Turnkey Canned Food Production Line for Tin Cans and Glass Jars
Warlter supplies complete canned food production lines for factories that fill tin cans or glass jars. Every line is planned around your product, your container, your daily output and your floor plan. The machines then work as one system, not as separate purchases that must be matched later.
Xuzhou Warlter Packaging Products Co., Ltd. was established in 2014 and supplies glass jars, bottles and metal lids to global markets. We also build food retort machines and automatic capping machines. That means we understand the container, the closure and the sterilizer together, and not only the filling line.

What Is a Canned Food Production Line?
A canned food production line is a full set of machines that turns raw food into a sealed, shelf-stable product in a can or jar. It covers every stage, from washing the raw material to stacking the finished cartons on pallets.
The main goal is food safety and shelf life. Heat sterilization destroys microorganisms, and a tight seal stops new ones from getting in. A good line also protects taste, color and texture while it does this.
Most canning plants follow the same general order: wash and prepare the food, fill the container, seal it, sterilize it with heat, cool it, then label and pack it. The machines, speeds and settings change with the product and the container.
How Does a Canned Food Production Line Work?
Our canned corn line shows a typical flow. It has 13 steps, and each step has its own machine:
| Step | Machine | What it does |
|---|---|---|
| 1 | Empty can depalletizer | Unloads empty cans automatically with magnetic lifting |
| 2 | Can washer and dryer | Cleans tinplate cans with high-pressure steam, then dries them |
| 3 | Corn cleaning machine | Removes husk, silk and debris with a bubble wash system |
| 4 | Corn blanching machine | Pre-cooks the corn for the right texture |
| 5 | Cooling machine | Cools the corn quickly after blanching |
| 6 | Solid filling machine | Fills corn kernels into cans or jars with high accuracy |
| 7 | Liquid filling machine | Adds brine, water or sauce |
| 8 | Double seaming machine | Seals the cans airtight |
| 9 | Filled can washer and dryer | Cleans the outside of the filled and sealed cans |
| 10 | Retort sterilizer | Sterilizes cans in automated batches with magnetic handling |
| 11 | Labeling machine | Applies labels to round cans or bottles |
| 12 | Case packer | Packs the cans into cartons automatically |
| 13 | Palletizing robot | Stacks cartons on pallets for storage and shipping |
Other products change the preparation steps. Beans, vegetables and fruit may need soaking, peeling, slicing or a different filling medium. The rest of the line, from filling to palletizing, stays close to the same.
If you pack in glass jars, the can washer and seamer are replaced by jar washing and a capping machine. Our steam vacuum capping machine is one option for sealing jars and bottles under vacuum.
Main Machines in a Canned Food Production Line
A complete line groups its machines into five stages. This table shows what each stage contains and why it matters.
| Stage | Typical equipment | Purpose |
|---|---|---|
| Preparation | Cleaning machine, peeling and slicing machine, blancher, cooling machine | Gets the raw food clean, cut and pre-cooked |
| Filling | Solid filling machine, liquid filling machine, mixer | Puts the right weight of food and liquid in each container |
| Sealing | Double seaming machine for cans, capping machine for jars | Closes the container so it is airtight |
| Sterilization | Retort sterilizer, pasteurizer, heat exchanger | Heats the sealed product to make it shelf stable |
| Finishing | Labeling machine, case packer, palletizing robot, conveyors | Labels, packs and stacks the finished goods |
Some recipes also need extra machines, such as a mixer for sauces, a heat exchanger for hot filling, or a fryer for specific ingredients. We add only what your product needs.
Solid Filling Machine
This machine fills corn kernels or other solid food into tin cans and glass jars. It is built for accuracy, so every container carries a uniform weight.
Cleaning and Blanching Section
A bubble washer removes impurities from the raw material. Blanching then improves color and flavor and helps extend shelf life.
Retort Sterilizer
The retort is the key safety step. Ours uses automated loading and unloading with magnetic handling, and it can sterilize food packed in tin cans or glass jars. See our full range of food retort machines.
Filled Can Washer and Dryer
After filling and sealing, this machine removes residue from the outside of the can. The result is a clean, professional product before labeling.
Palletizing Robot
The robot stacks cartons at the end of the line. It cuts manual labor and reduces damage from handling.
Benefits of an Automated Canned Food Production Line
Moving from manual or semi-automatic work to a connected line brings clear gains:
Consistent quality. Every can or jar gets the same fill weight, seal and heat treatment.
Lower labor cost. Machines handle depalletizing, filling, packing and stacking.
Cleaner production. Stainless steel machines and closed handling reduce contact with the product.
Higher output. A linked line avoids the waiting and double handling between separate machines.
Less waste. Accurate filling and gentle handling protect the product and the containers.
Types of Canned Food Production Lines We Build
Canned Corn Production Line
Our canned corn production line runs the full 13-step flow shown above, from corn cleaning and blanching to filling, sterilization and palletizing. It is a good starting point if you pack whole kernel corn in cans or jars.
Canned Beans Production Line
Bean lines add soaking and cooking steps before filling. They also need accurate liquid filling for brine or sauce. We plan the preparation section around your bean type and recipe.
Canned Vegetable and Fruit Production Lines
Vegetables and fruit often need washing, peeling and slicing before filling. Fruit lines may fill with syrup or juice, while vegetable lines usually fill with brine. We select the machines to match the cut size and the fill medium.
Glass Jar Canning Lines
Glass jar lines use jar washing, jar filling and a capping machine in place of can washing and seaming. Because we also make glass jars and easy-open twist-off metal lids, we can help match the jar, the lid and the capper so they seal well together.
Tin Can vs Glass Jar Production Lines
Both container types can run on a Warlter line. They differ in a few key ways:
| Feature | Tin can line | Glass jar line |
|---|---|---|
| Container preparation | Can depalletizer, can washer and dryer | Jar washing, bottle washing machine |
| Closing method | Double seaming machine | Capping machine, with steam vacuum capping where needed |
| Strength | Strong and light | Heavier and breakable |
| Sterilization | Retort | Retort with careful temperature and pressure control to protect the glass |
| Handling | Suited to magnetic handling | Needs extra care to avoid chips and breakage |
| Product visibility | Hidden behind a label | Customers see the food |
The right choice depends on your market, your brand and your product. We can plan a line for either container, or a line that switches between the two.
How to Plan the Capacity of Your Line
The size of a canned food production line depends on several factors. Think about these before you ask for a quote:
Daily output. How many cans or jars you want to fill per shift.
Container size. A small can and a large can run at very different speeds.
Product type. Corn, beans, vegetables and fruit need different preparation time.
Shifts per day. More shifts can mean a smaller, cheaper line.
Sterilization time. The retort is often the slowest step, because each batch needs heating and cooling time. We size the number of retorts to match your filling speed.
Future growth. It is cheaper to leave space for another machine now than to rebuild later.
We confirm the final speed and layout in your quotation, based on your product and container.
Factory Requirements and Utilities
A new line needs the right services in your building. These are the main ones:
| Requirement | Details |
|---|---|
| Electricity | 220V or 380V, 3-phase |
| Steam and hot water | For can washing, blanching and sterilization, depending on the design |
| Water | For cleaning, cooling and washing |
| Compressed air | For machines with pneumatic parts |
| Drainage | For wash water and cooling water |
| Floor space | Planned and customized for your factory layout |
Exact utility use depends on your line design. We share these figures in the quotation so you can prepare your plant.
Food Safety and Process Validation
Canned food safety depends on the right heat treatment for each product. Low-acid foods such as corn and beans need especially careful sterilization, and rules differ from country to country.
A line gives you the equipment to control time, temperature and pressure. The heat process for your recipe should still be set and validated by a qualified food safety specialist, in line with the regulations in your market.
How to Choose a Canned Food Production Line
Use this checklist before you decide:
Define your product. Write down the food, cut style and filling medium.
Choose your container. Decide on tin cans, glass jars, or both.
Set your output target. Count containers per hour and per shift.
Check your utilities. Confirm power, steam, water and air at your site.
Measure your space. Share your floor plan so the line can be laid out properly.
Look at the materials. Food-contact parts should use stainless steel, such as 304 or 316.
Plan for sterilization. Make sure the retort size matches your filling speed.
Ask about support. Confirm installation, training, spare parts and overseas service.
A good supplier works through these points with you before recommending a line.
Customization and Factory Layout Design
No two canning factories are the same. Buildings differ in shape, ceiling height and utility connections. For that reason, the dimensions of our lines are customized for each project.
We design the line around your layout and your output goals. We discuss the flow of raw material in, finished pallets out, and the places where people and forklifts need to move.
If you already own some machines, such as a filler or a labeler, tell us. We can plan the new equipment to connect with them.
Installation and After-Sales Support
A canning line is a major investment, so support matters. Warlter has engineers available to service machinery overseas.
Installation, operator training, spare parts and maintenance can be discussed as part of your quotation. Tell us where your factory is and when you plan to start, and we will plan the schedule with you.
