To compete with larger local dairies, small dairies need to make sure their product meets, or even exceeds, the quality of the larger industry players. Having the right equipment on site can ensure that the milk stay in top quality until it is picked up by the hauler and delivered to the buyer. This is where your cooling tanks come into play. The following guidelines can help ensure you have the best system in place for your dairy.
Types of Storage Tanks
First and foremost are your bulk tanks. These tanks are the primary storage system for your dairy, so you want to choose wisely. There are three general designs to choose from:
Open tanks. These generally are available in smaller sizes, suitable for smaller dairies.
Closed tanks. These are available in mid-range to larger sizes, suitable for some small, productive dairies.
Silos. These are the largest option and typically only used by large commercial dairies.
Used Tanks
It is possible to purchase these tanks used, which can result in major savings on your dairy's start-up cost. Tanks should be made of stainless steel, and they should not show any major dents or damage. A complete cooling tank will actually consist of two steel tanks – an inner and an outer. Both require a full inspection. You will also need to verify that the tank control panel is fully operational and that the cooling elements are in working order. Use a digital thermometer to verify that the tank's built-in thermostat is working properly.
If you are considering a closed tank, make sure the clean-out access port is fully operational. This port resembles a manhole on top of the tank. It should have a rubber gasket around the opening to ensure a tight seal when closed. The access port must also open and close easily, so that one can easily access the inner tank for regular cleaning and inspection.
Agitator Mixer
The agitator mixer assembly keeps the milk moving inside the tank at all times during storage. This is a vital component of any tank. By constantly agitating the milk, it not only ensures that you have a homogenous product, but also that the liquid is kept to an even temperature throughout. In other words, it prevents warm zones from developing. Most newer tanks have systems in place that notify you if an agitator malfunctions. Some agitator manufacturers also offer after-market accessories that allow you to update the agitators so you can monitor them without opening the tank.

Hello, I am Keesha Rhames. I would like to talk to you about metal fabrication equipment used in manufacturing plants. Metal fabrication requires the use of rolling, melting and cutting equipment of all kinds. The type of metal used for each product influences the equipment requirements for the manufacturing process. I will share information about metal choices and alternatives on this site. I will also discuss the use and repair of fabrication equipment. In particular, I will talk about maintenance needs of each type of equipment. I hope you will visit my site often to learn about this interesting subject. Thank you for coming by.
