- Gravity Fillers
- Volumetric Fillers
- Auger Fillers
Types of Sealing Techniques
- Heat Sealing
- Induction Sealing
- Ultrasonic Sealing
- Pressure Sealing
Applications in the Food Industry
The versatility of filling and sealing machines makes them indispensable in processing a diverse range of food products, including:
- Beverages: Used for packaging water, juice, milk, soda, and alcoholic drinks.
- Sauces and Condiments: Efficiently package ketchup, mayonnaise, and salad dressings.
- Dairy Products: Essential for filling yogurt, cream, and various cheeses.
- Snacks: Handles packaging of nuts, popcorn, and chips.
- Baked Goods: Used in sealing bread, cakes, and cookies.
- Ready-to-Eat Meals: Ideal for soups, stews, and curries.
- Pet Food: Packaged both dry kibble and wet food options.
Filling and Sealing Process Flow
Understanding the operation of filling and sealing machines involves several key stages:
Product Feeding: Product enters the machine through a hopper.
Container Feeding: Empty containers are loaded automatically or manually.
Filling: Controlled filling ensures precision using mechanisms like pistons or augers.
Sealing: Containers are sealed through various methods ensuring secure packaging.
Ejection: The final sealed containers are ejected for further processing, labeling, or shipping.
