Vermicelli is a kind of dry noodles made by adding salt, alkali and water to wheat flour and then cut into a certain length. It is one of the most popular pasta. With the development of diversified market, the common development pattern of staple food type, flavor type, nutrition type and health care type has been formed. Drying is a main procedure in the production process of dried noodles. The drying method not only affects the quality of dried noodles, but also affects the drying efficiency. How to ensure the quality of drying and reduce the drying cost is a required course for the noodle enterprises to participate in the fierce market competition.
There are many methods and advantages in drying vermicelli from the principle of natural air drying to the use of various drying equipment. For example, although the natural air drying has good effect and low cost, it has to rely on the weather. The sun is not available every day, and it needs to be placed in the indoor sunshine, so it is inevitably polluted by dust. Other drying methods, such as electric heating, have high energy consumption and high cost although they are fast. Throughout all kinds of drying process, it is the use of hot air to absorb the moisture on the dried noodles to achieve the purpose of drying. Hot air is both a heat carrier and a wet carrier. When the humidity in the hot air reaches saturation, the effect of dehumidification will become worse and worse, and the moisture absorption efficiency will gradually decline. Therefore, people have been looking for more energy-saving and effective drying methods, and with the popularity of dehumidifiers , let drying dehumidifier into more dried noodles production enterprises, in the development of noodle industry.
Drying principle of dehumidifier dried noodles: use dehumidifier to suck the wet air in the indoor air into the machine, extract the moisture in the wet air and discharge it out of the room through the work of the compressor, at the same time, under the action of the fan, the processed dry air is sent back to the room, and the dried noodles are hygroscopic under the action of air convection, so as to achieve the drying effect of dried noodles.
The advantages of the dehumidifier are as follows:
1. It can be finished indoors and the drying effect is good. Drying with dehumidifier can be completed indoor, all-weather, not affected by the weather, at the same time, no need for other auxiliary raw materials, it belongs to pure natural air drying, with good drying effect, no crispness, no crispness, no acid, no moisture, no fracture, straight strip, bright and clean color.
2. The drying speed is uniform and the moisture absorption effect remains unchanged. Through the dehumidifier's work, the indoor air is always kept in the dry state. At the same time, under the action of the fan, the convection of the indoor air is accelerated, and no other auxiliary heat tools are needed, Therefore, the drying speed is uniform, which effectively ensures the quality of dried noodles. In addition, the moisture extracted from the dried hot air is continuously converted into liquid water by the dehumidifier and discharged outdoors. The relative humidity in the air can be controlled and kept in the dry state all the time. The moisture absorption effect will not decrease with the extension of working time
3. Simple installation and low cost. The dehumidifier is simple to install and easy to move. It can be directly installed indoors. At the same time, the dehumidifier uses the refrigeration principle for heat exchange. The heat in the air is recovered by using two devices (hydrophilic aluminum foil heat exchanger), so that the indoor temperature is not damaged. Only the compressor and fan need electricity, so it is more energy-saving and power-saving to use the dehumidifier to dry the dried noodles.
4. Effectively reduce the production cost of noodle enterprises and improve business efficiency. After a lot of practice, dehumidifier is an effective energy-saving drying method in many drying processes, which has been adopted by a large number of noodle enterprises. In addition to the above three advantages, it also has the characteristics of intelligent control, convenient management, low investment cost and simple maintenance.
