Embodiment 1

[0023] Referring to Fig. 1~4, the full-automatic low-temperature continuous vacuum drying equipment of the present invention comprises vacuum system (1), heating, cooling system (2), feeding material distribution system (3), material delivery system (4), unloading system ( 5), automatic cleaning system (6) and automatic control system (7). The vacuum system (1) has a Roots water ring vacuum unit (1-1) and a condenser (1-3) connected to the vacuum cavity (1-2). The vacuum cavity has an insulating layer, and the vacuum unit ( 1-1) and the condenser (1-3) are connected with a vacuum buffer tank (1-4) and a condensate collection tank (1-5), and the water vapor or organic solvent vapor in the drying process passes through the condenser (1- 3) After condensation, enter the condensate collection tank (1-5). The heating and cooling system (2) has three heating zones (2-1, 2-2, 2-3) and one cooling zone (2-4). The temperature of the hot water medium in the heating zone can be adjusted...

Embodiment 2

[0030] Referring to Fig. 1-4, the production method of the porous and loose traditional Chinese medicine extract dry matter of the present invention is to apply the extract material (3-1) evenly on the conveyor belt (4-1) under vacuum conditions, and carry out Low temperature continuous drying. The extract material (3-1) is preheated in the feed tank (3-2), and the feed temperature is controlled at 30-60°C. When the vacuum chamber (1-2) reaches the set vacuum degree (generally 400pa), the extract material is evenly coated on the conveyor belt (4-1) by the screw feed pump (3-3) at a feed rate of 1 to 10kg / h through the distributor (3-4) , the conveyor belt runs at a speed of 3-24m / h, moves through each heating zone (2-1, 2-2, 2-3) in turn, and finally passes through the cooling zone (2-4). In a vacuum environment, the extract material evaporates rapidly after absorbing heat, and water vapor or organic solvent vapor enters the condensate collection tank (1-5) after being conden...

Embodiment 3

[0032] Referring to Fig. 1-4, the production method and the equipment of the porous and loose traditional Chinese medicine extract dry matter of the present invention, the operating process is as follows: open the automatic control system (7) of the full-automatic low-temperature continuous vacuum drying equipment, complete the feeding tank temperature, heating Zone temperature, cooling zone temperature, condenser cooling medium temperature, feed speed, conveyor belt speed, fabric distribution angle and other process parameters setting, when the feed tank temperature, heating zone temperature, cooling zone temperature reach the set value, The vacuum system (1) starts to start, and when the vacuum degree of the vacuum chamber (1-2) reaches 400pa, start the feed distribution system (3) and the material conveying system (4), and evenly coat the extract material on the conveying On the belt (4-1), the extract material passes through three sections of heating zones (2-1, 2-2, 2-3) a...

Abstract

The invention relates to a method for producing porous loose traditional medicine concrete dry matter, and relative device. Wherein, it comprises vacuum system, heater, cooler, material feeding distributor, material transmitter, discharge system, automatic washing system, and automatic control system. Said concrete matter is preheated in feeding pot, via preset feeding speed and distributor to be coated on the transmission band; in vacuum, transmitting it via heating area and cooling area to obtain porous loose pan dry matter; removing it from the transmission band, to be cut by cutter into broker; and discharging via discharger. The invention processes low-temperature continuous dry in vacuum, to improve the producing ability, while the dry process is warm and quick, and the operation condition can meet GMP demand. The product has shadow color, better dissolving ability. And the invention has automatic control, to reduce labor density and improve working efficiency.

Description

technical field [0001] The invention relates to a method and equipment for producing porous and loose dried Chinese medicine extract. The dried product obtained by the method has the characteristics of light color, porous and loose, and good solubility, and is especially suitable for traditional Chinese medicines with high viscosity, thermoplasticity and heat sensitivity. The extract material belongs to the technical field of traditional Chinese medicine pharmaceutical industry. Background technique [0002] Drying of traditional Chinese medicine extract is an essential process in the production process of traditional Chinese medicine preparations. At present, the drying methods of traditional Chinese medicine extract mainly include vacuum oven drying, vacuum freeze drying and spray drying. There are certain defects and limitations in these drying methods. Vacuum oven drying cannot be operated continuously, the drying time is long, the production capacity is small, and the ...
