Industrial Sack Filling Machine

Before we delve into the specifics of sack filling machines, it’s important to pay attention to certain key factors that many buyers overlook. After purchasing a machine, they often realize that it cannot meet their needs or lacks adequate speed for their production requirements. In many cases, they could have purchased a suitable machine at a lower cost with a few modifications.

First and foremost, you should consider what products you intend to package in the sacks and their structural characteristics. These products can be categorized into two types: powder and granules. Most products packaged in sacks are granulated, meaning they are larger than sugar granules and have a granular structure.

The next factor is the production volume. For instance, if your production is limited, such as a seasonal farmer looking to package chickpeas, there is no need to invest in an expensive machine. You can opt for simpler, more affordable machines to package your products. Finally, consider the type of product. If your product does not fall under food industries and hygiene is not a major concern, you can purchase tanks and many components in metal to reduce costs.

Types of Industrial Sack Filling Machines

The sack filling machines from Alborz Machine Karaj include two models. The first model is a single-weighing sack filling machine, which can be used for filling various types of sacks, cartons, or bags. It features a simple structure and does not have complex technology, making it very easy to operate. The second model is a semi-automatic sack filling machine, which offers higher weighing speed and is more suitable for large workshops or places that require continuous filling of sacks.

The semi-automatic sack filling machines, or dual-weighing machines, come equipped with a color display and smart weighing systems, allowing them to weigh and package your products with much higher precision. They can be used for filling various granulated products into sacks.

Analog Sack Filling Machine

One type of machine that can be very useful for small producers, allowing them to package their products at a low cost, is the analog sack filling machine. The first advantage of this machine is that it operates on single-phase electricity, meaning you do not need access to three-phase power to use it, making it easy to operate in small workshops. The dimensions of the machine are as follows: length 85 cm, width 75 cm, and height 100 cm, making it perfectly suitable for small environments.

The tank and other parts that come into contact with your product are made of stainless steel, which has high resistance to moisture. This makes it ideal for packaging various products in the food industry, as the stainless steel allows for easy cleaning of the machine’s tank. Since this machine is produced entirely in-house at Alborz Machine Karaj, you can order the tank in metal if needed, especially if your product does not fall under food industries, such as plant fertilizers.

This machine can easily package weights ranging from 2 to 50 kilograms, and you can use it for packaging various small granulated products in sacks, such as rice or different types of legumes and dried fruits. If you want to stitch the sacks closed, you can use a separate stitching machine, which must be purchased separately.

Semi-Automatic Sack Filling Machine

Another machine you can use for filling various granulated products into sacks is the semi-automatic dual-weighing sack filling machine, which offers a significantly higher weighing speed. This machine is equipped with two weighing units that, with the help of sensitive sensors, can accurately weigh your product and package it into sacks.

The operation of the dual-weighing sack filling machine works as follows: First, your product is transferred into the machine’s tank via an elevator. You can even connect the elevator to sensors so that it accurately detects how much product is in the tank, only activating when the product level is low to refill the tank.

Next, the product is transferred to the weighing units via special vibrating trays, and the machine measures the product's weight according to your specified target weight. Once the desired weight is reached, the machine alerts the operator with an alarm and light to position the sack under the machine's nozzle and use a pedal to initiate the transfer of the product. Upon pressing the pedal, clamps hold the sack securely in place while the product is transferred into it.

At the front of the machine, there is a conveyor belt that moves the filled sack to the sewing section, allowing you to easily stitch the sack closed using a sewing machine and prepare it for market. If needed, you can even use a film sealing machine to package your products in film instead of sacks, allowing for packaging up to 50 kilograms. This machine is larger than the single-weighing model and is available in both single-phase and three-phase versions, so you can choose based on your facilities.

It’s important to note that single-phase machines operate pneumatically, meaning you need to use an air compressor, as all the machine’s cylinders are pneumatic and operate on air pressure. However, in terms of power and packaging speed, there is no significant difference between mechanical and pneumatic machines.

The dimensions of this machine are as follows: length 180 cm, width 140 cm, and height 290 cm, requiring this amount of space for use. Note that the width measurement excludes the front conveyor, so if you need the conveyor, you should account for additional width. The conveyor can be custom-ordered based on your needs. This machine features intelligent PLC and HMI systems, providing you with a dynamic user interface.

Auxiliary Equipment for Sack Filling Machines

You can purchase sack filling machines with various auxiliary devices that can assist you in packaging sacks and displaying product information. Below are some of these devices. The first type includes elevators, which are produced based on your product type, including Z-type elevators, bucket elevators, and PVC belt elevators, all of which can easily transfer your product into the machine's tank.

Elevators are tailored to your product type, but it's worth noting that you can also use manual labor to transfer the product into the tank, although this will reduce your efficiency.

The next device is a sewing machine, which is used to stitch the tops of sacks with thread. With this machine, you can sew various types of jute and plastic sacks. If you want to package your product in plastic bags, you can use semi-automatic thermal sealing machines that are installed on the conveyor belt of the machine.

Another device is the jet printer, which is used for printing product specifications on sacks. However, keep in mind that this machine is designed for printing on plastic sacks. With the jet printer, you can print information such as expiration dates, production dates, and other specifications so that your customers are informed.
