After the vacuum packaging machine has created a low vacuum inside the packaging bag, the bag is automatically and immediately sealed. Thanks to the high vacuum in the bag and the minimal amount of residual air, the growth of bacteria and other microorganisms is inhibited, and oxidation, mold growth, and product damage are prevented. At the same time, the packaging volume of some soft products can be reduced after packaging by the fully automatic vacuum packaging machine, which is convenient for transport and storage. The principle of the desktop vacuum packaging machine is the use of plastic composite film or plastic-aluminum composite film as packaging material for vacuum packaging or vacuum filling of solid, liquid, powdered, and paste-likefoods, grains, fruits, pickles, preserved fruits, chemicals, electronic components, precision instruments, rare metals, etc.
Types of Vacuum Packaging Machines
It can be divided into desktop vacuum packaging machines, single-chamber vacuum packaging machines, double-chamber vacuum packaging machines, vertical vacuum packaging machines, household vacuum packaging machines, external vacuum packaging machines, and many other types of vacuum packaging machines.
Operating Process of a Vacuum Packaging Machine
Vacuum
The vacuum chamber closes, the vacuum pump starts running, the vacuum chamber begins to evacuate, the packaging bag is simultaneously evacuated, the vacuum gauge rises, and the desired vacuum level is reached (controlled by the ISJ time relay). The vacuum pump stops running and the vacuum is released. While the vacuum is active, the IDT two-position, three-way solenoid valve operates, the air chamber for hot sealing is evacuated, and the clamping frame remains in place.
Heat Seal
The IDT is disconnected, and outside air enters the heat-insulated air chamber through the upper air inlet.
Due to the pressure difference between the vacuum chamber and the heat-sealing air chamber, the heat-sealing air chamber is inflated, causing the upper heat-sealing frame to move downward and press against the opening of the bag. At the same time, the heat-sealing transformer activates and begins the sealing process.
At the same time, the 2SJ time relay activates; it trips after a few seconds, stopping the welding process.
Return flight
The 2DT two-way, two-position solenoid valve is open; atmospheric air flows into the vacuum chamber; the vacuum gauge needle returns to zero; the heat press frame is reset by the return spring; and the vacuum chamber opens.
Cycle
Move the vacuum chamber shown above to another vacuum chamber, and then proceed to the next step in the process. The left and right chambers operate alternately and cyclically.
Features of the Vacuum Packaging Machine
For liquid and high-viscosity materials, it can automatically form pouches and fill and package them with high precision and at high temperatures. (Compatible with external vacuum packaging machines)
Accept the extrusion-discharge packaging method. (In-house vacuum packaging machine)
The material has high corrosion resistance and fully complies with food hygiene and corrosion prevention requirements.
The main machine features a sturdy structure, a multilingual human-machine interface, and simple operation.
It can be optimally combined with various types of filling systems to achieve the best packaging results
Automatic Packaging Machine from LTC PACK
The LTC Pack vacuum packaging machine is equipped with intelligent computer control, ensuring high packaging speed, high precision, and minimal errors. The machine is made of stainless steel and does not contaminate the product upon contact. The machine can automatically perform tasks such as quantitative feeding, bag forming, filling, counting, sealing, cutting, dispensing finished products, labeling, printing, and other operations.
1. The packaging machine’s PLC control system features a user-friendly design and a high degree of automation. It includes self-alarm, automatic stop, and self-diagnostic functions, and is safe and easy to use, with quick maintenance.
2. The entire machine features a modular design and is highly versatile. It can serve as a single machine for multiple purposes by swapping out different dosing devices, which saves on costly plant investments.
3. Advanced PLC control system with a bilingual display in Chinese and English. The packaging speed and bag length can be continuously adjusted within a specified range without replacing any parts.
4. The paper rack is equipped with its own gravity-fed mechanism that compresses and feeds the paper. The feed length of the packaging paper has been doubled, and the bag is flat and has no sharp edges.
5. The packaging capacity, inner bag, outer bag, label, etc., can be customized as desired. The sizes of the inner and outer bags can be adjusted to meet users’ various needs in order to achieve the ideal packaging effect.
6. Operations: A series of operations—such as quantitative feeding, bag forming, filling, counting, sealing, cutting, and discharging finished products—are all performed automatically.
How to Improve Your Packaging
Install the machinee: First, install the machine and the packaging film; then, install the packaging paper on the bracket and try to align the edge of the packaging paper vertically and parallel to the central opening of the support frame.
Turn on the power: Install the device, lay it flat, connect the switch, and wait for the device to start working. The plug must be connected to the outlet using a grounding wire.
Set Parameters: Set the length of the packaging bag, the temperature parameters, and the weight of the material.
Pour the material: Pour the material into the hopper and press start.
Automatic packaging:The machine weighs, unloads, seals, cuts the bags, and forms the packaging all in one step.
