Advantages and disadvantages of traditional fireworks drying equipment

Advantages For example, the characteristics of high-temperature heat pump (drying) technology:

1. Save energy

Energy saving is the starting point and main advantage of the initial application of high temperature heat pump. The efficiency of traditional dryer is only 3% ~ 5%, but the drying efficiency of heat pump will be obviously improved, saving about 50% energy compared with traditional heat pump drying unit. Moreover, the traditional dryer has high running cost, limited by the geographical and project use characteristics, and its application scope is not wide. Gan Yong air source high temperature heat pump technology has made some breakthroughs in this respect, mainly including:

A. Low operating cost: the operating cost of high-temperature heat pump is equivalent to that of coal burning; About 40% lower than fuel/gas cost; Energy saving 50% compared with pure electric energy-consuming equipment.

B. Safe and reliable: without any electric heating device, water and electricity are completely separated, which fundamentally eliminates the occurrence of leakage accidents caused by ordinary electric heating, and will not cause dangers such as lack of oxygen, poisoning and explosion when used in a closed space like a gas hot water heating system.

C. Comfortable and convenient: it is not affected by bad weather such as rain and snow, and enjoys constant temperature hot water for 24 hours. It can also work normally in the environment of MINUS 5℃-40℃.

D. High stability: The first requirement of industrial high-temperature heat pump is reliable quality and stable operation! In order to meet the requirements of continuous production of customers. Therefore, Gan Yong high-temperature heat pump has been precisely designed and strictly controlled in the control and protection of important parameters such as compressor discharge pressure, discharge temperature, overcurrent, overheating and overload. So as to ensure that the heat pump system runs under stable and reliable safe working conditions.

E. environmental protection: special high-temperature refrigerant is adopted, which has no pollution to the environment. The application of heat pump drying technology in vegetable dehydration can save energy by 90%.

2. The quality of dried products is good.

Heat pump drying is a mild drying method, which is close to natural drying. The evaporation rate of surface moisture is close to the migration rate of internal moisture to the surface, which makes the dry goods have good quality, good color and high product grade. The aromatic volatile substances, vitamins with poor heat resistance and large color change obtained by ordinary drying methods are less retained. For example, the retention rate of gingerol in ginger obtained by drum dryer is only 20%, while that obtained by heat pump drying is as high as 26%. Van Blarcom and Mason's experiments show that even at 50℃, macadamia nuts dried by heat pump will not appear the above browning phenomenon, and the original color, flavor and nutritional components of nuts can be well maintained.

3. The drying parameters are easy to control and the adjustable range is wide.

In the process of heat pump drying, the temperature, humidity and circulating flow of circulating air can be accurately and effectively controlled, and the temperature adjustment range is from normal temperature to 100℃ (with auxiliary heating device), and the relative humidity adjustment range is 15% ~ 80%, which is suitable for drying heat-sensitive materials.

4. Environmentally friendly

Material drying requires not only improving product quality and saving energy, but also environmental protection. Based on the same evaluation criteria, the impact of heat pump on global warming is very small compared with CO2 released by electricity. Environmental protection is the advantage of heat pump drying. At present, foreign countries advocate the application of heat pump to reduce CO2 emissions, and it will be further applied. The disadvantage is, of course, spending money.
