Cold and Hot Urn

Cold and hot urn is also known as aging tank, has the characteristics such as energy-saving, noise reduction, corrosion resistance, strong production capacity, easy cleaning. It is a kind of stainless steel tank and widely used in dairy industry, food, pharmaceutical, chemical, beverage and other industrial departments to heat, cool, insulate sterilization processing or store slurry. Especially suitable for the pasteurized milk, and is the necessary equipment in ice cream production line.

Classification of Cold and Hot Urn

1. According to Structure: opening on the head & ramp bottom, opening on the head & conical sealed head on the bottom

2. According to Heating Type: there are Steam Heating and Electric Heating

3. According to Volume: there are 100L-1000L, also can design and facture in accordance with customers’ requirements.

Structure of Cold and Hot Urn

Structure: the interior, jacket, insulation layer, the outer foreskin, speed reducer, agitator, thermometer and so on.

The interior: stainless steel SUS304, mirror-polished surface.

Jacket: the A3 or 1Cr18Ni9Ti steel plate, strengthen circle spiral device, the cold water from bottom to top (without pressure), to achieve the best heating and cooling purposes.

Insulation group: stainless steel plate cast into scales, insulation layer use polyurethane or mineral wool to keep the temperature, achieve insulation effect.

Speed reducer：cycloid planetary reducer, fixed in the tray of the beam, a shaft gear wheel connect with the impeller flexibly for easy removal and cleaning.

Thermometer: specification 100C-1000C, installed on the beam, straight out to minimum medium position, makes sure that can indicate temperature even when the liquid material to the lowest position, to achieve sterilization and aging purposes.

Usages of Cold and Hot Urn

It is widely used in dairy industry, food, pharmaceutical, chemical, beverage and other industrial departments to heat, cool, insulate sterilization processing or store slurry. Especially suitable for the pasteurized milk, and is the necessary equipment in ice cream production line.
