Steripig Product Recovery System

Application

The Steripig Product Recovery System is ideal for the recovery of any product remaining in a pipeline at the end of the transfer process. As this product can be of a high value the PIG system recovers the product removing it from the pipelines and preparing the pipeline for a CIP process. Another benefit is the reduction of the fluid sent to the sewage treatment plant that results in saving energy and water.

The main application of the system is viscous media. Among the products treated there are gels, creams, ointments, emulsions and other products of high value in the pharmaceutical or cosmetic industry.

The STERIPIG system offers a completely hygienic product recovering solution because no component enters or leaves the installation. The sphere is positioned by external magnet. During the CIP process, when the flow rate is sufficient, the sphere gets free inside the launcher or receiver avoiding any dead leg zones between the pipeline and the sphere.

The system includes a launcher, a receiver, a PIG (a sphere), two position detectors (one for the launcher and the other for the receiver), four automatic butterfly valves and two KH three way valves.

The process starts locating the sphere in the launching position. Then the sphere is driven by a propellant (normally compressed air) down the pipeline to the receiver recovering any product left in the pipeline. When recovery is complete, the PIG is situated at the receiver and all the installation can be cleaned by CIP, the PIG can also be cleaned during the CIP routine. The CIP process is finished, the sphere is placed again into the launcher leaving the plant ready for the next production process.

Product Recovery System

The Product Recovery System plays a critical role in cleaning process lines and minimizing product losses at the same time. The process of cleaning process lines is important to meet hygiene standards, but product losses that occur during this process cannot be ignored. The product recovery system increases process efficiency by meeting these two important requirements together.

This system enables the recovery of valuable end product in process lines. In this way, losses occurring during production are minimized and product waste is prevented. Additionally, the product recovery system significantly reduces the process water consumption required to clean the process lines. This provides both a more environmentally sustainable production process and savings in operating costs.

The product recovery system can have various levels of automation. Fully automatic systems enable processes to be carried out largely automatically, minimizing human intervention while increasing operating efficiency. Semi-automatic or manual systems may be more suitable for smaller businesses or certain products.

As a result, the product recovery system ensures the cleaning of process lines by meeting hygienic standards, while minimizing product losses and increasing operating efficiency. This system plays an important role in industrial production processes and contributes to an environmentally and economically sustainable production practice.
