Cup Filling Sealing Machine (Curd / Yogurt/ Shrikhand)

The automatic curd and lassi cup filling machines are specialized packaging systems designed specifically for dairy and similar liquid or semi-liquid products. They are engineered to maintain hygiene, reduce labor dependency, and ensure high production throughput with precision. Below is a comprehensive overview of these machines, including their design, working principles, typical features, and available configurations.

Overview and Applications

These machines are commonly employed in the dairy industry for packaging products such as curd, lassi, yogurt, dips, and similar beverages. They are also versatile enough for filling other freely flowing or viscous products (e.g., fruit juices, honey, or even certain sauces) as long as the viscosity is suitable for gravity-based or pressure-assisted filling.

Types of Machines

Rotary Cup Filling Machines

Design: These machines usually operate on a rotary platform that indexes cups through various stations. Each station is responsible for a specific task like cup pickup, filling, lid or foil placement, and sealing.

Capacity: They generally offer production speeds in the range of approximately 2400 cups per hour, though specific models can be designed for higher throughput.

Example: PWS Engineers’ model (CF600 X 2P) is a rotary system that automates the entire process—cup dropping, sensing, filling by gravity, foil/lid placing, heat sealing, and cup ejection. All contact parts are made from SS 304 food grade material, ensuring safe contact with edible products

Linear Cup Filling Machines

Design: In contrast, linear machines handle cups on a conveyor system. They often feature a servo-driven indexing system with a multi-head configuration that allows simultaneous filling and sealing at multiple stations.

Capacity: These machines can reach output levels of up to 6000 cups per hour, making them ideal for high-volume production environments.

Example: The LF5 model by PWS Engineers is a linear variant, characterized by its fully automatic processes, high-speed operation, and high precision (filling accuracy typically within ±1% of the desired volume).

Semi-Automatic Solutions

Design: For smaller operations or where manual intervention is desired at certain stages, semi-automatic machines provide a balance between automation and human oversight. They often feature automated cup release and sensing systems, but might require operators to load or unload the product.

Example: Om Pack Machinery offers a semi-automatic lassi cup filling and sealing machine designed for volumes ranging from 100 ml to 400 ml. This model uses a stainless-steel construction and is tailored to meet the demands of smaller production lines while ensuring consistent quality
