Jam is a condiment. It is usually made from pressed fruit, sugar, and sometimes pectin. Most jams are cooked. After making, jam is normally put into an airtight jar. Usually a jam contains as much sugar as it contains fruit. The two parts are then cooked together to form a gel.
When you are bottling jam there are several types of filling machines you may choose.
VKPAK designs and builds filling machines and packaging equipment for jam.
Our jam liquid filling machines are designed to meet the changing needs of the jam industry. We manufacture the ideal machinery to handle your jam filling needs and meet your production goals.
Jam refers to a product made of whole fruit cut into pieces or crushed, then heated with water and sugar until it reaches "jelling" or "setting" point, achieved through the action of natural or added pectin, then sealed in containers.
Recipes without added pectin use the natural pectin in the fruit to set. Tart apples, sour blackberries, cranberries, currants, gooseberries, Concord grapes, soft plums, and quinces work well in recipes without added pectin.
Other fruits, such as apricots, blueberries, cherries, peaches, pineapple, raspberries, rhubarb, and strawberries are low in pectin. In order to set, or gel, they must be combined with one of the higher pectin fruits or used with commercially produced or homemade pectin. Use of added pectin decreases cooking time.[From Wiki]
Alimentary products, especially products highly concentrated with sugar, have to be prepared and packaged with particular attention. Besides that, machines have to be resistant and made of high quality materials. Our machines are the right equipment to fill, cap, and label glass jars or plastic bottles containing jam or marmalade. Even jam or marmalade still containing pieces of fruit, or those in need of a hot-fill process can be filled with our bottling machines.
Jam has a high viscosity like other sauces such as peanut butter, VKPAK recommends the use of piston filling machines or rotary lobe pump filling machine.
1. It adopt the piston type metering pump to filling; the pump structure using quick-connect disassembly mechanism, easy to clean and disinfect;
2. Piston type metering pump piston rings made of tetrafluoroethylene;
3. PLC control system, frequency control, full automation;
4. It is easy to adjust the filling amount, can be slightly adjusted for each metering pump; easy to operate, fast adjustment;
5. With agitate in the tank, it will stir the material clockwise and counterclockwise direction;
6. Filling cylinder adopts rotary valve type piston pump to effectively prevent wire drawing and drip;
7. To ensure the bottles and filling nozzles are in the correct position, we add a special bottles position device to make the whole filling process smooth and stable. No bottle no filling.
8. The feed tank adopts double-jacket hopper with stirring

Container Cleaning Equipment
When dealing with food products, container cleaning equipment becomes very important as a means to protect the product from contamination. Rinsing machines for jars or other containers can be used to remove dust and debris from the containers prior to filling, removing the possibility of producing contaminated products or reducing the shelf life of a batch. Different container cleaning machines exist that allow the use of clean air, water or other cleaning solution to be used for the rinsing process.
Jam Filling Machines
Filling machines for jams, jellies and similar products will normally consist of either a pump filling machine or a piston filler. These fillers are better equiped for thicker products and products with particulates such as seeds or even chunks of fruit. Extremely thick jams may simply be to viscous to flow through a filling machine. In these cases, the jam or jelly can often be heated to achieve a more liquid, less viscous product that can be run through the machine. Of course, the entire product pathway, from the supply tank, through the tubes and down to the fill nozzles, must be kept at a constant temperature to ensure that the product flows evenly and the fill can be consistently and reliably repeated.
The other issue with filling jam and jelly type products comes when particulates are introduced into the product. These particulates may be seeds from strawberries or chucks of strawberries, apricots, apples or various other food products. The particulates have a tendency to settle on the bottom of the supply tank or product supply when introduced to the filling machine. This settling still results in the filling of containers, but without the particulates or products that are meant to be included. Product agitators can be added to supply tanks to constantly stir product and keep these particulates from settling, thus allowing the filling machine to pull both product and particulate from the tank.
Capping Machines And Cooling Conveyors
The type of capping machine used for jams and jellies will depend on the type of container and cap used to package the products. In all honesty, once past the filling portion of the packaging system, jams and jellies will often be capped, labeled and otherwise packaged without special considerations. However, if dealing with a heated fill to increase the flow of the product, it may be necessary to include a cooling conveyor between the filling equipment and the capping machine. A cooling conveyor may take many different forms, from a multi-tiered serpentine conveyor to a simple extended conveyor. These conveyor systems allow the product to cool before moving to the capping machine, ensuring that the cap is applied correctly and consistently without worrying about product or container expansion and damage after capping a heated product. Otherwise, spindle cappers, chuck cappers or even snap capping machines may be used to seal containers of jams, jellies and other similar products.
Like the capping machines, labeling machinery for jams and jellies will probably not require any special modifications. Labeling machines are available to apply labels on the front of containers, the front and back of containers, wrapped around containers or just about any other configuration necessary. Again, the only concern would be with heated products. Containers should be cooled before applying the label to avoid wrinkles or the peeling off of the label.
Again, like any other product, jams and jellies can present unique issues when using automatic packaging machinery. These issues are easily handled by choosing the correct packaging equipment to handle the unique charactieristics of these products.
