple, sweet potato, eggplant, potatoes, tomatoes, candied fruit, chestnut, tea, shredded radish, turnip, mint, Melissa, chives, rose, lavender, shrimp, dried small shrimps and ideal equipment.
So far, according to user requirements have been successfully developed: DW series single-layer mesh belt type drier, Three - layer mesh belt type drier, five layer mesh belt type drier, seven layer mesh belt type drier, and the flap type mesh belt drier.
Working principle:
1, consists of feeder hopper in the material by the conveyor belt evenly in the network, network using 12 to 60 mesh stainless steel wire mesh, drag in the drier move by the transmission device. Drying section consists of a number of independent loop into unit group, part of the tail gas by dedicated platoon is wet exhaust fan, each unit discharge gas regulating valve control. In the circulation unit, wind circulation fan out from the side duct into the inferior vena, air flow upwards through the Heat exchanger to Heat, and after allocator, blowing into jet mesh belt, through the material back into the cavity. Drying process is the hot air flow through the material layer, heat and mass transfer process. Part of a cavity by duct connected with fan inlet, gas cycle, part of the high temperature low moisture content of gas as the platoon is wet exhaust pipe, regulating valve, the platoon is wet exhaust fan. Cycle unit, under the circulation fan out on the wind into the first chamber, inferior vena connected with fan inlet by side air duct and back to duct, most of the air circulation, part of the discharge, up and down cycle unit according to user needs can be equipped with a flexible, unit number can be selected according to need.
2, used in Dehydrated vegetable, generally using three sets of equipment series, formed in the early period, middle period and final dry section. In dry in the early period, due to their high material moisture, permeability is poor, so by laying the material thickness of small, fast running speed and the higher the drying temperature. For material temperature does not allow more than 60 ℃, dry in the early period, dry gas temperature can be as high as 120 ℃ below, in the dry material Residence time is dry in the early period of 3 to 6 times, spread the thickness of the material is dry in the early period of 2 to 4 times. To the requirement of material temperature does not exceed 60 ℃, 80 ℃ can be used dry gas. Using multistage combination can better play to the performance of the belt type drier, more uniform and dry.
Advantage of project:

Can be designed according to different drying material properties, short drying time, low energy consumption, good quality, conform to the requirements of the state food and health, so as to bring new opportunities for the industrialization development of agricultural and sideline products.
