Paste kettle Machine – Frequently Asked Questions (FAQ)

What is the function of a Paste Kettle Machine?

A Paste Kettle Machine is used to heat, mix, and process viscous materials such as starch pastes, creams, gels, ointments, syrups, and sauces. The jacketed vessel provides uniform heating, while the agitator ensures consistent mixing and prevents lump formation or product burning.

What are the types of Paste Kettle Machines available?

Paste kettle machines are generally available in laboratory, pilot-scale, and industrial models. Based on heating method, they can be steam-heated, or electric-heated and are offered in GMP and non-GMP configurations.

What is paste in pharmaceutical applications?

In pharmaceuticals, a paste is a semi-solid dosage form containing a high percentage of insoluble solids dispersed in a suitable base. Pastes are commonly used for topical applications such as ointments, medicated creams, and protective coatings.

What is the working principle of a Paste Kettle Machine?

The product is heated through a jacketed vessel using steam or electric heating. An anchor or scraper-type agitator continuously stirs the material to ensure uniform heat distribution, prevent localized overheating, and maintain consistent product texture.

What materials are used to construct a Paste Kettle Machine?

Paste kettle working principle

The working principle of a Paste Kettle Machine is as follows:

Loading of Ingredients: The required ingredients, such as starch and water, are loaded into the kettle. The hemispherical vessel design ensures uniform heat distribution and efficient mixing.
Heating Process: Steam or thermal fluid circulates through the jacketed vessel, heating the product uniformly. This controlled heating process facilitates proper gelatinization and formation of a smooth paste.
Agitation & Mixing: An anchor-type or scraper-type agitator rotates within the kettle to mix the contents thoroughly, ensuring a homogeneous and lump-free product.
Temperature Control: The temperature is precisely regulated using a digital temperature controller to maintain the desired viscosity, texture, and product quality.
Discharge Mechanism: Once the paste reaches the required consistency, the kettle is tilted using a manual handwheel mechanism, allowing clean and controlled discharge of the product.
Cooling & Cleaning: After discharge, the kettle is allowed to cool and is cleaned as per hygiene and GMP guidelines. CIP-compatible designs enable efficient and thorough cleaning.

This working principle ensures consistent production of high-quality pastes, making the Paste Kettle Machine an essential piece of equipment in pharmaceutical, food, cosmetic, and starch processing industries.

Paste kettle machine in pharmaceutical industry

A Paste Kettle Machine, also known as a starch paste kettle or tilting paste kettle, is widely used in pharmaceutical manufacturing for the preparation of ointments, creams, gels, and paste-based formulations. The machine is designed to ensure uniform heating, controlled mixing, and hygienic processing in compliance with cGMP standards.

Design & Construction: The hemispherical, jacketed vessel ensures efficient heat transfer and uniform temperature distribution. Steam or electric heating enables controlled processing, while the robust stainless-steel construction supports long service life and easy cleaning.
Functionality: The Paste Kettle Machine performs simultaneous heating and agitation, allowing ingredients to be processed into a smooth, homogeneous paste. This ensures batch-to-batch consistency and uniform product quality.
Operation: Ingredients are loaded into the kettle and heated to the required temperature. An anchor-type or scraper-type agitator continuously mixes the formulation to maintain homogeneity. Once the desired consistency is achieved, the product is discharged through a controlled manual tilting mechanism.
Materials & Compliance: Product contact parts are manufactured using SS316 / SS316L stainless steel, while the overall design complies with current Good Manufacturing Practices (cGMP), ensuring hygiene, safety, and regulatory acceptance.

paste kettle machine diagram

As above figure reflect the kettle diagram and below are the list of kettle parts.

- Paste Kettle Body: To start with, you load ingredients into the main container.
- Agitator: The agitator, generally an anchor-type impeller, then mixes the ingredients thoroughly.
- Jacketed Design: Steam or thermal fluid next circulates through the outer shell in order to heat the contents.
- Temperature Controller: The temperature controller subsequently monitors and regulates the heat inside the kettle.
- Discharge Valve: You use the discharge valve at the bottom or side afterwards to remove the paste.
- Tilting Mechanism: You additionally tilt the kettle using a handle or handwheel for easy discharging.
- Motor: The motor therefore powers the agitator so as to ensure thorough mixing.
- Reduction Gear Box: The reduction gear box likewise regulates the speed and torque of the agitator.
- Butterfly Valve: The butterfly valve meanwhile controls the flow of ingredients or paste during processing.
- Heater: The heater furthermore provides additional heating if required.
- Cooling System: You use the cooling system to cool down the kettle once processing is complete.
- Cleaning Ports: The cleaning ports thereafter allow for easy access during the cleaning process.
- Control Panel: The control panel finally acts as the central interface for operating and monitoring the kettle functions.
