Cream Cheese Filling Machine

Cream cheese is one of the most difficult products in a dairy plant to portion cleanly. It is stiff, it is tacky, and its viscosity is strongly temperature dependent - a few degrees of drift between the blender and the nozzle changes how it flows, how it cuts off and how it sits in the cup. A cream cheese filling machine that ignores that will give you three different fill weights before lunch.

The SDH-R meters with a servo-driven volumetric piston sized for high-viscosity product. The piston displaces a fixed volume rather than relying on gravity or head pressure, so a product that will not flow on its own still lands within +/-0.5% of target anywhere from 50g to 500g. Stroke speed, dwell and nozzle open and close timing are all servo-controlled, which is what makes stiff product behave predictably.

Cut-off, stringing and surface finish

Tacky product does not stop when the piston stops. Left uncontrolled it draws a tail, and that tail lands on the cup rim - exactly where the membrane has to seal. The SDH-R applies a programmed suck-back at the end of the stroke: the piston retracts a set amount, the strand breaks cleanly, and the nozzle lifts away from a level surface instead of dragging through it. A clean flange means a reliable tamper-evident seal and a first-pass yield you can plan around, and a level fill means the shopper sees a flat, unbroken face when the lid comes off.

Fill temperature belongs in the recipe, not in an operator's head. The PLC and HMI store target fill temperature alongside piston speed, seal temperature, pressure and dwell for every SKU, so a whipped spread and a block-style base recall as two different, fully repeatable machines.

Cream cheese clings. It coats a cylinder wall, it packs into a nozzle shoulder, and any inclusion you add - fruit pieces, herbs, peppers - gives residue somewhere to hide. Sanitation on an automatic cream cheese filling machine has to be quick enough that operators actually complete it at the end of every run, not only before an audit.

Every product-contact surface on the SDH-R is food-grade 304 stainless steel. A clean-in-place circuit lets caustic and sanitiser recirculate through hopper, cylinder, manifold and nozzles without breaking the machine down, and when a full teardown is required the product path strips tool-free - no wrenches, no captive hardware, no parts that only the maintenance lead knows how to reassemble. Sanitary geometry matters more here than on a thin product, because a stiff spread will bridge across any ledge or dead leg you leave it.

Allergen and audit control

• Dairy and inclusion allergens: a documented wet clean plus visual teardown supports a changeover you can defend to a third-party auditor.
• Recipe records: the PLC and HMI hold fill volume, fill temperature and seal parameters per SKU, so lot settings can be reproduced or reviewed later.
• Certification: CE, FDA and UL certified out of the crate, which removes a common delay during line commissioning.
• Changeover time: format and recipe changes typically complete in under 15 minutes, so short runs of seasonal flavours stay economic.

The machine is designed and built in Calgary, Alberta by Alter Pack and carries a 12-month warranty, with service centres in Alberta, New Jersey and California. When a spread line goes down, the distance between your plant and a spare part matters more than any line on a spec sheet, and support comes from the engineers who built the frame rather than a reseller.
