Propack Technologies is a leading manufacturer of toothpaste manufacturing plant and machinery, offering a complete solution for the production of semi-solid emulsions like toothpaste. Our toothpaste manufacturing plant consists of three different phase vessels - a water phase vessel, a wax phase vessel and a main mixing vessel. These vessels are equipped with various components such as an emulsifier/homogenizer, a vacuum pump, a transfer pump, storage and buffer vessels and a CIP module. All our vessels are made of SS316L grade material and fabricated as per cGMP guidelines. The plant can be completely automated with pneumatically operated valves for aseptic manufacturing.

Water phase vessel

Water Phase Vessel The water phase vessel is where all the aqueous phase mixing of ingredients is carried out with water or similar material as the solvent. The vessel could be jacketed for heating and cooling of the solution in the vessel. The temperature variation of the vessel could be achieved by steam & chilled water or electrical heating arrangement according to the availability of utilities at the customer’s facility. For uniform mixing, a propeller type stirrer is utilized along with baffles to prevent vortex formation. Product inlet into the vessel can be achieved via vacuum suction for minimum contamination. Similarly, solid ingredients can also be introduced into the solution at vacuum pressure. Solid ingredients can be introduced into the vessel via an additive hopper at the top of the vessel or a suction port situated at the bottom of the vessel. After obtaining the satisfied composition the contents of the vessel are transferred to the main mixing vessel.

Wax phase vessel

Wax Phase Vessel The wax phase vessel is where all oil/wax phase mixing is carried out with wax as the main solvent. The vessel is usually jacketed for heating of the wax to improve solubility at elevated temperatures. The temperature variation of the vessel could be achieved by steam & chilled water or electrical heating arrangement according to the availability of utilities at the customer’s facility. For uniform mixing, a saw-tooth cutter type stirrer is utilized in this phase vessel. Product inlet into the vessel can be achieved via vacuum suction for minimum contamination. Similarly, solid ingredients can also be introduced into the solution at vacuum pressure. After obtaining the satisfied composition the contents of the vessel are transferred to the main mixing vessel.

Main Manufacturing vessel

Main Manufacturing Vessel The main manufacturing vessel is where the main mixing of the contents in the water phase vessel and the wax phase vessel is done at appropriate temperature. The temperature variation of the vessel could be achieved by steam & chilled water or electrical heating arrangement according to the availability of utilities at the customer’s facility. Usually, the main mixing vessel is provided with a top mounted Contra type anchor agitator to stir the product for uniform temperature transfer and minimizing lump formation. The agitator is also equipped with Teflon scrapers for scraping of material from the walls of the vessels. Apart from the agitator, a toothpaste mixing machine or a homogenizer is provided at the bottom of the vessel for emulsification of the liquid-liquid mixture to a uniform composition. Propack technologies’ toothpaste mixing machine or homogenizer is designed to reduce particle size to less than 5 microns. After attaining the desired composition and viscosity of the product, the contents are transferred into a storage vessel through a flush bottom diaphragm valve to minimize product holdup in the tank.

The operations of various pumps, pneumatically operated valves (in case of automated operation) and mixers is carried out through the main control panel. The panel is made out of SS304 grade material and consists of various safety lock systems like the Emergency stop and Mains supply indicators for safe work and extended component life. The vessels are connected to each other via interconnecting pipelines manufactured as per cGMP norms and connected with sealed tri clamp connection.
