Description
Technical field
The present invention relates to a kind of drying means of watertight ball.
Background technology
At present, the watertight ball in pharmaceutical factory generally adopts oven drying, perhaps microwave drying, and there is following shortcoming in drying means: the time is long, and baking temperature is high, causes energy consumption too high; It is too high that while part medicine can local temperature occur, causes the pill surface phenomenon dry and cracked, that burn to occur.
It is 201220174418.0 that the applicant has submitted application number on April 24th, 2012 to State Intellectual Property Office, and denomination of invention is the Chinese utility application of " a kind of dry microwave fluid unit of solid particle that is used for ".This application discloses a kind of dry microwave fluid unit of solid particle that is used for, and comprises microwave drier, fluidized bed plant, air-blowing device and real time monitoring apparatus, and said fluidized bed plant is connected with the air-blowing device; Fluidized bed plant is located in the cavity of microwave drier, and real time monitoring apparatus is electrically connected with microwave drier and air-blowing device respectively; Said fluidized bed plant comprises fluid bed and gas distribution grid.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide simple to operate, energy consumption is little, weak point consuming time, and baking temperature is low, can avoid the drying means of the watertight ball that the pill surface burns.
Goal of the invention of the present invention is realized by following technical scheme:
A kind of drying means of watertight ball uses the microwave fluid bed that the watertight ball is carried out drying first.
In above-mentioned drying means, said baking temperature is preferably 50 ℃-80 ℃, and wind speed is preferably 0-30m/s.
In above-mentioned drying means, the diameter of said watertight ball is at 2mm-8mm, and initial water content is 12% ~ 25%.When the water content of watertight ball stops during for 4%-9% dryly, the watertight ball is taken off from the microwave fluid bed, obtain dried product.
In above-mentioned drying means, as preferably, said microwave fluid bed comprises microwave drier, fluidized bed plant, air-blowing device and real time monitoring apparatus, and said fluidized bed plant is connected with the air-blowing device; Fluidized bed plant is located in the cavity of microwave drier, and real time monitoring apparatus is electrically connected with microwave drier and air-blowing device respectively; Said fluidized bed plant comprises fluid bed and gas distribution grid.
Compared with prior art, the present invention has following beneficial effect:
Drying means provided by the invention, simple to operate, energy consumption is little, weak point consuming time, baking temperature is low, the phenomenon that can avoid the pill surface to burn.
Description of drawings
Fig. 1 is a microwave fluid unit structural representation of the present invention.
Fig. 2 is the hierarchy in the fluid bed of the present invention.
The specific embodiment
As depicted in figs. 1 and 2, a kind of dry microwave fluid unit of solid particle that is used for comprises microwave drier 1, fluidized bed plant 2, air-blowing device 3 and real time monitoring apparatus 4, and said fluidized bed plant 2 is connected with air-blowing device 3; Fluidized bed plant 2 is located in the cavity of microwave drier 1, and real time monitoring apparatus 4 is electrically connected with microwave drier 1 and air-blowing device 3 respectively; Said fluidized bed plant 2 comprises fluid bed 21 and gas distribution grid 22.The panel of microwave drier 1 is provided with touch-screen 11.Air-blowing device 3 comprises air blast 31, relief valve 32, valve 33, airspeedometer 34.Be provided with some in the fluid bed 21 at a distance from dish 24.Real time monitoring apparatus 4 comprises camera and computer.The top of microwave drier 1 and side all are equipped with the far infrared temperature probe.Said gas distribution grid 22 is provided with 35-42 purpose micropore.Two magnetrons are equipped with in corresponding position, the left and right sides in the cavity of said microwave drier 1.The microwave power of microwave drier 1 is a stepless regulating, and power regulating range is 0 ~ 2000W.The stainless steel orifice plate that 23 places of distribution grid up and down of fluid bed 21 all have area to equate.
With the watertight ball is dry object, changes microwave power, wind speed, pill quality, and the control cavity temperature is lower than 70
oC investigates the influence of microwave fluid bed to the pill rate of drying.
