520 lt open type, vertical milk cooling tank

The tanks we offer are durable and practical for rapidly, economically, efficiently, and consistently cooling large quantities of milk. Made of stainless steel, our milk cooling tanks are solid, durable, and efficient products that are assembled using laser welding. Thanks to the optimum speed rotating mixer motor, the milk in the tank cools evenly without freezing. Milk cooling tanks are available in capacities ranging from 150 liters to 2000 liters, making them the most economical choice for industrial use.

General Specifications:

• The material used in the mechanical components of the milk cooling tank (including the body and adjustable legs) is AISI 304 grade stainless steel.
• The laser-welded evaporator (rollbond) at the bottom of the tank is 2 mm thick.
• The outer wall thickness is 0.8 mm, and the inner wall thickness is 1.2 mm.
• A 30 rpm mixer motor of French origin, manufactured by Sirem, is mounted on the tank.
• The insulation foam is composed of 65% isocyanate and 35% polyol (ester-based) foam, with a minimum side insulation gap of 50 mm and a minimum bottom insulation gap of 100 mm.
• The design of the milk cooling tank ensures that no liquid remains inside during emptying. It is equipped with a DN50 butterfly valve for product discharge.
• There are no corners on any surface of the tank; the joining points are oval-shaped and welded with Argon (TIG) welding. The subsequent cleaning and polishing processes result in a flawless and smooth surface.
• The mixer propeller does not alter the structure of the milk and operates for approximately 2 minutes every 15 minutes to prevent the milk from freezing.
• R404A refrigerant is used for cooling.
• 2BII cooling class.
• It is designed to reduce the temperature of the milk from +36 ºC to +4 ºC within a maximum of 3 hours at an ambient temperature of +38 ºC.
• The compressor is protected from low or high voltage by a voltage protection relay installed on the electrical panel.
• The milk temperature can be easily read with the Dixell brand digital thermometer.

Cooling unit
Precise calculation of the cooling capacity of each tank ensures that the milk is cooled at the right time according to the milk producer’s needs. Our tank models are available in 2 or 4 milking versions for normal or high ambient temperatures (tropical and supertropical) and are available with imported compressors depending on the customer’s needs. All refrigeration units work with environmentally friendly gas R404A.

Evaporator
The tanks are equipped with a direct expansion evaporator welded with state-of-the-art laser technology and has the proper inclination to ensure the bottom is completely emptied. The mounting of the evaporator in the tank, its design, proper material selection and direct distribution of the heat of the milk, prevents the formation of icing, minimizes energy loss and ensures that there is no coolant leakage.

Thermal insulation
Tank insulation with environmentally friendly two-component polyurethane foam ensures that the milk is kept at the desired temperature and minimum energy consumption.

Dipstick
To measure the milk level and calculate the amount of milk in the tank, all tank models are equipped with a stainless steel measuring rod and a conversion chart in liters.

Easy cleaning
Thanks to the cover that can be opened fully upwards, the tank can be cleaned easily.

Electrical panel
The electrical control panel for cooling and mixing milk has an easy-to-read 3-digit display that makes the cooling tank easy to operate at the touch of a button. It is based on the Dixell electronic controller suitable for milk cooling systems and is equipped with an IP68 sealed temperature sensor (NTC) up to 110° C. The panel is IP55 certified and the electronic circuits are protected against water or water vapor ingress.

Perforated cover plate of the cooling unit
The stainless steel protective perforated cover ensures that small animals enter the cooling unit of the tank and dirt runs smoothly. Its easy removal provides direct access to the cooling unit for maintenance and repair.

Cover springs
The springs mounted on the back of the cover are designed to allow the cover to be fully opened and to prevent it from falling suddenly when it is open. (1 to 4 depending on the model)

Milk output
Milk cooling tanks are equipped with a DN50 stainless steel butterfly valve.

Agitator motor
Milk cooling tanks are equipped with agitator motors manufactured by the French company Sirem, rotating at 30 rpm to prevent milk icing. The motors are set to stop automatically when the tank cover is lifted.

Adjustable support legs
All tank models have adjustable support legs so that absolute leveling can be achieved even on uneven floors, which is a prerequisite for accurate measurement of milk.
