Treatment of Silo – 2016

(Bhs. INDONESIA) Silo is a structure used to store bulk materials. Silo is commonly used in agriculture as a store of grain and forage crops. Outside of agriculture, silos used to store coal, cement, wood chips, and sawdust. There are three types of silo are widely used today, namely the type of towers, bunkers, and sacks.

In the loading of bulk materials in silos, mechanisms such as grain elevators conveyor (belt conveyors, air conveyors, bucket conveyors), auger and hopper depending on the type of bulk material is loaded. Charging is done from the top level, so that the first entry will be under. While making bulk materials is done from below.

Depending on the materials loaded, control the environment inside can vary. Control of moisture content in the air is required and adjusted to the equilibrium moisture content of the material if you want a long storage time. Control of the type and concentration of gas in the silo is required if the material readily reacts with certain gases like oxygen. Controlling gas levels is also needed if the silo is used for fermentation, aerobic and anaerobic. (Wikipedia: https://id.wikipedia.org/wiki/Silo)

Care silo in this case in the animal feed factory needs to be done so that the results of the product is not contaminated by pests. The first study was conducted site survey, and altitude measurements cubication silo.

Animal feed factory new stage of development still requires care from various aspects. All divisions have started their activities, ranging cheking feed ingredients, machinery, up to the development of other divisions. The process is carried out almost 24 hours a day. It also encourages contamination of animal feed ingredients that go into the silo, which is due to the project workers in and out freely.

Preparations include a sand snake, cover sheet, fumigants (sulfuryl fluoride), a board for a foothold, danger areas, danger line, rope, distribution pipes, brass pipes, hoses distribution.

Next is a silo according to altitude measurement, diameter, depth of feed materials and gas discharge lines for aeration. Preparation of brass pipe to plug in feed materials with a length of 3 meters and carried the brass connecting rod 3, the total depth is 9 meters to a depth of feedstuffs. While embedding is done in 6 points.

Transportation equipment is done manually, in the silo is not provided lift for goods resulting plant development is still done. Brass pipes and distribution pipes, hoses and distribution of portable equipment is done by using a retractable leash. While the tube fumigant on stage by two officers.

Climbing the ladder silo using manual, although there has been a safety for the people, should be done extra carefully, since the process is done in the late afternoon and early evening, and at that time the situation was wet rain.

Equipment ranging entered one by one through the hatch. The clerk began to enter the first rod brass pipes, rods connected to the second and third rod. Continue to be made of brass pipe connecting a hose to be connected to the tube distribution and fumigants.

Once it is done in a manner sealing the cover sheet overlay measuring the diameter of the silo, then cover sheet diseal using duct tape. Dust and dirt that meet silo slightly inhibit sealing, as dirty and somewhat difficult to cling. While the dust is scattered fairly stifling our noses.

Sealing is complete and the connection to the tube has also been completed, begin the most important stages, namely gassing. Before gassing carried out checks on the distribution of hoses and discharge lines for gas. Gas discharge lines using PE plastic from the hatch channeled down with the help of an exhaust fan.

Installation danger line and danger area was conducted, while workers on the project and the feed mill worked with a team to coordinate their working hours, considering the fumigant is applied very dangerous for humans, they are given the sense not to get closer to the fumigation area.

After gassing, the area allowed to stand for 24 hours. Monitoring is done and after the next day to do aeration and see pest control that is stored in the silo.
