Batch Type Microwave Drying Machine For Medicinal Liquid

Batch Type Microwave Drying Machine For Medicinal Liquid / Industrial Steam

Compared with the traditional dryer, the microwave vacuum drying equipment greatly increases the drying efficiency and greatly reduces the power consumption of drying. However, the discharge of water vapor under vacuum is a difficult problem to be solved by the microwave vacuum dryer. . Since the existing microwave vacuum drying equipment is generally only used for processing articles with less water content such as leather and medicine, there is still no reliable, efficient and energy-saving way to complete the cavity of the microwave vacuum dryer. The drying of water vapor concentration, the current application of vacuum drying equipment in industrial and pharmaceutical water vapor treatment generally has the following schemes:

1. The water vapor is directly pumped out of the closed container by a common rotary vane vacuum pump. If the water to be dried has a large water content, a large amount of water enters the vacuum pump, which causes the water vapor to condense in the air pump, and on the other hand, excessive water vapor will Short pump life and high cost.

2. By using a water ring vacuum unit, the Roots pump is used as the main pump and the water ring pump is used as the front stage pump in series. It can be used to remove a large amount of condensable steam. However, the unit is inefficient, generally around 30%, preferably up to 50%. The degree of vacuum is low, not only because of structural limitations, but more importantly by the saturated vapor pressure of the working fluid. Water is used as the working fluid, and the ultimate pressure can only reach 2000Pa-4000Pa.

3. There is a scheme for using a gas-liquid separator between the vacuum pump and the drying chamber. The gas-liquid separator utilizes different gas-liquid specific gravity. In a vessel that suddenly expands the outlet, after the flow velocity is reduced, during the fluid turning process, fine droplets in the gas phase sink and separate from the gas, or use a cyclone in the gas phase. The fine droplets are smashed into the wall by the inlet high-speed airflow, and the kinetic energy is lost after the collision and is separated from the steering gas. However, the water vapor separation efficiency is low, the equipment is bulky, the equipment structure is complex, and the space is occupied, which is not conducive to product promotion.

he microwave technology of industrial microwave heating dryer has been widely used in heating and drying, covering heating and drying of food, heating and drying of industrial products, dehydration and drying of agricultural and sideline products, pre-baking and sintering of ceramic industry, oil refining, etc. . Because of the good penetrability of the microwave dryer, the energy can be converted into heat energy into the deep layer of the material, and the surface and the inner lining are uniformly heated, so that the deep water of the material evaporates rapidly, forming a high internal steam pressure bar, forcing the material to puff.

In the process of controlling microwave heating in industrial microwave heating dryer, we need to heat the material to the boiling temperature of moisture, which is suitable for substances that are not sensitive to temperature changes. In order to adapt to the food baking process, the temperature of the material must be quickly reached. Allow to heat within the upper temperature limit.

Industrial microwave heating dryers are good at maintaining the quality and flavor of food. At the same time, as a biological effect energy, industrial microwave heating dryer can kill E. coli, Bacillus and mold in a short time.

Generally, heating and drying, the key is to control the heating temperature, and the purpose can be achieved by adjusting the microwave power and the transmission speed. Microwave heating must take into account the shape and domain properties of the medium. For the processing of wood, attention should be paid to the loose structure of pine and fir. The water is easy to migrate when heated. The hardwood structure such as eucalyptus and oak is difficult to migrate. It is necessary to pay attention to the heating speed to prevent the heating from causing bursting, deformation and prevention. Internal scorching does not occur internally.

3.Batch Type Microwave Drying Machine For Medicinal Liquid Technical Parameters:

efficient

Short time and fast speed. Microwave heating is a process in which the object to be heated becomes a heating element, and heat conduction is not required. The microwave penetrates the material from all directions to achieve uniform heating in a short time, which greatly shortens the time.

Uniform heating

In order to increase the drying speed by the conventional drying method, it is necessary to raise the external temperature, so that it is easy to produce a hard shell outside the pellet. Microwave heating is simultaneous heating inside and outside, does not require heat conduction, and generally uniformly penetrates electromagnetic waves to generate heat, so the uniformity is greatly improved.

Low temperature sterilization

Low temperature sterilization maintains medicinal ingredients. Generally, the sterilization temperature can reach the effect at 70-80 °C, and the sterilization effect of various materials is generally within 3-5 minutes. Therefore, the intrinsic quality of the processed Chinese herbal medicine and the color, taste and efficacy of the Chinese herbal medicine are not greatly affected.

Energy efficient

Conventional thermal sterilization often has heat loss in the environment and equipment, and the microwave directly treats the material, so there is no additional heat loss, so the working environment of the worker is good, and the electricity can be saved by 30% compared with the far infrared heating.

Advanced technology

Easy to control and advanced technology. Compared with the conventional method, the device can be used immediately, without thermal inertia, and the operation is flexible and convenient. The microwave power is adjustable and the transmission speed is also adjustable.
