quality Doypack Packaging Machine & VFFS Packaging Machine manufacturer

Butter, margarine, cream cheese, pastry cream, and chocolate spreads present unique packaging challenges: they are temperature-sensitive, require absolutely airtight seals to prevent oxidation, and demand precise fill weights for retail portion control. Our cream filling and sealing machine is designed specifically for cup filling and sealing machine applications, handling rigid containers from 10ml single-serve cups to 1000ml family-size tubs. It integrates volumetric or servo-piston filling with automatic foil or lid placement and heat sealing. Core technical specifications:     Parameter Value Fill accuracy ±0.3g (for 10-250g fills) Fill range 5ml to 1000ml Output speed 30-60 containers/min (depending on fill volume) Container types Preformed cups, tubs, jars, pots (round or rectangular) Sealing material Aluminum foil, pre-cut lidding film, roll stock Temperature control PID-controlled sealing plate (±1°C) Key engineering features for dairy applications: Temperature-controlled hopper and filling path: For heat-sensitive products like butter or cream cheese, our butter packaging equipment includes jacketed hoppers with circulating warm water (35-45°C) to maintain spreadable consistency without scorching. Servo-piston filling valve: Unlike gravity fillers that trap air, the servo-piston system pushes product with positive displacement, eliminating voids and ensuring ±0.3g fill accuracy even for viscous pastes like chocolate hazelnut spread. Vacuum-assisted sealing: Before the heat seal bar activates, a vacuum ring draws air out of the headspace, then back-flushes with nitrogen (optional). This airtight foil seal extends shelf life for dairy products from 2 weeks to 12 weeks. CIP-ready design: All product-contact surfaces are stainless steel 316L with no dead legs. The machine disassembles without tools for thorough cleaning – essential for dairy cup sealer applications requiring daily sanitation. Real customer case (European butter producer, 2025): A mid-sized dairy was hand-filling 250g butter tubs at 15 tubs/min with inconsistent weights (variance ±5g) and frequent leaker seals (8% rejection rate). After installing our automatic cup filler: Fill accuracy improved to ±0.3g, saving 120kg of butter per month in overfill Seal rejection rate dropped from 8% to 0.5% Output increased to 50 tubs/min Annual product savings alone: €18,000 Product applications for this paste filling machine:     Product Container type Typical fill volume Special consideration Butter / Margarine Tub, cup 125g, 250g, 500g Temperature control (soft but not melted) Cream cheese Cup, pot 200g Vacuum sealing to prevent oxidation Pastry cream Portion cup 25g, 50g No-drip nozzle for clean filling Chocolate spread Jar, tub 350g, 400g Piston filler handles inclusions (hazelnut pieces) Ghee / Clarified butter Jar 300ml Hot filling (70°C) compatible Whipped cream Canister (pre-sealed) 200ml Low-shear filling to preserve aeration Why June? June is peak production planning season for holiday baking products (Christmas butter and cream fillings require 4-6 months lead time). Additionally, summer ice cream toppings (chocolate sauce, caramel, fruit curds) in portion cups are ramping up for July-August peak consumption. Technical highlight – no-drip nozzle: One of the most frustrating issues with cream filling and sealing machine operation is product dripping between cycles, creating messy cup rims and failed seals. Our filling nozzles feature a spring-loaded shut-off valve that retracts upward after each fill, pulling any residual product back into the nozzle. The nozzle tip is heated to prevent product solidification at the outlet. Quality control integration: The cup filling and sealing machine can be integrated with: Inline checkweigher – rejects under/over filled cups automatically Leak tester – applies pressure or vacuum to each sealed cup to verify seal integrity Date coder – prints batch and expiry date on foil or lid Sealing material options: Aluminum foil (heat seal only) – standard for dairy, excellent oxygen barrier Pre-cut lidding film (peelable) – consumer-friendly for single-serve cups Roll stock lidding (PE/PP) – lower cost for high-volume production

For industrial-scale producers of construction chemicals, animal feed, fertilizer, or large-quantity food ingredients, standard VFFS machines struggle with heavy loads. Film drag, seal integrity under weight, and dust control become critical challenges above 10kg bag sizes. Our high speed vertical packaging machine is specifically engineered for large VFFS bagger applications, handling fill weights from 5kg to 20kg per bag at speeds up to 45 bags/min – significantly faster than traditional open-mouth bagging systems. Key engineering features:     Feature Benefit Reinforced film pulling belts Prevents slippage with heavy film rolls (up to 100kg roll weight) Servo-driven cross sealers with extra sealing pressure Ensures hermetic seals even with abrasive powders like cement or sand Dust extraction port integrated into forming tube Keeps sealing area clean for consistent seal strength Heavy-duty bag support platform Reduces film tension stress during the fill-and-drop cycle Real customer case (animal feed producer, 2025): A customer producing 500kg/hr of pelleted feed previously used an open-mouth auger filler with manual bag closing – 4 operators, 20 bags/min, frequent dust exposure issues. After switching to our high speed vertical packaging machine: Output increased to 45 bags/min (125% faster) Labor reduced from 4 operators to 1 operator Dust inhalation complaints dropped to zero Payback period: 11 months Bulk powder packaging equipment applications: Animal feed pellets (15kg, 20kg) Construction chemicals (cement, grout, plaster) Fertilizer and agricultural granules Large-quantity food ingredients (flour, sugar, rice, beans) Industrial resins and plastic pellets The machine supports bag widths from 350mm to 750mm and film types including PE, PP, laminated, and paper-plastic composites. The HMI stores up to 300 recipes, allowing quick changeover between different bag sizes and product types. Why June? Q3 is when many agricultural and construction supply chains begin stockpiling for autumn demand. Installing a high output packaging line now ensures you capture the July-September procurement cycle. Technical highlight – dust control: Unlike standard VFFS machines that allow dust to accumulate on sealing jaws, our industrial granule packer features a positive air flow system inside the forming tube, pushing dust downward into the bag rather than letting it drift upward. Sealing jaw temperature is monitored in real-time with closed-loop PID control, automatically compensating for any dust contamination that might reduce seal strength. Comparison with traditional open-mouth bagging:     Metric Open-mouth auger + manual close Our high speed VFFS Speed (bags/min) 12-20 40-45 Operators required 3-4 1 Dust exposure High Minimal (enclosed system) Seal consistency Operator-dependent Automated, ±1% variation Bag material cost Higher (requires sewn or glued closure) Standard heat-seal film

Summer heat accelerates food spoilage. For ready-to-eat meats, cheese, and prepared meals, standard vacuum packaging removes oxygen but doesn't replace it with a protective atmosphere. Our automatic vacuum packing machine is a dual chamber vacuum sealer with gas flush packaging capability (nitrogen or nitrogen+CO₂ mix). How it works: Bag placed in chamber Air evacuated (vacuum level adjustable from 50% to 99.9%) Nitrogen flushing system injects gas mixture Sealing bar closes (impulse or constant heat) Real shelf life extension data (tested with cooked chicken breast, 4°C storage):     Packaging method Shelf life (days) No vacuum 4 days Standard vacuum 7 days Vacuum + N₂ flush 21 days Vacuum + 70% N₂ / 30% CO₂ 30 days The dual-chamber design alternates cycles, achieving 3-5 cycles/min (depending on gas flush time). This cooked meat packaging solution is also ideal for ready meal vacuum packer applications. Who needs this now? Deli meat producers scaling up for summer BBQ season Ready-meal manufacturers supplying outdoor event caterers Cheese exporters requiring longer transit protection
