Abstract
The present invention discloses a continuous drying mode for continuously drying potassium acetosulfanilate crystal. It is characterized by that it adopts a vibration fluidized bed drying machine as drying equipment, a sterile dried hot air can be fed into the bottom portion of said vibration fluidized bed to continuously heat and dry the potassium acetosulfanilate crystal, and a sterile dried cold air can be fed into the bottom portion of rear portion of said vibration fluidized bed to cool the heated and dried potassium acetosulfanilate crystal so as to make the temperature of potassium acetosulfanilate crystal be quickly reached to the required range.
Description
Technical field
The present invention relates to a kind of acesulfame potassium crystalline drying mode, refer more particularly to a kind of continuous drying mode that can carry out continuously.
Background technology
Acesulfame potassium is a kind of sweeting agent that is widely used in food, beverage industry.Advantages such as this compound has good water solubility, sugariness height, physico-chemical property is stable, synergism is strong, non-metabolic.
The acesulfame potassium crystal that relates among the present invention is that most of granularity is 20 orders-120 a purpose crystal, and water content is about 3-5%, and this part crystal needs after drying moisture to reach requirement just to pack.At present, drying mode and drying plant have a variety of, as tray drying, rotary flashing drying, spraying drying, air stream drying, belt drying etc.It is not too desirable that but these drying modes apply to acesulfame potassium crystalline drying.Part thermo-efficiency is too low, can not continuous production; And the other drying mode, as air stream drying, easy broken crystal causes a large amount of dust acesulfame potassiums, can't satisfy the requirement of acesulfame potassium crystal size.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of can serialization production, heat transfer efficiency is high and not broken acesulfame potassium crystalline drying mode.
For solving the problems of the technologies described above, the technical solution used in the present invention is to adopt the dry acesulfame potassium crystal of Vibratingfluidbeddrier.
Vibratingfluidbeddrier is to produce exciting force by vibrating motor to make machine vibration, material bounds forward on given exciting force direction, and input warm air in the bed end makes material be in fluidized state simultaneously, and material particles fully contacts with hot blast, carry out violent heat and mass transfer process, thermo-efficiency is higher.During work, can control the frequency of vibrating motor and the temperature of warm air well, make the acesulfame potassium crystal when bounding forward, produce less frictional force, so that crystal can be broken.
When the crystal of acesulfame potassium was discharged by Vibratingfluidbeddrier, temperature was higher, can not directly pack.As adopt naturally cooling, and consuming time longer, can not realize serialization production.Therefore, further technical scheme of the present invention is: can adopt secondary or two-stage drying mode.The secondary drying mode is meant two Vibratingfluidbeddrier series connection, wherein preceding road---or claim to import aseptic heated drying air at the bottom of the one-level vibrated fluidized bed bed, acesulfame potassium crystal moisture is lost rapidly; Back road---or claim to import aseptic dry freezing air at the bottom of the secondary vibration fluidized bed, make acesulfame potassium crystalline temperature reach room temperature after, just can directly pack.The two-stage drying mode refers to a vibrated fluidized bed is divided into two sections, preceding road---or claim import aseptic heated drying air at the bottom of the vibrated fluidized bed bed the last period, and acesulfame potassium crystal moisture is lost rapidly; Back road---or claim to import aseptic dry freezing air at the bottom of back one section vibrated fluidized bed bed, make acesulfame potassium crystalline temperature reach room temperature after, just can directly pack.
Advantage of the present invention is: (1) heat transfer efficiency height can be continuously produced.(2) not broken acesulfame potassium crystal.(3) the acesulfame potassium crystal prevented from caking that adopts this mode drying to obtain.
Embodiment
Below in conjunction with specific embodiment technical solutions according to the invention are further described.
Embodiment 1: the acesulfame potassium crystal, and moisture 4.5% (dry weight-loss method records), order is counted the 30-100 order.Material temperature this moment is 25 ℃, make material enter the translational vibration fluidized-bed of secondary drying mode by oscillating feeder, import 100-120 ℃ aseptic heated drying air at the bottom of the one-level vibrated fluidized bed bed, 5-25 ℃ of aseptic dry freezing air of input at the bottom of the secondary vibration fluidized bed.Behind dry the end, acesulfame potassium crystal moisture 0.3% (dry weight-loss method records), order is counted the 30-100 order, 27 ℃ of temperature of charge.
Embodiment 2: the acesulfame potassium crystal, and moisture 4.0% (dry weight-loss method records), order is counted the 30-100 order.Material temperature this moment is 25 ℃, make material enter the translational vibration fluidized-bed of two-stage drying mode by oscillating feeder, import 100-120 ℃ aseptic heated drying air at the bottom of one section vibrated fluidized bed bed, import 5-25 ℃ aseptic dry freezing air at the bottom of two sections vibrated fluidized bed beds.Behind dry the end, acesulfame potassium crystal moisture 0.2% (dry weight-loss method records), order is counted the 30-100 order, 28 ℃ of temperature of charge.
Claims (2)
1, a kind of acesulfame potassium crystalline continuous drying mode; it is characterized in that: adopt Vibratingfluidbeddrier as drying plant; aseptic heated drying air is imported at the bed end at vibrated fluidized bed, the acesulfame potassium crystal is carried out the heat drying of serialization.
