type: concept tags: [manufacturing, ice-cream, procurement, equipment, scale-up, procedure] created: 2026-05-03 source: raw/markdown/2026-05-03-ice-cream-manufacturing-report.md source_image: raw/markdown/2026-05-03-ice-cream-phase2-diagram.png
Ice Cream Manufacturing Equipment Procurement Plan
Product: 14 oz retail ice cream tubs Strategy: Phased scale-up with equipment redundancy — older equipment transitions to backup, R&D, allergen, or specialty roles rather than being replaced.
⚠️ Scope Note — Phase Definitions
This plan has been restructured. Phase 1 is white-labeling (co-packer sourced product, own branding, sales testing). In-house manufacturing begins at Phase 2 (500 tubs/day). The old "aspirational" reference diagram (3,000–6,000 14 oz pints/day) has been promoted to Phase 4 (50,000 14 oz pints/month, ~2,273 14 oz pints/day).
Phase Summary
| Phase | Activity | Daily Output | Monthly Output | |
|---|---|---|---|---|
| Phase 1 | White-labeling / sales testing | 0 (sourced) | 5,000–10,000 units | |
| Phase 2 | In-house manufacturing start | 500 tubs/day | 10,000–15,000 units | |
| Phase 3 | Scale-up | 1,000 tubs/day | 20,000–25,000 units | |
| Phase 4 | Regional plant | ~2,273 14 oz pints/day | 50,000 14 oz units |
The old Phase 1 (250 tubs/day in-house) has been eliminated. Manufacturing now starts at 500 tubs/day with a 60-gallon pasteurizer as the first production vat. The 30-gallon pasteurizer is eliminated from the main path but may be added in Phase 2 for R&D/allergen work if needed.
See the "Reference Diagram Transcription (now Phase 4 foundation)" section at the end for full details.
Production Math
| Phase | Tubs/Day | Finished Gallons | Mix Needed | |
|---|---|---|---|---|
| Phase 1 | 0 (co-packer sourced) | — | — | |
| Phase 2 | 500 | ~55 gal | ~27–30 gal | |
| Phase 3 | 1,000 | ~109 gal | ~55–61 gal | |
| Phase 4 | ~2,273 | ~248 gal | ~124–140 gal |
Uses premium overrun assumptions: 35% for ice cream and 20% for sorbet. 14 oz tub = ~0.1094 gal finished product. Phase 4 calculation: 50,000 14 oz units/mo ÷ 22 production days = ~2,273 14 oz pints/day.
Cold Ingredient Inventory Planning
Weekly consumption (4-day rotation + Friday flex)
| Day | Base type | Refrigerated needed | Frozen needed |
|---|---|---|---|
| Monday | Dairy SKU #1 | ~85 lb | ~15 lb (inclusions) |
| Tuesday | Dairy SKU #2 | ~85 lb | ~15 lb (inclusions) |
| Wednesday | Sorbet SKU #3 | — | ~51 lb |
| Thursday | Sorbet SKU #4 | — | ~51 lb |
| Friday | Flex | Variable | Variable |
Weekly total: ~170 lb refrigerated dairy + ~132 lb frozen
Ideal par levels (2 deliveries/week — Mon/Thu)
| Category | Par level | Rationale |
|---|---|---|
| Refrigerated dairy (cream, whole milk) | 250–300 lb (3–4 production days) | Covers Mon–Thu dairy runs + Friday flex + 1-day safety buffer. Shelf life 5–7 days from delivery — stocking deeper risks spoilage. |
| Frozen fruit puree | 150–200 lb (3–4 sorbet days) | Frozen is shelf-stable for months, but fruit puree quality degrades after 4–6 weeks even frozen. Carry 3–4 production days to avoid weekly ordering overhead. |
| Frozen inclusions (mochi, brownie, marshmallow) | 80–120 lb (2 weeks) | Shelf-stable frozen. Order every 2 weeks — volume is small enough that weekly deliveries may not meet supplier minimums. |
Reorder triggers
| Ingredient | Reorder when below | Approx. weight |
|---|---|---|
| Cream | 2 days remaining (~16–20 gal) | ~135–170 lb |
| Whole milk | 2 days remaining (~8–10 gal) | ~68–86 lb |
| Fruit puree | 3 days remaining (~36–48 lb) | Count containers |
| Frozen inclusions | 1 week remaining (~40–60 lb) | Count cases |
Rule: Always reorder before the last production day using that ingredient. If dairy runs Mon/Tue, reorder by Friday. If the supplier misses Monday, Tuesday's backup stock absorbs the hit and Friday flex can recover.
Storage equipment sizing
| Unit | Par load | Cu ft needed | Recommended model |
|---|---|---|---|
| Reach-in refrigerator | 250–300 lb dairy (jugs/cartons, shelved) | ~22–27 cu ft | True T-23-HC (27 cu ft) |
| Chest freezer | 250–350 lb frozen (boxes/bags, stacked) | ~20–23 cu ft | True T-23F-HC or Arctic Air AFC20SC (20–23 cu ft) |
Phase 1 Procurement — White-Labeling / Sales Testing
Target: Validate product-market fit and build retail relationships before investing in manufacturing equipment. Duration: Until 3+ retail accounts are signed and sales velocity justifies in-house production. Budget envelope: $5K–$25K
What Is White-Labeling?
Source finished 14 oz ice cream tubs from a co-packer or wholesale supplier. Apply your own branding (pre-printed tubs or branded labels/sleeves). Sell through wholesale and retail channels. No in-house pasteurization, mixing, or freezing.

Sourcing Model
- Identify 2–3 co-packers or finished-product suppliers (Hawaii or West Coast).
- Negotiate MOQ, lead times, shelf life, and freight terms (dry ice / refrigerated).
- Verify supplier holds appropriate food safety certifications.
- Consider starting with 2 dairy SKUs and 2 sorbet SKUs from your planned lineup.
Storage Requirements
- Frozen storage for 1–2 weeks of inventory (~500–1,000 tubs at any time).
- Separate storage for dairy and sorbet if cross-contamination is a concern.
Exit Triggers (Phase 1 → Phase 2)
All of the following should be met before transitioning to in-house manufacturing:
- 3+ retail accounts signed with purchase commitments.
- Consistent weekly velocity >250 tubs/week for 4+ consecutive weeks.
- Customer feedback validates the 4-SKU lineup (A/B/C/D).
- Cash flow supports $150K+ equipment capex and facility buildout.
- Facility secured — at least 1,500 sq ft with utilities, drains, and permitting path.

Pasteurizer installed range: ~$45K–$70K+## Phase 2 Procurement — 500 Tubs/Day
Target: Semi-automated, redundant production. 3–4 people. Budget envelope: $150K–$350K+ (equipment only)
Phase 2 Batch Freezer Setup
Primary freezer: 1 × SaniServ B-10 (~10 qt / 2.5 gal finished per batch). Acceptable alternate: 2 × CB-350-class freezers. One CB-350-class freezer alone is undersized.
Redundancy is intentionally limited at this phase. If the main freezer fails, production stops unless the alternate freezer configuration was purchased. The business is protected by:
- Co-packer / white-label supplier relationship as emergency overflow
- Rapid repair / replacement plan (identify local service tech)
- Critical freezer spares (seals, blades, o-rings, lubricant, scraper parts)
Phase 2 Total Equipment: ~$150K–$350K+
Phase 2 Critical Spares
- Batch freezer: seals, blades, o-rings, lubricant, scraper parts
- Piston fillers: o-rings, gaskets, nozzle parts, seals, food-grade lubricant
- Air compressor / inclusion station: filters, drain parts, backup hose/fittings
- Aging tanks: gaskets, valves, clamps, agitator parts
- Blast freezer: door gasket, temp probes, fan guards
- Pumps: pump seals, impeller/rotor parts, hoses, clamps
- Coder: ink cartridges, batteries, cleaning wipes
- Sanitation: brushes, hoses, spray nozzles, sanitizer strips
- Packaging: extra tubs, lids, labels, cases
Phase 2 Redundancy Level
| Area | Level | Backup Plan | |
|---|---|---|---|
| Pasteurization | Medium | ||
| Batch freezing | Low–Medium | ||
| Filling | Medium | ||
| Coding | Medium | ||
| Labeling | High | ||
| Hardening | Medium | ||
| Frozen storage | Medium |
Goal: Phase 2 has no inherited Phase 1 production equipment. If one major machine fails, maintain partial continuity via emergency sourcing, manual fallback where possible, rapid repair, and critical spares.

| QA / lab station | Bench scale, temp probes, refractometer, pH meter | 1 set | $2K–$5K | In-line quality checks |
Total installed range: ~$400K–$900K+
Continuous Freezer Evaluation (Phase 4 Decision)
At 2,273 14 oz pints/day, batch freezers become a labor and throughput bottleneck. Evaluate:
| Factor | Batch Freezers (2–3×) | Continuous Freezer (Scrape-Surface Barrel) |
|---|---|---|
| Capital cost | $30K–$75K | $100K–$250K+ |
| Labor per shift | Higher (load/unload batches) | Lower (continuous feed) |
| Throughput | 15–30 gal/hr each | 100–500+ gal/hr |
| Overrun control | Batch-level | Continuous, requires tuning |
| Flavor flexibility | Easy (switch batches) | Harder (requires CIP between flavors) |
| Maintenance | Lower | Higher (scraper blades, seals, barrel wear) |
| Learning curve | Moderate | Steep |
| Best for | 4+ SKUs, frequent changeovers | High volume, few SKUs, long runs |
Recommendation for Phase 4: Start with 3× batch freezers in parallel configuration. Evaluate continuous freezer purchase after 6+ months of stable Phase 4 operations, when SKU count is known and run lengths are predictable. Transition to continuous only if the business stabilizes on 2–3 core SKUs with 1,000+ tub/day runs.
Staffing Model (Phase 4, per shift)
- Production Lead / Supervisor (1)
- Mix / Pasteurization Operator (1)
- Batch Freezer Operator (1)
- Filler Operator (1–2)
- Packer / Case Packer (1)
- Warehouse / Forklift (1)
- Sanitation / Utility (1)
Total: 7–8 people
Phase 4 Production Example
| Scenario | Hours/Day | Tubs/Hour | Tubs/Day |
|---|---|---|---|
| Single shift, conservative | 10 | 250 | 2,500 |
| Single shift, efficient | 12 | 200 | 2,400 |
| Two shifts | 16 | 150 | 2,400 |
| Two shifts, high output | 18 | 130 | 2,340 |
Phase 4 Redundancy Level
| Area | Level | Backup Plan | |
|---|---|---|---|
| Pasteurization | High | Backup vat (60-gal or 100-gal) | |
| Batch freezing | Medium/High | Backup batch freezers; emergency co-packer | |
| Filling | High | Backup tabletop filler; manual fallback | |
| Coding | High | Backup handheld coder; printed labels | |
| Labeling | High | Pre-printed tubs | |
| Hardening | Medium | Backup hardening capacity; reduce output | |
| Frozen storage | High | Multiple walk-in zones; 3PL overflow |

Facility Layout Principles
One-directional flow:
Receiving → Storage → Mix Room → Aging → Freezing/Filling → Hardening → Frozen Storage → Shipping
Zones (in order):
- Receiving — incoming dairy, dry ingredients, packaging
- Dry storage — sugar, stabilizers, inclusions, tubs, lids, labels
- Cold ingredient storage — dairy, cream, refrigerated ingredients
- Mix room / hot side — weighing, blending, pasteurization
- Cold aging room — aging tanks, chilled mix staging
- Freezing/filling room — batch freezers, inclusions, filler
- Packaging area — lidding, date coding
- Blast hardening — hardening cabinet or walk-in blast freezer
- Case packing — post-hardening; 12 tubs/case, tape, label, stack
- Finished goods freezer — storage before shipping
- Sanitation/wash area — 3-comp sink, COP/CIP, hose station, chemicals
- Shipping — pallet/case staging and loading
Key rules:
- Never route finished frozen product back through raw ingredient areas
- Keep packaging dry and away from wet processing
- Separate allergens where possible
- Blast hardening close to filling
- Finished freezer close to shipping
- Floor drains in wet areas
- Temperature logging in cold storage, aging, and blast freezing
Daily Production Timelines
Phase 1 (White-Labeling)
No in-house production. Daily activities:
- Receiving and QA inspection of supplier shipments
- Temperature verification and logging
- Inventory rotation (FIFO)
- Repacking / over-labeling if needed
- Order fulfillment and shipping to retail accounts
- Staff: 1–2 people
Phase 2 (500 tubs/day, 3–4 people, Mon–Fri)
Work week: Monday through Friday. No Sunday work. Monday's mix is pasteurized Friday afternoon and ages over the weekend (~40 hrs at 34–40°F). All aging chemistry completes within 12 hours — extended hold is safe and neutral.
Daily cycle (each production day):
- 7:00 AM — Pre-op sanitation, check freezer temps, stage tubs/lids, pull aged mix
- 7:30 AM — Start first batch freeze
- 8:00 AM–1:00 PM — Freeze, add inclusions, fill 14 oz tubs, lid, date code, move to hardening
- 1:00 PM–2:00 PM — CIP (if switching allergen type) or break
- 1:00 PM–3:00 PM — Pasteurize next day's mix (2-hr cycle)
- 3:00 PM–4:00 PM — Case pack hardened product, organize freezer, clean
Weekly rotation:
| Day | Morning (freeze + pack) | Afternoon (pasteurize) |
|---|---|---|
| Monday | Dairy #1 (S'mores Ice Cream) | Tuesday's mix |
| Tuesday | Dairy #2 (PB Ice Cream) | CIP dairy→sorbet + Wednesday's mix |
| Wednesday | Sorbet #3 (Lilikoi Sorbet) | Thursday's mix |
| Thursday | Sorbet #4 (Strawberry Sorbet) | CIP sorbet→dairy |
| Friday | Flex (bestseller top-up or LTO) | Monday's mix → ages ~40 hrs over weekend |
Phase 3 (1,000 tubs/day, 4–6 people)
- 6:00 AM — Pre-op, stage tubs/lids
- 6:30 AM — Start pasteurization or pull aged mix
- 7:00 AM — Start freezing
- 7:30 AM — Start semi-auto filling
- 7:30 AM–12:00 PM — Continuous freeze/fill/harden
- 12:00 PM–12:30 PM — Break/changeover
- 12:30 PM–3:00 PM — Second production block
- 3:00 PM–5:00 PM — Case pack, clean, CIP
Phase 4 (~2,273 14 oz pints/day, 6–8 people)
- 5:00 AM — Pre-op checks, CIP if needed
- 5:30 AM — Pasteurize first batch or pull aged mix
- 6:00 AM — Start continuous or batch freezing
- 6:30 AM — Start semi-auto filling (2-lane)
- 6:30 AM–2:00 PM — Continuous freeze/fill/harden with overlap shifts
- 2:00 PM–2:30 PM — Break/changeover
- 2:30 PM–5:00 PM — Second block or cleanup
- 5:00 PM–6:00 PM — Case pack, CIP, facility prep
Note: Phase 4 may run 2 shifts if continuous freezer is not used. Continuous freezer (scrape-surface barrel) would extend operating hours with fewer changeovers.
