Project Overview:
1. The special production line for dehydrated vegetables is a special-purpose drying production line researched and developed on the basis of traditional mesh belt dryers. It is widely applicable to the dehydration and drying of various regional and seasonal vegetables and fruits. It is dried cassava chips and garlic flakes. Pumpkin, wolfberry, carrot, konjac, yam, bamboo shoots, horseradish, onion, apple, sweet potato, eggplant, potato, tomato, candied, chestnut, tea, radish, radish, mint, honeybee, fine Ideal equipment such as chives, rose, lavender, shrimp, shrimp, and so on.
2. I Jiangsu Zhenxing Drying Equipment Co., Ltd. is the most experienced vegetable drying equipment manufacturer in China. The technicians have long-term follow-up services to users, in-depth user debugging, first-hand practical information and combined with domestic advanced technology, continuous improvement and Improve the equipment. So far, according to user requirements has been successfully developed: DW series single-layer mesh belt dryer, three-layer mesh belt dryer, five-layer mesh belt dryer, seven-layer mesh belt dryer, and flap type network With dryer.
working principle:
1. The material in the hopper is evenly laid on the mesh belt by a feeder through a conveyor belt. The mesh is made of a 12-60 mesh stainless steel wire mesh and is moved by a transmission device to move in the dryer. The drying section is composed of several hot air independent circulation units. Part of the exhaust gas is discharged by a special dehumidifying fan. The exhaust gas volume of each unit is controlled by a regulating valve. In the upper circulation unit, the wind from the circulation fan enters the lower chamber through the side air ducts. The airflow is heated upwards through the heat exchanger and distributed by the distributor. The jet is blown into the mesh belt, passes through the material and enters the upper chamber. The drying process is a process in which hot air flows through the material layer to complete the heat and mass transfer. The upper chamber is connected to the inlet of the fan by the air duct, and part of the gas is circulated. Part of the air with lower temperature and higher moisture content is discharged as exhaust gas through the dehumidifying pipe, the regulating valve and the dehumidifying fan. In the lower circulation unit, the wind from the circulating fan enters the upper chamber first, and the lower chamber is connected with the inlet of the fan by the side air duct and the return air duct. Most of the air circulation and part of the air circulation are discharged. The upper and lower circulation units can be flexibly equipped according to user needs. Can also be selected according to need.
2, for dehydrated vegetables, generally use three sets of equipment used in tandem to form the initial dry section, the middle section and the final dry section. In the primary dry section, due to the high moisture content of the material and poor air permeability, a small thickness of the material is used, a faster operating speed and a higher drying temperature. For materials whose material temperature is not allowed to exceed 60°C, in the initial dry section, the temperature of the drying gas can be as high as 120°C or less, and the residence time of the material in the final dry section is 3-6 times that of the initial dry section. The thickness of the material is the initial dry section. 2-4 times. For the requirement that the material temperature does not exceed 60°C, a dry gas at about 80°C may be used. The use of multi-stage combination enables better performance of the belt dryer and more uniform drying.
Engineering advantages: It can be specially designed for different characteristics of drying materials. The drying time is short, energy consumption is low, and the quality is good. It meets the requirements of national food hygiene and brings new opportunities for the industrialization of agricultural and sideline products.
