It is precisely because we can't lack these foods in our lives, so humans are going farther and farther in the drying research. The drying method is also constantly changing.
Sun drying and natural drying are the most primitive and oldest drying methods. The biggest advantage of this approach is that there is no extra consumption of resources, no cost. However, the shortcomings are also obvious: when the weather is not good, the weather is bad, or the wind is dry, the drying cannot be performed normally.
Then, folks invented the method of sulfur drying. For example, Hunan is rich in daylily. The newly picked day lily contains colchicine which is oxidized to dipiclosine after it enters the human body and can be toxic and cannot be consumed directly. Therefore, drying is a process that must be experienced. Local farmers use sulfur for “chemical dryingâ€. This method is indeed not subject to the weather, but sulfur is inadvertently easy to exceed the standard, it may damage health.
After entering the industrial age, electric boiler drying began to appear. This device can convert electrical energy into heat and use heat to dry the ingredients. The efficiency is high and the degree of automation is also greatly improved. However, the energy consumption of electric boilers is always a big problem. Everyone has studied physics. The law of conservation of energy in physics shows how much energy is consumed to generate much heat. Therefore, the use of electric boilers to complete a complete drying process, the electricity costs are not small.
Maybe it was because I experienced a variety of drying methods and experienced various deficiencies. A new generation of drying equipment - air heat pump began to appear in the market. Its appearance has allowed the drying to become intelligent, energy-saving and environmentally friendly, and has revolutionized drying.
As an example, the Niutet Air Energy Dryer, which is the most widely used in the drying industry, is exemplified. Niu Entai air energy dryer, set dehumidification, heating and drying, cold air drying in one, to meet the drying needs of a variety of ingredients, herbs. Users can set drying time, ambient temperature, humidity and other parameters through the control panel, precisely regulate the drying process variables, make the drying operation easier, and also improve the quality of drying ingredients.
However, the reason why the air heat pump has risen in the drying market is more important than its excellent energy consumption control. Because the heat pump absorbs heat from the air, the heating efficiency is higher than that of the electric boiler. Under ideal conditions, the heating efficiency of the air-energy heat pump can reach 400%, which is 4 times that of the electric boiler and equivalent to 75% of the electric boiler. In the long term, the longer the equipment is used, the more effective it will be. The gap in energy consumption between air energy dryers and electric boilers will further widen.
In the first half of this year, the country introduced relevant policies to inject large sums of money into agriculture. As an important equipment for agricultural drying, air-energy heat pumps have also received economic support. With industry demand and policy support, air energy dryers will continue to dominate the drying market for a long time and become a representative product for modern drying.
Pearlescent pigments are a diverse range of products that are composed of multiple layers of metal oxides applied to various substrates such as natural and synthetic mica, as well as borosilicates. By manipulating the composition of these thin metal oxide layers, a variety of captivating pearlescent effects can be achieved. When compared to other types of pigments, pearlescent pigments offer an unmatched ability to produce a unique, soft pearl-like luster. These pigments possess a distinctive surface structure, a high refractive index, and excellent transparency, allowing them to create the same stunning effect as natural pearl luster when used in transparent mediums.
Our Pearlescent Pigments category includes the following products:
