Scientific Lab & Dairy Tech

A 1000 LPH Milk Pasteurizer is a fully integrated, medium-capacity processing system designed to heat-treat raw milk to ensure safety, extend shelf life, and preserve nutritional quality. Ideal for dairy farms, milk collection centers, small to mid-scale dairy processing units, and food industries, this system consistently processes 1,000 liters of milk per hour through controlled heating and cooling stages.

The pasteurizer typically operates using the HTST (High Temperature Short Time) method, where milk is rapidly heated to a preset temperature—commonly 72–75°C for 15–20 seconds—to eliminate pathogenic microorganisms. It is then quickly cooled to storage temperature, helping maintain taste, freshness, and essential nutrients.

Built with food-grade stainless steel (SS304 or SS316), the unit includes a plate or tubular heat exchanger, balance tank, centrifugal feed pump, temperature and flow controls, and an automatic or semi-automatic control panel. Its energy-efficient design ensures low running costs through heat regeneration, where outgoing hot milk preheats incoming cold milk.

The system is compact, hygienic, easy to clean with CIP (Clean-in-Place) compatibility, and engineered for reliable, continuous operation. It ensures consistent pasteurization results with accurate temperature control, safety interlocks, and minimal operator intervention.

A Curd Making Machine is a specialized stainless-steel unit designed for the controlled fermentation of milk into curd (yogurt or dahi) under hygienic and consistent conditions. It is an essential component in modern dairy plants for producing uniform, high-quality curd on a commercial scale.
