Drying, as an essential process in the processing and manufacturing of many industries and agricultural products, will greatly affect the final quality of the product. Among them, due to its own particularity, the drying requirements of Chinese herbal medicine are much harsher than ordinary products.
The drying of Chinese medicinal materials should pay attention to "heating". Different varieties of medicinal materials, the drying process is also different. Some Chinese medicines will lose their efficacy at a certain temperature, so it is very important to control the temperature during the drying process. In addition, some Chinese herbs should not be dehydrated too quickly, otherwise it will affect the efficacy.
Before, the dehydration of Chinese herbal medicine mainly relied on "sunshine", but with the development of science and technology, a variety of drying equipment has emerged, Chinese herbal medicine has also bid farewell to the era of "watching the day to eat", and achieved industrial development. But among the dizzying array of drying equipment, how do you choose?
The difference between different drying systems is that different heat sources are used to heat and dry, currently common coal, natural gas as well as electrical, solar and air energy.
In the past few years, medicinal materials have used coal-fired boilers to dry more, but in the wave of "coal to electricity", coal-fired boilers have become the object of elimination. The use of natural gas, the cost is relatively high, can not guarantee the supply; Direct use of electricity is also expensive; The use of solar energy is also unstable, if the weather is cloudy and rainy, and can not complete the drying, production will be affected will produce losses.
In recent years, the appearance of air-energy heat pump drying bar has injected new vitality into the drying of Chinese herbal medicine. The advantages of the equipment make it possible to complete high-quality drying.
Chinese medicine dryer is a kind of equipment suitable for drying various Chinese medicinal materials; Parallel wind and vertical wind design, temperature adjustable range of 5℃ ~ 75℃, respectively, low temperature, moderate and high temperature Chinese medicine dryer. Suitable for various shapes of medicinal materials drying.
The structure of the drying system includes:
1. Insulated drying box
2. Hot air circulation system
3. Dehumidify the system
4. Automatically heat the host
5.Automatic temperature and humidity control system
So, what are the advantages of air energy heat pump drying equipment?
Five advantages of heat pump drying equipment
1, constant temperature drying, uniform heating inside and outside the material to ensure thorough drying, appearance is not damaged, material activity and original material color and nutrition are preserved to a greater extent;
2. Different drying temperatures can be set to meet the drying needs of medicinal materials;
3. High security. No harmful gases are produced, and there is no danger of inflammability and explosion;
4, automatic operation, no need to rely on manual operation to change the position of the refuelling vehicle, flipping, etc., higher drying efficiency;
5. Reduce costs. During the operation of the equipment, the evaporator absorbs the heat of the outside air, and can recover the waste heat of the exhaust gas in the drying room, and the compressor works to transfer the energy to the drying box, and the cycle is repeated to achieve the purpose of drying.
In terms of heating efficiency, the air energy heat pump dryer reaches 1 KWH of electricity, which can transfer the heat equivalent to 4 KWH of electricity in the drying room, and the working cost is far lower than other drying methods.
The emergence of air source heat pump dryers has subverted the traditional drug drying method.
Air energy heat pump dryer is widely used in ginseng, ganoderma lucidum, polygonum multiflorum, wolfberry, angelica, lily, purple, bergamot, gastrodia, yam, chrysanthemum and other Chinese herbs drying.
