Abstract
The utility model discloses a high-efficient continuous drying device of modified, including an at least heater, its characterized in that still includes an at least vacuum apparatus, vacuum apparatus's evacuation mouth with commodity circulation latus rectum intercommunication in the heater makes the commodity circulation keeps certain vacuum state in dredging the meridian. The utility model has the advantages of: the production process continuity is strong, production efficiency is high, the material is heated for a short time, and the material is heated evenly, the product quality is uniform, the whole drying process is carried out under vacuum, the effective components in the material are well preserved, the equipment structure is compact, and the required installation space is small.
Description
Technical Field
The utility model relates to a material drying technology field, in particular to high-efficient continuous drying device of modified. It is mainly used in the fields of pharmacy, food and chemical industry, and is particularly suitable for the drying stage in the extraction and concentration process of the effective components of the traditional Chinese medicinal materials.
Background
In the fields of pharmacy, food and chemical industry, residual water or other moisture in the concentrated materials needs to be removed through a drying step.
In the existing stage of medicine production process, drying equipment which is widely applied in a drying section comprises a spray drying tower, a vacuum drying box, a vacuum crawler-type dryer and the like. These devices have a number of disadvantages, such as:
a spray drying tower: drying can be carried out only under normal pressure, the temperature during drying is high, and heat-sensitive substances in the medicine are easy to inactivate. The powder yield after drying is only 70%, and the waste is serious. The heat efficiency is low (generally 30-40%), and the steam or power consumption is large. The volume is bigger, takes up an area of more.
And (3) vacuum drying oven: the concentration of the concentrated solution is required to be higher, the continuity of industrial production is poor, only single batch drying is needed, the drying efficiency is low, and the drying time is over 10 hours generally. The effective components in the materials are easy to be damaged after long-time drying. The tray has a small amount of medicine, and once the amount of medicine exceeds the 1/3 height of the tray, the material is easy to spill out during drying, which causes waste.
Vacuum crawler-type desiccator: the equipment is large in size and long, and needs a huge floor area. The equipment barrel is of a multilayer crawler-type structure, so that batch replacement and cleaning are extremely difficult, and thorough cleaning is difficult.
At a given temperature, any wet material containing water (or other moisture, in the case of water, the same applies hereinafter) has a vapor pressure that vaporizes when the vapor pressure is greater than the partial pressure of water vapor in the surrounding gas. Along with the evaporation, the water content and the vapor pressure of the material are reduced, the partial pressure of water vapor in the surrounding gas in the pipeline is gradually increased, the evaporation rate is gradually slowed down, until the vapor pressure of the water vapor contained in the material is equal to the partial pressure of the water vapor in the gas, the system is balanced, and the evaporation is not continued.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that aim at solving traditional drying equipment's defect and provide a modified high-efficient continuous drying device, this high-efficient continuous drying device can adopt the evacuation mode to reduce the influence that steam partial pressure brought, improves dry efficiency, reduces and remains, reduces the installation space, keeps the continuity of production, shortens the time of being heated of material, realizes the low concentration feeding, obtains the even stable dry material of quality in succession.
The utility model discloses the technical problem that will solve can realize through following technical scheme:
an improved high-efficiency continuous drying device comprises at least one heater and is characterized by further comprising at least one vacuum device, wherein a vacuumizing port of the vacuum device is communicated with a logistics circulation path in the heater, so that the logistics circulation path is kept in a certain vacuum state.
In a preferred embodiment of the present invention, the heater is a heat exchanger.
Due to the adoption of the technical scheme, the dilute material enters the heater (the type of the heat exchanger is not limited herein) through the power device. The dilute material absorbs the heat released by the heating medium in the heater, and in the process that the material advances gradually into the heater, the moisture is gradually evaporated and gasified, along with the progress of evaporation, the water content and the steam pressure of the material gradually decrease, and the steam partial pressure of the surrounding environment gradually increases, so that the partial pressure difference decreases, and the evaporation rate is attenuated. The vacuum device is adopted to ensure that the circulation path of the material in the heater is vacuumized, and the water vapor partial pressure of the surrounding environment is reduced again, so that the attenuation of the evaporation rate is slowed down, and the smooth proceeding of the evaporation is ensured. And finally, a two-phase mixture of the dry material and the water vapor is obtained, the two-phase mixture enters a separator, the dry material falls downwards under the action of gravity, and saturated gas enters a condensation system along with the vacuum suction, so that the separation of the material and the steam is realized, and the required dry product is finally obtained.
The utility model discloses the higher heat medium of heater adoption temperature, for example: industrial steam, superheated water.
Compare in other drying equipment, the utility model has the advantages of down: the production process continuity is strong, production efficiency is high, the material is heated for a short time, and the material is heated evenly, the product quality is uniform, the whole drying process is carried out under vacuum, the effective components in the material are well preserved, the equipment structure is compact, and the required installation space is small.
Drawings
Fig. 1 is a schematic view of the improved efficient continuous drying device of the present invention.
Detailed Description
The invention is further described below with reference to the accompanying drawings and the detailed description.
Referring to fig. 1, there is shown an improved high efficiency continuous drying apparatus including at least one heater 10, which is a heat exchanger. The device also comprises at least one vacuum device 20, and a vacuum pumping port of the vacuum device 20 is communicated with a material flow circulation path in the heater 10, so that the material flow circulation maintains a certain vacuum state in the passage.
The dilute material absorbs the heat released by the heating medium in the heater 10 to finally obtain a two-phase mixture of the dry material and the water vapor, the two-phase mixture enters the separator 30, the dry material falls downwards in the separator 30 due to the action of gravity, and the saturated gas enters the condensing system 40 along with the vacuum suction, so that the separation of the material and the steam is realized, and the required dry product is finally obtained.
