Cottage Cheese Filling Machine for Curd Cups and Tubs
Fill small-curd, large-curd and fruit-on-bottom cottage cheese into pre-formed cups and tubs without crushing the curd. The SDH-R fills, membrane-seals and lids up to 30 cups per minute with ±0.5% servo-piston accuracy.
A cottage cheese filling machine doses creamed curd into pre-formed cups or tubs, then seals and lids them. Hummus Pack's SDH-R is a fully automatic rotary cottage cheese filling machine that uses a servo-driven volumetric piston with large-bore valving to protect curd, holds ±0.5% fill-weight accuracy from 50 g to 500 g, and runs up to 30 cups per minute (18–25 real-world) with optional fruit filling, nitrogen MAP and snap-on lids.

What a Cottage Cheese Filling Machine Has to Get Right
A cottage cheese filling machine meters creamed curd into pre-formed cups or tubs, seals each container and applies a lid, without crushing the curd or smearing dressing across the sealing flange. The product is a suspension of soft, elastic curd pieces in a thinner cream dressing, and a filler that treats it like a smooth paste delivers broken curd, uneven fill weights and leaking seals.
Our answer is the SDH-R automatic rotary cup filling, sealing and lidding machine, designed and built in Calgary, Alberta. In one pass on an indexing turret it denests cups, fills with a servo-driven volumetric piston, adds fruit or a topping from optional extra fillers, heat-seals a membrane from roll film, can flush with nitrogen, and places a plastic lid. As high-protein eating puts cottage cheese back on growth plans, it gives regional creameries, specialty brands and co-packers a compact way to automate without committing to a full high-speed dairy line.
Our overview of the rotary cup filling machine explains how a dial-indexing design compares with straight-through lines. The rest of this page covers what matters specifically for cottage cheese.
Curd Integrity: How a Curd Filling Machine Avoids Shear Damage
Curd definition is the first thing a shopper judges. Every point where curd is squeezed, accelerated or forced through a narrow opening breaks pieces apart, and the resulting fines cloud the dressing, release whey and make the product look mealy. Large-curd cottage cheese is the most sensitive, but small-curd product suffers too on an aggressive line.
Design choices that protect the curd
- Large-bore valving. The SDH-R's wide-bore valve options pass particulates such as nut pieces and shredded cucumber. For cottage cheese we size the bore to your largest curd, so pieces flow through instead of being pinched as the valve closes.
- Gentle piston strokes. Because the piston is servo-driven, stroke speed is set per recipe and stored on the HMI, slower for large curd and faster for a smooth small-curd blend.
- The right nozzle. A cut-off nozzle gives a clean break at the end of each deposit; a suck-back nozzle pulls dressing back so it does not drip onto the flange.
- Gentle product paths. Much curd damage happens upstream, in high-shear transfer pumps and long pipe runs. We review how dressed curd reaches the hopper as part of every quote.
Creamed Curd vs Dressing: Holding Fill Weight with Particulates
Creamed cottage cheese is two materials moving together: drained curd and a cream dressing blended at a target ratio. That ratio is what makes dosing harder than with a uniform paste. A volumetric piston measures volume precisely, and the SDH-R holds fill-weight accuracy of ±0.5% on a consistent product. When the blend drifts, density drifts with it, and so does weight.
Where fill weight goes wrong on cottage cheese lines
- Stratification. Left standing in the hopper, curd and dressing separate, so early cups run curd-heavy and late cups dressing-heavy. Smaller, frequent additions from a blended source keep the ratio steady.
- Syneresis and weeping. Curd keeps releasing whey. Product held too long before filling carries more free liquid, changing density and appearance.
- Temperature swings. Dressing viscosity changes with temperature, so product should arrive at a steady refrigerated temperature.
- Trapped air. Large curd can bridge in the cylinder and give a light deposit; slower intake strokes reduce this.
For tighter control, we offer a weight checker with a feedback loop to the filler, so drift is corrected rather than simply rejected. Our piston filling machine page explains volumetric dosing in depth. Dry (uncreamed) and low-fat curd follow the same rules; the leaner the dressing, the more bore size matters.
Cottage Cheese Tub Filling and Sealing, Station by Station
The SDH-R completes every operation in one pass on its rotary turret. For a cottage cheese cup with a membrane and over-cap, the sequence is:
- Cup loading. A pneumatic denester places a pre-formed round, square or rectangular cup in each pocket.
- Base fill. The servo-driven piston deposits dressed curd, or fruit first on fruit-on-bottom recipes.
- Secondary fill (optional). A second or third filler adds curd over fruit, a topping or a garnish.
- Membrane sealing. Roll film is heat-sealed to the flange as a tamper-evident closure.
- Nitrogen MAP flushing (optional). Residual oxygen is reduced.
- Lidding (optional). A plastic lid is placed by pick-and-place or the snapping device.
- Discharge. Cups exit on the conveyor toward coding, labeling and case packing.
Seal quality depends on a clean flange. Dressing can splash or string, and a film of cream under the membrane causes channel leaks that show up as soiled cases days later. The right nozzle keeps the flange dry; seal temperature, pressure and dwell are then set for your film and cup material and saved with each recipe. Our automatic cup sealing machine page covers membrane sealing in detail, and pre-die-cut lids are available instead of roll film.

Fruit cottage cheese is a multi-component fill, and the SDH-R carries up to three fillers on one machine. Each filler is matched to what it deposits:
- Fruit-on-bottom. A fruit preparation goes in first from a piston filler sized for its pieces, then curd from the next filler, set to sit on the fruit without driving it up the cup wall.
- Fruit-topped or drizzled. Curd fills first, then fruit syrups and sauces go on by peristaltic pump, or chunky fruit, nuts and seeds by the garnish filler.
- Savory cups. Seasoning blends go on with the vibration filler, and herbs or coarser toppings with the garnish filler.
Because every deposit happens on one indexing turret, layers stay consistent cup to cup without a second machine or a manual topping station. Each component's volume and stroke are stored together in the recipe. Our guide to multi-component filling for layered dips and parfaits covers layering strategy in depth.
Cottage Cheese Cup Filling Machine Formats: Snack Cups to 24 oz Tubs
Cottage cheese ships in two container families: single-serve snack cups of 4–5.3 oz and family tubs of 16 or 24 oz. As a cottage cheese cup filling machine, the SDH-R runs 4, 8, 10 and 16 oz cups on standard tooling and custom sizes from 2 to 32 oz with matching change parts. Its standard fill range of 50–500 g is the key number when planning a large tub.
Cottage cheese container formats on the SDH-R
| Cup format | Approx. fill weight | Notes |
|---|---|---|
| 4 oz single-serve cup | About 113 g | Standard tooling; well inside the 50–500 g fill range |
| 5.3 oz single-serve cup | About 150 g | Custom tooling within the 2–32 oz range; a common high-protein snack size |
| Fruit-on-bottom single-serve | Fruit plus curd to labeled total | Second filler for fruit; one recipe |
| 8 oz cup | About 227 g | Standard tooling |
| 10 oz cup | About 283 g | Standard tooling |
| 16 oz tub | About 454 g | Standard tooling; near the top of the standard fill range |
| 24 oz tub | About 680 g | Custom tooling; above the 500 g standard fill range, so filler sizing is engineered and confirmed before quoting |
Changeover between SKUs takes under about 15 minutes, with fill volume, stroke and seal settings recalled from the HMI recipe, so snack cups in the morning and tubs in the afternoon is practical. Real-world speed is 18–25 cups per minute depending on product, cup size, fill weight and options; heavier fills need longer strokes, so plan large-tub throughput conservatively.
MAP and Shelf Life in Cottage Cheese Packaging
Fresh cottage cheese is a short-shelf-life refrigerated product. Molds need oxygen and oxidized dressing develops off-flavors, so headspace oxygen matters. The optional nitrogen flush makes the SDH-R a cottage cheese packaging machine with MAP: residual oxygen drops to 0.3–0.4%. Across fresh refrigerated cups, that typically extends shelf life from roughly 7–10 days to 30–45+ days, product-dependent.
For cottage cheese, the gain depends on your culture, dressing, post-pasteurization hygiene and cold chain. MAP replaces none of those, and date codes should come from your own validated shelf-life studies. Our MAP cup filler page explains the gas-flush hardware, and our article on nitrogen flushing and refrigerated shelf life covers how producers test it.
Milk Allergen Control, Sanitation and CIP on a Dairy Cup Filler
Milk is one of the nine major US food allergens under FALCPA (sesame became the ninth on January 1, 2023, under the FASTER Act), and cottage cheese is a ready-to-eat food exposed to the plant environment between pasteurization and sealing. Both facts shape how a dairy cup filler is built and cleaned.
- Food-grade 304 stainless steel construction with FDA-compliant food-contact materials.
- Tool-free strip-down of product-contact parts for inspection and cleaning.
- Optional CIP (clean-in-place) for repeatable wet cleaning between shifts.
- Documented allergen changeovers when the machine also runs non-dairy products such as hummus or plant-based dips.
The SDH-R is designed to support plants operating under HACCP, BRCGS or SQF and the FDA FSMA Preventive Controls rule (21 CFR Part 117), where ready-to-eat producers verify sanitation, often through environmental monitoring for Listeria monocytogenes. It equally supports preventive control plans under Canada's Safe Food for Canadians Regulations (SFCR/CFIA), and EU customers can review food-contact documentation against Regulation (EC) 1935/2004 with us. The machine carries CE and UL listing with FDA-compliant materials; plant certification remains your own program.
When the SDH-R Fits, and When a High-Volume Dairy Line Is Better
We would rather tell you up front if our cottage cheese filling machine is the wrong choice. The SDH-R is built for fresh, refrigerated cups at 18–25 cups per minute in real production, roughly 1,080–1,500 cups an hour before planned downtime.
Where it fits
- Regional creameries and specialty brands adding cottage cheese cups to a cultured-dairy room
- High-protein brands running several flavors and fruit-on-bottom variants
- Co-packers filling cottage cheese alongside other cultured dairy, spreads and dips
- Plants moving off hand-filling, where curd damage and giveaway are costly
Where it does not
- Single-SKU volumes well above 30 cups per minute, which call for an inline or multi-lane dairy line
- Aseptic or shelf-stable dairy; the SDH-R is not an aseptic or retort system
- Frozen products, or cups you need to thermoform in-line; the SDH-R runs pre-formed cups
- Fills below 50 g, which sit outside the standard fill range
For volume beyond a single rotary machine, compare our inline cup filling machine options.

Cottage Cheese Filling Machine — Frequently Asked Questions
Hummus Pack's SDH-R cottage cheese filling machine starts from $45,000 USD in a single-filler configuration. Price rises with options such as a second filler for fruit-on-bottom cups, nitrogen MAP, plastic lidding, labeling, coding, a weight checker, CIP and custom tooling for 5.3 oz or 24 oz containers. A firm quote is based on your product, cup sizes and target cups per minute.
The SDH-R runs up to 30 cups per minute on a dry cycle and typically 18–25 cups per minute in real cottage cheese production, depending on curd size, cup size, fill weight and options such as fruit filling, MAP and lidding. That is roughly 1,080–1,500 cups per hour. Single-SKU operations needing well above 30 cups per minute suit an inline or multi-lane dairy line.
It can if the valve, nozzle and stroke are wrong, which is why the SDH-R is configured around your largest curd. Large-bore valving lets curd pass instead of being pinched, the servo-driven piston stroke can be slowed for large curd and saved as a recipe, and the nozzle is matched to your dressing. Upstream pumps and pipe runs should also be reviewed, since much curd damage happens before the filler.
The SDH-R's standard tooling covers 4, 8, 10 and 16 oz cups, and custom change parts cover containers from 2 to 32 oz in round, square or rectangular shapes. A 5.3 oz single-serve cup uses custom tooling. A 24 oz tub, about 680 g, also needs custom tooling and sits above the standard 50–500 g fill range, so our engineering team confirms filler sizing before quoting.
The SDH-R's servo-driven volumetric piston holds fill-weight accuracy of ±0.5% when the product entering the hopper is consistent. With cottage cheese, the main risk is the curd-to-dressing ratio drifting as product stratifies or weeps, which changes density. Feeding the hopper from a well-blended source at a steady refrigerated temperature keeps weights tight, and an optional weight checker with a feedback loop corrects drift automatically.
Yes. The SDH-R carries up to three fillers in one pass, so a fruit preparation can be deposited first with dressed curd added on top, or curd can be filled first with fruit sauce, chunky fruit or a garnish placed above it. Each filler is matched to its ingredient: a piston filler for fruit preps, a peristaltic pump for liquids and a garnish filler for fruit pieces, nuts or seeds.
It can help. The SDH-R's optional nitrogen flush reduces residual oxygen in the container to 0.3–0.4%, limiting oxygen-dependent spoilage such as mold. Across fresh refrigerated cup products, MAP typically extends shelf life from roughly 7–10 days to 30–45+ days, but results are product-dependent. Culture, dressing, hygiene and cold chain still drive cottage cheese shelf life, so validate dates with your own studies.
The SDH-R is built from food-grade 304 stainless steel with tool-free strip-down of product-contact parts and an optional clean-in-place (CIP) system. Milk is one of the nine major US allergens under FALCPA, so plants that also run non-dairy products such as hummus or plant-based dips should use a validated allergen changeover and cleaning procedure. The machine is designed to support HACCP, BRCGS, SQF and FSMA preventive controls programs.
The SDH-R is designed and built in Calgary, Alberta, Canada, and ships 8–12 weeks from order confirmation with a 12-month warranty. Support comes from our Alberta, New Jersey and California service centres. Send your product, cup sizes, target cups per minute and options through our contact page, and our team typically replies within about 24 hours.
