Extract microwave vacuum dryer

The extraction of traditional Chinese medicine is an important link in the production of modern traditional Chinese medicine. The extraction methods include boiling, soaking, and infiltration. The temperatures include high, medium, and low temperatures. The extraction media usually include water, alcohol, etc. Due to the variety of traditional Chinese medicine, the extraction methods and the use of media are different, the extracts of traditional Chinese medicine - extracts - extracts are also very different. The extracts are the essence of traditional Chinese medicine, which are extracted from a large number of traditional Chinese medicines. It is hard won.

The extracted Chinese medicine extract is usually processed into granules, pills, capsules, tablets and other modern traditional Chinese patent medicines and simple preparations for easy use. However, because the extract is viscous and contains certain sugar, oil, saponins, etc., it is difficult to dry. The traditional drying method requires high temperature and long time, so the dried extract has a large loss of effective ingredients, which reduces the efficacy and fails to achieve the desired efficacy. Therefore, the drying of traditional Chinese medicine extracts has become a bottleneck in modern Chinese medicine production.

The WBZ series intelligent static microwave vacuum drying equipment is a comprehensive high-tech drying equipment that combines microwave energy application technology with vacuum drying technology. It solves the global problem of uniform drying of materials in a static state. The equipment has high safety and stability, and is a patented technology of our company. It has the characteristics of low drying temperature, high quality, short time, high efficiency, high yield, and low cost. It is a high-quality, fast low-temperature drying equipment.

The evaporation temperature of water during the drying process of materials is directly related to atmospheric pressure. The lower the atmospheric pressure, the lower the boiling point of water. At one atmosphere, the boiling temperature of water is 100 ℃. When the vacuum degree is less than -0.08MPA, the boiling point of water drops to 30-40 ℃. Therefore, in a vacuum state, materials can be quickly dried at lower temperatures.

Traditional heating is carried out through conduction, convection, and radiation. In a vacuum state, air convection is difficult to carry out. Only by providing thermal energy to the material through conduction can the surface of the dried paste material first dry and harden, forming a 'solid' shell. External heat is difficult to enter, and internal moisture is difficult to remove. Therefore, the drying speed is slow, the efficiency is low, the cycle is long, and the temperature is difficult to control, directly affecting the drying quality of the material.

Microwave vacuum drying is the process of heating materials using microwave energy in a vacuum state. In the microwave field, the material absorbs microwave energy and generates heat as a whole. The heating speed is fast, the thermal energy distribution is uniform, the thermal energy utilization rate is high, and the moisture is quickly discharged. At the same time, the transmission of microwave energy in a vacuum state is not affected, and the material can be quickly heated by the microwave without energy loss. The material does not form a hard shell during the drying process, and the gas during drying is easily discharged. The drying temperature is low, the speed is fast, and the quality is high. The effective ingredients of the medicine can be retained more.

Microwave vacuum drying is a method where the material is heated as a whole, and the drying process and quality are highly controllable. It changes the traditional method of calculating the drying amount based on the paving area and directly calculates the drying output of the equipment using the loading amount. Therefore, microwave vacuum drying equipment has completely changed traditional drying technology. It not only has low-temperature, fast, and uniform drying characteristics, but also has high controllability, which can greatly improve drying quality, save up to 80% energy, dry more than ten times faster, achieve almost 100% yield, reduce environmental pollution, greatly improve enterprise economic benefits, and become an advanced modern drying technology.
