Description
Technical field
The present invention relates to a kind of microwave method and produce the manufacture method of low moisture starch, belong to low moisture
The manufacture method technical field of starch.
Background technology
At present, produce low moisture starch and mainly have 3 kinds of methods: one is pneumatic conveying drying method, and two are
Constant-pressure and high-temperature roasts method, and three is that vacuum roasts method.In pneumatic conveying drying method, owing to material is at height
In speed air current flow, unavoidable phase mutual friction produces electrostatic, there is certain potential safety hazard.And show
Two kinds had roast the method producing low moisture starch, due to the limitation of reaction pot volume, make
Become the moisture between different pot time to there is certain difference, thus unit batch is too small (as used
Big volume always mixes device, and the most total mixed device volume is limited eventually, the most then strengthen and produce into
Originally) quality forming product is not sufficiently stable.And microwave method produces low moisture starch due to microwave certainly
Body can avoid the deficiency of above method to hot feature.

Individual/ware.
Preferably, described step 3 uses four sections of microwave drying ovens, four sections of microwave drying
It is 80 DEG C, 95 DEG C, 110 DEG C, 125 DEG C that case heating-up temperature sets gradually.
Preferably, in described four sections of microwave drying ovens, it is provided with temperature sensor, uses
Temperature in control microwave drying oven in real time.
Preferably, described material is spread on a moving belt by the thickness of 0.02 meter, transmits
Tape speed is set to 1.2 ms/min.
Preferably, described material is spread on a moving belt by the thickness of 0.025 meter, transmits
Tape speed is set to 0.9 m/min.
Beneficial effect: the microwave method that the present invention provides produces the manufacture method of low moisture starch, its
Advantage is as follows:
One, product quality is more stable: owing to whole production line realizes line production, automatization
Degree is higher, can monitor temperature of charge, moisture in real time simultaneously, and carries out omnidistance accurately control
System.Ensure the stability of product quality.
Two, energy-saving and emission-reduction: microwave treatment case, through strict matched design, makes microwave energy obtain
Coupling, energy is fully used, and can save energy for same production capacity compared with additive method
Amount 30%.Simultaneously because it is at relative closure that microwave method produces the whole production procedure of low moisture starch
In the environment of carry out, the most just can largely avoided the pollution of dust, reduce dust quick-fried
Fried risk.Most importantly the heating means of microwave method production low moisture starch are more traditional
Steam or oil heating, equipment itself do not produce any affect environment pollutant (include noise,
Dust, harmful exhaust etc.), it is a kind of heating means of environmental protection.
Three, automaticity is high, it is easy to control: microwave method produces the main work of low moisture starch
Process flow Dou Shi automatization: gravity system feed, the uniform stone of stone device, microwave are dry
The PLC of dry case selects Delta PLC to control, equipment is single break down time, it is possible to individually locate
Reason product, it is to avoid because the fault of equipment own causes product to be wasted.Microwave enclosure use external
The advanced online infrared temperature of multiple spot, installs the contactless temperature measurement on-line of import producing line
Instrument, grasps display temperature of charge in real time, thus realizes accurately controlling baking temperature, it is to avoid temperature
Too high affect product quality, technique initialization and Automated condtrol more in conveniently producing, can be carried out.This
Outer also employing PID regulates self energy control mode, reduces temperature fluctuation.Microwave power converts heat energy
Having instantaneity, heat material without thermal inertia, material is heated at once, otherwise material is just
Can not get microwave heat and stop heating.The most whole flow production line automaticity height is prone to
Operation and control.
Four, save area, improve working conditions: setting of conventional dry method low moisture Starch Production
Standby the hugest, need to take the biggest plant area.And microwave method produces low water
Divide its compact equipment of starch, take plant area the least, save the biggest spatial area.
Unpleasant noise, height will not be produced during microwave method produces low moisture starch simultaneously
The environment of heat, contaminated gas etc., which significantly improves working environment and labor condition.
