Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1-3:
a vacuum dehydration device for starch production comprises a vacuum adsorption bed 2, a belt type transmission system 3 and a spiral feeder 1, wherein the vacuum adsorption bed 2 comprises a gas dissipation chamber 21, a metal dense-pore plate 23 (a metal net cannot be used, and the adsorption force is reduced due to too strong air permeability) is laid above the gas dissipation chamber 21, side baffles 22 are arranged on two sides of the metal dense-pore plate 23, and the gas dissipation chamber 21 is connected with a plurality of vacuum air extraction pipelines 24; the transmission belt 31 of the belt transmission system 3 is overlapped and sewn by at least two layers of gauze and slides along the vacuum adsorption bed 2 by clinging to the metal dense hole plate 23; the belt type conveying system 3 is provided with a discharging device at the outlet side of the vacuum adsorption bed 2; a spiral feeder 1 is arranged on the inlet side of the vacuum adsorption bed 2 right above the inlet side; the discharge port 11 of the spiral feeder 1 is flat, and the width of the discharge port is smaller than or equal to that of the metal dense-hole plate 23.
Specifically, the discharging device comprises a turnover roller 33 and a scraping roller 34; the scraping roller 34 is provided with a plurality of scraping teeth 34a on the circumference, starch is in a block shape after being adsorbed and dried, the starch is crushed and separated from the transmission belt 31 after passing through the overturning roller 33, a small amount of residue is scraped by the scraping teeth of the scraping roller 34, when the discharging device is adopted, the conveying belt 35 can be arranged at the lower end of the discharging device to cooperate with the material to be conveyed away, if other discharging devices are adopted as the case may be (such as scraping plates or high-pressure air flow washing), a storage tank and the like can be arranged below optionally, and the selection is carried out according to the field and the like.
