Cooking Kettles, Sauce Blenders & Pet Food Batch Systems

Steam-jacketed cooking kettles, sauce-and-gravy batch vessels, pet food wet-mix blenders, freeze-dry feed tanks, ingredient-metering skids, and complete contract co-packing lines for food and pet food manufacturers.

About Food & Pet Food Processing

Food manufacturing splits cleanly into hot-process and cold-process equipment. Hot-process means cook kettles — steam-jacketed vessels that bring product to target hold temperature for pasteurization, starch gelatinization, or flavor development. Sauce, gravy, broth, stew, soup, jam, jelly, and many ready-meal components run through steam kettles. Tilt kettles pour directly to down-stream fill or hold; fixed kettles pump through a transfer loop. Direct steam injection accelerates heat transfer on high-viscosity product where jacket heat stalls. Scraped-surface kettles prevent burn-on for sticky or high-sugar products.

Cold-process covers every batch mix, blend, and hold step that doesn't require heat. Dressing and condiment batch tanks are agitated emulsifiers for salad dressing, mayonnaise, aioli, and relish. Cold-fill sauce tanks hold finished product from cook-kettle discharge through filler feed, often with glycol-jacket cooling to arrest starch activity. Freeze-dry batch vessels pre-stage product into lyophilization trays or continuous-tray freeze-dry tunnels — a growing segment with the explosion of freeze-dried ingredients in snack, pet food, and nutraceutical product lines.

Pet food deserves its own paragraph: the industry has grown 7–10% annually for 15 years, and premium wet, semi-moist, freeze-dried, and raw-frozen formats demand purpose-built equipment. Wet-mix blenders incorporate protein, starch, fat, and functional ingredients into a pumpable slurry that feeds extrusion or canning lines. Gravy-and-sauce kettles produce the wet phase of complete-meal pet food cans. Frozen-raw batch mixers blend ground protein and supplement packs for direct-to-consumer frozen-raw brands. Ingredient-metering skids dose minor ingredients (vitamin pre-mix, probiotic culture, flavor) at gram-level accuracy into primary-ingredient streams.

What We Fabricate

Extrusion Conditioning Tanks

Pre-extruder conditioning vessels for pet-food kibble production.

Contract Co-Pack Lines

Complete turnkey blend-batch-fill-palletize packages for contract food manufacturers.

How a Custom Project Works

  1. Requirements capture. Volume, materials of construction, service chemistry, operating temperature and pressure, footprint, utility connections, finish, and any code or certification requirements. We work from your specification or draft one against your process.
  2. Engineering and drawings. A general-arrangement drawing, bill of materials, and weld map — reviewed and signed off before any material is cut.
  3. Material procurement. Plate, pipe, fittings, and elastomers ordered to the approved bill of materials, with material certifications captured where the service demands traceability.
  4. Fabrication. Shells formed and welded, heads and ports installed per drawing, sanitary work TIG-welded and ground flush on product-contact surfaces.
  5. Inspection and testing. Weld examination, pressure or leak testing as applicable, surface-finish verification, and passivation to ASTM A967 on stainless.
  6. Documentation and shipment. Material certifications, weld and inspection records, and test certificates compiled for handoff. Shipment with blocking and bracing; freight quoted separately to your ZIP.

Frequently Asked Questions

Direct steam injection or jacket heat?
Jacket heat is clean and well-controlled but slow on high-viscosity or high-solids product. Direct steam injection adds 10–15% water to the batch but achieves target temp in a fraction of the time — best for soup, broth, and gravy where added water is tolerable. Scraped-surface kettles solve the high-viscosity heating problem without water addition.
Is a tilt kettle or fixed kettle better?
Tilt kettles (50-gal through ~200-gal) pour directly to downstream packaging and simplify cleanup. Fixed kettles (150-gal and up) require a transfer pump but handle larger volumes and integrate into CIP loops more cleanly.
Can you build a pet food wet-mix line?
Yes. Complete lines include ingredient-metering skids, wet-mix blenders, gravy kettles, conditioning tanks, and retort feed vessels — sized to your target case throughput.
What's the lead time on a complete co-pack line?
Typical lead time on a turnkey blend-batch-fill-palletize line is 22–36 weeks from signed drawings through FAT and commissioning. Individual vessels within the package ship on shorter lead times.
