Abstract
The invention relates to a mixed starch airflow dryer, wherein a heat exchanger of the dryer is connected with a drying pipe and a batch feeder is connected with the drying pipe. The dryer further comprises an exhaust gas exhaust duct which is connected with the drying pipe by virtue of a draught fan, the exhaust gas exhaust duct is connected with a cyclone separator which is connected with a material collector, the heat exchanger is used for inputting heat energy to the drying pipe, wet starch and hot gas flow cocurrent in the drying pipe so as to be dried for the first time by negative pressure drying; materials dried primarily enter into the exhaust gas exhaust duct by virtue of the draught fan and flows concurrent with exhaust gas. The materials are secondarily dried by heat energy of exhaust gas by positive pressure drying. The wet starch dried by negative and positive pressures passes through the cyclone separator, the material collector and a packaging machine to obtain a finished product. By using the dryer provided by the invention, the heat energy in exhaust gas can be fully utilized, so that the energy waste is reduced and the equipment capacity is improved.
Description
Technical field
The present invention relates to a kind of starch factory drying plant, specifically a kind of hybrid starch airflow dryer.Background technology
At present, starch factory starch is dried negative pressure or the malleation airflow dryings that adopt single-stage more, the wet starch that by water content is 40% left and right mixes with hot gas flow, and complete heat exchange at course of conveying, waste gas is extracted out through induced draft fan, the waste gas of extracting out still has higher heat energy, can not be utilized, thereby cause a large amount of energy dissipations.
Summary of the invention
For the above-mentioned weak point of prior art, the invention provides a kind of hybrid starch airflow dryer, it can make the waste heat in waste gas be fully used, thereby reduces energy dissipation, improves the production capacity of drying plant.
The present invention is by achieving the above object by the following technical solutions: a kind of hybrid starch airflow dryer, comprise heat exchanger, batch charger, dry pipe, induced draft fan, cyclonic separator and loading head, described heat exchanger is connected with oven dry pipe, batch charger is connected with oven dry pipe, also comprise waste gas exhaust duct, drying pipe is connected with waste gas exhaust duct through induced draft fan, waste gas exhaust duct is connected with cyclonic separator, cyclonic separator is connected with loading head, heat exchanger is inputted heat energy to drying in pipe, wet starch and hot gas are dried for the first time drying in pipe also stream, this part is negative pressure drying, material after first drying enters in waste pipe and waste gas stream by induced draft fan, utilizes the heat energy of waste gas to carry out secondary drying, and this part is positive pressuring drying, and wet starch draws finished product through negative, positive pressing dry after dry by cyclonic separator, loading head, wrapping machine.
Describedly negative, positively press dry dry to be waste gas that suction type airflow drying is for the first time discharged for positive-pressure type airflow dryer for the second time, to utilize the heat energy in waste gas again wet starch to be dried.
Outstanding technique effect of the present invention is:
1, the heat in waste gas is fully utilized, and reduces single ton of energy material consumption.Compare with single-stage negative pressure or the malleation equipment of identical baking dry tube diameter, production capacity improves 1 times nearly.
2, starch flow is pulverized after induced draft fan, even the increasing of the index such as whiteness, fineness of starch.
Brief description of the drawings
Fig. 1 is the structural representation of hybrid starch airflow dryer of the present invention.
Embodiment
By drawings and Examples, technical scheme of the present invention is described further below.
As shown in Figure 1, hybrid starch airflow dryer of the present invention, comprise heat exchanger 1, batch charger 2, dry pipe 3, induced draft fan 4, cyclonic separator 6 and loading head 7, described heat exchanger 1 is connected with oven dry pipe 3, batch charger 2 is connected with oven dry pipe 3, also comprise waste gas exhaust duct 5, drying pipe 3 is connected with waste gas exhaust duct 5 through induced draft fan 4, waste gas exhaust duct 5 is connected with cyclonic separator 6, cyclonic separator 6 is connected with loading head 7, when work, heat exchanger 1 is to drying pipe 3 interior input heat energy, wet starch and warm air are dried for the first time drying in pipe 3 also stream, this part is negative pressure drying, material after first drying is entered in waste gas exhaust duct 5 and is also flowed with waste gas by induced draft fan 4, utilize the heat energy of waste gas to carry out secondary drying, this part is positive pressuring drying, and wet starch draws finished product through negative, positive pressing dry after dry by cyclonic separator 6, loading head 7 and wrapping machine.
