Hot air microwave fluidized drying device for drying traditional Chinese medicinal materials

Abstract

The invention belongs to the technical field of drying equipment and particularly relates to a hot air microwave fluidized drying device for drying traditional Chinese medicinal materials. The hot airmicrowave fluidized drying device for drying the traditional Chinese medicinal materials is mainly composed of a vibration fluidization device, an electric heating tube (4), a material disc (7), a microwave drying chamber (8), at least six magnetic control microwave tubes (10), an induced draft fan (11) and a control system. The hot air microwave fluidized drying device for drying the traditionalChinese medicinal materials is characterized in that the microwave drying chamber (8) is of a multi-mode box-type structure, and the magnetic control microwave tubes (10) are arranged on the top of the microwave drying chamber (8) and connected with the microwave drying chamber (8) through independent microwave feed-in waveguides. The vibration fluidization device is composed of a damping spring(1), a vibrator motor (2) and a vibration rack (3), wherein the vibration motor (2) drives the vibration rack (3) and the material disc (7) to vibrate, and the vibration rack (3) is further connectedwith a rack of the hot air microwave fluidized drying device through the damping spring (1). The hot air microwave fluidized drying device for drying the traditional Chinese medicinal materials is simple in structure and high in practicability, and the heat energy and microwave energy absorbed by the materials are more uniform.

Description

technical field [0001] The invention belongs to the technical field of drying equipment, and in particular relates to a hot-air microwave fluidized drying device for drying Chinese medicinal materials. Background technique [0002] Drying is an important step in agricultural production and a key link in agricultural production. It is an important part of realizing the mechanization of grain production, and drying is an economical and effective method for long-term preservation of many agricultural materials and foods. Drying mechanization technology uses machinery as the main means, adopts corresponding processes and technical measures, artificially controls factors such as temperature and humidity, and reduces the moisture content in crops without damaging the quality of crops to make them meet the national safety storage standards. drying technique.

Problems solved by technology

[0003] Although the traditional atmospheric pressure hot air drying is simple and low in cost, it has a serious impact on the quality of the product (such as surface hardening, solute loss, etc.), especially for drying agricultural products, food and biological products

Vacuum drying and air freeze drying can obtain high-quality products, but in vacuum drying, because the pressure is kept at a certain level, it is easy to form a balance of water vapor partial pressure inside and outside the material, which limits the improvement of drying rate
