Vitamin Premix Packing Machine in Thailand

Client Profile: A Innovator in Precision Nutrition

This client operates at the high-tech end of the feed additive spectrum. Their formulations are complex, often including heat-sensitive vitamins (A, D, E, C), moisture-absorbing carriers like rice hulls or silica, and proprietary micro-encapsulated ingredients.

Their production environment is controlled, with low humidity and dedicated mixing rooms to protect product efficacy. While their micro-dosing, blending, and quality control labs were state-of-the-art, the final packaging step was a concerning gap.

It was the last point where human error or equipment inadequacy could compromise a whole batch. Therefore, replacing this single piece of equipment was a targeted, high-impact decision. This standalone hygienic automatic packing scale would be installed in a dedicated, climate-controlled packing room, serving as the final guarantor of weight accuracy and product purity before shipment to feed mills across Asia.

Stringent Operational Parameters for the Thai Market:

• Material Type: Ultra-fine, low-density vitamin premix powders and aquaculture nutrient packs. Materials are often fluffy, prone to dusting, and extremely sensitive to moisture, oxidation, and cross-contamination.
• Bag Specifications: They use small, high-value packaging. The primary focus is on 5kg and 10kg foil-lined, multi-wall bags with high barrier properties. The machine's 10-50kg range provided the flexibility to also handle their 25kg standard aquaculture packs.
• Sealing Method: Absolute product integrity is non-negotiable. They utilize an integrated heat sealing system for the inner foil liner, followed by sewing of the outer bag. The packing machine needed to deliver a perfectly filled, settled bag to this sealing station.
• Critical Needs: Full SS316L stainless steel construction on all product contact surfaces for superior corrosion resistance and cleanability. Unparalleled weighing accuracy to manage extremely high-cost ingredients. A feeding system designed for low-density, aerated powders that can "flood" or "bridge" in conventional systems.

The Hygienic Engineering Solution: DCS-50FB (SS316L) Packing Scale

For this application, standard stainless steel (SS304) was not enough. RICHI proposed a customized DCS-50FB model with SS316L stainless steel for all wetted parts, offering the highest level of corrosion resistance and sanitary assurance.

Technical Specifications for the Thai Vitamin Premix Specialist:

• Model Deployed: DCS-50FB Automatic Packing Scale with SS316L Upgrade
• Optimal Application: Packing of sensitive vitamin premixes, amino acids, and aquaculture nutrient packs.
• Feed Mechanism: Stainless steel screw feeder (auger) with a variable pitch design. This specialized auger is engineered to handle low-density, fluffy materials gently, de-aerating the powder as it conveys to prevent flooding and ensure a stable, accurate fill.
• Packing Speed: A controlled and consistent 6-7 bags per minute for 10kg bags. Speed was deliberately optimized for accuracy and gentle handling over raw output.
• Weighing Accuracy: Achieved exceptional static ≤ ±0.1% and dynamic ≤ ±0.2% accuracy, which is critical when the cost per gram of material is exceptionally high.
• Power Configuration: 1.5 + 0.55 + 0.37 kW.
• Hygienic Design: All product contact parts (hopper, screw, discharge) were crafted from polished SS316L stainless steel, offering superior resistance to chlorides and acidic compounds. Sanitary fittings, rounded corners, and quick-release clamps were included for rapid disassembly and cleaning.

Addressing the Demands of Advanced Asian Production

Installing a vitamin premix packing machine in Thailand meant meeting the standards of a world-leading aquaculture and livestock region:

• Humidity Control: Thailand's tropical climate is a challenge for hygroscopic vitamins. The enclosed, sealed design of the DCS-50FB system minimised the product's exposure to ambient humid air during the packing process.
• GMP and HACCP Compliance: The client's facilities are subject to stringent international audit standards. The machine's clean-in-place (CIP) capabilities, material traceability (all SS316L certificates provided), and lack of contamination traps were essential for compliance.
• Dust Containment for Operator Safety: Vitamin dust can be an irritant. The system featured integrated local exhaust ventilation (LEV) ports on the weighing hopper and bag spout to protect operators and recover valuable product.

Logistics: A Seamless Supply Chain to Southeast Asia

The vitamin premix packing machine was manufactured, pre-tested, and disassembled for shipping in sealed, desiccant-packed containers from Qingdao Port, China. The direct and high-frequency shipping route terminated at Laem Chabang Port, Thailand's largest and deepest seaport, located conveniently near the client's facility in Chonburi.

The RICHI Distinction: Specialization for Critical Applications

The client selected RICHI because we offered a bespoke solution, not a catalog item. The decision was based on technical specificity:

• Beyond Standard Stainless: While many suppliers offer "stainless," RICHI provided the option for SS316L, the correct grade for long-term resistance against the potentially corrosive nature of some vitamin carriers and mineral premixes, demonstrating true application knowledge.
• Advanced Powder Flow Management: The heart of this solution is the custom screw feeder. Our engineers designed a variable pitch and flight configuration based on the client's sample material characteristics, solving the classic problem of packing lightweight, non-free-flowing powders accurately—a key differentiator for premix packaging machinery.
• Accuracy as a Non-Negotiable Feature: The weighing system utilizes hermetically sealed, high-resolution load cells and RICHI's proprietary three-point anti-shock suspension. This system negates the influence of floor vibration and ensures that even the minute weights of dribble-feed are measured perfectly.
• A Service Partnership for Critical Operations: Our support package was designed for a zero-downtime mindset:
  • Joint development of a Site Acceptance Test (SAT) protocol prior to shipment.
  • Provision of 3D CAD models of the machine for integration planning into their clean room.
  • On-site installation and commissioning supervision by a RICHI engineer (included in the contract).
  • Training for maintenance staff on hygienic tear-down and re-assembly procedures.
  • A guaranteed spare parts holding program for critical components.

Direct Feedback from the Production Floor

After three months of running multiple, varied premix batches, the Operations Director reported: "Packaging our vitamin blends was our final quality hurdle. We couldn't risk contamination or inaccuracy. The RICHI stainless steel packing machine has been a revelation.

The SS316L gives us complete confidence during cleaning. The accuracy is phenomenal—we've verified it matches our lab scale. The custom auger handles our fluffiest vitamin ADE premixes without any flooding, which was a constant issue before.

It's not just fast; it's precise and clean. Having RICHI's engineer here for commissioning was invaluable; he tuned the PLC parameters perfectly for our materials. This machine has become a benchmark for reliability in our plant."

Setting a New Standard for Sensitive Product Packaging

The successful integration of this vitamin premix packing machine (stainless steel) in Thailand underscores a vital principle: for ultra-sensitive, high-value nutrients, packaging is a core component of product quality, not just a logistical step.

For this Asian industry leader, the customized DCS-50FB was a strategic investment in brand protection, customer trust, and manufacturing excellence. This case exemplifies RICHI Machinery's commitment to moving beyond standard solutions, providing engineered, hygienic systems that meet the exacting demands of the global animal nutrition industry.
