A khoya machine is a specialized piece of equipment used in the production of khoya (or khoa), a reduced milk product widely used in Indian sweets like Gulab jamun, barfi, and peda. The machine simplifies and automates the traditional process of simmering and evaporating milk to concentrate its solids. Here’s an overview of how a khoya machine works:

Working Principle of a Khoya Machine

1. Milk Loading
   • Fresh milk is poured into the machine’s heating pan or boiler.
   • Some machines are equipped with a pump system to load milk directly from storage tanks for large-scale operations.
2. Heating Mechanism
   • The machine uses a direct or indirect heating system, typically powered by gas burners, electric heating elements, or steam.
   • Indirect heating (e.g., steam-jacketed pans) helps avoid scorching and ensures even heat distribution.
3. Continuous Stirring
   • The khoya machine has mechanized stirring arms or paddles that continuously stir the milk during heating.
   • Stirring prevents milk from sticking to the surface of the heating pan, ensuring even evaporation and avoiding burning.
4. Evaporation of Water
   • As the milk heats, water content evaporates, leaving behind concentrated milk solids.
   • The machine maintains a consistent temperature to achieve the desired texture and quality of khoya.
5. Scraping Action
   • The stirring arms or paddles often have scrapers attached to their edges to prevent milk from forming a crust on the pan’s surface.
   • This action ensures thorough mixing and efficient evaporation.
6. Monitoring and Control
   • Some machines feature temperature and time controls for precision.
   • Operators can monitor the consistency of the milk to decide when to stop the process based on the type of khoya being made (e.g., soft, granular, or hard).
7. Collection of Khoya
   • Once the desired consistency is reached, the machine allows for the easy collection of khoya.
   • It can be scooped out manually or through an automated discharge system in advanced models.

Types of Khoya Machines

1. Manual Khoya Machine
   • Requires more operator involvement for stirring and monitoring.
   • Suitable for small-scale production.
2. Semi-Automatic Khoya Machine
   • Includes motorized stirring and heating but still requires some manual control.
   • Ideal for medium-scale production.
3. Fully Automatic Khoya Machine
   • Features automated feeding, heating, stirring, and discharge systems.
   • Perfect for large-scale, industrial production.

Advantages of Using a Khoya Machine

• Time-Efficient: Drastically reduces the time needed to make khoya compared to traditional methods.
• Consistent Quality: Ensures uniform cooking and texture in every batch.
• Hygienic Process: Reduces manual handling, minimizing contamination.
• Energy Efficient: Optimized heating mechanisms reduce fuel or electricity consumption.
• Versatile: Can be used for other purposes like making rabri, basundi, or ghee.

In summary, a khoya machine automates the time-intensive and laborious traditional process of reducing milk, ensuring consistent results and higher efficiency for sweet-making businesses or large-scale food production.

A ghee clarifier is a device or setup used in the production of ghee (clarified butter) to separate impurities, water, and milk solids from butter or cream, resulting in a pure, golden liquid fat. Here’s how it works:

1. Heating Butter or Cream

• Butter or cream is heated in the clarifier.
• The heat melts the fat and evaporates the water content.
• As the temperature rises, the milk solids begin to separate and either sink to the bottom or form a foam on the surface.

2. Separation of Milk Solids

• Milk solids (proteins and other impurities) are denser than the fat and settle at the bottom of the clarifier.
• Some solids, especially lighter impurities, may float to the surface as foam or scum.

3. Controlled Heating

• A clarifier is designed to provide consistent, controlled heating to prevent burning of the milk solids or the fat.
• The heating temperature is typically maintained between 100–120°C (212–248°F) to ensure the proper separation without burning.

4. Filtration or Skimming

• Once the milk solids and foam are separated, the liquid fat (ghee) is either:
  • Decanted: Carefully poured off, leaving the solids behind.
  • Filtered: Passed through a fine mesh or cloth to catch any remaining impurities.

5. Cooling and Storage

• The pure ghee is cooled and stored in containers.
• It solidifies at room temperature, forming a golden-yellow, aromatic product free of water and impurities.

Key Features of Ghee Clarifiers

• Industrial Clarifiers: Often equipped with automated stirring, temperature control, and filtration systems to handle large batches efficiently.
• Home-Scale Methods: Use a simple saucepan or kettle on a controlled flame, but the principle remains the same.

The resulting ghee is shelf-stable because it lacks water and milk solids, making it resistant to spoilage.
