Dongfeng Dolica D7 4x2 8,500 L Milk Tanker with CIP

This Dongfeng Dolica D7 milk tanker has an 8,500 L horizontal oval tank divided into two compartments. Independent rotating CIP cleaning balls serve each compartment, with the control valves grouped in a rear operation box. Built-in milk hoppers form part of the tank arrangement, and two food-grade manholes provide inspection and cleaning access.

The fully polished inner tank uses 3 mm SUS304-2B food-grade stainless steel, with 1 mm stainless outer cladding. Insulation consists of 70 mm sprayed polyurethane foam and 10 mm rubber thermal cotton. Milk is discharged through a 51 mm port with customizable fittings. Lead sealing devices are fitted at the manhole covers, unloading ports and valve boxes; a stainless anti-slip walkway and detachable ladder provide tank-top access.

Power comes from a Yuchai YCY30165-60 Euro 6 engine producing 165 hp, paired with a six-speed Wanliyang manual gearbox. The 4x2 chassis has a 3,800 mm wheelbase, 5,200 kg curb weight and 6,600 kg rated payload. Overall dimensions are 6,900 × 2,350 × 2,800 mm. Air brakes with ABS, air conditioning, electric windows and power steering complete the vehicle configuration. With that payload the tank usually runs part-full, so the two compartments are handy for keeping milk from different farms apart.
