Prevent Damage By Use Of Milk Tank And Silo

By Tammie Caldwell


Farmer who rear dairy cattle in large scale or in ranches they ought to have big storage facilities to temporarily store their products awaiting transportation. The facilities include big tanks for holding and cooling lacteal secretion of cows until the haulers come and pick it up, the product are maintained under very cold temperatures to avoid damage. Cooling facilities are the most important items in a dairy farm. So farmers should invest in milk tank and silo to maximize their profit and minimize damages.

Dairy products need proper storage system because they are highly perishable products. Storage containers are designed to have conical or flat bottom mounted on flexible legs. Effective and proper insulation makes storage containers suitable for storing cream, milk and many other dairy products to keep them fresh.

Cooling facilities and more specifically the tanks are of two types. They are either the open tanks which store around one hundred and fifty to two hundred and fifty liters or closed facilities which accommodate large amount of milk around one thousand to ten thousand liters.

After milking your cows the next stop is storing it in the storage silos which are refrigerated and are of several sizes and shapes. The lacteal secretion is stored at very low degrees in the cooler but only forty eight hours or less. Silos and containers are agitated to ensure the content is cold and to prevent milk from separating from fat.

The containers are constructed with two walls made of steel, the walls are some few inches apart from each other, and space in between them is filled with foam known as polyurethane. This foam is used to regulate the temperature from outside and inside the container.

To facilitate and accelerate rapid and adequate cooling of all the content inside a storage facility, the container is fitted with one or two agitator. To make sure that entire content in the container is of uniform temperature and homogeneous, it is recommended to stir the content regularly.

There is a forty centimeter manhole on top of every cooling container that is closed. This is very necessary because it allows for systematic cleaning and thorough inspection of interior containers whenever necessary. This manhole is supposed to be covered using lid and water tight sealed using rubber ring. Also on top of this big container there are two to four pipes installed to serve as inlets.

Direct expansion is one of the types for cooling, here a container is fitted with pipes carrying refrigerant which are attached to the outside chamber. Direct expansion cannot be carried out in the absence of content or lacteal secretion inside the container, in case it is done without, walls of the container will automatically freeze. The silo is quickly cooled as warm content flows in. The container is then cooled at a slow rate to maintain that low temperature.

There is supposed to be an outlet at the bottom of container and fitted with a valve. All cooling tanks have thermometer which allows for regular temperature inspection, some container have automatic systems of cleaning itself using hot water, cold water and an alkaline fluid used for cleaning.
