How to Pick the Right Oil Filling Machine
There are several considerations to be made while selecting an oil filling machine, like its speed and accuracy, the availability of space, your budget and so on. However, the most important criteria for any kind of oil packaging is the viscosity of that particular oil. Viscosity can be better understood as a liquid’s resistance to flow. A liquid with low viscosity shows low resistance, that is, it flows more easily than a liquid with high viscosity. Therefore, thicker liquids, like ghee are more viscous than thinner liquids, like coconut oil. The viscosity of the oil is relevant to determining the kind of oil filling machine because different types of fill mechanisms are available, depending on the flow of the liquid.
Over Flow Fillers Automatic Filling Machines with this kind of fillers work on the overflow principle. The liquid product is automatically filled into all the containers or pouches up to a certain specified level, irrespective of the slight variations in the internal volumes of the containers or pouches. The excess liquid overflows and is transported back into the supply tank. The overflow mechanism is especially useful when free-flowing liquids, like water, wine and olive oil need to be filled in transparent containers or pouches because it ensures an aesthetic shelf presence when they are neatly lined up next to each other.
Gravity Fillers These Liquid Filling Machines work on a time-and-gravity-based-system. The packets or pouches align under the tank containing the liquid product. The valves of the tank open automatically for a pre-set duration, allowing the liquid product to flow into the packets or pouches. These liquid filling machines are an economical option for packaging free-flowing liquids as they utilize gravity to assist in the filling process.
Pump Fillers For viscous liquids, like tomato puree or vanaspati ghee, that require an extra push as compared to free-flowing liquids, automatic filling machines with pump fillers of different kinds can be used. Pump Fillers use pumping force or pulse-based-rotation to push the viscous product into the packets or pouches. The type of pumping mechanism can be selected based on the specific attributes of the particular viscous liquid.
Piston Fillers Automatic Filling Machines with the piston and cylinder mechanism can be used for accurate volumetric filling of viscous liquids. These fillers work like a syringe, filling the pouches with a pre-determined volume of the viscous product, yielding an accurate volume of product in every pouch. These machines are particularly useful for products that contain chunks, like jams and salad dressings. Once you have determined what kind of filler is best suited for your product, you may consider other criteria, like speed, accuracy, space constraints, budget as well as the option of versatile pouch formats.
