Milk Silo Tank

The milk silo is a kind of storage tank for heat preservation and storage of raw milk. It consists of a round stainless steel inner cylinder and a stainless steel outer shell. The middle layer is filled with polyester foam as a thermal insulation layer, which is conducive to heat preservation and storage. The milk stored in the tank will not form fat floating, and the upper part is equipped with a thermometer, which is convenient to measure the temperature of the milk in the tank. The milk is transported to the dairy processing plant where the temperature cannot exceed 10°C and is usually cooled to 4°C with a plate cooler.

Tank design requirements: SUS304 material, PU insulation, 3 layers with jacket cooling to prevent the temperature of the milk in the silo tank from rising. Good constant temperature performance is required. Generally, after 24 hours of storage, the temperature rise of milk should not exceed 2-3 °C. The tank is equipped with a side stirrer, liquid level gauge, temperature sensor, milk inlet and outlet, ice water inlet and outlet, stainless steel ladder, guardrail, sight glass, oval side manhole, and CIP cleaning device.

Large milk silo tank volume is between 15KL~200KL, the tank body is made of SUS304-2B or SUS316L stainless steel, the storage tank has good thermal insulation performance, and can be widely used in dairy, beverage, wine, petrochemical and other industries liquid material storage.

The tank body is made of food-grade SUS304-2B or SUS316L material, the inner layer of tank bottom isδ4.0mm, the inner layer of tank body isδ3mm, the outer shell isδ2mm, the jacket isδ1.5mm, the thickness of polyurethane foam insulation is 100mm, and the temperature of the fresh milk in the tank within 24 hours is ≤±1.5℃. Stainless steel plate surface film protection, weld passivation treatment or polishing treatment.

The tank body has a vertical cylinder, the top cone top, the taper is 30, the bottom cone is low, the taper is 30, and the milk outlet is equipped with a rotating plate.

There is an ice water jacket at the bottom of the tank and 1.5 meters below the tank body, which can pre-cool the tank before milk collection, and can also be used for secondary cooling when the milk is stored for a long time. The tank base is 304 stainless steel enclosure, thickness is 12mm. The tank body is equipped with a reinforced structure.

The propelling stirring device is used to ensure that the fat does not float and the temperature of the milk in the tank is uniform under the condition that the milk is not damaged. Speed ​​960 rpm, motor ABB.

The breathing hole is located on the top of the tank, and is connected to the room through a pipeline. The material is SUS304. It is equipped with a cleaning device. There are fly-proof and dust-proof nets at the milk inlet.

The top of the tank is equipped with a rotary cleaning ball, with a large flow and a cleaning pipeline of. It ensures that the whole tank is cleaned without dead ends, and the lower part of the agitator is also equipped with a cleaning ball to clean the lower part of the tank.

The milk inlet and outlet are made of SUS304 stainless steel pipes, equipped with APV inlet and outlet anti-mix valves, and the pipes are insulated.

The milk level of the milk silo adopts a static pressure liquid level sensor, and the amount of milk in the milk silo is directly displayed in the form of weight, which is intuitive and clear, and equipped with upper and lower limit protection function of liquid level.

The milk temperature of the silo tank is measured by the temperature sensor, which is directly displayed, and has an automatic alarm function.

The bridges, guardrails and ladders on the milk silo tank are SUS304 stainless steel.
