For feed additive manufacturers, the physical stability and chemical indicators of products are equally important. Problems such as enzyme deactivation caused by moisture, deterioration of probiotics due to oxygen absorption, and caking of amino acids from moisture absorption usually stem not from the formula, but from the final packaging process. After 27 years of technological iteration, Marchi Packaging Equipment provides highly reliable packaging solutions for the industry from two dimensions: sealing technology and dust removal control.

I. In-depth Analysis of Equipment Hardware Configuration and Process Details
The MCZD-25F automatic feed additive packaging machine pursues outstanding metering performance, and prevents product quality deterioration in every detail of material circulation. The feeding system of the unit adopts vertical screw feeding, and the single screw is driven by a servo motor. For materials with different bulk densities such as fish meal, peptide enzymes, lactose and high-protein whey powder, stepless speed regulation feeding is realized by adjusting the screw speed and filling coefficient.
The bag loading system of the equipment consists of a bag storage bin, bag picking and sorting device, bag loading manipulator, bag clamping and discharging device, bag pushing device, bag mouth guiding device and vacuum system. In terms of bag mouth treatment, the equipment adopts an original linkage design of bag mouth guiding and dust removal: when the filling rod exits the bag mouth, the negative pressure dust removal device automatically starts to suck away powder adhered to the sealing area of the bag mouth, ensuring that air tightness will not decrease due to clamped powder during heat sealing and stitching.
II. Detailed Control of Sealing and Moisture-proof Process
The biggest worry in feed additive packaging is poor sealing and moisture-induced caking. Marchi equipment has carried out targeted optimization on the integrated automatic heat sealing and stitching machine. The built-in temperature controller of the equipment can automatically adjust the heat sealing temperature and stitching pitch according to the thickness of packaging materials such as kraft paper laminated bags, woven bags and plastic bags. After filling, the bag mouth clamping device flattens the bag mouth, then the heating block fuses the inner layer of the bag mouth, followed by knurling rollers to press lines to enhance tensile strength, and finally the stitching head carries out mechanical stitching reinforcement. This dual guarantee of heat sealing plus stitching can effectively block water vapor intrusion even in humid environments.
III. Restoration of Full-process Operation Scenarios
The hygiene standards in veterinary drug and premix production workshops are extremely strict. The whole MCZD-25F production line adopts a closed design with dust-proof covers from the feeding port to the finished product outlet. During operation, operators only need to select the formula parameters of "veterinary probiotics" on the touch screen, and the equipment automatically calls the corresponding screw speed and sealing temperature. The automatic bag picking, sorting, opening and loading manipulator sleeves the bag onto the discharging nozzle; the discharging nozzle extends to the bottom of the bag and moves upward slowly as materials are filled, which greatly reduces dust emission and improves bag filling density; after filling, automatic bag mouth dust removal is carried out, followed by heat sealing and stitching; after the finished bags are flattened and shaped by the bag inverting mechanism, they are grabbed and stacked by the high-level robotic palletizer with neat stacking patterns.
IV. Solutions to Core Pain Points
Pain Point 1: Thermosensitive materials such as enzyme preparations and probiotics lose activity due to high temperature during sealingSolution: Low-temperature heat sealing technology is adopted. On the premise of not damaging packaging materials, the heat sealing temperature is appropriately reduced and the heat sealing time is extended, which not only ensures the sealing effect, but also avoids high temperature conduction to the materials inside the bags and protects the biological activity of thermosensitive additives.
Pain Point 2: Powders such as copper sulfate and zinc oxide are prone to bridging at the bag mouth leading to material leakageSolution: A vibration device is installed at the end of the discharging section to make materials settle quickly through high-frequency micro-vibration. Meanwhile, an accurate bag mouth dust suction nozzle is equipped to ensure the bag mouth is completely clean before sealing, completely eliminating customer complaints caused by clamped powder and material leakage.
Pain Point 3: The floor of the packaging workshop is always covered with dust, making it difficult to pass environmental protection inspectionsSolution: The whole production line adopts a fully closed negative pressure dust removal system. Dust suction points are set at the equipment feeding port, discharging port and bag mouth cleaning position to directly recycle dust to the central dust removal system, and the cleanliness of the workshop environment meets the industry's environmental acceptance standards.
