Abstract
The invention provides a production method for continuously drying corn steep liquor dry powder by belt type vacuum liquid, wherein a heating plate is arranged at the front section of a belt type vacuum liquid continuous dryer, a cooling plate is arranged at the rear end of the belt type vacuum liquid continuous dryer, corn steep liquor is conveyed onto a guide belt of the belt type vacuum liquid continuous dryer through a distribution pump, the guide belt slowly rotates through a variable frequency transmission system, the heat emitted by the heating plate changes the moisture of the corn steep liquor on the guide belt into steam to be evaporated, and the steam is discharged through a vacuum pump; the corn steep liquor is dried slowly in the conduction band; and when the corn steep liquor reaches the rear end of the dryer, the rear end cooling plate cools the dried corn steep liquor, the scraper cuts the material down and enters the discharging auger, and the corn steep liquor is crushed by the crusher to produce the corn steep liquor dry powder. The invention has the obvious advantages of vacuum and low-temperature drying in the production process, solves the safety problems of easy ignition and the like in the spray drying production process, simultaneously has low power consumption and low steam in the vacuum and low temperature, reduces the production cost, and has safe, continuous, clean and energy-saving production process.
Description
Technical Field
The invention relates to the technical field of feed processing and biological fermentation, in particular to a production method for belt type vacuum liquid continuous drying corn steep liquor dry powder.
Background
The production process of corn steep liquor dry powder production enterprises originally adopts a spray drying method for production, and because the phosphorus content of the corn steep liquor is high, the drying process is a safety accident that fire disasters and the like often happen due to high-temperature drying; the production process is discontinuous; the production field is difficult to clean; the consumption of electricity and steam is high, which causes the production cost to be higher. A production method for belt type vacuum liquid continuous drying corn steep liquor dry powder solves the requirements of safe production, continuous production, clean production and production cost reduction.
Disclosure of Invention
The invention provides a production method for continuously drying corn steep liquor dry powder by belt type vacuum liquid, aiming at the requirements of safe production, continuous production, clean production and production cost reduction in the production process of the corn steep liquor dry powder, and achieving the purposes of safe, continuous, clean and energy-saving production.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a production method for continuously drying corn steep liquor dry powder by belt type vacuum liquid is realized by adopting the following devices: the device comprises a corn steep liquor adjusting tank, a vacuum system, a feeding system, a belt type vacuum liquid continuous dryer, a cleaning system, a freezing system and a heating system. The method is characterized in that corn steep liquor is conveyed to a guide belt of a belt type vacuum liquid continuous dryer through a material distribution system, the guide belt rotates slowly through a variable frequency transmission system, the heat emitted by a heating plate changes the corn steep liquor moisture on the guide belt into steam to be evaporated, the steam is discharged through a vacuum pump, and the discharged wastewater is conveyed to a sewage treatment plant to be treated and discharged after reaching the standard; the corn steep liquor is dried slowly in the conduction band; and when the corn steep liquor reaches the rear end of the dryer, the rear end cooling plate cools the dried corn steep liquor, the scraper cuts the material down and enters the discharging auger, and the corn steep liquor is crushed by the crusher to produce the corn steep liquor dry powder.
Drawings
FIG. 1 is a schematic view of the process of the present invention.
In the figure, a 1-corn steep liquor adjusting tank, a 2-screw pump, a 3-heat exchanger, a 4-belt type vacuum liquid continuous dryer, a 5-vacuum pump, a 6-pulverizer and a 7-bin are arranged.
Detailed Description
High-concentration corn steep liquor (with solid content of more than 80%) is conveyed to a guide belt of a belt type vacuum liquid continuous dryer through a screw pump, the guide belt rotates slowly through a variable frequency transmission system, the heat emitted by a heating plate changes the corn steep liquor moisture on the guide belt into steam to be evaporated, the steam is discharged through a vacuum pump, and the discharged wastewater is conveyed to a sewage treatment plant to be treated and discharged after reaching the standard; the corn steep liquor is dried slowly in the conduction band; when the dried corn steep liquor reaches the rear end of the dryer, the rear end cooling plate cools the dried corn steep liquor, the scraper cuts the material into the discharging auger, the material is crushed by the crusher to produce the corn steep liquor dry powder, and the moisture of the finished corn steep liquor dry powder is generally controlled to be below 6%.
Claims (3)
1. A production method for continuously drying corn steep liquor dry powder by belt type vacuum liquid is realized by adopting the following devices: the device comprises a corn steep liquor adjusting tank, a vacuum system, a feeding system, a belt type vacuum liquid continuous dryer, a cleaning system, a freezing system and a heating system; the method is characterized in that corn steep liquor is conveyed to a guide belt of a belt type vacuum liquid continuous dryer through a material distribution system, the guide belt rotates slowly through a variable frequency transmission system, the heat emitted by a heating plate changes the corn steep liquor moisture on the guide belt into steam to be evaporated, the steam is discharged through a vacuum pump, and the discharged wastewater is conveyed to a sewage treatment plant to be treated and discharged after reaching the standard; the corn steep liquor is dried slowly in the conduction band; and when the corn steep liquor reaches the rear end of the dryer, the rear end cooling plate cools the dried corn steep liquor, the scraper cuts the material down and enters the discharging auger, and the corn steep liquor is crushed by the crusher to produce the corn steep liquor dry powder.
2. The method of claim 1, wherein the dried corn steep liquor is produced by a belt vacuum liquid continuous dryer.
3. The process of claim 1, wherein the moisture in the corn steep liquor is evaporated by heating to form water vapor which is then removed by a vacuum pump.
