Description
Technical field
The present invention relates to acesulfame potassium production technology field more particularly to a kind of methods dried to aqueous acesulfame potassium.
Background technology
Acesulfame potassium, chemical name acesulfame potassium, is commonly called as 3,4-Dihydro-6-methyl-1,2,3-oxathiazin-4-one 2,2-dioxide potassium salt, is artificial synthesized forth generation sweetener, and sugariness is about sugarcane
130 times of sugar.It has the characteristics that in good taste, empty calory, and is not metabolized, does not put aside in vivo, stable in physicochemical property, answers extensively
For food, beverage, medicine, cosmetics and daily necessities etc..
In actual production, the acesulfame potassium after synthesis contains compared with juicy, is then needed in the production technology of rear workshop section
Take drying and processing.The hot-air after heating and filtering is sent into as shown in Figure 1, steam is usually used in the mode of drying acesulfame potassium
In vibrated fluidized bed, the throwing along the horizontal plane due to effect of vibration in vibrated fluidized bed of acesulfame potassium wet finished product is continuous forward to transport
It is dynamic.The hot-air of feeding passes through fluid bed, carries out heat exchange with wet finished product, the wet finished product of acesulfame potassium is dried.After heat exchange
Humid air is discharged by deduster by exhaust outlet, and the acesulfame potassium after drying, which enters in cooling bed, to cool down, and finally obtains peace match
Sweet finished product.
But thermal loss is big during the drying process, simultaneously because the air after heating is only inside vibrated fluidized bed
Plane flows, so the moisture on acesulfame potassium wet finished product crystalline particle surface can only be dried, and its intramolecular moisture can not be gone
It removes, leading to acesulfame potassium finished product, agglomeration problems are serious during storage, subsequent processing difficulty is big, it is necessary to use the side of artificial physics
Method is crushed.In conclusion a kind of drying mode ten that can have not only reduced energy loss but also product quality can be improved of selection
Divide necessity.
Invention content
The purpose of the present invention is exactly insufficient present in existing acesulfame potassium drying technology in order to solve, and provides a kind of utilization
The method of microwave drying acesulfame potassium can remove moisture and its intramolecular crystallization on acesulfame potassium wet finished product surface simultaneously
Water not only reduces energy consumption, and solves the caking phenomenon occurred due to crystallization water precipitation in storage.
To achieve the goals above, present invention employs following technical solutions：
A method of utilizing microwave drying acesulfame potassium, it is characterised in that：In acesulfame potassiumWet finished product feed binWith cooling bed it
Between a microwave dryer is set, acesulfame potassium wet finished product is delivered in the furnace chamber of microwave dryer, using discharging frequency in furnace chamber
Acesulfame potassium wet finished product is thermally dried for the microwave of 300MHz ~ 300GHz, temperature is controlled at 120 ~ 160 DEG C, after being oven-dried
Acesulfame potassium enter in cooling bed and cool down, finally obtain acesulfame potassium finished product.
During microwave drying acesulfame potassium wet finished product, the crystallization water of acesulfame potassium wet finished product evaporation is sent to by condenser
In condensate draining, recycle.
It is dry by using microwave in order to improve utilization efficiency of heat energy when drying acesulfame potassium in technical scheme of the present invention
Dry machine is thermally dried acesulfame potassium wet finished product, instead of originally by the hot-air feeding vibratory liquefaction after steam heating and filtering
The furnace drying method that heat exchange is carried out in bed, shortens energy transmission link, reduces thermal loss, reduce energy consumption.
Using the penetrability and high-frequency of microwave, hydrone is made to do high-speed wheel pendular motion in its magnetic field, between hydrone
Rubs mutually generates great heat, to make the crystallization water quickly be precipitated from inside to outside, and most effectively retains the energy of conversion.
The invention not only eliminates the moisture content on acesulfame potassium wet finished product surface using micro-wave drying method, and significantly reduces acesulfame potassium point
Crystal water content inside son.Acesulfame potassium finished product energy long-time storage after microwave drying, and it is prevented from caking, it ensure that product
Quality.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the former process flow chart for drying acesulfame potassium；
Fig. 2 is the modified technique flow chart using microwave drying acesulfame potassium.
Specific implementation mode
As shown in fig.2, a kind of method using microwave drying acesulfame potassium, is included in wet finished product feed bin and cooling bed
Between be arranged a microwave dryer, in order to achieve the purpose that dry acesulfame potassium, following steps can be taken：
Microwave dryer is opened, while acesulfame potassium wet finished product is sent out from wet finished product feed bin by batcher, is sent using conveyer belt
Enter in the furnace chamber of microwave dryer.The microwave that release frequency is 300MHz ~ 300GHz in furnace chamber adds acesulfame potassium wet finished product
Heated drying, temperature are controlled at 120 ~ 160 DEG C.By adjust microwave dryer conveyer belt electric machine frequency, control acesulfame potassium it is wet at
Residence time of the product in furnace chamber, to ensure that acesulfame potassium drying is abundant.Acesulfame potassium material quilt after microwave dryer is dried
It is sent into cooling bed, cooling processing is carried out to acesulfame potassium material using filtered cold air in cooling bed, finally
Acesulfame potassium finished product is obtained after cooling, is collected in finished product bin.
In microwave dryer, acesulfame potassium wet finished product can evaporate the crystallization water when passing through microwave drying, the knot of these evaporations
Brilliant water is recovered to condensate draining by condenser, is recycled for production.
In cooling bed, the cold air that cools down to acesulfame potassium material is after heat exchange by deduster by air-introduced machine
Discharge.
The heat that new process changes traditional handicraft transmits heating mode, is heated using novel microwave, substantially increases energy profit
It is not lumpd with the acesulfame potassium of rate, drying, reduces the conversion usage amount of steam, through measuring and calculating, our company can save steam 1.6 ten thousand every year
Ton.
