Professional Microwave Vaccum Drying Equipment For Herb / Food

microwave vacuum dryer machine for herbs, food

The microwave vacuum dryer equipment is a new technology for drying materials under vacuum in a vacuum state.
The microwave vacuum drying speed is fast and efficient, and the low temperature state is dry and oxygen-treated, and has the remarkable features of energy saving and high efficiency.
It can realize multi-purpose and multi-species materials processing under the conditions of negative pressure and low temperature oxygen barrier.
The transmission structure of the horizontal microwave vacuum device is a novel planetary sprocket actuator that keeps the material in a horizontal state.
This design method can maintain a large contact area between microwave energy and materials, and has more uniform drying efficiency. It is a unique design method for Boda microwave continuous innovation.

Applicable material
The microwave vacuum dryer equipment can be applied to the fields of traditional Chinese medicine, western medicine, chemical industry, food, etc.
Applicable materials include: traditional Chinese medicine extracts, pharmaceutical intermediates, Chinese and Western medicines, chemical anaerobic reactions, health care products with heat-sensitive ingredients and new product development of various laboratories.

With high drying yield, good quality and low processing cost, microwave vacuum drying equipment is a high-tech product integrating electronics, vacuum, mechanics, thermodynamics, program control and other disciplines. Based on the in-depth study of physical changes in matter, internal and external heat and mass exchange, and water migration under vacuum conditions, a new technology and process have been developed.
In industrial large-scale production, there are many items that cannot be dried under high temperature conditions, such as some medicines, chemicals, nutritious foods, and high-grade Chinese herbal medicines such as ginseng and velvet antler, especially for the drying of traditional Chinese medicine extracts. High efficiency features, in order to ensure product quality,
Microwave heating is an electromagnetic wave heating. The microwave directly acts on the material to be heated at the same time inside and outside. It does not need to transfer heat through convection or conduction, so the heating speed is fast, the drying efficiency is high, and the temperature control is easy.

Characteristics
1. Efficient, conventional vacuum drying equipment is heated by steam. It needs to be heated from the inside to the outside. The heating speed is slow and it takes a lot of coal. The microwave vacuum drying equipment uses electromagnetic wave heating, no heat transfer medium, direct heating. Inside the object, the heating rate is fast, and the 1 kW microwave can heat the water at normal temperature to 100 ° C in 3-5 minutes, which avoids the above disadvantages, so the speed is fast, the efficiency is high, the drying cycle is greatly shortened, and the energy consumption is reduced. Compared with conventional drying technology, it can increase the work efficiency by more than four times.
2, heating evenly, due to microwave heating, the material is heated simultaneously from the inside to the outside, the temperature difference between the inside and outside of the material is very small, does not produce the situation of internal and external heating inconsistent in the conventional heating, resulting in the effect of puffing, which is conducive to crushing, The drying quality is greatly improved.
3, easy to control, easy to continuous production and automation, due to the rapid adjustment of microwave power and inertia, easy to control, you can adjust the temperature between 40 °C -100 °C.
4, small size, easy installation and maintenance
5, the product quality is good, compared with the conventional method, the quality of the processed products has been greatly improved.
6, microwave has the effect of disinfection, sterilization, product safety and hygiene. The shelf life is long.
7. The economic benefits are significant.

2, Design consideration:

dehydrate water 1kg for 1kw/h microwave drying

3, Application:

1), material shape:multiple

2), Drying temperature:40~60℃ (vacuum low temperature fast drying)

4, Microwave drying process:

Raw material ——tray loading——feeding——microwave drying and dehumidification——timing ——discharge——finished production

5. System composition:

Microwave heating tank, microwave generator, vacuum pump, circulating air pump, cold water dehumidification system, material tray, turntable frame, temperature, pressure detection and PLC control system.

6. Descriptions:

1), The main technical performance, overall structural design and related control of the machine have international and domestic leading level. The equipment is designed and manufactured integrative, it is easy use just connecting the power source.

2), The overall structure of the whole machine is smooth, beautiful, practical and small area.

3), The microwave generator is the core of the device. In order to achieve its high performance and high reliability, we use all the first class electronic devices to achieve work continuously for 24 hours.

4), Adopts the most advanced multi-port feeding mode, microwave electromagnetic field from the top to the bottom of the broadband feed, accurate network analysis design can make the material directly accept the electromagnetic field energy, so the loss is smaller than the reactive power fed from the side or other ways at domestic and abroad. the heating efficiency is increased by more than 10%, and the uniformity of material heating is 2-3 times higher.
