Nut Butter Cup Filling Machine
Fill the thickest, most viscous nut butters cleanly and accurately. The SDH-R's servo piston handles everything from smooth peanut butter to crunchy almond butter.
Nut butters are among the thickest, most viscous products the SDH-R packages. Almond butter, peanut butter, cashew butter, and emerging alternatives like sunflower seed butter and tahini all require significant filling force, anti-stringing nozzle design, and oil separation management. The SDH-R's servo-driven piston delivers the force needed for cold nut butters while the agitated hopper prevents oil from pooling during long production runs.
Engineered for High-Viscosity Fills
High-Force Servo Piston
The servo motor delivers consistent force for ultra-thick nut butters that would stall pneumatic fillers. No air pressure fluctuations — every cup gets the same fill weight.
Anti-Separation Hopper
Continuous paddle agitation prevents natural peanut and almond butters from separating into oil and paste during filling runs.
Clean Cut-Off Technology
Nozzle and piston retraction sequence engineered for clean product cut-off, preventing stringing between cups — a common nut butter filling challenge.
Allergen-Safe Changeover
Full CIP wash and tool-free disassembly for validated allergen changeover between tree nuts, peanuts, and seed-based products.

How the SDH-R Fills Nut Butters
Fully automatic process from empty cup to sealed product — no manual labour required
Cup Denesting
Empty cups are automatically separated from a nested stack and placed into the rotary table carriers. The pneumatic denester handles round, square, and rectangular cups from 2oz to 32oz — ideal for the standard nut butters cup formats your customers expect.
Servo-Driven Filling
The volumetric piston filler draws a precise dose of nut butters and dispenses it into the cup. Servo control adjusts stroke length and speed per recipe, maintaining ±0.5% fill-weight accuracy across production runs. The PLC stores recipes for quick changeovers between product variants.
Membrane Heat Sealing
Roll-stock film is drawn across the filled cup and heat-sealed to create a tamper-evident, airtight membrane. Sealing temperature, pressure, and dwell time are individually controlled to match your specific film and cup material combination.
Snap-On Lid (Optional)
A pick-and-place mechanism applies a consumer-friendly snap-on plastic lid over the membrane seal. This two-barrier system provides both tamper evidence and reclosability — the standard expected by grocery retailers and foodservice distributors.
MAP Nitrogen Flush (Optional)
Modified Atmosphere Packaging replaces oxygen in the headspace with food-grade nitrogen immediately before sealing. For nut butters, this typically extends refrigerated shelf life from 7–10 days to 30–45+ days — a requirement for most retail distribution channels.
