A canning machine, specifically can filling and seaming machines, also known as Can Fill and Seam Blocks, typically consist of two integrated packaging machines: a can filler and a can seamer. These canning machines can process a variety of products and can formats, and they are also equipped with product recovery and recirculation for hot filling. This ensures constant product temperature, even during downtime.
Our automatic canning machines, specifically our Fill and Seam Monoblock counter-pressure canning machines, are intelligently designed to provide precision rinsing, filling, and hermetic sealing to cans. They use double- or triple-seal processes to ensure airtight sealing.
Our can filling and seaming machines cater to a wide variety of applications and can be customized according to your production needs. Additional modules that make up our filling and seaming machines are available upon request, allowing us to meet specific production requirements, whether you are canning food preservation products or other industries like chemicals, cosmetics, or pharmaceuticals.
Different Types of Canning Machines
Measuring cups for free-flowing products:
Coffee (instant coffee, ground coffee), baking powder, breadcrumbs.
Multi-head weigher for mixed or single products:
Canned tuna, chicken, beef, pork, fish (salmon, sardines, mackerel), turkey, lamb, canned vegetables, soup mixes, and beans.
Liquids and paste pumps for liquids or viscous products:
Fruit juices (orange juice, apple juice), tomato paste, coconut milk, cooking oils (coconut oil, olive oil), beverage concentrates (fruit syrups, iced tea, cocktail mixes), broth and stock (chicken, beef, vegetable), condensed milk.
Auger screw for powders:
Milk powders (powdered milk), protein powders (whey protein, plant-based protein), soup mixes (instant soup powders, bouillons), cocoa powder, spices (garlic powder, chili powder), baby formula.
For products like fruits, vegetables, and meats that require additional liquids, a separate filling station must be added before the sealing process. Typically, cans are filled with both the product and the required liquid. This liquid is added after the product and before the can is sealed to ensure proper preservation and product quality.
Empty cans are individually fed into the filler station where a differential pressure chamber helps to carefully center each can in its optimal position to preserve container pressure.
After pre-flushing has taken place in a separate CO2 chamber with independent pressure adjustment, a pneumatic filling valve automatically lowers onto the cans and an inductive flow meter checks the quality and quantity of inflowing liquid.
The filling valve closes once the specified filling volume has been reached, whereafter the decompression process can begin.
Sensitive beverages that require hot filling utilizes a recirculation system to ensure consistent temperatures as the product is recollected in a special dedicated tank and recirculated into the processing system. In this system, the filler is cleaned and sanitized in a closed loop using false cans assembled under the filling valves and all internal areas in contact with the product are sanitized during the CIP.
Once cans are filled, they are conveyed by a discharge turret and chain towards the can seamer where a revolving lifter plate then raises each can up to the seaming rollers. Here, can lids, also known as ends comprising paper, tin, Aluminium, PET, plastic, or even glass are applied to the can body in three stages, namely compression, first roller operation, and second roller operation to ensure a reliable, airtight seam every time.
After the seaming operation has been completed, a cam-driven knockout pad releases the seamed cans from their respective chucks before they are conveyed down the line for final boxing and dispatching.
Once your cans are filled and sealed, you may need additional machinery to complete the packaging process. Options include:
Canning machines are versatile and can be used for a wide range of products, including:
A canning machine typically uses two main components: a can filler and a can seamer. The filler precisely measures and dispenses the product into the can, while the seamer seals the can tightly to ensure its contents are preserved. The process includes filling, sealing, and sometimes hot-filling or vacuum-sealing to maintain product quality.
A can filler fills the cans with the desired product, while a can seamer seals the cans by applying a lid (or end) and using rollers to ensure an airtight seal. The two machines work in tandem to ensure the proper packaging of products in cans.
For certain products like meats, vegetables, and fruits, additional liquids are required to ensure the contents are properly preserved. This liquid is typically added after the product itself and before the can is sealed. This process helps maintain the food’s quality, texture, and shelf life.
A Fill and Seam Monoblock machine combines the filling and sealing processes into one integrated unit. These machines are highly efficient, capable of filling cans with high precision and sealing them with airtight seals. They are ideal for high-volume production of canned goods.
Yes, most canning machines are flexible and can handle various can sizes. They come with features like automatic height adjustments, quick-change handling parts, and customizable settings to accommodate different can formats.
Our canning machines use low oxygen and CO2 consumption levels to maintain product quality. For sensitive products, like beverages, a recirculation system ensures that the product is kept at a consistent temperature during filling. Additionally, automatic cleaning (CIP) ensures that the machine is sanitized to prevent contamination.
Canning machines are used across a variety of industries, including:
Hot filling is a technique used to preserve beverages and food products by filling the can with a heated product. This helps to kill any bacteria and extend the shelf life of the product. Hot-filling canning machines often incorporate a recirculation system to ensure the product stays at a consistent, safe temperature during filling.
Some of the key benefits include:
Yes, canning machines can be easily integrated into most existing production lines. They are designed with high integration possibilities and can be connected with other machinery in your facility for streamlined production, including Shrink Tunnels, Labelling Machines, and Cartoning Machines to ensure comprehensive packaging solutions.
