Pill microwave vacuum drying sterilization machine

Pills are traditional and commonly used traditional Chinese patent medicines and simple preparations, which have a long history, are easy to take, have a certain slow release effect, and have a lasting effect. During production, it is necessary to add some water or extract to make pills, and the pills made need to be dried.

Pills come in different sizes and have a certain degree of density. When dried, the central moisture is not easily discharged. If the drying temperature is too high, it seriously affects the effective ingredients of the pill and is not easy to disintegrate, directly affecting the efficacy of the pill. Microwave vacuum drying of pills is fast and fast, usually taking only 2-3 hours to obtain high-quality dried pills. Due to the low drying temperature, the pills are prone to disintegration.

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, and dry more than ten times faster. It has a good sterilization effect on pills while drying, without reducing environmental pollution, greatly improving the economic benefits of enterprises, and becoming an advanced modern drying technology.
