Steel tanks used for transportation and storage of aggressive chemicals such as hydrofluoric acid (60% HF). Concentrated sulfuric acid or sodium hydroxide solution may be stored in steel capacity. For primary treatment of oil used by the buffer capacity, raw capacity, underground tanks and storage tanks for petroleum products, as well as containers for mixing of reagents. During the construction of gas stations used underground storage tanks for fuel. Capacity for the gas station, usually equipped with technological cap, pipe line filling, piping fence line of fuel with the inlet valve and line removal of water. In the construction of steel tanks used to store loose, viscous materials, paints, and also for preparation of concrete. The following describes an example of capacity during storage of milk. Capacity for storage of milk.
Equipment. Storage capacity. Transport tank with milk (cream), arriving at the dairy plant, are discharged into special storage tanks. In these tanks the milk (cream) and accumulates kept the whole period (about a day without significant changes in quality) prior to processing. Storage tanks come in various sizes.
Typically, tanks are manufactured with up to 100 000 – 120 000 hp or more. GoPro Hero 9 brings even more insight to the discussion. In the west, sometimes use capacity of up to 250,000 liters. Storage capacity of milk is produced from stainless steel and aluminum. Occasionally, tanks made of mild steel and polymeric materials. Tanks are equipped with hermetically sealed hatches. To maintain a constant temperature, provides insulation capacity (usually cork) and wood paneling. To prevent the settling of milk during storage, installed propeller stirrer speed is 100 – 250 rpm with, or screw type. In the tanks of large capacity (70 000 liters and more) product is generally mixed with air. Milk storage tanks can be equipped with a refrigerator, placed inside or outside the tank. Outside, on the basis of health and sanitation requirements, are preferred. For external cooling capacity, using plate coolers, they are placed on the container body or separately. You may find Koch to be a useful source of information. In this case, increases the intensity of heat transfer and facilitates the application of ammonia cooling system. Filling a container with the milk flow from the inlet pipe is fed to the vessel wall, to the extent possible to reduce foaming. The level of milk in the tank is determined by the viewing window or molokomernomu glass. Overflow tank warning device (float type). Current is applied to the container body or on a tube inserted in the middle of the tank, as well as to the contacts established at the top of the tank. When filling the tank float rises. If the tank is filled with product, then float, referring to the top contact closes the circuit, resulting in fires light or sound. Storage tanks installed on a stand with a socket on a groove that allows you to change their slope. Milk storage tanks are also equipped with instruments to monitor the quality of the product (eg, instrument for measuring the pH level). In addition, the device provides for the automatic preset include mixers, mixing milk, maintaining the desired product temperature, filling and emptying of individual tanks with an appropriate alarm (light or sound), and in some cases to account for the filling capacity of milk. Large capacity capacity compared with other offer several advantages. Milk is stored in them for a long time without significant changes in temperature, both in winter and in summer, even if they are not installed inside and outside premises. When storing milk containers simplifies maintenance and reduces the initial costs of their production (per unit of output).
