V. Energy-saving technology for raw material processing, ingredient mixing, and granulation section in feed production operation
1, raw material processing
1) Turn off unwanted devices.
2) During the processing of feed, do not smash the raw materials more fine than required.
3) Choose a pulverizer model that can achieve the required particle size with minimal power.
4) Use a variable speed feeder to feed the material evenly and maintain a constant load on the mill.
5) Use an air assist system for the shredder system to increase production.
6) For steaming tablets and pleating, make sure that the steam is contained in the steam box and do not vent the steam into the atmosphere.
7) Some raw materials are classified before pulverization, and only the part of the raw materials to be pulverized is pulverized.
8) In the fine pulverization operation, the raw materials which are difficult to be pulverized and easily pulverized are mixed and then finely pulverized, whereby the fine pulverization efficiency can be improved.
9) Add grading equipment after initial pulverization and fine pulverization to reduce excessive pulverization of raw materials.
2, ingredients mix
1) Use the variable frequency variable speed controller for the screw feeder to keep the loader motor load stable and efficient.
2) The silo and scale should be designed to ensure that the material is completely discharged by self-flow without using a vibration discharge or mechanical unloading device.
3) Correctly set the ingredients and mixing cycle, and arrange the manual feeding and liquid adding operations reasonably to improve the efficiency of mixing and mixing.
3, granulation:
1) Use the AC variable speed controller on the feeder to adjust the feed amount to keep the regulator full load and high efficiency.
2) Use an AC variable speed controller on the conditioner drive to control the discharge speed and keep the material inside the regulator.
3) Use an automatic control system to control the operation of the granulation system and adjust the energy input as needed to meet preset operating conditions.
4) Use a cooler with a level controller such as a counterflow cooler to cool the pellet feed, as this cooler saves 20-25% of the air compared to a conventional horizontal cooler. Scientifically adjust cooling time and air volume to avoid excessive cooling.
5) Supply air from the coldest possible air source to the cooler areas of the cooler. • Allow air to flow through the centrifugal deduster at a rate that does not accumulate in the duct, resulting in proper static pressure to allow the fan to operate at an efficient point in its performance curve.
6) When using the granulator, scientifically adjust the rolling distance of the crushing roller to avoid excessive crushing and save energy.
6. Energy-saving technologies for extrusion, packaging, bulk shipment, warehousing, etc. in feed production operations.
1. Extruded
1) Use the AC variable speed controller on the feeder to adjust the feed amount to keep the regulator full load and high efficiency.
2) Use an AC variable speed controller on the conditioner drive to control the discharge speed and keep the material inside the regulator.
3) Use an automatic control system to control the operation of the extruder system and adjust the energy input as needed to meet preset operating conditions. Scientifically adjust the pressure and temperature in the extrusion chamber, correctly control the density and ripening degree of the expanded product, and avoid excessive ripening and energy consumption.
4) Correctly adjust and control the air volume and temperature in the dryer, scientifically use heat exchange equipment to recycle part of the hot air to improve energy efficiency.
5) Correctly adjust and control the air volume and temperature in the cooler to avoid excessive cooling and improve energy efficiency.
2, packaging section
1) Grouped packing bins and equipment are concentrated in one area to facilitate access to the materials to be packed and to transport the packaged materials and brackets. This requires very little personnel to observe and operate the device.
2) Material storage to be packaged should be arranged close to the packaging equipment and convenient for forklifts and other power vehicles.
3) In the cold season, isolate and only heat the area around the baling equipment.
4) Check for excessive air usage and air leaks.
3, bulk delivery:
1) Check for excessive air usage and air leaks from the pneumatic gate and vibrator.
2) Use gravity to remove the feed directly into the car from the silo.
4, warehousing:
1) The material arrangement in the warehouse should be the shortest and most direct route from packing to storage to loading and distribution.
2) There are enough storage rooms to keep the forklifts running and enough to place and carry out the product.
3) The arrangement or design of the warehouse should enable each product to be stored and issued on a first-in-first-out basis, without the need to remove the new goods before the old goods can be used.
Disposable Wear is to use film of spun-bonded non-woven fabric sewn together, one-time use, protective clothing is much used in the isolation between the human and the environment, can cut off liquid penetration of pollutants, have protective effect on the human body, can also be used as insulating clothing or isolation gown. With the development of the society, the purpose of the protective clothing is more and more widely, such as clean clean up, infectious diseases epidemic area of disinfection and isolation work, doctor daily protection, farm daily epidemic prevention and so on, the protective clothing can effectively prevent viruses and bacteria invasion or infection for staff.
