According to the Filling Type

Volumetric Fertilizer Packaging Machine

There are three main types of volumetric fertilizer packaging machines which are discussed in detail below:

Gravity Fertilizer Packaging Machine

Gravity Fertilizer Packaging Machine

This type of volumetric fertilizer packaging machine is typically employed for filling free-flow liquid-based fertilizer. This machine has a simple construction consisting of a hopper, filling nozzles, and, conveyors. It is used for filling the exact volume in every fertilizer packaging container, for instance, bottles, buckets, and jerrycans.

Working Principle

It operates on the working principle of time-based gravity filling. First, time is programmed on the machine's PLC control system. Afterwards, containers are placed on the moving conveyors. When they reach the filling nozzles, the liquid fertilizers start flowing down from the hopper to the filling nozzles due to gravity. When pre-programmed time is touched, filling stops.

Pump Fertilizer Packaging Machine

Working Principle

A time-based and pulse-based filling is employed in the the pump fertilizer packaging machines. In time-based filling, time is set for pump rotation during each style. Pulse-based filling is defined as one rotation or half-rotation of a pump in each cycle.

Piston Fertilizer Packaging Machine

Piston Fertilizer Packaging Machine

This machine allows the manufacturers to load both thin and thick viscosity fertilizers in the packaging containers. It is one of the most commonly employed machines in the fertilizer packaging line for precise volumetric filling. The extent of the piston stroke in this machine controls the volume of every fill accomplished by the equipment.

Working Principle

When containers move under the filling nozzles, the rotary valves open and fertilizer from the hopper moves with the stroke of the piston to the cylinder. On the second stroke of the piston, the liquid is dispensed inside the filling nozzles from where it is fed inside the container.

Auger Fertilizer Packaging Machine

Auger Fertilizer Packaging Machine

This machine is widely employed machine for solid fertilizer packaging such as powders, tablets, and granules. It has one to two filling heads that allow high volume fertilizer packing. It features an auger filling device that measures and dispenses the correct amount of fertilizer in the containers. Servo-driven controls allow for consistency and repeatability in every fill.

Working Principle

It has a simple working concept in which fertilizer materials are loaded inside the containers with the rotation of auger. A bulk amount of fertilizer is packed into the hopper. Due to the auger drive, the auger device or screw rotates. Because of auger movement, the fertilizer feed travels down the funnel to the containers via filling nozzles.

Net-weigh Fertilizer Packaging Machine

It is the only machine that measures and fills fertilizer feed by weight rather than volume. It is particularly employed for packaging expensive and aggressive types of fertilizers. Load cells found under the conveyors aid in achieving a high rate of accuracy. It can be considered as the most evolved type of weighing scale.

Working Principle

The fertilizer feed flows from the hopper to the filling nozzle that gradually dispenses it into the packaging container. Load cells located underneath the container measure the amount of fertilizer being loaded inside containers. First load cells record the tare weight of the containers and then materials are fed by the laminar flow. Electronic cards control the measuring process in the load cells and generate feedback after every cycle.

5. What is the Purpose of a Degassing Valve in in Fertilizer Packaging?

Have you seen tiny holes in the fertilizer packaging? These are de-gassing valves, normally present on the upper side of the fertilizer pouch packaging. They are also known as pressure relief valves. De-gassing valve is a one-way valve meaning it allows gases to escape from the packaging but prevents the entry of gases inside the fertilizer packaging.

Chemical reactions are continuously occurring in the granular fertilizer and produce ammonia gas. The fertilizer packaging could burst due to pressure build-up because of ammonia accumulation. Due to the de-gassing valve, this gas goes outside of the packaging, creating sable inside pressure. This valve is very important in maintaining the quality and strength of fertilizer.

Moreover, it also protects fertilizer packaging from rupturing or deforming due to high pressure.  It increases the expiration date of the fertilizer and provides safety to packaging and handlers during transportation and retailing.

6.Why PE and PP manufactured Bags are Popular For Fertilizer Packaging?

Plastic Fertilizer Bags- Picture Courtesy: O3 Design

Traditionally, burlap sacks or woven cloth bags were used for transporting and storing fertilizer. The invention of plastic has led to the creation of durable and protective pouches for packaging fertilizers. There are diverse types of plastic bags for fertilizers but the two most common are- PE (Polyethylene) and PP (Polypropylene) bags.

PE bags are frequently used for fertilizer packing because of their significantly higher water-proof feature about 30%. Secondly, it comprises of anti-skid strip that offers stability upon stacking. Moreover, they are tough, long-lasting, and have puncture resistance.

PP tapes are interwoven together in two opposite directions to form PP bags. This feature increases the tensile strength of the PP bags. Moreover, due to interweaving, the air is easily circulated in the bag which decreases the chance of bag swelling. Also, these bags cost less to manufacture and, therefore, are popular among fertilizer brands.

7.Is there any Difference between Solid Fertilizer Packaging and Liquid Fertilizer Packaging?

Fertilizers come in both solid and liquid physical states but do you wonder if are there any differences in the packaging of both fertilizer types? The answer is yes, there are some significant differences in both these fertilizer packaging.

Solid fertilizer packaging is manufactured using tough materials that can accommodate the weight and granular nature of fertilizers. These include pouches and sacks. Liquid fertilizer packaging involves containers that are meant for packing liquids, for instance, bottles, jerry cans, and buckets.

Solid fertilizers are usually first taken out of packaging and then applied to soils. Liquid fertilizers packaging is directly attached to a hose for spraying soils. Solid fertilizer packaging is typically made with paper, woven fabrics, and plastics while liquid fertilizer packaging is generally made with glass, metals, and, plastics.

8.What is the Difference between an Open Pouch and vs Valve Pouch For Fertilizer Packaging?

Valve Fertilizer Bags- Picture Courtesy: Packaging of the world

Both type of pouches- open and valve- are regularly used for holding fertilizer; however, there are some major differences between these two pouches. Let’s discuss a few of the differences:

Feature	Open Pouch Fertilizer Packaging	Valve Pouch Fertilizer Packaging
Opening	In this type of fertilizer pouch, the opening is found across the upper side of the pouch.	It has an opening for filling fertilizers in one corner.
Sealing	Sewing, heat sealing, and gluing paper tapes are used for closing the said pouches.	Ultrasonic sealing is employed for closing this fertilizer pouch.
Size Options	It has a variety of size options and can be small to large.	It has a limited size range like in between small and medium.
Price	Open-mouth pouches are less expensive to produce.	Due to its typical design, it is more expensive.
Air Permeability	It is more airtightly sealed to prevent air entry.	It is troublesome to hermetically seal valve pouches.
Stackability	They form loose pallets.	They form more tight pallets due to their better stackability.

9.What Do Numbers on Fertilizer Bag Packaging Mean?

Numbers on Fertilizer Bag- Picture Courtesy: Hobby Farms

The labels on fertilizer packaging have three striking numbers such as 20, 20, 20 or 21, 0, 0. The first number corresponds to the quantity of nitrogen in the fertilizer, the second number indicates the amount of phosphorus or more specifically phosphate (P₂O₅), and the third number shows the quantity of potash (K₂O) or potassium.

If there is 20, 20, 20 on the fertilizer packaging, it means that this fertilizer has an equal quantity of nitrogen, phosphorus, and potassium which is 20%. However, if the label says 21, 0, 0, it denotes that there is only 21% of the nitrogen in the fertilizer with no phosphorus and potassium contents.

10.How Long Does Fertilizer Packaging Last?

Shelf-life of Fertilizer Packaging- Picture Courtesy: Package Inspiration

Farmers and other consumers worry about the expiry date of their fertilizer packaging. Here is good news for you. Fertilizer packaging has no finite expiry date.

Unopened, fully sealed fertilizer packaging can last for several years. Liquid fertilizer in the packaging can have an expiry date of over 10 years if stored at a place with a temperature of below 37.7° C or 100°F, while granular fertilizer in the packaging has a longer expiry date than its liquid counterparts. If properly stored in a cool and dry place away from chemicals it can last for a couple of decades. However, organic fertilizer typically has a shelf-life of 1-5 years in tightly closed packaging.

However, if the packaging of granular fertilizer is opened then it should be stored away from humid areas as granules will quickly absorb water vapours, leading to their caking. Thus, it can lose its effectiveness and strength.

Conclusion

Fertilizer packaging is the one thing that holds, protects, distributes, and brands the fertilizer products.
